Full Text Available Background and Aim. Aparallel, randomized, double blinded, placebo-controlled trial study was designed to assess the efficacy of single low dose of intravenous magnesium sulfate on post-total abdominal hysterectomy (TAH pain relief under balanced general anesthesia. Subject and Methods. Forty women undergoing TAH surgery were assigned to two magnesium sulfate (N=20 and normal saline (N=20 groups randomly. The magnesium group received magnesium sulfate 50 mg·kg−1 in 100 mL of normal saline solution i.v as single-dose, just 15 minutes before induction of anesthesia whereas patients in control group received 100 mL of 0.9% sodium chloride solution at the same time. The same balanced general anesthesia was induced for two groups. Pethidine consumption was recorded over 24 hours precisely as postoperative analgesic. Pain score was evaluated with Numeric Rating Scale (NRS at 0, 6, 12, and 24 hours after the surgeries. Results. Postoperative pain score was lower in magnesium group at 6, 12, and 24 hours after the operations significantly (P<0.05. Pethidine requirement was significantly lower in magnesium group throughout 24 hours after the surgeries (P=0.0001. Conclusion. Single dose of magnesium sulfate during balanced general anesthesia could be considered as effective and safe method to reduce postoperative pain and opioid consumption after TAH.

Full Text Available Abstract Background Intramuscular pethidine is routinely used throughout the UK for labour analgesia. Studies have suggested that pethidine provides little pain relief in labour and has a number of side effects affecting mother and neonate. It can cause nausea, vomiting and dysphoria in mothers and can cause reduced fetal heart rate variability and accelerations. Neonatal effects include respiratory depression and impaired feeding. There are few large studies comparing the relative side effects and efficacy of different opioids in labour. A small trial comparing intramuscular pethidine with diamorphine, showed diamorphine to have some benefits over pethidine when used for labour analgesia but the study did not investigate the adverse effects of either opioid. Methods The Intramuscular Diamorphine versus Intramuscular Pethidine (IDvIP trial is a randomised double-blind two centre controlled trial comparing intramuscular diamorphine and pethidine regarding their analgesic efficacy in labour and their side effects in mother, fetus and neonate. Information about the trial will be provided to women in the antenatal period or in early labour. Consent and recruitment to the trial will be obtained when the mother requests opioid analgesia. The sample size requirement is 406 women with data on primary outcomes. The maternal primary outcomes are pain relief during the first 3 hours after trial analgesia and specifically pain relief after 60 minutes. The neonatal primary outcomes are need for resuscitation and Apgar Score Discussion If the trial demonstrates that diamorphine provides better analgesia with fewer side effects in mother and neonate this could lead to a change in national practice and result in diamorphine becoming the preferred intramuscular opioid for analgesia in labour.

To compare the incidence of repeated red blood cell (RBC) transfusion in anemic gynecologic cancer patients receiving platinum-based chemotherapy comparing intravenous and oral iron. Forty-four anemic gynecologic cancer patients (hemoglobin level below 10 mg/dl) who required RBC transfusion were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. Study group received 200 mg of intravenous iron sucrose and control group received oral ferrous sulphate 600 mg/day. RBC transfusion requirement in the consecutive cycle of chemotherapy was the primary outcome. Quality of life was evaluated by validated Thai version of the Functional Assessment of Cancer Therapy-Anemia (FACT-An). In a total of the 44 patients, there were 22 patients in each group. Five patients (22.7%) in the study group and 14 patients (63.6%) in the control group required RBC transfusion in consecutive cycle of chemotherapy (p=0.01). No significant difference in baseline hemoglobin and hematocrit levels was demonstrated in both groups. Significantly higher mean hemoglobin and hematocrit levels after treatment were reported in the study group (10.0+/-0.8 g/dl and 30.5+/-2.4%) than the control group (9.5+/-0.9 g/dl and 28.4+/-2.7%). No significant change of total FACT-An scores was noted between before and after treatment in both groups. No serious adverse events were reported and there was no significant difference among adverse events between both groups. Intravenous iron is an alternative treatment for anemic gynecologic cancer patients receiving platinum-based chemotherapy and reduces the incidence of RBC transfusion without serious adverse events.

BACKGROUND: Preclinical studies demonstrate renal proximal tubular injury after administration of some intravenous iron preparations but clinical data on renal effects of intravenous iron are sparse. METHODS: FIND-CKD was a 56-week, randomized, open-label, multicenter study in which patients...... with non-dialysis dependent chronic kidney disease (ND-CKD), anemia and iron deficiency without erythropoiesis-stimulating agent therapy received intravenous ferric carboxymaltose (FCM), targeting either higher (400-600 μg/L) or lower (100-200 μg/L) ferritin values, or oral iron. RESULTS: Mean (SD) e...... quartiles of FCM dose, change in ferritin or change in TSAT versus change in eGFR. Dialysis initiation was similar between groups. Renal adverse events were rare, with no indication of between-group differences. CONCLUSION: Intravenous FCM at doses that maintained ferritin levels of 100-200 μg/L or 400...

Our pediatric medical ward administers an average of 80 intravenous injections to preschool children. We found that 91.1% exhibit behavior indicative of fear and anxiety. Over three-quarters (77.8%) of this number suffer severe fear and actively resist receiving injections. Such behavior places a greater than normal burden on human and material resources and often gives family members negative impressions that lower their trust in the healthcare service while raising nurse-patient tensions. Using observation and interviews, we found primary factors in injection fear to be: Past negative experiences, lack of adequate prior communication, measures taken to preemptively control child resistance, and default cognitive behavioral strategies from nursing staff. This project worked to develop a strategy to reduce cases of severe injection fear in preschool children from 77.8% to 38.9% and achieve a capacity improvement target for members of 50%. Our team identified several potential strategy solutions from research papers and books between August 1st, 2009 and April 30th, 2010. Our proposed method included therapeutic games, self-selection of injection position, and cognitive behavioral strategies to divert attention. Other measures were also specified as standard operating procedures for administering pediatric intravenous injections. We applied the strategy on 45 preschool children and identified a post-injection "severe fear" level of 37.8%. This project was designed to reduce fear in children to make them more accepting of vaccinations and to enhance children's positive treatment experience in order to raise nursing care quality.

Can Spinal Bupivacaine Analgesia Treatment Make a Difference on Urinary Bladder Healing According to the Intramuscular Pethidine Analgesia Treatment in Rats?

Full Text Available We designed a study to compare the healing levels found with intramuscular pethidine with those found with intrathecal local anesthetic treatments. The urinary bladder is suggested to be the most useful tissue in the evaluation of the effects of the drugs. Nineteen male, Sprague-Dawley rats weighing 200–300 g were used in this study. A sagittal section was made in the urinary bladder after suitable anesthesia and laparotomy. Bladders were closed with 5-0 plain catguts 5 min later. There were nine rats in the control group and pethidine (0.5 g/kg was administered intramuscularly in the gluteal muscle region to treat pain after the operations. There were 11 rats in the study group and each received a spinal injection of 0.25% bupivacaine after the operation. Rats were followed for 7 days to define pain. Specimens, particularly the incised region of the bladder, were evaluated for inflammation and fibrosis. Grading scales were used for this purpose. Statistical analyses of the data were performed using the Chi-square test. Statistical analyses were nonsignificant for inflammation (p ≤ 0.151 and nonsignificant for fibrosis (p ≤ 0.105. The treatments may have the same effects on organ healing mechanisms. Statistical difference is not shown in this study, but use of other combinations of pain treatments to evaluate the healing may demonstrate which of these possibilities is true.

To compare the efficacy of intravenous iron and oral iron for prevention of blood transfusions in gynecologic cancer patients receiving platinum-based chemotherapy. Sixty-four non anemic gynecologic cancer patients receiving adjuvant platinum-based chemotherapy were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. The study group received 200mg of intravenous iron sucrose immediately after each chemotherapy infusion. The control group received oral ferrous fumarate at a dose of 200mg three times a day. Complete blood count was monitored before each chemotherapy infusion. Blood transfusions were given if hemoglobin level was below 10mg/dl. There were 32 patients in each group. No significant differences in baseline hemoglobin levels and baseline characteristics were demonstrated between both groups. Nine patients (28.1%) in the study group and 18 patients (56.3%) in the control group required blood transfusion through 6 cycles of chemotherapy (p=0.02). Fewer median number of total packed red cell units were required in the study group compared to the control group (0 and 0.5 unit, respectively, p=0.04). Serious adverse events and hypersensitivity reactions were not reported. However, constipation was significantly higher in the control group (3.1% and 40.6%, p=gynecologic cancer patients receiving platinum-based chemotherapy, associated with less constipation than the oral formulation. © 2013 Elsevier Inc.

Erythropoiesis-stimulating agents (ESAs) are often used in treatment of patients with chemotherapy-induced anemia. Many studies have demonstrated an improved hemoglobin (Hb) response when ESA is combined with intravenous iron supplementation and a higher effectiveness of intravenous iron over traditional oral iron formulations. A new formulation of oral sucrosomial iron featuring an increased bioavailability compared to traditional oral formulations has recently become available and could provide a valid alternative to those by intravenous (IV) route. Our study evaluated the performance of sucrosomial iron versus intravenous iron in increasing hemoglobin in anemic cancer patients receiving chemotherapy and darbepoetin alfa, as well as safety, need of transfusion, and quality of life (QoL). The present study considered a cohort of 64 patients with chemotherapy-related anemia (Hb >8 g/dL iron deficiency, scheduled to receive chemotherapy and darbepoetin. All patients received darbepoetin alfa 500 mcg once every 3 weeks and were randomly assigned to receive 8 weeks of IV ferric gluconate 125 mg weekly or oral sucrosomial iron 30 mg daily. The primary endpoint was to demonstrate the performance of oral sucrosomial iron in improving Hb response, compared to intravenous iron. The Hb response was defined as the Hb increase ≥2 g/dL from baseline or the attainment Hb ≥ 12 g/dL. There was no difference in the Hb response rate between the two treatment arms. Seventy one percent of patients treated with IV iron achieved an erythropoietic response, compared to 70% of patients treated with oral iron. By conventional criteria, this difference is considered to be not statistically significant. There were also no differences in the proportion of patients requiring red blood cell transfusions and changes in QoL. Sucrosomial oral iron was better tolerated. In cancer patients with chemotherapy-related anemia receiving darbepoetin alfa, sucrosomial oral iron provides

Full Text Available Intravenous sedation during colonoscopy has become the standard practice in the United States given its higher patient satisfaction and procedural quality. This practice is not free of side effects as a significant proportion of patients undergoing this procedure tend to have respiratory depression and desaturation events. Obesity, as it relates to higher levels of body mass index (BMI has a positive correlation with the incidence of hypoxemia. During colonoscopy High flow nasal cannula (HFNC may potentially improve oxygen performance in patients receiving colonoscopy under intravenous sedation. Here we present 3 cases of patients undergoing adjunctive oxygen therapy with HFNC during colonoscopy with intravenous sedation. We found patients to have lower number of desaturation events and were satisfied with their experience.

In 38 patients buprenorphine, meperidine and pentazocine were given in a single dose for postoperative pain relief 20 hours after the end of anaesthesia. Measuring the parameters of the high- and low-pressure system as well as the metabolism the authors found that the effects of these analgetic medicaments, intravenously injected were significantly influenced by fentanyl, halothane or diazepam, given under the course of operation. Especially buprenorphine, injected after epidural anaesthesia in combination with diazepam sedation, proved to have a rather negative effect, because it caused a strong depression of respiration and circulation. On the other hand buprenorphine had, given after neuroleptanaesthesia, a neutralizing - and pentazocine and pethidine in combination with neuroleptanaesthesia a stimulating influence on the circulation. After halothane-anaesthesia the effect of the analegtics on the cardiovascular system was, when buprenorphine was given, depressing and when pentazocine was given indifferent. Similar reactions, but more pronounced, could be seen in the epidural group. With certain reservations, caused by the preliminary character of this study, the following conclusions can be drawn for the anaesthetic practice: 1 Choosing analgetic drugs for postoperative pain relief, the anaesthesist has to be aware of the interactions, possibly resulting from the medicaments, given during anaesthesia. 2. The number of medicaments, given during anaesthesia, should be kept small, considering the eventual interactions and the unintentional secondary effects.

Empirical antibiotics at the onset of febrile neutropenia are one of several strategies for management of bacterial infections in patients undergoing Hematopoietic Stem Cell Transplant (HSCT) (empiric strategy). Our HSCT program aims to perform HSCT in an outpatient setting, where an empiric antibiotic strategy was employed. HSCT recipients began receiving intravenous antibiotics at the onset of neutropenia in the absence of fever as part of our institutional policy from 01 Jan 2009; intravenous Prophylactic strategy. A prospective study was conducted to compare two consecutive cohorts [Year 2008 (Empiric strategy) vs. Year 2009 (Prophylactic strategy)] of patients receiving HSCT. There were 238 HSCTs performed between 01 Jan 2008 and 31 Dec 2009 with 127 and 111 in the earlier and later cohorts respectively. Infection-related mortality pre- engraftment was similar with a prophylactic compared to an empiric strategy (3.6% vs. 7.1%; p = 0.24), but reduced among recipients of autologous HSCT (0% vs. 6.8%; p = 0.03). Microbiologically documented, blood stream infections and clinically documented infections pre-engraftment were reduced in those receiving a prophylactic compared to an empiric strategy, (11.7% vs. 28.3%; p = 0.001), (9.9% vs. 24.4%; p = 0.003) and (18.2% vs. 33.9% p = 0.007) respectively. The prophylactic use of intravenous once-daily ceftriaxone in patients receiving outpatient based HSCT is safe and may be particularly effective in patients receiving autologous HSCT. Further studies are warranted to study the impact of this Prophylactic strategy in an outpatient based HSCT program. PMID:23029441

The efficacy and toxicity of sequential intravenous and oral ciprofloxacin therapy was compared with intravenously administered ceftazidime in a prospective, randomized, controlled, non-blinded trial. Thirty-two patients (16 patients receiving ciprofloxacin and 16 patients receiving ceftazidime) with 38 infections caused by susceptible Pseudomonas aeruginosa, enteric gram-negative rods, Salmonella group B, Serratia marcescens, Pseudomonas cepacia, and Xanthomonas maltophilia at various sites were evaluable for determination of efficacy. Length of therapy varied from seven to 25 days. Concomitant antimicrobials included intravenously administered beta-lactams for gram-positive organisms, intravenous/oral metronidazole and clindamycin for anaerobes, and intravenous/local amphotericin B for Candida albicans. Intravenous administration of 200 mg ciprofloxacin every 12 hours to 11 patients produced peak serum levels between 1.15 and 3.12 micrograms/ml; trough levels ranged between 0.08 and 0.86 micrograms/ml. Overall response rates were similar for patients receiving ciprofloxacin and ceftazidime. Emergence of resistance was similar in both groups--one Enterobacter cloacae and two P. aeruginosa became resistant after ciprofloxacin therapy and two P. aeruginosa became resistant after ceftazidime therapy. The frequency of superinfection with a variety of organisms was also similar in both groups. Adverse events related to ciprofloxacin included transient pruritus at the infusion site and generalized rash leading to drug discontinuation (one patient each), and with ceftazidime adverse effects included pain at the site of infusion and the development of allergic interstitial nephritis (one patient each). Overall, intravenous/oral ciprofloxin therapy appears to be as safe and effective as intravenous ceftazidime therapy in the treatment of a variety of infections due to susceptible aerobic gram-negative organisms.

Reducing health care costs without adversely affecting patient safety is a constant challenge for health care institutions. Cefazolin prophylaxis via intravenous push (IVP) is more cost-effective than via intravenous piggyback (IVPB). The purpose of this study was to determine whether patient safety would be compromised (ie, an increased rate of phlebitis) with a change to the IVP method. Rates of phlebitis in orthopedic surgical patients receiving cefazolin prophylaxis via IVP versus IVPB were evaluated in a prospective quasi-experimental design of 240 patients. The first 120 subjects received cefazolin via IVPB, and the second 120 subjects received it via IVP. Results indicated no statistically significant difference in phlebitis rates in the IVPB (3.4%) versus the IVP groups (3.3%).

Intravenous (IV) acetaminophen may be an effective component of multimodal postoperative pain management. The primary objective of this study was to evaluate the impact of IV acetaminophen on total opioid use in postoperative patients. The secondary objective was to evaluate the effect of IV acetaminophen on hospital length of stay. This retrospective, case-control study evaluated the impact of IV acetaminophen on total opioid use in surgical patients. Patients were included if they received at least one perioperative dose of IV acetaminophen and underwent a surgical knee procedure. Controls were matched and randomly selected based on procedure type, age, and severity of illness. Postoperative opioids were converted into oral morphine equivalents, and overall use was compared between groups. One hundred patients were enrolled, with 25 patients receiving IV acetaminophen and 75 matched controls. A total of 135 mg versus 112.5 mg oral morphine equivalents were used in the IV acetaminophen group and control group, respectively (p=0.987). There were 45 mg/day oral morphine equivalents used in the IV acetaminophen group versus 37.5 mg in the control group (p=0.845). The median hospital length of stay in both groups was 3 days (p=0.799). IV acetaminophen did not significantly decrease postoperative opioid use in patients who underwent surgical knee procedures. In addition, there was a nonsignificant trend toward increased opioid use in the IV acetaminophen group. There was no significant difference in hospital length of stay between the IV acetaminophen group and the control group. These findings require further study in larger patient populations and in other orthopedic procedures that typically require longer hospital stays. © 2014 Pharmacotherapy Publications, Inc.

The DRAGON score, which includes clinical and computed tomographic (CT) scan parameters, predicts functional outcomes in ischemic stroke patients treated with intravenous tissue plasminogen activator (IV tPA). We assessed the utility of the DRAGON score in predicting functional outcome in stroke patients receiving both IV tPA and endovascular therapy. A retrospective chart review of patients treated at our institution from February 2009 to October 2015 was conducted. All patients with computed tomography angiography (CTA) proven large vessel occlusions (LVO) who underwent intravenous thrombolysis and endovascular therapy were included. Baseline DRAGON scores and modified Rankin Score (mRS) at the time of hospital discharge was calculated. Good outcome was defined as mRS ≤3. Fifty-eight patients with LVO of the anterior circulation were studied. The mean DRAGON score of patients on admission was 5.3 (range, 3-8). All patients received IV tPA and endovascular therapy. Multivariate analysis demonstrated that DRAGON scores ≥7 was associated with higher mRS ( P DRAGON scores ≤6. Patients with DRAGON scores of 7 and 8 on admission had a mortality rate of 3.8% and 40%, respectively. The DRAGON score can help predict better functional outcomes in ischemic stroke patients receiving both IV tPA and endovascular therapy. This data supports the use of the DRAGON score in selecting patients who could potentially benefit from more invasive therapies such as endovascular treatment. Larger prospective studies are warranted to further validate these results.

The aim of this prospective study was to determine the efficacy of intraarticular levobupivacaine with and without intravenous dexketoprofen trometamol for postarthroscopy analgesia. Sixty patients who underwent arthroscopic knee surgery were randomly assigned to three treatment groups. When the surgical procedure was completed, patients received the following treatments: group I (n = 20) patients received 20 mL intraarticular normal saline and 2 mL intravenous dexketoprofen trometamol (50 mg); group II (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous normal saline; and group III (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous dexketoprofen trometamol (50 mg). The visual analogue scale (VAS) was used, and the total analgesic consumption was assessed at 1, 2, 4, 6, 12, and 24 h post-operatively. The VAS scores at 1, 2, 4, 6, 12, and 24 h post-operatively were significantly increased in group I and group II compared with group III (p dexketoprofen trometamol administration provided better pain relief and less analgesic requirement after arthroscopic knee surgery during the first 24 h than that induced by dexketoprofen alone or levobupivacaine intraarticular alone.

Full Text Available This research has focused on the birthing experience of first-time mothers who received the narcotic analgesic combination of Pethidine and Hydroxyzine during the first stage of labour. A qualitative research methodology was used to collect data. Unstructured interviews were held with first-time mothers to obtain accounts of their experience of childbirth. These narrations were audio-taped while the participants were still being cared for in the postnatal ward of the hospital where delivery took place. Nine interviews were conducted with first-time mothers who gave birth normally vaginally after a normal pregnancy and who received a narcotic analgesic in the first stage of labour. The transcribed interviews were analyzed using Tesch’s method of descriptive analysis (in Creswell, 1994:115.

To discover the views of children with severe intestinal failure treated with intravenous nutrition from early life and who remained heavily dependent on treatment throughout childhood. Seven children ages 7 to 17 years (mean 13 years) were interviewed. The diagnoses were enteropathy in 3, extreme short gut in 1, complex (associated mucosal inflammation and dysmotitlity) in 2, and intestinal pseudo-obstruction in 1. They were treated with intravenous nutrition overnight at home that was administered by trained parents using the simplest possible system. The children were individually questioned about their lifestyle and health. Transcripts were analysed using interpretive phenomenological analysis. Children coped well with life with intravenous nutrition (apart from septicaemia in 2 cases), but were troubled when complications of the underlying disease persisted (eg, nocturnal disturbance, stool frequency, abdominal pain). Children were aware that life was restricted (eg, fewer sleepovers with friends, fewer late nights out). There was a high level of family functioning. Older children wished to take care of themselves. The burdens of life with intravenous nutrition appear to be less significant for these children than living with the effects of chronic illness. There was resilience and acceptance in the face of illness-related demands. This study has found that despite the problems they may face, it is possible for children fed intravenously at home to develop a level of resilience, maintain a positive outlook, and cope well with illness-related demands even when they have had virtually lifelong severe intestinal failure. Families can continue to function well.

Full Text Available Background: Different methods and many drugs have been used to control the post-operative pain. In this study, we evaluate the role of gabapentin premedication and/or dexamethasone in management of post-operative pain following adenotonsillectomy in children. Materials and Methods: In a double-blind randomized study, 120 children were subjected for adenotonsillectomy classified into three equal groups. Group G: Gabapentin 10 mg/kg was given orally 2 h before induction of anesthesia (Gabapentin syrup 250 mg/5 ml. Group D: Children in this group received placebo pre-operatively and received dexamethasone 0.15 mg/kg intravenously after induction of anesthesia, but before surgery. Group C: Children in this group received combination of oral gabapentin 10 mg/kg 2 h before induction of anesthesia and intra-operative 0.15 mg/kg dexamethasone intravenously. All children underwent general anesthesia. Pain score was assisted post-operatively 2 h, 4 h, 6 h, 8 h, 12 h and 18 h after recovery using face, legs, activity, cry, consolability scale. Results: Pain score in Group C and Group G was significantly less at 4 h, 6 h and 8 h post-operatively than in Group D (P 0.05. The time to first analgesia was longer in the Group C than in Group G and Group D and the time to first analgesia was significantly longer in Group G than in Group D (P < 0.05. The total amount of pethidine was less in Group C and Group G than in Group D (P < 0.05. The incidence of post-operative nausea and vomiting was statically insignificant among all groups and no reported post-operative bleeding. Conclusion: Gabapentin 10 mg/kg premedication combined with intra-operative dexamethasone 0.15 mg/kg prolongs the post-operative analgesia following adenotonsillectomy in children and decreases the amount of pethidine used post-operatively with no reported adverse effects or increase in the incidence of post-operative bleeding.

To assess the knowledge of prescribers regarding intravenous to oral conversions of fluoroquinolones, the frequency and time until conversion, and to compare prescriber knowledge with the data collected concerning the reasons stated for continuation of intravenous fluoroquinolones. Prospective chart review and questionnaire. Large teaching hospital in Paris, France. Fifty-one males and females. Data were collected on in-patients receiving intravenous fluoroquinolone for at least three days and hospitalized in one of six in-patient units. Patients receiving intravenous fluoroquinolone for less than three days were excluded. A questionnaire to assess the awareness of a potential conversion was distributed to those practitioners who had patients reviewed during the data-collection phase. The questionnaire revealed the ten most common reasons for continuing intravenous administration for more than three days. However, the physicians agreed that most patients should be converted as soon as possible. Practice patterns differed, with only 17 of 51 patients actually converted to oral therapy. In theory, the clinicians were aware of when to perform the conversion. However, in practice, the frequency of conversion was lower than optimum. Changes in clinical practice are needed to decrease the costs of intravenous therapy, without jeopardizing quality of care.

A method for preparing a stable, dry-packaged, sterile, nutrient composition which upon addition of sterile, pyrogen-free water is suitable for intravenous administration to a mammal, including a human, is described. The method comprises providing the nutrients in a specific dry form and state of physical purity acceptable for intravenous administration, sealing the nutrients in a particular type of container adapted to receive and dispense sterile fluids and subjecting the container and its sealed contents to a sterilizing, nondestructive dose of ionizing radiation. The method results in a packaged, sterile nutrient composition which may be dissolved by the addition of sterile pyrogen-free water. The resulting aqueous intravenous solution may be safely administered to a mammal in need of nutrient therapy. The packaged nutrient compositions of the invention exhibit greatly extended storage life and provide an economical method of providing intravenous solutions which are safe and efficacious for use.

Several features favor paracetamol (acetaminophen) administration by the intravenous rather than the oral route in the postoperative setting. This study compared the pharmacokinetics and bioavailability of oral and intravenous paracetamol when given with or without an opioid, morphine. In this randomized, single-blind, parallel, repeat-dose study in healthy adults, subjects received four repeat doses of oral or intravenous 1000 mg paracetamol at 6-h intervals, and morphine infusions (0.125 mg/kg) at the 2nd and 3rd intervals. Comparisons of plasma pharmacokinetic profiles were conducted before, during, and after opioid co-administrations. Twenty-two subjects were included in the pharmacokinetic analysis. Observed paracetamol peak concentration (C max ) and area under the plasma concentration-time curve over the dosing interval (AUC 0-6 ) were reduced when oral paracetamol was co-administered with morphine (reduced from 11.6 to 7.25 µg/mL and from 31.00 to 25.51 µg·h/mL, respectively), followed by an abruptly increased C max and AUC 0-6 upon discontinuation of morphine (to 13.5 µg/mL and 52.38 µg·h/mL, respectively). There was also a significantly prolonged mean time to peak plasma concentration (T max ) after the 4th dose of oral paracetamol (2.84 h) compared to the 1st dose (1.48 h). However, pharmacokinetic parameters of paracetamol were not impacted when intravenous paracetamol was co-administered with morphine. Morphine co-administration significantly impacted the pharmacokinetics of oral but not intravenous paracetamol. The abrupt release of accumulated paracetamol at the end of morphine-mediated gastrointestinal inhibition following oral but not intravenous administration of paracetamol suggests that intravenous paracetamol provides a better option for the management of postoperative pain.

We aimed to evaluate the impact of physicians' educational programs in the reduction of inappropriate intravenous lines in internal medicine. Fifty-six French internal medicine units were enrolled in a nationwide, prospective, blinded, randomized controlled trial. Forms describing the patients with an intravenous line and internal medicine department characteristics were filled out on 2 separate days in January and April 2007. Following the first visit, all units were randomly assigned to either a specific education program on the appropriate indications of an intravenous line, during February and March 2007, or no training (control group). The Investigators' Committee then blindly evaluated the clinical relevance of the intravenous line according to pre-established criteria. The primary outcome was the percentage of inappropriate intravenous lines. During January 2007, intravenous lines were used in 475 (24.9%) of the 1910 hospitalized patients. Of these, 80 (16.8%) were considered inappropriate. In April 2007, 416 (22.8%) of the 1823 hospitalized patients received an intravenous line, which was considered in 10.2% (21/205) of patients managed by trained physicians, versus 16.6% (35/211) of patients in the control group (relative difference 39%; 95% confidence interval, -0.6-13.3; P = .05). Reduced intravenous administration of fluids, antibiotics, and analgesics accounted for the observed decrease. The use of a simple education program reduced the rate of inappropriate intravenous lines by almost 40% in an internal medicine setting (NCT01633307). Copyright © 2013 Elsevier Inc.

Gastric absorption of oral paracetamol (acetaminophen) may be unreliable perioperatively in the starved and stressed patient. We compared plasma concentrations of parenteral paracetamol given preoperatively and oral paracetamol when given as premedication. Patients scheduled for elective ear; nose and throat surgery or orthopaedic surgery were randomised to receive either oral or intravenous paracetamol as preoperative medication. The oral dose was given 30 minutes before induction of anaesthesia and the intravenous dose given pre-induction. All patients were given a standardised anaesthetic by the same specialist anaesthetist who took blood for paracetamol concentrations 30 minutes after the first dose and then at 30 minute intervals for 240 minutes. Therapeutic concentrations of paracetamol were reached in 96% of patients who had received the drug parenterally, and 67% of patients who had received it orally. Maximum median plasma concentrations were 19 mg.l(-1) (interquartile range 15 to 23 mg.l(-1)) and 13 mg.l(-1) (interquartile range 0 to 18 mg.l(-1)) for the intravenous and oral group respectively. The difference between intravenous and oral groups was less marked after 150 minutes but the intravenous preparation gave higher plasma concentrations throughout the study period. It can be concluded that paracetamol gives more reliable therapeutic plasma concentrations when given intravenously.

Objective: To evaluate the curative effect of the two successful therapeatic methods on myocardial infarction in the acute and long-term stage: percutaneous coronary intenvention(PCI) and intravenous thrombolysis therapy. Methods: Fifty-six patients of acute myocardial infarction were studied. There was no record of heart failure occurence in the case history for all of them. We randomly assigned them to receive PCI or intravenous thrombolysis therapy, and all of them are treated successfully. Left ventricule ejection fraction (LVEF) and left ventricule end diastole diameter(LVEDD) measured by echocardiography were analyzed. Clinical information about death caused by cardial origin problems were collected and the mean survival days of the patients were 548.7 ± 48.9. Results: The total of 27 patients were assigned to undergo PCI and 29 patients received intravenous thrombolysis therapy. LVEF patients with PCI were 57.6% ± 2.3%, and patients with intravenous thrombolysis therapy were 49.9% ± 1.9%. There were significant difference between the two groups(P 0.5). 548.7 ± 48.9 days survival was accounted for 85.2% in the PCI group, and 79.3% in the intravenous thrombolysis therapy (P>0.5). Multivariate analysis showed that older age, LVEF, were related to 548.7 ± 48.9 days mortality. Conclusion: The results of this study show more acute stage benefit patients treated with PCI using bare stant than those treated with intravenous thrombolysis therapy; But it indicates that there is no more long-term survival for patients treated with PCI by using bare stant compared with those who received intravenous thrombolysis therapy in the patients with light or medium acute myocardial infarction.

Purpose: To examine the clinical significance of persistent renal enhancement after iodixanol administration. Methods: We retrospectively studied 166 consecutive patients who underwent non-enhanced abdominopelvic CT within 7 days after receiving intra-arterial (n = 99) or intravenous (n = 67) iodixanol. Renal attenuation was measured for each non-enhanced CT scan. Persistent renal enhancement was defined as CT attenuation >55 Hounsfield units (HU). Contrast-induced nephropathy (CIN) was defined as a rise in serum creatinine >0.5 mg/dL within 5 days after contrast administration. Results: While the intensity and frequency of persistent renal enhancement was higher after intra-arterial (mean CT attenuation of 73.7 HU, seen in 54 of 99 patients, or 55%) than intravenous contrast material administration (51.8 HU, seen in 21 of 67, or 31%, p < 0.005), a multivariate regression model showed that the independent predictors of persistent renal enhancement were a shorter time interval until the subsequent non-enhanced CT (p < 0.001); higher contrast dose (p < 0.001); higher baseline serum creatinine (p < 0.01); and older age (p < 0.05). The route of contrast administration was not a predictor of persistent renal enhancement in this model. Contrast-induced nephropathy was noted in 9 patients who received intra-arterial (9%) versus 3 who received intravenous iodixanol (4%), and was more common in patients with persistent renal enhancement (p < 0.01). Conclusion: Persistent renal enhancement at follow-up non-contrast CT suggests a greater risk for contrast-induced nephropathy, but the increased frequency of striking renal enhancement in patients who received intra-arterial rather than intravenous contrast material also reflects the larger doses of contrast and shorter time to subsequent follow-up CT scanning for such patients.

We investigated the postoperative analgesic efficacy and effect on total tramadol consumption of intravenous dexketoprofen trometamol, a new nonsteroidal anti-inflammatory drug, in patients that had undergone lumbar disc surgery. Sixty patients were included in this placebo-controlled, randomized, double-blind study. General anesthesia was applied to both groups. Group D (n=30) received dexketoprofen (50 mg) intravenously 30 minutes before the end of surgery and at the postoperative 12th hour, whereas group C (n=30) received 2 mL of 0.9% NaCL intravenously at the same time points. All patients received a patient controlled analgesia device with a tramadol, 25 mg bolus, 15 minutes lockout protocol, and were followed with visual analog scale, verbal rating scale, modified Aldrete recovery scoring system, and Ramsay sedation scale in the postoperative period. There was no significant difference between the groups for demographic data, duration of surgery, mean arterial pressure, and heart rate. The time to first postoperative analgesic requirement was significantly longer in group D (151.33±81.98 min) than group C (19±5.78 min) (Pdexketoprofen was an effective analgesic for postdiscectomy pain when used alone or in addition to opioids. It is easy to administer and decreases tramadol consumption and opioid-related side effects.

Incarcerated intravenous heroin users have more problematic patterns of heroin use, but are less likely to access methadone maintenance treatment by their own initiative than heroin users in the community. The present study examined predictors for receiving methadone maintenance treatment post-release among incarcerated intravenous heroin users within a 24-month period. This cohort study recruited 315 incarcerated intravenous heroin users detained in 4 prisons in southern Taiwan and followed up within the 24-month period post-release. Cox proportional hazards regression analysis was applied to determine the predictive effects of sociodemographic and drug-use characteristics, attitude toward methadone maintenance treatment, human immunodeficiency virus serostatus, perceived family support, and depression for access to methadone maintenance treatment after release. There were 295 (93.7%) incarcerated intravenous heroin users released that entered the follow-up phase of the study. During the 24-month follow-up period, 50.8% of them received methadone maintenance treatment. After controlling for the effects of the detainment period before and after recruitment by Cox proportional hazards regression analysis, incarcerated intravenous heroin users who had positive human immunodeficiency virus serostatus (HR = 2.85, 95% CI = 1.80-4.52, p maintenance treatment before committal (HR = 1.94, 95% CI = 1.23-3.05, p maintenance treatment within the 24-month follow-up period. Positive human immunodeficiency virus serostatus with fully subsidized treatment and previous methadone maintenance treatment experiences predicted access of methadone maintenance treatment post-release. Strategies for getting familiar with methadone maintenance treatment during detainment, including providing methadone maintenance treatment prior to release and lowering the economic burden of receiving treatment, may facilitate entry of methadone maintenance treatment for incarcerated intravenous heroin

Full Text Available Background Glucose-6-phosphate dehydrogenase deficiency alone or concomitant with ABO isoimmunisation is a widespread indication for neonatal exchange transfusion. Aims To evaluate the effectiveness of Intravenous Immunoglobulin in the treatment of neonatal hyperbilirubinemia due to glucose-6-phosphate dehydrogenase deficiency. Methods A retrospective cohort study was conducted between 2006 and 2014 at the Jordan University of Science and technology. The medical records of 43 infants admitted to the neonatal intensive care unit for isolated glucose-6- phosphate dehydrogenase deficiency hemolytic disease of the newborns were reviewed. Patients were divided into two groups. Group I, a historical cohort, included newborns born between 2006 and 2010, Treatment included phototherapy and exchange transfusion. Group II included newborns born between 2011 and 2014, where, in addition to phototherapy, intravenous immunoglobulin was administered. The duration of phototherapy and number of exchange transfusions were evaluated. Results Of 412 newborns that were admitted with neonatal hyperbilirubinemia, Glucose-6-phosphate dehydrogenase deficiency was present in 43. Of these, 22, did not receive intravenous immunoglobulin and served as a control group. The other 21 newborns received intravenous immunoglobulin. There was no difference in the demographic characteristics between the two groups. Infants in the control group were significantly more likely to receive exchange blood transfusion than infants in the immunoglobulin treatment group, but were significantly less likely to need phototherapy. Conclusion Intravenous immunoglobulin is an effective alternative to exchange transfusion in infants with glucose-6-phosphate dehydrogenase deficiency hemolytic disease of the newborn. It is suggested that intravenous immunoglobulin may be beneficial as a prophylaxis for infants with hyperbilirubinemia.

Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

Full Text Available Aim of our study was to evaluate the beneficial effect of low dose intrathecal morphine on postoperative analgesia, over the use of intravenous patient controlled anesthesia (PCA, in patients undergoing fast track anesthesia during minimally invasive cardiac surgical procedures. A randomized controlled trial was undertaken after approval from local ethical committee. Written informed consent was obtained from 61 patients receiving mitral or tricuspid or both surgical valve repair in minimal invasive technique. Patients were assigned randomly to 2 groups. Group 1 received general anesthesia and intravenous patient controlled analgesia (PCA pump with Piritramide (GA group. Group 2 received a single shot of intrathecal morphine (1.5 μg/kg body weight prior to the administration of general anesthesia (ITM group. Site of puncture was confined to lumbar (L1-2 or L2-3 intrathecal space. The amount of intravenous piritramide used in post anesthesia care unit (PACU and the first postoperative day was defined as primary end point. Secondary end points included: time for tracheal extubation, pain and sedation scores in PACU upto third postoperative day. For statistical analysis Mann-Whitney-U Test and Fishers exact test (SPSS were used. We found that the demand for intravenous opioids in PACU was significantly reduced in ITM group (P <0.001. Pain scores were significantly decreased in ITM group until second postoperative day (P <0.01. There was no time delay for tracheal extubation in ITM group, and sedation scores did not differ in either group. We conclude that low dose single shot intrathecal morphine provides adequate postoperative analgesia, reduces the intravenous opioid consumption during the early postoperative period and does not defer early extubation.

Full Text Available Objective: To compile a comprehensive summary of published human experience with levodopa given intravenously, with a focus on information required by regulatory agencies.Background: While safe intravenous (IV use of levodopa has been documented for over 50 years, regulatory supervision for pharmaceuticals given by a route other than that approved by the U.S. Food and Drug Administration (FDA has become increasingly cautious. If delivering a drug by an alternate route raises the risk of adverse events, an investigational new drug (IND application is required, including a comprehensive review of toxicity data.Methods: Over 200 articles referring to IV levodopa were examined for details of administration, pharmacokinetics, benefit and side effects.Results: We identified 142 original reports describing IVLD use in humans, beginning with psychiatric research in 1959-1960 before the development of peripheral decarboxylase inhibitors. Over 2750 subjects have received IV levodopa, and reported outcomes include parkinsonian signs, sleep variables, hormone levels, hemodynamics, CSF amino acid composition, regional cerebral blood flow, cognition, perception and complex behavior. Mean pharmacokinetic variables were summarized for 49 healthy subjects and 190 with Parkinson’s disease. Side effects were those expected from clinical experience with oral levodopa and dopamine agonists. No articles reported deaths or induction of psychosis.Conclusion: Over 2750 patients have received IV levodopa with a safety profile comparable to that seen with oral administration.

Intravenous phenobarbital (IV-PB) therapy was launched in Japan in October 2008. We retrospectively investigated its efficacy and tolerability in patients with status epilepticus. Forty-three consecutive patients received IV-PB for status epilepticus between June 2009 and April 2011. Among them, 39 patients had underlying diseases, which included acute diseases in 19 patients and chronic conditions in 20 patients. Although 18 patients had been taking antiepileptic drugs (AEDs) before the occurrence of status epilepticus, the blood AED concentrations in 8 patients was below the therapeutic levels. Before the administration of IV-PB, 39 patients were treated with intravenous benzodiazepine, 17 patients were treated with intravenous phenytoin, and 15 patients with intravenous infusion of lidocaine. The initial doses of IV-PB ranged from 125 to 1,250 mg (1.9-20.0 mg/kg). Additional doses of IV-PB were required in 12 patients. Seizures were controlled in 35 patients (81%) after IV-PB administration. Cessation of status epilepticus was attained in 24 patients after the initial dose and in 11 patients after additional doses. There were no serious adverse effects, although respiratory suppression was observed in 3 patients and drug eruption was observed in 1 patient. IV-PB is relatively safe and effective for controlling status epilepticus. If the first dose is not effective, additional doses are required up to the recommended maximum dose.

The goal of this study was to assess risk for CIN after CT Scan during an emergency and to identify risk factors for the patient. Prospective review of all patients admitted to the emergency room (ER) of the Teaching Hospital of Lomé (Togo) during a 2-year period. CIN was defined as an increase in serum creatinine by 0.5 mg/dL from admission after undergoing CT Scan with intravenous contrast. A total of 620 patients underwent a CT Scan in the emergency room using intravenous contrast and 672 patients took the CT Scan without intravenous contrast. Out of the patients who received intravenous contrast for CT Scan, three percent of them developed CIN during their admission. Moreover, upon discharge no patient had continued renal impairment. No patient required dialysis during their admission. The multivariate analysis of all patients who had serial creatinine levels (including those who did not receive any contrast load) shows no increased risk for acute kidney injury associated intravenous contrast (odds ratio = 0.619, p value = 0.886); only diabetes remains independent risk factor of acute kidney injury (odds ratio = 6.26, p value = 0.031)

To investigate the non-inferiority of postoperative single-dose intravenous antimicrobial prophylaxis to multiple-dose intravenous antimicrobial prophylaxis in terms of the incidence of surgical site infections (SSIs) in patients undergoing elective rectal cancer surgery by a prospective randomized study. Patients undergoing elective surgery for rectal cancer were randomized to receive a single intravenous injection of flomoxef (group 1) or five additional doses (group 2) of flomoxef after the surgery. All the patients had received preoperative oral antibiotic prophylaxis (kanamycin and erythromycin) after mechanical cleansing within 24 h prior to surgery, and had received intravenous flomoxef during surgery. A total of 279 patients (including 139 patients in group 1 and 140 in group 2) were enrolled in the study. The incidence of SSIs was 13.7% in group 1 and 13.6% in group 2 (difference [95% confidence interval]: -0.2% [-0.9 to 0.7%]). The incidence of SSIs was not significantly different in patients undergoing elective rectal surgery who were treated using a single dose of postoperative antibiotics compared to those treated using multiple-dose antibiotics when preoperative mechanical and chemical bowel preparations were employed.

Full Text Available The problem of intrauterine infection (IUI is still relevant today. Ineffective treatment of this pathology is associated with physiological decline of the immunity in these patients. We have proposed the additional use of intravenous immunoglobulin for the treatment of pregnant women with IUI. There were examined 75 patients with IUI, which was diagnosed in the II trimester. The I group consisted of 40 individuals who received conventional treatment, the II group was formed from 35 women who additionally received intravenous immunoglobulin. On the background of IUI, pregnancy was characterized by an increased incidence of threatened miscarriage and premature labor, gestosis and placental dysfunction; during delivery, premature rupture of amniotic membrane and fetal distress were more common. These patients had placenta with both ultrasonic and histological signs of infection. Among newborns, there was a significant increase in the incidence of pathology associated with intrauterine infection. Additional use of intravenous immunoglobulin in the treatment of IUI during the II trimester of pregnancy in comparison with conventional therapy leads to a significant reduction in the incidence of both obstetric complications and perinatal pathology.

Dexketoprofen trometamol is a water-soluble salt of the dextrorotatory enantiomer of the nonsteroidal anti-inflammatory drug ketoprofen. The aim of this study was to investigate the effect of intravenous dexketoprofen on postoperative pain. This study was performed on 50 (ASA I-II) patients scheduled for abdominal hysterectomy. Fifty patients were randomized into two equal groups. Patients received saline solution (Group I) or 50 mg intravenous dexketoprofen (Group II) 1 hour (h) before surgery and 8-16 h after surgery. All patients received a standard anesthetic protocol. At the end of surgery, all patients received intravenous (IV) morphine via a PCA (patient- controlled analgesia) device. Pain scores were assessed at 2, 6, 12 and 24 h after surgery. Morphine consumption and adverse effects were noted during the first 24 h after the surgery. The pain scores were significantly lower in the dexketoprofen group compared with the control group (pdexketoprofen group than the control group (p0.05). We conclude that the administration of IV dexketoprofen provided a significant analgesic benefit and decreased the morphine requirements in patients undergoing abdominal hysterectomy.

In the last two decades, the use of erythropoietin for the correction of anemia in hemodialysis patients has been recommended. In Chile, only 10% of hemodialysis patients use erythropoietin, therefore, the correction of iron deficiency must be optimized. To report the effects of intravenous iron without erythropoietin in the management of anemia in hemodialysis patients. Retrospective analysis of 42 patients that received intravenous ferrous sacharate in doses of 100 mg/week during 5 weeks and 100 mg bimonthly during six months. These patients did not receive erythropoietin. Thirty six patients had iron deficiency. Basal ferritin was 137 +/- 22 micrograms/l and increased to 321 +/- 28 micrograms/l after treatment. Packed red cell volume increased from 24 +/- 2% to 29 +/- 3%. No adverse effects were reported. Iron deficiency is frequent in hemodialyzed patients. Intraveineous iron is safe and effective in the treatment of iron deficiency in these patients.

Background. Proton pump inhibitors (PPIs) are currently the most effective agents for acid-related disorders. However, studies show that 25-75% of patients receiving intravenous PPIs had no appropriate justification, indicating high rates of inappropriate prescribing. Objective. To examine the appropriate use of intravenous PPIs in accordance with guidelines and the efficacy of a prescribing awareness intervention at an Asian teaching institution. Setting. Prospective audit in a tertiary hospital in Malaysia. Method. Every 4th intravenous PPI prescription received in the pharmacy was screened against hospital guidelines. Interventions for incorrect indication/dose/duration were performed. Patients' demographic data, medical history and the use of intravenous PPI were collected. Included were all adult inpatients prescribed intravenous PPI. Main Outcome Measure. Proportion of appropriate IV PPI prescriptions. Results. Data for 106 patients were collected. Most patients were male [65(61.3%)], Chinese [50(47.2%)], with mean age ± SD = 60.3 ± 18.0 years. Most intravenous PPI prescriptions were initiated by junior doctors from the surgical [47(44.3%)] and medical [42(39.6%)] departments. Only 50/106(47.2%) patients had upper gastrointestinal endoscopy/surgery performed to verify the source of bleeding. Unexplained abdominal pain [81(76.4%)] was the main driver for prescribing intravenous PPIs empirically, out of which 73(68.9%) were for suspected upper gastrointestinal bleed. Overall, intravenous PPI was found to be inappropriately prescribed in 56(52.8%) patients for indication, dose or duration. Interventions on the use of intravenous PPI were most effective when performed by senior doctors (100%), followed by clinical pharmacists (50%), and inpatient pharmacists (37.5%, p = 0.027). Conclusion. Inappropriate intravenous PPI usage is still prevalent despite the enforcement of hospital guidelines. The promotion of prescribing awareness and evidence-based prescribing

Intravenous levetiracetam (LEV) has been shown to be effective and safe in treating adults with refractory status epilepticus (SE). We sought to investigate the efficacy and safety of intravenous LEV for pediatric patients with refractory SE. We performed a retrospective medical-record review of pediatric patients who were treated with intravenous LEV for refractory SE. Clinical information regarding age, sex, seizure type, and underlying neurological status was collected. We evaluated other anticonvulsants that were used prior to administration of intravenous LEV and assessed loading dose, response to treatment, and any adverse events from intravenous LEV administration. Fourteen patients (8 boys and 6 girls) received intravenous LEV for the treatment of refractory SE. The mean age of the patients was 4.4 ± 5.5 years (range, 4 days to 14.6 years). Ten of the patients were neurologically healthy prior to the refractory SE, and the other 4 had been previously diagnosed with epilepsy. The mean loading dose of intravenous LEV was 26 ± 4.6 mg/kg (range, 20-30 mg/kg). Seizure termination occurred in 6 (43%) of the 14 patients. In particular, 4 (57%) of the 7 patients younger than 2 years showed seizure termination. No immediate adverse events occurred during or after infusions. The current study demonstrated that the adjunctive use of intravenous LEV was effective and well tolerated in pediatric patients with refractory SE, even in patients younger than 2 years. Intravenous LEV should be considered as an effective and safe treatment option for refractory SE in pediatric patients.

Emergency Department (ED) headache patients are commonly treated with neuroleptic antiemetics like metoclopramide. Haloperidol has been shown to be effective for migraine treatment. Our study compared the use of metoclopramide vs. haloperidol to treat ED migraine patients. A prospective, double-blinded, randomized control trial of 64 adults aged 18-50 years with migraine headache and no recognized risks for QT-prolongation. Haloperidol 5 mg or metoclopramide 10 mg was given intravenously after 25 mg diphenhydramine. Pain, nausea, restlessness (akathisia), and sedation were assessed with 100-mm visual analog scales (VAS) at baseline and every 20 min, to a maximum of 80 min. The need for rescue medications, side effects, and subject satisfaction were recorded. QTc intervals were measured prior to and after treatment. Follow-up calls after 48 h assessed satisfaction and recurrent or persistent symptoms. Thirty-one subjects received haloperidol, 33 metoclopramide. The groups were similar on all VAS measurements, side effects, and in their satisfaction with therapy. Pain relief averaged 53 mm VAS over both groups, with equal times to maximum improvement. Subjects receiving haloperidol required rescue medication significantly less often (3% vs. 24%, p haloperidol-treated subjects experiencing more restlessness (43% vs. 10%). Intravenous haloperidol is as safe and effective as metoclopramide for the ED treatment of migraine headaches, with less frequent need for rescue medications. Published by Elsevier Inc.

General anesthetic-induced coma therapy has been recommended for the treatment of refractory status epilepticus (RSE). However, the influence of electroencephalographic (EEG) burst suppression (BS) on outcomes still remains unclear. This study investigated the impact of intravenous anesthetic-induced BS on the prognosis of RSE using a retrospective analysis of all consecutive adult patients who received intravenous anesthetic treatment for RSE at the Seoul National University Hospital between January 2006 and June 2011. Twenty-two of the 111 episodes of RSE were enrolled in this study. Of the 22 RSE patients, 12 (54.5%) were women and 18 (81.4%) exhibited generalized convulsive status epilepticus. Sixteen patients (72.7%) were classified as having acute symptomatic etiology, including three patients with anoxic encephalopathy, and others with remote symptomatic etiology. Only two patients (9.1%) had a favorable Status Epilepticus Severity Score (0-2) at admission. All patients received midazolam (MDZ) as a primary intravenous anesthetic drug for RSE treatment; three (13.6%) received MDZ and propofol, and one (4.5%) received MDZ and pentobarbital. The rates of mortality and poor outcome at discharge were 13.6% (n=3) and 54.5% (n=12), respectively. While BS was achieved in six (27.5%) patients, it was not associated with mortality or poor outcome. Induced BS was associated with prolonged hospital stay in subgroup analysis when excluding anoxic encephalopathy. Our results suggest that induction of BS for treating RSE did not affect mortality or outcome at discharge and may lead to an increased length of hospital stay. Copyright © 2014 Elsevier Ltd.

Directory of Open Access Journals (Sweden)

Marcelo Soares Privado

Full Text Available CONTEXT AND OBJECTIVE: Controversy exists regarding the site of action of fentanyl after epidural injection. The objective of this investigation was to compare the efficacy of epidural and intravenous fentanyl for orthopedic surgery. DESIGN AND SETTING: A randomized double-blind study was performed in Hospital São Paulo. METHODS: During the postoperative period, in the presence of pain, 29 patients were divided into two groups: group 1 (n = 14 received 100 µg of fentanyl epidurally and 2 ml of saline intravenously; group 2 (n = 15 received 5 ml of saline epidurally and 100 µg of fentanyl intravenously. The analgesic supplementation consisted of 40 mg of tenoxicam intravenously and, if necessary, 5 ml of 0.25% bupivacaine epidurally. Pain intensity was evaluated on a numerical scale and plasma concentrations of fentanyl were measured simultaneously. RESULTS: The percentage of patients who required supplementary analgesia with tenoxicam was lower in group 1 (71.4% than in group 2 (100%: 95% confidence interval (CI = 0.001-0.4360 (P = 0.001, Fisher's exact test; relative risk, RR = 0.07. Epidural bupivacaine supplementation was also lower in group 1 (14.3% than in group 2 (53.3%: 95% CI = 0.06-1.05 (P = 0.03, Fisher's exact test; RR = 0.26. There was no difference in pain intensity on the numerical scale. Mean fentanyl plasma concentrations were similar in the two groups. CONCLUSION: Intravenous and epidural fentanyl appear to have similar efficacy for reducing pain according to the numerical scale, but supplementary analgesia was needed less frequently when epidural fentanyl was used.

