    2014-07-01

    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.

    Human intravenous immunoglobulin (IGIV) has been in use for the past 20 years. This biological product is commonly provided in liquid or lyophilized dosage form. When the lyophilized product is rehydrated, it is usually administered within 2-3 h from time of complete dissolution. While this practice is advisable whenever possible, occasionally the patient or care-giver may need to delay the infusion. Hence, a study of the stability of lyophilized IGIV after reconstitution with water for injection was conducted. The reconstituted product was stored either in its original glass container or pooled into poly(vinyl chloride) (PVC) bags. The effect of extended storage on the active ingredient (IgG), excipients (glucose, albumin) and extractables [sodium from glass vials, and di-(2-ethyl-hexyl) phthalate and cyclohexanone from PVC bags] was evaluated. The stability of the active ingredient was evaluated by physico-chemical tests (molecularsize distribution, pH, appearance, total protein), monitoring titres of a specific antibody (hepatitis B surface antigen) and an antibody functional test (bacterial opsonization). To evaluate the risk of microbial contamination during reconstitution and pooling procedures, sterility, pyrogen and animal-safety tests were included in the protocol. The potential of IgG polymerizing in solution during storage and subsequent complement activation was evaluated by assaying for non-specific binding of complement (anti-complement activity). Results show that aseptically reconstituted IGIV is stable and remains sterile up to 48 h at 5 degrees C. The reconstituted product was also found to be stable at room temperature (25 degrees C) up to 12 h.

    Intravenous (IV) infusions of telavancin for injection are generally administered in-hospital, but in some circumstances they may be administered in an outpatient environment. In that setting, antibiotics may be premixed and frozen. This study determined the chemical stability of nonpreserved telavancin in various commonly used reconstitution diluents stored in IV bags (polyvinyl chloride [PVC] and PVC-free) at -20°C (-4°F) without light. Telavancin (750 mg/vial) was reconstituted with 5% dextrose injection USP (D5W) or 0.9% sodium chloride injection USP (NS) to obtain drug solutions at approximately 15 mg/mL. Infusion solutions of telavancin at diluted concentrations of 0.6 mg/mL and 8.0 mg/mL covering the range utilized in clinical practice were prepared in both PVC and PVC-free IV bags using D5W or NS solutions. The infusion solutions were stored under frozen conditions (-20°C ± 5°C [-4°F ± 41°F]) and the chemical stability was evaluated for up to 32 days. Telavancin concentration, purity, and degradant levels were determined using a stability-indicating high-performance liquid chromatography (HPLC) method. Telavancin IV infusion solutions in D5W or NS at 0.6 mg/mL and 8 mg/mL and stored at -20°C (-4°F) met the chemical stability criteria when tested on days 0, 7, 14, and 32. The assayed telavancin concentration at each time point was within 97% to 103% of the initial mean assay value. The total degradants quantified by the HPLC stability-indicating method did not show any significant change over the 32-day study period. Telavancin IV infusion solutions (in D5W or NS) in both PVC and PVC-free IV bags were stable for at least 32 days when stored at -20°C (-4°F) without light. These results provide prolonged frozen stability data further to that previously established for 7 days under refrigerated conditions (2°C-8°C [36°F -46°F]), and for 12 hours at room temperature when diluted into IV bags containing D5W, NS, or lactated Ringer's solution.

    Full Text Available P Brandon Bookstaver, April D Miller, Celeste N Rudisill, LeAnn B NorrisDepartment of Clinical Pharmacy and Outcomes Sciences, South Carolina College of Pharmacy, University of South Carolina Campus, Columbia, South Carolina, USAAbstract: This paper reviews the current data on the use of the first approved intravenous ibuprofen product for the management of post-operative pain and fever in the United States. The management of acute and post-operative pain and fever with nonsteroidal anti-inflammatory agents (NSAIDs is well documented. A search in Medline and International Pharmaceutical Abstracts of articles until the end of November 2009 and references of all citations were conducted. Available manufacturer data on file were also analyzed for this report. Several randomized controlled studies have demonstrated the opioid-sparing and analgesic effects of 400 and 800 mg doses of intravenous ibuprofen in a series of post-operative patient populations. Two recent studies have also noted the improvement in fever curves in critically ill and burn patients. These data, along with pharmacokinetic and pharmacologic properties, are explored in this review, which addresses the clinical utility of a parenteral NSAID in a hospitalized patient for post-operative pain management and fever reduction. Further data on intravenous ibuprofen are needed to define long-term utilization, management of acute pain, and use in special populations.Keywords: ibuprofen, intravenous, injectable, nonsteroidal anti-inflammatory drug

    The worldwide seroprevalence of hepatitis A virus (HAV) and hepatitis B virus (HBV) has changed over the last two decades, indicating a declining incidence of HAV and HBV infections. Therefore, vaccinations against HAV and HBV are recommended for unimmunized people before traveling to an endemic area. Unfortunately, primary antibody deficiency (PAD) patients can only obtain humoral immunity through intravenous immunoglobulin G (IVIG) replacement and not from vaccination because of a defect in antibody production. However, few studies have analyzed the titers of antibodies against HAV or HBV in IVIG products. In this study, the titers of anti-HAV and anti-HBs antibodies were measured in nineteen lots of IVIG products from five manufacturers from three countries (A, B from Korea; C, D from Japan; and E from the USA), and trough titers in plasma were estimated. Concentrations of anti-HAV antibody ranged from 1,888-8,927 mIU/mL and estimated trough titers exceeded the minimal protective value in all evaluated IVIG products. Concentrations of anti-HBs antibody ranged from 438-965 mIU/mL in products A and B and were 157, 123, and 1,945 mIU/mL in products C, D, and E, respectively. Estimated trough titers in products A, B, and E exceeded the minimal protective value but those in products C and D did not reach this threshold. These data demonstrated that available IVIG products generally provide sufficient antibodies against HAV and HBV to protect patients with PAD, although the trough concentrations of anti-HBs antibody in two IVIG products did not reach the minimum protective value.

    Full Text Available Immunoglobulin G (IgG of excellent quality for intravenous use was obtained from the cryosupernatant of human plasma by a chromatographic method based on a mixture of ion-exchange, DEAE-Sepharose FF and arginine Sepharose 4B affinity chromatography and a final purification step by Sephacryl S-300 HR gel filtration. The yield of 10 experimental batches produced was 3.5 g IgG per liter of plasma. A solvent/detergent combination of 1% Tri (n-butyl phosphate and 1% Triton X-100 was used to inactivate lipid-coated viruses. Analysis of the final product (5% liquid IgG based on the mean for 10 batches showed 94% monomers, 5.5% dimers and 0.5% polymers and aggregates. Anticomplementary activity was 0.3 CH50/mg IgG and prekallikrein activator levels were less than 5 IU/ml. Stability at 37ºC for 30 days in the liquid state was satisfactory. IgG was stored in flasks (2.5 g/flask at 4 to 8ºC. All the characteristics of the product were consistent with the requirements of the 1997 Pharmacopée Européenne.

    Lin, Alex C; Penm, Jonathan; Ivey, Marianne F; Deng, Yihong; Commins, Monica

    This study aims to use lean techniques and evaluate the impact of increasing the use of premixed IV solutions and increased IV production frequency on IV waste. Study was conducted at a tertiary hospital pharmacy department in three phases. Phase I included evaluation of IV waste when IV production occurred three times a day and eight premixed IV products were used. Phase II increased the number of premixed IV products to 16. Phase III then increased IV production to five times a day. During Phase I, an estimate of 2,673 IV doses were wasted monthly, accounting for 6.14% of overall IV doses. This accounted for 688 L that cost $60,135. During Phase II, the average monthly IV wastage reduced significantly to 1,069 doses (2.84%), accounting for 447 L and $34,003. During Phase III, the average monthly IV wastage was further decreased to 675 doses (1.69%), accounting for 78 L and $3,431. Hence, a potential annual saving of $449,208 could result from these changes. IV waste was reduced through the increased use of premixed solutions and increasing IV production frequency.

    Full Text Available Dengue represents an important health problem in Brazil and therefore there is a great need to develop a vaccine or treatment. The neutralization of the dengue virus by a specific antibody can potentially be applied to therapy. The present paper describes, for the first time, the preparation of Immunoglobulin specific for the dengue virus (anti-DENV IgG, collected from screened Brazilian blood-donations. Production was performed using the classic Cohn-Oncley process with minor modifications. The anti-DENV IgG was biochemically and biophysically characterized and fulfilled the requirements defined by the European Pharmacopoeia. The finished product was able to neutralize different virus serotypes (DENV-1, DENV-2, and DENV-3, while a commercial IgG collected from American blood donations was found to have low anti-dengue antibody titers. Overall, this anti-DENV IgG represents an important step in the study of the therapeutic potential and safety of a specific antibody that neutralizes the dengue virus in humans.

  13. Intravenous immunoglobulin prevents murine antibody-mediated acute lung injury at the level of neutrophil reactive oxygen species (ROS production.

    Directory of Open Access Journals (Sweden)

    John W Semple

    Full Text Available Transfusion-related acute lung injury (TRALI is a leading cause of transfusion-associated mortality that can occur with any type of transfusion and is thought to be primarily due to donor antibodies activating pulmonary neutrophils in recipients. Recently, a large prospective case controlled clinical study of cardiac surgery patients demonstrated that despite implementation of male donors, a high incidence of TRALI still occurred and suggested a need for additional interventions in susceptible patient populations. To examine if intravenous immunoglobulin (IVIg may be effective, a murine model of antibody-mediated acute lung injury that approximates human TRALI was examined. When BALB/c mice were injected with the anti-major histocompatibility complex class I antibody 34-1-2s, mild shock (reduced rectal temperature and respiratory distress (dyspnea were observed and pre-treatment of the mice with 2 g/kg IVIg completely prevented these symptoms. To determine IVIg's usefulness to affect severe lung damage, SCID mice, previously shown to be hypersensitive to 34-1-2s were used. SCID mice treated with 34-1-2s underwent severe shock, lung damage (increased wet/dry ratios and 40% mortality within 2 hours. Treatment with 2 g/kg IVIg 18 hours before 34-1-2s administration completely protected the mice from all adverse events. Treatment with IVIg after symptoms began also reduced lung damage and mortality. While the prophylactic IVIg administration did not affect 34-1-2s-induced pulmonary neutrophil accumulation, bone marrow-derived neutrophils from the IVIg-treated mice displayed no spontaneous ROS production nor could they be stimulated in vitro with fMLP or 34-1-2s. These results suggest that IVIg prevents murine antibody-mediated acute lung injury at the level of neutrophil ROS production and thus, alleviating tissue damage.

    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.

    This study examines the feasibility of deriving the 24-h insulin requirement of insulin-dependent diabetic patients who were devoid of any endogenous insulin release (IDD) from the insulin-production rate (IPR) of healthy man (basal, 17 mU/min; stimulated 1.35 U/12.5 g glucose). To this end, continuous intravenous insulin infusion (CIVII) was initiated at a precalculated rate of 41.2 +/- 4.6 (SD) U/24 h in IDD (N - 12). Blood glucose profiles were compared with those obtained during intermittent subcutaneous (s.c.) insulin therapy (IIT) and those of healthy controls (N = 7). Regular insulin (Hoechst CS) was infused with an adapted Mill Hill Infuser at a basal infusion rate of 1.6 U/h (6:00 a.m. to 8:00 p.m.), and of 0.8 U/h from 8:00 p.m. to 6:00 a.m. Preprandial insulin (3.2-6.4 U) was added for breakfast, lunch, and dinner. Daily individual food intake totaled 7688 +/- 784 kJ (1836 +/- 187 kcal)/24 h including 184 +/- 37 g of glucose. Proper control of blood glucose (BG) (mean BG 105 +/- 10 mg/dl; mean amplitude of glycemic excursions 54 +/- 18 mg/dl; and 1 h postprandial BG levels not exceeding 160 mg/dl) and of plasma concentrations of beta-hydroxybutyrate and lactate was maintained by 41.4 +/- 4.4 U insulin/24 h. Although BG values only approximated the upper normal range as seen in healthy controls, they were well within the range reported by others during CIVII. Therefore, we conclude that in adult IDD completely devoid of endogenous insulin (1) the IPR of normal man can be used during CIVII as an estimate for the patient's minimal insulin requirement per 24 h, and (2) this approach allows for a blood glucose profile close to the upper range of a normal control group. Thus, deriving a patient's daily insulin dose from the insulin production rate of healthy man may add an additional experimental protocol which aids in making general calculations of a necessary insulin dose instead of using trial and error or a closed-loop insulin infusion system.