Full Text Available Background: Among hospitalized patients, indications for the measurement of magnesium levels and treatment of hypomagnesemia with intravenous magnesium are not well defined. Recently, there have been reports of worldwide shortages of intravenous magnesium sulphate. Objective: To examine secular trends in the administration of intravenous magnesium on hospital wards at a tertiary care institution. The secondary objective is to identify factors associated with magnesium use among admitted patients. Methods: Retrospective cross-section review of hospitalized patients at a single Canadian tertiary care center. Utilization of non-parental nutrition intravenous magnesium from 2003 to 2013 stratified by hospital ward was examined. In addition, patient level data from select wards (including medical and surgical services was examined at early and more recent time period (4/2006 versus 4/2013. Results: Among the 248,329 hospitalized patients, intravenous magnesium use increased by 2.86 fold from 2003 to 2013. Not all wards had an increase whereas some had nearly a 10 fold increase in use. In the sample ( n = 769, (adjusting for admission magnesium level, presence of an indication for intravenous magnesium, ward location, comorbidity and demographics intravenous magnesium administration was higher (25.8 % versus 5.5 % in 2013 versus 2006 (OR 13.91 (95 % CI, 6.21–31.17, p < 0.001. Despite this increase in intravenous magnesium administration, <3 % of patients were admitted on oral magnesium in 2006 and 2013. For patients receiving intravenous magnesium only a minority were discharged on oral therapy despite low levels. Conclusions: This center has witnessed a considerable increase in the use of in-hospital intravenous magnesium over the last 6 years that cannot be explained for by medical indications. The risks and benefits of this therapy deserve further study. If this change in practice is representative of other North American hospitals, it may be

Tranexamic acid decreases blood loss in primary total knee arthroplasty, and no related prospective randomized clinical trials have been conducted to evaluate the effectiveness and safety of tranexamic acid in revision total knee arthroplasty. Thus, we conducted this work to evaluate the synergistic effects of intravenous plus intra-articular tranexamic acid on reducing hemoglobin loss compared with intra-articular tranexamic acid alone in revision total knee arthroplasty. This prospective, controlled study randomized 96 patients undergoing revision total knee arthroplasty into two groups: an intravenous plus intra-articular tranexamic acid group (48 patients who received 20 mg/kg intravenous tranexamic acid and 3.0 g intra-articular tranexamic acid); and an intra-articular tranexamic acid alone group (48 patients who received the same intravenous volume of normal saline and 3.0 g intra-articular tranexamic acid). The primary outcome was hemoglobin loss. Secondary outcomes included the volume of drain output, the percentage of patients who received transfusions, the number of units transfused, and thromboembolic events. The baseline data, preoperative hemoglobin, and tourniquet time were similar in both groups. There was significantly less hemoglobin loss in the intravenous plus intra-articular tranexamic acid group compared with the intra-articular tranexamic acid alone group (2.7 ± 0.6 g/dL and 3.7 ± 0.7 g/dL; p tranexamic acid alone group, the intravenous plus intra-articular tranexamic acid group also had significantly less drain output, fewer patients who received transfusions, and fewer units transfused (all p tranexamic acid alone, combined intravenous plus intra-articular tranexamic acid significantly reduced hemoglobin loss and the need for transfusion without an apparent increase in thromboembolic events in patients who underwent revision total knee arthroplasty. © 2018 AABB.

Full Text Available Abstract Background Studies of the efficacy of vitamin C treatment for fatigue have yielded inconsistent results. One of the reasons for this inconsistency could be the difference in delivery routes. Therefore, we planned a clinical trial with intravenous vitamin C administration. Methods We evaluated the effect of intravenous vitamin C on fatigue in office workers. A group of 141 healthy volunteers, aged 20 to 49 years participated in this randomized, double-blind, controlled clinical trial. The trial group received 10 grams of vitamin C with normal saline intravenously, while the placebo group received normal saline only. Since vitamin C is a well-known antioxidant, oxidative stress was measured. Fatigue score, oxidative stress, and plasma vitamin C levels were measured before intervention, and again two hours and one day after intervention. Adverse events were monitored. Results The fatigue scores measured at two hours after intervention and one day after intervention were significantly different between the two groups (p = 0.004; fatigue scores decreased in the vitamin C group after two hours and remained lower for one day. Trial also led to higher plasma vitamin C levels and lower oxidative stress compared to the placebo group (p Conclusion Thus, intravenous vitamin C reduced fatigue at two hours, and the effect persisted for one day. There were no significant differences in adverse events between two groups. High dose intravenous vitamin C proved to be safe and effective against fatigue in this study.

Full Text Available Abstract Background Post-transplant anaemia remains a common problem after kidney transplantation, with an incidence ranging from nearly 80% at day 0 to about 25% at 1 year. It has been associated with poor graft outcome, and recently has also been shown to be associated with increased mortality. Our transplant unit routinely administers oral iron supplements to renal transplant recipients but this is frequently accompanied by side effects, mainly gastrointestinal intolerance. Intravenous iron is frequently administered to dialysis patients and we sought to investigate this mode of administration in transplant recipients after noticing less anaemia in several patients who had received intravenous iron just prior to being called in for transplantation. Methods This study is a single-centre, prospective, open-label, randomised, controlled trial of oral versus intravenous iron supplements in renal transplant recipients and aims to recruit approximately 100 patients over a 12-month period. Patients will be randomised to receive a single dose of 500 mg iron polymaltose (intravenous iron group or 2 ferrous sulphate slow-release tablets daily (oral iron group. The primary outcome is time to normalisation of haemoglobin post-transplant. Prospective power calculations have indicated that a minimum of 48 patients in each group would have to be followed up for 3 months in order to have a 90% probability of detecting a halving of the time to correction of haemoglobin levels to ≥110 g/l in iron-treated patients, assuming an α of 0.05. All eligible adult patients undergoing renal transplantation at the Princess Alexandra Hospital will be offered participation in the trial. Exclusion criteria will include iron overload (transferrin saturation >50% or ferritin >800 μg/l, or previous intolerance of either oral or intravenous iron supplements. Discussion If the trial shows a reduction in the time to correction of anaemia with intravenous iron or less side

Administration of intravenous therapy is a common occurrence within the hospital setting. Routine replacement of administration sets has been advocated to reduce intravenous infusion contamination. If decreasing the frequency of changing intravenous administration sets does not increase infection rates, a change in practice could result in considerable cost savings. The objective of this review was to identify the optimal interval for the routine replacement of intravenous administration sets when infusate or parenteral nutrition (lipid and non-lipid) solutions are administered to people in hospital via central or peripheral venous catheters. We searched The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, CINAHL, EMBASE: all from inception to February 2004; reference lists of identified trials, and bibliographies of published reviews. We also contacted researchers in the field. We did not have a language restriction. We included all randomized or quasi-randomized controlled trials addressing the frequency of replacing intravenous administration sets when parenteral nutrition (lipid and non-lipid containing solutions) or infusions (excluding blood) were administered to people in hospital via a central or peripheral catheter. Two authors assessed all potentially relevant studies. We resolved disagreements between the two authors by discussion with a third author. We collected data for the outcomes; infusate contamination; infusate-related bloodstream infection; catheter contamination; catheter-related bloodstream infection; all-cause bloodstream infection and all-cause mortality. We identified 23 references for review. We excluded eight of these studies; five because they did not fit the inclusion criteria and three because of inadequate data. We extracted data from the remaining 15 references (13 studies) with 4783 participants. We conclude that there is no evidence that changing intravenous administration sets more often than every 96 hours

Many hospitalized patients continue to receive intravenous medications longer than necessary. Earlier conversion from the intravenous to the oral route could increase patient safety and comfort, reduce costs, and facilitate earlier discharge from the hospital without compromising clinical care. We examined the effect of a computer-based intervention to prompt physicians to switch appropriate patients from intravenous to oral medications. This study was performed at Brigham and Women's Hospital, an academic tertiary care hospital at which all medications are ordered online. We targeted 5 medications with equal oral and intravenous bioavailability: fluconazole, levofloxacin, metronidazole, ranitidine, and amiodarone. We used the hospital's computerized order entry system to prompt physicians to convert appropriate intravenous medications to the oral route. We measured the total use of the targeted medications via each route in the 4 months before and after the implementation of the intervention. We also measured the rate at which physicians responded to the intervention when prompted. The average intravenous defined daily dose declined by 11.1% (P =.002) from the preintervention to the postintervention period, while the average oral defined daily dose increased by 3.7% (P =.002). Length of stay, case-mix index, and total drug use at the hospital increased during the study period. The average total monthly use of the intravenous preparation of all of the targeted medications declined in the 4 months after the intervention began, compared with the 4 months before. In 35.6% of 1045 orders for which a prompt was generated, the physician either made a conversion from the intravenous to the oral version or canceled the order altogether. Computer-generated reminders can produce a substantial reduction in excessive use of targeted intravenous medications. As online prescribing becomes more common, this approach can be used to reduce excess use of intravenous medications

Full Text Available Abstract Background The aim of this study was to investigate the analgesic effects of intravenous flurbiprofen axetil for the refractory pain in cancer patients. Methods 2109 patients were screened from the department of medical oncology, the first affiliated hospital of Anhui medical university in China between October of 2007 and October of 2008. Thirty-seven cases of cancer patients who had bad effect from anaesthetic drugs were received administration of intravenous flurbiprofen axetil with dose of 50 mg/5 ml/day. The pain score was evaluated for pre- and post- treatment by Pain Faces Scale criteria, and the side effects were also observed. Results Intravenous flurbiprofen axetil increased the analgesic effects. The total effective rate was 92%. The side effects, such as abdominal pain, alimentary tract bleeding which were found in using NSAIDs or constipation, nausea, vomit, sleepiness which were found in using opioid drugs did not be found. Conclusion Intravenous flurbiprofen axetil could provide better analgesia effects and few side effects to patients with refractory cancer pain. It could also increase analgesia effects when combining with anesthetic drugs in treatment of moderate or severe pain, especially breakthrough pain, and suit to patients who can not take oral drugs for the reason of constipation and psychosomatic symptoms.

Forty children whose mean age was 2.67±0.35 years were examined; thermal injuries accounted for 25.05±1.01% of the total body surface area; of them degrees IIIaIIIb was 19.04±0.85%. A comparison group (n=15 received conventional therapy without taking into account and correcting baseline and current hemostasiological disorders. On day 1, a study group (n=25 had programmed anticoagulant therapy and intravenous laser therapy at different radiation frequencies with a Mustang 20002+ laser therapy apparatus (patent for invention No. 2482894 in addition to the conventional therapy. The laser therapy cycle was 6 to 16 sessions. The investigators estimated and compared the following examined parameters: white blood cell count; leukocytic index of intoxication; plasma average mass molecules at a wavelength of 254 nm; toxogenic granularity of neutrophils; wound exudate discharge time; surgical plasty area; and hospitalization time.Results. The positive laboratory and clinical effects of the performed combined intravenous laser therapy in the combined therapy of burn disease in young children were comparatively shown in the study group patients. The significant decrease in the level of an inflammatory response and endogenous intoxication led to a rapider burn wound cleansing, active epithelization, and reduced surgical plasty volumes.Conclusion. Combined intravenous laser therapy signif icantly exerts antiinflammatory and detoxifying effects in young children with 40% thermal injuries in the acute period of burn disease. Abolishing a systemic inflammatory response by combined intravenous laser therapy initiated early regenerative processes in the burn wound and caused reductions in surgical plasty volumes and hospitalization time, which optimizes ther

High-grade gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs, G3) are aggressive cancers of the digestive system with poor prognosis and survival. Platinum-based chemotherapy (cisplatin/carboplatin + etoposide) is considered the first-line palliative treatment. Etoposide is frequently...... administered intravenously; however, oral etoposide may be used as an alternative. Concerns for oral etoposide include decreased bioavailability, inter- and intra-patient variability and patient compliance. We aimed to evaluate possible differences in progression-free survival (PFS) and overall survival (OS......) in patients treated with oral etoposide compared to etoposide given as infusion.

Intravenous Lipids for Preterm Infants: A Review

Directory of Open Access Journals (Sweden)

Ghassan S. A. Salama

Full Text Available Extremely low birth weight infants (ELBW are born at a time when the fetus is undergoing rapid intrauterine brain and body growth. Continuation of this growth in the first several weeks postnatally during the time these infants are on ventilator support and receiving critical care is often a challenge. These infants are usually highly stressed and at risk for catabolism. Parenteral nutrition is needed in these infants because most cannot meet the majority of their nutritional needs using the enteral route. Despite adoption of a more aggressive approach with amino acid infusions, there still appears to be a reluctance to use early intravenous lipids. This is based on several dogmas that suggest that lipid infusions may be associated with the development or exacerbation of lung disease, displace bilirubin from albumin, exacerbate sepsis, and cause CNS injury and thrombocytopena. Several recent reviews have focused on intravenous nutrition for premature neonate, but very little exists that provides a comprehensive review of intravenous lipid for very low birth and other critically ill neonates. Here, we would like to provide a brief basic overview, of lipid biochemistry and metabolism of lipids, especially as they pertain to the preterm infant, discuss the origin of some of the current clinical practices, and provide a review of the literature, that can be used as a basis for revising clinical care, and provide some clarity in this controversial area, where clinical care is often based more on tradition and dogma than science.

For CT, minor side effects (e.g., nausea, vomiting, pain) following intravenous administration of contrast medium may degrade image quality by causing patient motion or by delaying scanning. The objective of this study was to see if nonionic contrast agents offer advantages in reducing the incidence of such side effects. One hundred five pediatric patients randomly received iohexol (Omnipaque), Iopamidol (Isovue), or diatrizoate sodium (Hypaque). Contrast medium was given in doses of 2 mL/kg body weight (300 mg of iodine per milliliter). The results are presented in the paper

Dynamics of glucose concentration in human organism is an important diagnostic characteristic for it's parameters correlate significantly with the severity of metabolic, vessel and perfusion disorders. 36 patients with stable angina pectoris of II and III functional classes were involved in this study. All of them were men in age range of 45-59 years old. 7 patients hospitalized with acute myocardial infarction (aged from 49 to 59 years old) form the group of compare. Control group (n = 5) was of practically healthy men in comparable age. To all patients intravenous glucose solution (40%) in standard loading dose was injected. Capillary and vein blood samples were withdrawn before, and 5, 60, 120, 180 and 240 minutes after glucose load. At these time points blood pressure and glucose concentration were measured. In prepared blood smears shape, deformability and sizes of erythrocytes, quantity and degree of shear stress resistant erythrocyte aggregates were studied. Received data were approximated by polynomial of high degree to receive concentration function of studied parameters, which first derivative elucidate velocity characteristics of morphofunctional erythrocyte properties during intravenous glucose injection in patients with coronary heart disease and practically healthy persons. Received data show principle differences in dynamics of morphofunctional erythrocyte properties during intravenous glucose injection in patients with coronary heart disease as a possible mechanism of coronary blood flow destabilization.

Intravenous opioids represent a major component in the pathophysiology of postoperative ileus (POI). However, the most appropriate measure and threshold to quantify the association between opioid dose (eg, average daily, cumulative, maximum daily) and POI remains unknown. To evaluate the relationship between opioid dose, POI, and length of stay (LOS) and identify the opioid measure that was most strongly associated with POI. Consecutive patients admitted to a community teaching hospital who underwent elective colorectal surgery by any technique with an enhanced-recovery protocol postoperatively were retrospectively identified. Patients were excluded if they received epidural analgesia, developed a major intraabdominal complication or medical complication, or had a prolonged workup prior to surgery. Intravenous opioid doses were quantified and converted to hydromorphone equivalents. Classification and regression tree (CART) analysis was used to determine the dosing threshold for the opioid measure most associated with POI and define high versus low use of opioids. Risk factors for POI and prolonged LOS were determined through multivariate analysis. The incidence of POI in 279 patients was 8.6%. CART analysis identified a maximum daily intravenous hydromorphone dose of 2 mg or more as the opioid measure most associated with POI. Multivariate analysis revealed maximum daily hydromorphone dose of 2 mg or more (p = 0.034), open surgical technique (p = 0.045), and days of intravenous narcotic therapy (p = 0.003) as significant risk factors for POI. Variables associated with increased LOS were POI (p POI and prolonged LOS, particularly when the maximum hydromorphone dose per day exceeds 2 mg. Clinicians should consider alternative, nonopioid-based pain management options when this occurs.

The objective of this study was to compare the effectiveness of a virtual intravenous simulator with a plastic arm model in teaching intravenous catheter insertion skills to nursing students. We used a randomized controlled quasi-experimental trial design and recruited 65 students who were assigned to the experimental (n = 33) and control (n = 32) groups using the simple random sampling method. The experimental group received intravenous catheterization skills training on the virtual intravenous simulator, and the control group received the same training on a plastic model of a human arm. Data were collected using the personal information form, intravenous catheterization knowledge assessment form, Intravenous Catheterization Skill Test, Self-Confidence and Satisfaction Scale, and Fear Symptoms Scale. In the study, the mean scores in the control group were 20.44 for psychomotor skills, 15.62 for clinical psychomotor skills, 31.78 for self-confidence, and 21.77 for satisfaction. The mean scores in the experimental group were 45.18 for psychomotor skills, 16.28 for clinical psychomotor skills, 34.18 for self-confidence, and 43.89 for satisfaction. The results indicated that psychomotor skills and satisfaction scores were higher in the experimental group, while the clinical psychomotor skills and self-confidence scores were similar in both groups. More students in the control group reported experiencing symptoms such as cold and sweaty hands, significant restlessness, and tense muscles than those in the experimental group.

Intravenous access in prehospital emergency care allows for early administration of medication and extended measures such as anaesthesia. Cannulation may, however, be difficult, and failure and resulting delay in treatment and transport may have negative effects on the patient. Therefore, our study aims to perform a concise assessment of the difficulties of prehospital venous cannulation. We analysed 23 candidate predictor variables on peripheral venous cannulations in terms of cannulation failure and exceedance of a 2 min time threshold. Multivariate logistic regression models were fitted for variables of predictive value (P0.6) of their respective receiver operating characteristic curve. A total of 762 intravenous cannulations were enroled. In all, 22% of punctures failed on the first attempt and 13% of punctures exceeded 2 min. Model selection yielded a three-factor model (vein visibility without tourniquet, vein palpability with tourniquet and insufficient ambient lighting) of fair accuracy for the prediction of puncture failure (AUC=0.76) and a structurally congruent model of four factors (failure model factors plus vein visibility with tourniquet) for the exceedance of the 2 min threshold (AUC=0.80). Our study offers a simple assessment to identify cases of difficult intravenous access in prehospital emergency care. Of the numerous factors subjectively perceived as possibly exerting influences on cannulation, only the universal - not exclusive to emergency care - factors of lighting, vein visibility and palpability proved to be valid predictors of cannulation failure and exceedance of a 2 min threshold.

The determinations of concentration were done by the way of the reverse-phase high-performance liquid chromatography (HPLC with ultraviolet (UV detection. Statistic processing of the received data was carried out using the Wilcoxon criterion.Results of research. There was received the statistically significant increase of clindamycin concentration in CSF of patients in a day after combined (intrathecal + intravenous administration of preparation comparing with an intravenous administration.Conclusions. 1. Intrathecal administration of 150 mg. of clindamycin with 8 mg. of dexamethasone is safe.2. Intrathecal administration of 150 mg. of clindamycin with 8 mg. of dexamethasone in combination with an intravenous administration of preparation leads to statistically significant increase of clindamycin concentration in CSF at least during a day after injection.3. Intrathecal administration of clindamycin with dexamethasone in offered doses can be recommended for treatment of meningoencephalitises that caused by microorganisms susceptible to clindamycin.4. If the therapy of toxoplasmic meningoencephalitis was started with an intravenous prescription of clindamycin it is recommended an additional treatment with an intrathecal administration of clindamycin with dexamethasone in offered doses to increase efficiency by creating an effective concentration of preparation in the nidus of infection.5. Intrathecal methods of therapy must be used by the specialists of

Bioelectrical impedance (BIA) is often used to measure body fluid spaces and thereby body composition. However, in acute animal studies, we found that impedance was driven by the saline content of intravenous (IV) fluids and not by the volume. The aim of the study was to investigate the effect of 3 different fluids acutely administered on the change in impedance, specifically resistance (R). Nine healthy adults participated in 3 treatment (0.9% saline, 5% dextrose, and a mixture of 0.3% saline + 3.3% dextrose) experiments on nonconsecutive days. They all received 1 L of one of the treatments intravenously over a 1-hour period. Repeated BIA measurements were performed prior to IV infusion and then every 5 minutes for the 1-hour infusion period, plus 3 more measurements up to 15 minutes after the completion of the infusion. The change in R in the 0.9% saline infusion experiment was significantly lower than that of the glucose and mixture treatment ( P < .001). Bioelectrical impedance spectroscopy and BIA measure salt rather than the volume changes over the infusion period. Hence, in patients receiving IV fluids, BIA of any kind (single frequency or multifrequency) cannot be used to measure body fluid spaces or body composition.

Background Numerous neuroprotective drugs have failed to show benefit in the treatment of acute ischemic stroke, making the search for new treatments imperative. Uric acid is an endogenous antioxidant making it a drug candidate to improve stroke outcomes. Aim To report the effects of uric acid therapy in stroke patients receiving intravenous thrombolysis and mechanical thrombectomy. Methods Forty-five patients with proximal vessel occlusions enrolled in the URICO-ICTUS trial received intravenous recombinant tissue plasminogen activator within 4.5 h after stroke onset and randomized to intravenous 1000 mg uric acid or placebo (NCT00860366). These patients also received mechanical thrombectomy because a brain computed tomogaphy angiography confirmed the lack of proximal recanalization at the end of systemic thrombolysis. The primary outcome was good functional outcome at 90 days (modified Rankin Score 0-2). Safety outcomes included mortality, symptomatic intracerebral bleeding, and gout attacks. Results The rate of successful revascularization was >80% in the uric acid and the placebo groups but good functional outcome was observed in 16 out of 24 (67%) patients treated with uric acid and 10 out of 21 (48%) treated with placebo (adjusted Odds Ratio, 6.12 (95% CI 1.08-34.56)). Mortality was observed in two out of 24 (8.3%) patients treated with uric acid and one out of 21 (4.8%) treated with placebo (adjusted Odds Ratio, 3.74 (95% CI 0.06-226.29)). Symptomatic cerebral bleeding and gout attacks were similar in both groups. Conclusions Uric acid therapy was safe and improved stroke outcomes in stroke patients receiving intravenous thrombolysis followed by thrombectomy. Validation of this simple strategy in a larger trial is urgent.

Full Text Available Background. Traditional mistletoe therapy in cancer patients involves subcutaneous applications of Viscum album L. preparations, with doses slowly increasing based on patient responses. Intravenous infusion of high doses may improve therapeutic outcomes and is becoming more common. Little is known about the safety of this “off-label” application of mistletoe. Methods. An observational study was performed within the Network Oncology. Treatment with intravenous mistletoe applications is described. The frequency of adverse drug reactions (ADRs to intravenous mistletoe applications was calculated and compared to ADR data from a study on subcutaneous applications. Results. Of 475 cancer patients who received intravenous infusions of Helixor, Abnoba viscum, or Iscador mistletoe preparations, 22 patients (4.6% reported 32 ADRs of mild (59.4% or moderate severity (40.6%. No serious ADRs occurred. ADRs were more frequently reported to i.v. mistletoe administered alone (4.3%, versus prior to chemotherapy (1.6%. ADR frequency differed with respect to preparation type, with Iscador preparations showing a higher relative frequency, compared to Abnoba viscum and Helixor. Overall, patients were almost two times less likely to experience an ADR to intravenous compared to subcutaneous application of mistletoe. Conclusion. Intravenous mistletoe therapy was found to be safe and prospective studies for efficacy are recommended.

Full Text Available Background Indomethacin and ibuprofen are the drugs of choice for closure of patent ductus arteriosus (PDA in preterm infants. However, intravenous preparations are of limited availability in Indonesia. Circumstantial evidence has shown that intravenous paracetamol may be an alternative therapy for PDA closure in premature infants. Objective To evaluate the effect of intravenous paracetamol on PDA closure in preterm infants. Methods A before-and-after study was conducted between May and August 2014 in Cipto Mangunkusumo General Hospital, Jakarta in preterm infants with hemodynamically significant PDAs, as established by echocardiography using the following criteria: duct diameter >1.4 mm/kg, left atrium to aorta ratio >1.4, and mean velocity in the left pulmonary artery >0.42 m/s or mean diastolic velocity in the left pulmonary artery >0.2 m/s. Subjects, aged 2 and 7 days, received intravenous paracetamol (15 mg/kg every six hours for 3 days. Paired T-test was used to compare pre-intervention PDA diameter to those assessed at 24 hours after the intervention and at 14 days of life. Results Twenty-nine subjects had a mean gestational age of 30.8 weeks and mean birth weight of 1,347 grams. Nineteen (65.5% patients had closed PDAs at the day 14 evaluation, 1 experienced PDA reopening, and 9 had failed PDA closure. No liver toxicity was identified. Mean duct diameters before, 24 hours after the intervention, and at 14 days of life were 3.0, 0.9, and 0.6 mm, respectively (P<0.0001. Conclusion Intravenous paracetamol seems to be reasonably effective for PDA closure in preterm infants.

To compare the ABZ and its metabolites concentration in cyst tissue of hepatic alveolar echinococcosis administered by different routes, forty male Wistar rats receiving albendazole nanoparticles from tail vein and portal vein were divided into two groups, the concentration of ABZ and its metabolites ABZSO, ABZSO2, in the cyst tissue, were analyzed by HPLC at 2, 4, 8, 24, 36 h after administration. The parent drug and its metabolites were detected in plasm and the cyst tissue after portal cannulation and intravenous administration. The last results were the concentration of ABZ in the portal cannulation group was higher than in the intravenous group at every time point (p < 0.05). Compared to the intravenous group, the portal cannulation administration of ABZ led to a lower plasm concentration of ABZ. The concentration of ABZ and the active ABZSO were significantly higher in the portal cannulation group than that of the intravenous group. Copyright © 2015 Elsevier Inc. All rights reserved.

Identification of Risk Factors for Intravenous Infiltration among Hospitalized Children: A Retrospective Study.

Directory of Open Access Journals (Sweden)

Soon Mi Park

Full Text Available This retrospective study was aimed to identify risk factors of intravenous (IV infiltration for hospitalized children. The participants were 1,174 children admitted to a general hospital, who received peripheral intravenous injection therapy at least once, and had complete records. Data were analyzed with frequency and percentage or mean and standard deviation were calculated, and odds ratio (OR from univariate and multiple logistic regressions. The number and % of infiltrations were 92 and 7.8%, respectively. IV infiltration risk factors were lower limb (OR = 1.72, phenytoin (OR = 11.03, 10% dextrose (OR = 6.55, steroids (OR = 6.21, vancomycin (OR = 4.10, high-concentration electrolytes (OR = 3.49, and ampicillin/sulbactam combination (OR = 3.37. Nurses working at children's hospitals should consider the risk of IV infiltration for children receiving IV infusion therapy and make a preventive effort to identify IV infiltration in high-risk children at an early stage.

Lacosamide is an antiepilepsy drug approved by the Food and Drug Administration for patients aged 17 years and older for partial-onset seizures as monotherapy or adjunctive therapy. We reviewed the use of intravenous lacosamide in children aged less than 17 years with status epilepticus. Children who received at least one dose of intravenous lacosamide for status epilepticus at our tertiary care children's hospital from December 2011 to March 2014 were studied. Status epilepticus was defined as continuous seizure activity for longer than 20 minutes or two or more recurrent seizures without regaining baseline level of awareness. Efficacy was defined as seizure freedom or more than 50% reduction of seizures within 24 hours of administering lacosamide. Nine children with a mean age of 5.7 years (range: three months to 16 years) were included. The mean initial or loading dose was 8.7 mg/kg, with seven of nine patients receiving a dose of 10 mg/kg. The average total amount of intravenous lacosamide administered within the initial 24 hours was 13.8 mg/kg. Lacosamide was found to be efficacious in seven of nine (77.8%) patients. Four patients (44.4%) became seizure free. Two patients continued to have status epilepticus within 24 hours of lacosamide administration. Bradycardia was observed in one patient. In children with status epilepticus, intravenous lacosamide was efficacious in 78% of the patients and 44% become seizure free. In addition, no significant adverse reactions were observed. An appropriate safe, effective initial, or loading dose may be 10 mg/kg. Copyright © 2016 Elsevier Inc. All rights reserved.

To estimate whether treatment with intravenous nitroglycerin for uterine relaxation increases the chance of successful external cephalic version. Two double-blind, randomized clinical trials were undertaken: one in nulliparous women and a second in multiparous women. Women presenting for external cephalic version at term were eligible to participate. The primary outcome was immediate success of external cephalic version. Other outcomes were presentation at delivery, cesarean delivery rate, and side effects and complications. Sample size calculations were based on a 100% increase in success of external cephalic version with a one-sided analysis and alpha=0.05 (80% power). In total, 126 women were recruited-82 in the nulliparous trial and 44 in the multiparous trial. Seven patients did not have external cephalic version before delivery but were included in the analysis of success of external cephalic version. One patient was lost to follow-up. The external cephalic version success rate for nulliparous patients was 24% (10 of 42) in patients who received nitroglycerin compared with 8% (3 of 40) in those who receive placebo (P=.04, one-sided Fisher exact test, odds ratio 3.85, lower bound 1.22). In multiparous patients, the external cephalic version success rate did not differ significantly between groups: 44% (10 of 23) in the nitroglycerin group compared with 43% (9 of 21) in the placebo group (P=.60). Treatment with intravenous nitroglycerin increased the rate of successful external cephalic version in nulliparous, but not in multiparous, women. Treatment with intravenous nitroglycerin appeared to be safe, but our numbers were too small to rule out rare serious adverse effects. I.

New guidelines for "rapid or ultrarapid" intravenous rehydration are being developed in different emergency departments. These new guidelines propose a faster administration of fluids and electrolytes than in traditional protocols. However, there is still insufficient evidence to establish a standard protocol. Our objective was to determine the effects of an outpatient rapid intravenous rehydration regimen based on the administration of 0.9% saline + 2.5% dextrose, at a rate of 20 mL/kg per hour for 2 hours, in children with mild-to-moderate isonatremic dehydration resulting from acute gastroenteritis. We performed a 2-institution, prospective, observational, descriptive study. Eighty-three patients were included in the study. All patients underwent a first evaluation, including physical examination, laboratory tests, and assessment of clinical degree of dehydration. After this initial evaluation, all children received our intravenous rehydration regimen. A second evaluation including the same items as in the first one was made after in all the children. Intravenous rehydration was successful in 69 patients (83.1%). It failed in 14 patients (16.8%), who required hospitalization because of persistent vomiting in 9 patients and poor general appearance in 5 patients. After intravenous rehydration, we observed a statistically significant decrease in the levels of ketonemia and uremia and in the Gorelick scale score. However, no significant changes were observed in sodium, chloride, potassium, and osmolarity values. We conclude that, in children with mild-to-moderate dehydration, the administration of 20 mL/kg per hour for 2 hours of 0.9% saline solution + 2.5% glucose improved clinical scores and may be used as an alternative and safe way for intravenous rehydration.

Tonsillectomy is the oldest and most frequently performed surgical procedure practiced by ear, nose, and throat physicians. In this study, our aim was to compare the analgesic effects of peritonsillar, rectal, as well as intravenous infiltration of ketamine and intravenous tramadol hydrochloride infiltration for postoperative pain relief and sedation after tonsillectomy in children. This randomized controlled study evaluated the effects of peritonsillar, intravenous, and rectal infiltration of ketamine in children undergoing adenotonsillectomy. One hundred twenty children who were categorized under American Society of Anesthesiologists classes I to II were randomized to 4 groups of 30 members each. Group 1 received intravenous (IV) ketamine (0.5 mg/kg), group 2 received rectal ketamine (0.5 mg/kg), group 3 received local peritonsillar ketamine (2 mg/kg), and the control group received IV tramadol hydrochloride infiltration (2 mg/kg). Children's Hospital of Eastern Ontario Pain Scale scores and Wilson sedation scale were recorded at minutes 1, 15, 30, 60 as well as hours 2, 12, and 24 postoperatively. The patients were interviewed on the day after the surgery to assess the postoperative pain and sedation. All the routes of infiltration of ketamine were as effective as those of tramadol hydrochloride (P > 0.05). A statistically significant difference was observed between IV infiltrations and all groups during the assessments at hours 6 and 24. The analgesic efficacy of IV ketamine was found especially higher at hours 6 and 24 (P(6) = 0.045, P(24) = 0.011). Perioperative, low-dose IV, rectal, or peritonsillar ketamine infiltration provides efficient pain relief without any adverse effects in children who would undergo adenotonsillectomy.

Full Text Available Background: Proton pump inhibitors (PPIs are currently the most effective agents for acid related disorders. However, studies show that 25-75% of patients receiving intravenous Pantoprazole had no appropriate justification, indicating high rate of inappropriate prescribing in hospitals. The aim of this study is to examine the appropriate use of intravenous Pantoprazole in accordance with guidelines at Shahid Sadoughi hospital.Methods: From January to April 2015, sample of 100 prescriptions who received Intravenous (IV Pantoprazole were collected with observational and sectional model in Intensive care unit (ICU and general wards of “Shahid Sadoughi” Hospital of Yazd, Iran. Clinical data from patient records are obtained and these data were mapped to establish clinical criteria and appropriate use of Intravenous Pantoprazole.Results: The majority (63% of Intravenous Pantoprazole prescriptions were deemed inappropriate in terms of either indication for use, dose or duration of therapy. 51.5% of the patients were above 55 years old. Endoscopy did not performed in most of the Non UGIB (Non upper gastrointestinal bleeding cases. Most Intravenous Pantoprazole prescriptions were ordered by junior doctors (Intern, and again this group were significantly less likely to prescribe the drug for appropriate reasons when compared with more experienced clinicians.Conclusion: This study suggests that the majority of IV PPI prescriptions in our hospital are inappropriate. Awareness of the result of this article through medical staff could result in more judicious use of intravenous pantoprazole and dose optimization. Physicians and pharmacists can work together to create solutions to inappropriate drug use.

Although the diagnostic utility of thallium-201 myocardial imaging after dipyridamole infusion is well established, the intravenous form of the drug is not yet commercially available in North America. Fifty patients referred for coronary angiography were prospectively studied. Within a 2 week period, each patient underwent cardiac catheterization and thallium-201 myocardial imaging after both oral and intravenous dipyridamole administration. For the oral protocol, patients were randomly assigned to treatment with either 200 or 400 mg of dipyridamole in tablet form. Coronary artery stenoses of 70% or greater were considered significant. For the 25 patients who received a 200 mg oral dose of dipyridamole, the scintigraphic study showed perfusion defects in 65% of patients with significant coronary artery disease after the oral dose and in 85% of patients after the intravenous dose. For the 25 patients who received a 400 mg oral dose, the sensitivity of the scintigram was 84% after the oral dose and 79% after the intravenous dose. Except for headache and nausea, side effects were less severe and less frequent with oral (either 200 or 400 mg) than with intravenous dipyridamole. Because of the delayed and variable absorption of dipyridamole tablets, the oral studies required a longer period of medical supervision (45 to 60 minutes), and aminophylline was empirically administered after completion of the first set of thallium-201 images. It is concluded from this study that thallium-201 myocardial imaging after coronary vasodilation with a 400 mg oral dose of dipyridamole is a safe, widely available and reliable alternative for the evaluation of coronary artery disease in patients unable to achieve an adequate exercise level on stress testing

Iron deficiency is a common nutritional deficiency amongst women of childbearing age. Peri-partum iron deficiency anaemia (IDA) is associated with significant maternal, fetal and infant morbidity. Current options for treatment are limited: these include oral iron supplementation, which can be ineffective and poorly tolerated, and red blood cell transfusions, which carry an inherent risk and should be avoided. Ferric carboxymaltose is a new treatment option that may be better tolerated.The study was designed to assess the safety and efficacy of iron deficiency anaemia (IDA) correction with intravenous ferric carboxymaltose in pregnant women with mild, moderate and severe anaemia in the second and third trimester. Prospective observational study; 65 anaemic pregnant women received ferric carboxymaltose up to 15 mg/kg between 24 and 40 weeks of pregnancy (median 35 weeks gestational age, SD 3.6). Treatment effectiveness was assessed by repeat haemoglobin (Hb) measurements and patient report of well-being in the postpartum period. Safety was assessed by analysis of adverse drug reactions and fetal heart rate monitoring during the infusion. Intravenous ferric carboxymaltose infusion significantly increased Hb values (p anaemia in pregnancy.

Cardiorespiratory adverse effects are often observed in patients undergoing upper gastrointestinal endoscopy with sedation. In this study, we examined hemodynamics, oxygen saturation and memory during upper gastrointestinal endoscopy under sedation with intravenous midazolam. Eight healthy outpatients without any obvious complications received intravenous midazolam 5 mg for sedation for upper gastrointestinal endoscopy. Blood pressure, heart rate and percutaneous arterial oxygen saturation (SpO2) were measured before, during and after endoscopy. After the arousal by intravenous flumazenil, we inquired the patients about the level of memory during the endoscopy. Blood pressure decreased significantly two minutes after midazolam administration, but increased significantly after the insertion of an endoscope which was not different from the control value. Heart rate increased significantly one and three minutes after the insertion of the endoscope. SpO2 decreased significantly after midazolam administration and stayed at around 95%. No patients remembered the procedure. Sedation with intravenous midazolam during upper gastrointestinal endoscopy is useful to control the cardiovascular responses, and to obtain amnesia. However, a decrease in SpO2 should be watched carefully.

Bernese (Ganz) periacetabular osteotomy is associated with significant blood loss and the need for perioperative transfusion. Tranexamic acid decreases blood loss and minimizes transfusion rates in total joint arthroplasty. However, no reports have described its use in patients undergoing Bernese periacetabular osteotomy. This study reports the use of intravenous tranexamic acid in these patients. The study included 137 patients (150 hips) who underwent isolated periacetabular osteotomy at a single institution between 2003 and 2014. Of these, 68 patients (75 hips) received intravenous tranexamic acid 1 g at the time of incision and 1 g at the time of closure. A group of 69 patients (75 hips) served as control subjects who underwent periacetabular osteotomy without administration of intravenous tranexamic acid. Thromboembolic disease was defined as deep venous thrombosis or pulmonary embolism occurring within 6 weeks of surgery. Outcomes measured included transfusion requirements, pre- and postoperative hemoglobin values, operative times, and thromboembolic disease rates. Aspirin was used as the thromboembolic prophylactic regimen in 95% of patients. The rate of allogeneic transfusion was 0 in the tranexamic acid group compared with 21% in the control group (P=.0001). No significant difference was found in the autologous cell salvage requirement (.96 vs 1.01; P=.43) or the thromboembolic disease rate between the tranexamic acid group and the control group (2.67% vs 1.33%; P=.31). The use of intravenous tranexamic acid led to a decreased transfusion requirement with no increased risk of thromboembolic disease in this contemporary cohort of patients undergoing periacetabular osteotomy.

Full Text Available Insertion of central venous catheter is an accepted method for hemodynamic monitor-ring, drug and fluid administration, intravenous access, hemodialysis and applying cardiac pace-maker in hospitalized patients. This procedure can be associated with severe complications. The aim of this article is to provide a practical approach to prevent catheter malposition in states that the guide wire will not pass freely.During central venous insertion in internal jugular vein using modified seldinger technique, when after venous insertion, the passage of the guide wire shows difficulties and don’t pass freely, insertion of an intravenous cannula over the wire and re-insertion of the wire can help to prevent malposition of the wire and the catheter. Use of an intravenous cannula over the guide, in situations that the guide wire cannot pass freely among the needle inserted in internal jugular vein, and re-insertion of the guide can probably prevent or reduce the tissue or vascular trauma and the associated complica-tions. This simple maneuver can be helpful in difficult cases especially in cardiac surgery patients who receive high dose heparin and it is necessary to avoid traumatize-tion of carotid artery.

Orthopedic surgeons are becoming more involved in the care of patients with septic arthritis and bursitis caused by yeast species. This case report involves a middle-aged immunocompromised female who developed a Candida glabrata septic olecranon bursitis that developed after she received a corticosteroid injection in the olecranon bursa for presumed aseptic bursitis. Candida (Torulopsis) glabrata is the second most frequently isolated Candida species from the bloodstream in the United States. Increased use of fluconazole and other azole antifungal agents as a prophylactic treatment for recurrent Candida albicans infections in immunocompromised individuals is one reason why there appears to be increased resistance of C. glabrata and other nonalbicans Candida (NAC) species to fluconazole. In this patient, this infection was treated with surgery (bursectomy) and intravenous caspofungin, an echinocandin. This rare infectious etiology coupled with this intravenous antifungal treatment makes this case novel among cases of olecranon bursitis caused by yeasts.

Full Text Available The prevalence of pressure ulcers of the foot is a major health care problem in frail elderly patients. A pressure sore dramatically increases the cost of medical and nursing care, and effective treatment has always been an essential nursing concern. Management options for pressure ulcers include local wound care; surgical repair and, more recently, topical application of growth factors.The main goal of this study was to examine the effects of intravenous treatment of Semelil (ANGIPARSTM, a new herbal extract in patients with severe, noninfected pressure ulcers of the foot.As a randomized clinical trial, 18 patients with pressure ulcers were recruited from Vali-e-Asr hospital, Medical Sciences/ University of Tehran, Iran. Nine patients received intravenous Semelil (ANGIPARSTM besides to conventional therapy and nine received only conventional treatment.At the baseline, the treatment and control groups did not differ across demographic variables, clinical characteristics, and functional measures. The mean surface areas of the ulcers were reduced 43.2 ± 57.4 cm2 (80.3% and 2.8± 6.2 cm² (6.3% in the treatment and control groups, respectively (p=0.000. The average reduction in pressure ulcer area at four weeks was statistically and clinically greater in the treatment group than in the control group So, intravenous Semelil (ANGIPARSTM can be recommended as an effective treatment for patients with severe pressure ulcers.

Org 25435 is a new water-soluble alpha-amino acid ester intravenous anaesthetic which proved satisfactory in animal studies. This study aimed to assess the safety, tolerability and efficacy of Org 25435 and to obtain preliminary pharmacodynamic and pharmacokinetic data. In the Short Infusion study 8 healthy male volunteers received a 1 minute infusion of 0.25, 0.5, 1.0, or 2.0 mg/kg (n = 2 per group); a further 10 received 3.0 mg/kg (n = 5) or 4.0 mg/kg (n = 5). Following preliminary pharmacokinetic modelling 7 subjects received a titrated 30 minute Target Controlled Infusion (TCI), total dose 5.8-20 mg/kg. Within the Short Infusion study, all subjects were successfully anaesthetised at 3 and 4 mg/kg. Within the TCI study 5 subjects were anaesthetised and 2 showed signs of sedation. Org 25435 caused hypotension and tachycardia at doses over 2 mg/kg. Recovery from anaesthesia after a 30 min administration of Org 25435 was slow (13.7 min). Pharmacokinetic modelling suggests that the context sensitive half-time of Org 25435 is slightly shorter than that of propofol in infusions up to 20 minutes but progressively longer thereafter. Org 25435 is an effective intravenous anaesthetic in man at doses of 3 and 4 mg/kg given over 1 minute. Longer infusions can maintain anaesthesia but recovery is slow. Hypotension and tachycardia during anaesthesia and slow recovery of consciousness after cessation of drug administration suggest this compound has no advantages over currently available intravenous anaesthetics.

Unruptured Cerebral Aneurysm Detected after Intravenous Tissue Plasminogen Activator for Stroke

Directory of Open Access Journals (Sweden)

Yukihiro Yoneda

2009-06-01

Full Text Available Therapeutic guidelines of intravenous thrombolysis with tissue plasminogen activator (tPA for hyperacute ischemic stroke are very strict. Because of potential higher risk of bleeding complications, the presence of unruptured cerebral aneurysm is a contraindication for systemic thrombolysis with tPA. According to the standard CT criteria, a 66-year-old woman who suddenly developed aphasia and hemiparesis received intravenous tPA within 3 h after ischemic stroke. Magnetic resonance angiography during tPA infusion was performed and the presence of a small unruptured cerebral aneurysm was suspected at the anterior communicating artery. Delayed cerebral angiography confirmed an aneurysm with a size of 7 mm. The patient did not experience any adverse complications associated with the aneurysm. Clinical experiences of this kind of accidental off-label thrombolysis may contribute to modify the current rigid tPA guidelines for stroke.

We assess the success rate of emergency physicians in placing peripheral intravenous catheters in difficult-access patients who were unsuccessfully cannulated by emergency nurses. A technique using real-time ultrasonographic guidance by 2 physicians was compared with traditional approaches using palpation and landmark guidance. This was a prospective, systematically allocated study of all patients requiring intravenous access who presented to 2 university hospitals between October 2003 and March 2004. Inclusion criterion was the inability of any available nurse to obtain intravenous access after at least 3 attempts on a subgroup of patients who had a history of difficult intravenous access because of obesity, history of intravenous drug abuse, or chronic medical problems. Exclusion criterion was the need for central venous access. Patients presenting on odd days were allocated to the ultrasonographic-guided group, and those presenting on even days were allocated to the traditional-approach group. Endpoints were successful cannulation, number of sticks, time, and patient satisfaction. Sixty patients were enrolled, 39 on odd days and 21 on even days. Success rate was greater for the ultrasonographic group (97%) versus control (33%), difference in proportions of 64% (95% confidence interval [CI] 39% to 71%). The ultrasonographic group required less overall time (13 minutes versus 30 minutes, for a difference of 17 [95% CI 0.8 to 25.6]), less time to successful cannulation from first percutaneous puncture (4 minutes versus 15 minutes, for a difference of 11 [95% CI 8.2 to 19.4]), and fewer percutaneous punctures (1.7 versus 3.7, for a difference of 2.0 [95% CI 1.27 to 2.82]) and had greater patient satisfaction (8.7 versus 5.7, for a difference of 3.0 [95% CI 1.82 to 4.29]) than the traditional landmark approach. Ultrasonographic-guided peripheral intravenous access is more successful than traditional "blind" techniques, requires less time, decreases the number of

Full Text Available Background: Alpha 2 -adrenergic agonists have synergistic action with local anesthetics and may prolong the duration of sensory, motor blockade and postoperative analgesia obtained with spinal anesthesia. Aim: The objectives of this study are to compare and evaluate the efficacy of intravenous dexmedetomidine premedication with clonidine and placebo on spinal blockade duration, postoperative analgesia and sedation in patients undergoing surgery under bupivacaine intrathecal block. Materials and Methods: In this prospective, randomized, double-blind placebo-controlled study, 75 patients of the American Society of Anesthesiologists status I or II, scheduled for orthopedic lower limb surgery under spinal anesthesia, were randomly allocated into three groups of 25 each. Group DE received dexmedetomidine 0.5 μgkg−1 , group CL received clonidine 1.0 μgkg−1 and placebo group PL received 10 ml of normal saline intravenously before subarachnoid anesthesia with 15 mg of 0.5% hyperbaric bupivacaine. Onset time and regression times of sensory and motor blockade, the maximum upper level of sensory blockade were recorded. Duration of postoperative analgesia and sedation scores along with side effects were also recorded. Data was analyzed using analysis of variance or Chi-square test, and the value of P < 0.05 was considered statistically significant. Results: The sensory block level was higher with dexmedetomidine (T4 ± 1 than clonidine (T6 ± 1 or placebo (T6 ± 2. Dexmedetomidine also increased the time (243.35 ± 56.82 min to first postoperative analgesic request compared with clonidine (190.93 ± 42.38 min, P < 0.0001 and placebo (140.75 ± 28.52 min, P < 0.0001. The maximum Ramsay sedation score was greater in the dexmedetomidine group than other two groups (P < 0.0001. Conclusion: Premedication with intravenous dexmedetomidine is better than intravenous clonidine to provide intraoperative sedation and postoperative analgesia during bupivacaine

Dexmedetomidine also increased the time (243.35 ± 56.82 min) to first postoperative analgesic request compared with clonidine (190.93 ± 42.38 min, P < 0.0001) and placebo (140.75 ± 28.52 min, P < 0.0001). The maximum Ramsay sedation score was greater in the dexmedetomidine group than other two groups (P < 0.0001). Conclusion: Premedication with intravenous dexmedetomidine is better than intravenous clonidine to provide intraoperative sedation and postoperative analgesia during bupivacaine spinal anesthesia

AIM: To determine whether the timing of buscopan administration during double-contrast barium enema examination (DCBE) affects diagnostic quality. MATERIALS AND METHODS: In a prospective setting, 100 consecutive adult out-patients referred for DCBE received 20 mg buscopan (hyoscine-N-butylbromide) intravenously, either before infusion of barium suspension (Group A) or after barium infusion and gas insufflation (Group B). A subjective assessment of ease of contrast medium infusion was made at the time of examination and the films subsequently analysed by two radiologists unaware of the mode of relaxant administration, who noted the quality of mucosal coating and made subjective and objective measurements of segmental distension. RESULTS: There was no significant difference in screening times, infusion difficulty or colonic contrast medium coating between the two groups. Subjective assessment of distension of the caecum, ascending colon, transverse colon and rectum were not significantly different. Patients receiving intravenous relaxant after barium and gas infusion had less subjective descending (P = 0.05) and sigmoid (P = 0.04) colon distension, but there was no significant difference with respect to maximal bowel diameter in any of the segments measured. CONCLUSION: The timing of intravenous administration during DCBE is likely to have no significant effect on the diagnostic quality of the study. Elson, E.M. (2000)

Introduction Proximal cervical internal carotid artery stenosis greater than 50% merits revascularization to mitigate the risk of stroke recurrence among large-vessel anterior circulation strokes undergoing mechanical thrombectomy. Carotid artery stenting necessitates the use of antiplatelets, and there is a theoretical increased risk of hemorrhagic transformation given that such patients may already have received intravenous thrombolytics and have a significant infarct burden. We investigate the outcomes of large-vessel anterior circulation stroke patients treated with intravenous thrombolytics receiving same-day carotid stenting or selective angioplasty compared to no carotid intervention. Materials and methods The study cohort was obtained from the National (Nationwide) Inpatient Sample database between 2006 and 2014, using International Statistical Classification of Diseases, ninth revision discharge diagnosis and procedure codes. A total of 11,825 patients with large-vessel anterior circulation stroke treated with intravenous thrombolytic and mechanical thrombectomy on the same day were identified. The study population was subdivided into three subgroups: no carotid intervention, same-day carotid angioplasty without carotid stenting, and same-day carotid stenting. Outcomes were assessed with respect to mortality, significant disability at discharge, hemorrhagic transformation, and requirement of percutaneous endoscopic gastronomy tube placement, prolonged mechanical ventilation, or craniotomy. Results This study found no statistically significant difference in patient outcomes in those treated with concurrent carotid stenting compared to no carotid intervention in terms of morbidity or mortality. Conclusions If indicated, it is reasonable to consider concurrent carotid stenting and/or angioplasty for large-vessel anterior circulation stroke patients treated with mechanical thrombectomy who also receive intravenous thrombolytics.

The aim of this study was to compare the efficacy and safety of 3 nonsteroidal anti-inflammatory drugs-intravenous tenoxicam, lornoxicam, and dexketoprofen trometamol-for the treatment of patients with renal colic. We conducted a prospective double-blind randomized trial of consecutive adult patients who presented to the emergency department with a chief complaint of acute flank pain and had a clinical diagnosis of suspected acute renal colic. Patients were randomly allocated to receive an intravenous bolus of tenoxicam, lornoxicam, or dexketoprofen trometamol in a blinded fashion. Primary outcome measure of the study was visual analog scale (VAS) score difference at 30 minutes. Secondary outcome measures were VAS scores at 5, 15, and 120 minutes as well as rescue analgesic need at 30 minutes and adverse events during the follow-up period. A total of 445 patients were screened, and 123 patients were enrolled in the study. The mean age was 36 ± 10 years. The mean reduction in VAS pain scores at 30 minutes was 42 ± 26 mm for tenoxicam, 57 ± 23 mm for lornoxicam, and 52 ± 25 mm for dexketoprofen (P = .047). Lornoxicam demonstrated the fastest rate of VAS score reduction over the first 30 minutes. The mean reduction values in VAS pain scores at 5, 15, and 120 minutes were similar among the 3 groups. Rescue analgesics at 30 minutes were required by 16 patients (39%) receiving tenoxicam, 10 patients (24%) receiving lornoxicam, and 8 patients (19%) receiving dexketoprofen (P = .121). No serious adverse events were observed. Intravenous tenoxicam, lornoxicam, and dexketoprofen are all effective in the treatment of renal colic, although lornoxicam appears to reduce VAS pain scores with the fastest rate in this comparison.