    1997-01-01

    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)

  1. Ultrasonography versus intravenous urography

    Aslaksen, A.

    1991-01-01

    The present study was performed to compare the clinical value of urography and ultrasonography in a non-selected group of patients referred for urography to a university hospital. The conslusions and clinical implications of the study are as follows: Intravenous urography remains the cornerstone imaging examination in the evaluation of ureteral calculi. Ultrasonography is a valuable adjunct in cases of non- visualization of the kidneys, in distal obstruction and known contrast media allergy. When women with recurrent urinary tract infection are referred for imaging of the urinary tract, ultrasonography should be used. Ultrasonography should replace urography for screening of non-acute hydronephrosis like in female genital cancer and benign prostate hyperplasia. There is good correlation between urography and ultrasonography in assessing the degree of hydronephrosis. However, more researh on the relationship between hydronephrosis and obstruction is necessary. Ultrasonography should be used as the only imaging method of the upper urinary tract in patients with microscopic hematuria. In patients less than 50 years with macroscopic hematuria, ultrasonography should be used as the only imaging of the upper urinary tract, and an examination of the urinary bladder should be included. In patients over 50 years, urography supplied with ultrasonography should be used, but more research is necessary on the subject of imaging method and age. 158 refs

    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.

    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.

    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

    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.

    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.

    2013-01-01

    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.

    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.

    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.

    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.

    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.

    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.

  13. Contrast agent choice for intravenous coronary angiography

    International Nuclear Information System (INIS)

    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

  14. Intravenous Lipids for Preterm Infants: A Review

    Directory of Open Access Journals (Sweden)

    Ghassan S. A. Salama

    2015-01-01

    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.

    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.

    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.

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)

    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

    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.

    Intravenous immunoglobulin (IVIG) has been used as antibody replacement therapy in primary immunodeficiency diseases (PIDDs) for more than 50 years. Its role as a therapeutic agent has expanded over the past couple of decades as its anti-inflammatory and immune-modulatory mechanisms of action have been elucidated. It is now used "off-label" to treat other autoimmune diseases. This article focuses on the role of IVIG in the treatment of PIDDs characterized by absent or deficient antibody production. Replacement doses are given on a monthly basis in these conditions as a prophylactic measure to prevent acute and serious bacterial infections. [Pediatr Ann. 2017;46(1):e8-e12.].

    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.

  5. A tomographic approach to intravenous coronary arteriography

    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

    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.

  8. Adverse reactions to iotroxate at intravenous cholangiography

    1987-01-01

    The number and type of adverse reactions to meglumine iotroxate at intravenous infusion cholangiography, performed one day prior to elective cholecystectomy, were recorded in a prospective investigation of 196 asymptomatic, anicteric patients. One hundred ml (50 mg I/ml) of contrast medium was infused over a period of 30 minutes. Only 2 minor (1%) and no severe or fatal reactions were noted. A review of the literature on the use of iotroxate in 2492 patients, including those in the present investigation, revealed a complication rate of 3.5% (3.0% minor, 0.3% moderate and 0.2% severe reactions) at infusion of iotroxate (5.0-8.0 g I) over a period of 30 to 120 minutes. This compared favourably with the 5% complication rate (4% minor, 0.5% moderate and 0.5% severe reactions) at infusion of iodoxamate and the 9% complication rate (5% minor, 1% moderate and 3% severe reactions) at infusion of ioglycamide. Irrespective of the contrast agent used, the frequency of adverse reactions at infusion was found to be 3 times lower than when equal amounts (5.0-5.6 g I) of the same medium were injected. It is concluded that, at present, infusion of iotroxate in an amount which approximates to the transportation maximum of the liver is the least toxic way of performing intravenous cholangiography with an optimum filling of the bile ducts.

  9. Intravenous dynamic nucleography of the brain

    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.)

    Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease with diverse manifestations. We suggest that intravenous immunoglobulin (IVIg) therapy may be beneficial and safe for various manifestations in SLE. A structured literature search of articles published on the efficacy of IVIg in the treatment of SLE between 1983 and 2005 was conducted. We searched the terms "IVIg," "intravenous immunoglobulin," "lupus," "SLE," and "systemic lupus erythematosus." The various clinical manifestations of SLE that were reported to be successfully treated by IVIg in case reports include autoimmune hemolytic anemia, acquired factor VIII inhibitors, acquired von Willebrand disease, pure red cell aplasia, thrombocytopenia, pancytopenia, myelofibrosis, pneumonitis, pleural effusion, pericarditis, myocarditis, cardiogenic shock, nephritis, end-stage renal disease, encephalitis, neuropsychiatric lupus, psychosis, peripheral neuropathy, polyradiculoneuropathy, and vasculitis. The most extensive experience is with lupus nephritis. There are only a few case series of IVIg use in patients with SLE with various manifestations, in which the response rate to IVIg therapy ranged from 33 to 100%. We suggest that IVIg devoid of sucrose, at a dose of 2 g/kg over a 5-d period given uniformly and at a slow infusion rate in patients without an increased risk for thromboembolic events or renal failure, is a safe and beneficial adjunct therapy for cases of SLE that are resistant to or refuse conventional treatment. The duration of therapy is yet to be established. Controlled trials are warranted.

    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.

    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

    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.

    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.

    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.

    Cytomegalovirus (CMV) remains one of the most important pathogens after transplantation, potentially leading to CMV disease, allograft dysfunction, acute, and chronic rejection and opportunistic infections. Immunoglobulin G (IgG) preparations with high antibody titers against CMV are a valuable adjunctive prevention and treatment option for clinicians and apart from standard intravenous immunoglobulin (IVIG), CMV hyperimmune preparations are available. The CMV antibody titer of these preparations is typically determined by Enzyme-linked immunosorbent assay (ELISA), also used for the selection of high titer plasma donors for the production of the CMV Hyperimmune product. However, CMV ELISA titers do not necessarily correlate with CMV antibody function which is determined by virus neutralization tests. CMV antibody titers were determined by both ELISA and virus neutralization assay and the IgG subclass distribution was compared between a CMV hyperimmune licensed in Europe and standard IVIG preparations. Although the expected high CMV IgG ELISA antibody titers were confirmed for three lots of a CMV hyperimmune preparation, the functionally more relevant CMV neutralizing antibody titers were significantly higher for 31 lots of standard IVIG preparations. Moreover, considerably lower IgG3 levels were found for the CMV hyperimmune preparation compared with standard IVIG preparations. The higher functional CMV neutralization titers of standard IVIG preparations and the better availability of these preparations, suggest that these products could be a valuable alternative to the CMV hyperimmune preparation.

  1. Solar urticaria successfully treated with intravenous immunoglobulin.

    2012-02-01

    Idiopathic solar urticaria (SU) is a rare, debilitating photodermatosis, which may be difficult to treat. First-line treatment with antihistamines is effective in mild cases, but remission after phototherapeutic induction of tolerance is often short-lived. Other treatment options include plasma exchange, photopheresis and cyclosporin. We present two cases of severe, idiopathic SU, which were resistant to conventional treatment. Both patients achieved remission after administration of intravenous immunoglobulin (IVIg) and have remained in remission at 13 months and 4 years, respectively. There are only two case reports of successful treatment of solar urticaria with IVIg. In our experience IVIg given at a total dose of 2 g\\/kg over several 5-day courses about a month apart is an effective treatment option for severe idiopathic SU. It is also generally safe, even if certainly subject to significant theoretical risks, such as induction of viral infection or anaphylaxis.

    2007-02-01

    Amyloid-beta peptide (Abeta) contributes to the acute progression of Alzheimer's disease (AD) and has become the main target for therapeutics. Active immunization with Abeta in individuals with AD has been efficacious; however, some patients developed side effects, possibly related to an autoimmune response. Evidence that intravenous immunoglobulin (IVIg), an FDA-approved purified immunoglobulin fraction from normal human donor blood, shows promise of passive immunotherapy for AD is reviewed. Investigations into the molecular effects of IVIg on Abeta clearance, using the BV-2 cellular microglia line, demonstrate that IVIg dissolves Abeta fibrils in vitro, increases cellular tolerance to Abeta, enhances microglial migration toward Abeta deposits, and mediates phagocytosis of Abeta. Preliminary clinical results indicate that IVIg, which contains natural antibodies against the Abeta, warrants further study into its potential to deliver a controlled immune attack on the peptide, avoiding the immune toxicities that have had a negative impact on the first clinical trials of vaccine against Abeta.

    This report derives from Tromsoe in northern Norway. In a retrospective study of the indications for intravenous urography (IU) and the findings at IU in 740 patients (451 girls and 289 boys) aged 0-19 years, we found that urinary tract infections accounted for 69.4% of the IU in females and 30.1% of the IU in males, most often seen in the youngest patients. The pathological findings most frequently seen were anomalies (17 females and 10 males) and urinary tract obstruction (3 females and 15 males). The present study indicates the following: first, that the yield of IU in the primary investigation of children and youth suffering from enuresis and non-specific abdominal disturbancies is small; and second, that the use of IU in children and youth with urinary tract infection and haematuria should be questioned and reconsidered.

    1980-01-01

    Intravenous urography (IVU) as it is used widely today was probably started in early 1950's after the introduction of triiodobenzoic acid compounds as contrast media. This long cherished traditional method consists of taking radiograms at 5, 15 and 25 minutes after the injection of contrast medium. There are a few modifications of this standard urographic examination such as five minute IVU (Woodruff, 1959), minute-sequence pyelogram (Maxwell et al., 1964), drip infusion pyelography (Schencker, 1964) and nephrotomography (Evans et al., 1955). The present study has been undertaken to test if the conventional standard IVU can be more rapidly performed without losing essential informational contents of urograms. In this new clinical trial, urograms were taken at the end of 1, 3 and 7 minutes instead of 5, 15 and 25 minutes after the intravenous injection of contrast medium. We injected 40 ml of meglumine diatrizoate solution within 30 seconds using an 18G iv needle. (The amount of injected contrast medium has been reduced recently to ordinary single dose of 20 ml for subjects weighing less than 8 kg). Upon viewing the 7 minute film in front of an automatic processor, the examination was terminated after obtaining an upright view unless any further radiogram was indicated. As shown in Tables and Figures, our new 1-3-7 minute method has been proven to provide us with as much essential and useful information as conventional 5-15-25 minute urography. Thus, we were able to finish one examination within 10 minutes without losing any necessary diagnostic information. In some of patients with obstructive uropathy such as stone the examination was extended as long as it was desired. Side reactions were occasional nausea, flushing and rare mild vomiting which never prevented the examination

    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.

    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%).