Background Requirements for allogeneic red cell transfusion after total lower limb arthroplasty are still high (20–50%), and post-operative intravenous iron has been shown to reduce transfusion requirements for this surgery. We performed a cost analysis to ascertain whether this alternative is also likely to be cost-effective. Materials and methods Data from 182 matched-pairs of total lower limb arthroplasty patients, managed with a restrictive transfusion protocol and without (control group) or with post-operative intravenous iron (iron group), were retrospectively reviewed. Acquisition and administration costs of iron (iron sucrose or ferric carboxymaltose) and allogeneic red cell concentrates, haemoglobin measurements, and prolonged stay in hospital were used for blood management cost analysis. Results Patients in the iron group received 600 mg intravenous iron, without clinically relevant incidents, and had a lower allogeneic transfusion rate (11.5% vs 26.4% for the iron and control groups, respectively; p=0.001). The reduction in transfusion rate was more pronounced in anaemic patients (17% vs 40%; p=0.015) than in non-anaemic ones (9.6% vs 21.2%; p=0.011). There were no differences with respect to post-operative infection rate. Patients receiving allogeneic transfusion stayed in hospital longer (+1.9 days [95% CI: 1.2–2.6]). As intravenous iron reduces the allogeneic transfusion rate, both iron formulations were cost-neutral in the different cost scenarios (−25.5 to 62.1 €/patient for iron sucrose, and −51.1 to 64.4 €/patient for ferric carboxymaltose). Discussion In patients presenting with or without pre-operative anaemia, post-operative intravenous iron after total lower limb arthroplasty seems to be safe and is associated with reduced transfusion rates, without incremental costs. For anaemic patients, its efficacy could be increased by associating some other blood-saving method. PMID:24120595

Informed consent for the administration of an intravenous contrast agent: importance and determinants of patient refusal

We proposed to determine the proportion of patients who refuse to undergo intravenous contrast administration and the factors that influence their refusal. Our series consisted of 442 patients who were supposed to undergo imaging studies involving the intravenous injection of an iodine contrast. In a personal interview, the patients were issued a questionnaire specifically designed for this study. The following parameters were recorded: sex, age, inpatient or outpatient status, medical history available, person who informed them about the procedure, person signing the informed consent (patient or other) , highest academic degree, attitude toward receiving the information and degree of concern after reading and signing the consent form. In our series 8.6% of the patients (95% confidence interval: 6-11.2) refused to sign the informed consent form. In addition, there were a number of patients who delayed the procedure or hindered the daily work schedule by some other means. When the relationship between each of the variables studied and refusal to sign the consent form was assessed, significant associations were observed between the latter and the academic level of the patient, his or her degree of concern and having received the information from a trained person. There was also a nearly significant trend toward the association between refusal and the patient's background. Relatively few patients refuse to sign the informed consent to receive intravenous contrast administration but this negative decision interferes with the health care practice. It is possible to identify certain correctable factors that influence the patient in this respect. (Author) 13 refs

Patients with chronic obstructive pulmonary disease are usually excluded from intravenous dipyridamole thallium-201 testing. We developed a nurse-administered protocol to screen and pretreat patients so they could be safely tested. We prospectively screened patients referred for intravenous dipyridamole thallium testing and retrospectively reviewed a comparison group of patients who had undergone intravenous dipyridamole testing before our bronchospasm protocol. We studied 492 consecutive patients referred for intravenous dipyridamole thallium testing, separating those with complete data (n = 451) into two groups: group A (n = 72), patients assessed to be at risk for intravenous dipyridamole-induced bronchospasm who received our bronchospasm treatment protocol; and group B (n = 379), patients assessed to be free of risk, who did not receive our bronchospasm protocol. Group C (n = 89) was a retrospective comparison group of patients who had undergone intravenous dipyridamole testing before initiation of the protocol. Patients were considered at risk for an adverse event if any of the following were present: peak flow 400 ml after bronchodilator treatment, wheezing audible with stethoscope, history of chronic obstructive pulmonary disease or asthma or dyspnea on exertion at less than four blocks, or resting respiratory rate >18 breaths/min. The test was considered contraindicated if resting oxygen saturation was respiratory rate stethoscope but without marked respiratory distress), (2) marked events (severe bronchospasm or severe ischemia defined as wheezing audible with or without stethoscope, respiratory rate >20 breaths/min or increased by 10 from pretest evaluation, oxygen desaturation to respiratory rate with decreased mental status], respiratory arrest, chest pain, horizontal ST-segment depression > or =1 mm on the electrocardiogram in any lead, symptomatic hypotension), or (3) other intravenous dipyridamole-induced side effects (persistent headache, dizziness

Ten healthy volunteers received three standard Bier's blocks. Prilocaine 0.5%, 40 ml was injected at a solution temperature of 0 degrees C, 22 degrees C or 37 degrees C. Recordings were made of sensory block, motor block, intravenous pressure, limb temperature and pain on injection. There were no differences between the three treatments in the rate of development or in the quality of block but there was a significant difference in the comfort of injection. Cold solutions caused most, and warm solutions least discomfort.

To compare the efficacy of intravenous ondansetron or dexamethasone compared with intravenous fluid therapy alone in children presenting to the emergency department with refractory vomiting from viral gastritis who had failed attempts at oral hydration. This double-blind, randomized, controlled trial was performed in a tertiary care pediatric emergency department. Children aged 6 months to 12 years presenting with more than three episodes of vomiting in the past 24 hours, mild/moderate dehydration, and failed oral hydration were included. Patients with other medical causes were excluded. Subjects were randomized to dexamethasone 1 mg/kg (15 mg maximum), ondansetron 0.15 mg/kg, or placebo (normal saline [NS], 10 mL). All subjects also received intravenous NS at 10-20 mL/kg/hr. Oral fluid tolerance was evaluated at two and four hours. Those not tolerating oral fluids at four hours were admitted. Discharged patients were evaluated at 24 and 72 hours for vomiting and repeat health care visits. The primary study outcome was hospitalization rates between the groups. Data were analyzed using chi-square test, Kruskal-Wallis test, Mantel-Haenszel test, and analysis of variance, with p hydration than NS-treated patients (29 [67.4%]; relative risk, 1.28; 95% confidence interval = 1.02 to 1.68). There were no differences in number of mean episodes of vomiting or repeat visits to health care at 24 and 72 hours in the ondansetron, dexamethasone, or NS groups. In children with dehydration secondary to vomiting from acute viral gastritis, ondansetron with intravenous rehydration improves tolerance of oral fluids after two hours and reduces the hospital admission rate when compared with intravenous rehydration with or without dexamethasone.

Full Text Available Salivary gland enlargement following the administration of iodine is an extremely rare event, and the pathophysiology of iodine-induced sialadenitis is not yet fully known. The onset of symptoms can start within a few minutes to five days after contrast administration. The course of iodine-induced sialadenitis is extremely benign, and rapid resolution of symptoms is expected without treatment. We report the case of a 59-year-old white female who noted mildly painful swelling involving the right side of her face within five days of receiving intravenous iodine-containing contrast. A diagnosis of iodine-related sialadenitis was made. She was given 20 mg of decadron intravenously, with prompt resolution of the swelling within a few hours.

Severe malaria is a medical emergency associated with high mortality. Adequate treatment requires initial parenteral therapy for fast parasite clearance followed by longer acting oral antimalarial drugs for cure and prevention of recrudescence. In a randomized controlled clinical trial, we evaluated the 42-day parasitological outcomes of severe malaria treatment with intravenous artesunate (AS) or intravenous quinine (QNN) followed by oral artemisinin based combination therapy (ACT) in children living in a high malaria transmission setting in Eastern Uganda. We enrolled 300 participants and all were included in the intention to treat analysis. Baseline characteristics were similar across treatment arms. The median and interquartile range for number of days from baseline to parasite clearance was significantly lower among participants who received intravenous AS (2 (1-2) vs 3 (2-3), P malaria symptoms. In this high transmission setting, we observed adequate initial treatment outcomes followed by very high rates of malaria re-infection post severe malaria treatment. The impact of recurrent antimalarial treatment on the long term efficacy of antimalarial regimens needs to be investigated and surveillance mechanisms for resistance markers established since recurrent malaria infections are likely to be exposed to sub-therapeutic drug concentrations. More strategies for prevention of recurrent malaria infections in the most at risk populations are needed. The study was registered with the Pan African Clinical Trial Registry ( PACTR201110000321348 ).

The use of intravenous (IV) or topical tranexamic acid (TXA) in total hip arthroplasty has been proven to be effective and safe in total hip arthroplasty. However, which of these two administration routes is better has not been determined. The combined administration of TXA has been used in total knee arthroplasty with satisfactory results. We hypothesized that combined application of TXA may be the most effective way without increased rate of thrombotic events such as deep vein thrombosis (DVT) and pulmonary embolisms (PE) in patients subjected to primary total hip replacement (THA). A meta-analysis was conducted to compare the efficacy and safety of the combined use of tranexamic acid (TXA) relative to topical or intravenous (IV) use alone for treatment of primary THA. The outcomes included total blood loss, postoperative hemoglobin decline, transfusion rates, and the incidence rates of deep vein thrombosis (DVT) and pulmonary embolisms (PE). We searched electronic databases including PubMed, EMBASE, the Cochrane Library, Web of Science, the Chinese Biomedical Literature database, the CNKI database, and Wanfang Data until September 2016. The references of the included articles were also checked for additional potentially relevant studies. There were no language restrictions for the search. The data of the included studies were analyzed using RevMan 5.3 software. Seven studies met the inclusion criteria, encompassing a total of 1762 patients. Our meta-analysis demonstrated that total blood loss, postoperative hemoglobin decline, and transfusion rates were significantly lower for patients that received the combined treatment compared to patients that received either topical or intravenous administration of TXA. No statistical differences were found in the incidence of deep venous thrombosis (DVT) or pulmonary embolism (PE). The group that received the combined treatment had lower total blood loss, postoperative hemoglobin decline, and transfusion rates without an

The objectives of this study were to evaluate the effects of intravenous acetate Ringer's solution, with or without dextrose, on diarrheic calves with either experimentally induced or spontaneous diarrhea. In the experimental model, diarrhea was induced in nine healthy calves by administering cold milk (below 4°C) twice a day for 2 days. The calves were randomly assigned to the isotonic saline (ISS), acetated Ringer's (AR) or acetated Ringer's with 5% dextrose (ARD) groups, with three calves assigned to each group. The calves received 80 ml/kg of their designated solution, at a flow rate of 20 ml/kg/hr. Infusion of ISS, AR and ARD were all found to be safe and effective in increasing plasma volume. Intravenous (IV) infusion of ISS resulted in the acidification secondary to dilution, while AR and ARD infusion inhibited acidification. In addition, prevention of catabolism was observed only with IV infusion of ARD. Sixteen calves with spontaneous diarrhea were enrolled in the clinical study. The calves were randomly assigned to the AR or ARD groups, with eight calves being assigned to each group. The calves received 100 ml/kg of their designated solution, at a flow rate of 25 ml/kg/hr. Intravenous infusion of AR and ARD was found to be effective in increasing plasma volume and inhibiting acidification. Only infusion of ARD prevented catabolism, but it also led to hyperglycemia. Our results suggest that a solution containing dextrose may be beneficial for wasting diarrheic calves.

To determine the efficacy of heparinized saline administered as intermittent flush on functional duration of the peripheral intravenous catheter (PIVC) in neonates. Randomized, double-blind and placebo-controlled trial. Neonatal intensive care unit of a teaching hospital. Term and preterm neonates born at >32 weeks of gestation who required PIVC only for intermittent administration of antibiotics. Eligible neonates were randomized to receive 1 ml of either heparinized saline (10 U ml(-1)) (n=60) or normal saline (n=60) every 12 h before and after intravenous antibiotics. Functional duration of first peripheral intravenous catheter. A total of 120 neonates were randomized to two groups of 60 neonates each. The mean (s.d.) of age of babies in case and control group was 5.7 (2.5) days and 4.6 (3.1) days, respectively. The average weight of babies in both the groups was 2.1 kg. Mean functional duration of first catheter was more in heparinized saline group, mean (s.d.) of 71.68 h  (27.3) as compared with 57.7 h (23.6) in normal saline group (P<0.005). The mean (95% confidence interval) difference in functional duration in the two groups was 13.9 h (4.7-23.15). Mean duration of patency for any catheter was also significantly more in heparinized saline group than control group. Heparinized saline flush increases the functional duration of peripheral intravenous catheter.

Haemodynamically significant patent ductus arteriosus is a significant cause of morbidity and mortality in pre-term infants. This retrospective study was conducted to investigate the usefulness of lower-dose paracetamol for the treatment of patent ductus arteriosus in pre-term infants. A total of 13 pre-term infants who received intravenous paracetamol because of contrindications or side effects to oral ibuprofen were retrospectively enrolled. In the first patient, the dose regimen was 15 mg/kg/dose, every 6 hours. As the patient developed significant elevation in transaminase levels, the dose was decreased to 10 mg/kg/dose, every 8 hours in the following 12 patients. Echocardiographic examination was conducted daily. In case of closure, it was repeated after 2 days and when needed thereafter in terms of reopening. A total of 13 patients received intravenous paracetamol. Median gestational age was 29 weeks ranging from 24 to 31 weeks and birth weight was 950 g ranging from 470 to 1390 g. The median postnatal age at the first intravenous paracetamol dose was 3 days ranging from 2 to 9 days. In 10 of the 13 patients (76.9%), patent ductus arteriosus was closed at the median 2nd day of intravenous paracetamol ranging from 1 to 4 days. When the patient who developed hepatotoxicity was eliminated, the closure rate was found to be 83.3% (10/12). Intravenous paracetamol may be a useful treatment option for the treatment of patent ductus arteriosus in pre-term infants with contrindication to ibuprofen. In our experience, lower-dose paracetamol is effective in closing the patent ductus arteriosus in 83.3% of the cases.

To compare the intravenous boluses and intravenous continuous infusion of tranexamic acid (TXA) to reduce postoperative bleeding in cyanotic congenital heart disease surgeries. Study Design:Single-blinded randomised clinical trial. Place and Duration of Study:Anaesthesia Department, The Aga Khan University Hospital, Karachi, from July 2016 to April 2017. Methodology:Sixty patients of cyanotic congenital heart disease, undergoing either palliative or corrective surgery involving cardiopulmonary bypass (CPB), were recruited. These 60 patients were divided randomly into two groups. The infusion group received intravenous infusion of TXA at 5 mg/kg/hour while the bolus group received three intravenous boluses of 10 mg/kg after induction, after going to bypass and after protamine reversal. Data was collected through predesigned proforma. There were two primary outcomes: postoperative bleeding in the first 24 hours, and chest closure time. Results:Postoperative bleeding was 13.94 (10.27-20.18) ml/kg in the first 24 hours in infusion group and 15.05 (9.04-23.50) ml/kg in the bolus group. Chest closure time was 38.5 (25-45) in infusion group and 30 (20-46.25) minutes in the bolus group. There was no statistically significant and clinical difference between both groups regarding postoperative bleeding in the first 24 hours and chest closure time. Conclusion:These infusion and bolus groups had comparable postoperative bleeding and chest closure time. (author)

Orthostatic stability with intravenous levodopa

Directory of Open Access Journals (Sweden)

2015-08-01

Full Text Available Intravenous levodopa has been used in a multitude of research studies due to its more predictable pharmacokinetics compared to the oral form, which is used frequently as a treatment for Parkinson’s disease (PD. Levodopa is the precursor for dopamine, and intravenous dopamine would strongly affect vascular tone, but peripheral decarboxylase inhibitors are intended to block such effects. Pulse and blood pressure, with orthostatic changes, were recorded before and after intravenous levodopa or placebo—after oral carbidopa—in 13 adults with a chronic tic disorder and 16 tic-free adult control subjects. Levodopa caused no statistically or clinically significant changes in blood pressure or pulse. These data add to previous data that support the safety of i.v. levodopa when given with adequate peripheral inhibition of DOPA decarboxylase.

El-Kersh, Karim; Ruf, Kathryn M; Smith, J Shaun

There is no standard protocol for intravenous treprostinil dose escalation. In most cases, slow up-titration is performed in the outpatient setting. However, rapid up-titration in an inpatient setting is an alternative that provides opportunity for aggressive treatment of common side effects experienced during dose escalation. In this study, we describe our experience with inpatient rapid up-titration of intravenous treprostinil. This was a single-center, retrospective study in which we reviewed the data of subjects with pulmonary arterial hypertension treated at our center who underwent inpatient rapid up-titration of intravenous treprostinil. Our treprostinil dose escalation protocol included initiation at 2 ng·kg·min with subsequent up-titration by 1 ng·kg·min every 6 to 8 hours as tolerated by side effects. A total of 16 subjects were identified. Thirteen subjects were treprostinil naive (naive group), and 3 subjects were receiving subcutaneous treprostinil but were hospitalized for further intravenous up-titration of treprostinil dose (nonnaive group). In the naive group, the median maximum dose achieved was 20 ng·kg·min with an interquartile range (IQR) of 20-23 ng·kg·min. The median up-titration interval was 6 days (IQR: 4-9). In the nonnaive group, the median maximum dose achieved was 20 ng·kg·min (range: 17-30). The median up-titration interval was 8.5 days (range: 1.5-11). Overall, the median maximum dose achieved was 20 ng·kg·min (IQR: 20-23.5), and the median up-titration interval was 6 days (IQR: 4.6-9.25), with no reported significant adverse hemodynamic events. In patients with pulmonary arterial hypertension, rapid inpatient titration of intravenous treprostinil is safe and tolerable.

The objective of this study was to evaluate the postoperative analgesic effect of a preemptive, single-dose intravenous dexketoprofen administration in patients undergoing lumbar microdiscectomy. A total of 50 ASA I-II patients candidate to laminectomy were included in this study. They were divided in two groups. Patients in Group A were given 50 mg (2 mL) dexketoprofen and those in Group K 2 mL normal saline intravenously by a blinded anesthesia physician, 10 minutes before the start of intervention. All cases underwent general anesthesia. All patients received postoperative patient-controlled analgesia with tramadol. The VAS scores 1, 4, 8, 16 and 24 hours following the operation, sedation and patient satisfaction scores and tramadol consumption were evaluated. VAS scores recorded during the first 8 postoperative hours and total tramadol amounts were lower, and the patient satisfaction scores higher, in patients given dexketoprofen than control group. Sedation scores and side effects were similar in both groups. Single-dose preemptive intravenous dexketoprofen provides effective analgesia especially in the first 8 postoperative hours, reducing tramadol use.

Full Text Available Objective: To study the effect of buprenorphine transdermal patch combined with patientcontrolled intravenous analgesia on the serum pain-related biochemical indexes in elderly patients with intertrochanteric fracture. Methods: A total of 92 elderly patients with intertrochanteric fracture who received surgical treatment in the hospital between August 2014 and January 2017 were collected and divided into control group (n=46 and observation group (n=46 according to the random number table method. The control group received patient-controlled intravenous analgesia, and the observation group received buprenorphine transdermal patch combined with patient-controlled intravenous analgesia. Differences in serum levels of inflammatory factors, oxidative stress indexes and pain mediators of two groups of patients were measured before and 24h after surgery. Results: Differences in serum levels of inflammatory factors, oxidative stress indexes and pain mediators were not statistically significant between the two groups before surgery; 24 h after surgery, serum IL- 1β, IL-6, IL-8, TNF-α, MDA, SP, PGE2, 5-HT, HA and NPY levels of both groups of patients increased significantly while SOD, TAC and CAT levels decreased significantly, and serum IL-1β, IL-6, IL-8, TNF-α, MDA, SP, PGE2, 5-HT, HA and NPY levels of observation group were lower than those of control group while SOD, TAC and CAT levels were higher than those of control group. Conclusion: Buprenorphine transdermal patch combined with patient-controlled intravenous analgesia can effectively inhibit the expression of pain-related indexes and relieve early postoperative pain intensity in elderly patients with intertrochanteric fracture.

We attempt in this study to evaluate the effect of intravenous ironsaccharate (i.v. Sach) on the erythropoietin (EPO) requirements during theinitial phase of replacement therapy with recombinant human erythropoietin(r-HuEPO) in adult chronic hemodialysis (HD) patients. We evaluated 96 studypatients who completed 12 weeks of treatment with EPO. There were 69 (72%)males and 27 (28%) females with a mean age of 44+-10 years (range 24 to 74years). The patients were initiated on EPO at 50 units/kg body weightsubcutaneously post-dialysis two to three times weekly. Intravenous iron wasadministered to maintain the ferritin levels and transferrin saturation ratiowithin normal range. There were 36 (37.5%) patients who received i.v. Sach atdoses of 100 mg at the end of dialysis two or three times per week during thewhole study period (total dose 2400-3600 mg). Of the 96 study patients, 91(94.8%) responded to the EPO. The mean hemoglobin (Hb) at entry to the studywas 72+-84 g/L (range 52-88 g/L). There was significant increase of the meanHb to 108+-10 g/L (range 70-120 grams/L) at the end of study (P 0.2and ferritin 0.2 and ferritin >100ng/ml. There were 19 patients in group I (13 received i.v. Sach), 26 in groupII (16 received i.v. Sach) and 44 in group III (seven received i.v. Sach).There was a group of seven patients who had TSAT 100ng/ml, however, none received i.v. sach and they were not included in thestratification. There was no significant difference in the mean Hb betweenpatients who received and those who did not receive i.v. Sach in thesub-groups studied. However, there was a significant decrease in the meanweekly dose of EPO in the patients who received i.v. Sach. We conclude thatroutine use of i.v. iron supplementation in chronic HD patients receivingrecombinant EPO may be beneficial in the initial phase of treatment inattaining the target Hb with lower doses of EPO, regardless of the status ofthe iron indices.

Full Text Available Background and Purpose: Multiple system atrophy with predominant cerebellar ataxia is a disabling neurologic disease. However, effective management has not yet been established. We conducted a short-term, open-label preliminary study to assess the benefits of intravenous amantadine treatment in patients with probable multiple system atrophy with predominant cerebellar ataxia. Methods: Twenty patients (10 male, 10 female with probable multiple system atrophy with predominant cerebellar ataxia received 400 mg of amantadine by intravenous per day for 5 days. Ataxia severity was evaluated by the International Cooperative Ataxia Rating Scale before and after intravenous amantadine therapy and all subjects reported subjective improvement after intravenous amantadine treatment using a patient global impression scale. We analyzed the total and subscale scores by the ataxia scale and patient global impression scale. Results: The mean age was 57.4 years (range: 47–72 and the mean disease duration was 30.8 months (range: 11–79. The ataxia severity significantly decreased after intravenous amantadine therapy from 42.5 to 37.3 (p < 0.001. The mean patient global impression scale for improvement was 2.9 and there were no side effects of intravenous amantadine treatment observed. When we assessed responders, the duration of intravenous amantadine effect was more than 1 month in 4 subjects of 7 responders. Conclusions: Our findings suggest that intravenous amantadine treatment can be a safe management option in cerebellar ataxia, although the mechanism is unclear. Thus, further double-blind, long-term studies with a larger sample size are needed.

This research has focused on the birthing experience of first-time mothers who received the narcotic analgesic combination of Pethidine and Hydroxyzine during the first stage of labour. A qualitative research methodology was used to collect data. Unstructured interviews were held with first-time mothers to obtain accounts of their experience of childbirth. These narrations were audio-taped while the participants were still being cared for in the postnatal ward of the hospital where delivery took place. Nine interviews were conducted with first-time mothers who gave birth normally vaginally after a normal pregnancy and who received a narcotic analgesic in the first stage of labour. The transcribed interviews were analyzed using Tesch's method of descriptive analysis (in Creswell, 1994:115). Four themes with sub-themes emerged from the analysis. The participants reported on the physical experience of labour and described experiencing a lot of pain for which analgesics were given. They also described how these drugs dulled the pain but made them sleepy and unable to cooperate with the midwives. They described their emotional experiences, which included joy and happiness as well as anxiety, anger and despondence. They also reported that they were not sufficiently informed about labour and child-birth. In the last theme they described the methods they used to help them cope with labour including distracting techniques, leaning on a supportive person or praying. Guidelines to help midwives overcome these problems were developed.

Infliximab pharmacokinetic studies have been performed in patients receiving chronic infliximab therapy. In these patients, infliximab antidrug antibodies (ADAs) increase infliximab clearance and decrease serum levels and drug efficacy. This study analyzed the pharmacokinetic effect of infliximab ADAs in healthy subjects receiving a single dose of intravenous infliximab. Data were obtained from a single-blind, parallel-group, single-dose study of healthy subjects receiving 5 mg/kg of intravenous SB2 (infliximab biosimilar), EU-sourced Remicade (EU-IFX) or US-sourced Remicade (US-IFX). Serum infliximab was measured at 1, 2, 3, 6, 12, 24, 48, and 72 h and at 5, 7, 14, 21, 28, 42, 56, and 70 days after administration. ADAs were measured pre-dose and at 29 and 71 days. Data from the first ten subjects randomized to each treatment arm were utilized for this study. A two-compartment model of the serum infliximab vs. time curve was developed using nonlinear regression. At 10 weeks, 11 subjects (37%) developed ADAs. ADAs were detected in four subjects after SB2, one subject after EU-IFX, and six subjects after US-IFX infusion. Of these, neutralizing antibodies occurred in one subject after SB2, in no subjects after EU-IFX, and in three subjects after US-IFX infusion. Infliximab clearance was increased in subjects with ADAs vs. those without ADAs (12.89 ± 2.69 vs. 9.90 ± 1.74 ml/h; p ADAs (282.4 ± 56.4 vs. 343.3 ± 61.9 h; p ADAs are common in healthy subjects after a single intravenous dose of infliximab and result in faster infliximab clearance, shorter elimination time, and lower serum infliximab levels. These data confirm that ADAs are common with biologic therapy and significantly impact the efficacy of these drugs.

[Peripheral intravenous catheter-related phlebitis].

van der Sar-van der Brugge, Simone; Posthuma, E F M Ward

2011-01-01

Phlebitis is a very common complication of the use of intravenous catheters. Two patients with an i.v. catheter complicated by thrombophlebitis are described. Patient A was immunocompromised due to chronic lymphatic leukaemia and developed septic thrombophlebitis with positive blood cultures for S. Aureus. Patient B was being treated with flucloxacillin because of an S. Aureus infection and developed chemical phlebitis. Septic phlebitis is rare, but potentially serious. Chemical or mechanical types of thrombophlebitis are usually less severe, but happen very frequently. Risk factors include: female sex, previous episode of phlebitis, insertion at (ventral) forearm, emergency placement and administration of antibiotics. Until recently, routine replacement of peripheral intravenous catheters after 72-96 h was recommended, but randomised controlled trials have not shown any benefit of this routine. A recent Cochrane Review recommends replacement of peripheral intravenous catheters when clinically indicated only.

Bone and joint infection in adults arises most commonly as a complication of joint replacement surgery, fracture fixation and diabetic foot infection. The associated morbidity can be devastating to patients and costs the National Health Service an estimated £20,000 to £40,000 per patient. Current standard of care in most UK centres includes a prolonged course (4-6 weeks) of intravenous antibiotics supported, if available, by an outpatient parenteral antibiotic therapy service. Intravenous therapy carries with it substantial risks and inconvenience to patients, and the antibiotic-related costs are approximately ten times that of oral therapy. Despite this, there is no evidence to suggest that oral therapy results in inferior outcomes. We hypothesise that, by selecting oral agents with high bioavailability, good tissue penetration and activity against the known or likely pathogens, key outcomes in patients managed primarily with oral therapy are non-inferior to those in patients treated by intravenous therapy. The OVIVA trial is a parallel group, randomised (1:1), un-blinded, non-inferiority trial conducted in thirty hospitals across the UK. Eligible participants are adults (>18 years) with a clinical syndrome consistent with a bone, joint or metalware-associated infection who have received ≤7 days of intravenous antibiotic therapy from the date of definitive surgery (or the start of planned curative therapy in patients treated without surgical intervention). Participants are randomised to receive either oral or intravenous antibiotics, selected by a specialist infection physician, for the first 6 weeks of therapy. The primary outcome measure is definite treatment failure within one year of randomisation, as assessed by a blinded endpoint committee, according to pre-defined microbiological, histological and clinical criteria. Enrolling 1,050 subjects will provide 90 % power to demonstrate non-inferiority, defined as less than 7.5 % absolute increase in treatment

Full Text Available Gregory J Dale,1 Stephanie Phillips,2 Gregory L Falk3 1Westmead Hospital Clinical School, The University of Sydney, 2Sydney Adventist Hospital Clinical School, The University of Sydney, 3Concord Clinical School, The University of Sydney, Sydney, Australia Abstract: This study aimed to determine if intravenous lidocaine infusion reduces postoperative pain intensity following laparoscopic fundoplication surgery and to also validate the safety of intravenous lidocaine at the dose tested. This was an equally randomized, double-blind, placebo-controlled, parallel-group, single center trial. Adult patients undergoing laparoscopic fundoplication were recruited. The intervention group received 1 mg/kg intravenous lidocaine bolus prior to induction of anesthesia, then an intravenous infusion at 2 mg/kg/h for 24 hours. The primary outcome was pain, measured using a numeric rating scale for 30 hours postoperatively. Secondary outcomes were nausea and vomiting, opioid requirements, adverse events, serum lidocaine concentration, and length of hospital stay. The study was terminated after an interim analysis of 24 patients showed evidence of futility. There was no difference in postoperative pain scores (lidocaine versus control, mean ± standard deviation at rest (2.0 ± 2.7 vs 2.1 ± 2.4, P=0.286 or with movement (2.0 ± 2.6 vs 2.6 ± 2.7, P=0.487. Three adverse events occurred in the lidocaine group (25% of patients. Intravenous lidocaine did not provide clinically significant analgesia to patients undergoing laparoscopic fundoplication. The serum lidocaine concentration of patients who experienced adverse events were within the therapeutic range. This trial cannot confirm the safety of intravenous lidocaine at the dose tested.

Purpose The incidence of pain induced withdrawal movement following intravenous injection of rocuronium is high. This randomized, double-blind, placebo-controlled study was designed to evaluate the effect of pretreatment of remifentanil on the withdrawal movements due to intravenous injection of rocuronium during anesthetic induction. Materials and Methods Ninety adult female patients undergoing thyroidectomy were randomly allocated to three groups. Each patient intravenously received one of three solutions of equal volume (4 mL): normal saline (Group I, n = 30), 0.5 µg/kg remifentanil (Group II, n = 30) or 1 µg/kg remifentanil (Group III, n = 30). Thirty seconds after remifentanil administration, anesthesia was induced with 5 mg/kg IV thiopental. Twenty seconds after thiopental injection, 0.6 mg/kg IV rocuronium was administered (injection rate of 0.5 mL/sec) and patients' withdrawal movements were assessed. Mean arterial pressure (MAP) and heart rate were assessed on arrival in the operation room, before the tracheal intubation and immediately, 1 and 2 min after the tracheal intubation. Results The incidence of withdrawal movements was significantly lower in both of the remifentanil groups (3 and 0% in Group II and III, respectively) than in the saline group (70%). Remifentanil attenuated the increase of heart rate and MAP immediately and 1 min after the tracheal intubation. Conclusion The pretreatment with 0.5 and 1.0 µg/kg remifentanil of bolus doses prevented the withdrawal movements caused by rocuronium injection, and effectively blunted cardiovascular activation following tracheal intubation.

A perioperative intravenous lidocaine infusion has been reported to decrease postoperative pain. The goal of this study was to evaluate the effectiveness of intravenous lidocaine in reducing postoperative pain for laparoscopic colectomy patients. Fifty-five patients scheduled for an elective laparoscopic colectomy were randomly assigned to 2 groups. Group L received an intravenous bolus injection of lidocaine 1.5 mg/kg before intubation, followed by 2 mg/kg/h continuous infusion during the operation. Group C received the same dosage of saline at the same time. Postoperative pain was assessed at 2, 4, 8, 12, 24, and 48 hours after surgery by using the visual analog scale (VAS). Fentanyl consumption by patient-controlled plus investigator-controlled rescue administration and the total number of button pushes were measured at 2, 4, 8, 12, 24, and 48 hours after surgery. In addition, C-reactive protein (CRP) levels were checked on the operation day and postoperative days 1, 2, 3, and 5. VAS scores were significantly lower in group L than group C until 24 hours after surgery. Fentanyl consumption was lower in group L than group C until 12 hours after surgery. Moreover, additional fentanyl injections and the total number of button pushes appeared to be lower in group L than group C (P < 0.05). The CRP level tended to be lower in group L than group C, especially on postoperative day1 and 2 and appeared to be statistically significant. The satisfaction score was higher in group L than group C (P = 0.024). Intravenous lidocaine infusion during an operation reduces pain after a laparoscopic colectomy. PMID:25785316

Objective: To evaluate the value and safety of Diprivan and Fentany intravenous administration of analgesia in interventional procedures. Methods: Diprivan with Fentany intravenous administration for analgesia was used in eighty interventional procedures of sixty-five patients, without tracheal tube insertion. Vital signs including HR, BP, arterial oxygen saturation (SpO 2 ) and patients' reaction to operating were recorded. Results: Intravenous anesthesia was cared out successfully in eighty interventional procedures, with patients under sleeping condition during the operation, together with no pain and no agony memory of the procedure. The amount of Diprivan was 500±100 mg and Fentany was 0.2±0.025 mg. Mean arterial pressure and SpO 2 were 11.4±2.2 kPa, 10.6±2.1 kPa and 98±1.0, 96±1.5 respectively before and after ten minutes of the operation, with no significant difference. Conclusions: Diprivan with Fentany intravenous administration for interventional procedure analgesia possess good safety, painless and no agony memory of the procedure; therefor ought to be recommended.

2013-12-01

Doxapram is a respiratory stimulant used to treat hypoventilation. Here we investigated whether doxapram could also trigger respiratory neuroplasticity. Specifically, we hypothesized that intermittent delivery of doxapram at low doses would lead to long-lasting increases (i.e., facilitation) of phrenic motor output in anesthetized, vagotomized, and mechanically-ventilated rats. Doxapram was delivered intravenously in a single bolus (2 or 6mg/kg) or as a series of 3 injections (2mg/kg) at 5min intervals. Control groups received pH-matched saline injections (vehicle) or no treatment (anesthesia time control). Doxapram evoked an immediate increase in phrenic output in all groups, but a persistent increase in burst amplitude only occurred after repeated dosing with 2mg/kg. At 60min following the last injection, phrenic burst amplitude was 168±24% of baseline (%BL) in the group receiving 3 injections (Pphrenic response to doxapram (2mg/kg) was reduced by 68% suggesting that at low doses the drug was acting primarily via the carotid chemoreceptors. We conclude that intermittent application of doxapram can trigger phrenic neuroplasticity, and this approach might be of use in the context of respiratory rehabilitation following neurologic injury. © 2013.

Pain control after traumatic rib fracture is essential to avoid respiratory complications and prolonged hospitalization. Narcotics are commonly used, but adjunctive medications such as nonsteroidal anti-inflammatory drugs may be beneficial. Twenty-one patients with traumatic rib fractures treated with both narcotics and intravenous ibuprofen (IVIb) (Treatment) were retrospectively compared with 21 age- and rib fracture-matched patients who received narcotics alone (Control). Pain medication requirements over the first 7 hospital days were evaluated. Mean daily IVIb dose was 2070 ± 880 mg. Daily intravenous morphine-equivalent requirement was 19 ± 16 vs 32 ± 24 mg (P pain scores were lower in the Treatment group (P rib fractures significantly decreases narcotic requirement and results in clinically significant decreases in hospital length of stay. IVIb therapy should be initiated in patients with traumatic rib fractures to improve patient comfort and reduce narcotic requirement.

Are postoperative intravenous antibiotics necessary after bimaxillary orthognathic surgery? A prospective, randomized, double-blind, placebo-controlled clinical trial.

Science.gov (United States)

Tan, S K; Lo, J; Zwahlen, R A

2011-12-01

Postoperative antibiotic prophylaxis is often administered intravenously, despite an increased morbidity rate compared with oral application. This study investigates whether a postoperative oral antibiotic regimen is as effective as incorporation of intravenous antibiotics after bimaxillary orthognathic surgery. 42 patients who underwent bimaxillary orthognathic surgery between December 2008 and May 2010 were randomly allocated to 2 placebo-controlled postoperative antibiotic prophylaxis groups. Group 1 received oral amoxicillin 500mg three times daily; group 2 received intravenous ampicillin 1g four times daily, during the first two postoperative days. Both groups subsequently took oral amoxicillin for three more days. Clinically, the infection rate was assessed in both study groups for a period of 6 weeks after the surgery. 9 patients (21.4%) developed infection. No adverse drug event was detected. No significant difference (p=0.45) was detected in the infection rate between group 1 (3/21) and group 2 (6/21). Age, type of surgical procedures, duration of the operative procedure, surgical procedure-related events, blood loss, and blood transfusion were all found not related to infection (p>0.05). Administration of more cost-effective oral antibiotic prophylaxis, which causes less comorbidity, can be considered to be safe in bimaxillary orthognathic surgery with segmentalizations.

Management of chemotherapy-induced nausea and vomiting in patients receiving multiple-day highly or moderately emetogenic chemotherapy: role of transdermal granisetron.

Science.gov (United States)

Coluzzi, Flaminia; Mattia, Consalvo

2016-08-01

Granisetron transdermal delivery system (GTDS) is the first 5-HT3 drug to be transdermally delivered and represents a convenient alternative to oral and intravenous antiemetics for the treatment of chemotherapy-induced nausea and vomiting. GTDS is effective and well tolerated in patients receiving multiple-day moderate-to-highly emetogenic chemotherapy. In this setting noninferiority studies showed similar efficacy when GTDS was compared with intravenous and oral granisetron and intravenous palonosetron. GTDS has shown good cardiovascular safety; however, special caution is needed in patients at risk for developing excessive QTc interval prolongation and arrhythmias. So far, GTDS has been investigated for intravenous prevention in comparison with granisetron and palonosetron; however, further prospects open the route to future clinical investigations.

Opioid titration is an effective strategy for treating pain; however, titration is generally impractical in the busy emergency department (ED) setting. Our objective was to test a rapid, two-step, hydromorphone titration protocol against usual care in older patients presenting to the ED with acute severe pain. This was a prospective, randomized clinical trial of patients 65 years of age and older presenting to an adult, urban, academic ED with acute severe pain. The study was registered at http://www.clinicaltrials.gov (NCT01429285). Patients randomized to the hydromorphone titration protocol initially received 0.5 mg intravenous hydromorphone. Patients randomized to usual care received any dose of any intravenous opioid. At 15 min, patients in both groups were asked, 'Do you want more pain medication?' Patients in the hydromorphone titration group who answered 'yes' received a second dose of 0.5 mg intravenous hydromorphone. Patients in the usual care group who answered 'yes' had their ED attending physician notified, who then could administer any (or no) additional medication. The primary efficacy outcome was satisfactory analgesia defined a priori as the patient declining additional analgesia at least once when asked at 15 or 60 min after administration of the initial opioid. Dose was calculated in morphine equivalent units (MEU: 1 mg hydromorphone = 7 mg morphine). The need for naloxone to reverse adverse opioid effects was the primary safety outcome. 83.0 % of 153 patients in the hydromorphone titration group achieved satisfactory analgesia compared with 82.5 % of 166 patients in the usual care group (p = 0.91).

200 cancer patients who were due to receive fractionated chemotherapy (cisplatin greater than or equal to 15, ifosfamide greater than or equal to 1.2 or etoposide greater than or equal to 120, all mg/m2 per day) for 5 days, entered a multicentre study. Patients were randomised single-blind to receive either prophylactic intravenous granisetron (40 micrograms/kg) or alizapride (4 mg/kg followed by 4 mg/kg at 4 and 8 h post-treatment) plus dexamethasone 8 mg. Granistron was superior to the combination in preventing nausea and vomiting (54% vs. 43% complete responders). The differences were in the cisplatin-treated group. The time to first episode of moderate to severe nausea was significantly longer in the granisetron group (P = 0.03). Dosing with granisetron was more simple, with over 85% of patients requiring only a single prophylactic dose. Fewer patients receiving granisetron experienced adverse events (48% vs. 62%, P = 0.047). The frequency of constipation was, as expected, significantly higher in the granisetron group. Extrapyramidal effects, which were not noted by any granisetron patient, occurred in 5.3% of comparator patients.

Full Text Available Background : The addition of clonidine to lidocaine intravenous regional anesthesia (IVRA has been previously reported to improve postoperative analgesia in patients undergoing upper extremity surgery. Our objective was to perform a dose ranging study in order to determine the optimal dose of clonidine used with lidocaine in IVRA. Design & Setting : We performed a double-blinded randomized placebo-controlled study with 60 patients scheduled for elective endoscopic carpal tunnel release under IVRA with 50 ml lidocaine 0.5%. University-affiliated outpatient surgery center. Data collected in operating rooms, recovery room, and by telephone after discharge from surgery center. Materials & Methods : Sixty adult ASA I or II patients undergoing outpatient endoscopic carpal tunnel release under intravenous regional anesthesia.Patients were randomized into five study groups receiving different doses of clonidine in addition to 50 ml 0.5% lidocaine in their IVRA. Group A received 0 mcg/kg, group B 0.25 mcg/kg, group C 0.5 mcg/kg, group D 1.0 mcg/kg and group E 1.5 mcg/kg of clonidine.Intraoperative fentanyl, recovery room pain scores, time to first postsurgical analgesic, total number of acetaminophen/codeine tablets consumed postsurgery, incidence of sedation, hypotension and bradycardia. Results & Conclusions : There was no benefit from any dose of clonidine compared to placebo. There were no clonidine-related side effects seen within the dose range studied. In short duration minor hand surgery, the addition of clonidine to lidocaine-based intravenous regional anesthesia provides no measurable benefit.

This study was performed to test the effectiveness of topical tranexamic acid (TXA) in reducing blood loss in pelvic hemiarthoplasty surgeries compared with intravenous TXA, regarding the incidence of thromboembolic complications (deep vein thrombosis [DVT], pulmonary embolism (PE) and cerebrovascular stroke [CVS]). After obtaining institutional ethical approval 60 patients divided into three groups. Group A: Received intravenous TXA Group B: Received topical TXA Group C: Control group (placebo saline). All patients were received general anesthesia and post-operative bleeding, immediate and 24 h post-operatively, hemoglobin concentration, hematocrit, platelets and coagulation profile (prothrombin time, activated partial thromboplastin time and international normalized ratio) baseline, immediate and 24 h post-operatively. Thromboelastography was recorded baseline, immediate and 24 h post-operatively. Incidence of DVT, PE and CVS was recorded. There was statistical significant elevation hemoglobin concentration and hematocrit in both Groups A and B, significant increase in blood loss in Group C, significant increase in number of patients receiving blood in Group C, there was a significant decrease in "r" and "k" times and a significant increase in maximum amplitude and α-angle in Group A, statistically significant increase in the incidence of thromboembolic events in the form of DVT, PE and CVS in Group A. Topical TXA is effective in decreasing post-operative blood loss with possible side-effects of this route of administration.

Extending the therapeutic window of intravenous thrombolysis for acute ischemic stroke beyond the established 4.5-hour limit is of critical importance in order to increase the proportion of thrombolysed stroke patients. In this setting, the capacity of MRI to select acute stroke patients for reperfusion therapies in delayed time windows has been and is being tested in clinical trials. However, whether the more available and cost-effective perfusion computed tomography (PCT) may be useful to select candidates for delayed intravenous thrombolysis remains largely unexplored. We aimed to evaluate the safety and efficacy of PCT-guided intravenous thrombolysis beyond 4.5 h after stroke onset. We prospectively studied all consecutive acute ischemic stroke patients treated with intravenous tissue plasminogen activator (tPA) in our stroke unit between January 2008 and December 2010. Patients treated within 0- 4.5 h were treated according to non-contrast CT (NCCT) criteria. Beyond 4.5 h, patients received intravenous tPA according to PCT criteria, i.e. an infarct core on cerebral blood volume (CBV) maps not exceeding one third of the middle cerebral artery (MCA) territory and tissue at risk as defined by mean transit time-CBV mismatch greater than 20%. Predetermined primary endpoints were symptomatic hemorrhagic transformation and favorable long-term outcome, while early neurological improvement and MCA recanalization were considered secondary endpoints. Statistical analysis included bivariate comparisons between the two groups for each endpoint and logistic regression models when significance was found in bivariate analyses. This study was approved by our local ethics committee. A total of 245 patients received intravenous thrombolysis. After the groups were matched by baseline National Institutes of Health Stroke Scale score, 172 patients treated at 4.5 h were finally included. Early and late groups were comparable regarding baseline variables; only cardioembolic etiology

This prospective, randomized, placebo-controlled study evaluated the effects of dexketoprofen as an adjunct to lidocaine in intravenous regional anaesthesia (IVRA) or as a supplemental intravenous (i.v.) analgesic. Patients scheduled for elective hand or forearm soft-tissue surgery were randomly divided into three groups. All 45 patients received 0.5% lidocaine as IVRA. Dexketoprofen was given either i.v. or added into the IVRA solution and the control group received an equal volume of saline both i.v. and as part of the IVRA. The times of sensory and motor block onset, recovery time and postoperative analgesic consumption were recorded. Compared with controls, the addition of dexketoprofen to the IVRA solution resulted in more rapid onset of sensory and motor block, longer recovery time, decreased intra- and postoperative pain scores and decreased paracetamol use. It is concluded that coadministration of dexketoprofen with lidocaine in IVRA improves anaesthetic block and decreases postoperative analgesic requirements.

Patients treated with intravenous zoledronic acid 5 mg for osteoporosis may experience post-dose influenza-like symptoms. Oral acetaminophen/paracetamol or ibuprofen administered 4 h post-infusion reduced the proportion of patients with increased oral temperature and worsening post-infusion symptom scores vs. placebo, thus providing an effective strategy for the treatment of such symptoms. Once-yearly intravenous zoledronic acid 5 mg is a safe and effective treatment for postmenopausal osteoporosis. This study assessed whether transient influenza-like post-dose symptoms associated with intravenous infusion of zoledronic acid can be reduced by post-dose administration of acetaminophen/paracetamol or ibuprofen. In an international, multicenter, randomized, double-blind, double-dummy parallel-group study, bisphosphonate-naïve postmenopausal women with osteopenia (n = 481) were randomized to receive zoledronic acid 5 mg + acetaminophen/paracetamol (n = 135), ibuprofen (n = 137) or placebo (n = 137), or placebo + placebo (n = 72). Acetaminophen/paracetamol and ibuprofen were administered every 6 h for 3 days beginning 4 h post-infusion. The proportion of patients with increased oral temperature (≥1°C above 37.5°C) and with worsening post-infusion symptom scores over 3 days was significantly lower in patients receiving ibuprofen (36.8% and 48.5%) or acetaminophen/paracetamol (37.3% and 46.3%) vs. those receiving placebo (63.5% and 75.9%, respectively; all p paracetamol or ibuprofen. Oral acetaminophen/paracetamol or ibuprofen effectively managed the transient influenza-like symptoms associated with zoledronic acid 5 mg.

Intravenous administration of mesenchymal stem cells (MSCs) has been recently shown to enhance functional recovery after stroke and spinal cord injury. The therapeutic properties of MSCs are attributed to their secretion of a variety of potent antiinflammatory and neurotrophic factors. We hypothesize that intravenous administration of MSCs after recurrent laryngeal nerve (RLN) injury in the rat may enhance functional recovery. Animal Research. Twelve 250-gram Sprague-Dawley rats underwent a controlled crush injury to the left RLN. After confirming postoperative vocal fold immobility, each rat was intravenously infused with either green fluorescent protein-expressing MSCs or control media in a randomized and blinded fashion. Videolaryngoscopy was performed weekly. The laryngoscopy video recordings were reviewed and rated by a fellowship-trained laryngologist who remained blinded to the intervention using a 0 to 3 scale. At 1 week postinjury, the MSC-infused group showed a trend for higher average functional recovery scores compared to the control group (2.2 vs 1.3), but it did not reach statistical significance (P value of 0.06). By 2 weeks, however, both groups exhibited complete return of function. These pilot data indicate that with complete nerve transection by crush injury of the RLN in rat, there is complete recovery of vocal fold mobility at 2 weeks. At 1 week postinjury, animals receiving intravenous infusion of MSCs showed a trend for greater functional recovery, suggesting a potential beneficial effect of MSCs; however, this did not reach statistical significance. Therefore, no definite conclusions can be drawn from these data and further study is required. N/A. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Nasal administration of many opioids demonstrates rapid uptake and fast onset of action. Nasal administration may be an alternative to intravenous and oral administration of methadone and was therefore studied in human volunteers. The study was approved by the Institutional Review Board of the University of Washington, Seattle. Eight healthy volunteers (6 men and 2 women) aged 19 to 33 years were enrolled after informed written consent was obtained. Subjects received 10 mg methadone hydrochloride nasally, orally, or intravenously on 3 separate occasions in a crossover design. Nasal methadone (50 mg/mL in aqueous solution) was given as a 100-microL spray in each nostril (Pfeiffer BiDose sprayer). Blood samples for liquid chromatography-mass spectrometry analyses of methadone and the metabolite 2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolinium were drawn for up to 96 hours. The methadone effect was measured by noninvasive infrared pupilometry coincident with blood sampling. Nasal uptake of methadone was rapid, with maximum plasma concentrations occurring within 7 minutes. The maximum effects of intravenous, nasal, and oral methadone, on the basis of dark-adapted pupil diameter, were reached in about 15 minutes, 30 minutes, and 2 hours, respectively. The respective durations were 24, 10, and 8 hours. Both nasal and oral bioavailabilities were 0.85. Subjects reported that nasal methadone caused a burning sensation. Nasal administration of methadone results in rapid absorption and onset of effect and high bioavailability, which was greater than that reported for other nasal opioids, with a similar duration of effect. Nasal administration may be an alternative route of methadone administration; however, improved formulations are desirable to reduce nasal irritation.

Indications for direct visualization of the bile ducts include bile duct dilatation demonstrated by ultrasound or computed tomography (CT) scanning, where the cause of the bile duct dilatation is uncertain or where the anatomy of bile duct obstruction needs further clarification. Another indication is right upper quadrant pain, particularly in a post-cholecystectomy patient, where choledocholithiasis is suspected. A possible new indication is pre-operative evaluation prior to laparoscopic cholecystectomy. The bile ducts are usually studied by endoscopic retrograde cholangiopancreatography (ERCP), or, less commonly, trans-hepatic cholangiography. The old technique of intravenous cholangiography has fallen into disrepute because of inconsistent bile-duct opacification. The advent of spiral CT scanning has renewed interest in intravenous cholangiography. The CT technique is very sensitive to the contrast agent in the bile ducts, and angiographic and three-dimensional reconstructions of the biliary tree can readily be obtained using the CT intravenous cholangiogram technique (CT IVC). Seven patients have been studied using this CT IVC technique, between February 1995 and June 1996, and are the subject of the present report. Eight further studies have since been performed. The results suggest that CT IVC could replace ERCP as the primary means of direct cholangiography, where pancreatic duct visualization is not required. (authors)

The goal of this study was to investigate whether intravenous infusion of 1000 ml 40% calcium borogluconate combined with the oral adminstration of 500 g sodium phosphate leads to a better cure rate and longer-lasting normocalcaemia and normophosphataemia than standard intravenous treatment with 500 ml calcium borogluconate in cows with parturient paresis. Forty recumbent cows with hypocalcaemia and hypophosphataemia were alternately allocated to group A or B. Cows of both groups were treated intravenously with 500 ml 40% calcium borogluconate, and cows of group B additionally received another 500 ml calcium borogluconate via slow intravenous infusion and 500 g sodium phosphate administered via an orogastric tube. Thirty-two cows stood within 8 hours after the start of treatment and 8 did not; of the 32 cows that stood, 18 belonged to group A and 14 to group B (90% of group A vs. 70% of group B; P = 0.23). Seven cows relapsed; of these and the 8 that did not respond to initial treatment, 10 stood after two standard intravenous treatments. Downer cow syndrome occurred in 5 cows, 3 of which recovered after aggressive therapy. The overall cure rate did not differ significantly between groups A and B. Twelve (60%) cows of group A and 14 (70%) cows of group B were cured after a single treatment and of the remaining 14, 11 were cured after two or more treatments. Two downer cows were euthanized and one other died of heart failure during treatment. Serum calcium concentrations during the first eight hours after the start of treatment were significantly higher in group B than in group A, and oral sodium phosphate caused a significant and lasting increase in inorganic phosphate. More cows of group B than group A were cured after a single treatment (P > 0.05). These findings, although not statistically significant, are promising and should be verified using a larger number of cows.

To evaluate the reliability and validity of a previously derived clinical dehydration scale (CDS) in a cohort of children with gastroenteritis and evidence of dehydration. Participants were 226 children older than 3 months who presented to a tertiary care emergency department and required intravenous rehydration. Reliability was assessed at treatment initiation, by comparing the scores assigned independently by a trained research nurse and a physician. Validity was assessed by using parameters reflective of disease severity: weight gain, baseline laboratory results, willingness of the physician to discharge the patient, hospitalization, and length of stay. Interobserver reliability was moderate, with a weighted κ of 0.52 (95% confidence interval [CI] 0.41, 0.63). There was no correlation between CDS score and percent weight gain, a proxy measure of fluid deficit (Spearman correlation coefficient = -0.03; 95% CI -0.18, 0.12). There were, however, modest and statistically significant correlations between CDS score and several other parameters, including serum bicarbonate (Pearson correlation coefficient = -0.35; 95% CI -0.46, -0.22) and length of stay (Pearson correlation coefficient = 0.24; 95% CI 0.11, 0.36). The scale's discriminative ability was assessed for the outcome of hospitalization, yielding an area under the receiver operating characteristic curve of 0.65 (95% CI 0.57, 0.73). In children administered intravenous rehydration, the CDS was characterized by moderate interobserver reliability and weak associations with objective measures of disease severity. These data do not support its use as a tool to dictate the need for intravenous rehydration or to predict clinical course.

A European reassessment has led to identical changes in the summaries of product characteristics (SPCs) for all intravenous iron-containing products: the risk of serious adverse effects is now highlighted, underlining the fact that intravenous iron-containing products should only be used when the benefits clearly outweigh the harms. Unfortunately, iron dextran still remains on the market despite a higher risk of hypersensitivity reactions than with iron sucrose.

Full Text Available Background: Propofol has the disadvantage of causing pain or discomfort on injection. The aim of the study was to assess the efficacy of pretreatment with various drugs to alleviate the propofol injection pain. Methods: One hundred American Society of Anesthesiology (ASA I and II adults, scheduled for various elective surgical procedures under general anesthesia (GA, were included in the study. They were randomly divided into four groups having 25 patients in each group. Group A received pretreatment with intravenous (i.v. magnesium sulfate, group B received i.v. granisetron, group C received i.v. nitroglycerine and group D was the control group. One-fourth of the total calculated induction dose of propofol was administered over a period of 5 seconds. The patients were asked about the pain on injection. The intensity of pain was assessed using verbal response. A score of 0-3 which corresponds to no, mild, moderate and severe pain was recorded. Results: All the three drugs reduced the incidence and intensity of pain on propofol injection but the order of efficacy in attenuation of pain on the propofol injection was granisetron > nitroglycerine > magnesium sulfate > control. Conclusion: Granisetron was the most effective followed by nitroglycerine and magnesium sulfate in attenuating pain on propofol intravenous injection.

The effects of concurrent atorvastatin therapy on the pharmacokinetics of intravenous midazolam.

LENUS (Irish Health Repository)

Mc Donnell, C G

2012-02-03

Midazolam is a commonly used anaesthetic agent and is metabolised by the 3A4 isoform of the cytochrome P450 enzyme system. Atorvastatin is also metabolised by cytochrome P450 3A4 and, in vitro, atorvastatin inhibits the cytochrome P450 3A4-mediated metabolism of mexazolam. We hypothesised that concurrent administration of atorvastatin and midazolam would result in altered midazolam pharmacokinetics. Fourteen patients scheduled to undergo general anaesthesia for elective surgery were recruited in a matched pair design to receive intravenous midazolam (0.15 mg.kg-1). Of these patients, seven were taking long-term atorvastatin. Atorvastatin patients demonstrated a greater area under the curve (889.4 (standard deviation 388.6) ng-h.ml-1) vs. control patients (629.1 (standard deviation 197.2) ng-h.ml-1) (p < 0.05). Patients taking atorvastatin also demonstrated a decreased clearance (0.18 (standard deviation 0.08) l-kg. h-1) vs. control patients (0.27 (standard deviation 0.08) l-kg.h-1) (p < 0.05). This study suggests that chronically administered atorvastatin decreases the clearance of intravenously administered midazolam.

The authors have frequently seen myocardial infarction after renal transplantation in patient with type I diabetes, and treadmill T1-201 testing in these patients have been inadequate. The authors evaluated dipyridamole (DP) as a substitute for treadmill stress. Because intravenous DP was not approved in the United States at the time of the study, the oral formulation wax used for some patients. The authors have prospectively evaluated 80 uremic diabetics (40 received oral T1-201; 40 received intravenous T1-201). Angiogram and scan observers were blinded. There was not difference in the accuracy of the two routes of administration. Pooling the data gave a sensitivity of 86% and a specificity of 79%. However, their disease prevalence was high (52%), which precluded the use of any screening test. The authors now have recommended angiography for these patients

Full Text Available Rationale: Intravenous administration of Glutamine dipeptides (Gln has been proposed as treatment of oral mucositis following a bone marrow transplant (BMT. Objective: To establish the effects of intravenous Gln supplementation upon the severity of oral mucositis after BMT. Study design: Retrospective, analytical. Study serie: Records from 25 patients (Males: 56.0%; BMT cause: Leukemia: 64.0% who developed oral mucositis (Grades III – IV: 48.0% after BMT (Autologous: 44.0% at the "Juan Tanca Marengo" Hospital (Guayaquil, Ecuador between 2009 – 2017. Glutamine source: Dipeptiven©®: 13 grams of Gln suspended in 100 milliliters of a 20% solution of the alanine-glutamine dipeptide (Fresenius-Kabi©®, Germany. Materials and Methods: Gln-treated patients received 3(4.0% of the treatment leg, 5 (20.0%; 6 (12.0%; 7 (48.0%; or 10 (16.0% doses of the dipeptide until resolution of the symptoms. Impact of Gln was estimated from changes observed in the severity and duration of mucositis, white blood cell counts, and body weight regarding 25 non-Gln treated patients (Males: 68.0%; Leukemias: 32.0%; Autologous graft: 68.0%; Grade III – IV mucositis: 48.0%. Results: Intravenously-administered Gln shortened duration of oral mucositis: Gln-Treated: 12.5 ± 5.1 days vs. Non-Gln Treated: 21.3 ± 17.8 days (p < 0.05. Also, intravenous Gln marginally ameliorated loss of body weight: Gln-Treated -4.5 ± 5.5% vs. Non-Gln Treated: -7.5 ± 5.7% (p = 0.07. Conclusions: Intravenous Gln administration shortens duration of oral mucositis following BMT. Gln effect might be translated to a lesser weight loss in patients with oral mucositis.

A retrospective evaluation of the efficacy of intravenous bumetanide and comparison of potency with furosemide

Directory of Open Access Journals (Sweden)

Nappi JM

2013-03-01

Full Text Available Background: The potency of intravenous bumetanide to furosemide using a ratio of 1:40 has been suggested; however, there are little data supporting this ratio. Recent drug shortages required the use of bumetanide in a large patient population, enabling further characterization of the efficacy of IV bumetanide.Objective: The primary objective of this study was to estimate a dose-response effect of IV bumetanide on urine output (UOP in all patients that received 48 hours of therapy as well as in a subgroup of patients with heart failure (HF. This subgroup was used to compare the potency of bumetanide with furosemide. A secondary safety objective described electrolyte replacement required during therapy. Methods: This was a single-center retrospective study examining the dose-response effect of IV bumetanide in patients receiving at least 48 hours of intermittent (iIV or continuous (cIV dosing, measured by UOP per mg of drug received (mL/mg. The potency of IV bumetanide was compared with furosemide in a subset of patients with HF using pre-existing data. The safety of IV bumetanide was analyzed by quantifying electrolyte replacement received during the study period.Results: The primary outcome was higher in the iIV group (n=93 at 1273 ± 844 mL/mg compared with the cIV group (n=16 at 749 ± 370 mL/mg (P=0.002. Among patients with HF who received furosemide (iIV n=30, cIV n=26 or bumetanide (iIV n=30, cIV n=3, a potency ratio of 41:1 was found for the iIV group and 34:1 for all patients with HF. There was no significant difference in electrolyte replacement between groups.Conclusion: A greater response was seen with intermittent bumetanide compared with continuous infusion bumetanide. This study supports the 40:1 dose equivalence ratio (furosemide:bumetanide in patients with HF receiving at least 48 hours of intravenous intermittent bumetanide.

Amino Acid Metabolism in Acute Renal Failure: Influence of Intravenous Essential L-Amino Acid Hyperalimentation Therapy

Science.gov (United States)

Abel, Ronald M.; Shih, Vivian E.; Abbott, William M.; Beck, Clyde H.; Fischer, Josef E.

1974-01-01

A solution of 8 essential I-amino acids and hypertonic dextrose was administered to 5 patients in acute postoperative renal failure in a program of hyperalimentation designed to decrease the patient's catabolic state and to accrue certain metabolic benefits. A sixth patient receiving intravenous glucose alone served as a control. The pretreatment plasma concentrations of amino acids in all 6 patients did not differ significantly from normal; following intravenous essential amino acids at a dose of approximately 12.6 gm/24 hours, no significant elevations out of the normal range of these substances occurred. Since urinary excretion rates did not dramatically increase, urinary loss was excluded as a possible cause for the failure of increase of plasma concentrations. The results suggest that the administration of an intravenous solution of 1-amino acids and hypertonic dextrose is associated with rapid clearance from the blood of these substances and, with a failure of increased urinary excretion, indirect evidence of amino acid utilization for protein synthesis has been obtained. Histidine supplementation in patients with acute renal failure is probably unnecessary based on the lack of significant decreases in histidine concentrations in these patients. PMID:4850497

After premedication with medetomidine (5.0 µg/kg, intravenously), anesthesia was induced with guaifenesin (100 mg/kg, intravenously) and propofol (3.0 mg/kg, intravenously) and maintained with constant rate infusions of medetomidine (0.05 µg/kg/min) and propofol (0.1 mg/kg/min). Quality of induction was judged excellent to good. Three horses showed insufficient anesthesia and received additional anesthetic. Arterial blood pressure changed within an acceptable range in all horses. Decreases in respiratory rate and hypercapnia were observed in all horses. Three horses showed apnea within a short period of time. Recovery from anesthesia was calm and smooth in all horses. The TIVA-regimen used in this study provides clinically effective anesthesia for castration in horses. However, assisted ventilation should be considered to minimize respiratory depression.

A single 3 mg or 40 μg/kg intravenous dose of granisetron combined with dexamethasone is routinely used in several countries, although the antiemetic guidelines have recommended granisetron at the dose of 1 mg or 10 μg/kg. A randomized, multicenter trial was conducted to determine the optimal intravenous granisetron dose, 1 or 3 mg, in cancer patients receiving emetogenic chemotherapy. We enrolled 365 patients and randomly assigned them to receive intravenous granisetron 3 mg (3-mg group) or 1 mg (1-mg group), combined with dexamethasone at an adequate dose fixed as per the emetic risk category. The primary end point was the proportion of patients with a complete response during the first 24 h after chemotherapy. The study demonstrated that 1 mg of granisetron was not inferior in effect to 3 mg. For the primary end point, 359 patients were evaluable according to the modified intention-to-treat (ITT) analysis. Complete protection was achieved in the modified ITT population, 90.6% and 88.8% for the 3- and 1-mg groups, respectively (p granisetron is not inferior to 3 mg when both doses are combined with dexamethasone. Therefore, 1-mg dose of intravenous granisetron should be the recommended prophylactic regimen for the prevention of acute emesis.

The aim of this study is to compare the effects of intravenous single-dose dexketoprofen trometamol and diclofenac sodium 30 minutes before the end of the surgery on relief of postoperative pain in patients undergoing laparoscopic cholecystectomy. A randomized fashion. Sixty (American Society of Anesthesiologist class I-II) patients undergoing laparoscopic cholecystectomy were divided into 2 groups Patients in group DT received 50 mg dexketoprofen trometamol, whereas patients in group DS received 75 mg diclofenac sodium, intravenously 30 minutes before the end of surgery. Postoperative pain intensity, morphine consumption with patient-controlled analgesia, time to first analgesic requirement, complications, rescue analgesic (intravenous tenoxicam 20 mg) requirement, and duration of hospital stay were recorded. Postoperative pain visual analog scale scores were similar in the follow-up periods (P > .05). Patient-controlled analgesia morphine consumption was significantly less in group DT compared with group DS in all postoperative follow-up periods (2 and 4 hours: P dexketoprofen trometamol 30 minutes before the end of surgery provided effective analgesia with reduced consumption of opioids and requirement for rescue analgesic compared with diclofenac sodium in patients undergoing laparoscopic cholecystectomy. For this reason, we believe that, as a part of multimodal analgesia, dexketoprofen trometamol provides more effective analgesia than diclofenac sodium in patients undergoing laparoscopic cholecystectomy.

Proctalgia fugax is characterized by a sudden internal anal sphincter and anorectic ring attack of pain of a short duration. Description of the influence of intravenous lidocaine treatment for proctalgia fugax. A 28-year-old patient suffering of proctalgia fugax for 8 months. Conventional treatment efforts did not improve his condition. A single dose of an intravenous lidocaine infusion completely stopped his pain attacks. Based on the experience reported in this case and the potential benefit of this treatment for proctalgia fugax, controlled studies comparing intravenous lidocaine with placebo should be conducted to confirm the observation and to provide a more concrete basis for the use of intravenous lidocaine for this indication.

Patients on total parenteral nutrition have an increased risk of developing gallstones because of gall bladder hypomotility. High dose amino acids may prevent biliary stasis by stimulating gall bladder emptying. To investigate whether intravenous amino acids also influence antroduodenal motility. Eight healthy volunteers received, on three separate occasions, intravenous saline (control), low dose amino acids (LDA), or high dose amino acids (HDA). Antroduodenal motility was recorded by perfusion manometry and duodenocaecal transit time (DCTT) using the lactulose breath hydrogen test. DCTT was significantly prolonged during LDA and HDA treatment compared with control. The interdigestive motor pattern was maintained and migrating motor complex (MMC) cycle length was significantly reduced during HDA compared with control and LDA due to a significant reduction in phase II duration. Significantly fewer phase IIIs originated in the gastric antrum during LDA and HDA compared with control. Duodenal phase II motility index was significantly reduced during HDA, but not during LDA, compared with control. Separate intravenous infusion of high doses of amino acids in healthy volunteers: (1) modulates interdigestive antroduodenal motility; (2) shortens MMC cycle length due to a reduced duration of phase II with a lower contractile incidence both in the antrum and duodenum (phase I remains unchanged whereas the effect on phase III is diverse: in the antrum phase III is suppressed and in the duodenum the frequency is increased); and (3) prolongs interdigestive DCTT.

One of the primary goals of critical care medicine is to support adequate gas exchange without iatrogenic sequelae. An emerging method of delivering supplemental oxygen is intravenously rather than via the traditional inhalation route. The objective of this study was to evaluate the gas-exchange effects of infusing cold intravenous (IV) fluids containing very high partial pressures of dissolved oxygen (>760 mm Hg) in a porcine model. Juvenile swines were anesthetized and mechanically ventilated. Each animal received an infusion of cold (13 °C) Ringer's lactate solution (30 mL/kg/hour), which had been supersaturated with dissolved oxygen gas (39.7 mg/L dissolved oxygen, 992 mm Hg, 30.5 mL/L). Arterial blood gases and physiologic measurements were repeated at 15-minute intervals during a 60-minute IV infusion of the supersaturated dissolved oxygen solution. Each animal served as its own control. Five swines (12.9 ± 0.9 kg) were studied. Following the 60-minute infusion, there were significant increases in PaO2 and SaO2 (P < 0.05) and a significant decrease in PaCO2 (P < 0.05), with a corresponding normalization in arterial blood pH. Additionally, there was a significant decrease in core body temperature (P < 0.05) when compared to the baseline preinfusion state. A cold, supersaturated dissolved oxygen solution may be intravenously administered to improve arterial blood oxygenation and ventilation parameters and induce a mild therapeutic hypothermia in a porcine model.

The use of intravenous immunoglobulin (IVIg) has been reported as an immunomodulating agent in several autoimmune diseases, including systemic lupus erythematosus (SLE). Herein we report a SLE patient with severe clinical presentation that included pericarditis, pleural effusion, nephrotic range proteinuria, leukopenia, and lymphopenia. The patient received one course of high-dose IVIg (2.8 g/kg body weight), and within a week of post-IVIg therapy, her condition significantly improved. One-month post-IVIg there were decreased proteinuria, elevated leukocytes and lymphocytes count, decrease in antinuclear and anti-dsDNA antibodies, and disappearance of pericarditis and pleuritis. This case demonstrates the efficacy of IVIg in severe SLE with various clinical manifestations.

Rolapitant is a selective, long-acting neurokinin-1 receptor antagonist, approved in the United States and Europe for prevention of delayed chemotherapy-induced nausea and vomiting in adults. This open-label study evaluated the effects of a new intravenous formulation of rolapitant on cytochrome P450 (CYP) enzyme (CYP3A, CYP1A2, CYP2C9, CYP2C19, and CYP2D6) activity. On days 1 and 14, 36 healthy volunteers received a modified Cooperstown cocktail (midazolam 3 mg [CYP3A substrate], caffeine 200 mg [CYP1A2 substrate], S-warfarin 10 mg [CYP2C9 substrate] + vitamin K 10 mg, omeprazole 40 mg [CYP2C19 substrate], and dextromethorphan 30 mg [CYP2D6 substrate]). On day 7, subjects received the modified Cooperstown cocktail after 166.5-mg rolapitant infusion. On days 21, 28, and 35, subjects received oral dextromethorphan. Maximum plasma concentration (C max ) and area under the plasma concentration-time curve (AUC 0-last ) of probe drugs post- vs pre-rolapitant administration were assessed using geometric least-squares mean ratios (GMRs) with 90%CIs. The 90%CIs of the GMRs were within the 0.80-1.25 no-effect limits for caffeine and S-warfarin C max and AUC 0-last . For midazolam C max and AUC 0-last and omeprazole C max , the 90%CIs of the GMRs were marginally outside these limits. Intravenous rolapitant coadministration increased dextromethorphan exposure, peaking 14 days post-rolapitant administration (GMRs: C max , 2.74, 90%CI 2.21-3.40; AUC 0-last , 3.36, 90%CI 2.74-4.13). Intravenous rolapitant 166.5 mg and probe drugs were well tolerated when coadministered. These data suggest that intravenous rolapitant is not an inhibitor of CYP3A, CYP2C9, CYP2C19, or CYP1A2 but is a moderate inhibitor of CYP2D6. © 2018, The American College of Clinical Pharmacology.

Full Text Available The pharmacokinetics of oxiracetam and its degraded substance (4-hydroxy-2-oxo-1-pyrrolidine acetic acid, HOPAA after oral and intravenous administration in rats were studied using an established UPLC-MS/MS method. Three groups of rats after an overnight fasted received 10 g/kg (n = 6 oxiracetam suspensions orally, and 2 g/kg (n = 6 normal or degraded oxiracetam injections intravenously via a caudal tail vein, respectively. Before the pharmacokinetic experiment, a simple safety evaluation test was conducted on the degraded oxiracetam injections containing 16.16% HOPAA in mice. There was no mortality by a single intravenous dose of 2 g/kg of degraded oxiracetam injections within two weeks, demonstrating that HOPAA was non-toxic in mice. Following intravenous administration of the normal injections, the plasma concentration-time curves of oxiracetam and HOPAA both showed a rapid elimination phase. The values of t1/2 were 3.1 ± 1.5 h for oxiracetam and 0.8 ± 0.2 h for HOPAA, and the mean residence times (MRT were 1.2 ± 0.1 h and 0.8 ± 0.1 h, respectively. Oxiracetam and HOPAA after intravenous administration of the degraded oxiracetam injections presented elimination patterns similar to those observed in the normal injections. Oral pharmacokinetic results showed that the Tmax was less than 1.5 h for the two analytes, and both had a longer t1/2 and MRT than those of intravenous administration. Contents of HOPAA in three groups were calculated based on AUC0–t values of the two analytes. The quantitative change of HOPAA in vivo was also evaluated by comparing the plasma concentrations of HOPAA and oxiracetam at the same time for every group. Additionally, the values of absolute bioavailability of oxiracetam were about 8.0% and 7.4% calculated by the normal or degraded oxiracetam injections, which were far less than the value of 75% reported in literature, indicating the necessity of further study.

Renal effects of the 2 non-ionic contrast media iopentol and iohexol were investigated and compared in a double-blind, randomized parallel study where 30 patients received iopentol, and 31 patients iohexol intravenously for abdominal CT. The dosage of contrast medium (350 mg I/ml) was 700 mg I/kg body weight. Only one patient (in the iohexol group) had an increase in serum creatinine of more than 50%. Iopentol and iohexol had no effects on the mean serum values of creatinine, urea, and β 2 -microglobulin (β 2 -MG) nor on creatinine clearance. The urinary excretion of albumin and β 2 -MG was also unchanged. The excretion of the proximal tubular enzymes alkaline phosphatase and N-acetyl-β-glucosaminidase was increased. No significant difference between iopentol and iohexol was found. (orig.)

High-dose intravenous esomeprazole is the only approved pharmacological treatment for the prevention of peptic ulcer rebleeding (currently approved in over 100 countries worldwide), but has not yet been approved in China. This study aimed to evaluate a high-dose esomeprazole intravenous regimen vs. an active control (cimetidine) for the prevention of rebleeding in Chinese patients with a high risk of peptic ulcer rebleeding who had undergone primary endoscopic hemostatic treatment. This was a parallel-group study conducted at 20 centers in China. The study comprised a randomized, double-blind, intravenous treatment phase of 72 h in which 215 patients received either high-dose esomeprazole (80 mg + 8 mg/h) or cimetidine (200 mg + 60 mg/h), followed by an open-label oral treatment phase in which all patients received esomeprazole 40 mg tablets once daily for 27 days. The primary outcome was the rate of clinically significant rebleeding within the first 72 h after initial endoscopic hemostatic therapy. Secondary outcomes included the rates of clinically significant rebleeding within 7 and 30 days; proportions of patients who had endoscopic retreatment and other surgery due to rebleeding; and number of blood units transfused. The rate of clinically significant rebleeding within 72 h was low overall (3.3%) and numerically lower in patients treated with esomeprazole compared with cimetidine (0.9% vs. 5.6%). Overall, the results of the secondary outcomes also showed a numerical trend towards superiority of esomeprazole over cimetidine. All treatments were well tolerated. In this phase 3, multicenter, randomized trial conducted in China, esomeprazole showed a numerical trend towards superior clinical benefit over cimetidine in the prevention of rebleeding in patients who had successfully undergone initial hemostatic therapy of a bleeding peptic ulcer, with a similar safety and tolerability profile. These findings suggest that esomeprazole may be an

A retrospective study of postoperative pain management. Evaluate the efficacy and safety of continuous intravenous morphine infusion for postoperative pain management in patients with idiopathic scoliosis (IS) undergoing posterior spinal fusion (PSF) and segmental spinal instrumentation (SSI). Postoperative pain is a common problem following surgery for IS. There are no published reports regarding the use of a continuous intravenous morphine infusion for this patient population. We retrospectively reviewed data regarding 339 consecutive patients with IS who underwent PSF and SSI between 1992 and 2006. All patients received intrathecal morphine after the induction of general anesthesia. Following surgery, preordered morphine infusion (0.01 mg/kg/h) was started at first reported pain. The infusion rate was titrated based on vital signs, visual analog scale (VAS) pain scores (0-10), and clinical status. It was continued until patients were able to take oral analgesics. We reviewed intrathecal morphine dosage, VAS pain scores through the third postoperative day, interval to start of morphine infusion, total morphine requirements in the first 48 hours, and any adverse reactions (nausea/vomiting, pruritus, respiratory depression, and pediatric intensive care unit admission). Mean intrathecal morphine dose was 15.5 +/- 3.9 microg/kg and mean interval to start of the intravenous morphine infusion was 17.5 +/- 5 hours. Mean VAS pain scores were 3.1, 4.5, 4.5, and 4.6 at 12 hours, 1, 2, and 3 days after surgery, respectively.The total mean morphine dose in the first 48 hours postoperatively was 0.03 +/- 0.01 mg/kg/h. Total morphine received was 1.44 +/- 0.5 mg/kg. Nausea/vomiting and pruritus, related to the morphine infusion occurred in 45 patients (13.3%) and 14 patients (4.1%), respectively. No patients had respiratory depression or required Pediatric Intensive Care Unit admission. A low frequency of adverse events and a mean postoperative VAS pain score of 5 or less

Ischemic stroke is a major cause of disability and death in the USA. Intravenous tissue plasminogen activator (t-PA) remains underutilized. With the development of newer intra-arterial reperfusion therapies, there is increased opportunity to address the more devastating large-vessel occlusions. We seek to identify the numbers of patients with stroke treated with intravenous and intra-arterial therapies, as well as to estimate the potential number of intra-arterial cases in the foreseeable future. We performed a literature search to determine case volumes of intravenous t-PA use. We extrapolated the current case volume of intra-arterial stroke therapies from the numbers of cases in which the Merci retrieval device was used. In order to estimate the potential numbers of intra-arterial stroke cases, we characterized the percentage of patients with stroke who received intra-arterial therapy at two leading stroke centers. We applied these percentages to the numbers of patients with stroke seen at the top 100, 200 and 500 stroke centers by volume. The rate of intravenous t-PA use is 2.4-3.6%, resulting in 15 000-22 000 cases/year in the USA. The estimated case volume of intra-arterial therapies is 3500-7200 in 2006. Based on data from St. Luke's Brain and Stroke Institute and Massachusetts General Hospital, approximately 5-20% of patients with ischemic stroke can be treated with intra-arterial therapies. Extrapolating this to the top 500 stroke centers by volume, the potential number of intra-arterial cases in the USA is 10 400-41 500/year. Based on the current numbers of intra-arterial cases, our theoretical model identifies a potential for significant growth of this stroke therapy.

The intravenous injection of illicit drugs and needle sharing: an historical perspective.

Science.gov (United States)

Zule, W A; Vogtsberger, K N; Desmond, D P

1997-01-01

This study reviewed the literature on the history of needle sharing and intravenous drug abuse. Reports suggest that needle sharing was practiced by drug abusers as early as 1902 in China and 1914 in the United States. Intravenous drug abuse was first mentioned in the literature in 1925. However other references suggest that some opioid users were injecting intravenously prior to 1920. Outbreaks of malaria in Egypt, the United States, and China between 1929 and 1937 were attributed to needle sharing and intravenous injection of opioids. These reports suggest that both needle sharing and intravenous drug use were common by 1937. Factors such as medical use of intravenous injections, enactment and zealous enforcement of antinarcotic laws, and interactions among drug users in institutional settings such as regional hospitals and prisons may have contributed to the spread of both needle sharing and the intravenous technique among drug abusers.

Space motion sickness is an important issue in the space medical sciences program. One of the objectives of the ongoing clinical experimental protocol Pharmacokinetics of Intranasal Scopolamine in Normal Subjects is to evaluate the pharmacodynamics of scopolamine using salivary flow rate and pH profiles and cognitive performance tests as pharmacodynamic parameters. Normal volunteers collected saliva and performed the NTI Multiresource Performance Battery tests at designed time intervals to establish control saliva flow rates, salivary pH profiles, and the characteristics of the learning curve for the performance program under normal conditions. In the clinical part of the study, saliva samples and performance test scores are collected from healthy nonsmoking subjects after receiving a single 0.4 mg dose of either intranasal, intravenous, or oral scopolamine.

The acute antiemetic effect was compared between oral azasetron and intravenous granisetron based on the 5-hydroxytryptamine(3) (5-HT(3)) receptor occupancy theory. Receptor occupancy was estimated from reported data on plasma concentrations and affinity constants to 5-HT(3) receptor. A randomized non-inferiority study comparing acute antiemetic effects between oral azasetron and intravenous granisetron was performed in 105 patients receiving the first course of carboplatin-based chemotherapy for lung cancer. Azasetron exhibited the highest 5-HT(3) receptor occupancy among various first-generation 5-HT(3) antagonists. The complete response to oral azasetron was shown to be non-inferior to that of intravenous granisetron, in which the risk difference was 0.0004 (95% confidence interval: -0.0519-0.0527). The lower limit of the confidence intervals did not exceed the negative non-inferiority margin (-0.1). The complete response during the overall period was not different (68% versus 67%). Oral azasetron was found to be non-inferior to intravenous granisetron in the acute antiemetic effect against moderately emetogenic chemotherapy.

The incidence of propofol injection pain during induction of general anesthesia varies from 28% to 90%. This prospective, randomized, double-blind, placebo-controlled study evaluated the effect of dexamethasone and granisetron for reducing the incidence and severity of propofol injection pain. A total of 227 female subjects received 5 mL of preservative-free saline, 1 mg granisetron (5 ml), or 0.15 mg/kg of dexamethasone (5 ml), intravenously, following exsanguination and occlusion of the veins of the arm. This was followed by a 0.5 mg/kg injection of propofol. Pain scores and intensity of pain recorded immediately following the injection of propofol. Hemodynamic parameters and O 2 sat were recorded 1, 3, 5, and 10 min after propofol injection. The incidence pain following the injection of propofol was significantly decreased with both granisetron and dexamethasone (50.7% and 49.4%). Mean pain score in granisetron group was 3.16 ± 1.23, dexamethasone was 2.73 ± 1.03, and in saline group was 4.82 ± 1.73 ( P = 0.001). Mean pain intensity in granisetron group was 1.16 ± 0.18, dexamethasone was 1.26 ± 0.14, and in saline group was 2.2 ± 0.99 ( P = 0.001). There were no differences in either mean arterial pressure or O 2 Sate at any time point after drugs injection among the groups. There was a significant difference in pulse rate in third minutes between three groups and in the group who received granisetron was lesser ( P = 0.04). Pretreatment with intravenous granisetron (1 mg) and dexamethasone (0.15 mg/kg) before injection of propofol is effective and safe in reducing the incidence and severity of pain due to propofol injection.

Hemodynamic parameters and O2sat were recorded 1, 3, 5, and 10 min after propofol injection. Results: The incidence pain following the injection of propofol was significantly decreased with both granisetron and dexamethasone (50.7% and 49.4%. Mean pain score in granisetron group was 3.16 ± 1.23, dexamethasone was 2.73 ± 1.03, and in saline group was 4.82 ± 1.73 (P = 0.001. Mean pain intensity in granisetron group was 1.16 ± 0.18, dexamethasone was 1.26 ± 0.14, and in saline group was 2.2 ± 0.99 (P = 0.001. There were no differences in either mean arterial pressure or O2Sate at any time point after drugs injection among the groups. There was a significant difference in pulse rate in third minutes between three groups and in the group who received granisetron was lesser (P = 0.04. Conclusion: Pretreatment with intravenous granisetron (1 mg and dexamethasone (0.15 mg/kg before injection of propofol is effective and safe in reducing the incidence and severity of pain due to propofol injection.

Background: The incidence of propofol injection pain during induction of general anesthesia varies from 28% to 90%. This prospective, randomized, double-blind, placebo-controlled study evaluated the effect of dexamethasone and granisetron for reducing the incidence and severity of propofol injection pain. Materials and Methods: A total of 227 female subjects received 5 mL of preservative-free saline, 1 mg granisetron (5 ml), or 0.15 mg/kg of dexamethasone (5 ml), intravenously, following exsanguination and occlusion of the veins of the arm. This was followed by a 0.5 mg/kg injection of propofol. Pain scores and intensity of pain recorded immediately following the injection of propofol. Hemodynamic parameters and O2 sat were recorded 1, 3, 5, and 10 min after propofol injection. Results: The incidence pain following the injection of propofol was significantly decreased with both granisetron and dexamethasone (50.7% and 49.4%).

The study aimed to investigate the analgesic effect of a combination of intravenous flurbiprofen axetil and opioids, and evaluate the relationship between refractory pain relief and plasma β-endorphin levels in cancer patients. A total of 120 cancer patients was randomly divided into two groups, 60 patients took orally morphine sulfate sustained-release tablets in group A, and another 60 patients receiving the combination treatment of intravenous flurbiprofen axetil and opioid drugs in group B. After 7 days, pain relief, quality of life improvement and side effects were evaluated. Furthermore, plasma β-endorphin levels were measured by radioimmunoassay. With the combination treatment of intravenous intravenous flurbiprofen axetil and opioids, the total effective rate of pain relief rose to 91.4%, as compared to 82.1% when morphine sulfate sustained-release tablet was used alone. Compared with that of group A, the analgesic effect increased in group B (p=0.031). Moreover, satisfactory pain relief was associated with a significant increase in plasma β-endorphin levels. After the treatment, plasma β-endorphin level in group B was 62.4±13.5 pg/ml, which was higher than that in group A (45.8±11.2 pg/ml) (pflurbiprofen axetil and opioids can enhance the analgesic effect of opioid drugs by increasing plasma β-endorphin levels, which would offer a selected and reliable strategy for refractory cancer pain treatment.

Laboratory investigation in rats submitted to experimental spinal cord injury (SCI). To determine the effect of acute SCI on the pharmacokinetics of diclofenac, a marker drug of intermediate hepatic extraction, administered by the intravenous and the oral routes. Female Wistar rats were submitted to complete section of the spinal cord at the T8 level. SCI and sham-injured rats received 3.2 mg kg(-1) of diclofenac sodium either intravenously or orally, diclofenac concentration was measured in whole blood samples and pharmacokinetic parameters were estimated. Diclofenac was not selected as test drug because of its therapeutic properties, but because to its biopharmaceutical properties, that is, intermediate hepatic extraction. Diclofenac bioavailability after intravenous administration was increased in injured rats compared with controls due to a reduced clearance. In contrast, oral diclofenac bioavailability was diminished in SCI animals due to a reduction in drug absorption, which overrides the effect on clearance. Acute SCI induces significant pharmacokinetic changes for diclofenac, a marker drug with intermediate hepatic extraction. SCI-induced pharmacokinetic changes are not only determined by injury characteristics, but also by the route of administration and the biopharmaceutical properties of the studied drug.

BACKGROUND: Common intravenous recombinant tissue plasminogen activator (IV rt-PA) exclusion criteria may substantially limit the use of thrombolysis. Preliminary data have shown that the SMART (Simplified Management of Acute stroke using Revised Treatment) criteria greatly expand patient...... eligibility by reducing thrombolysis exclusions, but they have not been assessed on a large scale. We evaluated the safety and efficacy of general adoption of SMART thrombolysis criteria to a large regional stroke network. METHODS: Retrospective analysis of consecutive patients who received IV thrombolysis...... within a regional stroke network was performed. Patients were divided into those receiving thrombolysis locally versus at an outside hospital. The primary outcome was modified Rankin Scale score (≤1) at discharge and the main safety outcome was symptomatic intracranial hemorrhage (sICH) rate. RESULTS...

Hepatic glycogen in humans. II. Gluconeogenetic formation after oral and intravenous glucose

Radziuk, J.

1989-01-01

The amount of glycogen that is formed by gluconeogenetic pathways during glucose loading was quantitated in human subjects. Oral glucose loading was compared with its intravenous administration. Overnight-fasted subjects received a constant infusion or [3- 3 H]glucose and a marker for gluconeogenesis, [U- 14 C]lactate or sodium [ 14 C]bicarbonate [ 14 C]bicarbonate. An unlabeled glucose load was then administered. Postabsorptively, or after glucose infusion was terminated, a third tracer ([6- 3 H]glucose) infusion was initiated along with a three-step glucagon infusion. Without correcting for background stimulation of [ 14 C]glucose production or for dilution of 14 C with citric acid cycle carbon in the oxaloacetate pool, the amount of glycogen mobilized by the glucagon infusion that was produced by gluconeogenesis during oral glucose loading was 2.9 +/- 0.7 g calculated from [U- 14 C]-lactate incorporation and 7.4 +/- 1.3 g calculated using [ 14 C]bicarbonate as a gluconeogenetic marker. During intravenous glucose administration the latter measurement also yielded 7.2 +/- 1.1 g. When the two corrections above are applied, the respective quantities became 5.3 +/- 1.7 g for [U- 14 C]lactate as tracer and 14.7 +/- 4.3 and 13.9 +/- 3.6 g for oral and intravenous glucose with [ 14 C]bicarbonate as tracer (P less than 0.05, vs. [ 14 C]-lactate as tracer). When [2- 14 C]acetate was infused, the same amount of label was incorporated into mobilized glycogen regardless of which route of glucose administration was used. Comparison with previous data also suggests that 14 CO 2 is a potentially useful marker for the gluconeogenetic process in vivo

Dichloroacetate (DCA) is a putative environmental hazard, owing to its ubiquitous presence in the biosphere and its association with animal and human toxicity. We sought to determine the kinetics of environmentally relevant concentrations of 1,2-(13)C-DCA administered to healthy adults. Subjects received an oral or intravenous dose of 2.5 microg/kg of 1,2-(13)C-DCA. Plasma and urine concentrations of 1,2-(13)C-DCA were measured by a modified gas chromatography-tandem mass spectrometry method. 1,2-(13)C-DCA kinetics was determined by modeling using WinNonlin 4.1 software. Plasma concentrations of 1,2-(13)C-DCA peaked 10 minutes and 30 minutes after intravenous or oral administration, respectively. Plasma kinetic parameters varied as a function of dose and duration. Very little unchanged 1,2-(13)C-DCA was excreted in urine. Trace amounts of DCA alter its own kinetics after short-term exposure. These findings have important implications for interpreting the impact of this xenobiotic on human health.

Full Text Available Intravenous immunoglobulin (IVIG is used in the treatment of neuropathy. This case report presents, for the first time, a patient with severe periodontal destruction after chronic therapy with IVIG. The patient reported having extracted his maxillary anterior teeth himself due to high mobility. Clinical examination and radiographic images show a generalized and severe periodontitis. No significant alterations in genetic or microbiological features were observed. The present case suggests that periodontal disease aggravation could be considered a new adverse effect of IVIG therapy. Postulated mechanisms are immune complexes formation, complement activation, and a direct effect in osteoclasts. In conclusion, it is important that patients that will receive IVIG treatment underwent dental evaluation.

Ari Zekcer

Full Text Available Abstract Background Tranexamic acid (TXA is widely used in orthopedic surgery to reduce perioperative bleeding. Since TXA inhibits fibrinolysis, there is concern that it may increase the risk of thromboembolic events. Objectives To verify the prevalence of deep venous thrombosis (DVT in patients receiving TXA during total knee arthroplasty and to compare topical with intravenous administration of the drug. Methods All patients admitted for total knee arthroplasty due to primary arthrosis between June and November of 2014 were recruited consecutively. Thirty patients were randomized to a “topical group” (1.5 g TXA diluted in 50ml saline sprayed over the area operated, before tourniquet release, 30 to an “intravenous group” (20mg/kg TXA in 100 ml of saline, given at the same time as anesthesia, and 30 to a control group (100 ml of saline, given at the same time as anesthesia. All patients had duplex ultrasound scans of the legs on the 15th postoperative day. Results Deep venous thrombosis events occurred in five of the 90 patients operated (one out of 30 in the topical group [3.3%], four out of 30 in the control group [13.3%], and zero in the intravenous group. All were confirmed by duplex ultrasound scans and all were asymptomatic. Prevalence rates of DVT were similar between groups (p = 0.112 for control vs. intravenous; p = 0.353 for control vs. topical; and p =1.000 for intravenous vs. topical, according to two-sided exact tests. Conclusions Both topical and intravenous administration of TXA are safe with regard to occurrence of DVT, since the number of DVT cases in patients given TXA was not different to the number in those given placebo.

Among the various pharmacological options to decrease peri-operative bleeding, tranexamic acid appears to be one of the most interesting. Several trials have consistently documented the efficacy of this synthetic drug in reducing the risk of blood loss and the need for allogeneic blood transfusion in patients undergoing total hip and knee arthroplasty. The safety of intravenous tranexamic acid in major orthopaedic surgery, particularly regarding the risk of venous thromboembolism, was systematically analysed in this review. A systematic search of the literature identified 73 randomised controlled trials involving 4,174 patients and 2,779 controls. The raw overall incidence of venous thromboembolism was 2.1% in patients who received intravenous tranexamic acid and 2.0% in controls. A meta-analytic pooling showed that the risk of venous thromboembolism in tranexamic acid-treated patients was not significantly different from that of controls (risk difference: 0.01%, 95% confidence interval [CI]: −0.05%, 0.07%; risk ratio: 1.067, 95% CI: 0.760–1.496). Other severe drug-related adverse events occurred very rarely (0.1%). In conclusion, the results of this systematic review and meta-analysis show that intravenous tranexamic acid is a safe pharmacological treatment to reduce blood loss and transfusion requirements in patients undergoing major orthopaedic surgery.

Full Text Available Abstract Backgrounds We conducted a pilot study of the infusion of intravenous autologous cord blood (CB in children with cerebral palsy (CP to assess the safety and feasibility of the procedure as well as its potential efficacy in countering neurological impairment. Methods Patients diagnosed with CP were enrolled in this study if their parents had elected to bank their CB at birth. Cryopreserved CB units were thawed and infused intravenously over 10~20 minutes. We assessed potential efficacy over 6 months by brain magnetic resonance imaging (MRI-diffusion tensor imaging (DTI, brain perfusion single-photon emission computed tomography (SPECT, and various evaluation tools for motor and cognitive functions. Results Twenty patients received autologous CB infusion and were evaluated. The types of CP were as follows: 11 quadriplegics, 6 hemiplegics, and 3 diplegics. Infusion was generally well-tolerated, although 5 patients experienced temporary nausea, hemoglobinuria, or urticaria during intravenous infusion. Diverse neurological domains improved in 5 patients (25% as assessed with developmental evaluation tools as well as by fractional anisotropy values in brain MRI-DTI. The neurologic improvement occurred significantly in patients with diplegia or hemiplegia rather than quadriplegia. Conclusions Autologous CB infusion is safe and feasible, and has yielded potential benefits in children with CP.

Objective: To study the imaging findings of the chest disease due to intravenous heroin abuse. Methods: Twenty-five cases of clinically confirmed chest disease due to intravenous heroin abuse were retrospectively analyzed. 25 cases had conventional X-ray film, 6 cases had CT scanning, and 6 cases had echocardiography scanning. Results: On X-ray and CT, the following signs were found: lung making manifold (n = 5), small patchy shadow (n = 15), pneumatocele (n = 16), small cavity (n = 16), small node (n = 7), pleural effusion (n = 8 ), pneumothorax (n = 2), hydropneumothorax (n = 6), pulmonary edema (n = 2), megacardia (n = 11), multiple-shaped lesion (n = 20). On echocardiography, tricuspid vegetation (n = 4) and tricuspid insufficiency (n = 4) were found. Conclusion: The X-ray and CT manifestations of chest inflammation due to intravenous heroin abuse are multiple. The multiple small cavities and pneumatoceles sign are of some value in the diagnosis of lung inflammation due to intravenous heroin abuse among young patients

Intravenous catheters have been indispensable tools of modern medicine. Although intravenous applications can be used for a multitude of purposes, these applications may cause complications, some of which have serious effects. Of these complications, the most commonly observed is phlebitis. This study was conducted to determine the effect of catheter indwell time on phlebitis development during peripheral intravenous catheter administration. This study determined the effect of catheter indwell time on phlebitis development during peripheral intravenous catheter administration. The study included a total of 103 individuals who were administered 439 catheters and satisfied the study enrollment criteria at one infectious diseases clinic in Istanbul/Turkey. Data were compiled from Patient Information Forms, Peripheral Intravenous Catheter and Therapy Information Forms, reported grades based on the Visual Infusion Phlebitis Assessment Scale, and Peripheral Intravenous Catheter Nurse Observation Forms. The data were analyzed using SPSS. Results : The mean patient age was 53.75±15.54 (standard deviation) years, and 59.2% of the study participants were men. Phlebitis was detected in 41.2% of peripheral intravenous catheters, and the rate decreased with increased catheter indwell time. Analyses showed that catheter indwell time, antibiotic usage, sex, and catheterization sites were significantly associated with development of phlebitis. The results of this study show that catheters can be used for longer periods of time when administered under optimal conditions and with appropriate surveillance.

The concentration of plutonium has been determined along the length of the hair of a female subject who received 11.1 kBq (0.3 μCi) of 239 Pu by intravenous injection in 1945. The subject succumbed to her preexisting illness 518 days post-injection. The growth rate of hair given for females in ICRP is 0.36 mm/day, and so a half-length of 43 +- 9 mm corresponds to a half-time of 120 +- 25 days. However, since plutonium was found in the most distal portion of the hair, an average growth rate of at least 280 mm/518 days, or 0.54 mm/ day is indicated for this individual. This value yields a half-time of 80 +- 20 days for the long-lived component of plutonium concentration in the hair and therefore also in the blood. This half-time is in excellent agreement with that of 88 +- 13 days found for the plutonium injection cases

The safety of IV ibuprofen as assessed in ten sponsored clinical studies is presented in this analysis. Overall, 1,752 adult patients have been included in safety and efficacy trials over 11 years; 1,220 of these patients have received IV ibuprofen and 532 received either placebo or comparator medication. The incidence of adverse events (AEs, serious AEs, and changes in vital signs and clinically significant laboratory parameters have been summarized and compared to patients receiving placebo or active comparator drug. Overall, IV ibuprofen has been well tolerated by hospitalized and outpatient patients when administered both prior to surgery and postoperatively as well as for nonsurgical pain or fever. The overall incidence of AEs is lower in patients receiving IV ibuprofen as compared to those receiving placebo in this integrated analysis. Specific analysis of hematological and renal effects showed no increased risk for patients receiving IV ibuprofen. A subset analysis of elderly patients suggests that no dose adjustment is needed in this higher risk population. This integrated safety analysis demonstrates that IV ibuprofen can be safely administered prior to surgery and continued in the postoperative period as a component of multimodal pain management.Keywords: NSAID, surgical pain, fever, perioperative analgesia, critical care, multimodal pain management

Migraine is a common form of headache that is a major burden for patients who often seek emergency care. The goal of this study was to compare the effectiveness of intravenous non-steroidal anti-inflammatory medication (dexketoprofen) with paracetamol (acetaminophen) in the treatment of an acute migraine attack. This prospective, randomised, double blind, controlled study was conducted in a tertiary care emergency unit. Study patients were randomised into two groups to receive either 50 mg of dexketoprofen trometamol or 1000 mg of paracetamol intravenously by rapid infusion in 150 mL of normal saline. Pain reduction was measured at baseline, and after 15 and 30 min, using a Visual Analogue Scale (VAS)) as the primary outcome. VAS is a measurement tool ranging from 0 (no pain) to 100 mm (worst pain). 200 patients were included in the final analysis. Mean (SD) age of the study subjects was 30.1 ± 11 years and 81% (n=162) were women. Median reduction in VAS score at 30 min was 56 (IQR 30-78.5) for the paracetamol group and 55 (IQR 34-75) for the dexketoprofen group, with a difference of 1 mm (95% CI -7 to 10) between the two groups. Intravenous paracetamol and dexketoprofen appear to produce equivalent pain relief for migraine in the emergency department. CLINICALTRIALS.GOV NO: NCT01730326.

Severe malaria remains a major cause of mortality and morbidity for children living in many tropical regions. With the emergence of strains of Plasmodium falciparum resistant to both chloroquine and quinine, alternative antimalarial agents are required. The artemisinin group of compounds are rapidly effective in severe disease when given by intramuscular or intravenous injection. However, these routes of administration are not always available in rural areas. In an open, randomized comparison 109 Vietnamese children, aged between 3 months and 14 years, with severe P.falciparum malaria, were allocated at random to receive artemisinin suppositories followed by mefloquine (n = 37), intramuscular artesunate followed by mefloquine (n = 37), or intravenous quinine followed by pyrimethamine/sulfadoxine (n = 35). There were 9 deaths: 2 artemisinin, 4 artesunate and 5 quinine-treated children. There was no difference in fever clearance time, coma recovery, or length of hospital stay among the 3 groups. However, parasite clearance times were significantly faster in artemisinin and artesunate-treated patients than in those who received quinine (P children receiving these drugs had lower peripheral reticulocyte counts by day 5 of treatment than those in the quinine group (P = 0.011). No other adverse effect or toxicity was found. There was no treatment failure in these 2 groups, but 4 patients in the quinine group failed to clear their parasites within 7 d of starting treatment and required alternative antimalarial therapy. Artemisinin suppositories are easy to administer, cheap, and very effective for treating children with severe malaria. In rural areas where medical facilities are lacking these drugs will allow antimalarial therapy to be instituted earlier in the course of the disease and may therefore save lives.

Full Text Available Introduction: Permanent hearing loss and tinnitus as side-effects from treatment with the anticancer drug cisplatin is a clinical problem. Ototoxicity may be reduced by co-administration of an otoprotective agent, but the results in humans have so far been modest.Aim: The present preclinical in vivo study aimed to explore the protective efficacy of hydrogen (H2 inhalation on ototoxicity induced by intravenous cisplatin.Materials and Methods: Albino guinea pigs were divided into four groups. The Cispt (n = 11 and Cispt+H2 (n = 11 groups were given intravenous cisplatin (8 mg/kg b.w., injection rate 0.2 ml/min. Immediately after, the Cispt+H2 group also received gaseous H2 (2% in air, 60 min. The H2 group (n = 5 received only H2 and the Control group (n = 7 received neither cisplatin nor H2. Ototoxicity was assessed by measuring frequency specific ABR thresholds before and 96 h after treatment, loss of inner (IHCs and outer (OHCs hair cells, and by performing densitometry-based immunohistochemistry analysis of cochlear synaptophysin, organic transporter 2 (OCT2, and copper transporter 1 (CTR1 at 12 and 7 mm from the round window. By utilizing metabolomics analysis of perilymph the change of metabolites in the perilymph was assessed.Results: Cisplatin induced electrophysiological threshold shifts, hair cell loss, and reduced synaptophysin immunoreactivity in the synapse area around the IHCs and OHCs. H2 inhalation mitigated all these effects. Cisplatin also reduced the OCT2 intensity in the inner and outer pillar cells and in the stria vascularis as well as the CTR1 intensity in the synapse area around the IHCs, the Deiters' cells, and the stria vascularis. H2 prevented the majority of these effects.Conclusion: H2 inhalation can reduce cisplatin-induced ototoxicity on functional, cellular, and subcellular levels. It is proposed that synaptopathy may serve as a marker for cisplatin ototoxicity. The effect of H2 on the antineoplastic activity of

Full Text Available Acute headaches are responsible for a significant percentage of the case load at primary care units and emergency rooms in Brazil. Dipyrone (metamizol is easily available in these settings, being the most frequently used drug. We conducted a randomized, placebo-controlled, double-blind study to assess the effect of dipyrone in the acute treatment of episodic tension-type headache. Sixty patients were randomized to receive placebo (intravenous injection of 10 ml saline or 1 g dipyrone in 10 ml saline. We used seven parameters of analgesic evaluation. The patients receiving dipyrone showed a statistically significant improvement (P<0.05 of pain compared to placebo up to 30 min after drug administration. The therapeutic gain was 30% in 30 min and 40% in 60 min. The number of patients needed to be treated for at least one to have benefit was 3.3 in 30 min and 2.2 in 60 min. There were statistically significant reductions in the recurrence (dipyrone = 25%, placebo = 50% and use of rescue medication (dipyrone = 20%, placebo = 47.6% for the dipyrone group. Intravenous dipyrone is an effective drug for the relief of pain in tension-type headache and its use is justified in the emergency room setting.

8 healthy volunteers and 4 asplenic subjects, in whom autologous platelets had been labelled with radioactive sodium chromate, received intravenous infusions of isoprenaline in a dose of 0.03 ..mu..g x kg/sup -1/ x min/sup -1/ over a period of 6 min. In the former group these infusions caused a significant decrease in the concentration of labelled as well as unlabelled platelets in the peripheral blood. Body surface countings showed that a significant increase in the count rate over the spleen occurred concomitantly with the decrease in the circulating platelet-bound radioactivity (PBR). In the group of asplenic subjects no change in PBR occurred. It is concluded that adrenergic beta-receptor stimulation causes a transitory trapping of platelets in the exchangeable splenic platelet pool.

Intravenous Iron Carboxymaltose as a Potential Therapeutic in Anemia of Inflammation.

Directory of Open Access Journals (Sweden)

Niklas Lofruthe

Full Text Available Intravenous iron supplementation is an effective therapy in iron deficiency anemia (IDA, but controversial in anemia of inflammation (AI. Unbound iron can be used by bacteria and viruses for their replication and enhance the inflammatory response. Nowadays available high molecular weight iron complexes for intravenous iron substitution, such as ferric carboxymaltose, might be useful in AI, as these pharmaceuticals deliver low doses of free iron over a prolonged period of time. We tested the effects of intravenous iron carboxymaltose in murine AI: Wild-type mice were exposed to the heat-killed Brucella abortus (BA model and treated with or without high molecular weight intravenous iron. 4h after BA injection followed by 2h after intravenous iron treatment, inflammatory cytokines were upregulated by BA, but not enhanced by iron treatment. In long term experiments, mice were fed a regular or an iron deficient diet and then treated with intravenous iron or saline 14 days after BA injection. Iron treatment in mice with BA-induced AI was effective 24h after iron administration. In contrast, mice with IDA (on iron deficiency diet prior to BA-IA required 7d to recover from AI. In these experiments, inflammatory markers were not further induced in iron-treated compared to vehicle-treated BA-injected mice. These results demonstrate that intravenous iron supplementation effectively treated the murine BA-induced AI without further enhancement of the inflammatory response. Studies in humans have to reveal treatment options for AI in patients.

Acute post-partum anaemia can be associated with significant morbidity including a predisposition for postnatal depression. Lack of clear practice guidelines means a number of women are treated with multiple blood transfusions. Intravenous iron has the potential to limit the need for multiple blood transfusions but its role in the post-partum setting is unclear. IIBAPPA is a multi-centre randomised non-inferiority trial. Women with a primary post-partum haemorrhage (PPH) >1000 mL and resultant haemoglobin (Hb) 5.5-8.0 g/dL after resuscitation with ongoing symptomatic anaemia who are otherwise stable (no active bleeding) are eligible to participate. Patients with sepsis or conditions necessitating rapid Hb restoration are excluded. Eligible participants are randomised to receive a blood transfusion or a single dose of intravenous iron polymaltose calculated using the Ganzoni formula. Primary outcome measures include Hb, Ferritin and C-Reactive Protein levels on Day 7. Secondary outcomes evaluate (i) Hb, Ferritin and CRP levels on Day 14, 28, (ii) anaemia symptoms on Day 0, 7, 14 and 28 using structured health related quality of life questionnaires, (iii) treatment safety by assessing adverse reactions and infection endpoints and (iv) the quantitative impact of anaemia on breast feeding quality using a hospital designed questionnaire. If equivalence in Hb and ferritin levels, symptom scores and safety endpoints is demonstrated, intravenous iron may become the preferred treatment for women with acute post-partum anaemia to minimise transfusion reactions and costs.

However, successful venipuncture and intravenous cannulation are absolutely required for pediatric clinical risk management. This study assessed the success rate of venipuncture and intravenous cannulation when transmitted light was applied to the pediatric dorsum manus. The subjects included 100 young children who were scheduled for dental treatment or oral surgery under general anesthesia. Anesthesia was induced, and insertion of an intravenous catheter into the dorsum manus was attempted with or without using transmitted light. The patients were evaluated to determine whether the venipuncture was successful, and whether the intravenous cannulation of the external catheter was successful. The success rate of venipuncture was 100% when transmitted light was used, and 83% when the transmitted light was not used (P = 0.000016. In addition, the success rate of intravenous cannulation was 88% when transmitted light was used, and 55% when the transmitted light was not used (P = 0.0000002. The shape of the vein in the dorsum manus can be clearly recognized when transmitted light is used. The use of light significantly increased the success rate of intravenous cannulation, because it allowed direct confirmation of the direction to push the intravenous catheter forward. The use of transmitted light allows for more successful venipuncture and intravenous cannulation in young children.

Full Text Available Multimodal analgesia refers to the practice of combining multiple analgesic drug classes or techniques to target different points along the pain pathway. The objective of this work was to evaluate clinically if ketoprofen associated or not with intravenous or epidural morphine provided adequate postoperative analgesia in bitches undergoing ovariosalpingohysterectomy (OSH. Forty healthy female dogs, weighing 10.7±6.0 kg, sedated with acepromazine (0.05mg kg –1.iv, induced with propofol (5 mg.kg-1. iv and maintained with isoflurane anesthesia, were distributed into four groups of 10 animals each. After stabilization of inhalation anesthesia, the bitches in Miv and CMiv groups received 0.2 mg.kg-1 of morphine intravenously diluted in 10ml of saline; whereas Mep and CMep groups received 0.1mg.kg-1 of epidural morphine. Thirty minutes after premedication, 2.0mg.kg-1.im of ketoprofen was administered in groups CMiv and CMep. Heart and respiratory rate, systolic blood pressure, and rectal temperature were measured. The degree of analgesia was assessed by a blind study in the following 6 hours after surgery, using a descriptive scale and a scale composed by physiologic and behavioral parameters. An statistical analysis was performed using the Tukey-Kramer test and nonparametric Kruskal-Wallis test, with statistical significance of 5%. There was no important difference between the four groups regarding postoperative analgesia, heart and respiratory rate, systolic blood pressure and rectal temperature. According to the results it can be concluded that the use of ketoprofen associated with intravenous or epidural morphine provided adequate and safe analgesia in the first six hours of postoperative in bitches undergoing ovariohysterectomy, suggesting that there was no analgesic potentiation when both agents were combined.