    This review described the progress and current status of intravenous coronary angiography (IVCAG) using the orbital radiation generated by the synchrotron. Authors diagnosed 4 patients of coronary artery disease in 1996 and 33 until 2000. Monochromatic 2-D X-ray beam (2.0 X 10{sup 10} photons/mm{sup 2}/sec, 130 X 75 mm) of 37 keV was obtained by non-symmetrical reflection of synchrotron radiation generated by 5.0 GeV accelerated electron. The use of 2-D beam enabled to give the dynamic IVCAG image in contrast with the static image by the 1-D slit beam. Intermittent irradiation (5 msec/100 msec) reduced the exposure dose to <750 mSv. Images were recorded in the Sony digital video-recorder placed behind the Sony Charge-coupled device (CCD) camera and Toshiba photo-multiplier, and gave the precision of 1 mm of the artery. The IVCAG by synchrotron radiation reduced patients' burden and was expected to be more widely used in future. (K.H.)

    Effects of intravenous ioxilan, a new third generation non-ionic contrast medium, diatrizoate, iohexol and saline on urine profiles were compared. Albumin, glucose, sodium, phosphate, and the enzymes NAG, LDH and GGT were followed in 24 normal rats over 7 days. Diatrizoate significantly affected all profile components during the first two hours. Albuminuria was significantly greater after diatrizoate than after iohexol or ioxilan, and excretion of glucose, LDH and GGT was significantly higher than after ioxilan. Both iohexol and ioxilan increased the excretion of albumin, LDH and GGT, while iohexol also significantly increased excretion of glucose and sodium. There was a greater excretion of glucose and GGT after iohexol than after ioxilan. Saline did not induce any changes. At day 7, serum sodium, urea, creatinine, and albumin were normal for all test substances, and kidney histology revealed no difference between the groups of animals. It is thus concluded that both high osmolar ionic and low osmolar non-ionic contrast media may cause temporary glomerular and tubular dysfunction in rats. In this model, the kidney is affected most by diatrizoate, less by iohexol, and least by ioxilan. (orig.)

    In a prospective study of 103 patients the incidence of cardiac events during intravenous digital subtraction angiography (i.v. DSA) was investigated. Of 103 patients 17 had known ischaemic heart disease. The examination was performed with an ionic contrast medium, Urografin 76% (sodium megluminediatrizoate), administered by bolus injection into the right atrium. Patients with severe cardiac disease were examined only if the procedure was considered of vital importance. Cardiac events were defined as ST-segment changes of more than 0.1 mV, changes in heart rate of more than 20%, arrhythmias and such symptoms as chest pain and dyspnoea. Ischaemic ST-segment changes during i.v. DSA were observed in approximately 20% of the patients and were not related to the presence of known ischaemic heart disease. Three patients developed angina during the procedure. Among 12 patients with known angina only one patient developed angina during the procedure. In this study chest pain was infrequent (3%), but there was a relative high frequency of ECG changes (20%) not related to patients with ischaemic heart disease only. It is concluded that there is a risk of cardiac events during i.v. DSA, but the risk is not increased in patients with known ischaemic heart disease (if they do not suffer from congestive heart failure) as compared with other patients without known ischaemic heart disease.

    Full Text Available Background. Parenteral drug abuse is the most common cause of infected femoral artery pseudoaneurysms (IFAP. This complication of intravenous drug abuse is not only limb threatening but can also be life threatening. The management of the IFAP is difficult and controversial. Generally speaking, ligation and excision of the pseudoaneurysm without revascularization is accepted procedure in majority of the patients. However it is not regarded as an appropriate procedure for cases where the high probability of amputation is expected from acute interruption of the femoral artery flow.Patients, methods and results. We present three cases of young (average 20 years, range 18–24 patients with IFAP, in which a primary reconstruction was performed due to absence of doppler signal over pedal arteries after ligation of common femoral artery. In two of them complications in form of haemorrhage and repeated infection developed in late postoperative period. The first one, had an excision and ligation while the second one had a reconstruction made by means of a silver impregnated dacron prosthesis. None of the patients required an amputation.Conclusions. Overall prognosis and prognosis of the reconstruction in parenteral drug abuse patients is uncertain because there is a high incidence of postoperative drug injection despite aggressive drug rehabilitation.

    Intravenous pyelography (IVP) and micturition cystourethrography (MCU) are the standard procedures in the radiological examination of children with urinary tract infections and in the control of these children. Gonad protection against radiation is not possible in MCU, but concerning the girls partly possible in IVP. It is of major importance to know the radiation dose in these procedures, especially since the examination is often repeated in the same patients. All IVP were done by means of the usual technique including possible gonad protection. The thermoluminescence dosimeter was placed rectally in the girls and fixed on the scrota in the boys. A total of 50 children was studied. Gonad dose ranged from 140 to 200mR in the girls and from 20 to 70mR in the boys (mean values). The radiation dose in IVP is very low compared to that of MCU, and from this point of view IVP is a dose saving examination in the control of children with urinary tract infections [fr

    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.

    [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.

    Full Text Available Scleroderma is progressive autoimmune disease associated with severe disability. The major underlying pathological process in scleroderma is progressive development of fibrous tissue and obliteration of the microvasculature. Currently, there are no medical products for the treatment of scleroderma that provide both sufficient immunosuppression and low-risk side safety profile with negligible side effects. There are a large number of experimental data showing that intravenous immunoglobulin (IVIG has multiple clinical and morphological effects. On the other hand, some authors report good effect of intravenous immune globulins in patients with scleroderma. The less frequent side effects of IVIG in doses below or equal to 2 g/kg/month divided in 5 consecutive days make IVIG a promising treatment of choice in scleroderma.

    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.

    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

    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.

    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.

    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

    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.

    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.

    Purpose: This study evaluates the dose area product, the amount of contrast media and the examination quality of the bolus chasing technique compared to the single-step technique in intravenous digital subtraction angiography. Material and Methods: 15 examinations each with bolus chasing and single-step technique were compared. The dose area product and the volume of contrast media were recorded. The examination quality was scored by two examiners. Results: With bolus chasing the volume of the administered contrast media could be decreased on average by 114 ml (43%). The difference between the dose area product of bolus chasing (722 dGy/cm 2 ) and single-step technique (1910 dGy/cm 2 ) was significant. No significant difference in examination quality was found. Conclusions: The intravenous bolus chasing technique is a practicable method. Compared to the single-step technique it allows a remarkable dose reduction and a low consumption of contrast media without restriction of examination quality. (orig.) [de

  5. Productivity

    DEFF Research Database (Denmark)

    Spring, Martin; Johnes, Geraint; Hald, Kim Sundtoft

    Productivity is increasingly critical for developed economies. It has always been important: as Paul Krugman puts it, “Productivity isn’t everything, but in the long run it is almost everything. A country’s ability to improve its standard of living over time depends almost entirely on its ability...... to raise its output per worker”(Krugman, 1994). Analyses of productivity have, by and large, been the preserve of economists. Operations Management (OM) is rooted in a similar concern for the efficient use of scarce resources; Management Accounting (MA) is concerned with the institutionalised measurement...... and management of productivity. Yet the three perspectives are rarely connected. This paper is a sketch of a literature review seeking to identify, contrast and reconcile these three perspectives. In so doing, it aims to strengthen the connections between policy and managerial analyses of productivity....

    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

    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 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.

    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

    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 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

    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.

    Oral uptake of lycopene has been shown to be beneficial for preventing myocardial ischemia-reperfusion (I/R) injury. However, the strong first-pass metabolism of lycopene influences its bioavailability and impedes its clinic application. In this study, we determined an intravenous (IV) administration dose of lycopene protects against myocardial infarction (MI) in a mouse model, and investigated the effects of acute lycopene administration on reactive oxygen species (ROS) production and related signaling pathways during myocardial I/R. In this study, we established both in vitro hypoxia/reoxygenation (H/R) cell model and in vivo regional myocardial I/R mouse model by ligating left anterior artery descending. TTC dual staining was used to assess I/R induced MI in the absence and presence of acute lycopene administration via tail vein injection. Lycopene treatment (1 μM) before reoxygenation significantly reduced cardiomyocyte death induced by H/R. Intravenous administration of lycopene to achieve 1 μM concentration in circulating blood significantly suppressed MI, ROS production, and JNK phosphorylation in the cardiac tissue of mice during in vivo regional I/R. Elevating circulating lycopene to 1 μM via IV injection protects against myocardial I/R injury through inhibition of ROS accumulation and consequent inflammation in mice.

    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

    To obtain imaging effects close to those of abdominal aortography and investigate a technique with little invasion to patients, intravenous aortography was applied to contrast enhancement (CE) in abdominal CT, and its usefulness was discussed. Intravenous aortography could clearly visualize lesions with rich neovascularity such as hepatocellular carcinoma and renal cell carcinoma. Differing from a drip infusion method, this method has complexities in its technique that contrast medium is injected at once, blood circulation time which is represented by the time between the injection and the time when the patients feel bitterness (10 - 12 seconds) must be measured before CE, and scanning begins 2 seconds before the patients feel bitterness. However, the invasion to patients due to this method is slight, and the capacity of this method to visualize neovascularity is superior to CE by a drip infusion method. Therefore, qualitative diagnosis by CT will be improved by using this method together with a drip infusion method.

    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.

    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.

    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.

  1. Influence of intravenous opioid dose on postoperative ileus.

    2011-07-01

    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.

    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.

    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.

    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

    Abstract Intravenous administration of lipopolysaccharide (LPS) from Escherichia coli O127:B8 at a dose of 1,500,000 units/kg BW evoked a hypothermic response followed by a fever phase in five week old broiler chickens. The hypothermic phase coincided with a severe decrease in blood pressure. We assume that this decrease in blood pressure is, at least partly, responsible for the hypothermic phase of the body temperature curve. LPS administration also caused a decrease in circulatin...

    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.

    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.

    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.

    Objective: The aim of this research was to investigate the in vivo distribution of cytokine induced killer (CIK) cell after intravenous injection in animals. Methods: CIK cell was labeled with 99 Tc m . Forty mice were equally divided into 8 groups. These mice were killed at 3, 15, 30 min and 1,3,6, 24, 48 h after intravenous 99 Tc m -CIK cell injection. The radioactivity of blood, heart, lung, liver, spleen, kidney, brain, bone and muscle were measured. Three New Zealand rabbits were scanned by dynamic SPECT imaging after intravenous injection of 37 MBq 99 Tc m -CIK cell. Serial images over whole body were acquired from immediately after injection to 48 h later. Results: The radiochemical purity of 99 Tc m -CIK cell was over 95% and remained stable within 6 h at room temperature. The clearance of 99 Tc m -CIK cell in blood was fast. High uptake of 99 Tc m -CIK cell was noted in lung, liver, spleen and kidney. Little uptake was found in heart, brain, bone and muscle. Dynamic SPECT imaging showed that 99 Tc m -CIK cell accumulated in lungs early after injection and cleared thereafter. Then the uptake in liver increased and remained there after 2 d. There was little uptake in heart, brain, bone and muscle. Conclusions: 99 Tc m -CIK cell clears fast in the blood after injection. Within 1 h, the tracer mainly accumulates in lungs. Then the uptake is mostly in liver and spleen. (authors)

    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.

    In the experiment the white outbred rats with transplanted liver cancer (cholangiocarcinoma line PC-1) and simulated alloxan diabetes were treated by single intravenous injection of gold nanorods. State of lipid peroxidation was evaluated by the following parameters: the malondialdehyde, lipid hydroperoxide, the average weght molecules in the serum of animals by conventional spectrophotometric methods study using a spectrofluorometer RF-5301 PC (Shimadzu, Japan). In both experimental groups of animals the significant increasing of levels of lipid peroxidation products was noted compared with control group. After intravenous administration of nanoparticles in the group of animals with alloxan diabetes the activation of a free radical oxidation was not observed, in group with transplanted liver cancer the increasing of levels of lipid hydroperoxide, malondialdehyde was established.