The National Institute of Child Health and Human Development, American College of Obstetricians and Gynecologists, and Society for Maternal-Fetal Medicine have emphasized the need to promote vaginal delivery and have offered recommendations to safely prevent primary cesarean delivery. However, there has been limited discussion regarding management of intravenous fluids and other aspects of labor management that may influence mode of delivery. Therefore the aim of our study was to determine whether an intravenous fluid rate of 250 vs. 125 mL/h is associated with a difference in cesarean delivery rate. Searches were performed in MEDLINE, OVID, Scopus, ClinicalTrials.gov, the PROSPERO International Prospective Register of Systematic Reviews, Embase, Web of Science, and the Cochrane Library for randomized controlled trials. We included all randomized controlled trials comparing intravenous fluid rates of 250 vs. 125 mL/h in nulliparous women in spontaneous labor at term with singleton pregnancies at ≥36 weeks. Studies were included regardless of the type of intravenous fluids used and regardless of whether oral intake was restricted during labor. Studies including multiparous women or women whose labor was induced were excluded. The primary outcome was the incidence of cesarean delivery. We planned to assess a subgroup analysis according to type of fluids used and according to restriction of oral fluid intake. Seven trials including 1215 nulliparous women in spontaneous labor at term were analyzed; 593 (48.8%) in the 250 mL/h group, and 622 (51.2%) in the 125 mL/h group. Five studies used lactated Ringer's solution, one used normal saline in dextrose water, and in one study it was unclear which intravenous fluid was used. Women who received intravenous fluids at 250 mL/h had a significantly lower incidence of cesarean delivery for any indication (12.5 vs. 18.1%; RR 0.70, 95% CI 0.53-0.92; seven studies, 1215 participants; I 2 = 0%) and for dystocia (4.9 vs. 7.7%; RR

Intravenous ports are widely used for oncology patients. However, catheter fractures may lead to the need for re-intervention. We aimed to identify the risk factors associated with catheter fractures. Between January 1 and December 31, 2006, we retrospectively reviewed the clinical data and plain chest films of 1,505 patients implanted with an intravenous port at Chang Gung Memorial Hospital. Different vascular sites were compared using the chi-square or Fisher's exact test for categorical variables, and the t test was used for continuous variables with normal distribution; P port type Arrow French (Fr.) 8.1 (P port and catheter removal is recommended. Female gender, intravenous port implantation via the subclavian route, and the Arrow Fr. 8.1 port were found to be risk factors. Patients with these risk factors should be monitored closely to avoid catheter fractures.

Although the transurethral resection of bladder tumor (TURBT followed by intravesical chemotherapy is a conservative strategy for treatment of T1G3 bladder cancer, a relatively high risk of tumor recurrence and progression remains regarding the therapy. This study aimed to compare the efficacy of intravenous chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder cancer after TURBT surgery. Methods: We retrospectively reviewed the cases of 457 patients who were newly diagnosed with T1G3 bladder urothelial carcinoma between January 2009 and March 2014. After TURBT, 281 patients received intravesical chemotherapy alone, whereas 176 patients underwent intravesical chemotherapy in combination with intravenous chemotherapy. Tumor recurrence and progression were monitored periodically by urine cytology and cystoscopy in follow-up. Recurrence-free survival and progression-free survival of the two chemotherapy strategies following TURBT were analyzed. Univariable and multivariable Cox hazards analyses were performed to predict the prognostic factors for tumor recurrence and progression. Results: The tumor recurrence rate was 36.7% for patients who received intravesical chemotherapy alone after TURBT, compared with 19.9% for patients who received intravenous chemotherapy combined with intravesical chemotherapy after

To compare the pain reported by patients during the Essure Micro-Insert sterilization procedure using either intravenous conscious sedation or oral analgesia. Randomized, double-blind, placebo-controlled trial (Canadian Task Force classification I). Tertiary care ambulatory women's clinic. Eighty women of reproductive age women requesting permanent sterilization. Hysteroscopic placement of the Essure Micro-Insert permanent birth control system. Patients undergoing placement of the Essure Micro-Insert system for permanent contraception were randomized to receive either intravenous conscious sedation, oral analgesia, or placebo. During the procedure, pain scores were recorded using a visual analog scale. Patients in the oral analgesia group reported slightly more pain during insertion of the hysteroscope and placement of the second micro-insert; the groups were otherwise equivalent. They were also equivalent when all visual analog scale scores were combined. Oral analgesia is an effective method of pain control during placement of the Essure Micro-Insert permanent birth control system. Copyright © 2011 AAGL. Published by Elsevier Inc.

Gasoline, ingested intentionally or accidentally, is toxic. The majority of reported cases of gasoline intoxication involve oral ingestion or inhalation. Data are scarce on complications and outcomes following hydrocarbon poisoning by intravenous injection. Following a suicide attempt by intravenous self-injection of 10 ml of gasoline, a 26-year-old medical student was admitted to the intensive care unit (ICU) with hemoptysis, symptoms of acute respiratory failure, chest pain, and severe abdominal cramps. Gas exchange was severely impaired and a chest x-ray indicated chemical pneumonitis. Initial treatment consisted of mechanical ventilation, supportive hyperventilation, administration of nitrogen oxide (NO), and prednisone. Unfortunately, the patient developed multi-organ dysfunction syndrome (MODS) complicated by life-threatening severe vasoplegia within 24 hours after gasoline injection. High doses of vasopressors along with massive amounts of parenteral fluids were necessary. Despite fluid replacement, renal function worsened and required hemofiltration on 5 sequential days. After 12 days of intensive care management, the patient recovered completely and was discharged to a psychiatric care facility. Intravenous gasoline injection causes major injury to the lungs, the organ bearing the first capillary bed encountered. Treatment of gasoline poisoning is symptomatic because no specific antidote is available. Early and aggressive supportive care may be conducive to a favorable outcome with minimal residual pulmonary sequelae.

Full Text Available Peripheral nerve injury is a common and devastating complication after trauma and can cause irreversible impairment or even complete functional loss of the affected limb. While peripheral nerve repair results in some axonal regeneration and functional recovery, the clinical outcome is not optimal and research continues to optimize functional recovery after nerve repair. Cell transplantation approaches are being used experimentally to enhance regeneration. Intravenous infusion of mesenchymal stromal cells (MSCs into spinal cord injury and stroke was shown to improve functional outcome. However, the repair potential of intravenously transplanted MSCs in peripheral nerve injury has not been addressed yet. Here we describe the impact of intravenously infused MSCs on functional outcome in a peripheral nerve injury model. Rat sciatic nerves were transected followed, by intravenous MSCs transplantation. Footprint analysis was carried out and 21 days after transplantation, the nerves were removed for histology. Labelled MSCs were found in the sciatic nerve lesion site after intravenous injection and regeneration was improved. Intravenously infused MSCs after acute peripheral nerve target the lesion site and survive within the nerve and the MSC treated group showed greater functional improvement. The results of study suggest that nerve repair with cell transplantation could lead to greater functional outcome.

Full Text Available Opioids are the most available medicines to get rid of any general severe pain and avoiding of any deleterious sequential that can worsen patient outcomes. Rational prescription of opioid analgesics with respect to the possibility of abuse is a big concern in the medical care costs. Zabol, where is located in eastern part of Iran and has common border with Afghanistanhas the most opioid traffic in the region. In this study the rational prescription of parenteral opioid in Amir-al-Momenin general hospital was investigated. A retrospective drug utilization review was performed on 509 in-patients who received parenteral opioids including Morphine, Pethidin, Pentazocin, Fentanyl, Alfentanil, Sufentanil and Methadone from March 21sttoSeptember 23rd, 2011. Multivariate conditional regression modeling was used to determine independent predictors for daily parenteral opioid consumption. Total daily parenteral opioid consumption was 38.63 DDDs/100bed-days for Morphine, Pethidine and Pentazocin and 84564.78 PFEQs/100bed-days for Fentanyl, Alfentanil and Sufentanil and 766 mg for Methadone. Pethidine was the most frequently prescribed parenteral opioid. Most patients who were prescribed by the intramuscular routes, ordered PRN. Daily parenteral opioid consumption was the highest in the emergency ward whereas it was considered as the lowest in the intensive care unit[ICU]. According to our findings, total daily parenteral opioid consumption was almost high in Amir-al-Momenin Hospital. Unlike to some relevant factors that can effect on the consumption of analgesic opioids like gender, age, drug-drug interaction and etc, we found no rational prescription and consumption in the mentioned hospital.

The use of peripheral intravenous cannulae is common in newborn babies. Many of them require an intravenous line only for medications and not for fluid. Currently there is little uniformity in methods used to maintain cannula patency. The object of this review was to determine which method was better for maintaining intravenous lines used in neonates for intravenous medication only: intermittent flushing or continuous infusion We searched The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2004), CINAHL (from 1982 to June 2004) and MEDLINE (from 1966 to June 2004) . Randomised controlled trials comparing continuous infusion to intermittent flushing to maintain patency of intravenous cannulas. Units of randomisation might include individual catheters or individual babies. Three reviewers independently assessed trial quality and extracted data. Two studies were eligible for inclusion. In one study only one of our primary outcomes was available: the duration of cannula patency for the first cannula used per infant was slightly longer in the continuous infusion group, but not significantly so, with a mean difference of -4.3 hours (95% CI -18.2 to 9.7). In the second study, only one of our primary outcomes was available: the mean (SD) number cannulas used per infant in the first 48 hours was less in the intermittent flush group with a mean difference of -0.76 cannulas (95% CI -1.37 to -0.15). No results were available for any of our other primary outcomes: in the published report, results were reported per catheter rather than per infant, a number of infants received more than one intravenous catheter (39 infants received an unknown number of catheters). The overall duration of cannula patency was significantly longer in the intermittent flush group with a mean duration of patency in the intermittent flush group of 2.1 days (SD 1.0) compared with the continuous infusion group where the mean duration of patency was 1.0 days (SD 0

Full Text Available Background/Aim. Intravenous immunoglobulin is a blood product made of human polyclonal immunoglobulin G. The mode of action of intravenous immunoglobulin is very complex. It is indicated in treatment of neonatal immune thrombocytopenia and haemolytic disease of the newborn. The aim of the study was to present our experience in the use of intravenous immunoglobulin in a group of term neonates. Methods. We analysed all relevant clinical and laboratory data of 23 neonates who recieved intravenous immunoglobulin during their hospitalization in Neonatal Intensive Care Unit of Mother and Child Health Care Institute over a five year period, from 2006. to 2010. Results. There were 11 patients with haemolytic disease of the newborn and 12 neonates with immune thrombocytopenia. All of them recieved 1-2 g/kg intravenous immunoglobulin in the course of their treatment. There was no adverse effects of intravenous immunoglobulin use. The use of intravenous immunoglobulin led to an increase in platelet number in thrombocytopenic patients, whereas in those with haemolytic disease serum bilirubin level decreased significantly, so that some patients whose bilirubin level was very close to the exchange transfusion criterion, avoided this procedure. Conclusion. The use of intravenous immunoglobulin was shown to be an effective treatment in reducing the need for exchange transfusion, duration of phototherapy and the length of hospital stay in neonates with haemolytic disease. When used in treatment of neonatal immune thrombocytopenia, it leads to an increase in the platelet number, thus decreasing the risk of serious complications of thrombocytopenia.

Anemia affects up to 42% of gravidas. Neonatal iron deficiency is associated with low birth weight, delayed growth and development, and increased cognitive and behavioral abnormalities. While oral iron is convenient, up to 70% report significant gastrointestinal toxicity. Intravenous iron formulations allowing replacement in one visit with favorable side-effect profiles decrease rates of anemia with improved hemoglobin responses and maternal fetal outcomes. Seventy-four oral iron-intolerant, second- and third-trimester iron-deficient gravidas were questioned for oral iron intolerance and treated with intravenous iron. All received 1000 mg of low-molecular-weight iron dextran in 250 mL normal saline. Fifteen minutes after a test dose, the remainder was infused over the balance of 1 hour. Subjects were called at 1, 2, and 7 days to assess delayed reactions. Four weeks postinfusion or postpartum, hemoglobin levels and iron parameters were measured. Paired t test was used for hemoglobin and iron; 58/73 women were questioned about interval growth and development of their babies. Seventy-three of 74 enrolled subjects completed treatment. Sixty had paired pre- and posttreatment data. The mean pre- and posthemoglobin concentrations were 9.7 and 10.8 g/dL (P iron deficiency anemia. Intravenous iron has less toxicity and is more effective, supporting moving it closer to frontline therapy. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background Cardiac surgery is a major consumer of blood products, and hemodilution increases transfusion requirements during cardiac surgery under CPB. As intraoperative parenteral fluids contribute to hemodilution, we evaluated the hypothesis that intraoperative fluid restriction reduces packed red-cell (PRC use, especially in transfusion-prone adults undergoing elective cardiac surgery. Methods 192 patients were randomly assigned to restrictive (group A, 100 pts, or liberal (group B, 92 pts intraoperative intravenous fluid administration. All operations were conducted by the same team (same surgeon and perfusionist. After anesthesia induction, intravenous fluids were turned off in Group A (fluid restriction patients, who only received fluids if directed by protocol. In contrast, intravenous fluid administration was unrestricted in group B. Transfusion decisions were made by the attending anesthesiologist, based on identical transfusion guidelines for both groups. Results 137 of 192 patients received 289 PRC units in total. Age, sex, weight, height, BMI, BSA, LVEF, CPB duration and surgery duration did not differ between groups. Fluid balance was less positive in Group A. Fewer group A patients (62/100 required transfusion compared to group B (75/92, p Conclusions Our data suggest that fluid restriction reduces intraoperative PRC transfusions without significantly increasing postoperative transfusions in cardiac surgery; this effect is more pronounced in transfusion-prone patients.

Complexity of intravenous iron nanoparticle formulations: implications for bioequivalence evaluation.

Science.gov (United States)

Pai, Amy Barton

2017-11-01

Intravenous iron formulations are a class of complex drugs that are commonly used to treat a wide variety of disease states associated with iron deficiency and anemia. Venofer® (iron-sucrose) is one of the most frequently used formulations, with more than 90% of dialysis patients in the United States receiving this formulation. Emerging data from global markets outside the United States, where many iron-sucrose similars or copies are available, have shown that these formulations may have safety and efficacy profiles that differ from the reference listed drug. This may be attributable to uncharacterized differences in physicochemical characteristics and/or differences in labile iron release. As bioequivalence evaluation guidance evolves, clinicians should be educated on these potential clinical issues before a switch to the generic formulation is made in the clinical setting. © 2017 New York Academy of Sciences.

We wanted to evaluate the usefulness of modified intravenous analgesia for the management of pain during uterine artery embolization for leiomyomata. Between April 2004 and July 2004, 15 patients with symptomatic fibroids underwent uterine artery embolization and pain management. Except the three patients for whom the Visual Analogue Scale (VAS) score was not obtained, twelve patients were included in this study. For pain management, epidural PCA (Patient Controlled Analgesia) was used in two patients, intravenous PCA was used in two patients and modified intravenous analgesia injection was used in eight patients. For all the patients, we used the 2.8 Fr coaxial microcatheter and 500-710 μ m PVA particles for the embolic materials. The protocol of the modified intravenous analgesia injection was as follow, 1) prior to femoral artery puncture, 30 mg of ketorolac tromethamine (Tarasyn)was injected via an intravenous route. 2) At the time that the one side uterine artery embolization was finished, normal saline mixed 150 mg meperidine (Demerol) was administered through the side port of the intravenous line that was used for hydration. 3) Additional ketorolac tromethamine 30 mg was injected after 6 hour. The VAS score and side effects were then checked. After 12 hours, the VAS score was rechecked. If the VAS score was above 4, this was considered as failure of pain management. The VAS scores, complications and side effects for the modified intravenous analgesia injection were compared with that of IV PCA and epidural PCA. The average VAS score of the modified intravenous analgesia injection, intravenous PCA and epidural PCA was 1.4, 1 and 0, respectively; the number of additional intramuscular injections of analgesia was 0.5, 0.5 and 0, respectively. All the patients who underwent epidural PCA had back pain at the puncture site and 1 patient who underwent modified intravenous analgesia injection experienced mild dyspnea, but they easily recovered with such

We wanted to evaluate the usefulness of modified intravenous analgesia for the management of pain during uterine artery embolization for leiomyomata. Between April 2004 and July 2004, 15 patients with symptomatic fibroids underwent uterine artery embolization and pain management. Except the three patients for whom the Visual Analogue Scale (VAS) score was not obtained, twelve patients were included in this study. For pain management, epidural PCA (Patient Controlled Analgesia) was used in two patients, intravenous PCA was used in two patients and modified intravenous analgesia injection was used in eight patients. For all the patients, we used the 2.8 Fr coaxial microcatheter and 500-710 {mu} m PVA particles for the embolic materials. The protocol of the modified intravenous analgesia injection was as follow, 1) prior to femoral artery puncture, 30 mg of ketorolac tromethamine (Tarasyn)was injected via an intravenous route. 2) At the time that the one side uterine artery embolization was finished, normal saline mixed 150 mg meperidine (Demerol) was administered through the side port of the intravenous line that was used for hydration. 3) Additional ketorolac tromethamine 30 mg was injected after 6 hour.

The need for greater clarity about the effects of 5-HT(3) receptor antagonists on cardiac repolarization is apparent in the changing product labeling across this therapeutic class. This study assessed the repolarization effects of granisetron, a 5-HT(3) receptor antagonist antiemetic, administered intravenously and by a granisetron transdermal system (GTDS). In a parallel four-arm study, healthy subjects were randomized to receive intravenous granisetron, GTDS, placebo, or oral moxifloxacin (active control). The primary endpoint was difference in change from baseline in mean Fridericia-corrected QT interval (QTcF) between GTDS and placebo (ddQTcF) on days 3 and 5. A total of 240 subjects were enrolled, 60 in each group. Adequate sensitivity for detection of QTc change was shown by a 5.75 ms lower bound of the 90% confidence interval (CI) for moxifloxacin versus placebo at 2 hours postdose on day 3. Day 3 ddQTcF values varied between 0.2 and 1.9 ms for GTDS (maximum upper bound of 90% CI, 6.88 ms), between -1.2 and 1.6 ms for i.v. granisetron (maximum upper bound of 90% CI, 5.86 ms), and between -3.4 and 4.7 ms for moxifloxacin (maximum upper bound of 90% CI, 13.45 ms). Day 5 findings were similar. Pharmacokinetic-ddQTcF modeling showed a minimally positive slope of 0.157 ms/(ng/mL), but a very low correlation (r = 0.090). GTDS was not associated with statistically or clinically significant effects on QTcF or other electrocardiographic variables. This study provides useful clarification on the effect of granisetron delivered by GTDS on cardiac repolarization. ©2012 AACR.

Low-dose ketamine has been used perioperatively for pain control and may be a useful adjunct to intravenous (IV) opioids in the control of acute pain in the emergency department (ED). The aim of this study was to determine the effectiveness of low-dose ketamine as an adjunct to morphine versus standard care with morphine alone for the treatment of acute moderate to severe pain among ED patients. A double-blind, randomized, placebo-controlled trial with three study groups was conducted at a large, urban academic ED over a 10-month period. Eligible patients were 18 to 65 years old with acute moderate to severe pain (score of at least 5 out of 10 on the numerical pain rating scale [NRS] and pain duration ketamine (group 1), or 3) morphine and 0.3 mg/kg ketamine (group 2). Participants were assessed at 30, 60, and 120 minutes after study medication administration and received rescue analgesia as needed to target a 50% reduction in pain. The primary outcome measure of pain relief, or pain intensity reduction, was derived using the NRS and calculated as the summed pain-intensity (SPID) difference over 2 hours. The amount and timing of rescue opioid analgesia was evaluated as a secondary outcome. The occurrence of adverse events was also measured. Sixty patients were enrolled (n = 20 in each group). There were no differences between study groups with respect to age, sex, race/ethnicity, preenrollment analgesia, or baseline NRS. Over the 2-hour poststudy medication administration period, the SPIDs were higher (greater pain relief) for the ketamine study groups than the control group (standard care 4.0, interquartile range [IQR] = 1.8 to 6.5; group 1 7.0, IQR = 4.3 to 10.8; and group 2 7.8, IQR = 4.8 to 12.8; p ketamine groups were similar (p pain intensity up to 2 hours, whereas group 1 was similar to standard care by 2 hours. Similar numbers of patients received rescue analgesia: standard care group, seven of 20, 35%; group 1, four of 20, 20%; and group 2, four of 20, 20

Objective was to assess the effect of different doses of tramadol when added to lignocaine during intravenous regional anesthesia (IVRA). Sixty patients, scheduled for hand surgery under IVRA in King Fahd University Hospital, Al-Khobar, Saudi Arabia from January 2006 to January 2007 were randomly allocated into 3 groups (20 patients each) in a double blind controlled study. All patients received 0.5% lignocaine, 40ml plus 2ml of a study solution containing either isotonic saline (control group), or tramadol 50mg (group T50) or tramadol100mg (group T100). Hemodynamic changes, sensory and motor block onset and recovery time, tourniquet tolerance time, the quality of intraoperative anesthesia and the duration of postoperative analgesia were assessed. All patients 20 in each group completed the study period. Patients who received tramadol had earlier onset of sensory block (5.2+-1.2; 4.9+-1.2 min in the T50; and T100 groups) compared with the control group (7.6+-1.4 min). Patients who received 100mg of tramadol had better tolerance of tourniquet (p=0.011), and less intraoperative fentanyl supplementation (p=0.042). They had also a longer time to the first postoperative analgesic request (p=0.001) compared with the control group. Tramadol 100 mg is a beneficial additive to lignocaine for IVRA since it shortened the onset of sensory block, enhanced the tourniquet tolerance and improved the perioperative analgesia. (author)

We wanted to assess the usefulness of MRCP after intravenous morphine administration in the evaluation of the hepatopancreatic pancreatico-biliary ductal system. We studied 15 patients who were suspected of having disease of hepatopancreatic ductal system and they did not have any obstructive lesion on ultrasonography and/or CT. MRCP was acquired before and after morphine administration (0.04 mg/kg, intravenously). Three radiologists scored the quality of the images of the anatomic structures in the hepatopancreatic ductal system. We directly compared the quality of the images obtained with using the two methods and the improvement of the artifacts by pulsatile vascular compression. The MRCP images obtained after intravenous morphine administration were better than those obtained before morphine administration for visualizing the hepatopancreatic ductal system. On direct comparison, the MRCP images obtained after morphine administration were better in 12 cases, equivocal in two cases, and the images before morphine administration were better in only one case. In three patients, MRCP before morphine injection showed signal loss at the duct across the pulsatile hepatic artery. In two of three patients, MRCP after morphine injection showed no signal loss in this ductal area. MRCP after intravenous morphine administration enables physicians to see the hepatopancreatic ductal system significantly better and the artifacts caused by pulsation of the hepatic artery can be avoided

Imatinib, a tyrosine kinase inhibitor, has been shown to restore blood-brain barrier integrity and reduce infarct size, haemorrhagic transformation and cerebral oedema in stroke models treated with tissue plasminogen activator. We evaluated the safety of imatinib, based on clinical and neuroradiological data, and its potential influence on neurological and functional outcomes. A phase II randomized trial was performed in patients with acute ischaemic stroke treated with intravenous thrombolysis. A total of 60 patients were randomly assigned to four groups [3 (active): 1 (control)]; the active treatment groups received oral imatinib for 6 days at three dose levels (400, 600 and 800 mg). Primary outcome was any adverse event; secondary outcomes were haemorrhagic transformation, cerebral oedema, neurological severity on the National Institutes of Health Stroke Scale (NIHSS) at 7 days and at 3 months and functional outcomes on the modified Rankin scale (mRS). Four serious adverse events were reported, which resulted in three deaths (one in the control group and two in the 400-mg dose group; one patient in the latter group did not receive active treatment and the other received two doses). Nonserious adverse events were mostly mild, resulting in full recovery. Imatinib ameliorated neurological outcomes with an improvement of 0.6 NIHSS points per 100 mg imatinib (P = 0.02). For the 800-mg group, the mean unadjusted and adjusted NIHSS improvements were 4 (P = 0.037) and 5 points (P = 0.012), respectively, versus controls. Functional independence (mRS 0-2) increased by 18% versus controls (61 vs. 79; P = 0.296). This phase II study showed that imatinib is safe and tolerable and may reduce neurological disability in patients treated with intravenous thrombolysis after ischaemic stroke. A confirmatory randomized trial is currently underway. © 2016 The Authors. Journal of Internal Medicine published by John Wiley & Sons Ltd on behalf of Association for Publication of The

K-edge digital subtraction angiography (KEDSA), a recently developed synchrotron-based technique, utilizes monochromatic radiation and allows acquisition of high-quality angiography images after intravenous administration of contrast agent. We tested KEDSA for its suitability for intravenous cerebral angiography in an animal model. Adult male New Zealand rabbits were subjected to either angiography with conventional x-ray equipment or synchrotron-based intravenous KEDSA, using an iodine-based contrast agent. Angiography with conventional x-ray equipment after intra-arterial administration of contrast agent demonstrated the major intracranial vessels but no smaller branches. KEDSA was able to visualize the major intracranial vessels as well as smaller branches in both radiography mode (planar images) and tomography mode. Visualization was achieved with as little as 0.5 ml kg -1 of iodinated contrast material. We were able to obtain excellent visualization of the cerebral vasculature in an animal model using intravenous injection of contrast material, using synchrotron-based KEDSA

Intravenous thrombolysis with alteplase (actilise was carried in 300 patients (188 men and 112 women aged 21 to 79 years (mean age 59.8±13.7 years who had ischemic stroke (IS. Significant positive changes (a neurological deficit decrease on the NIHSS score by ≥ 4 points were observed in 67.3% of cases; mortality was 6.7%. Hemorrhagic events as asymptomatic hemorrhagic transformations were found in 19.3% of cases with the neurological disorders being progressive in 4.6%. Recanalization of internal carotid artery occlusion was recorded only in 24.0% of the patients and that of occlusion of the proximal segments of the middle cerebral artery was in 50.1%. Examples of effective intravenous thrombolysis in IS in the carotid and vertebrobasilar beds are given. Whether intravenous thrombolysis can be more extensively used in IS is discussed.

Adequate pain management following day-case surgery allows early ambulation of patients. In this study, we aimed to compare postoperative analgesic efficacy of intravenous (iv) dexketoprofen vs. iv paracetamol following day-case operative hysteroscopy. One hundred and fourteen American Society of Anesthesiologists (ASA) I-II patients scheduled for day-case operative hysteroscopy were recruited and randomized to three groups in the study. Group D received 50 mg iv dexketoprofen trometamol, Group P 1000 mg iv paracetamol and Group C normal saline solution. Visual Analogue Scale (VAS) pain intensity, pain relief, sedation, nausea-vomiting, other side effects, and additional opioid analgesic requirement were noted at postoperative 15 minutes (min), 30 min, 1 hour (h), 2 h, and 3 h. Patients with VAS>=40 mm received meperidine 0.25 mg/kg as rescue analgesic medication. VAS scores at 15 min, 30 min, 1 h, and 2 h were significantly lower in Group D compared to Group C. VAS scores at 15 min and 30 min were significantly lower in Group D compared to Group P. The percentages of patients who required opioid treatment were 34%, 60%, and 63% in Groups D, P and C, respectively (pdexketoprofen has superior efficacy for postoperative pain management following day-case operative hysteroscopy when compared with paracetamol and placebo.

Nurses noted that the rate of phlebitis was high when intravenous amiodarone was infused via a peripheral site. Hospital policy recommends a central vascular catheter, but this method is often not feasible because the drug is administered in emergent situations for short periods. To determine the rate and severity of phlebitis in patients given peripherally infused amiodarone. The literature, policy, and procedures for administration of amiodarone were reviewed; the pharmacy was consulted; and a data collection tool was developed. The tool was pilot tested and revised, and face validation was established. Data were collected during a 6-month period. A convenience sample was used. The study included a total of 12 patients. Each new infusion of intravenous amiodarone was considered a separate occurrence, for a total of 24 infusions. Various grades of phlebitis developed in 8 patients (67%). Phlebitis developed at 12 of the 24 infusion sites (50%). Patients receiving peripherally infused amiodarone are at high risk for phlebitis. This complication may lead to infection, additional medical intervention, delay in treatment, and prolonged hospitalization.

To evaluate whether the use of intravenous immunoglobulin in newborn infants with isoimmune hemolytic jaundice due to Rh and ABO incompatibility is an effective treatment in reducing the need for exchange transfusion. This study included all direct Coombs' test positive Rh and ABO isoimmunized babies, who admitted in the Neonatal Intensive Care Unit of Ghaem Hospital of Mashhad University of Medical Sciences, Iran, from October 2003 to October 2004. Significant hyperbilirubinemia was defined as rising by >or=0.5 mg/dl per hour. Babies were randomly assigned to received phototherapy with intravenous immunoglobulin (IVIg) 0.5 g/kg over 4 hours, every 12 hours for 3 doses (study group) or phototherapy alone (control group). Exchange transfusion was performed in any group if serum bilirubin exceeded >or=20mg/dl or rose by >or=1mg/dl/h. A total of 34 babies were eligible for this study (17 babies in each group). The number of exchange transfusion, duration of phototherapy and hospitalization days, were significant shorter in the study group versus control group. When we analyzed the outcome results in ABO and Rh hemolytic disease separately, the efficacy of IVIg was significantly better in Rh versus ABO isoimmunization. Late anemia was more common in the IVIg group 11.8% versus 0%, p=0.48. Adverse effects were not observed during IVIg administration. Administration of IVIg to newborns with significant hyperbilirubinemia due to Rh hemolytic disease reduced the need for exchange transfusion but in ABO hemolytic disease there was no significant difference between IVIg and double surface blue light phototherapy.

To identify the risk factors leading to catheter malfunction. Reliable venous access is crucial for cancer patients. Malfunction of intravenous ports may lead to discontinuation of treatment and repeated interventions. We retrospectively reviewed the independent risk factors for catheter malfunction among patients receiving intravenous port implantations. A total of 1508 procedures were included from the calendar year 2006, and clinical data and chest plain films were analyzed. The patients were followed-up until June 30, 2010. For patients still alive, the last outpatient follow-up date was considered as the end point. For the remaining patients, the date of death or discharge against advice was considered as the end points. The risk factors for catheter malfunction were then evaluated. The intervention-free periods of the malfunction group and nonmalfunction group were 317 and 413 days, respectively. Statistical analyses showed that the Nut-Catheter Angle was the only risk factor for catheter malfunction (P = 0.001). A logistic model also confirmed that the Nut-Catheter Angle was the only risk factor for catheter malfunction (P risk for catheter malfunction. Catheter impingement caused by inadequate pocket creation and port implantation lead to compromised catheter lumen and difficulty flushing. The possibility of retained blood and medications increased thin thrombotic biofilm formation and medication precipitation. Catheter malfunctions can be avoided by using proper surgical techniques and adequate maintenance.

In a prospective randomised study, we investigated the influence of the route of administration of radioiodide on dosimetry and therapy outcome. Fifty-four patients suffering from Graves' disease (GD) and 60 patients with unifocal autonomy (UA) participated in the study and were randomly treated with either orally or intravenously administered radioiodide. Pretherapeutic dosimetry was based on single uptake measurements with a calibrated uptake probe system. The radioiodine kinetics during hospitalisation was assessed by daily bedside uptake measurements. Therapeutic dose was determined by half-life and thyroid uptake at the time of discharge using the same uptake probe as for the radioiodine test. No improvement in accuracy of dosimetry was achieved when radioiodide was administered intravenously. Mean therapeutic doses were identical following intravenous or oral administration. Variation in the achieved dose was slightly higher in the patients receiving oral administration, this being attributable to larger deviations in discrete activities of the capsules administered as compared with the values determined by dosimetry. No differences according to treatment modality were found with regard to therapeutic outcome. Eighty-seven patients attended 6-month follow-up after therapy. In the UA group, successful treatment, defined as a normal or elevated TSH level, was observed in 94% of patients after oral administration and in 80% after intravenous administration; corresponding figures in the GD group were 68% and 65%. The causes of individual differences between targeted and therapeutically achieved doses remain undetermined. Variations in the bioavailability of radioiodide or other parameters affecting thyroid status may be involved, and further investigations are needed to clarify this. (orig.)

Prior to the HT, mean pulmonary artery pressure (mPAP was 32-56 mmHg. In all cases, the hemodynamic study demonstrated PH reactivity (positive vasodilator test with nitric oxide. All 5 patients developed RVD with hemodynamic instability immediately after the HT, despite the administration of nitric oxide from the time of intubation prior to the implant, optimal medical treatment in all cases, and a ventricular assist in 2 cases. In all patients, IV sildenafil was initiated at 10 mg/8 h for 48 h and was subsequently increased to 20 mg/8 h. in its oral formulation until discharge from the hospital. The change in pulmonary pressure was assessed using a Swan-Ganz catheter. Ventricular function was assessed using echocardiography. Length of stay in the Resuscitation Unit and mid-term survival were also assessed. Average time of extracorporeal circulation was 200 ± 110 min and organ ischemic time was 210 ± 95 min. All of the patients demonstrated pulmonary and systemic hemodynamic improvement, as well as recovery of right ventricular function after completing the treatment with IV sildenafil. The stay in the Resuscitation Unit lasted 3-25 days. All the patients were discharged from hospital with no mortality to date. Intravenous sildenafil improves right ventricle hemodynamics associated with pulmonary hypertension post-HT. Prophylactic prevention with this drug could be indicated for patients with reactive PH who are about to receive a transplant.

To evaluate the effectiveness and safety of a single intravenous dose of tranexamic acid in order to reduce blood loss in total knee replacement. Prospective observational study of the administration of tranexamic acid in patients undergoing primary total knee arthroplasty from November 2013 to February 2015, in which an autologous blood recovery system was used. The study included 98 patients, distributed into two groups of 49 patients according to whether or not they received intravenous tranexamic acid. The primary endpoint was the number of patients requiring autologous transfusion from the recovery system autologous blood recovery system. No drop-outs were recorded during follow-up. There were no significant differences between groups as regards the preoperative and hospital variables. The mean preoperative haemoglobin and haematocrit at 24 and 48 hours postoperatively were similar in both groups. The average volume of bleeding in the autologous blood recovery system and estimated average blood loss was lower in patients who had been administered tranexamic acid, with significant differences. No patients in the group that was administered tranexamic acid required blood autotransfusion. The transfusion rate was zero in the two groups. No adverse events related to the administration of tranexamic acid were recorded. Intravenous administration of tranexamic acid, according to the described protocol, has presented a non-autotransfusion or allo-transfusion rate of 100%, with no increased incidence of thrombotic events. Thus, its use in this group of patients is recommended. The indication should be individualized, its use justified in the patient medical records, and informed consent is mandatory.

Sonic hedgehog (Shh) is a glycoprotein molecule that upregulates the transcription factor Gli1. The Shh protein plays a critical role in the proliferation of endogenous neural precursor cells when directly injected into the spinal cord after a spinal cord injury in adult rodents. Small-molecule agonists of the hedgehog (Hh) pathway were used in an attempt to reproduce these findings through intravenous administration. The expression of Gli1 was measured in rat spinal cord after the intravenous administration of an Hh agonist. Ten adult rats received a moderate contusion and were treated with either an Hh agonist (10 mg/kg, intravenously) or vehicle (5 rodents per group) 1 hour and 4 days after injury. The rats were killed 5 days postinjury. Tissue samples were immediately placed in fixative. Samples were immunohistochemically stained for neural precursor cells, and these cells were counted. Systemic dosing with an Hh agonist significantly upregulated Gli1 expression in the spinal cord (p < 0.005). After spinal contusion, animals treated with the Hh agonist had significantly more nestin-positive neural precursor cells around the rim of the lesion cavity than in vehicle-treated controls (means +/- SDs, 46.9 +/- 12.9 vs 20.9 +/- 8.3 cells/hpf, respectively, p < 0.005). There was no significant difference in the area of white matter injury between the groups. An intravenous Hh agonist at doses that upregulate spinal cord Gli1 transcription also increases the population of neural precursor cells after spinal cord injury in adult rats. These data support previous findings based on injections of Shh protein directly into the spinal cord.

Since its introduction in 1924, oral cholecystography has been used as a screening method in the diagnosis of the gallbladder disease. Recently, intravenous cholangiography has become a most valuable method in the diagnosis of biliary tract pathology because of its advantage of simultaneous visualization of the gallbladder and bile ducts in a short time. However, opinions vary considerably as to the significance of nonvisualization of the gallbladder with oral cholecystography. In attempt to evaluate how much intravenous cholangiography does contribute to the diagnosis in the cases that the gallbladder cannot be opacified or can only faintly visualized by the oral method, we have made a clinical observation in 168 patients, in whom intravenous cholangiography had been performed within a week following oral cholecystography, at Korea General Hospital during the last three years from January 1969 to December 1971. The results obtained are summarized as follows; 1. The results of oral cholecystography in 168 cases were as follow; well opacification of the gallbladder in 10 cases, faint opacification in 46 cases and nonopacification in 112 cases. 2. In 37.5% (42 cases) of 112 gallbladder not opacified by the oral method, the gallbladder was subsequently opacified by the intravenous method, and 11.6% (14 cases) turned out to be normal when examined by the intravenous method. 3. Further demonstration of abnormalities could be obtained with the aid intravenous cholangiography in 28 cases (16.6%); cholelithiasis in 12 cases and choledocholithiasis in 16 cases. 4. In every cases of 14 patients whose gallbladder were virtually not opacified by both oral and intravenous methods bit the common bile ducts could be opacified by intravenous cholangiography, definite abnormalities were identified in the gallbladder at surgery

Full Text Available Background and Objective. Vitamin C has antioxidant, neuroprotective, and neuromodulating effects. Recently, it showed antinociceptive effect as a result of the antioxidant properties. Therefore, we designed this study to assess the effect of intravenous vitamin C on opiate consumption and pain in patients undergoing laparoscopic colectomy. Methods. A total of 100 patients were enrolled and allocated to receive 50 mg/kg vitamin C or placebo by intravenous infusion immediately after induction of anesthesia. Morphine consumption and scores of pain were assessed at 2, 6, and 24 h after completion of surgery. Results. There were 97 patients included in the analysis. Patients who received vitamin C had higher plasma concentrations of vitamin C at the end of surgery, significantly lower morphine consumption at the 2 h after end of surgery, and significantly lower pain scores at rest during first 24 h postoperatively. There was no significant difference between groups in side effects, fatigue score, or pain score during cough. Conclusion. This study shows high dose vitamin C infusion decreased postoperative pain during the first 24 h and reduced morphine consumption in the early postoperative period. Additional research needed to examine whether higher doses of vitamin C and longer infusion times can amplify these effects.

Purpose: We performed this double-blinded, placebo-controlled study to determine the safety and efficacy of L-alanyl-L-glutamine in the prevention of mucositis in patients with head-and-neck cancer. Methods and Materials: Thirty-two patients with head-and-neck cancer were treated with chemoradiotherapy (CRT) (radiotherapy daily up to 70 Gy plus cisplatin/5-fluoruracil once a week) and were asked to participate. Twenty-nine patients received the CRT schedule and were double-blindly assigned to receive either intravenous L-alanyl-L-glutamine 0.4 g/kg weight/day or an equal volume of saline (placebo) during chemotherapy days. Results: Fourteen patients received L-alanyl-L-glutamine and 15 received placebo. Mucositis was assessed by the Objective Mucositis Score (OMS) and the World Health Organization (WHO) grading system. There was a significant difference in incidence of mucositis developed in patients receiving placebo compared with those who received L-alanyl-L-glutamine (p = 0.035). The number of patients with severe objective mucositis (OMS >1.49) was higher in the placebo group compared with the L-alanyl-L-glutamine group (67% vs. 14%, p 0.007). L-alanyl-L-glutamine patients experienced less pain (three highest Numeric Rating Scale scores of 1.3/10 vs. 6.3/10 respectively, p = 0.008) and need for feeding tubes (14% vs. 60% respectively, p = 0.020) compared with placebo patients. No adverse effects related to the drug or the infusions were noted in either group. Conclusion: For patients with head-and-neck cancer receiving CRT, intravenous L-alanyl-L-glutamine may be an effective preventive measure to decrease the severity of mucositis

Results of 351 intravenous digital subtraction angiographs (AN) of transplanted kidneys emphasized reliability of this examination for detection of renal artery stenosis. A prospective study of 219 patients (188 interpretable AN) showed significant stenosis of grafted artery in 22% of cases: 17% of the 126 patients with normal blood pressure and 34% of the 62 cases of hypertension. Digital subtraction allows, with a single injection, assessment of renal artery, nephrogram and excretory cavities, but it is not a substitute for conventional intravenous urography 1 to 2 months after grafting [fr

The aim of this study was to understand technology and system characteristics that contribute to nurses' ratings of trust in a smart intravenous pump. Nurses' trust in new technologies can influence how technologies are used. Trust in technology is defined as a person's belief that a technology will not fail them. Potential outcomes of trust in technology are appropriate trust, overtrust, distrust, and mistrust. Trust in technology is also related to several use-specific outcomes, including appropriate use and inappropriate use such as overreliance, disuse or rejection, or misuse. Understanding trust in relation to outcomes can contribute to designs that facilitate appropriate trust in new technologies. A survey was completed by 391 nurses a year after the implementation of a new smart intravenous pump. The survey assessed trust in the intravenous pump and other elements of the sociotechnical system, individual characteristics, technology characteristics, and organizational characteristics. Results show that perceptions of usefulness, safety, ease of use, and usability are related to ratings of trust in smart intravenous pumps. Other work systemfactors such as perception of work environment, age, experience, quality of work, and perception of work performance are also related to ratings of trust. Nurses' trust in smart intravenous pumps is influenced by both characteristics of the technology and the sociotechnical system. Findings from this research have implications for the design of future smart intravenous pumps and health systems. Recommendations for appropriately trustworthy smart intravenous pumps are discussed. Findings also have implications for how trust in health technologies can be measured and conceptualized in complex sociotechnical systems.

Full Text Available Objective　To investigate the role of dexmedetomidine in stress control in moderate and severe traumatic brain injury (TBI and its influence on neuroendocrine system. Methods　Ninety moderate or severe TBI patients (GCS 6-13 were admitted to ICU from May 2009 to January 2012, and they were divided into three groups according to the order of admission. Patients in group A (n=32 received 0.5-1.0μg/kg dexmedetomidine within 30min, maintained with 0.2-0.6μg/(kg.h dexmedetomidine for 24h, and morphine was administered by intravenous injection when necessary; patients in group B (n=31 received a 0.5-2.0mg/kg loading dose of propofol within 10min, maintained with 1.0-3.0mg/(kg.h for 72h, and morphine was administered by intravenous injection when necessary; patients in group C (n=27 received an intramuscular injection of pethidine or other optional drugs as control. A comprehensive evaluation was performed using Riker sedation-agitation scale combined with physiological and physical response indicators. The blood pressure, heart rate, respiration, tidal volume, arterial blood gas, plasma cortisol, plasma β-endorphin (β-EP, peripheral WBC count and blood glucose were measured and compared in 3 groups. Results　The sedation rate of single-drug (i.e., without morphine administration in groups A, B and C was 86.7%, 80.6% and 77.8% respectively, and no significant difference was found among 3 groups (P>0.05. The mean arterial blood pressure at 30 min after administration was lower than that before administration in group A (P0.05. The WBC count and plasma cortisol level at 24h after treatment were lower than those before administration of the drugs in group A (P0.05. Conclusions　Dexmedetomidine could alleviate the stress as a result of moderate and severe TBI, and its anti-stress and sedative effects were similar to those of propofol, but it is necessary to monitor the blood pressure. β-EP may play a coordinating role in the early stage of effect

We oppose the opinion that the intra-arterial administration of iodine-based contrast media (CM) appears to pose a greater risk of contrast medium-induced nephropathy (CIN) than intravenous administration since (1) in intra-arterial coronary procedures and most other intra-arterial angiographic examinations, CM injections are also intravenous relative to the kidneys, (2) there is a lack of comparative trials studying the risk of CIN between intra-arterial and intravenous procedures with matched risk factors and CM doses, (3) a bias selection of patients with fewer risk factors may explain the seemingly lower rate of CIN after CT in comparison with coronary interventions, (4) the rate of CIN following intra-arterial coronary procedures may also be exaggerated owing to other causes of acute kidney failure, such as haemodynamic instability and microembolisation, (5) roughly the same gram-iodine/GFR ratio ({approx}1:1) as a limit of relatively safe CM doses has preliminarily been found for both intravenous CT and intra-arterial coronary procedures and (6) the substantially higher injected intravenous CM dose rate during CT relative to an intra-arterial coronary procedure might actually pose a higher risk of CIN following CT. Key Points circle Most intra-arterial injections of contrast media are intravenous relative to the kidneys. circle No evidence that intravenous CM injections should be less nephrotoxic than intra-arterial. circle Considerably higher dose rates of CM are used for CT relative to intra-arterial procedures. circle Higher dose rates may pose higher nephrotoxic risk for intravenous based CT studies.

[corrected] We aimed to evaluate analgesic efficacy, opioid-sparing, and opioid-related adverse effects of intravenous paracetamol and intravenous dexketoprofen trometamol in combination with iv morphine after total abdominal hysterectomy. Sixty American Society of Anesthesiologist Physical Status Classification I-II patients scheduled for total abdominal hysterectomy were enrolled to this double-blinded, randomized, placebo controlled, and prospective study. Patients were divided into three groups as paracetamol, dexketoprofen trometamol, and placebo (0.9% NaCl) due to their post-operative analgesic usage. Intravenous patient controlled analgesia morphine was used as a rescue analgesic in all groups. Pain scores, hemodynamic parameters, morphine consumption, patient satisfaction, and side-effects were evaluated. Visual Analog Scale (VAS) scores were not statistically significantly different among the groups in all evaluation times, but decrease in VAS scores was statistically significant after the evaluation at 12(th) h in all groups. Total morphine consumption (morphine concentration = 0.2 mg/ml) in group paracetamol (72.3 ± 38.0 ml) and dexketoprofen trometamol (69.3 ± 24.1 ml) was significantly lower than group placebo (129.3 ± 22.6 ml) (P dexketoprofen trometamol after surgery and the increase in global satisfaction score was significant only in group placebo. Dexketoprofen trometamol and Paracetamol didn't cause significant change on pain scores, but increased patients' comfort. Although total morphine consumption was significantly decreased by both drugs, the incidence of nausea and vomiting were similar among the groups. According to results of the present study routine addition of dexketoprofen trometamol and paracetamol to patient controlled analgesia morphine after hysterectomies is not recommended.

The AVOID-HF (Aquapheresis versus Intravenous Diuretics and Hospitalization for Heart Failure) trial tested the hypothesis that patients hospitalized for HF treated with adjustable ultrafiltration (AUF) would have a longer time to first HF event within 90 days after hospital discharge than those receiving adjustable intravenous loop diuretics (ALD). Congestion in hospitalized heart failure (HF) patients portends unfavorable outcomes. The AVOID-HF trial, designed as a multicenter, 1-to-1 randomized study of 810 hospitalized HF patients, was terminated unilaterally and prematurely by the sponsor (Baxter Healthcare, Deerfield, Illinois) after enrollment of 224 patients (27.5%). Aquadex FlexFlow System (Baxter Healthcare) was used for AUF. A Clinical Events Committee, blinded to the randomized treatment, adjudicated whether 90-day events were due to HF. A total of 110 patients were randomized to AUF and 114 to ALD. Baseline characteristics were similar. Estimated days to first HF event for the AUF and ALD group were, respectively, 62 and 34 (p = 0.106). At 30 days, compared with the ALD group, the AUF group had fewer HF and cardiovascular events. Renal function changes were similar. More AUF patients experienced an adverse effect of special interest (p = 0.018) and a serious study product-related adverse event (p = 0.026). The 90-day mortality was similar. Compared with the ALD group, the AUF group trended toward a longer time to first HF event within 90 days and fewer HF and cardiovascular events. More patients in the AUF group experienced special interest or serious product-related adverse event. Due to the trial's untimely termination, additional AUF investigation is warranted.

Full Text Available Intractable epilepsy in children poses a serious medical challenge. Acute repetitive seizures and status epilepticus leads to frequent emergency room visits and hospital admissions. Permanent neurological damage can occur if there is delay in treatment. It has been shown that these children continue to remain intractable even after acute seizure management with approved FDA agents. Intravenous levetiracetam, a second-generation anticonvulsant was approved by the FDA in 2006 in patients 16 years and older as an alternative when oral treatment is not an option. It has been shown that oral levetiracetam can be used in the treatment of status epilepticus and acute repetitive seizures. Data have been published showing that intravenous levetiracetam is safe and efficacious, and can be used in an acute inpatient setting. This current review will discuss the recent data about the safety and tolerability of intravenous levetiracetam in children and neonates, and emphasize the need for a larger prospective multicenter trial to prove the efficacy of this agent in acute seizure management.

All were males with a mean age of 36.9 years. Hemorrhage was the most common reason (93.8 %) for seeking medical care, and 3 of these patients were in hemorrhagic shock at admission. All patients received broad-spectrum antibiotics, and debridement and drainage were implemented after SG placement. 7 of the 13 cases which had microbiologic results showed mixed infections, while gram-negative bacteria were the major pathogens. Except for 2 patients, who were lost to follow-up, two new pseudoaneurysms formed due to delayed debridement, and one stent thrombosis occurred, none of the remaining cases had SG infection or developed claudication.ConclusionsSG placement controls massive hemorrhage rapidly, gives enough time for subsequent treatment for pseudoaneurysms due to intravenous drug abuse, and reduces the incidence of postoperative claudication. With appropriate broad-spectrum antibiotics and early debridement, the incidence of SG infection is relatively low. It is an effective alternative especially as temporary bridge measure for critical patients. However, the high cost, uncertain long-term prospects, high demand for medical adherence, and the risk of using the conduits for re-puncture call for a cautious selection of patients.

2002-01-01

The aim of this study was to determine whether intravenous (IV) glucagon and dual positioning administered prior to CT colonography enhances colonic distention. We assessed the effect of dual positioning and IV glucagon on colonic distention in 96 patients who underwent CT colonography examinations. The CT colonography was performed in both supine and prone positions. Seventy-four patients received glucagon (1 mg i.v.) immediately prior to CT scanning and 22 patients did not. The bowel was divided into ten segments and colonic distention was scored by two radiologists in the supine, prone, and combined supine/prone positions using a five-point scale: 1=collapsed; 2=poorly visualized; ≥3=adequate distention; 4=entire segment visualized and well distended; 5=excellent distention. A combined segmental and overall supine/prone distention score was calculated based on the sum of the mean score for each position. There was no significant difference in the degree of colonic distention between patients who received glucagon and those who did not [supine/prone distention score (mean±SE): 3.63±0.2 vs 3.85±0.2; p=n.s.]. The degree of colonic distention was greater in the prone position in both the glucagon (3.87±0.2 vs 3.38±0.2; p<0.05) and non-glucagon groups (4.01±0.2 vs 3.69±0.2; p=N.S.) particularly in the proximal colon. There was almost perfect agreement between both radiologists in their scoring of colonic distention on a per-patient basis (k=0.9; p<0.001). Of 1480 bowel segments, 1261 (85.2%) were adequately distended in the glucagon group compared with 370 of 440 bowel segments (84%) in the non-glucagon group (p=n.s.) Colonic distention at CT colonography is improved by dual positioning but not by the administration of intravenous glucagon. While our results suggest that other smooth muscle relaxants, including butyl scopolamine, may only have a limited role in improving colonic distention in CT colonography, further studies are required.

2017-06-01

This randomized trial investigated whether a 2-dose administration of intravenous ramosetron (5-hydroxytryptamine type 3 receptor antagonist) is more effective than a single-dose administration in preventing postoperative nausea and vomiting (PONV) in 89 patients who were scheduled to undergo laparoscopic operation for benign gynecologic diseases and to receive intravenous patient-controlled analgesia for relief of postoperative pain. After assignment at a ratio of 1:1, intravenous ramosetron (0.3 mg) was initially administered at the end of skin closure in all patients. Thereafter, ramosetron (0.3 mg) and placebo were administered to the study and control groups, respectively, at 4 hours after the operation. The baseline and operative characteristics were similar between the groups. The incidence of PONV during the 24-hour period after operation which was assessed as the primary endpoint did not differ between the groups. No serious adverse events occurred in either group. A 2-dose administration of intravenous ramosetron may not be superior to a single-dose administration in preventing PONV in patients undergoing laparoscopic operation for benign gynecologic diseases.