    Pain associated with castration in cattle is an animal welfare concern in beef production. This study examined the effect of oral aspirin and intravenous (i.v.) sodium salicylate on acute plasma cortisol response following surgical castration. Twenty bulls, randomly assigned to the following groups, (i) uncastrated, untreated controls, (ii) castrated, untreated controls, (iii) 50 mg/kg sodium salicylate i.v. precastration and (iv) 50 mg/kg aspirin (acetylsalicylic acid) per os precastration, were blood sampled at 3, 10, 20, 30, 40, 50 min and 1, 1.5, 2, 4, 6, 8, 10 and 12 h postcastration. Samples were analyzed by competitive chemiluminescent immunoassay and fluorescence polarization immunoassay for cortisol and salicylate, respectively. Data were analyzed using noncompartmental analysis, a simple cosine model, anova and t-tests. Intravenous salicylate V(d(ss)) was 0.18 L/kg, Cl(B) was 3.36 mL/min/kg and t(1/2 lambda) was 0.63 h. Plasma salicylate concentrations above 25 microg/mL coincided with significant attenuation in peak cortisol concentrations (P = 0.029). Peak salicylate concentrations following oral aspirin administration was castrated groups was significantly higher than uncastrated controls (P = 0.018). These findings have implications for designing drug regimens to provide analgesia during routine animal husbandry procedures.

Pharmacokinetics, biodistribution, antitumor efficacy and drug safety assessment (including acute toxicity, subchronic toxicity, hemolysis testing, intravenous stimulation and injection anaphylaxis) of NLM were carried out in comparison with the commercial product disodium norcantharidate injection (NI). The pharmacokinetics of NLM in rats was similar to that of NI, and a non-linear correlation was observed between AUC and dose. A comparable antitumor efficacy of NLM and NI was observed in mice inoculated with A549, BEL7402 and BCAP-37 cell lines. It was worth noting that the NLM produced a lower drug concentration in heart compared with NI, and significantly reduced the cardiac and renal toxicity. The LD(50) of NLM was twice higher than that of NI. In NLM, over 80% of NCTD was loaded in the lipid phase or bound with phospholipids. Thus, NCTD was sequestered by direct contacting with body fluids and largely avoided distribution into tissues, consequently leading to significantly reduced cardiac and renal toxicity. These preclinical results suggested that NLM could be a useful potential carrier for parenteral administration of NCTD, while providing a superior safety profile.

    Full Text Available AIM To compare the haemodynamic response to laryngoscopy and intubation with intravenous MgSO4 and intravenous fentanyl. METHODS Fifty adult patients were divided into two groups randomly into group M and group F. Patients of group M received 30 mg/kg body weight of IV MgSO4 and group F received IV fentanyl 1.5 µg/kg 5 minutes before intubation. RESULTS IV Fentanyl showed greater degree of haemodynamic stability i.e. rise in heart rate, mean arterial pressure during laryngoscopy and intubation compared to IV MgSO4. IV fentanyl showed side effects like respiratory depression, nausea and vomiting. CONCLUSION IV fentanyl is a better drug in controlling haemodynamic response to laryngoscopy and intubation.

    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.

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

    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.

    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.

    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.

    This study was designed to improve the clinical feasibility of intradermal skin testing of psittacine birds using intravenous fluorescein stain. Twenty-five healthy, anaesthetized Hispaniolan Amazon parrots (Amazona ventralis) were injected intravenously with 10 mg kg-1 fluorescein-sodium 1% followed by intradermal injections of 0.02 mL phosphate-buffered saline, histamine phosphate (1:100,000 w/v) and codeine phosphate (1:100,000 w/v) at the sternal apteria. Wheal diameters of reaction sites were measured grossly and under illumination with a Wood's lamp after 5 and 10 min. Fluorescence-enhanced injection sites were scored between 0 and 2, with 0 equivalent to normal skin and 2 equivalent to a plucked feather follicle. The presence of a fluorescent halo around intradermal injections was also recorded. Under Wood's light illumination at 10 min, histamine and saline were evaluated as positive and negative controls, respectively, based on a positive test having a halo and a score of 2. Sensitivity and specificity were each 76% for halo, 84 and 42% for score and 64 and 77% for combination of score and halo, respectively. Further, mean histamine reactions were significantly larger than codeine phosphate and saline (8.8 +/- 0.4 mm; 7.2 +/- 0.3 mm; 5.9 +/- 0.6 mm); however, this finding was not consistent in individual birds. Wheal size, halo presence and score were affected by site location independent from the injected compound. Intravenous fluorescein improved the readability of avian skin tests; however, the compounds tested raised inconsistent reactions in wheal size, score or halo presence. The compound-independent site effect raises concern on the validity of avian skin testing and warrants investigation of other techniques such as in vitro allergy testing. Based on our findings, intradermal allergy testing in psittacines with or without fluorescein is unreliable and cannot be recommended for practical clinical use.

    Retrospectively study.The purpose of this study was to compare the effects of intraoperative epidural steroids and single dose intravenous steroids following a percutaneous endoscopic lumbar discectomy (PELD).Inflammatory irritation of dorsal root ganglia or sensory nerve roots may cause postoperative pain. Epidural steroids have been applied after a lumbar discectomy for more than 20 years. Epidural steroid application after a PELD is easier to perform and safer because the operations are under observation of the scope.We retrospectively reviewed the medical records of patients with lumbar intervertebral disc herniation who had undergone transforaminal PELD at our department. There are 60 patients in epidural steroid group, intravenous steroid group, and control group, respectively. Visual analog scores (VAS) and the Oswestry Disability Index (ODI) were collected. Successful pain control is defined as 50% or more reduction in back and leg pain (VAS scores).VAS scores (back and leg) and ODI showed a significant decrease in all groups when comparing pre- and postoperatively. Epidural steroid group had a significant improvement in successful pain control compared with the control group at 2 weeks of follow-up. VAS scores (leg) in the epidural steroid group showed a significant decrease compared with the intravenous steroids group at 1, 3, and 7 days after the surgery, but this difference had no statistical significance at 1, 6, and 12 months of follow-up. All groups did not show a significant difference in ODI at 1, 6, and 12 months follow-up.Epidural application of steroid has a better effect on controlling the postoperative pain of PELD in the short term. The epidural application of steroid did not show a tendency to cause infection.

    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.

    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.

    Full Text Available BACKGROUND: With a wide range of applications, titanium dioxide (TiO₂ nanoparticles (NPs are manufactured worldwide in large quantities. Recently, in the field of nanomedicine, intravenous injection of TiO₂ nanoparticulate carriers directly into the bloodstream has raised public concerns on their toxicity to humans. METHODS: In this study, mice were injected intravenously with a single dose of TiO₂ NPs at varying dose levels (0, 140, 300, 645, or 1387 mg/kg. Animal mortality, blood biochemistry, hematology, genotoxicity and histopathology were investigated 14 days after treatment. RESULTS: Death of mice in the highest dose (1387 mg/kg group was observed at day two after TiO₂ NPs injection. At day 7, acute toxicity symptoms, such as decreased physical activity and decreased intake of food and water, were observed in the highest dose group. Hematological analysis and the micronucleus test showed no significant acute hematological or genetic toxicity except an increase in the white blood cell (WBC count among mice 645 mg/kg dose group. However, the spleen of the mice showed significantly higher tissue weight/body weight (BW coefficients, and lower liver and kidney coefficients in the TiO₂ NPs treated mice compared to control. The biochemical parameters and histological tissue sections indicated that TiO₂ NPs treatment could induce different degrees of damage in the brain, lung, spleen, liver and kidneys. However, no pathological effects were observed in the heart in TiO₂ NPs treated mice. CONCLUSIONS: Intravenous injection of TiO₂ NPs at high doses in mice could cause acute toxicity effects in the brain, lung, spleen, liver, and kidney. No significant hematological or genetic toxicity was observed.

    A case of spongiform leucoencephalopathy in a known intravenous heroin abuser is presented. To our knowledge, this is the only case of heroin-related spongiform leucoencephalopathy reported in Australia. The relationship to intravenous rather than inhaled heroin is particularly unusual with only one other possible case documented in the literature. The imaging and histopathological findings are described. Neurological examination revealed disorientation in time and place, memory loss and cognitive impairment but no focal signs. Biochemical and haematological profiles were normal. Viral serology was positive for hepatitis C but negative for hepatitis B and human immunodeficiency virus (HIV). Cerebral CT revealed diffuse symmetrical hypodensity of the cerebral white matter. The ventricles and subarachnoid spaces were of normal size. Magnetic resonance imaging showed diffuse symmetrical signal abnormality in the cerebral white matter. These changes were hyperintense on proton density, T2-weighted, modified T2-weighted (FLAIR) and diffusion-weighted images. T1 -weighted scans showed corresponding hypointensity. There was no enhancement after intravenous gadolinium. Cerebral spinal fluid (CSF) specimens were negative for a variety of virological, immunological and bacteriological markers. No viral or bacterial growth was demonstrated. Oligoclonal bands for multiple sclerosis and Protein 134 for Wilson's disease were negative. Right frontal brain biopsy showed spongiform white matter and degenerative change with prominent fibrous gliosis. In severely affected areas, loss of normal myelin staining and axonal loss were present, accompanied by scattered foamy macrophages. Loss of oligodendroglial nuclei was also present. There was no evidence of inflammation or progressive multifocal leucoencephalopathy. No bacteria or virus particles were seen on electron microscopic examination of the brain tissue. Following the biopsy, the patient discharged himself from hospital and the

    Full Text Available Mepivacaine is a potent local anaesthetic and used for infiltration and regional anaesthesia in adults and pediatric patients. Intoxications with mepivacaine affect mainly the CNS and the cardiovascular system. We present a case of accidental intravenous mepivacaine application and intoxication of an infant resulting in seizure, broad complex bradyarrhythmia, arterial hypotension and finally cardiac arrest. The patient could be rescued by prolonged resuscitations and a rapid initiation of ECMO and survived without neurological damage. The management strategies of this rare complication including promising other treatment options with lipid emulsions are discussed.

    In this paper we propose an inversion-based methodology for the computation of a feedforward action for the propofol intravenous administration during the induction of hypnosis in general anesthesia. In particular, the typical initial bolus is substituted with a command signal that is obtained by predefining a desired output and by applying an input-output inversion procedure. The robustness of the method has been tested by considering a set of patients with different model parameters, which is representative of a large population.

    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.

    Our large population of intravenous drug abusers has increasingly resorted to supraclavicular central venous injection for vascular access. Few reports of complications associated with the practice of supraclavicular ''pocket'' injection have appeared in the radiologic literature. The authors describe the complications associated with this practice, including pneumothorax, mycotic aneurysm, arteriovenous fistula, jugular vein thrombosis, cellulitis, foreign body reaction, and neck abscess. In addition, the authors provide examples of sternoclavicular osteomyelitis. The anatomy of the ''pocket,'' and the pathophysiology and radiographic manifestations of these complications, are reviewed

    Full Text Available Suicides by intravenous injection of an overdose of medicaments are uncommon. In this paper, we present the case of a suicide by rocuronium-bromide injection in combination with an oral overdose of metoprolol. Unfortunately, in Belgrade, there is no toxicological laboratory capable of detecting rocuronium. The interpretation of autopsy and toxicological data in this case was made difficult due to the extreme putrefaction of the body of the deceased. So, by forensic investigation, the case was solved indirectly, through circumstantial evidence: an empty ampoule of rocuronium found near the body, as well as a plastic syringe and cloth-bandage found in the left hand of the deceased.

    Dipyridamole TI-201 imaging is an ideal alternative to exercise TI-201 scintigraphy in patients who are unwilling or unable to perform maximum exercise stress. The use of intravenous dipyridamole, alone or in combination with exercise, has not been approved for clinical practice by the Food and Drug Administration. Once approval is granted, the test will become a widely used and important component of the cardiac work-up. The indications, methodology, side effects, and utility of dipyridamole cardiac imaging in the clinical setting are discussed and a variety of examples presented.59 references

    We report a screen of plasma donors confirming that widespread use of childhood measles vaccination since 1963 resulted in a decrease in average measles virus antibody titers among plasma donors, which is reflected in intravenous immunoglobulins (IVIGs). The measles virus antibody titer, however, is a potency requirement for IVIGs, as defined in a Food and Drug Administration regulation. To mitigate the decline in measles virus antibody titers in IVIGs and to ensure consistent product release, revaccination of plasma donors was investigated as a means to boost titers. However, revaccination-induced titer increases were only about 2-fold and short-lived. © The Author 2017. Published by Oxford University Press for the Infectious Diseases Society of America.

    Full Text Available Purpose: The purpose of this study was to evaluate the efficacy of tranexamic acid (TXA in reducing blood loss during surgically assisted rapid palatal expansion (SARPE procedure. Subjects and Methods: A total of 34 patients (12 male, 22 female who had been treated surgically under general anesthesia with SARPE including pterygoid disjunction for transverse maxillary deficiency (TMD were included in this study. The study group (n=17 received intravenous (IV TXA 10 mg/kg as a preoperative bolus; the control group (n=17 received normal saline solution. Preoperative and postoperative haemoglobin and haematocrit values, intraoperative blood loss, and any blood product transfusion were recorded. Results: Blood loss during SARPE was statistically significantly less in the study group than the control group (p=0.0001. Conclusion: Preoperative IV administration of TXA can effectively control blood loss during when SARPE with pterygoid disjunction is performed.

    Full Text Available Purpose: Recent studies have established the association between hypotonic fluids administration and hospital-acquired hyponatremia in children, and have contended that hypotonic fluids be removed from routine practice. To assess current intravenous fluid prescription practices among Korean pediatric residents and to call for updated clinical-practice education Methods: A survey-based analysis was carried out. Pediatric residents at six university hospitals in Korea completed a survey consisting of four questions. Each question supposed a unique scenario in which the respondents were to prescribe either a hypotonic or an isotonic fluid for the patient. Results: Ninety-one responses were collected and analyzed. In three of the four scenarios, a significant majority prescribed the hypotonic fluids (98.9%, 85.7%, and 69.2%, respectively. Notably, 69.2% of the respondents selected the hypotonic fluids for postoperative management. Almost all (96.7% selected the isotonic fluids for hydration therapy. Conclusion: In the given scenarios, the majority of Korean pediatric residents would prescribe a hypotonic fluid, except for initial hydration. The current state of pediatric fluid management, notably, heightens the risk of hospital-acquired hyponatremia. Updated clinical practice education on intravenous fluid prescription, therefore, is urgently required.

    Recent studies have established the association between hypotonic fluids administration and hospital-acquired hyponatremia in children. The present paper investigated the pattern of current practice in intravenous fluid prescription among Korean pediatric residents, to underscore the need for updated education.

In the given scenarios, the majority of Korean pediatric residents would prescribe a hypotonic fluid, except for initial hydration. The current state of pediatric fluid management, notably, heightens the risk of hospital-acquired hyponatremia. Updated clinical practice education on intravenous fluid prescription, therefore, is urgently required.

    Guidelines have been published for prevention of phlebitis associated with peripheral intravenous catheters (IVC), but this complication continues to occur. We sought to determine the rate of phlebitis associated with peripheral IVCs to identify predictors for phlebitis and to isolate pathogenic bacteria from phlebitic catheter tips. Nine-point prevalence studies were conducted during the years 1996-2003 of all hospitalized patients with a peripheral IVC. During the last 3 surveys, conducted in 2003, phlebitic lines were removed, and, for each line, 1 to 2 nonphlebitic lines, in place for 48 to 72 hours, were removed and cultured as controls. In between these surveys, findings and guidelines for improvement were distributed to the staff. During these surveys, 40% +/- 8% of hospitalized patients had a peripheral IVC. The rate of peripheral IVC-associated phlebitis decreased from 12.7% (20/157) in 1998 to 2.6% (5/189) in 2003 (P phlebitis included pain (P phlebitis associated with peripheral intravenous catheters decreased significantly throughout the study period. The identification of predictors for phlebitis and the dissemination of this information in an educational drive may have contributed to this improvement.

    To investigate potential intravenous drug incompatibilities and related risk factors in a pediatric unit. A cross-sectional analytical study conducted in the pediatric unit of a university hospital in Brazil. Data on prescriptions given to children aged 0-15 years from June to October 2014 were collected. Prescriptions that did not include intravenous drugs and prescriptions with incomplete dosage regimen or written in poor handwriting were excluded. Associations between variables and the risk of potential incompatibility were investigated using the Student's t test and ANOVA; the level of significance was set at 5% (ppenicilina G e ceftriaxona. Quase 85% das crianças apresentaram ao menos uma potencial incompatibilidade, razão de 1,2 incompatibilidades/paciente. Os tipos de incompatibilidades mais comuns foram: não testada (93,4%), precipitação (5,5%), turbidez (0,7%) e decomposição química (0,4%). Os fatores associados a potenciais incompatibilidades foram: número de medicamentos e a prescrição dos medicamentos diazepam, fenitoína, fenobarbital e metronidazol. A maioria das prescrições pediátricas apresentou potenciais incompatibilidades e a incompatibilidade não testada foi o tipo mais comum. O número de medicamentos e a prescrição dos medicamentos diazepam, fenobarbital, fenitoína e metronidazol foram fatores de risco para potenciais incompatibilidades.

  5. Intravenous digital subtraction angiography contrast media time-concentration curves

    1985-01-01

    At any specified radiation dose and system signal-to-noise ratio, temporal (masked-mode) intravenous digital subtraction angiography (IV-DSA) image quality is dependent upon the shape of the arterial time-concentration curve produced by the intravenous injection of iodinated contrast media. If contrast media appears in the arterial circulation as a compact bolus and reaches a high peak, images containing low or no iodine (the mask image or images) and high iodine concentration (the enhanced image or images) can be obtained close together in time, maximizing contrast media enhancement and minimizing the potential for spatial movement (misregistration). However, if the contrast media bolus is broad, rising slowly to a low concentration peak, sufficient time may pass for movement to occur and the opacification difference between the mask image and the enhanced image may be too small to visualize vessels of interest. Consequently, knowledge of the rules which govern the formation of time-concentration curves is central to IV-DSA

    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.

    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

    Distribution of isotopically labelled and intravenously injected cloxacillin was studied in the rabbit eye. The antibiotic concentration determined by liquid scintillation counting proved to be a reliable measure of the total antibiotic concentration when controlled by microbiological assay. In the rabbit eye after an intravenous injection of 50 mg/kg of cloxacillin sodium, longlasting antibiotic concentration regarded as therapeutic against penicillinase producing staphylococci was obtained in all vascularized ocular structures and in the cornea. The antibiotic present in the iris and ciliary body, and in the retina and choroid preparations, proved to be partly intravascular, whereas it penetrated better into the extravascular tissue compartment of the sclera and limbal area. Cloxacillin failed to achieve a therapeutic antibiotic concentration in the vitreous body and in the lens. Administration of probenecid had an enhancing effect on ocular cloxacillin concentration allowing improved drug diffusion into the eye by means of an elevated plasma concentration. No specific ocular effect of probenecid was noticed. Therapeutic concentration of cloxacillin in the aqueous humour, otherwise barely achieved, was more satisfactorily obtained with a previous injection of probenecid. (author)

    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.

    To determine the efficacy of maternal administration of intravenous amino acid solution in improving amniotic fluid volume in cases of isolated oligohydramnios and to observe its impact on mode of delivery and neonatal outcome. Study Design: A prospective case series. Methodology: Forty two women with singleton pregnancy, well established gestational age and clinically and sonographically proven isolated oligohydramnios in the third trimester before 36 weeks were administered amino acid solution intravenously after excluding cases of premature rupture of membranes, congenital anomaly of fetus, maternal pulmonary, cardiovascular and hypertensive disorders, and severe placental insufficiency (raised S/D ratio). Pre-infusion and postinfusion Amniotic fluid Index (AFI) was measured and repeated weekly. Women were followed till delivery. Results: According to repeated measurement analysis of variance, mean pre-infusion AFI was 4.7 cm, mean one week postinfusion AFI was 5.8 cm, mean two week post-infusion AFI was 6.2 cm and mean three week AFI was 6.3 cm (p-value 0.029, significant). Cesarean section became a predominant mode of delivery in this group without a firm evidence of associated fetal compromise. Conclusion: Amino acid infusion is an effective therapy for raising AFI in isolated oligohydramnios in this case series. Liberal use of cesarean section in this selected group should be carefully re-evaluated. (author)

    Full Text Available Patients with end-stage renal failure (ESRF on maintenance dialysis, commonly develop secondary hyperparathyroidism and renal osteodystrophy (ROD. Alfacalcidol, taken orally or administered intravenously, is known to reverse these complications. In this study, 19 ESRF patients, who were on dialysis (13 on hemodialysis and six on peritoneal dialysis for longer than six months and having serum parathormone levels at least four times normal and serum calcium less than 2.1 mmol/L, were randomly allocated to treatment with oral or intravenous (i.v. alfacalcidol for a period of 12 months. There were six patients on hemodialysis (HD and three on peritoneal dialysis (PD in the oral treatment group while in the i.v. group there were seven patients on HD and three on PD. Clinical and serial biochemical assessments showed no statistically significant difference between the orally- and i.v.-treated patients in terms of suppressing secondary hyperparathyroidism and osteodystrophy. However, patients with features of mild ROD on bone histology, had more satisfactory changes in biochemistry when compared to others. Our results further support the use of intermittent oral alfacalcidol in ESRF patients because of its cost effectiveness, ease of administration and convenience, especially for peritoneal dialysis patients.

    Full Text Available Background: Despite the advances in the design and fixation of implants in total knee replacement (TKR. the amount of postoperative bleeding is still an important issue that has not been resolved. This study aimed to measure the effectiveness of various tranexamic acid administration.Methods: This was a randomized controlled trial study, held from August 2014 to February 2016 at Cipto Mangunkusumo Hospital, Jakarta. Twenty two patients having TKR were divided into three groups: the control group, the tranexamic acid intra-articular-intraoperative group, and the intravenous preoperative group. Intraoperative bleeding, haemoglobin (Hb level on preoperative to five-day-post-surgery, total drain production, total blood tranfusion needed and the drain removal timing were recorded and compared. Numerical data were analyzed by using parametric and non-parametric test, depended on the normality of the data.Results: The amount of blood transfusion needed in both the intra-articular group (200±SD 100 mL and the intravenous group (238±SD 53 mL were significantly different compared to those in the control group (1,016±SD 308.2 mL (p=0.001. Meanwhile, there was no significant difference between the amount of blood transfusion needed in the intra-articular group and the intravenous group. Total drain production in the intra-articular group (328±SD 193 mL and intravenous group (391±SD 185 mL was significantly different compared to the control group (652±SD 150 mL (p=0.003. No significant difference between the levels of both preoperative and postoperative haemoglobin, the amount of intraoperative bleeding, and the duration of drain usage.Conclusion: Intravenous and intra-articular tranexamic acid effectively decreased transfusion volume and drain production in patients undergoing TKR.

    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.