To report what we believe to be the first 2 cases of long-term (>24 months) intermittent intravenous interleukin-2 receptor antibody (IL-2RA) therapy for maintenance immunosuppression following renal transplantation. The first patient is a 52-year-old female with a history of intolerance to calcineurin inhibitors (CNIs) and sirolimus. Following her second transplant, the patient received mycophenolate mofetil 100 mg twice daily, a tapering corticosteroid regimen (initial dose of methylprednisolone 500 mg tapered over 1 week to prednisone 30 mg/day), and biweekly intravenous daclizumab 1-1.2 mg/kg/dose; 33 months after transplant the IL-2RA was changed to intravenous basiliximab 40 mg once a month. At 40 months after transplant, the patient continued to have stable renal function (estimated glomerular filtration rate 48 mL/min/1.73 m²) with excellent tolerability. The second patient is a 59-year-old female also intolerant to CNIs and sirolimus who required intermittent maintenance therapy with intravenous basiliximab 20 mg/dose. Despite an initial rejection episode, the patient tolerated more than 2 years of basiliximab therapy with good renal function (estimated glomerular filtration rate 103 months after transplant 69 mL/min/1.73 m²) and no adverse events. The IL-2RAs basiliximab and daclizumab possess several characteristics of ideal maintenance immunosuppressive agents (ie, nondepleting, long half-lives, limited adverse events). Based on a MEDLINE search (through December 31, 2010) using the search terms basiliximab, daclizumab, organ transplant, immunosuppression, and/or maintenance immunosuppression, and an advanced search in the published abstracts from the American Transplant Congress and World Transplant Congress (2000-2010), it appears that IL-2RAs have been used successfully as short-term therapy in both renal and extrarenal transplant recipients to allow for renal recovery following CNI-induced nephrotoxicity. In heart transplant recipients, the IL-2

Intravenous thrombolysis with alteplase alone cannot reperfuse most large-artery strokes. We aimed to determine whether mechanical thrombectomy in addition to intravenous thrombolysis improves clinical outcome in patients with acute ischaemic stroke. THRACE is a randomised controlled trial done in 26 centres in France. Patients aged 18-80 years with acute ischaemic stroke and proximal cerebral artery occlusion were randomly assigned to receive either intravenous thrombolysis alone (IVT group) or intravenous thrombolysis plus mechanical thrombectomy (IVTMT group). Intravenous thrombolysis (alteplase 0·9 mg/kg [maximum 90 mg], with an initial bolus of 10% of the total dose followed by infusion of the remaining dose over 60 min) had to be started within 4 h and thrombectomy within 5 h of symptom onset. Occlusions had to be confirmed by CT or magnetic resonance angiography. Randomisation was done centrally with a computer-generated sequential minimisation method and was stratified by centre. The primary outcome was the proportion of patients achieving functional independence at 3 months, defined by a score of 0-2 on the modified Rankin scale, assessed in the modified intention-to-treat population (ie, patients lost to follow-up and those with missing data were excluded). Safety outcomes were analysed in the per-protocol population (ie, all patients who did not follow the protocol of their randomisation group precisely were excluded from the analysis). THRACE is registered with ClinicalTrials.gov, NCT01062698. Between June 1, 2010, and Feb 22, 2015, 414 patients were randomly assigned to the IVT group (n=208) or the IVTMT group (n=204). Four patients (two in each group) lost to follow-up and six (four in the IVT group and two in the IVTMT group) with missing data were excluded. 85 (42%) of 202 patients in the IVT group and 106 (53%) of 200 patients in the IVTMT group achieved functional independence at 3 months (odds ratio 1·55, 95% CI 1·05-2·30; p=0·028).

One hundred twenty-seven newborn infants requiring parenteral nutrition were randomly assigned to receive differing amounts of zinc (40 to 400 micrograms/kg/day) and copper (20 or 40 micrograms/kg/day) supplementation within five birth weight groups (600 to 2,500 gm). The serum zinc concentration remained relatively constant in the group receiving the most zinc supplementation after two weeks of therapy, but declined sharply in the groups receiving less supplementation. No effect of increased copper intake was noted on ceruloplasmin values, but a difference in serum copper concentrations was noted at two weeks. No correlation was noted between serum zinc and copper values or among those for serum zinc, retinol-binding protein, and prealbumin. Reference ranges were defined for serum zinc, copper, retinol-binding protein, prealbumin, and ceruloplasmin in the preterm infant.

Full Text Available This study investigated efficacy and side effects of Morphine suppository for pain management after the first elective caesarean delivery in comparison to Diclofenac suppository. One hundred women aged 18-40 with term pregnancies undergoing elective caesarean section for the first time participated in this prospective project. Exclusion criteria included drug sensitivity, fetal malformations or defects, and complications during the cesarean operation. After same spinal anesthesia and same surgical techniques and in the recovery room patients consecutively received 100 mg diclofenac suppository or 10 mg morphine suppository. The pain severity was rated by “Numerical Rating Scale.” There was not the difference between two groups in terms of basal information. Pain score was significantly different between two groups in the first 12 hours (5.66 ±1.36 in morphine group and 3.63±0.96 in diclofenac group but not in the second 12 hour period. Considering pain scores every two hours in first 12 hours and every 4 hours in second 12 hours, morphine group had higher scores in comparison to diclofenac group. Also, the morphine group required pethidine injection sooner than the other group. The time giving first pethidine injection was 3.28±2.16 hours after operation in morphine group and 5.24±4.07 hours after operation (P<0.05. This study demonstrated that diclofenac suppository in comparison to morphine suppository decreased subjective pain scores in the first twenty-four hours after elective caesarean section which reached statistical significance in the first twelve hours. Although in diclofenac group, pethidine injection was prescribed significantly later.

Contrast-induced nephropathy (CIN) is a recognised complication of intravascular administration of iodinated contrast media (ICM). Previous studies suggest a higher incidence in the elderly, but no large study has assessed this to date. We set out to assess changes in creatinine in elderly inpatients following computed tomography (CT) examination and compare those who received intravenous contrast to those who did not. Methods. Using the Radiology Information System in two teaching hospitals, inpatients over the age of seventy who had a CT examination and a baseline creatinine were identified and their follow-up creatinine levels were analysed. Elderly inpatients who underwent a non contrast CT over the same period were used as controls. Results. 677 elderly inpatients who received ICM were compared with 487 controls. 9.2% of patients who received ICM developed acute kidney injury (AKI) compared to 3.5% of inpatient controls (Ρ<0.0001). Patients with higher baseline eGFR had a higher incidence of post-CT AKI. Conclusions. The incidence of post-CT AKI is higher in patients who received IV ICM compared to those who did not; the difference may be partly attributable to contrast-induced nephropathy. This suggests that the incidence of CIN in the elderly may not be as high as previously thought.

A survey of 67 nuclear medicine departments revealed no agreement on which radiolabeled agents could be injected through intravenous lines (IVs) and which required direct venipuncture. Labeled cells and several common radiopharmaceuticals were tested for adherence to intravenous tubing. Residual activity remaining in the tubing after an adequate flush was less than 1% of the injected dose in each case. Administration of radiolabeled agents through existing IVs is an acceptable alternative to direct venipuncture in many cases

Bullous pemphigoid is an autoantibody-mediated skin blistering disease. Previous studies revealed that intravenous Ig is therapeutic in animal models of bullous pemphigoid by saturating the IgG-protective receptor FcRn, thereby accelerating degradation of pathogenic IgG. Sasaoka et al. demonstrate that the inhibitory effects of intravenous Ig on bullous pemphigoid are also associated with negative modulation of cytokine production by keratinocytes.

Methamphetamine is one of the widely abused drugs. In spite of a number of studies, there is still little successful therapy to suppress the methamphetamine abuse. Acupuncture has shown to attenuate the reinforcing effects of psychostimulant. Based on, the present study investigated if acupuncture could suppress intravenous methamphetamine self-administration behavior. In addition, a possible neuronal mechanism was investigated. Male Sprague-Dawley rats weighing 270-300g were trained to intake food pellet. After catheter implantation, animal was trained to self-administer methamphetamine (0.05mg/kg) intravenously using fixed ratio 1 schedule in daily 2h session during 3 weeks. After training, rats who established baseline (infusion variation less than 20% of the mean for 3 consecutive days) received acupuncture treatment on the next day. Acupuncture was performed at each acupoint manually. In the second experiment, the selective antagonists of GABA A or GABA B receptor were given before acupuncture to investigate the possible neuronal involvement of GABA receptor pathway in the acupuncture effects. C-Fos expression was examined in the nucleus accumbens to support behavioral data. Acupuncture at HT7, but not at control acupoint LI5, reduced the self-administration behavior significantly. Also, the effects of acupuncture were blocked by the GABA receptor antagonists. C-Fos expression was shown to be parallel with the behavioral data. Results of this study have shown that acupuncture at HT7 suppressed methamphetamine self-administration through GABA receptor system, suggesting that acupuncture at HT7 can be a useful therapy for the treatment of methamphetamine abuse.

THE ROLE OF IgM-ENRICHED INTRAVENOUS IMMUNOGLOBULIN IN TRANSPLANTATION

Directory of Open Access Journals (Sweden)

Szabó Judit

2014-04-01

Full Text Available After organ transplantation, gamma globulin and intravenous immunoglobulin enriched with IgM are most frequently used in septic shock as early immune-support. If the explanted organ is infected, the transplantation, as a life-saving operation, can be performed if there is no systemic inflammation and the patient receives IgM enriched immunoglobulin prophylaxis during surgery. The period after transplantation can be divided into three parts from the infection point of view: the first month after transplantation, the first sixth months and the following six months. Infections within the first month are basically related to the surgical procedure. Because of the immunosuppressive therapy, the opportunistic and fungal infections are more common during the first sixth months. After this period, the occurrence and the type of infections are similar to that of the non-transplant population except for pulmonary infections. The latter is two to three times more frequent. This is explained by the secondary hypogammaglobulinaemia (lower blood levels of IgM and IgG which is caused by the steroids but most of mycophenolate mofetil by inhibition of the T and B lymphocyte proliferation. Septic shock develops with a continuing fall of IgM levels. Under these circumstances additional intravenous immunoglobulin therapy with IgM can be lifesaving. Besides, immunoglobulin concentrates with IgM may also be used in the case of viral infections without prophylaxis and/or without etiological therapy such as in the case of West Nile virus infection. As a result of the increase in antibiotic resistance, the application of immunotherapy, including immunoglobulins may become the mainstream in the treatment of septic shock.

This study aimed to determine the effect of intravenous acetaminophen versus placebo on postoperative pain, satisfaction with pain control, and narcotic use after vaginal reconstructive surgery. This was an institutional review board-approved, double-blind placebo-controlled randomized trial. Women scheduled for reconstructive surgery including vaginal hysterectomy and vaginal vault suspension were enrolled. Subjects received 1000 mg of intravenous acetaminophen or 100 mL placebo every 6 hours for 24 hours. Pain and satisfaction with pain control were assessed using visual analog scales and a numeric rating scale. Visual analog scales were collected at 18 and 24 hours postoperatively and at discharge. A sample size calculation determined 90 subjects would be required to detect a 30% reduction in postoperative narcotic use with 80% power and significance level of 0.05. One hundred subjects were enrolled. There were no differences in demographics or surgical data and no difference in narcotic consumption at multiple evaluation points. At 18 hours postoperative, median pain scores at rest were 27.0 (interquartile range, 35.0) for acetaminophen and 35.0 (interquartile range, 44.5) for placebo, finding no difference (P = 0.465). Furthermore, pain with activity and numeric rating scale-assessed pain scales were similar (P = 0.328; P = 0.597). Although satisfaction with pain control was high overall (91.5), no difference was noted. Patients undergoing vaginal reconstructive surgery receiving perioperative intravenous acetaminophen did not experience a decrease in narcotic requirements or postoperative pain when compared with placebo. Reassuringly, pain scores were low and satisfaction with pain control was high for all subjects. The general use of this medication is not supported in these surgical patients.

Full Text Available ABSTRACT Objective: To compare topical vs. intravenous tranexamic acid (TA in total knee arthroplasty regarding blood loss and transfusion., Methods: Ninety patients were randomized to receive TA intravenously (20 mg/kg in 100 mL of saline; group IV, topically (1.5 g in 50 mL of saline, sprayed over the operated site, before release of the tourniquet; topical group, or intravenous saline (100 mL with anesthesia; control group. The volume of drained blood in 48, h, the amount of transfused blood, and the serum levels of hemoglobin and hematocrit before and after surgery were evaluated., Results: The groups were similar for gender, age, weight, laterality, and preoperative hemoglobin and hematocrit levels (p> 0.2. The hemoglobin level dropped in all groups when comparing the preoperative and the 48-h evaluations: the control group decreased 3.8 mg/dL on average, while the IV, group had a decrease of 3.0, and the topical group, of 3.2 (p= 0.019. The difference between the control and IV, groups was confirmed by Bonferroni test (p= 0.020. The difference between the control group and the topical group was not significant (p= 0.130, although there was less reduction in hemoglobin in the topical group; the comparison between the IV, group and the topical group was also not significant (p= 1.000. Conclusion: Using topic and IV, tranexamic acid decreased blood loss and the need for transfusion in total knee arthroplasty. Topical application showed results similar to IV use regarding the need for blood transfusion, but without the possible side effects of IV, administration.

We assessed the relationship between antibodies to infliximab (ATI) and the loss of response postinfliximab, infusion reactions and, in a randomized trial, investigated whether intravenous hydrocortisone premedication can reduce ATI. Initially, we prospectively evaluated clinical response, adverse events, and ATI levels in 53 consecutive patients with Crohn's disease who received 199 infliximab (5 mg/kg) infusions. Subsequently, 80 patients with Crohn's disease were randomized to intravenous hydrocortisone 200 mg or placebo immediately before their first and subsequent infliximab infusions. The primary endpoint was reduction in median ATI levels at week 16. Analysis was by intention to treat. Nineteen of our initial 53 patients (36%) developed ATI, including all 7 patients with serious infusion reactions (median ATI level, 19.6 microg/mL). Eleven of 15 patients (73%) who lost their initial response were ATI positive compared with none of 21 continuous responders, (8.9 vs. 0.7 microg/mL, P < 0.0001). Administering a second infusion within 8 weeks of the first (OR, 0.13; 95% CI, 0.03-0.5; P = 0.0007) or concurrent immunosuppressants (OR, 0.19; 95% CI, 0.04-1.03; P = 0.007) significantly reduced ATI formation. In the placebo-controlled trial, ATI levels were lower at week 16 among hydrocortisone-treated patients (1.6 vs. 3.4 microg/mL, P = 0.02), and 26% of hydrocortisone-treated patients developed ATI compared with 42% of placebo-treated patients, P = 0.06. Loss of initial response and infusion reactions post-infliximab is strongly related to ATI formation and level. Administering a second infusion within 8 weeks of the first and concurrent immunosuppressant therapy significantly reduce ATI formation. Intravenous hydrocortisone premedication significantly reduces ATI levels but does not eliminate ATI formation or infusion reactions.

Why intravenous moderate sedation should be taught in graduate endodontic programs.

Science.gov (United States)

Montagnese, Thomas Anthony

2012-03-01

The purpose of this opinion article is to present reasons why intravenous moderate sedation should be taught in graduate endodontic programs. Access to oral health care is an area of much interest and concern, but some patients are unable to get endodontic care because they have special needs. Special needs can refer to patients who fear dentistry itself and other aspects of dental treatment. A variety of phobias and medical, developmental, and physical conditions can make it difficult for some patients to tolerate the endodontic care they need and want. Moderate sedation can help many of these patients. Endodontists in general are not trained to provide intravenous moderate sedation. By incorporating intravenous moderate sedation into endodontic practice, many of these patients can be treated. The first step in achieving this goal is to add intravenous moderate sedation training to graduate endodontic programs. The long-term effect will be to make specialty endodontic care available to more people.

Variation in Clinical Practice of Intravenous Thrombolysis in Stroke in the Netherlands

Directory of Open Access Journals (Sweden)

Auke Bauer

2013-04-01

Full Text Available In the Netherlands in 2010, 11% of patients with ischemic stroke received intravenous thrombolysis (IVT, varying from 4 to 26% between hospitals. The aim of this study was to investigate variation in clinical practice and organization of IVT in relationship to performance and outcome. In all 84 Dutch hospitals performing IVT, a stroke neurologist was approached using a web-based survey. The response rate was 82%. The study showed considerable variation. For example, door-to-needle time ranged from 25 to 80 min. High blood pressure was actively lowered before performing IVT by 57% of neurologists, while 35% chose to wait. 28% started IVT without knowledge of laboratory results. Better follow-up data are needed to see whether this variation results in differences in outcome.

Full Text Available The ultrastructural research has a decisive role in gathering the knowledge on the liver’s response to the influence of some drugs. The aim of the study was to perform an ultrastructurai analysis of the liver in chronic intravenous heroin addicts.The study involved the autopsy conducted on 40 bodies of intravenous heroin addicts and 10 control autopsies. The liver tissue was fixed in glutaraldehyde and moulded with epon for investigation purposes of ultrastructural changes. The analysis was performed using the method of transmission electron microscopy.In the group of intravenous heroin addicts, the liver autopsy samples showed degenerative vesicular and fat changes, chronic active and persistent hepatitis, cirrhosis, reduction in the amount of glycogen in hepatocytes, as well as the Kupffer cell’s dominant hypertrophy. Various changes occur in organelles, plasma membrane of hepatocytes and biliary channels as well as in the nucleus.The most important ultrastructural findings include: hyperplasia and hypertrophy of the smooth endoplasmic reticulum, which is histologically proven vesicular degeneration of hepatocyte occurring as a result of the increased synthesis of enzymes of smooth endoplasmic reticulum due to chronic intravenous heroin intake, and the presence of continuous basal membrane followed by transformation of the sinusoids into capillaries (in the cases of chronic active hepatitis and cirrhosis which leads to a disorder of microcirculation and further progress of cirrhosis.

• BACKGROUND: Magnesium (Mg has been used as an adjuvant medication in postoperative analgesia. We planed this study to assess the effects of Mg, when added to lidocaine in intravenous regional anesthesia (IVRA on the tourniquet pain.
• METHODS: Forty patients undertaking hand surgery were randomly allocated into 2 groups to be given IVRA. They received 20 ml lidocaine 1% diluted with 20 ml saline to a total of 40 ml in the group L (n = 20 or 7.5 ml magnesium sulfate 20% plus 20 ml lidocaine 1% diluted with 12.5 ml saline to a total of 40 ml in the group M (n = 20. Sensory and motor block onset and recovery times, anesthesia and operation qualities were recorded. Before and after the tourniquet use at 5, 10, 15, 20, 30, 40, and 50 minutes, hemodynamic variables, tourniquet pain, and analgesic use were noted. Subsequent to the tourniquet deflation, at 6, 12, and 24 hours, hemodynamic variables, pain, time to first analgesic requirement, analgesic use and side effects were recorded.
• RESULTS: Shortened sensory and motor block onset times were established in group M (P < 0.05. Visual analog scale (VAS scores were less in group M at 20, 30, 40, and 50 minutes after tourniquet inflation (P < 0.05. Intraoperative, analgesic requirement was less in group M (P < 0.05. Anesthesia excellence, as determined by the anesthesiologist and surgeon, was significantly better in group M (P < 0.05. Time to the first analgesic requirement in group M was 53.75 ± 6.94 minutes and in group L was 40.76 ± 14.55 minutes (P < 0.05. Postoperative VAS scores were higher at 6, 12, and 24 hours in group L (P < 0.05.

Intravenous Iron Administration and Hypophosphatemia in Clinical Practice

Directory of Open Access Journals (Sweden)

S. Hardy

2015-01-01

Full Text Available Introduction. Parenteral iron formulations are frequently used to correct iron deficiency anemia (IDA and iron deficiency (ID. Intravenous formulation efficacy on ferritin and hemoglobin level improvement is greater than that of oral formulations while they are associated with lower gastrointestinal side effects. Ferric carboxymaltose- (FCM- related hypophosphatemia is frequent and appears without clinical significance. The aim of this study was to assess the prevalence, duration, and potential consequences of hypophosphatemia after iron injection. Patients and Methods. The medical records of all patients who underwent parenteral iron injection between 2012 and 2014 were retrospectively reviewed. Pre- and postinjection hemoglobin, ferritin, plasma phosphate, creatinine, and vitamin D levels were assessed. Patients who developed moderate (range: 0.32–0.80 mmol/L or severe (<0.32 mmol/L hypophosphatemia were questioned for symptoms. Results. During the study period, 234 patients received iron preparations but 104 were excluded because of missing data. Among the 130 patients included, 52 received iron sucrose (FS and 78 FCM formulations. Among FS-treated patients, 22% developed hypophosphatemia versus 51% of FCM-treated patients, including 13% who developed profound hypophosphatemia. Hypophosphatemia severity correlated with the dose of FCM (p=0.04 but not with the initial ferritin, hemoglobin, or vitamin D level. Mean hypophosphatemia duration was 6 months. No immediate clinical consequence was found except for persistent fatigue despite anemia correction in some patients. Conclusions. Hypophosphatemia is frequent after parenteral FCM injection and may have clinical consequences, including persistent fatigue. Further studies of chronic hypophosphatemia long-term consequences, especially bone assessments, are needed.

Enhanced recovery protocols frequently use multimodal postoperative analgesia to improve postoperative outcomes in patients undergoing colorectal surgery. The purpose of this study was to evaluate liposomal bupivacaine use in transversus abdominis plane blocks on postoperative pain scores and opioid use after colorectal surgery. This was a retrospective cohort study comparing outcomes between patients receiving nonliposomal anesthetic (n = 104) and liposomal bupivacaine (n = 303) blocks. The study was conducted at a single tertiary care center. Patients included those identified within an institutional database as inpatients undergoing colorectal procedures between 2013 and 2015 who underwent transversus abdominis plane block for perioperative analgesia. The study measured postoperative pain scores and opioid requirements. Patients receiving liposomal bupivacaine had significantly lower pain scores for the first 24 to 36 postoperative hours. Pain scores were similar after 36 hours. The use of intravenous opioids among the liposomal bupivacaine group decreased by more than one third during the hospitalization (99.1 vs 64.5 mg; p = 0.040). The use of ketorolac was also decreased (49.0 vs 18.3 mg; p bupivacaine group but did not achieve statistical significance. The study was limited by its retrospective, single-center design and heterogeneity of block administration. Attenuated pain scores observed with liposomal bupivacaine use were associated with significantly lower intravenous opioid and ketorolac use, suggesting that liposomal bupivacaine-containing transversus abdominis plane blocks are well aligned with the opioid-reducing goals of many enhanced recovery protocols.

2017-06-01

Poison hemlock (Conium maculatum) is a common plant with a significant toxicity. Data on this toxicity is sparse as there have been few case reports and never a documented poisoning after intravenous injection. We present a case of intravenous poison hemlock injection encountered in the emergency department. We describe a 30-year-old male who presented to the emergency department after a brief cardiac arrest after injecting poison hemlock. The patient had return of spontaneous circulation in the emergency department but had prolonged muscular weakness and encephalopathy later requiring tracheostomy. Intravenous injection of poison hemlock alkaloids can result in significant toxicity, including cardiopulmonary arrest, prolonged weakness, and encephalopathy.

Controversy over the optimal intravenous fluid for volume resuscitation continues unabated. Our objectives were to characterize the demographics of physicians who prescribe intravenous colloids and determine factors that enter into their decision to choose a colloid. Questionnaire with 61 items. Ten percent ( n = 364) of frequent intravenous fluid prescribers in the province of Ontario, Canada. The response rate was 74%. Colloid use in the past year was reported by 79% of the responding physicians. Important reasons for choosing a colloid included blood loss and manipulation of oncotic pressure. Physicians tended to prefer either albumin or pentastarch, but no important reasons were found for choosing between the two. Albumin with or without crystalloid was preferred in 5/13 scenarios by more than 50% of the respondents, whereas pentastarch was not favored by more than 50% of respondents in any scenario. Physicians practising in critical care areas and teaching hospitals generally preferred pentastarch to albumin. Physicians reporting pentastarch as representing greater than 90% of total colloid use were more likely to have been visited by a drug detailer for pentastarch than those who used less synthetic colloid (54 vs 22%, p distribution. Although albumin appeared to be preferred in more clinical niches, most physicians did not state reasons for choosing between products. Marketing, specialty, location of practice and clinical scenario appear to play significant roles in the utilization of colloid products.

Full Text Available Background: Parkinson's disease is a deficiency of dopamine in the striatum, characterized by bradykinesis, rigidity and resting tremor. Adipose tissue-Derived Stem Cells (ADSCs have many advantages for cell therapy because of the easy availability and pluripotency without ethical problems. In this research, the effects of ADSCs transplantation on motor impairment of rat Parkinsonian models were evaluated. Materials and Methods: Parkinson model was constructed by the unilateral lesion of striatum of male Wistar rats using 20µg of 6-hydroxydopamine (6-OHDA as lesion group. Cell and α-MEM (α-minimal essential medium groups were lesioned animals that received intravenous injection of 3×106 cells suspended in medium and medium repectively. All rats were evaluated behaviorally with rotarod and apomorphine-induced rotation tests, at 4 and 8 weeks after cell transplantation. Results: Lesion and α-MEM groups showed increased contralateral turns while cell group significantly ameliorated both in rotarod and apomorphine-induced rotation tests. There was a significant difference of contralateral turns between cell and lesioned groups at 8 weeks after transplantation. Lesioned rats showed significant decrease of staying on the rod as compared to control, but in cell group there was a significant increase in comparision with the lesioned animals. Conclusion: ADSCs injected intravenously promote functional recovery in Parkinsonian rats.

Full Text Available Background: Spinal anaesthesia is the preferred technique to fix fracture of the femur. Extreme pain does not allow ideal positioning for this procedure. Intravenous fentanyl and femoral nerve block are commonly used techniques to reduce the pain during position for spinal anaesthesia however; results are conflicting regarding superiority of femoral nerve block over intravenous fentanyl. Aims: We conducted this study to compare the analgesic effect provided by femoral nerve block (FNB and intra- venous (IV fentanyl prior to positioning for central neuraxial block in patients undergoing surgery for femur fracture. Patients and Methods: In this randomized prospective study 60 patients scheduled for fracture femur operation under spinal were included. Patients were distributed in two groups through computer generated random numbers table; Femoral nerve block group (FNB and Intravenous fentanyl group (FENT. In FNB group patients received FNB guided by a peripheral nerve stimulator (Stimuplex; B Braun, Melsungen, AG 5 minutes prior to positioning. 20mL, 1.5% lidocaine with adrenaline (1:200,000 was injected incrementally after a negative aspiration test. Patients in the fentanyl group received injection fentanyl 1 μg/kg IV 5 mins prior to positioning. Spinal block was performed and pain scores before and during positioning were recorded. Statistical analysis was done with Sigmaplot version-10 computer software. Student t-test was applied to compare the means and P < 0.05 was taken as significant.

The study compared the effectiveness of ketamine and midazolam/fentanyl as procedural sedation and analgesia agents for reduction of fractures and dislocated joints. Forty-one adult patients were enrolled by convenience sampling. They were randomized to receive ketamine or midazolam/fentanyl. Depth of sedation, pain score, procedural outcome and memory of the procedure were documented. The ketamine group had deeper sedation, but there was no statistical difference in other variables between the two groups. Three patients in the midazolam/fentanyl group had oxygen desaturation. More adverse effects were associated with ketamine. Intravenous ketamine is as effective as midazolam/fentanyl for procedural sedation.

The purpose of this study was to investigate the incidence of fosaprepitant-associated infusion site adverse events (ISAEs) among a cohort of breast cancer patients receiving doxorubicin/cyclophosphamide (AC) chemotherapy. A retrospective review of electronic medical record (EMR) data was performed for all patients who were initiated on AC from January 2011 to April 2012. Data collected included baseline demographics, antiemetic regimen, documentation of ISAEs, and type of intravenous (IV) access. Descriptive statistics (mean and standard deviation or percentages) were summarized overall, by type of IV access and initial antiemetic given. Among the 148 patients included in this analysis, 98 initially received fosaprepitant and 44 received aprepitant. The incidence of ISAEs associated with fosaprepitant administration was 34.7 % (n=34), while the incidence of aprepitant-associated ISAEs was 2.3 % (n=1). All ISAEs were associated with peripheral IV access. The most commonly reported ISAEs were infusion site pain (n=26), erythema (n=22), swelling (n=12), superficial thrombosis (n=8), infusion site hives (n=5), and phlebitis/thrombophlebitis (n=5). Twenty-six patients experienced more than one type of ISAE. The incidence and severity of ISAEs associated with fosaprepitant administration among a group of patients receiving AC chemotherapy are significant and appreciably higher than what has been previously reported.

Full Text Available Backround: We aimed to evaluate analgesic efficacy, opioid-sparing, and opioid-related adverse effects of intravenous paracetamol and intravenous dexketoprofen trometamol in combination with iv morphine after total abdominal hysterectomy. Materials and Methods: Sixty American Society of Anesthesiologist Physical Status Classification I-II patients scheduled for total abdominal hysterectomy were enrolled to this double-blinded, randomized, placebo controlled, and prospective study. Patients were divided into three groups as paracetamol, dexketoprofen trometamol, and placebo (0.9% NaCl due to their post-operative analgesic usage. Intravenous patient controlled analgesia morphine was used as a rescue analgesic in all groups. Pain scores, hemodynamic parameters, morphine consumption, patient satisfaction, and side-effects were evaluated. Results: Visual Analog Scale (VAS scores were not statistically significantly different among the groups in all evaluation times, but decrease in VAS scores was statistically significant after the evaluation at 12 th h in all groups. Total morphine consumption (morphine concentration = 0.2 mg/ml in group paracetamol (72.3 ± 38.0 ml and dexketoprofen trometamol (69.3 ± 24.1 ml was significantly lower than group placebo (129.3 ± 22.6 ml (P < 0.001. Global satisfaction scores of the patients in group placebo was significantly lower than group dexketoprofen trometamol after surgery and the increase in global satisfaction score was significant only in group placebo. Conclusion: Dexketoprofen trometamol and Paracetamol didn′t cause significant change on pain scores, but increased patients′ comfort. Although total morphine consumption was significantly decreased by both drugs, the incidence of nausea and vomiting were similar among the groups. According to results of the present study routine addition of dexketoprofen trometamol and paracetamol to patient controlled analgesia morphine after hysterectomies is not

Full Text Available Background: Intravenous patient-controlled analgesia (PCA with morphine is commonly used for post-operative pain after major surgery. Ketamine has analgesic property at lower doses, and in combination with opioids it could have synergistic effect. The aim of this study is to determine effects of the addition of ketamine to morphine for PCA after orthopedic surgery. Materials and Methods: In this double-blind randomized clinical trial, 60 patients were randomly allocated to receive PCA consisting: Group 1 (morphine 0.2 mg/ml, Group 2 (morphine 0.2 mg/ml + ketamine 1 mg/ml, and Group 3 (morphine 0.1 mg/ml + ketamine 2 mg/ml. In this, anesthesiologists managed study, patients had orthopedic surgery. Assessments were made at 24 h and 48 h post-operatively. Visual analog scale (VAS was used for recording pain score. PCA morphine use was recorded at 24 h and 48 h. VAS scores over 48 h were analyzed with analysis of variance for repeated measures. Significance level was taken as 0.05. Results: There is no significant difference between demographic information of the three groups ( P > 0.05. Control of pain in Group 2 and Group 3 was better than in Group 1 (only morphine ( P = 0.001 but there was no significant difference between Group 2 and Group 3 ( P > 0.05. Rate of narcotic consumption in groups 2 and 3 was significantly lower than Group 1 ( P < 0.05. Conclusion: After orthopedic surgery, the addition of ketamine to morphine for intravenous PCA was superior to Intravenous PCA opioid alone. The combination induces a significant reduction in pain score and cumulative morphine consumption.

Resistance to recombinant erythropoietin (rEPO) in hemodialysis patients may be due to inadequate iron recruitment and defect in iron use. In this cross over randomized clinical trial, 30 hemodialysis patients with serum ferritin levels of ≥500 ng/ml, hemoglobin ≤11.0 g/dl, and transferrin saturation (TSAT) of 20% or less were administrated intravenous iron (50-100 mg/wk) and rEPO (120-360 U/kg/wk) for 6 months. Patients were excluded if there was a clear explanation for rEPO hyporesponsiveness. Patients were divided into two groups. Group1 received standard care and 500 mg of intravenous ascorbic acid (IVAA) with each dialysis session in the first week of each month for a total of 3 months. Group 2 received standard care only. After 2 month washout period, groups were crossed over. Each month hemoglobin (Hb) was assessed. Iron, TIBC (transferrin iron binding capacity), TSAT, iPTH (intact parathyroid hormone), liver enzymes, albumin and cholesterol levels were measured every 3 months. After 3 months of intervention, Hb significantly increased from 10.11 to 12.19 g/dl (P <0 0.001; 95% confidence interval [CI] 2.7-1.4) and TSAT increased from 18.9 to 28.1% (P = 0.008; 95% CI 0.09-3), while ferritin and serum iron declined significantly from 1391 to 938 ng/ml (P = 0.001; 95% CI 216-689), 97.2 to 64.6 (P = 0.001; 95% CI 14.8-50.4) in the study group. Change of Hb over time in IVAA group was significant (P < 0.0005). There were significant differences between two groups in change of Hb level over time (P < 0.0005) and treatment effect (P = 0.002). Baseline laboratory tests were similar in the two groups and there was no carry over effect at phase 2. We showed that low amount of IVAA could reduce ferritin level and enhance Hb and TSAT, suggesting improved iron utilization.

Insulin resistance (IR) may not only increase stroke risk, but could also contribute to aggravate stroke prognosis. Mainly through a derangement in endogenous fibrinolysis, IR could affect the response to intravenous thrombolysis, currently the only therapy proved to be efficacious for acute ischemic stroke. We hypothesized that high IR is associated with more persistent arterial occlusions and poorer long-term outcome after stroke thrombolysis. We performed a prospective, observational, longitudinal study in consecutive acute ischemic stroke patients presenting with middle cerebral artery (MCA) occlusion who received intravenous thrombolysis. Patients with acute hyperglycemia (≥155 mg/dL) receiving insulin were excluded. IR was determined during admission by the homeostatic model assessment index (HOMA-IR). Poor long-term outcome, as defined by a day 90 modified Rankin scale score ≥ 3, was considered the primary outcome variable. Transcranial Duplex-assessed resistance to MCA recanalization and symptomatic hemorrhagic transformation were considered secondary end points. A total of 109 thrombolysed MCA ischemic stroke patients were included (43.1% women, mean age 71 years). The HOMA-IR was higher in the group of patients with poor outcome (P = 0.02). The probability of good outcome decreased gradually with increasing HOMA-IR tertiles (80.6%, 1st tertile; 71.4%, 2nd tertile; and 55.3%, upper tertile). A HOMA-IR in the upper tertile was independently associated with poor outcome when compared with the lower tertile (odds ratio [OR] 8.54 [95% CI 1.67-43.55]; P = 0.01) and was associated with more persistent MCA occlusions (OR 8.2 [1.23-54.44]; P = 0.029). High IR may be associated with more persistent arterial occlusions and worse long-term outcome after acute ischemic stroke thrombolysis.

However, research concerning POD in IVPCA patients is limited. Objective: We aimed to determine the incidence, risk factors, and phenomenological characteristics of POD in patients receiving IVPCA. Methods: A prospective, cohort study was conducted in post-general anesthesia IVPCA patients aged ≥60 years. POD was measured by the Nursing Delirium Screening Scale (NuDESC; 0–10. Delirium, pain severity at rest and/or on movement, and side effects of IVPCA during 3 postoperative days were examined twice-daily by the acute pain service team. Pain severity is measured by an 11-point verbal numerical rating scale (11-point VNRS (0–10. An 11-point VNRS >3 was considered inadequate pain relief. If POD (detected by NuDESC ≥1 is suspected, consulting a neurologist or a psychiatrist to confirm suspected POD is required. Results: In total, 1,608 patients were included. The incidence rate of POD was 2.2%. Age ≥70 years and American Society of Anesthesiologists physical status >III were the risk factors of POD in IVPCA patients. Approximately three-quarters of all POD cases occurred within the first 2 postoperative days. For pain at rest, patients with inadequate pain relief had significantly greater rates of POD than patients with adequate pain relief (day 1, 8.4% vs 1.5%, P<0.001; day 2, 9.6% vs 2.0%, P=0.028; day 3, 4.1% vs 2.1%, P=0.412.

Regarding the use of intravenous lidocaine in fibromyalgia, there are no well-controlled studies. This study aimed to evaluate the effect of intravenous lidocaine on pain intensity, clinical manifestations and plasma levels of interleukin (IL)-1, IL-6, and IL-8 in fibromyalgia patients. In a randomized double-blind study, group 1 patients received 240 mg of lidocaine in 125 mL of saline solution, while group 2 patients received 125 mL of saline, both once a week for 4 weeks (T1, T2, T3 and T4). All patients received amitriptyline. The following were assessed: pain intensity before treatment (T0) and at 1, 2, 3, 4 and 8 weeks after treatment; clinical manifestations; the fibromyalgia impact questionnaire (FIQ) before and at 4 and 8 weeks after; the levels of IL 1, 6 and 8 before and at 4 and 8 weeks after treatment. Lower pain intensity was observed in the lidocaine group at T2, with no difference at the other time points. There was a reduction in pain intensity in both groups. The use of paracetamol and tramadol and plasma levels of IL-1, IL-6 and IL-8 did not differ between the groups. Clinical manifestations and side effects did not differ between groups. The combination of 240 mg of intravenous lidocaine (once a week for 4 weeks) with 25 mg of amitriptyline for 8 weeks had no meaningful impact in fibromyalgia patients. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

Recent results and future prospects of dynamic intravenous coronary angiography using synchrotron radiation

International Nuclear Information System (INIS)

Ohtsuka, Sadanori

1999-01-01

We have developed a dynamic intravenous coronary angiography (IVCAG) by using synchrotron radiation (SR) as a less invasive and more easy examination in place of CAG. Twelve patients suspected to have angina pectoris underwent IVCAG at the clinic in the National Laboratory for High Energy Accelerator Research Organization (KEK). The patients received an intravenous injection of 40m/of contrast agent, and then irradiation was performed with a wide (130 mm x 80 mm) and monochromatic (35 KeV) X-ray beam. Images were acquired with an image intensifier and recorded with a digital fluorography system as dynamic angiography at 30 or 10 images/sec. IVCAG was repeated in 2 or 3 projections. In all patients, the dynamic images permitted clear visualization of the coronary arteries and enabled evaluation of coronary anatomy. Two patients were diagnosed to have coronary stenosis by IVCAG and were confirmed by conventional CAG. The total irradiation doses used for IVCAG were less than those for conventional angiography. Although the image definition obtained with dynamic IVCAG was somewhat less than that of conventional CAG and needs to be improved, the IVCAG can be easily used for the evaluation of coronary arteries and may be clinically used for screening and follow-up of coronary artery disease. In future, the improvement of imaging system, such as increased intensity of synchrotron radiation and high sensitivity in imaging detector, will make more advance in image quality. (author)

Contrast agent choice for intravenous coronary angiography

Zeman, H.D.; Siddons, D.P.

1989-01-01

The screening of the general population for coronary artery disease would be practical if a method existed for visualizing the extent of occlusion after an intravenous injection of contrast agent. Measurements performed with monochromatic synchrotron radiation x-rays and an iodine containing contrast agent at the Stanford Synchrotron Radiation Laboratory have shown that such an intravenous angiography procedure would be possible with an adequately intense monochromatic x-ray source. Because of the size and cost of synchrotron radiation facilities it would be desirable to make the most efficient use of the intensity available, while reducing as much as possible the radiation dose experienced by the patient. By choosing contrast agents containing elements with a higher atomic number than iodine, it is possible to both improve the image quality and reduce the patient radiation dose, while using the same synchrotron source. By using Si monochromator crystals with a small mosaic spread, it is possible to increase the x-ray flux available for imaging by over an order of magnitude, without any changes in the storage ring or wiggler magnet. The most critical imaging task for intravenous coronary angiography utilizing synchrotron radiation x-rays is visualizing a coronary artery through the left ventricle or aorta which also contains a contrast agent. Calculations have been made of the signal to noise ratio expected for this imaging task for various contrast agents with atomic numbers between that of iodine and bismuth

Full Text Available Introduction: To assess characteristics, satisfaction, and disposition of emergency department (ED patients who successfully received ultrasound (US-guided peripheral intravenous (IV access. Methods: This is a prospective observational study among ED patients who successfully received US-guided peripheral IV access by ED technicians. Nineteen ED technicians were taught to use US guidance to obtain IV access. Training sessions consisted of didactic instruction and hands-on practice. The US guidance for IV access was limited to patients with difficult access. After successfully receiving an US-guided peripheral IV, patients were approached by research assistants who administered a 10-question survey. Disposition information was collected after the conclusion of the ED visit by accessing patients’ electronic medical record. Results: In total, 146 surveys were completed in patients successfully receiving US-guided IVs. Patients reported an average satisfaction with the procedure of 9.2 of 10. Forty-two percent of patients had a body mass index (BMI of greater than 30, and 17.8% had a BMI of more than 35. Sixty-two percent reported a history of central venous catheter placement. This patient population averaged 3 ED visits per year in the past year. Fifty-three percent of the patients were admitted. Conclusion: Patients requiring US-guided IVs in our ED are discharged home at the conclusion of their ED visit about half of the time. These patients reported high rates of both difficult IV access and central venous catheter placement in the past. Patient satisfaction with US-guided IVs was very high. These data support the continued use of US-guided peripheral IVs in this patient population. [West J Emerg Med. 2011;12(4:475–477.

By using intravenous misonidazole, a hypoxic cell radiosensitizer, the authors attempted to test the hypothesis of hypoxia as the basis of the relatively poor results seen with radiation therapy in the treatment of carcinoma of the thoracic esophagus. As the peripheral neuropathy of misonidazole was well recognized, they felt that an adequate dose of misonidazole could be given approximately ten times before peripheral neuropathy would necessitate its discontinuation. Because of a desire to maximize any possible effects of radiosensitization, it was decided to administer misonidazole with each fraction of radiation, attempting to deliver curative radiation therapy with only ten fractions of radiation. The authors thus devised a scheme of radiation consisting of 400 rad twice a week for 5 weeks, a total of 4000 rad. Originally the attempt was made to utilize preoperative radiation therapy and assess the histologic specimens for efficacy. However, major pulmonary toxicity caused revision of that plan. Twenty six patients were treated with radiotherapy alone without surgery, 12 of the patients being randomized to receive intravenous misonidazole with 10 fractions of 400 rad each. In terms of partial response, complete response, local control, and long-term survival, there was no suggestion of any benefit of intravenous misonidazole in these patients. As a consequence, although the number of study patients was small, the investigation was discontinued. Possible explanations for the failure to demonstrate any benefit of misonidazole are discussed

Transdermal electroporation has become one of the most promising noninvasive methods for drug administration, with greatly increased transport of macromolecules through the skin. The cecal-contracting effects of repeated transdermal electroporation delivery and intravenous administration of neostigmine were compared in anesthetized rats. The cecal contractions were detected with implantable strain gauge sensors, and the plasma levels of neostigmine were followed by high-performance liquid chromatography. Both intravenously and EP-administered neostigmine (0.2-66.7 μg/kg) increased the cecal contractions in a dose-dependent manner. For both the low doses and the highest dose, the neostigmine plasma concentrations were the same after the two modes of administration, while an insignificantly higher level was observed at a dose of 20 μg/kg after intravenous administration as compared with the electroporation route. The contractile responses did not differ significantly after the two administration routes. The results suggest that electroporation-delivered neostigmine elicits action equivalent to that observed after intravenous administration as concerning both time and intensity. Electroporation permits the delivery of even lower doses of water-soluble compounds through the skin, which is very promising for clinical practice.

Intravenous Immunoglobulin G (IVIG) therapy has been used as a component of the treatment of hemolytic disease of the newborn. There is still no consensus on its use in ABO hemolytic disease of the newborn routinely. The aim of this study is to determine whether administration of IVIG to newborns with ABO incompatibility is necessary. One hundred and seventeen patients with ABO hemolytic disease and positive Coombs test were enrolled into the study. The subjects were healthy except jaundice. Infants were divided into two groups: Group I (n = 71) received one dose of IVIG (1 g/kg) and LED phototherapy whereas Group II (n = 46) received only LED phototherapy. One patient received erythrocyte transfusion in Group I, no exchange transfusion was performed in both groups. Mean duration of phototherapy was 3.1 ± 1.3 days in Group I and 2.27 ± 0.7 days in Group II (p hemolytic disease. Meticulus follow-up of infants with ABO hemolytic disease and LED phototherapy decreases morbidity. IVIG failed to show preventing hemolysis in ABO hemolytic disease.

Anaphylaxis following intravenous paracetamol: the problem is the solution.

Science.gov (United States)

Jain, S S; Green, S; Rose, M

2015-11-01

Paracetamol is a ubiquitous analgesic and antipyretic that is widely administered, including by anaesthetists. Immediate hypersensitivity reactions to intravenous paracetamol are particularly rare. We report two cases involving four separate episodes of anaphylaxis to intravenous paracetamol in different perioperative settings without a past history of intolerance to the oral form. The allergological investigations are described, during which it became evident that both patients were allergic to an excipient (mannitol) present in the formulation and that neither was allergic to the principal agent (paracetamol). The importance of referral and investigation of perioperative drug reactions is underscored by these two cases.

Full Text Available Advanced pulmonary disease is an unusual consequence of the intravenous injection of oral medications, usually developing over a period of several years. A number of patients with this condition have undergone lung transplantation for respiratory failure. However, a history of drug abuse is often considered to be a contraindication to transplantation in the context of limited donor resources. A patient with pulmonary talc granulomatosis secondary to intravenous methylphenidate injection who underwent successful lung transplantation and subsequently presented with recurrence of the underlying disease in the transplanted lung 18 months after transplantation is reported.

Combined use of intravenous anesthetics and hypothermia in treating refractory status epilepticus

Guo-ping REN

2015-11-01

Full Text Available The primary choice of treating refractory status epilepticus (RSE is intravenous anesthetics, but the seizures of some patients can not get a good control. Thus, other therapies must be combined. Hypothermia not only can terminate seizures, but also play a part in brain protection. Though combined use of intravenous anesthetics and hypothermia is not a regular clinical scheme, the favorable effect has been proved by a lot of clinical research. This paper mainly focuses on the dose of intravenous anesthetics, the time, temperature and procedure of hypothermia, the indications and contraindications of combined therapy, and so on. DOI: 10.3969/j.issn.1672-6731.2015.11.006

Full Text Available Background: Cesarean section is one of the common surgeries of women. Acute post-operative pain is one of the recognized post-operative complications. Aims: This study was planned to compare the effects of suppositories, indomethacin, diclofenac and acetaminophen, on post-operative pain and opioid usage after cesarean section. Materials and Methods: In this double-blind clinical trial study, 120 candidates of cesarean with spinal anesthesia and American Society of Anesthesiologists (ASA I-II were randomly divided into four groups. Acetaminophen, indomethacin, diclofenac, and placebo suppositories were used in groups, respectively, after operation and the dosage was repeated every 6 h and pain score and opioid usage were compared 24 h after the surgery. The severity of pain was recorded on the basis of Visual Analog Scale (VAS and if severe pain (VAS > 5 was observed, 0.5 mg/kg intramuscular pethidine had been used. Statistical Analysis Used: The data were analyzed in SPSS software version 15 and analytical statistics such as ANOVA, Chi-square, and Tukey′s honestly significant difference (HSD post-hoc. Results : Pain score was significantly higher in control group than other groups, and also pain score in acetaminophen group was higher than indomethacin and diclofenac. The three intervention groups received the first dose of pethidine far more than control group and the distance for diclofenac and indomethacin were significantly longer (P < 0.001. The use of indomethacin, diclofenac, and acetaminophen significantly reduces the amount of pethidine usage in 24 h after the surgery relation to control group. Conclusions : Considering the significant decreasing pain score and opioid usage especially in indomethacin and diclofenac groups rather than control group, it is suggested using of indomethacin and diclofenac suppositories for post-cesarean section analgesia.

We proposed to determine the proportion of patients who refuse to undergo intravenous contrast administration and the factors that influence their refusal. Our series consisted of 442 patients who were supposed to undergo imaging studies involving the intravenous injection of an iodine contrast. In a personal interview, the patients were issued a questionnaire specifically designed for this study. The following parameters were recorded: sex, age, inpatient or outpatient status, medical history available, person who informed them about the procedure, person signing the informed consent (patient or other) , highest academic degree, attitude toward receiving the information and degree of concern after reading and signing the consent form. In our series 8.6% of the patients (95% confidence interval: 6-11.2) refused to sign the informed consent form. In addition, there were a number of patients who delayed the procedure or hindered the daily work schedule by some other means. When the relationship between each of the variables studied and refusal to sign the consent form was assessed, significant associations were observed between the latter and the academic level of the patient, his or her degree of concern and having received the information from a trained person. There was also a nearly significant trend toward the association between refusal and the patient's background. Relatively few patients refuse to sign the informed consent to receive intravenous contrast administration but this negative decision interferes with the health care practice. It is possible to identify certain correctable factors that influence the patient in this respect. (Author) 13 refs.

Intravenous dynamic nucleography of the brain

International Nuclear Information System (INIS)

Rosenthall, L.

1972-01-01

The advent of stationary imaging devices has created interest in studying cerebral blood flows and transits with diffusible and nondiffusible radioactive indicators. Much of this has disclosed interesting pathophysiology, but not necessarily of significant diagnostic import to include in routine patient workup. The conventional static brain scan is one of the more useful tests in the nuclear medicine armamentarium for uncovering and localizing intracranial disease. Unfortunately, it does not as a rule clearly distinguish cerebral vascular accidents, neoplasms, arteriovenous malformations, and so forth, which is important from the standpoint of patient management. Aside from clinical impressions a diagnosis is often based on the appearance of the radiocontrast angiogram, which is not always desirable because of the implicit hazards. Thus it is incumbent upon investigators to search for innocuous intravenous methods of identifying the various intracranial afflictions. Intravenous 99 /sup m/Tc-pertechnetate comparisons of brain hemisphere perfusion as a routine complement to static brain imaging are useful. Estimations of disparate radioactive transits are made qualitatively from serial 4 to 5 sec exposure scintiphotographs. (U.S.)

2002-01-01

Full Text Available With the aim of determining the possible toxicity of amitraz after its prolonged use in horses, six English Thoroughbred horses received intravenous injections of amitraz (0.05, 0.10 or 0.15 mg/kg weekly for four months, constituting the experimental group. Eight other animals (control group, via the same route following the same drug administration schedule and period of time, received the vehicle, dimethylformamide. At the end of this period, blood was collected from all the animals, and a comparison was made of the means of the values obtained for the various blood analyses: complete hemogram, alkaline phosphatase, gamma-glutamyltransferase, blood urea nitrogen, lactate dehydrogenase, aspartate aminotransferase, creatine phosphokinase, glucose, albumin, total protein, creatinine, Na+ , K+, Cl- and CO2. The results for the biochemical characteristics showed that only the mean value for urea of the animals submitted to treatment with amitraz was significantly different than the mean value obtained for the control group. The analyses of the hematological characteristics showed that no significant differences between groups were observed. Similarly, the measurement of blood electrolyte levels demonstrated that long-term treatment with amitraz did not cause significant changes in the variables analyzed. The results indicate that amitraz, given in the doses employed in this study, did not show signs of inducing toxic effects in vital organs, even after prolonged administration.

Cerebral coenurosis is a disease of the central nervous system in sheep and goats, and is usually fatal unless surgical relief is provided. Information regarding neuroanaesthesia in veterinary medicine in goats is scant. We describe anaesthetic management of an intact female goat (2 years; 16 kg) presented for craniectomy. The goat was sedated with xylazine (0.05 mg kg -1 , i.m.) and morphine (0.05 mg kg -1 , i.m.). General anaesthesia was induced 20 min later with propofol and maintained with a constant rate infusion of propofol (0.2 mg kg -1  min -1 ). A cuffed endotracheal tube was placed and connected to a rebreathing (circle) system and mechanical ventilation with 100% oxygen was initiated. A bolus of lidocaine (1 mg kg -1 ), midazolam (0.25 mg kg -1 ) and fentanyl 2.5 μg kg -1 was delivered via the intravenous route followed immediately by a constant rate infusion of lidocaine (50 μg kg -1  min -1 ), midazolam (0.15 mg kg -1  h -1 ) and fentanyl (6 μg kg -1  h -1 ) administered via the intravenous route throughout surgery. Craniectomy was undertaken and the goat recovered uneventfully. Total intravenous anaesthesia with propofol, lidocaine, fentanyl and midazolam could be an acceptable option for anaesthesia during intracranial surgery in goats.

Verification of proper placement of an intravenous catheter may not always be simple. We evaluated the auscultation technique for this purpose. Twenty healthy volunteers were randomized for 18G catheter inserted intravenously either in the right (12) or left arm (8), and subcutaneously in the opposite arm. A standard stethoscope was placed over an area approximately 3 cm proximal to the tip of the catheter in the presumed direction of the vein to grade on a 0-6 scale the murmur heard by rapidly injecting 2 mL of NaCl 0.9% solution. The auscultation was evaluated by a blinded staff anesthesiologist. All 20 intravenous injection were evaluated as flow murmurs, and were graded an average 5.65 (±0.98), whereas all 20 subcutaneous injections were evaluated as either crackles or no sound, and were graded an average 2.00 (±1.38), without negative results. Sensitivity was calculated as 95%. Specificity and Kappa could not be calculated due to an empty false-positive group. Being simple, handy and noninvasive, we recommend to use the auscultation technique for verification of the proper placement of an intravenous catheter when uncertain of its position. Data obtained in our limited sample of healthy subjects need to be confirmed in the clinical setting.

HEADPLAY Personal Cinema System Facilitates Intravenous Cannulation in Children: A Randomized Controlled Trial

2013-01-01

Full Text Available HEADPLAY personal cinema system (PCS is a portable visual headset/visor through which movie clips may be viewed. We studied the use of HEADPLAY PCS as a distraction tool in facilitating intravenous cannulation in children undergoing anaesthesia. 60 children were enrolled into the study and randomized into 2 groups. EMLA local anaesthetic cream was used to reduce the pain associated with intravenous cannulation. Children in group 1 wore the HEADPLAY visor whereas children in group 2 were subject to conventional distraction therapy. Children were asked to rate their anxiety, pain, and satisfaction scores after intravenous cannulation. Periprocedural anxiety was also determined using the modified Yale Preoperative Anxiety Scale (mYPAS. There were no statistically significant differences in terms of pain and anxiety scores between the 2 groups. Although the satisfaction score of the children in the HEADPLAY PCS group was marginally higher compared to the conventional group, this did not hit statistical significance. 86.6% of children in group 1 reported that they would want to use the visor again for their next intravenous cannulation. We conclude that HEADPLAY PCS is a distraction tool that is acceptable to most children and can contribute towards satisfaction of the intravenous cannulation process in children.