    Two urographic methods were compared: the intravenous urographic bolus (i.u.b.) and the intravenous urographic infusion (i.u.i.). In both methods, two groups of seven healthy adult dogs of both sexes, weighing7.0 to 16.5 kg were used and were anaesthesized with 2% thiopentone sodium in doses of 20 mg/kg via cephalica. In the i.u.b., meglumine diatrizoate (Hypaque-M, 60%) was injected via saphena with a concentration of 282 mg of iodine per mi in doses of 564 mg of iodine per kg. In the i.u.i., meglumine diatrizoate was injected via saphena by drip infusion with a concentration of 200 mg of iodine per mi in doses of 500 mg of iodine per kg. Three series of two X-rays each were taken in ventrodorsal projection 1, 4 and 8 min and left lateral recumbency 30 sec after administering the contrast medium. The X-ray plates obtained were analyzed and compared intra and inter group considering the advance speed of the contrast medium, the radiographic density and outline, and kidney size. The advance speed of the contrast medium was higher in the i.u.i., reaching the kidney, ureter and bladder 1 min after administration in both projections; in ventrodorsal projections in the i.u.b. only the kidneys were reached while in the left lateral recumbency, the kidney and ureters were reached [es

    • BACKGROUND: Hepatitis C (HCV is increasing worldwide including Iran. HCV is more prevalent among intravenous drug abusers (IDU, especially if imprisoned, mostly due to needle sharing. We determined the rate of HCV seropositivity among IDU prisoners and compared it with those of non-prisoners.
    • METHODS: A cross-sectional study was conducted on consenting IDUs inhabiting two prisons and attending three rehabilitation centers in Tehran, Iran. A questionnaire was completed for each subject and 5 ml blood was drawn. The samples were kept at 2-8°C until the sera were separated and stored at -70°C. HCVAb (ELISA was checked by a single technician. Chi-square, Fisher's exact test and multivariate analysis were used where appropriate.
    • RESULTS: Five-hundred and eighteen subjects were enrolled. About 74.5% were prisoners and 89.6% were male. Overall, 59.5% were positive for HCVAb (93.2% males and 6.8% females, P < 0.02. HCV seropositivity was higher among prisoners compared to non-prisoners (78.3% vs. 30.6%, respectively, P < 0.001. Also, it was higher in IUD older than 45 year-old compared to those younger than 30 year-old (77.8% vs.54.2%, respectively, P = 0.002. Multivariate analysis showed significant association of HCV seropositivity with imprisonment (OR: 9.32, 95% CI: 5.60-15.51, sharing syringes (OR: 2.00, 95% CI: 1.26-3.17 and duration of intravenous drug use (OR: 0.86, 95% CI: 0.80-0.92.
    • CONCLUSIONS: HCV is rather common among IDU prisoners. Imprisonment is an independent risk factor for HCV and the infected IDUs going back to the society could be an important source of HCV. Taking effective strategies (education of high risk groups, provision of sterile syringes, identification and treatment of infected IDUs to reduce the risk of this public health problem is needed urgently.

    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.)

    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.

    Intravenous access for blood sampling or drug administration that requires peripheral venepuncture is perhaps the most common invasive procedure practiced in hospitals, clinics and general practice surgeries.We describe an idealised mathematical framework for modelling the dynamics of the peripheral venepuncture process. Basic assumptions of the model are confirmed through motion analysis of needle trajectories during venepuncture, taken from video recordings of a skilled practitioner injecting into a practice kit. The framework is also applied to the design and construction of a proposed device for accurate needle guidance during venepuncture administration, assessed as consistent and repeatable in application and does not lead to over puncture. The study provides insights into the ubiquitous peripheral venepuncture process and may contribute to applications in training and in the design of new devices, including for use in robotic automation.

    Full Text Available Objective . We present the clinical, biochemical, and imaging findings of a woman with vitamin D deficiency and severe osteomalacia related to intravenous heroin addiction. Results . A 54-year-old woman with a medical history significant for long-standing heroin abuse presented with complaints of bone pain, muscle cramping, and a left hip ulcer. She had been bed bound for approximately 1 year secondary to pain of uncertain etiology, and her husband was bringing her both food and drugs. She was admitted to the hospital for debridement of a right ischial ulcer. Further workup revealed osteomyelitis of the left hip and severe vitamin D deficiency. Radiologic evaluation demonstrated diffuse osteopenia with pseudofractures, as well as true fractures. Conclusion . This is the first case reported in the English literature of advanced osteomalacia resulting from a debilitating narcotic dependency. Vitamin D deficiency should be considered in patients with poor nutrition and prolonged sunlight deprivation from any cause.

    In order to assess the accuracy of intravenous digital subtraction angiography (IV-DSA), the authors prospectively studied all patients referred for suspected renovascular hypertension with IV-DSA and conventional angiography. The IV-DSA study demonstrated renal artery stenosis in 25 patients. A significant main renal artery lesion was confirmed in 21 of these patients while four patients had either normal renal arteries or insignificant changes. The IV-DSA examination was considered negative for renal artery stenosis in 50 patients. This was confirmed in 49 patients, but one patient had a branch renal artery stenosis. The sensitivity of IV-DSA was 96% while the specificity was 93%. The negative predictive value was 98% and the positive predictive value 84%. IV-DSA provides good anatomic definition of the main renal arteries and is sufficiently sensitive to be used as a screening test for renovascular hypertension

    This invention relates to digital intravenous subtraction angiography (DISA), and more particularly concerns novel apparatus and techniques for providing high resolution angiograms with equipment that coacts with existing standard medical X-ray equipment. A typical medical X-ray generator provides low mA, continuous X-ray exposures illuminating a standard image intensifier producing an image scanned by a conventional television camera to produce a video signal. An analog-to-digital converter digitizes the signal, and adding means adds the digital frame signals together in real time to provide an intermediate digital signal representing the addition of 5 to 20 frames. Digital storage means store the intermediate image signals. Preferably there are two system memories with means for summing a subsequent intermediate image in the second memory while a previously-formed intermediate image is being transferred to disk storage

    A total of 29 peafowl (Pavo cristatus), rectified surgically for infraorbital abscesses (n = 22), lacerated wounds (n = 4), and fractures of tibia (n = 2) and radius (n = 1), were anaesthetized by the intravenous administration of ketamine hydrochloride (Inj. Calypsol, Gedeon Richter, Hungary) in a dose of 15 20 mg/kg body weight. Divided doses (10 mg + 5 mg + 5 mg) were used with an interval of 1-2 min. No premedication was undertaken in any of the birds. Anaesthesia lasted for about 15 min and the birds gained their feet completely after 30 min to 3 hours. The respiration rate was markedly depressed (8-10/min) and the respiratory pattern was deep abdominal. Only a slight increase was observed in the heart rate. Analgesia was incomplete and muscle relaxation was not satisfactory. Mild salivation was also noticed in some of the birds (n = 3). Recovery, although not smooth, was uneventful.

    Full Text Available This study aimed at identifying scientific publication on phlebitis caused by amiodarone and proposes a nursing care algorithm for interventions in intravenous amiodarone administration grounded in the Infusion Nursing Society and the Center for Disease Control and Prevention. It is a descriptive study mediated by integrative review in MedLine, LILACS, IBECS, BDENF, Cochrane Library and Scielo bases, published from 2006 to 2013. The sample consisted of nine articles. The evidence pointed the incidence of phlebitis due to the infusion of amiodarone and the need to control this event. The algorithm proposed shows the materials to be used and the procedure of drug administration in order to minimize injury. Besides subsidizing the development of future studies, this algorithm also promotes the incorporation of the best recommendation for the interventionist clinical practice.

    A classification has been made of various types of stratification phenomenon during intravenous cholangiography. The stage of gallbladder opacification in the recumbent position has been classified as (I) mottled, (II) dendritic, (III) ring-like, and (IV) homogeneous. 'Dendritic' type of stratification phenomenon has never been reported in the literature to our knowledge. At 20 min following infusion of contrast material homogeneous opacification of the gallbladder was noticed in only 14% of patients. The others fell into types I, II or III of stratification phenomenon. In contrast, 87% of the opacified gallbladders were homogeneous on the after fatty meal film. It is therefore mandatory for diagnosis that either a 24 h film or a fatty meal film be taken to avoid the stratification phenomenon.

  11. 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.

    Radiocontrast media-induced acute severe thrombocytopenia is a very rare complication and potentially life-threatening. Here, we report the case of a 63-year-old male patient with severe acute thrombocytopenia following first exposure to intravenous non-ionic contrast media without immediate allergic reactions. His platelet count dropped from 107000/μL to 2000/μL after six hours of radiocontrast infusion. After administration of corticosteroid and transfusion of platelet concentrates, the platelet count returned gradually to normal within 5 days. To the best of our knowledge, non-ionic contrast media-induced isolated acute severe thrombocytopenia following no signs or symptoms of immediate allergic reaction has never been described. © Copyright: Yonsei University College of Medicine 2018.

    Parkinsonism due to multiple sclerosis (MS) is rare. In previously reported patients with MS-induced parkinsonism, MS manifested first, followed a typical clinical course, and parkinsonism developed later in the course of the illness. We report a 52-year-old male presenting with parkinsonism as the initial manifestation of MS, in whom a subsequent MS relapse consisted of marked deterioration in parkinsonism, a clinical pattern not previously described in MS. A brain MRI demonstrated involvement of the substantia nigra and basal ganglia. This patient illustrates that the clinical presentation and progression of MS may rarely be characterised by predominating parkinsonian features which are reversible by treatment with intravenous methylprednisolone and interferon beta1a.

    2012-12-01

    Full Text Available Intravenous (IV Paracetamol is an excellent post operative analgesic and antipyretic in children. Efficacy and tolerability of IV Propacetamol have been established in pediatric practice. It is believed that paracetamol works by inhibiting cyclooxygenase-2 (COX-2 enzymes. Studies bring to light that therapeutic doses of IV acetaminophen are effective and tolerable in children with least chances of hepatotoxicity. However, overdose toxicity has been reported in children and drug induced hypotension in febrile critically ill patients. Therapeutic doses according to body weight of neonates and children can be administered in hospital settings. Special education of health care staff regarding precise dose and solution is necessary to assess the role of IV paracetamol preparation in pediatric practice.

  16. Successful treatment of idiopathic pulmonary capillaritis with intravenous cyclophosphamide.

    2013-03-01

    Idiopathic pulmonary hemosiderosis (IPH), a subtype of diffuse alveolar hemorrhage is a rare condition, first described by Virchow in 1864. Historically, it manifests in children in the first decade of life with the combination of hemoptysis, iron deficiency anemia, and alveolar infiltrates on chest radiograph. More recently, diffuse alveolar hemorrhage has been classified by the absence or presence of pulmonary capillaritis (PC), the latter carrying a potential for a poorer outcome. While systemic corticosteroids remain the first line treatment option, other immune modulators have been trailed including hydroxychloroquine, azathioprine, 6-mercaptopurine, and cyclophosphamide with varying results. Our case demonstrates for the first time, the successful use of intravenous cyclophosphamide in the management of chronic idiopathic PC.