This prospective study aimed to compare the intraosseous (IO) and intravenous (IV) effects of propofol on selected blood parameters and physiological variables during general anesthesia in rabbits. Thirty New Zealand White rabbits were studied. Six rabbits received IV propofol (group 1) and another 6 rabbits, were injected propofol intraosseously (Group 2) for 30 minutes (experimental groups). Rabbits of the third and fourth groups received IV and IO normal saline at the same volume given to the experimental groups, respectively. In the fifth group IO cannulation was performed but neither propofol nor normal saline were administered. Blood profiles were assayed before induction and after recovery of anesthesia. Heart and respiratory rates, rectal temperature, saturation of peripheral oxygen and mean arterial blood pressure were recorded. Heart rate increased significantly 1 to 5 minutes after induction of anesthesia in experimental groups (P anesthesia in rabbits with limited vascular access.

Nager, Alan L; Wang, Vincent J

2010-02-01

The purpose of this study is to test the efficacy of ultrarapidly infused vs rapidly infused intravenous (IV) hydration in pediatric patients with acute gastroenteritis and moderate dehydration. Patients 3 to 36 months, with vomiting and/or diarrhea and moderate dehydration, were eligible. Subjects were randomly assigned "ultra" (50 mL/kg normal saline for 1 hour) vs "standard" (50 mL/kg normal saline for 3 hours) after failing an oral fluid challenge. Subjects were weighed and had serum electrolyte testing, and urine was obtained before/after IV hydration. Input/output and vital signs were tabulated hourly during the study. Subjects were discharged after fulfilling specified criteria. A follow-up questionnaire was completed 24 hours after discharge. Comparison data included success and timing of rehydration, number of patients who returned and/or were admitted, output during the rehydration period, laboratory differences, and serious complications. Eighty-eight of 92 subjects completed the study: 45 ultra and 43 standard. Four patients failed treatment (1 ultra and 3 standard), were hospitalized, and excluded from the study. Groups were similar regarding sex, days of symptoms, episodes of vomiting/diarrhea before treatment, capillary refill time, tears, and vital signs and laboratory results. No subject had evidence of serious complications. Ninety-one percent of subjects completed the follow-up questionnaire. Seven ultra and 6 standard subjects returned. Six ultra subjects received oral fluid, one received IV fluid, and all were discharged. Five standard subjects received oral fluid, one received IV fluid, and all were discharged. Based on this pilot study, ultrarapid hydration for 1 hour preliminarily appears to be an efficacious alternative to standard rapid hydration for 3 hours and improves emergency department throughput time.

2018-03-01

Full Text Available Introduction: Our objective was to describe dosing, duration, and pre- and post-infusion analgesic administration of continuous intravenous sub-dissociative dose ketamine (SDK infusion for managing a variety of painful conditions in the emergency department (ED. Methods: We conducted a retrospective chart review of patients aged 18 and older presenting to the ED with acute and chronic painful conditions who received continuous SDK infusion in the ED for a period over six years (2010–2016. Primary data analyses included dosing and duration of infusion, rates of pre- and post-infusion analgesic administration, and final diagnoses. Secondary data included pre- and post-infusion pain scores and rates of side effects. Results: A total of 104 patients were enrolled in the study. Average dosing of SDK infusion was 11.26 mg/hr, and the mean duration of infusion was 135.87 minutes. There was a 38% increase in patients not requiring post-infusion analgesia. The average decrease in pain score was 5.04. There were 12 reported adverse effects, with nausea being the most prevalent. Conclusion: Continuous intravenous SDK infusion has a role in controlling pain of various etiologies in the ED with a potential to reduce the need for co-analgesics or rescue analgesic administration. There is a need for more robust, prospective, randomized trials that will further evaluate the analgesic efficacy and safety of this modality across a wide range of pain syndromes and different age groups in the ED.

Sharifi, J; Ghavami, F; Nowrouzi, Z; Fouladvand, B; Malek, M; Rezaeian, M; Emami, M

1985-01-01

A controlled, randomised trial comparing the results of oral rehydration therapy with those of intravenous fluid treatment in 470 children with severe gastroenteritis was undertaken. The oral rehydration therapy was divided into two phases--a rehydration phase that used high sodium isotonic fluid at 40 ml/kg per hour and a maintenance phase using low sodium isotonic fluid (sodium 40, potassium 30, bicarbonate 25, chloride 45, and dextrose 130 mmol/l). The results indicate that oral rehydration treatment, used according to this protocol, is successful in treating severe diarrhoea and dehydration, and has considerable advantages over intravenous fluid therapy in reducing complications associated with the treatment of hypernatraemia, in promoting rapid correction of hypokalaemia and acidosis, in decreasing the duration of diarrhoea, and in promoting a greater weight gain at hospital discharge.

2016-09-01

Full Text Available Introduction: Post Dural puncture headache is still a common complication among young women undergone cesarean section, although use of small size spinal needles reduced its prevalence. Several methods have been suggested for prevention and treatment of this side effect; such as complete bed rest, hydration, non-opioid analgesics, caffeine, codeine, which none of them proved to be totally effective. The last option would be epidural blood patch, if headache persist. The aim of this study was evaluation the efficacy of intravenous propofol on post dural puncture headache incidence after cesarean section. Methods: In a randomized clinical trial 120 patients aged 18-45 years old in American Society of Anesthesiologist (ASA class I or II, who had no history of headache, analgesic consumption, substance abuse and drug addiction, candidate for elective cesarean section, were randomly assigned into intervention (propofol and control groups. The anesthesia method for both groups was precisely the same. After spinal anesthesia in the first group 30µg/kg/min of intravenous propofol have been infused slowly. Then at 1, 6, 18, 24 hours and 2nd to 7th days after surgery, anesthesiologist asked groups for presence or absence of headache. The data analyzed with SPSS 16.0 software. Results: Headache incidence rate in the group who receiving propofol was significantly reduced (P.V=0.001. Conclusion: This study showed that 30µg/kg/min of intravenous propofol caused reduced the incidence of post spinal headache in young women undergone elective cesarean section.

The aim is to evaluate the preliminary efficacy and side effects of paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy in combination with cisplatin hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) as postoperative adjuvant therapy for patients of locally advanced gastric cancer (GC) at high risk for recurrence after curative resection. Four GC patients who underwent radical gastrectomy with D2 lymphadenectomy were enrolled. All patients received paclitaxel 135 mg/m2 on day 1, 5-FU 500 mg/m2 on days 1-5, LV 200 mg/m2 on days 1-5 intravenous chemotherapy, cisplatin 75 mg/m2 on day 5, and HIPEC one month after surgery. It was repeated at 3 weeks intervals and at least two cycles administered. A total of 181 cycles of chemotherapy were administered (median, 4 cycles). The median disease free survival time of patients was 40.8 months. The median overall survival time was 48.0 months. The one-, two-, and three-year recurrence rates were 14.6%, 26.8%, and 46.3%, respectively. The main relapse patterns were remnant GC and metastases of retroperitoneal lymph nodes. The morbidity of grade 3 and 4 toxicities of myelosuppression, nausea/ vomiting were less than 10%. The side effects of grade 1 and 2 of hematologic toxicity, nausea and vomiting, abnormal function of liver, kidney or cardiac, fatigue and neurotoxicity were well tolerated. Cisplatin HIPEC combined with paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy regimen could improve the survival rate and decrease the postoperative recurrence of locally advanced GC.

Rathsmann, P.; Jacobs, G.F.; Mueller, R.D.

2004-01-01

Purpose: We examined the subjective compatibility of elderly patients who received the intravenous contrast medium Iopentol (Imagopaque trademark 300). In addition, objective data were acquired to show possible interactions between contrast media and organ systems in old patients. Methods and materials: A CT scan with intravenous application of contrast media was performed on 132 patients ranging in age from 75 to 96 years. The patients were questioned about their individual sensations. In addition, blood pressure, creatinine and CT-densitometry were acquired as objective date. Results: The patients' individual sensations and clinical data show a very low rate of complications. Mild allergic reactions were noticed in two patients. No severe anaphylactic reactions were encountered. Statistically significant changes in blood pressure before and after administration of the contrast medium were not observed. The serum creatinine concentration was unchanged after application of contrast media. For CT-densitometry, the patients were divided into two groups, one group with patients 75-84 years and the other group with patients 85-96 years of age. CT-densitometry showed no age-related differences. The protocol of contrast administration resulted in excellent opacification of the examined regions, only the liver did not enhance in some cases before the opacification of the portal vein. Conclusion: It is shown that old age alone is no reason to withhold contrast media containing iodine when performing CT. For the evaluation of the liver, however, the peculiarities of old age have to be taken into account and the interval between injection of the contrast medium and beginning of the spiral-CT has to be extended.

Full Text Available BACKGROUND Postoperative pain after open cholecystectomy is associated with respiratory dysfunction, increased stress response and prolonged hospital stay. We compare intravenous paracetamol (7.5 mg/kg plus intercostal nerve block with local anaesthetic ropivacaine 0.5% to intravenous paracetamol (15 mg/kg on pain control after open cholecystectomy. MATERIALS AND METHODS 140 patients, who underwent for open cholecystectomy, were randomly divided into two groups of 70. The patients were randomly allocated to any of the following two groups depending upon the drug used for analgesia (Group P or Group I Intravenous paracetamol 15 mg/kg was given to patients of group P and paracetamol 7.5 mg/kg with Intercostal nerve block in right side 6-10 intercostal nerves with 2 ml local anaesthetic ropivacaine 0.5% in each space was given to patients of group I just after intubation before incision. When the patients were transferred to postoperative recovery room, intensity of pain was recorded by response from the patients using 100 mm linear visual analogue scale ranging from 0 to 100. The pain scoring was done in the immediate postoperative period (when the patient was able to communicate in the post anaesthesia care unit, at 30 minutes, 1 hr. then hourly up to 24 hrs. till patient complained of pain with VAS score 40 or more. RESULTS The severity of pain in VAS score was lower in immediate postoperative period, at 30 minutes, 1 hour and 2 hours postoperatively in group I than the group P and those were statistically significant (p<0.001. Duration of analgesia also significantly lower in group I. Mean duration of analgesia in group P is 161.9 ± 42.6 min and in group I is 241.3 ± 44.2 min (p<0.001. CONCLUSION Adding Intercostal nerve block to intravenous infusion of Paracetamol infusion (7.5 mg/kg is better than sole intravenous infusion of Paracetamol (15 mg/kg in controlling pain severity even after reducing dose of paracetamol after open

Cost-Effectiveness of Intravenous Proton Pump Inhibitors in High-Risk Bleeders

Directory of Open Access Journals (Sweden)

Sander Veldhuyzen van Zanten

2004-01-01

Full Text Available There is unequivocal evidence that proton pump inhibitors (PPIs are currently the most effective acid suppressive agents available. Intravenous (IV formulations have been developed, although only IV pantoprazole is available in Canada. In patients presenting with serious upper gastrointestinal (GI bleeding due to duodenal or gastric ulcers, it has always been believed that IV administration of acid-lowering agents would improve clinical outcomes. The reason behind this thinking is twofold. First, there is in vitro evidence that formed clots are more stable at or near neutral pH (1. Second, by administering the agent intravenously, suppression of acid production is achieved much more quickly, thereby promoting more rapid healing of the ulcer and reducing the risk of persistent or recurrent bleeding. Interestingly and surprisingly, however, the data for intravenous H2-blockers have been disappointing (2. This failure to demonstrate clinical benefit has never been fully explained.

This case report describes the possible benefit of intravenous lipid emulsion in two patients surviving a severe intoxication with hydroxychloroquine in a dose that was previously considered to be lethal. The first case involves a 25-year-old female who ingested 17.5 grams of hydroxychloroquine, approximately one hour before presentation. An ECG showed QRS widening and the lab results showed hypokalaemia. She became unconscious, and developed hypotension and eventually apnoea. After intubation, supportive care consisted of norepinephrine and supplementation of potassium. Moreover, sodium bicarbonate and intravenous lipid emulsion were started to prevent cardiac toxicity. After these interventions, haemodynamic stability was established within a few hours. Although cardiomyopathy was confirmed, the patient recovered after two weeks. The second case concerns a 25-year-old male who took 5 grams of hydroxychloroquine. At presentation, two hours after intake, he showed QTc prolongation and hypokalaemia. The patient was treated with the usual supportive care and, although presentation to hospital was later, with intravenous lipid emulsion. Also this patient recovered. In conclusion, these cases show the benefit of supplemental intravenous lipid emulsion to prevent cardiac toxicity after a severe intoxication with hydroxychloroquine.

Hydroxocobalamin is a Food and Drug Administration-approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model. Our objective is to compare the time to return of spontaneous breathing in swine with acute cyanide-induced apnea treated with intravenous hydroxocobalamin, intravenous cobinamide, or saline solution (control). Thirty-three swine (45 to 55 kg) were intubated, anesthetized, and instrumented (continuous mean arterial pressure and cardiac output monitoring). Anesthesia was adjusted to allow spontaneous breathing with FiO2 of 21% during the experiment. Cyanide was continuously infused intravenously until apnea occurred and lasted for 1 minute (time zero). Animals were then randomly assigned to receive intravenous hydroxocobalamin (65 mg/kg), cobinamide (12.5 mg/kg), or saline solution and monitored for 60 minutes. A sample size of 11 animals per group was selected according to obtaining a power of 80%, an α of .05, and an SD of 0.17 in mean time to detect a 20% difference in time to spontaneous breathing. We assessed differences in time to death among groups, using Kaplan-Meier estimation methods, and compared serum lactate, blood pH, cardiac output, mean arterial pressure, respiratory rate, and minute ventilation time curves with repeated-measures ANOVA. Baseline weights and vital signs were similar among groups. The time to apnea and cyanide dose required to achieve apnea were similar. At time zero, mean cyanide blood and lactate concentrations and reduction in mean arterial pressure from baseline were similar. In the saline solution group, 2 of 11 animals survived compared with 10 of 11 in the hydroxocobalamin and cobinamide groups (Pcyanide concentrations became undetectable at the end of the study in both antidote-treated groups, and no statistically significant differences

Full Text Available Objective: To study the effect of insulin pump and continuous intravenous insulin on ketone body metabolism, blood gas indexes and stress state in patients with diabetic ketoacidosis. Methods: Patients with diabetic ketoacidosis who were treated in Meizhou Maternal and Child Heath Hospital between May 2014 and March 2017 were selected as the research subjects and randomly divided into the group A who received subcutaneous insulin infusion by insulin pump and the group B who received intravenous small-dose insulin injection by micropump. The indexes of ketone body, blood gas and stress were measured before and after treatment. Results: 12 h and 24 h after treatment, serum β-hydroxybutyrate, MDA, NE, ACTH and Cor contents of both groups of patients were significantly lower than those before treatment while pH, HCO3 - and base excess levels as well as serum SOD, GSH-Px, CAT and TAC contents were significantly higher than those before treatment, and serum β-hydroxybutyrate, MDA, NE, ACTH and Cor contents of group A were significantly lower than those of group B while pH, HCO3 - and base excess levels as well as serum SOD, GSH-Px, CAT and TAC contents were significantly higher than those of group B. Conclusion: Subcutaneous insulin infusion by insulin pump can improve ketone body metabolism, acidosis status and stress state in patients with diabetic ketoacidosis.

Cost-minimization analysis favours intravenous ferric carboxymaltose over ferric sucrose for the ambulatory treatment of severe iron deficiency.

Xavier Calvet

Full Text Available OBJECTIVE: Intravenous iron is widely used to treat iron deficiency in day-care units. Ferric carboxymaltose (FCM allows administration of larger iron doses than iron sucrose (IS in each infusion (1000 mg vs. 200 mg. As FCM reduces the number of infusions required but is more expensive, we performed a cost-minimization analysis to compare the cost impact of the two drugs. MATERIALS AND METHODS: The number of infusions and the iron dose of 111 consecutive patients who received intravenous iron at a gastrointestinal diseases day-care unit from 8/2007 to 7/2008 were retrospectively obtained. Costs of intravenous iron drugs were obtained from the Spanish regulatory agencies. The accounting department of the Hospital determined hospital direct and indirect costs for outpatient iron infusion. Non-hospital direct costs were calculated on the basis of patient interviews. In the pharmacoeconomic model, base case mean costs per patient were calculated for administering 1000 mg of iron per infusion using FCM or 200 mg using IS. Sensitivity analysis and Monte Carlo simulation were performed. RESULTS: Under baseline assumptions, the estimated cost of iron infusion per patient and year was €304 for IS and €274 for FCM, a difference of €30 in favour of FCM. Adding non-hospital direct costs to the model increased the difference to €67 (€354 for IS vs. €287 for FCM. A Monte Carlo simulation taking into account non-hospital direct costs favoured the use of FCM in 97% of simulations. CONCLUSION: In this pharmacoeconomic analysis, FCM infusion reduced the costs of iron infusion at a gastrointestinal day-care unit.

The medical applications of aptamers have recently emerged. We developed an antagonistic thioaptamer (ESTA) against E-selectin. Previously, we showed that a single injection of ESTA at a dose of 100 μg inhibits breast cancer metastasis in mice through the functional blockade of E-selectin. In the present study, we evaluated the safety of different doses of intravenously administered ESTA in single-dose acute and repeat-dose subacute studies in ICR mice. Our data indicated that intravenous administration of up to 500 μg ESTA did not result in hematologic abnormality in either study. Additionally, intravenous injection of ESTA did not affect the levels of plasma cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, GM-CSF, IFN-γ, and TNF-α) or complement split products (C3a and C5a) in either study. However, repeated injections of ESTA slightly increased plasma ALT and AST activities, in accordance with the appearance of small necrotic areas in the liver. In conclusion, our data demonstrated that intravenous administration of ESTA does not cause overt hematologic, organs, and immunologic responses under the experimental conditions. - Highlights: • Intravenous administration of ESTA was well tolerated. • ESTA up to 500 μg does not cause hematologic, organs, and immunologic responses. • ESTA-mediated hepatic abnormality was considered minor.

Full Text Available Obesity is a major global health issue. Obese patients develop metabolic syndrome, which is a cluster of clinical features characterized by insulin resistance and dyslipidemia. Its cardiac manifestation, diabetic cardiomyopathy, leads to heart failure. Bone marrow-derived multipotent mesenchymal stromal cells, also referred to as mesenchymal stem cells (MSC are envisioned as a therapeutic tool not only for cardiovascular diseases but also for other degenerative conditions. Our aim was to evaluate whether the intravenous administration of MSC modifies cardiac dysfunction in obese mice. To this end, C57BL/6 mice were fed a regular (normal or high-fat diet (obese. Obese animals received the vehicle (obese, a single dose (obese + 1x MSC or three doses (obese + 3x MSC of 0.5x10(6 syngeneic MSC. Two to three months following MSC administration, cardiac function was assessed by cardiac catheterization, at basal condition and after a pharmacological stress. Compared to normal mice, obese mice presented hyperglycemia, hyperinsulinemia, hypercholesterolemia and cardiac dysfunction after stress condition. Exogenous MSC neither improved nor impaired this cardiac dysfunction. Thus, intravenous administration of MSC has neutral effect on obesity-induced diabetic cardiomyopathy

Full Text Available Background: Propofol is one of the widely used intravenous (i.v. anaesthetics, although pain on injection still remains a considerable concern for the anaesthesiologists. A number of techniques has been tried to minimize propofol-induced pain with variable results. Recently, a 5-HT 3 antagonist, ondansetron pre-treatment, has been shown to reduce propofol-induced pain. The aim of our randomized, placebo-controlled, double-blinded study was to determine whether pre-treatment with intravenous granisetron, which is routinely used in our practice for prophylaxis of post-operative nausea and vomiting, would reduce propofol-induced pain. Methods: Eighty-two women, aged 18-50 years, American society of Anaesthesiologist grading (ASA I-II, scheduled for various surgeries under general anaesthesia were randomly assigned to one of the two groups. One group received 2 mL 0.9% sodium chloride while the other group received 2 mL granisetron (1 mg/mL, and were accompanied by manual venous occlusion for 1 min. Then, 2 mL propofol was injected through the same cannula. Patients were asked by a blinded investigator to score the pain on injection of propofol with a four-point scale: 0=no pain, 1=mild pain, 2=moderate pain, 3=severe pain. Results: Twenty-four patients (60% complained of pain in the group pre-treated with normal saline as compared with six (15% in the group pre-treated with granisetron. Pain was reduced significantly in the granisetron group (P<0.05. Severity of pain was also lesser in the granisetron group compared with the placebo group (2.5% vs. 37.5%. Conclusion: We conclude that pre-treatment with granisetron along with venous occlusion for 1 min for prevention of propofol-induced pain was highly successful.

Relapse of Neuromyelitis Optica Spectrum Disorder Associated with Intravenous Lidocaine

Full Text Available Lidocaine unmasks silent symptoms and eases neuropathic pain in multiple sclerosis patients; however, the effects of lidocaine in neuromyelitis optica have never been reported. We describe the case of a 59-year-old Japanese woman with neuromyelitis optica spectrum disorder who developed optic neuritis 1 day after intravenous lidocaine injection for treating allodynia. Her symptom seemed to result from a relapse of neuromyelitis optica induced by lidocaine administration, and not because of the transient effects of intravenous lidocaine administration. The possibility that lidocaine administration results in relapse of neuromyelitis optica due to its immunomodulating effects cannot be ruled out.

To evaluate if the pre-emptive administration of ketamine would potentiate the effect of intravenous morphine analgesia in the management of post-thoracotomy pain. This was a unicentre, double-blind, placebo-controlled, parallel-group, prospective study. Patients were randomly assigned to receive 1 mg/kg ketamine (ketamine group) or an equivalent dose of normal saline (placebo group) before thoracotomy in 1:1 ratio. All patients received postoperatively intravenous morphine administration as additional analgesic regimen. Primary end-point was the pain relief measured with Visual Analogue Scale at rest. The secondary end-points were the reduction of inflammatory response expressed by plasma C-reactive protein levels, the morphine consumption and the rate of side effects. The measurements were carried out 6, 12, 24, 36 and 48 hours postoperatively. A total of 75 patients were randomized of whom 38 were allocated to ketamine group and 37 to placebo group. Baseline characteristics were comparable. Ketamine compared with placebo group showed a significant reduction of pain scores (P = 0.01), C-reactive protein (P morphine consumption (P psychological side effects related to the use of ketamine were registered. The administration of ketamine before surgery may be an effective adjunct to intravenous morphine analgesia in acute post-thoracotomy pain management. In ketamine group, satisfaction of pain relief was significantly higher with a significant reduction of inflammatory response and morphine consumption compared with placebo group. Our results, if confirmed by larger studies, may be of clinical relevance in situations where epidural analgesia or other analgesic procedures different from systemic opioid analgesia are unavailable or contraindicated. © The Author 2015.

Full Text Available Gabapentin is a GABA analog which has the effect of anti hyperalgesia, anti allodynia, and anti nociceptive. This research was conducted in order to assess the effect of 600mg and 1,200 mg gabapentin given preoperatively to assess visual analogue scale (VAS score and reduction of pethidine requirement. The study was done by conducting a double blind randomized controlled trial on 38 patients, aged 18–65 years, with ASA physical status I–II. Patients were divided into two groups: 600 mg gabapentin and 1,200 mg gabapentin group. The quality of pain was assessed using VAS score. The results were statistically analyzed using Mann-Whitney Test with 95% confidence interval and considered significant if p value <0.05. From the results, the VAS values obtained at rest and during mobilization were significantly different (p<0.05. The 1,200 mg gabapentin group received less additional pethidine (10.5% vs 15.8%, although no significant difference was shown (p=0.631. The conclusion of this study is that administration of 1,200 mg gabapentin per oral pre operatively is better when compared to 600 mg in reducing post operative visual analog scale score in modified radical mastectomy. However, it do not reduce the need for analgesic significantly.

Risk factors are different for deep and lobar remote hemorrhages after intravenous thrombolysis.

Full Text Available Remote parenchymal haemorrhage (rPH after intravenous thrombolysis is defined as hemorrhages that appear in brain regions without visible ischemic damage, remote from the area of ischemia causing the initial stroke symptom. The pathophysiology of rPH is not clear and may be explained by different underlying mechanisms. We hypothesized that rPH may have different risk factors according to the bleeding location. We report the variables that we found associated with deep and lobar rPH after intravenous thrombolysis.This is a descriptive study of patients with ischemic stroke who were treated with intravenous thrombolysis. These patients were included in a multicenter prospective registry. We collected demographic, clinical and radiological data. We evaluated the number and distribution of cerebral microbleeds (CMB from Magnetic Resonance Imaging. We excluded patients treated endovascularly, patients with parenchymal hemorrhage without concomitant rPH and stroke mimics. We compared the variables from patients with deep or lobar rPH with those with no intracranial hemorrhage.We studied 934 patients (mean age 73.9±12.6 years and 52.8% were men. We observed rPH in 34 patients (3.6%; 9 (0.9% were deep and 25 (2.7% lobar. No hemorrhage was observed in 900 (96.6% patients. Deep rPH were associated with hypertensive episodes within first 24 hours after intravenous thrombolysis (77.7% vs 23.3%, p1 CMB (30.7% vs 4.4%, p = 0.003, lobar CMB (53.8% vs 3.0%, p<0.001 and severe leukoaraiosis (76.9% vs 42%, p = 0.02.A high blood pressure within the first 24 hours after intravenous thrombolysis is associated with deep rPH, whereas lobar rPH are associated with imaging markers of amyloid deposition. Thus, our results suggest that deep and lobar rPH after intravenous thrombolysis may have different mechanisms.

McFarland, K; Ettenberg, A

1995-12-01

The role of drug-paired environmental stimuli in opiate self-administration was investigated by exposing animals to discrete cues that were predictive of the availability or unavailability of heroin reinforcement. Rats were trained to traverse a straight arm runway for a reinforcement consisting of a single 0.1 mg/kg intravenous infusion of heroin delivered upon entrance to the goal box. On each trial, one of two discriminative olfactory stimuli (orange and almond) was used: one which signaled the availability of heroin in the goal box (S+), and one which signaled its absence (S-). The effect of dopamine (DA) receptor antagonism on reinforcement and motivational processes was investigated by pretreating subjects with 0.0, 0.15 or 0.30 mg/kg of the DA receptor antagonist drug, haloperidol. Haloperidol had no effect on operant runway performance (i.e. goal time) in any condition. However, 24 h later, on the first post-treatment trial, those haloperidol animals that received heroin in the goal box on the previous trial (i.e. the S+ condition) ran reliably more slowly than subjects that received vehicle on the previous S+ trial. These results suggest that haloperidol does not affect the motivational properties of stimuli which predict the availability of heroin, while it does diminish the reinforcing effects of actually receiving heroin.

Full Text Available A case of acute respiratory distress and hypoxemia following accidental intravenous injection of an oil-steroid solution in a body builder is presented. Chest roentography at the time of presentation showed diffuse bilateral opacities, and computed tomography revealed predominantly peripheral ground-glass opacifications. The patient’s symptoms gradually improved over 48 h and imaging of the chest was unremarkable one week later. The pathophysiology, diagnosis and treatment of this rare but potentially life-threatening complication of intravenous oil injection are discussed.

Contrast agent choice for intravenous coronary angiography

International Nuclear Information System (INIS)

Zeman, H.D.; Siddons, D.P.

1990-01-01

The screening of the general population for coronary artery disease would be practical if a method existed for visualizing the extent of occlusion after an intravenous injection of contrast agent. Measurements performed with monochromatic synchrotron radiation X-rays and an iodine-containing contrast agent at the Stanford Synchrotron Radiation Laboratory have shown that such an intravenous angiography procedure would be possible with an adequately intense monochromatic X-ray source. Because of the size and cost of synchrotron radiation facilities it would be desirable to make the most efficient use of the intensity available, while reducing as much as possible the radiation dose experienced by the patient. By choosing contrast agents containing elements with a higher atomic number than iodine, it is possible to both improve the image quality and reduce the patient radiation dose, while using the same synchrotron radiation source. By using Si monochromator crystals with a small mosaic spread, it is possible to increase the X-ray flux available for imaging by over an order of magnitude, without any changes in the storage ring or wiggler magnet. The most critical imaging task for intravenous coronary angiography utilizing synchrotron radiation X-rays is visualizing a coronary artery through the left ventricle or aorta which also contain contrast agent. Calculations have been made of the signal to noise ratio expected for this imaging task for various contrast agents with atomic numbers between that of iodine and bismuth. The X-ray energy spectrum of the X-17 superconduction wiggler beam line at the National Synchrotron Light Source at Brookhaven National Laboratory has been used for these calculations. Both perfect Si crystals and Si crystals with a small mosaic spread are considered as monochromators. Contrast agents containing Gd or Yb seem to have about the optimal calculated signal to noise ratio. (orig./HSI)

Intravenous lignocaine infusion for intractable pain in Ewing's sarcoma

Nivedita Page

2018-01-01

Full Text Available A 23-year-old female presented to our palliative care center with Ewing's sarcoma of the humerus with lung metastases. Pain in her arm was unrelieved by nonsteroidal anti-inflammatory drugs, neuropathic medication as well as morphine. She could not tolerate any further increase in opioid dose but was so distraught due to the pain that she wanted to die. An intravenous lignocaine infusion in a dose of 2 mg/kg was given over an hour for three successive days. This successfully relieved her pain after which she was settled with her original medication. We feel that in palliative care settings, where intractable pain and tolerance to morphine are so common, intravenous lignocaine infusions could provide a safe and effective tool for pain relief.

The prevalence of intravenous (IV) catheter-related infections is 0.5 per 1000 device days, and these infections cause tenderness, erythema, swelling and phlebitis. Catheter-related bloodstream infections (CRBSI) may independently increase hospital costs and length of stay; the aim of the study was to set up a standard operating procedure (SOP) for the maintenance of peripheral vein catheter patency and the prevention of IV catheter-related complications. This is a retrospective study, enrolling patients who received anesthesia between April 2010 and January 2011. The study included 1 month of pretest phase, and 3 months each of "notification" phase, "observation" phase and "end" phase, respectively. The cannulations were set up by surgical ward nurses following the SOP on establishing peripheral intravenous catheter in our hospital. The cannulation sites were then examined before surgery and postoperatively by registered nurse anesthetists using the Baxter Scale. We also tried to set up a feedback circuit to let ward nurses know about the IV patency rate. As a result, 14,682 patients were enrolled in the study. The incidence of IV therapy-related adverse events was 0.78% in the notification phase, 0.43% in the observation phase, and 0.13% in the end phase. Overall IV therapy-related events declined significantly (p phlebitis was associated with age (p phlebitis and improve quality. The checklist increases ward nurses' and nurse anesthetists' awareness of IV patency, and the feedback circuit substantially reduces IV event rate. Copyright © 2015. Published by Elsevier Taiwan.

A tomographic approach to intravenous coronary arteriography

Ritman, E.L.; Bove, A.A.

1986-01-01

Coronary artery anatomy can be visualized using high speed, volume scanning X-ray CT. A single scan during a bolus injection of contrast medium provides image data for display of all angles of view of the opacified coronary arterial tree. Due to the tomographic nature of volume image data the superposition of contrast filled cardiac chambers, such as would occur in the levophase of an intravenous injection of contrast agent, can be eliminated. Data are presented which support these statements. The Dynamic Spatial Reconstructor (DSR) was used to scan a life-like radiologic phantom of an adult human thorax in which the left atrial and ventricular chambers and the major epicardial coronary arteries were opacified so as to simulate the levophase of an intravenous injection of contrast agent. A catheter filled with diluted contrast agent and with regions of luminal narrowing (i.e. 'stenoses') was advanced along a tract equivalent to a right ventricular catheterization. Ease of visualization of the catheter 'stenoses' and the accuracy with which they can be measured are presented. (Auth.)

We studied a distinctive group of young intravenous Ritalin abusers with profound obstructive lung disease. Clinically, they seemed to have severe emphysema, but the pathologic basis of their symptoms had not been investigated previously. Seven patients have died and been autopsied: in four, the lungs were fixed, inflated, dried, and examined in detail radiologically, grossly, microscopically, and by electron probe X-ray microanalysis. All seven patients had severe panlobular (panacinar) emphysema that tended to be more severe in the lower lung zones and that was associated with microscopic talc granulomas. Vascular involvement by talc granulomas was variable, but significant interstitial fibrosis was not present. Five patients were tested for alpha-1-antitrypsin deficiency and found to be normal, as were six similar living patients. These findings indicate that some intravenous drug abusers develop emphysema that clinically, radiologically, and pathologically resembles that caused by alpha-1-antitrypsin deficiency but which must have a different pathogenesis. Talc from the Ritalin tablets may be important, but the mechanism remains to be elucidated

Glycemic variability is an independent predictor of mortality in critically ill patients. The objective of this study was to compare two intravenous insulin protocols in critically ill patients regarding the glycemic variability. This was a retrospective observational study performed by reviewing clinical records of patients from a Critical Care Unit for 4 consecutive months. First, a simpler Scale-Based Intravenous Insulin Protocol (SBIIP) was reviewed and later it was compared for the same months of the following year with a Sliding Scale-Based Intravenous Insulin Protocol (SSBIIP). All adult patients admitted to the unit during the referred months were included. Patients in whom the protocol was not adequately followed were excluded. A total of 557 patients were reviewed, of whom they had needed intravenous insulin 73 in the first group and 52 in the second group. Four and two patients were excluded in each group respectively. Glycemic variability for both day 1 (DS1) and total stay (DST) was lower in SSBIIP patients compared to SBIIP patients: SD1 34.88 vs 18.16 and SDT 36.45 vs 23.65 (P<.001). A glycemic management protocol in critically ill patients based on sliding scales decreases glycemic variability. Copyright © 2017 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

To verify the frequency of errors in the preparation and administration of intravenous medication in three Brazilian hospitals in the State of Bahia. The administration of intravenous medications constitutes a central activity in Brazilian nursing. Errors in performing this activity may result in irreparable damage to patients and may compromise the quality of care. Cross-sectional study, conducted in three hospitals in the State of Bahia, Brazil. Direct observation of the nursing staff (nurse technicians, auxiliary nurses and nurse attendants), preparing and administering intravenous medication. When preparing medication, wrong patient error did not occur in any of the three hospitals, whereas omission dose was the most frequent error in all study sites. When administering medication, the most frequent errors in the three hospitals were wrong dose and omission dose. The rates of error found are considered low compared with similar studies. The most frequent types of errors were wrong dose and omission dose. The hospitals studied showed different results with the smallest rates of errors occurring in hospital 1 that presented the best working conditions. Relevance to clinical practice. Studies such as this one have the potential to improve the quality of care.

Metallic mercury poisoning through intravenous injection is rare, especially for a homicide attempt. Diagnosis and treatment of the disease are challenging. A 34-year-old male presented with pyrexia, chill, fatigue, body aches, and pain of the dorsal aspect of right foot. Another case is that of a 29-year-old male who committed suicide by injecting himself metallic mercury 15 g intravenously and presented with dizzy, dyspnea, fatigue, sweatiness, and waist soreness. The patient's condition in case 1 was deteriorated after initial treatment. Imaging studies revealed multiple high-density spots throughout the body especially in the lungs. On further questioning, the patient's girlfriend acknowledged that she injected him about 40 g mercury intravenously 11 days ago. The diagnosis was then confirmed with a urinary mercury concentration of 4828 mg/L. Surgical excision, continuous blood purification, plasma exchange, alveolar lavage, and chelation were performed successively in case 1. Blood irrigation and chelation therapy were performed in case 2. The laboratory test results and organ function of the patient in case 1 gradually returned to normal. However, in case 2, the patient's dyspnea was getting worse and he finally died due to toxic encephalopathy and respiratory failure. Early diagnosis and appropriate treatment are critical for intravenous mercury poisoning. It should be concerned about the combined use of chelation agents and other treatments, such as surgical excision, hemodialysis and plasma exchange in clinical settings.

The use of intravenous golimumab (GLM-IV), in combination with methotrexate, was approved by the US Food and Drug Administration in July 2013 for the treatment of moderate to severe, active rheumatoid arthritis (RA). GLM-IV is available in 50-mg vials, and the prescribing information specifies a dosing regimen of 2 mg/kg at 0 and 4 weeks and then every 8 weeks thereafter. The purpose of this study was to examine the patterns of prescribing and administration of GLM-IV, including the demographic, clinical, and utilization characteristics of patients with RA newly treated with GLM-IV. Rheumatology practices across the continental United States were solicited for a chart-review study. Inclusion criteria were: (1) diagnosis of RA; (2) current treatment with GLM-IV; (3) age ≥18 years; and (4) lack of pregnancy (in female patients). Physicians were offered a monetary incentive for each eligible chart provided. An electronic case-report form was developed to aid in the chart data extraction and included fields for demographic characteristics, available comorbid diagnoses, prior RA treatments, and doses and dates of GLM-IV administration. A total of 117 eligible patient charts from 15 rheumatologist practices were reviewed. The patient sample was predominantly female (81.2%), with a mean (SD) age of 55.4 (14.5) years. A total of 55.6% of patients had evidence of biologic treatment before receiving GLM-IV, and 53% had at least 1 comorbid condition. In total, 300 individual GLM-IV infusions from this sample were reviewed. Due to the relatively recent approval of GLM-IV use by the US Food and Drug Administration, the majority of patients in this sample (69.2%) had received only between 2 and 4 infusions at the time of the review. For infusion records with valid dose data, the mean number of administered vials was 3.6 (0.8) (total dose, 180 mg); the majority of patients received a dose consistent with the prescribed dose of 2 mg/kg. Combination therapy with methotrexate was

In a randomized, parallel-group, single-center study in 42 healthy adults, the safety and pharmacokinetic parameters of an intravenous formulation of 18.75 and 37.5 mg diclofenac sodium (DFP-08) following single- and multiple-dose bolus administration were compared with diclofenac potassium 50 mg oral tablets. Mean AUC0-inf values for a 50-mg oral tablet and an 18.75-mg intravenous formulation were similar (1308.9 [393.0]) vs 1232.4 [147.6]). As measured by the AUC, DFP-08 18.75 mg and 37.5 mg demonstrated dose proportionality for extent of exposure. One subject in each of the placebo and DFP-08 18.75-mg groups and 2 subjects in the DFP-08 37.5-mg group reported adverse events that were considered by the investigator to be related to the study drug. All were mild in intensity and did not require treatment. Two subjects in the placebo group and 1 subject in the DFP-08 18.75-mg group reported grade 1 thrombophlebitis; no subjects reported higher than grade 1 thrombophlebitis after receiving a single intravenous dose. The 18.75- and 37.5-mg doses of intravenous diclofenac (single and multiple) were well tolerated for 7 days. Additional efficacy and safety studies are required to fully characterize the product. © 2015, The American College of Clinical Pharmacology.

Peripheral venous access in elderly, hospitalized patients is often challenging. The usual alternative is insertion of a central venous catheter, with associated risk for complications. The purpose of this investigation was to determine the relative incidence of phlebitis secondary to lower as compared to upper extremity intravenous catheters (IVCs) and associated risk factors. A non-randomized, observational, cohort-controlled study was carried out. Consecutive patients receiving a lower extremity IVC were enrolled and compared with patients receiving an upper extremity IVC. Patients were followed from insertion until removal of the IVC. The major endpoint was phlebitis. The incidence of phlebitis secondary to upper extremity IVCs was 3/50 (6 %) compared to 5/53 (9.4 %) in lower extremity IVCs (χ(2) Yates = 0.08, p = 0.776). Age, gender, obesity, diabetes mellitus, site (arm versus leg, left versus right), and size of needle were not found to be risk factors for phlebitis according to univariate analysis. None of the patients developed bloodstream infection. In elderly patients with poor venous access, lower extremity IVCs are a reasonable and low-risk alternative to central venous catheters.

Full Text Available Objectives: Peri-operative aspiration of gastric contents is a problem that causes certain respiratory problems including ARDS. Prophylaxis against aspiration of gastric contents is performed routinely in elective surgeries, but there is rare evidence on the efficacy of this method in emergency cesarean section. Materials and Methods: This is a randomized, controlled, double-blinded clinical trial. 60 parturients undergoing emergency cesarean section were randomly assigned into three groups of 20 each. They were allocated into two study and one placebo groups. The study group one and two received intravenous ranitidine (IV 50 mg or IV pantoprazole 40 mg, half an hour before induction of GA, respectively. The placebo group was administered just 5 ml of isotonic saline half an hour before GA induction. After intubation and confirmation of endotracheal tube insertion, the gastric contents were aspirated through a nasogastric tube for evaluation of acidity and volume. Results: A statistical difference between group one and two with the control group was observed in the acidity of gastric contents, but there was no difference in volume. Also, the PH level of gastric contents in patients receiving pantoprazole was significantly higher than the isotonic saline (p

Almost equivalent, intravenous iodine doses of the three new low-osmolar contrast media, ioxaglate (Hexabrix), iopamidol (Niopam) and iohexol (Omnipaque) have been compared for image quality on the intravenous urogram. Generally good radiographic images were obtained. Iohexol gave better results for the nephrogram and pelvicalyceal distension compared with the other contrast media, but only the nephrogram results were statistically significant. Pyelographic density and ureteric distension and density were similar with all three contrast media. In patients where low-osmolality contrast media need to be used for intravenous urography, we suggest that iohexol gives the best radiographic images. Other factors, such as cost and the relative incidence of side-effects of the low-osmolar contrast media also need to be taken into consideration. (author)

Advanced pancreatic cancer has a poor prognosis, and the current standard of care (gemcitabine based chemotherapy) provides a small survival advantage. However the drawback is the accompanying systemic toxicity, which targeted treatments may overcome. This study aimed to evaluate the safety and tolerability of KAb201, an anti-carcinoembryonic antigen monoclonal antibody, labelled with I 131 in pancreatic cancer (ISRCTN 16857581). Patients with histological/cytological proven inoperable adenocarcinoma of the head of pancreas were randomised to receive KAb 201 via either the intra-arterial or intravenous delivery route. The dose limiting toxicities within each group were determined. Patients were assessed for safety and efficacy and followed up until death. Between February 2003 and July 2005, 25 patients were enrolled. Nineteen patients were randomised, 9 to the intravenous and 10 to the intra-arterial arms. In the intra-arterial arm, dose limiting toxicity was seen in 2/6 (33%) patients at 50 mCi whereas in the intravenous arm, dose limiting toxicity was noted in 1/6 patients at 50 mCi, but did not occur at 75 mCi (0/3). The overall response rate was 6% (1/18). Median overall survival was 5.2 months (95% confidence interval = 3.3 to 9 months), with no significant difference between the intravenous and intra-arterial arms (log rank test p = 0.79). One patient was still alive at the time of this analysis. Dose limiting toxicity for KAb201 with I 131 by the intra-arterial route was 50 mCi, while dose limiting toxicity was not reached in the intravenous arm

Inadvertent perioperative hypothermia (a drop in core temperature to below 36°C) occurs because of interference with normal temperature regulation by anaesthetic drugs, exposure of skin for prolonged periods and receipt of large volumes of intravenous and irrigation fluids. If the temperature of these fluids is below core body temperature, they can cause significant heat loss. Warming intravenous and irrigation fluids to core body temperature or above might prevent some of this heat loss and subsequent hypothermia. To estimate the effectiveness of preoperative or intraoperative warming, or both, of intravenous and irrigation fluids in preventing perioperative hypothermia and its complications during surgery in adults. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 2), MEDLINE Ovid SP (1956 to 4 February 2014), EMBASE Ovid SP (1982 to 4 February 2014), the Institute for Scientific Information (ISI) Web of Science (1950 to 4 February 2014), Cumulative Index to Nursing and Allied Health Literature (CINAHL) EBSCOhost (1980 to 4 February 2014) and reference lists of identified articles. We also searched the Current Controlled Trials website and ClinicalTrials.gov. We included randomized controlled trials or quasi-randomized controlled trials comparing fluid warming methods versus standard care or versus other warming methods used to maintain normothermia. Two review authors independently extracted data from eligible trials and settled disputes with a third review author. We contacted study authors to ask for additional details when needed. We collected data on adverse events only if they were reported in the trials. We included in this review 24 studies with a total of 1250 participants. The trials included various numbers and types of participants. Investigators used a range of methods to warm fluids to temperatures between 37°C and 41°C. We found that evidence was of moderate quality because descriptions of trial design were

The effects of intravenous thrombolysis on floating thrombi in cervical and intracranial arteries of acute ischemic stroke patients are unknown. Similarly, the best prevention methods of early recurrences remain controversial. This study aimed to describe the clinical and radiological outcome of thrombolyzed strokes with floating thrombi. We retrospectively analyzed all thrombolyzed stroke patients in our institution between 2003 and 2010 with floating thrombi on acute CT-angiography before the intravenous thrombolysis. The floating thrombus was diagnosed if an elongated thrombus of at least 5 mm length, completely surrounded by contrast on supra-aortic neck or intracerebral arteries, was present on CT-angiography. Demographics, vascular risk factors, and comorbidities were recorded and stroke etiology was determined after a standardized workup. Repeat arterial imaging was performed by CTA at 24 h or before if clinical worsening was noted and then by Doppler and MRA during the first week and at four months. Of 409 thrombolyzed stroke patients undergoing acute CT Angiography, seven (1.7%) had a floating thrombus; of these seven, six had it in the anterior circulation. Demographics, risk factors and stroke severity of these patients were comparable to the other thrombolyzed patients. After intravenous thrombolysis, the floating thrombi resolved completely at 24 h in four of the patients, whereas one had an early recurrent stroke and one developed progressive worsening. One patient developed early occlusion of the carotid artery with floating thrombus and subsequently a TIA. The two patients with a stable floating thrombus had no clinical recurrences. In the literature, only one of four reported cases were found to have a thrombolysis-related early recurrence. Long-term outcome seemed similar in thrombolyzed patients with floating thrombus, despite a possible increase of very early recurrence. It remains to be established whether acute mechanical thrombectomy could be

Radiation absorbed doses due to intravenous administration of fluorine-18-fluorodeoxyglucose in positron emission tomography (PET) studies were estimated in normal volunteers. The time-activity curves were obtained for seven human organs (brain, heart, kidney, liver, lung, pancreas, and spleen) by using dynamic PET scans and for bladder content by using a single detector. These time-activity curves were used for the calculation of the cumulative activity in these organs. Absorbed doses were calculated by the MIRD method using the absorbed dose per unit of cumulated activity, 'S' value, transformed for the Japanese physique and the organ masses of the Japanese reference man. The bladder wall and the heart were the organs receiving higher doses of 1.2 x 10(-1) and 4.5 x 10(-2) mGy/MBq, respectively. The brain received a dose of 2.9 x 10(-2) mGy/MBq, and other organs received doses between 1.0 x 10(-2) and 3.0 x 10(-2) mGy/MBq. The effective dose equivalent was estimated to be 2.4 x 10(-2) mSv/MBq. These results were comparable to values of absorbed doses reported by other authors on the radiation dosimetry of this radiopharmaceutical

2017-12-01

Plasma administration has been recommended in calves older than 48h with failure of passive immunity (FPI) to provide immunity consistent with adequate colostral ingestion. However, the protective serum immunoglobulin G (IgG) concentrations (≥1000mg/dL) of plasma derived IgG only lasts up to 12h. In addition to IgG, maternally derived colostral cells also confer immunity. The objective of the study was to determine the effect of intravenous plasma transfusion on granulocyte and monocyte oxidative and phagocytic activity in calves with FPI. Twenty-seven, one day-old, Jersey calves were assigned into 3 groups. The colostral (CL, N=9) group received 3L of colostrum once by oroesophageal tubing. Two other groups of calves received 1L of colostrum once by oroesophageal tubing and were assigned based on their health status (sick or non-sick) at 4days of age, as the sick-group (SG, N=7) or the non-sick (NG, N=11) groups. At 4days of age, the SG and NG groups were administered plasma intravenously at 30mL/kg. Granulocyte and monocyte oxidative and phagocytic activity was determined by flow cytometry. There was no significant difference in the granulocyte and monocyte oxidative or phagocytic activity among the 3 groups (P>0.05). Plasma administration had no significant effect on the oxidative or phagocytic activity of granulocytes or monocytes. In clinical practice, plasma administration for enhancing oxidative or phagocytic activity of granulocytes or monocytes, alone, might not be justified in calves with FPI.

Objective: The purpose of this study was to evaluate the diagnostic performance of intravenous contrast enhanced computed tomographic colonoscopy (IVCTC) in the diagnosis of clinically suspected colorectal polyps in children, using conventional colonoscopy (CC) as the gold standard. Methods: This was a prospective study conducted between July 2008 and June 2010. 30 pediatric patients with history of rectal bleeding and clinically suspected to have colorectal polyps were enrolled. All of the patients underwent IVCTC followed by CC. 30 IVCTC and 31 CC were performed in 30 patients. The findings of IVCTC were compared with those of CC. Statistical analysis was performed to obtain diagnostic performance values of IVCTC on per polyp (sensitivity and positive predictive value) and per patient (sensitivity, specificity, positive predictive value and negative predictive value) basis. Results: By IVCTC, 63 polyps were detected in 28 patients of which 53 polyps were eligible for inclusion in the statistical analysis. 60 polyps were detected by CC in 28 patients of which 50 polyps were eligible for inclusion in the statistical analysis. The per polyp sensitivity and positive predictive values were 94% and 88.6% respectively. The per patient sensitivity, specificity, positive predictive value, and negative predictive values were 96.4, 50, 96.4, and 50% respectively. Twenty polyps, in 10 patients, were visualized only after intravenous contrast administration of which 5 polyps, in 5 patients, were likely to have been missed in the absence of the intravenous contrast injection as these polyps were submerged in fluid. Four patients would have had a false negative CTC examination if the intravenous contrast had not been injected; while in another patient, the number of polyps would have been underestimated. Conclusion: CTC is capable of serving as a safe and efficient non-invasive tool for evaluating children with clinically suspected colorectal polyps. Administration of

The pain associated with spinal puncture is severe, and the memory of this uncomfortable procedure often deters patients from undergoing the procedure again. Therefore, it is important to make the patient as comfortable as possible when this procedure is performed. We administrated a low-dose (1-2.5 mg) of midazolam intravenously several minutes before conducting a spinal-tap in 200 patients undergoing elective surgery of the lower limb. The dose of midazolam used was based on the patient's age and weight, and we investigated remaining of a memory concerning the spinal-tap procedure and side effects of midazolam at the end of surgery. Memory of the spinal-tap procedure remained in 14.0%, 1.9%, and 32.7% of the patients who had received benzodiazepine preoperatively and in 25.0%, 40.0%, and 60.9% of the patients who hadn't received benzodiazepine preoperatively in the age group or =70 years, respectively. No patient experienced severe respiratory depression, but an excessive sedation or restlessness was experienced in 1.6%, 4.8%, and 5.2% of the patients. In the patients aged memory concerning the spinal-tap procedure; however, it is important to note that the number of side effects associated with this procedure increases in patients aged > or =60 years.

Hepatic veno-occlusive disease (VOD) is a common complication of haematopoietic stem cell transplantation (HSCT), with reported incidences of 5-40% in children. Recently, defibrotide (DF) has been successfully used as prophylaxis and treatment of VOD. This study reports data on 63 human leucocyte antigen-matched HSCT performed in 57 children affected by beta thalassemia at very high risk for developing VOD (liver fibrosis, iron overload, hepatitis C virus infections, busulphan-based conditioning, methotraexate + ciclosporine). All patients received a busulphan-based conditioning regimen, either orally (four HSCT) or intravenously (59 HSCT). All patients received oral DF (40 mg/kg per day, final dose) as VOD prophylaxis from median day -9 to median day +29. In order to overcome the lack of oral paediatric formulations, a galenic formulation was administered. DF was well tolerated. Only one patient fulfilled Seattle Criteria for VOD diagnosis. This patient had discontinued DF 6 d prior to VOD onset, due to high risk of haemorrhage. We concluded that oral defibrotide prophylaxis and i.v. busulphan safely abated VOD incidence in high-risk patients who had undergone HSCT. A galenic preparation of oral DF also permits this treatment in low-weight patients. Costs of DF prophylaxis are acceptable considering the reduced incidence of VOD.

Chloroform, a halogenated hydrocarbon, causes central nervous system depression, cardiac arrhythmias, and hepatotoxicity. We describe a case of chloroform ingestion with a confirmatory serum level and resultant hepatotoxicity successfully treated with intravenously administered N-acetylcysteine (NAC). A 19-year-old man attempting suicide ingested approximately 75 mL of chloroform. He was unresponsive and intubated upon arrival. Intravenously administered NAC was started after initial stabilization was complete. His vital signs were normal. Admission laboratory values revealed normal serum electrolytes, AST, ALT, PT, BUN, creatinine, and bilirubin. Serum ethanol level was 15 mg/dL, and aspirin and acetaminophen were undetectable. The patient was extubated but developed liver function abnormalities with a peak AST of 224 IU/L, ALT of 583 IU/L, and bilirubin level reaching 16.3 mg/dL. NAC was continued through hospital day 6. Serum chloroform level obtained on admission was 91 μg/mL. The patient was discharged to psychiatry without known sequelae and normal liver function tests. The average serum chloroform level in fatal cases of inhalational chloroform poisoning was 64 μg/mL, significantly lower than our patient. The toxicity is believed to be similar in both inhalation and ingestion routes of exposure, with mortality predominantly resulting from anoxia secondary to central nervous system depression. Hepatocellular toxicity is thought to result from free radical-induced oxidative damage. Previous reports describe survival after treatment with orally administered NAC, we report the first use of intravenously administered NAC for chloroform ingestion. Acute oral ingestion of chloroform is extremely rare. Our case illustrates that with appropriate supportive care, patients can recover from chloroform ingestion, and intravenously administered NAC may be of benefit in such cases.