  17. Advice on the management of reactions to intravenous contrast media

    International Nuclear Information System (INIS)

    1996-01-01

    The College has previously issued guidelines for the management of adverse reactions to intravenous ionic and non-ionic contrast media. The following updated guidelines are applicable to both children and adults. The reported adverse reaction rate to conventional ionic contrast media is about 5%, the vast majority of reactions being of a minor nature, and to the newer non-ionic contrast media, approximately 1%. The rare serious reaction, with an estimated incidence of 0.05% with ionic contrast media and substantially less with non-ionic media, must be treated quickly and appropriately. Identification and symptomatic characterisation of the reaction are the key first steps and should be followed by ad hoc management based on general principles. (author)

    In this study radiation doses in IVU clinical examinations were measured in three public hospitals and a sample of 44 patients. In each room the machine output was measured for different peak tube voltages. Patient's data such as (age and weight) and exposure parameters (kVp) and mAs) were recorded. Entrance Surface Air Kerma (ESAK) for patients was determined by using the tube output and the patient exposure parameters. The ESAK ranged from 0.76 to 6.75 mGy. The cumulative ESAK ranged from 3.5 to 34.6 mGy. In conclusion, the obtained results are in agreement with the standard reference ESAK levels. The study showed that the cumulative ESAK can approach a level known to increase the probability of stochastic effect. Keywords: Patient dose, intravenous Urography, radiation protection

    1987-01-01

    To determine the relevance of allergy as a predisposing factor in reactions to radiographic contrast media, the authors investigated the incidence of allergy among 100 randomly selected patients undergoing intravenous excretory urography and CT. The study population consisted of 50 reactors and 50 nonreactos to radiographic contrast media. All 100 subjects completed an allergy history, percutaneous allergy tests, and an in vitro specific IgE assay to common allergens. Thirty-four of 50 reactors had a positive allergy history, in contrast to 15 of 50 nonreactors (P < .001). Twenty-seven reactors had positive skin tests, in contrast to 12 of 50 nonreactors (P < .005). In vitro IgE assay results are pending. The results indicate that patients with positive histories or positive skin tests or both are at an increased risk for reactions to radiographic contrast media

In this study, organic nanotubes (ONTs with a carboxyl group at the surface, a length of approximately 2 µm and outer diameter of 70–90 nm, were injected intravenously into tumor-bearing mice. To use ONTs as drug carriers, the biodistribution in selected organs of ONTs postinjection was examined using irinotecan, as an entrapped water-soluble marker inside ONTs, and gadolinium-chelated ONT, as an ONT marker, and compared with that of a 3 µm fluorescently labeled spherical microparticle which was similar size to the length of ONTs. It was found that for irinotecan, its active metabolite and gadolinium-chelated ONTs were highly accumulated in the lung, but to a lower level in the liver and spleen. On the other hand, microparticles deposited less in the lung and more highly in the liver. Moreover, histologic examination showed ONTs distributed more in lung tissues in part, whereas microparticles were present in blood vessels postinjection. These preliminary results support the notion of using negatively charged ONTs as intravascular carriers to maximize accumulation in the lung whilst reducing sequestration by the liver and spleen. This finding suggested that ONTs are potential carriers for lung-targeting drug delivery.Keywords: organic nanotube, lung, biodistribution, microparticle, particle shape

    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.

    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 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

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.

    Levetiracetam is a commonly used antiepileptic medication for tumor-related epilepsy. However, the 100 mL intravenous (IV) infusion volume can be burdensome to imminently dying hospice patients. A reduced infusion volume would improve patient tolerability. The purpose of this study was to evaluate the stability of 1000 mg/25 mL (40 mg/mL) levetiracetam IV solution in sodium chloride 0.9%. We prepared levetiracetam 40 mg/mL IV solution and added it to polyvinyl chloride (PVC) bags, polyolefin bags, and polypropylene syringes. Triplicate samples of each product were stored at refrigeration (2-8°C) and analyzed on days 0, 1, 4, 7, and 14. Samples were subjected to visual inspection, pH measurement, and stability-indicating high-performance liquid chromatography (HPLC) analysis. Over the 2-week storage period, there was no significant change in visual appearance or pH for any of the stability samples. The HPLC results confirmed that all stability samples retained 94.2-101.3% of initial drug concentration and no degradation products or leachable material from the packaging materials were observed. We conclude that levetiracetam 1000 mg/25 mL IV solution in sodium chloride 0.9% is physically and chemically stable for up to 14 days under refrigeration in polypropylene syringes, PVC bags, and polyolefin bags.

    Peripheral intravenous (PIV) infiltrations causing tissue damage is a global issue surrounded by situations that make vascular access decisions difficult. The purpose of this quality improvement project was to develop an algorithm and assess its effectiveness in reducing PIV infiltrations in neonates. The targeted subjects were all infants in our neonatal intensive care unit (NICU) with a PIV catheter. We completed a retrospective chart review of the electronic medical record to collect 4th quarter 2012 baseline data. Following adoption of the algorithm, we also performed a daily manual count of all PIV catheters in the 1st and 2nd quarters 2013. Daily PIV days were defined as follows: 1 patient with a PIV catheter equals 1 PIV day. An infant with 2 PIV catheters in place was counted as 2 PIV days. Our rate of infiltration or tissue damage was determined by counting the number of events and dividing by the number of PIV days. The rate of infiltration or tissue damage was reported as the number of events per 100 PIV days. The number of infiltrations and PIV catheters was collected from the electronic medical record and also verified manually by daily assessment after adoption of the algorithm. To reduce the rate of PIV infiltrations leading to grade 4 infiltration and tissue damage by at least 30% in the NICU population. Incidence of PIV infiltrations/100 catheter days. The baseline rate for total infiltrations increased slightly from 5.4 to 5.68/100 PIV days (P = .397) for the NICU. We attributed this increase to heightened awareness and better reporting. Grade 4 infiltrations decreased from 2.8 to 0.83/100 PIV catheter days (P = .00021) after the algorithm was implemented. Tissue damage also decreased from 0.68 to 0.3/100 PIV days (P = .11). Statistical analysis used the Fisher exact test and reported as statistically significant at P < .05. Our findings suggest that utilization of our standardized decision pathway was instrumental in providing guidance for

    Alcohol consumption produces a complex array of effects that can be divided into two types: the explicit pharmacological effects of ethanol (which can be temporally separate from time of intake) and the more temporally "relevant" effects (primarily olfactory and taste) that bridge the time from intake to onset of the pharmacological effects. Intravenous (IV) self-administration of ethanol limits the confounding "non-pharmacological" effects associated with oral consumption, allows for controlled and precise dosing, and bypasses first order absorption kinetics, allowing for more direct and better-controlled assessment of alcohol's effect on the brain. IV ethanol self-administration has been reliably demonstrated in mouse and human experimental models; however, models of IV self-administration have been historically problematic in the rat. An operant multiple-schedule study design was used to elucidate the role of each component of a compound IV-ethanol plus oral-sucrose reinforcer. Male alcohol-preferring P rats had free access to both food and water during all IV self-administration sessions. Animals were trained to press a lever for orally delivered 1% sucrose (1S) on a fixed ratio 4 schedule, and then surgically implanted with an indwelling jugular catheter. Animals were then trained to respond on a multiple FR4-FR4 schedule composed of alternating 2.5-min components across 30-min sessions. For the multiple schedule, two components were used: an oral 1S only and an oral 1S plus IV 20% ethanol (25 mg/kg/injection). Average total ethanol intake was 0.47 ± 0.04 g/kg. We found significantly higher earning of sucrose-only reinforcers and greater sucrose-lever error responding relative to the compound oral-sucrose plus IV-ethanol reinforcer. These response patterns suggest that sucrose, not ethanol, was responsible for driving overall responding. The work with a compound IV ethanol-oral sucrose reinforcer presented here suggests that the existing intravenous ethanol

    Anemia is common in Congestive Heart Failure (CHF) and is associated with an increased mortality, morbidity and progressive renal failure. The most common causes of the anemia in CHF are (1) the associated Chronic Kidney Disease (CKD), which causes depression of erythropoietin (EPO) production in the kidney, and (2) excessive cytokine production in CHF, which can cause both depression of erythropoietin production in the kidney and depression of erythropoietin response in the bone marrow. The cytokines can also induce iron deficiency by increasing hepcidin production from the liver, which both reduces gastrointestinal iron absorption and reduces iron release from iron stores located in the macrophages and hepatocytes. It appears that iron deficiency is very common in CHF and is rarely recognized or treated. The iron deficiency can cause a thrombocytosis that might contribute to cardiovascular complications in both CHF and CKD and is reversible with iron treatment. Thus, attempts to control this anemia in CHF will have to take into consideration both the use of both Erythropoiesis Stimulating Agents (ESA) such as EPO and oral and, probably more importantly, intravenous (IV) iron. Many studies of anemia in CHF with ESA and oral or IV iron and even with IV iron without ESA have shown a positive effect on hospitalization, New York Heart Association functional class, cardiac and renal function, quality of life, exercise capacity and reduced Beta Natriuretic Peptide and have not demonstrated an increase in cardiovascular damage related to the therapy. However, adequately powered long-term placebo-controlled studies of ESA and of IV iron in CHF are still needed and are currently being carried out.

    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)

    Full Text Available Objective. To quantify the degree of plasma volume expansion that occurs during an intravenous glucose tolerance test (IVGTT. Methods. Twenty healthy volunteers (mean age, 28 years underwent IVGTTs in which 0.3 g/kg of glucose 30% was injected as a bolus over 1 min. Twelve blood samples were collected over 75 min. The plasma glucose and blood hemoglobin concentrations were used to calculate the volume distribution (Vd and the clearance (CL of both the exogenous glucose and the injected fluid volume. Results. The IVGTT caused a virtually instant plasma volume expansion of 10%. The half-life of the glucose averaged 15 min and the plasma volume expansion 16 min. Correction of the fluid kinetic model for osmotic effects after injection reduced CL for the infused volume by 85%, which illustrates the strength of osmosis in allocating fluid back to the intracellular fluid space. Simulations indicated that plasma volume expansion can be reduced to 60% by increasing the injection time from 1 to 5 min and reducing the glucose load from 0.3 to 0.2 g/kg. Conclusion. A regular IVGTT induced an acute plasma volume expansion that peaked at 10% despite the fact that only 50–80 mL of fluid were administered.

    Intravenous immunoglobulin (IVIg) therapy has multiple mechanisms of immunomodulatory action. We wished therefore to assess its efficacy in a spectrum of patients with refractory uveitis. Retrospective review of clinical charts was conducted to document response to IVIg treatment in consecutive patients with treatment-refractory uveitis. Main outcome measures were control of intraocular inflammation, visual acuity, progression of the disease, and complications. Four (two male) patients, with a mean age at the beginning of the treatment of 47 years (range: 39-64), were included in the study. Indication for treatment was patients with active non-infectious uveitis refractory to steroids and immunomodulatory therapy. All patients received a course of 0.5 g/kg per day of IVIg for three consecutive days, repeating this course at a mean of 11 week (range: 2-39 weeks) intervals when indicated clinically. The median duration of the IVIg therapy was 7 months (range: 3-14 months). In three patients treatment resulted in stabilisation and prevention of progression of the disease, and additionally in two patients it facilitated a decrease in prednisolone dose. Treatment failed to induce long-term remission in one patient with recurrence of macular oedema. IVIg was well tolerated with neither immediate nor longer-term adverse events observed. In three out of four cases IVIg was an effective adjunctive therapy and well tolerated for the management of treatment-refractory uveitis.

    Full Text Available Influenza is a highly contagious, acute, febrile respiratory infection that can have fatal consequences particularly in individuals with chronic illnesses. Sporadic reports suggest that intravenous immunoglobulin (IVIg may be efficacious in the influenza setting. We investigated the potential of human IVIg to ameliorate influenza infection in ferrets exposed to either the pandemic H1N1/09 virus (pH1N1 or highly pathogenic avian influenza (H5N1. IVIg administered at the time of influenza virus exposure led to a significant reduction in lung viral load following pH1N1 challenge. In the lethal H5N1 model, the majority of animals given IVIg survived challenge in a dose dependent manner. Protection was also afforded by purified F(ab′2 but not Fc fragments derived from IVIg, supporting a specific antibody-mediated mechanism of protection. We conclude that pre-pandemic IVIg can modulate serious influenza infection-associated mortality and morbidity. IVIg could be useful prophylactically in the event of a pandemic to protect vulnerable population groups and in the critical care setting as a first stage intervention.