107 patients with thoracal or mediastinal growths underwent computerized tomography of the thorax both in normal condition and after receiving intravenous applications of non-ionic X-ray contrast media. The additional information obtained by use of contrast media was established in relation to the histological findings. The method led to enhanced demarcation of the tumor of the mediastinum or hilus in 40% of the patients. Tumor perfusion was helpful in 20% of the cases for differential diagnosis. Vessel infiltrations or abnormal conditions were found in about 30% of patients. 24% of the tests yielded no additional information. Analysing CT as compared to the histological examination of lymph nodes proved CT under normal conditions to be a sensitive method in 29% of cases if the hilus was the site of the tumor; contrast media raised this sensitivity to 43%. In the mediastinal area, sensitivity was 44% without and 56% with contrast media. (orig.) [de

Migraine is a leading headache etiology that frequently presents to the emergency department (ED). In the present study, we aimed to determine the efficacy of dexketoprofen in aborting migraine headaches in the ED. This prospective, randomized, double-blind study was conducted in an ED of a tertiary care hospital using allocation concealment. Patients were allocated into two arms to receive the study drug; 50 mg dexketoprofen in 50 ml saline and 50 ml saline as placebo. Change in pain intensity was measured by the visual analog scale at baseline, both at 30 and 45 minutes after the study medication was administered. Rescue medication requirement and pain relapse were also recorded by a telephone follow-up at 48 hours. A total of 224 patients (112 in each group) were included into the final analysis. Mean age of the study participants was 37 ± 11 (SD) and 25% (n = 56) of them were male. The median pain improvement at 45 minutes for patients receiving dexketoprofen was 55 (IQR: 49 to 60) and 30 (IQR: 25 to 35) for those receiving placebo. The mean difference between the two groups at 45 minutes was 21.4 (95% CI: 14.4. to 28.5). Rescue drugs were needed in 22.3% of patients who received dexketoprofen compared to 55.4% in patients who received placebo (dif: 33.1%; 95% CI: 20% to 45%). There were no adverse events reported in either group during the study period. Intravenous dexketoprofen is superior to placebo in relieving migraine headaches in the ED. It may be a suitable therapy with minimum side effects in patients presenting with a migraine headache to the ED. © International Headache Society 2015.

A previously healthy 2 1/2-year-old girl developed status epilepticus followed by cortical blindness during intravenous N-acetylcysteine therapy for paracetamol ingestion. The child's vision was almost completely recovered during the 18 months follow-up period. We assume that the cortical blindness was a postictal sequela after prolonged seizure episode, most probably due to respiratory depression induced by N-acetylcysteine.

Full Text Available Background: Ventilator-associated pneumonia (VAP is a common side effect in patients who receive intravenous sedation infusion. In routine care, after starting sedation infusion for patients who receive mechanical ventilation, interruption of sedation starts without protocol. This study aimed to evaluate the effect of daily sedation vacation protocol on the incidence of VAP in mechanically ventilated patients. Materials and Methods: In this clinical trial study, 80 patients with intravenous sedation infusion were selected and randomly allocated to intervention and control groups. In the intervention group, daily sedation vacation protocol and in the control group, routine sedation vacation was followed. Modified clinical pulmonary infection score questionnaire was completed before intervention and on the third, fourth, and fifth days after intervention. Data were analyzed by using repeated measures analysis of variance (ANOVA, Chi-square, and independent t-test. Results: The results of this study showed that the incidence rate of VAP in the intervention and control groups was 0% versus 15% on the third day of intervention, 12.5% versus 50% on the fourth day, and 27.5% versus 55.3% on the fifth day of intervention in the intervention and control groups, respectively. The incidence of VAP in the intervention group was significantly lower than in the control group (P < 0.05. Conclusions: The results of this study showed that in patients with intravenous sedation, infusion of a daily sedation vacation protocol may reduce the incidence of VAP. Therefore, in order to prevent VAP, nurses are recommended to use this daily sedation vacation protocol.

Full Text Available Radium-223 (223Ra dichloride is an approved intravenous radiotherapy for patients with osseous metastases from castration-resistant prostate cancer (CRPC. In addition to the therapeutic alpha radiation, there is additional 223Ra radiation generated which produces photons that can be imaged with conventional gamma cameras. No studies have evaluated real-time and quality imaging during intravenous 223Ra administration to verify systemic circulation and exclude 223Ra extravasation at the injection site. A retrospective review was performed for fifteen 223Ra administrations for CRPC patients which were imaged using a large field of view portable gamma camera (LFOVPGC for the purposes of quality control and patient safety. Dynamic imaging of the chest was performed before, during, and after the 223Ra administration to verify systemic circulation, per institutional clinical protocol. Before and after 223Ra administration, a static image was obtained of the intravenous access site. Dynamic imaging of the chest confirmed systemic administration early during the 1-minute injection period for all patients. There were no cases of focal 223Ra extravasation at the site of intravenous access. These results verify that systemic 223Ra administrations can be quantified with real-time imaging using an LFOVPGC. This simple approach can confirm and quantify systemic circulation of 223Ra early during injection and exclude focal extravasation for the purposes of quality control.

We studied effects of OK-432 on the bone marrow and peripheral blood cells of lung cancer patients. The nuclear cell count of bone marrow increased in 5 to 7 patients upon intravenous treatment with OK-432 compared with 3 of 6 patients who were intramuscularly treated with OK-432. Serial neutrophil counts of bone marrow increased in all 7 patients treated intravenously compared with 3 of 6 patients treated intramuscularly. The mean nuclear cell count or the serial neutrophil count of bone marrow in intravenously treated patients was significantly higher than the pretreatment values (p less than 0.001). In the peripheral blood picture, the difference in white blood cells or neutrophils before and after intravenous treatment was also statistically significant (p less than 0.01). There was no change in the erythrocytic series count of bone marrow and the hemoglobin count. Our results support the superiority of intravenous OK-432 treatment over intramuscular treatment in the growth-accelerating effect on bone marrow cells, especially regarding the neutrophil series.

In patients who received thrombolytic therapy for acute myocardial infarction (AMI), we observed 3 distinct patterns in gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA)-enhanced magnetic resonance (MR) imaging. To clarify the significance of these distribution patterns of Gd-DTPA, 20 consecutive patients underwent Gd-DTPA-enhanced MR imaging 7-10 days after AMI. All of the patients received intravenous recombinant tissue plasminogen activator (IVTPA) within 6 h of onset. Echocardiograms were obtained prior to and serially over 10 days, and interpreted for regional wall motion. Coronary angiograms were obtained the day before discharge. None of the 6 patients with a closed infarct-related artery, and 9 of the 14 patients with an open artery, demonstrated subendocardial enhancement (p<0.05). All of these latter 9 patients demonstrated a significant improvement in wall motion between days 1 and 10 after AMI. In contrast, only 1 of the 7 patients with transmural enhancement and none of the 4 patients with non-homogeneous enhancement demonstrated improvement of wall motion on day 10 (p<0.05). We concluded that subendocardial enhancement was a fair prognostic sign for restoration of regional cardiac function in patients who received IVTPA during AMI. (author)

A study of some parameters affecting the time activity histogram of an intravenous bolus injection of radioactivity was performed. A scoring system for bolus compactness was attempted. A score of 2 and above was considered to be a satisfactory bolus. Volumes less than 1 ml tended to result in a satisfactory bolus. The nature of radiopharmaceutical injected, different injecters and age of the patient did not affect the score. Thyrotoxic patients gave the best bolus score. (orig.) [de

Deep vein thrombosis of the lower limbs in intravenous drug users

2015-04-01

Full Text Available Addiction to intravenously administered drugs has been a serious epidemiological problem for years. Among the related health complications, deep vein thrombosis (DVT is one of the most important. This paper provides an illustrative presentation of DVT in intravenous drug users (IDUs, HIV-positive subjects among them.We searched PubMed, Ovid Journals, Scopus, ScienceDirect, Cochrane Library, Google Scholar and references from articles obtained. The main terms used to identify appropriate studies of DVT in IDUs were ‘intravenous drug users’, ‘substance-related disorders’ and ‘deep vein thrombosis’.No guidelines exist for DVT in intravenous drug users. As many as 47.6% of IDUs report having suffered from DVT. IDUs may constitute approx. 50% of patients under 40 years of age with DVT, this being promoted by multiple vein punctures, groin injections, lack of sterility, insoluble microparticles and other factors. The clinical appearance is more complex than in the general population, which also makes prognosis more difficult. HIV infection can worsen DVT. It often appears as proximal iliofemoral thrombosis, accompanied by local and general complications. Ultrasound with a compression test is an objective method of choice, but must often be complemented with computed tomography. Antithrombotic therapy in IDUs needs to be applied individually. The optimal method is supervised therapy at addiction treatment services.Individual and public preventive measures, among them locally prepared guidelines for DVT in IDUs, may be the most important processes capable of effectively reducing the morbidity of septic and non-septic DVT.

Materials and Methods: Patients were randomly divided into three groups: Group 1 (gabapentin, n = 46 received 400 mg gabapentin, Group 2 (dexamethasone, n = 46 received 8 mg dexamethasone and Group 3 (gabapentin plus dexamethasone, n = 46 received both 400 mg gabapentin and 8 mg dexamethasone I.V. 1 h before the start of surgery. Standard induction and maintenance of anesthesia were accomplished. Visual analog scale for pain was recorded for 12 h. Side effects were noted. Results: Hemodynamics at various time interval (0, 5, 10, 15, 20, 25 and 30 min of laryngeal mask airway insertion and PONV were found significantly lower in Group 3 than in Group 1 and Group 2 (P 3 was significantly longer in Group 3 (510.00 ± 61.64 min than in Group 1 (352.83 ± 80.61 min and in Group 2 (294.78 ± 60.76 min, (P < 0.05. Conclusion: The present study concludes that the combination of oral Gabapentin and I.V. dexamethasone has significantly less hemodynamic changes, better postoperative analgesia and less incidence of PONV than individual administration of each drug.

The radiation dosimetric literature concerning the medical and non-medical personnel working in nuclear medicine departments are limited, particularly radiation doses received by radiation worker in nuclear medicine department during positron emission tomography (PET) radiopharmaceutical injection process. This is of interest and concern for the personnel. To measure the radiation dose received by the staff involved in injection process of Fluorine-18 Fluorodeoxyglucose (FDG). The effective whole body doses to the radiation workers involved in injections of 1511 patients over a period of 10 weeks were evaluated using pocket dosimeter. Each patient was injected with 5 MBq/kg of 18 F FDG. The 18 F-FDG injection protocol followed in our department is as follows. The technologist dispenses the dose to be injected and records the pre-injection activity. The nursing staff members then secure an intravenous catheter. The nuclear medicine physicians/residents inject the dose on a rotation basis in accordance with ALARA principle. After the injection of the tracer, the nursing staff members flush the intravenous catheter. The person who injected the tracer then measures the post-injection residual dose in the syringe. The mean effective whole body doses per injection for the staff were the following: Nurses received 1.44 ± 0.22 μSv/injection (3.71 ± 0.48 nSv/MBq), for doctors the dose values were 2.44 ± 0.25 μSv/injection (6.29 ± 0.49 nSv/MBq) and for technologists the doses were 0.61 ± 0.10 μSv/injection (1.58 ± 0.21 nSv/MBq). It was seen that the mean effective whole body dose per injection of our positron emission tomography/computed tomography (PET/CT) staff who were involved in the 18 F-FDG injection process was maximum for doctors (54.34% differential doses), followed by nurses (32.02% differential doses) and technologist (13.64% differential doses). This study confirms that low levels of radiation dose are received by staff during 18 F-FDG injection and

The pharmacokinetics of flomoxef in serum and in the mucosal tissue of the middle ear and mastoid were studied in 9 patients undergoing tympanoplasties. All patients received 1 g of flomoxef intravenously. Flomoxef levels in serum and in mucosal tissue were determined by a bioassay method. The peak value of mean concentrations of flomoxef in the mucosal tissue was 30.3 +/- 11.7 micrograms/ml at 10 min after the administrations. Pharmacokinetic analyses showed that the concentration of flomoxef in the mucosal tissue was over 1.56 micrograms/ml (which is the MIC90 for the common pathogens of otitis media) for more than 2 h and decreased parallel with serum concentration with a half-life of about 40 min.

Full Text Available Timely intravenous (IV thrombolysis for acute ischemic stroke is associated with better clinical outcomes. Acute stroke care implemented with "Stroke Code" (SC may increase IV tissue plasminogen activator (tPA administration. The present study aimed to investigate the impact of SC on thrombolysis.The study period was divided into the "pre-SC era" (January 2006 to July 2010 and "SC era" (August 2010 to July 2013. Demographics, critical times (stroke symptom onset, presentation to the emergency department, neuroimaging, thrombolysis, stroke severity, and clinical outcomes were recorded and compared between the two eras.During the study period, 5957 patients with acute ischemic stroke were admitted; of these, 1301 (21.8% arrived at the emergency department within 3 h of stroke onset and 307 (5.2% received IV-tPA. The number and frequency of IV-tPA treatments for patients with an onset-to-door time of <3 h increased from the pre-SC era (n = 91, 13.9% to the SC era (n = 216, 33.3% (P<0.001. SC also improved the efficiency of IV-tPA administration; the median door-to-needle time decreased (88 to 51 min, P<0.001 and the percentage of door-to-needle times ≤60 min increased (14.3% to 71.3%, P<0.001. The SC era group tended to have more patients with good outcome (modified Rankin Scale ≤2 at discharge (49.5 vs. 39.6%, P = 0.11, with no difference in symptomatic hemorrhage events or in-hospital mortality.The SC protocol increases the percentage of acute ischemic stroke patients receiving IV-tPA and decreases door-to-needle time.

Intravenous Immunoglobulin therapy for anti-E hemolytic disease in the newborn.

Anti-E alloimmunisation is a less common cause of haemolytic disease in the newborn (HDN) and is usually associated with mild to moderate clinical manifestations, that are often less severe than anti-D immunisation. Conventional treatments for HDN are phototherapy and exchange transfusion, the latter still representing a high-risk procedure. Currently, intravenous immunoglobulin has been used as alternative treatment for HDN to reduce the need for exchange transfusion, as well as the length of phototherapy and hospitalisation. We report a case of anti-E HDN treated successfully with intravenous immunoglobulin, as adjuvant treatment to phototherapy.

Because of the increased use of intravenous injection of contrast material for the evaluation of cardiac structure and function by digital subtraction techniques, a study was done to assess the hemodynamic effects of contrast material when used in this fashion in man. In 10 patients, with each serving as his own control, the effects of intravenous and intraventricular injections of sodium meglumine diatrizoate (Renografin 76) in the same dose were compared. There was no difference between these two methods with respect to changes in pulmonary wedge pressures, systemic pressures, and pulmonary vascular resistance. The elevation of mean pulmonary artery and right atrial pressure was greater after the intraventricular injection (p <0.05). The elevated cardiac output and systemic vascular resistance returned to control values somewhat more quickly after the intravenous injection (p<0.001 and p<0.05, respectively); and the increase in cardiac output was greater after the intravenous injection at 1 min (p<0.05), but less than after the intraventricular injection at 2 min (p<0.05). Despite the detection of these statistically significant differences, the magnitude and timing of these differences are too small to justify the notion that imaging by intravenous injections of standard ionic contrast media provides any substantial hemodynamic benefits or decreased risk to the patient

Status epilepticus and acute prolonged seizures are the most commonly occurring neurological emergencies in children. Such events have high morbidity and mortality rates along with poor long-term outcomes, depending on their duration and causes. Therefore, such seizures warrant urgent treatment using appropriate doses of anticonvulsants. Benzodiazepines, phenobarbital, and phenytoin are the most commonly used anticonvulsants for controlling status epilepticus and acute prolonged seizures. However, these medications have several well-known adverse effects. Previous studies on both adults and children have shown the efficacy and safety of rapid infusion of valproate in controlling status epilepticus. However, few well-designed randomised trials have been carried out in children, and there remains a paucity of data regarding intravenous sodium valproate use in children. Therefore, our aim was to compare the efficacy and safety of rapid loading of valproate with those of intravenous phenobarbital in children with status epilepticus and acute prolonged seizures. Sixty children (30 in each group) with convulsive status epilepticus and acute prolonged seizures were enrolled and randomly assigned to receive either valproate or phenobarbital. The main outcome variable was termination of all convulsive activity within 20 min of starting anticonvulsant infusion. Intravenous rapid loading of valproate was successful in seizure termination in (27/30, 90%) of patients compared to phenobarbital (23/30, 77%) (p = 0.189). Clinically significant adverse effects occurred in 74% patients of the phenobarbital group and 24% patients of the valproate group (p < 0.001). In conclusion, rapid loading of valproate is effective and safe in controlling convulsive status epilepticus and acute prolonged convulsive seizures in children. Intravenous valproate should be considered as a suitable choice for terminating status epilepticus and acute prolonged seizures in children. Copyright �

Full Text Available Introduction: Despite wide use of hyoscine by midwives and doctors as an adjunct to labor, the obstetrics literature contains few references to the effect of this drug. This study was a double blinded, randomized controlled trial of primigravidas in Iran to determine the effects of hyoscine intravenous injection on parturition (labor. Methods:One hundred primigravidas in uncomplicated spontaneous labor with cervical dilation less than 4 cm and cervical effacement < 50% were randomly assigned into two groups; the experimental group ( N = 50 receiving 20 mg hyoscine and the control group ( N = 50 receiving placebo, with predetermined codes injected at the beginning of the active phase of labor. The groups were compared for labor progress, fetal tachycardia and bradycardia after 0.5 and 1h of injection, Apgar score and birth weight. Statistical methods for normally distributed variables included 2- tailed student T test and chi- square analysis. The accepted level of significance was p < 0.05. Results:The two groups were similar in respect to maternal age, gestational age , initial cervical effacement & dilation and mean birth weight. The mean change in the cervical effacement and dilation after 1 & 2 h of injection was significantly higher in those receiving hyoscine (p< 0.0001. There was a significant difference in the duration of active phase and second stage of labor in the two groups ( p < 0.0001 . Fetal tachycardia and bradycardia occurred more frequently in patients in the hyoscine group as compared to the control group but the difference was not significant. The difference between the mean first and fifth- minute Apgar score was not significant, too. Conclusion: This small study suggests the benefits of a single dose of hyoscine for labor progress and represents the first attempt to evaluate this medication. However, larger randomized studies are needed to establish the efficacy, safety, and optimal dose of hyoscine .

Intravenously administered ethyl alcohol may be effective as analgesic and hypotensive peripheric vasoactive drug. In the Intensive Care Departments parenteral ethanol administration is infrequent because no "sure dosage" can be suggested in adults and children. Liver, kidney and C.N.S. diseases can worsen; foetopathy can follow. Drug-ethanol interaction may be particularly important for some patients admitted in Intensive Care Departments. Often the potential caloric support cannot be fully utilized ("empty" calories) and seldom hyperventilation, hyperlactacidemia and impaired protein synthesis can follow.

One Stage Radical Removal of Intravenous Leiomyomatosis Extending to the Right Atrium via the Bilateral Gonadal Veins

Directory of Open Access Journals (Sweden)

X. Gui

Full Text Available : Background: Intravenous leiomyomatosis is a benign and rare smooth muscle cell tumor. Extension to the right heart is exceptional. Among the reported cases, the tumor is usually known to enter through the lumen of the iliac vein and grows into the inferior vena cava; involvement of bilateral gonadal veins is rarely reported. Complete tumor resection is the key to therapy. Case presentation: A 25 year old female Chinese patient suffering from abdominal distention for 1 month, who was diagnosed with intravenous leiomyomatosis extending to the heart, from pre-operative imaging studies, is presented. A one stage procedure with complete excision of the tumor was performed. Histopathological findings confirmed the diagnosis of intravenous leiomyomatosis. The patient's post-operative recovery was uneventful, without recurrence and re-stenosis at 1 year follow up. Conclusion: Intravenous leiomyomatosis may grow within veins along various routes. This case demonstrated intravenous leiomyomatosis with tumor extension through bilateral gonadal veins extending to the heart. It is believed that one stage radical resection can be a practical and effective alternative for the patients in good clinical condition. Long-term follow up is recommended because of the possibility of recurrence and metastases.

Full Text Available The efficacy of intravenous immunoglobulins (IVIg in patients with autoimmune diseases (AID has been known for several decades. Majority of these patients received IVIg in hospital. A retrospective study was conducted in 22 centers in France to evaluate the feasibility of the administration of Tegeline, an IVIg from LFB Biomedicaments, and assess its safety at home, compared to in hospital, in patients with AID. The included patients were at least 18 years old, suffering from AID, and treated with at least 1 cycle of Tegeline at home after receiving 3 consecutive cycles of hospital-based treatment with Tegeline at a dose between 1 and 2 g/kg/cycle. Forty-six patients with AID, in most cases immune-mediated neuropathies, received a total of 138 cycles of Tegeline in hospital and then 323 at home. Forty-five drug-related adverse events occurred in 17 patients who received their cycles at home compared to 24 adverse events in hospital in 15 patients. Serious adverse events occurred in 3 patients during home treatment, but they were not life-threatening and did not lead to discontinuation of Tegeline. Forty-five patients continued their treatment with Tegeline at home or in hospital; 39 (84.8% were still receiving home treatment at the end of the study. In conclusion, the study demonstrates the good safety profile of Tegeline administered at home at high doses in patients with AID who are eligible for home administration of Tegeline.

Insulin adsorbs to plastic tubing, which decreases the concentration of an insulin solution delivered from an intravenous infusion set. Dwelling insulin within tubing before starting the infusion decreases adsorption but delays treatment initiation and wastes time in infusion preparation. The lack of data on dwell time effects results in wide variability in practice. We aim to determine the effect of dwell time on insulin concentration from intravenous infusion tubing. In this in vitro study, we used insulin solutions with concentrations of 0.1 unit/mL, 1 unit/mL, and 10 units/mL. Each solution dwelled in intravenous infusion sets for 0, 15, 30, or 60 min. After the dwell, we measured insulin concentrations from the solution bags and tubing. We repeated each insulin concentration-dwell time combination five times. Comparisons were performed using analyses of variance. For each of the three insulin concentrations, the mean insulin concentrations from the tubing were not significantly different between dwell times. Duration of dwell time did not affect insulin adsorption in polypropylene intravenous infusion sets. We recommend that following a 20-mL flush, insulin infusions can be started without any dwell time. Removal of dwell times may improve clinical practice by minimizing preparation time and will allow faster initiation of insulin infusion therapy.

The effective delivery of short interfering RNA (siRNA) to brain following intravenous administration requires the development of a delivery system for transport of the siRNA across the brain capillary endothelial wall, which forms the blood-brain barrier in vivo. siRNA was delivered to brain in vivo with the combined use of a receptor-specific monoclonal antibody delivery system, and avidin-biotin technology. The siRNA was mono-biotinylated on either terminus of the sense strand, in parallel with the production of a conjugate of the targeting MAb and streptavidin. Rat glial cells (C6 or RG-2) were permanently transfected with the luciferase gene, and implanted in the brain of adult rats. Following the formation of intra-cranial tumors, the rats were treated with a single intravenous injection of 270 microg/kg of biotinylated siRNA attached to a transferrin receptor antibody via a biotin-streptavidin linker. The intravenous administration of the siRNA caused a 69-81% decrease in luciferase gene expression in the intracranial brain cancer in vivo. Brain delivery of siRNA following intravenous administration is possible with siRNAs that are targeted to brain with the combined use of receptor specific antibody delivery systems and avidin-biotin technology.

We seek to determine whether an initial intravenous bolus of 5% dextrose in normal saline solution compared with normal saline solution will lead to a lower proportion of hospitalized patients and a greater reduction in serum ketone levels in children with gastroenteritis and dehydration. We enrolled children aged 6 months to 6 years in a double-blind, randomized controlled trial of patients presenting to a pediatric emergency department. Subjects were randomized to receive a 20 mL/kg infusion of either 5% dextrose in normal saline solution or normal saline solution. Serum ketone levels were measured before and at 1- and 2-hour intervals after the initial study fluid bolus administration. Primary outcome was the proportion of children hospitalized. Secondary outcome was change in serum ketone levels over time. One hundred eighty-eight children were enrolled. The proportion of children hospitalized did not differ between groups (35% in the 5% dextrose in normal saline solution group versus 44% in the normal saline solution group; risk difference 9%; 95% confidence interval [CI] -5% to 22%). Compared with children who received normal saline solution, those who received 5% dextrose in normal saline solution had a greater reduction in mean serum ketone levels at both 1 hour (mean Δ 1.2 versus 0.1 mmol/L; mean difference 1.1 mmol/L; 95% CI 0.4 to 1.9 mmol/L) and 2 hours (mean Δ 1.9 versus 0.3 mmol/L; mean difference 1.6 mmol/L; 95% CI 0.9 to 2.3 mmol/L). Administration of a dextrose-containing bolus compared with normal saline did not lead to a lower rate of hospitalization for children with gastroenteritis and dehydration. There was, however, a greater reduction in serum ketone levels in patients who received 5% dextrose in normal saline solution. Copyright © 2012. Published by Mosby, Inc.

Background and purpose: To evaluate the effect of an intravenous contrast agent (CA) on dose calculations and its clinical significance in intensity modulated radiation therapy (IMRT) plans for head and neck cancer. Materials and methods: Fifteen patients with head and neck cancer and involved neck nodes were enrolled. Each patient took two sets of computerized tomography (CT) in the same position before and after intravenous CA injections. Target volumes and organs at risk (OAR) were contoured on the enhanced CT, and then an IMRT plan of nine equiangular beams with a 6 MV X-ray was created. After the fusion of non-enhanced and enhanced CTs, the contours and the IMRT plan created from the enhanced CT were copied and placed to the non-enhanced CT. Doses were calculated again from the non-enhanced CT by the same IMRT plan. The radiation doses calculated from the two sets of CTs were compared with regard to planning target volumes (PTV) and the three OARs, both parotid glands and the spinal cord, by Wilcoxon's signed rank test. Results: The doses (maximum, mean, and the dose of 95% of PTV received (D 95% )) of PTV70 and PTV59.4 calculated from the enhanced CTs were lower than those from the non-enhanced CTs (p < 0.05), but the dose differences were less than 1% compared to the doses calculated from the enhanced CTs. The doses of PTV50.4, parotid glands, and spinal cord were not significantly different between the non-enhanced and enhanced CTs. Conclusions: The difference between the doses calculated from the CTs with and without CA enhancement was tolerably small, therefore using intravenous CA could be recommended for the planning CT of head and neck IMRT

Chronic renal failure is a type of clinical syndrome originating from chronic renal diseases. The aim of the study was to investigate the effect of astrogaloside on the inflammation and immunity of renal failure patients receiving maintenance dialysis. We randomly selected 92 renal failure patients receiving maintenance dialysis who were admitted to hospital for treatment between May, 2015 and April, 2016. Patients were randomly divided into the control (n=46) and observation (n=46) groups. Patients in the control group received the regular dialysis plus the basic treatment in Western medicine, while in the observation group, patients additionally received astrogaloside via intravenous injection as treatment. We compared the clinical efficacy of patients between the two groups, residual renal function (RRF), changes in urine volume, variations in inflammatory indicators [C-reaction protein (CRP), interleukin-6 (IL-6), IL-17, and tumor necrosis factor-α (TNF-α)] before and after treatment, and the levels of the thymus-dependent lymphocyte (T cells) subgroup (CD3 + , CD4 + , CD8 + and CD4 + /CD8 + ) in the immune system of patients after treatment. In the observation group, the total effective rate was significantly higher than that in the control group (Prenal failure patients receiving the maintenance dialysis, ameliorate the inflammatory responses, and enhance the immune function, thereby increasing the disease resistance of patients and improving the clinical symptoms.

Prophylaxis or therapy with a combination of a neurokinin 1 (NK-1) receptor antagonist (RA), a 5-hydroxytryptamine- 3 (5-HT3) RA, and dexamethasone is recommended by international antiemesis guidelines for the prevention of chemotherapy-induced nausea and vomiting for patients receiving highly emetogenic chemotherapy and for select patients receiving moderately emetogenic chemotherapy. VARUBI (rolapitant) is a substance P/NK-1 RA that was recently approved by the U.S. Food and Drug Administration as an injectable emulsion in combination with other antiemetic agents in adults for the prevention of delayed nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including, but not limited to, highly emetogenic chemotherapy. Granisetron Hydrochloride Injection USP is one of the 5-HT3 RAs indicated for the prevention of nausea and/or vomiting associated with initial and repeat courses of emetogenic cancer therapy, including high-dose cisplatin. Herein, we describe the physical and chemical compatibility and stability of VARUBI (rolapitant) injectable emulsion (166.5 mg/92.5 mL [1.8 mg/mL], equivalent to 185 mg of rolapitant hydrochloride) admixed with Granisetron Hydrochloride Injection USP (1.0 mg/mL, equivalent to 1.12 mg/mL hydrochloride). Binary admixtures of VARUBI injectable emulsion and Granisetron Hydrochloride Injection USP were prepared and stored in VARUBI ready-to-use glass vials and in four types of commonly used intravenous administration (tubing) sets. Evaluation of the physical and chemical compatibility and stability of the admixtures in the VARUBI ready-to-use vials stored at room temperature (20°C to 25°C) under fluorescent light and under refrigeration (2°C to 8°C protected from light) was conducted at 0, 1, 6, 24, and 48 hours, and that of the admixtures in the intravenous tubing sets was evaluated at 0, 2, and 6 hours of storage at 20°C to 25°C. Physical stability was evaluated by visual examination

Purpose To assess the effect of intravenous contrast media on renal function in neonates. Materials and Methods Institutional review board approval was obtained with waiver of consent. Electronic health records from January 2011 to April 2013 were reviewed retrospectively. Measures of renal function were obtained in inpatient neonates who underwent magnetic resonance (MR) imaging or computed tomography (CT) and for whom serum creatinine (Cr) levels were obtained within 72 hours before imaging and at least one time after imaging (>1 day after administration of contrast material). A total of 140 neonates who received contrast material (59 who underwent CT with iohexol or iodixanol and 81 who underwent MR imaging with gadopentetate dimeglumine) were identified. These neonates were frequency matched according to sex, gestational and postnatal age, and preimaging serum Cr levels with neonates who underwent unenhanced MR imaging or CT. Cr levels and glomerular filtration rates (GFRs) were grouped according to when they were obtained (before imaging, 1-2 days after imaging, 3-5 days after imaging, 6-9 days after imaging, 10-45 days after imaging, and more than 45 days after imaging). Serum Cr levels and GFRs for each time period were compared between groups by using hierarchic regressions or χ 2 or Fisher exact tests and with repeated-measures analysis of variance to compare groups on the rate of change in serum Cr levels and GFRs from before to after imaging. Results Cr levels decreased and GFRs increased in both groups from before to after imaging (CT group, P ≤ .01; MR imaging group, P ≤ .01). The neonates who underwent contrast material-enhanced imaging and the neonates who underwent unenhanced imaging showed similar serum Cr levels at all examined time periods. Groups also did not differ in the proportion of neonates with serum Cr levels higher than the reference range (>0.4 mg/dL) at any time point (iodine- [P > .12] or gadolinium-based [P > .13] contrast

Full Text Available Hydrocarbons are ubiquitous in daily life and include plant and animal fats, alcohols, solvents, natural gas, petroleum derivates. Majority of intoxication reports of hydrocarbons are due to inhalation or ingestion, but there is few reports about intravenous injection of gasoline. We report a 58 year-old man who injected gasoline intravenously for suicide. He developed soft tissue necrosis of forearm and bilateral pulmonary infiltration. He underwent fasciotomy and extensive debridement of necrotic tissues, at the operation room. He was intubated and mechanically ventilated because of acute lung injury. He developed acute kidney injury after 2 days. These symptoms seem to be due to extravasation of gasoline from vessels which lead to inflammation, cell damage and organ failure. The patient developed multi organ failure which unfortunately did not respond to our treatment and he died at day 21. Management of gasoline intoxication depends on the rout of exposure. Like other types of toxications, intravenous toxication has pulmonary involvement, however in this case we had multiple organ involvement. It seems that in such cases we should consider early end organ targeted therapy to stop the future organ failure

Ischemic myocardial damage accompanying coronary artery bypass graft surgery remains a clinical challenge. We investigated whether xenon anesthesia could limit myocardial damage in coronary artery bypass graft surgery patients, as has been reported for animal ischemia models. In 17 university hospitals in France, Germany, Italy, and The Netherlands, low-risk elective, on-pump coronary artery bypass graft surgery patients were randomized to receive xenon, sevoflurane, or propofol-based total intravenous anesthesia for anesthesia maintenance. The primary outcome was the cardiac troponin I concentration in the blood 24 h postsurgery. The noninferiority margin for the mean difference in cardiac troponin I release between the xenon and sevoflurane groups was less than 0.15 ng/ml. Secondary outcomes were the safety and feasibility of xenon anesthesia. The first patient included at each center received xenon anesthesia for practical reasons. For all other patients, anesthesia maintenance was randomized (intention-to-treat: n = 492; per-protocol/without major protocol deviation: n = 446). Median 24-h postoperative cardiac troponin I concentrations (ng/ml [interquartile range]) were 1.14 [0.76 to 2.10] with xenon, 1.30 [0.78 to 2.67] with sevoflurane, and 1.48 [0.94 to 2.78] with total intravenous anesthesia [per-protocol]). The mean difference in cardiac troponin I release between xenon and sevoflurane was -0.09 ng/ml (95% CI, -0.30 to 0.11; per-protocol: P = 0.02). Postoperative cardiac troponin I release was significantly less with xenon than with total intravenous anesthesia (intention-to-treat: P = 0.05; per-protocol: P = 0.02). Perioperative variables and postoperative outcomes were comparable across all groups, with no safety concerns. In postoperative cardiac troponin I release, xenon was noninferior to sevoflurane in low-risk, on-pump coronary artery bypass graft surgery patients. Only with xenon was cardiac troponin I release less than with total intravenous

Flunixin meglumine is commonly used in horses for the treatment of musculoskeletal injuries. The current ARCI threshold recommendation is 20 ng/mL when administered at least 24 h prior to race time. In light of samples exceeding the regulatory threshold at 24 h postadministration, the primary goal of the study reported here was to update the pharmacokinetics of flunixin following intravenous administration, utilizing a highly sensitive liquid chromatography-mass spectrometry (LC-MS). An additional objective was to characterize the effects of flunixin on COX-1 and COX-2 inhibition when drug concentrations reached the recommended regulatory threshold. Sixteen exercised adult horses received a single intravenous dose of 1.1 mg/kg. Blood samples were collected up to 72 h postadministration and analyzed using LC-MS. Blood samples were collected from 8 horses for determination of TxB(2) and PGE(2) concentrations prior to and up to 96 h postflunixin administration. Mean systemic clearance, steady-state volume of distribution and terminal elimination half-life was 0.767 ± 0.098 mL/min/kg, 0.137 ± 0.12 L/kg, and 4.8 ± 1.59 h, respectively. Four of the 16 horses had serum concentrations in excess of the current ARCI recommended regulatory threshold at 24 h postadministration. TxB(2) suppression was significant for up to 24 h postadministration. © 2015 John Wiley & Sons Ltd.

Lipocalins tailored with high affinity for prescribed ligands, so-called anticalins, constitute promising candidates as antidotes. Here, we present an animal study to investigate both pharmacokinetic and clinical effects of an anticalin specific for the digitalis compound digoxin. Intravenous digoxin (2.5–50 μg/kg/min) was administered to rats until first changes in the ECG occurred (dose finding study) or a priori for 30 min (kinetic study). The anticalin DigA16(H86N), dubbed DigiCal, was administered intravenously at absolute doses of 1, 5, 10 and 20 mg, while the control group received isotonic saline. Hemodynamic changes, several ECG parameters and digoxin concentration in plasma were monitored at given time intervals. After DigiCal administration free digoxin concentration in plasma ultrafiltrate declined dramatically within 1 min to the presumably non-toxic range. There was also a significant and DigiCal dose-dependent effect on longer survival, less ECG alterations, arrhythmia, and improved hemodynamics. Infusion of a lower digoxin dose (2.5 μg/kg/min) resulted in a more sustained reduction of free digoxin in plasma after DigiCal administration compared to a higher digoxin dose (25 μg/kg/min), whereas ECG and hemodynamic parameters did not markedly differ, reflecting the known relative insensitivity of rats towards digoxin toxicity. Notably, we observed a re-increase of free digoxin in plasma some time after bolus administration of DigiCal, which was presumably due to toxin redistribution from tissue in combination with the relatively fast renal clearance of the rather small protein antidote. We conclude that anticalins with appropriately engineered drug-binding activities and, possibly, prolonged plasma half-life offer prospects for next-generation antidotal therapy. -- Highlights: ► We provide an advanced model of digoxin toxicity in rats. ► We report on binding of digoxin to a novel designed anticalin. ► We report on pharmacokinetics of digoxin

Full Text Available Introduction: Intravenous therapy is indicated for many reasons. A significant number of patients admitted into hospital receive some forms of intravenous therapy through peripheral venous cannula, which is a common procedure carried out in hospital to allow rapid and accurate administration of medication. However, the intravenous cannulation can have undesirable effects, the most of which is phlebitis, which is due to mechanical, chemical or infectious cause. Method: In this study quasi-experimental research approach was used. Non probability purposive sampling technique was used to select the sample from the selected hospital. The research design adopted for the study was pre-test, post-test control group design. In the present study a sample of 60 hospitalised patients and who met the inclusion criteria was selected from the target population. In this study the instruments used are baseline Performa, structured interview schedule to assess the subjective symptoms and observation scale to observe the objective symptoms. Result: In experimental group post test mean score 1.10, SD was 0.71 respectively. In control group post test mean score 2.53, SD was 0.78 respectively. The obtained value 7.454 statistically was significant at 0.001 levels. So research hypothesis was accepted. So there was significant difference between post intervention phlebitis among the experimental group and control group. Discussion: In the research study findings revealed that Glycerin Magnesium sulphate dressing is highly effective in decrease phlebitis level to the patients.

Kinsella, T.J.; Glatstein, E.

1987-01-01

Traditionally, adult bone and soft tissue sarcomas have been considered to be ''radioresistant.'' Because of this philosophy, patients who present with locally advanced, unresectable sarcomas often are treated in a palliative fashion, usually with low-dose radiotherapy. Over the last 6 years, 29 patients with unresectable primary or metastatic sarcomas were treated using a combination of intravenous chemical radiosensitizers and high-dose irradiation. Twenty-two of 29 patients achieved clinical local control, with six patients having a complete clinical response. The time to tumor response is often several months or longer, which is in contrast to other tumor histologies (carcinomas, lymphomas), where tumor response usually occurs over several weeks. Several large tumors have shown only a minimal tumor response, yet were found to be sterilized in posttreatment biopsy or autopsy examination. Of 15 patients with primary sarcomas without metastases, 11 patients (73%) remain free of local tumor progression from 12 to 83 months. Adult high-grade sarcomas can be controlled with high-dose radiotherapy and intravenous radiosensitizers, although the precise role of these agents is unclear

Full Text Available Objective:To analyze the problems existed in nursing students at different levels in the process of intravenous infusion, to make judgmental guide towards common problems in clinical teaching, to standardize nursing students’ operations at intravenous infusion, and to avoid errors and disputes. Methods: The authors analyzed the problems in secondary, tertiary, undergraduate nursing students in three levels at a provincial hospital from 2010 to 2012 during intravenous infusion therapy; and the clinical teaching administration means were also discussed. Results: the difference of the problems existed in nursing students at different levels is not significant. P values were greater than 0.05. The top five projects that lost scores are consistent. Conclusion: The key problems that can easily cause errors and disputes are those that mostly occurred in nursing students at intravenous infusion operations. In clinical teaching, judgmental guide on common problems should be emphasized, nursing students’ operations at intravenous infusion should be standardized, the critical awareness towards clinical operations should be developed, errors and disputes should be avoided, and nursing students’ sense of professionalism should be enhanced.

Paranoia is receiving increasing attention in its own right, since it is a central experience of psychotic disorders and a marker of the health of a society. Paranoia is associated with use of the most commonly taken illicit drug, cannabis. The objective was to determine whether the principal psychoactive ingredient of cannabis-∆(9)-tetrahydrocannabinol (THC)-causes paranoia and to use the drug as a probe to identify key cognitive mechanisms underlying paranoia. A randomized, placebo-controlled, between-groups test of the effects of intravenous THC was conducted. A total of 121 individuals with paranoid ideation were randomized to receive placebo, THC, or THC preceded by a cognitive awareness condition. Paranoia was assessed extensively via a real social situation, an immersive virtual reality experiment, and standard self-report and interviewer measures. Putative causal factors were assessed. Principal components analysis was used to create a composite paranoia score and composite causal variables to be tested in a mediation analysis. THC significantly increased paranoia, negative affect (anxiety, worry, depression, negative thoughts about the self), and a range of anomalous experiences, and reduced working memory capacity. The increase in negative affect and in anomalous experiences fully accounted for the increase in paranoia. Working memory changes did not lead to paranoia. Making participants aware of the effects of THC had little impact. In this largest study of intravenous THC, it was definitively demonstrated that the drug triggers paranoid thoughts in vulnerable individuals. The most likely mechanism of action causing paranoia was the generation of negative affect and anomalous experiences. © The Author 2014.

There is much experience with intoxication by aspiration of volatile hydrocarbon products, whereas intravenous injection of these distillates is rare. There are only few reports that describe a wide variety of associated pathological changes, predominantly in the pulmonary system. We report the case of an intravenous self-injection of gasoline by a young man in a suicide attempt. Immediately after injecting gasoline, the 22-year-old man developed bradycardia, hypotension, and increasing dyspnea. Computed tomography scan of the chest showed signs consistent with diffuse alveolar-toxic damage to the lung. These symptoms and radiological findings are similar to those commonly observed after inhalation of this type of substance. This may have been due to diffusion of gasoline into the alveoli, where its presence leads to this characteristic damage. In this patient, gasoline entered the intramuscular tissue, and the patient developed a soft-tissue phlegmon at the forearm. At operation, gas emanation and superficial necrosis were noted. Nevertheless, the patient's outcome was good, with full recovery within 3 weeks. The major changes in this patient after intravenous injection of gasoline were in the pulmonary system, including hypoxemia and radiological findings that could be related to an exhalation of the volatile substance. In addition, gas in the musculature of the injection area caused a soft-tissue phlegmon. Copyright © 2010 Elsevier Inc. All rights reserved.

Full Text Available Background and objectives: Tourniquet pain is one of the major obstacles for intravenous regional anesthesia. We aimed to compare tramadol and lornoxicam used in intravenous regional anesthesia as regards their effects on the quality of anesthesia, tourniquet pain and postoperative pain as well. Methods: After the ethics committee approval 51 patients of ASA physical status I–II aged 18–65 years were enrolled. The patients were divided into three groups. Group P (n = 17 received 3 mg/kg 0.5% prilocaine; group PT (n = 17 3 mg/kg 0.5% prilocaine + 2 mL (100 mg tramadol and group PL (n = 17 3 mg/kg 0.5% prilocaine + 2 mL (8 mg lornoxicam for intravenous regional anesthesia. Sensory and motor block onset and recovery times were noted, as well as tourniquet pains and postoperative analgesic consumptions. Results: Sensory block onset times in the groups PT and PL were shorter, whereas the corresponding recovery times were longer than those in the group P. Motor block onset times in the groups PT and PL were shorter than that in the group P, whereas recovery time in the group PL was longer than those in the groups P and PT. Tourniquet pain onset time was shortest in the group P and longest in the group PL. There was no difference regarding tourniquet pain among the groups. Group PL displayed the lowest analgesic consumption postoperatively. Conclusion: Adding tramadol and lornoxicam to prilocaine for intravenous regional anesthesia produces favorable effects on sensory and motor blockade. Postoperative analgesic consumption can be decreased by adding tramadol and lornoxicam to prilocaine in intravenous regional anesthesia.

Intravenous catheterization is frequently required for numerous medical treatments. However, this process is characterized by a high failure rate, especially when performed on difficult patients such as newborns and infants. Very young patients have small veins, and that increases the chances of accidentally puncturing the catheterization needle directly through them. In this article, we present the design, development and experimental evaluation of a novel hand-held robotic device for improving the process of peripheral intravenous catheterization by facilitating the needle insertion procedure. To our knowledge, this design is the first hand-held robotic device for assisting in the catheterization insertion task. Compared to the other available technologies, it has several unique advantages such as being compact, low-cost and able to reliably detect venipuncture. The system is equipped with an electrical impedance sensor at the tip of the catheterization needle, which provides real-time measurements used to supervise and control the catheter insertion process. This allows the robotic system to precisely position the needle within the lumen of the target vein, leading to enhanced catheterization success rate. Experiments conducted to evaluate the device demonstrated that it is also effective to deskill the task. Naïve subjects achieved an average catheterization success rate of 88% on a 1.5 mm phantom vessel with the robotic device versus 12% with the traditional unassisted system. The results of this work prove the feasibility of a hand-held assistive robotic device for intravenous catheterization and show that such device has the potential to greatly improve the success rate of these difficult operations.

To investigate effect of Compound Danshen Dripping Pill (CDDP) on the inflammatory response of the myocardium of acute myocardial infarction (AMI) rabbits, to observe the therapeutic effect of CDDP combined intravenous transplantation of human umbilical cord blood mononuclear cells (HUCBMCs) on inflammatory response, pro-inflammatory cytokine tumor necrosis factor alpha (TNF-alpha) , and heart function in the myocardium of AMI rabbits, and to explore the possible protective mechanisms of the combined therapy. The AMI model was successfully established by ligation of the left anterior coronary artery (LAD) in 40 healthy rabbits.Then they were randomly divided into four groups, i.e., the control group, the CDDP group, the transplantation group, and the combined group, 10 in each group. Rabbits in the control group received intravenous injection of 0.5 mL normal saline via ear vein within 24 h after AMI and then intragastric infusion of normal saline at 5 mL per day. Rabbits in the CDDP group received intravenous injection of 0.5 mL normal saline via ear vein within 24 h after AMI and then intragastric infusion of solution obtained by solving 270 mg CDDP in 5 mL normal saline per day. Rabbits in the transplantation group received intravenous injection of 0.5 mL normal saline labeled with green fluorescent protein (GFP) containing 3 x 10(7) of HUCBMCs via ear vein within 24 h after AMI and then intragastric infusion of normal saline at 5 mL per day. Rabbits in the combined group received intravenous injection of 0.5 mL normal saline labeled with GFP containing 3 x 10(7) of HUCBMCs via ear vein within 24 h after AMI and then intragastric infusion of solution obtained by solving 270 mg CDDP in 5 mL normal saline per day. At week 1 and 4 after treatment, cardiac function indices such as left ventricular fractional shorting (LVFS) and left ventricular ejection fraction (LVEF) were performed by echocardiography; the number of transplanted cells in the myocardium was found

A prospective randomised trial comparing nasogastric with intravenous hydration in children with bronchiolitis (protocol) The comparative rehydration in bronchiolitis study (CRIB)

2010-01-01

Background Bronchiolitis is the most common reason for admission of infants to hospital in developed countries. Fluid replacement therapy is required in about 30% of children admitted with bronchiolitis. There are currently two techniques of fluid replacement therapy that are used with the same frequency-intravenous (IV) or nasogastric (NG). The evidence to determine the optimum route of hydration therapy for infants with bronchiolitis is inadequate. This randomised trial will be the first to provide good quality evidence of whether nasogastric rehydration (NGR) offers benefits over intravenous rehydration (IVR) using the clinically relevant continuous outcome measure of duration of hospital admission. Methods/Design A prospective randomised multi-centre trial in Australia and New Zealand where children between 2 and 12 months of age with bronchiolitis, needing non oral fluid replacement, are randomised to receive either intravenous (IV) or nasogastric (NG) rehydration. 750 patients admitted to participating hospitals will be recruited, and will be followed daily during the admission and by telephone 1 week after discharge. Patients with chronic respiratory, cardiac, or neurological disease; choanal atresia; needing IV fluid resuscitation; needing an IV for other reasons, and those requiring CPAP or ventilation are excluded. The primary endpoint is duration of hospital admission. Secondary outcomes are complications, need for ICU admission, parental satisfaction, and an economic evaluation. Results will be analysed using t-test for continuous data, and chi squared for categorical data. Non parametric data will be log transformed.

Five patients treated with intraperitoneal 131I-labeled mouse monoclonal antibody for ovarian cancer also received i.v. exogenous polyclonal human anti-murine immunoglobulin antibody. The pharmacokinetics of 131I-labeled monoclonal antibody in these patients were compared with those of 28 other patients receiving i.p.-radiolabeled monoclonal antibody for the first time without exogenous human anti-murine immunoglobulin, and who had no preexisting endogenous human anti-murine immunoglobulin antibody. Patients receiving i.v. human anti-murine immunoglobulin antibody demonstrated a rapid clearance of 131I-labeled monoclonal antibody from their circulation. The (mean) maximum 131I blood content was 11.4% of the injected activity in patients receiving human anti-murine immunoglobulin antibody compared to 23.3% in patients not given human anti-murine immunoglobulin antibody. Intravenous human anti-murine immunoglobulin antibody decreased the radiation dose to bone marrow (from 131I-labeled monoclonal antibody in the vascular compartment) 4-fold. Following the injection of human anti-murine immunoglobulin antibody, 131I-monoclonal/human anti-murine immunoglobulin antibody immune complexes were rapidly transported to the liver. Antibody dehalogenation in the liver was rapid, with 87% of the injected 131I excreted in 5 days. Despite the efficient hepatic uptake of immune complexes, dehalogenation of monoclonal antibody was so rapid that the radiation dose to liver parenchyma from circulating 131I was decreased 4-fold rather than increased. All patients developed endogenous human anti-murine immunoglobulin antibody 2 to 3 weeks after treatment

The study aimed to compare efficacy, safety, pain intensity and analgesic consumption in patients receiving either bilateral transversus abdominis plane (TAP) block or wound infiltration with bupivacaine after cesarean delivery (CD). A total of 216 parturient women undergoing CD under general anesthesia were randomly allocated into five groups: i) controls (group 1), ii) TAP placebo (group 2), iii) TAP (group 3), iv) wound infiltration placebo (group 4), and, v) wound infiltration (group 5). Pain intensity was assessed using a visual analogue scale (VAS). Analgesic consumptions were recorded by a blinded nurse at 6, 12, and 18 hours postoperatively. The baseline characteristics of the five groups were similar in terms of age, history of CD, and body mass indices (p>0.05). There were significant intergroup differences in VAS scores between all groups at the zero time-point (p=0.03), at the 6th hour (p=0.02), 12th hour (p=0.02), and at the 18th hour (p=0.02). Group 3 patients had lower pain scores and consumed less diclofenac than group 2 patients only within 12 hours postoperatively whereas pain intensity and analgesic consumption were not different between group 5 and group 4 patients. Group 5 patients received significantly less pethidine than group 4 and group 1 patients (p<0.001). TAP block provided better pain relief and less analgesic requirement than bupivacaine wound infiltration early after CD. Given the similar amounts of diclofenac but lower amounts of pethidine administered in the wound infiltration group, wound infiltration of bupivacaine seems promising in terms of reducing opioid use after CD under general anesthesia, especially when TAP block is not used.

To review the pharmacology, pharmacokinetics, efficacy, safety, dosage and administration, potential drug-drug interactions, and place in therapy of the intravenous (IV) formulation of carbamazepine (Carnexiv) for the treatment of seizures in adult patients. A comprehensive PubMed and EBSCOhost search (1945 to August 2017) was performed utilizing the keywords carbamazepine, Carnexiv, carbamazepine intravenous, IV carbamazepine, seizures, epilepsy, and seizure disorder. Additional data were obtained from literature review citations, manufacturer's product labeling, and Lundbeck website as well as Clinicaltrials.gov and governmental sources. All English-language trials evaluating IV carbamazepine were analyzed for this review. IV carbamazepine is FDA approved as temporary replacement therapy for treatment of adult seizures. Based on a phase I trial and pooled data from 2 open-label bioavailability studies comparing oral with IV dosing, there was no noted indication of loss of seizure control in patients switched to short-term replacement antiepileptic drug therapy with IV carbamazepine. The recommended dose of IV carbamazepine is 70% of the patient's oral dose, given every 6 hours via 30-minute infusions. The adverse effect profile of IV carbamazepine is similar to that of the oral formulation, with the exception of added infusion-site reactions. IV carbamazepine is a reasonable option for adults with generalized tonic-clonic or focal seizures, previously stabilized on oral carbamazepine, who are unable to tolerate oral medications for up to 7 days. Unknown acquisition cost and lack of availability in the United States limit its use currently.

The study included 10 patients with right-sided IE in conjunction with HIV/AIDS. All patients were male, age – from 28to 36 years.Results. Course of the IE in HIV/AIDS among intravenous drugs abused in general corresponds to features specific to IE in intravenous drug users without HIV infection. Distinctive features of IE in these patients are a large burden of lung disease, its disseminated character, more tissue oxygenation disorders and marked pulmonary hypertension and haematological disorders (lymphopenia, anemia, and late diagnosis of IE.Conclusion. Features of the current right-sided IE in intravenous drugs abused with HIV/AIDS are distinguished . Difficulties in diagnosis of IE inHIV infection are due to variety of causes of prolonged fever, which should guide doctors to more frequent use of transthoracic echocardiography during prolonged fever in HIV-infected patients.