    Intravenous DSA (IVDSA) was evaluated as a screening method for cerebral aneurysms. It was performed 390 times in 372 cases. Clinically useful images were obtained in 94.1% in all examinations. Nineteen aneurysms were visualized in cerebral angiography among 21 cases with SAH or 3rd nerve palsy, whereas in IVDSA 15 aneurysms were noted. Aneurysms not visualized in IVDSA were all 4 mm or less in size. Therefore, aneurysms, more than 4 mm in size, which have higher risks for rupture, were detectable in IVDSA. Based on these findings, IVDSA is considered to be clinically useful in screening for aneurysms. In all 372 cases, 33 aneurysms were suspected in IVDSA findings, whereas in cerebral angiography 21 of them turned to be aneurysms. Such 12 false positive cases were distributed mainly at anterior communicating and middle cerebral arteries. Improvement of image resolution, avoidance of vessel overlapping and proper selection of screened cases should be investigated for further development of this screening method. (author)

    Peripheral intravenous catheters (PIVCs) are frequently removed due to phlebitis. We hypothesized that catheters made of polyurethane, which is more flexible than Teflon, would decrease phlebitis, and that flexibility could be estimated by measuring the catheter-tip angle. Ultrasonography in two groups of patients with different catheter types was then used to compare catheter-tip angles and phlebitis. Observational studies were carried out at a medical ward in a university hospital. Infusion therapy was administered to one group of patients in 2014 using Teflon catheters (control group, n = 200), and to another group of patients in 2015 using polyurethane catheters (investigational group, n = 207). The symptoms were assessed according to a scale developed by the Infusion Nurses Society. Long-axis ultrasonography images taken immediately before catheter removal were used to measure the angle between the central line of the catheter within 2 mm from the distal point and a tangent to the vessel wall. There were no significant differences between the two groups with respect to sex, age, and medical diagnosis. In the control and investigational groups, the rates of phlebitis were 37% (73/200) and 17% (36/207), respectively (pPhlebitis occurred more frequently when the catheter-tip was placed at angle >5.8°. The frequency of phlebitis was lower in the polyurethane, in which the catheter was placed at lower angle, almost parallel to the vessel. Our results will aid in developing new catheters and in improving PIVC-securement techniques.

    Peripheral intravenous catheter-related phlebitis is a common and significant problem in clinical practice. This study aims to investigate the incidence of phlebitis and to evaluate some important related factors. 300 patients admitted to medical and surgical wards of hospitals in Semnan, Iran from April 2003 to February 2004 were prospectively studied. Variables evaluated were age, gender, site and size of catheter, type of insertion and underlying conditions (diabetes mellitus, trauma, infectious disease and burns). Phlebitis was defined when at least four criteria were fulfilled (erythema, pain, tenderness, warmth, induration, palpable cord and swelling). Any patient who was discharged or their catheter removed before three days were excluded. Phlebitis occurred in 26 percent (95 percent confidence interval [CI] 21- 31 percent) of patients. There was no significant relationship between age, catheter bore size, trauma and phlebitis. Related risk factors were gender (odds-ratio [OR] 1.50, 95 percent CI 1.01-2.22), site (OR 3.25, 95 percent CI 2.26-4.67) and type of insertion (OR 2.04, 95 percent CI 1.36-3.05) of catheter, diabetes mellitus (OR 7.78, 95 percent CI 4.59-13.21), infectious disease (OR 6.21, 95 percent CI 4.27-9.03) and burns (OR 3.96, 95 percent CI 3.26-4.82). Phlebitis is still an important and ongoing problem in medical practice. In patients with diabetes mellitus and infectious diseases, more attention is needed.

    Full Text Available Introduction. Venous aneurysm (VA is a rare condition that can be presented in both superficial and deep venous system. Secondary VAs as well as pseudoaneurysms are usually caused by external spontaneous or iatrogenic trauma. They are often misdiagnosed and inadequately treated. Complications include thrombosis, phlebitis, eventual pulmonary embolism and rupture. Case report. We presented a case of secondary VA of the great saphenous vein developed in a young addict following chronic intravenous drug application in the groin region. Aneurysm required urgent surgical treatment due to bleeding complication as it was previously misdiagnosed for hematoma (or abscess and punctuated by a general surgeon. Complete resection of VA with successful preservation of continuity of the great saphenous vein was performed. Postoperative course was uneventful. Regular venous flow through the great saphenous vein was confirmed on control ultrasound examination. Conclusion. VAs are uncommon, among them secondary VA being extremely rare. In cases with a significant diameter or threatening complications surgical treatment is recommended. [Projekat Ministarstva nauke Republike Srbije, br. ON175008 i br. III41007

    The optimal temporal window of intravenous (IV) computed tomography (CT) cholangiography was prospectively determined. Fifteen volunteers (eight women, seven men; mean age, 38 years) underwent dynamic CT cholangiography. Two unenhanced images were acquired at the porta hepatis. Starting 5 min after initiation of IV contrast infusion (20 ml iodipamide meglumine 52%), 15 pairs of images at 5-min intervals were obtained. Attenuation of the extrahepatic bile duct (EBD) and the liver parenchyma was measured. Two readers graded visualization of the higher-order biliary branches. The first biliary opacification in the EBD occurred between 15 and 25 min (mean, 22.3 min {+-} 3.2) after initiation of the contrast agent. Biliary attenuation plateaued between the 35- and the 75-min time points. Maximum hepatic parenchymal enhancement was 18.5 HU {+-} 2.7. Twelve subjects demonstrated poor or non-visualization of higher-order biliary branches; three showed good or excellent visualization. Body weight and both biliary attenuation and visualization of the higher-order biliary branches correlated significantly (P<0.05). For peak enhancement of the biliary tree, CT cholangiography should be performed no earlier than 35 min after initiation of IV infusion. For a fixed contrast dose, superior visualization of the biliary system is achieved in subjects with lower body weight. (orig.)

    To describe successful treatment of canine moxidectin toxicosis with the novel therapy of IV lipid administration. A 16-week-old female Jack Russell Terrier was presented with acute onset of seizures followed by paralysis and coma shortly following suspected exposure to an equine formulation of moxidectin. Moxidectin toxicity was later confirmed. Initial therapy consisted of diazepam, glycopyrrolate, and IV fluids. Mechanical ventilation and supportive nursing care were provided as needed. An emulsion of 20% soybean oil in water, commonly used as the fat component of parenteral nutrition, was administered intravenously as a bolus of 2 mL/kg followed by 4 mL/kg/h for 4 hours beginning 10 hours after exposure and was administered again at a rate of 0.5 mL/kg/min for 30 minutes beginning 25.5 hours post-exposure. Mild improvement was seen after the first dose, and dramatic improvement was noted within 30 minutes of the second dose. The puppy's neurologic status returned to normal within 6 hours of the second administration, with no relapses. IV lipid therapy is a novel treatment approach for moxidectin toxicity. Its use is supported by recent research and case studies involving IV lipid administration for bupivacaine and other fat-soluble toxins. Lipid administration appeared to reverse the signs of toxicity and may prove to be a highly effective therapy for moxidectin and other fat-soluble toxins.

    Full Text Available Background: Reports on the association of nosocomial bacterial infections with indwelling medical devices such as intravenous catheters (IVC has increased in recent years. The potential to form biofilm on these devices seems to be the main reason for establishment of such infections. The aim of this study was to measure the potential of biofilm formation by bacterialisolates from IVCs.Methods: Seventy-one IVCs were collected from hospitalized patients in ICU, NICU, hematology and oncology wards at Taleghani Hospital from Jan 2010 to Jan 2011. The bacterial isolates were identified using the standard biochemical tests and the potential to form biofilms was determined by the microtiter plate assay method (MTP and colony morphology using Congo red agar plates (CRA.Results: Overall, 54 (71% IVCs were colonized and 76 bacteria were isolated among which, 64 (84.2% were coagulase negative staphylococci (CoNS, 3 (3.9% S. aureus, 3 (3.9% Enterococcus spp., 2 (2.6% E. coli and 4 (5.3% were miscellaneous isolates not further identified. Among the CoNS, biofilm formation was observed in 68.7% and 82.8% of bacteriausing MTP and CRA methods, respectively. S. aureus and E. coli isolates also were biofilm producers but Enterococcus and other unknown isolates were biofilm negative.Conclusions: Our results confirm that the prevalent biofilm forming bacteria on IVCs were CoNS and that was the reason for high rates of nosocomial infections.

    To evaluate the acute effect of intravenous caffeine on heart rate and blood pressure variability in preterm infants. We extracted and compared linear and non-linear features of heart rate and blood pressure variability at two timepoints: prior to and in the two hours following a loading dose of 10 mg/kg caffeine base. We studied 31 preterm infants with arterial blood pressure data and 25 with electrocardiogram data, and compared extracted features prior to and following caffeine administration. We observed a reduction in both scaling exponents (α 1 , α 2 ) of mean arterial pressure from detrended fluctuation analysis and an increase in the ratio of short- (SD1) and long-term (SD2) variability from Poincare analysis (SD1/SD2). Heart rate variability analyses showed a reduction in α 1 (mean (SD) of 0.92 (0.21) to 0.86 (0.21), p < 0.01), consistent with increased vagal tone. Following caffeine, beat-to-beat pulse pressure variability (SD) also increased (2.1 (0.64) to 2.5 (0.65) mmHg, p < 0.01). This study highlights potential elevation in autonomic nervous system responsiveness following caffeine administration reflected in both heart rate and blood pressure systems. The observed increase in pulse pressure variability may have implications for caffeine administration to infants with potentially impaired cerebral autoregulation.

    Full Text Available Introduction: The intraosseous (IO route has become a popular method to gain access to the peripheral circulation in emergency situations. Despite little supporting data, it is generally believed that IO absorption is immediate and equivalent to the intravenous (IV route. It is important to determine if rocuronium can effectively be administered by the IO route. The aim of the study was to determine and compare the onset and duration of rocuronium when administered via the IO and IV routes in a normovolemic pig model. Methods: We recorded electromyographic (EMG data following tibial IO and peripheral IV administration of rocuronium (1.2 mg/kg in 10 swine weighing between 56 and 71 Kg. We transformed data were transformed to percent of baseline, determined onset and recovery characteristics. Results: The onset EMG-time profiles for IO and IV administration were very similar: tibial IO compared to IV administration did not statistically alter the onset of paralysis. The IO group took statistically longer than the IV group to return to 50 (p=0.042, 75 (p=0.034 and 95 (p=0.036 percent of baseline activity. Conclusion: The duration of effect is statistically longer after IO administration but is more of an academic interest than a clinical concern. The results of this study suggest that rocuronium can effectively be administered via the IO route without the need for dose adjustments. [West J Emerg Med. 2014;15(2:241-245.

    In today’s world of automation, there are advancements going on in all the fields. Each work is being automated day by day. However, if we see our current medical care system, some areas require manual caretaker and are loaded with heavy jobs, which consumes a lot of time. Nevertheless, since the work is related to human health, it should be properly done and that too with accuracy. An example of such a particular work is injecting saline or Intravenous (IV) fluids in a patient. The monitoring of such fluids needs utter attention as if the bottle of the fluid is not changed on time, it may lead to various problems for the patients like backflow of blood, blood loss etc. Various researches have been performed to overcome such critical situation. Different monitoring and alerting techniques are described in different researches. So, in our study, we will go through the researches done in this particular field and will see how different ideas are implemented.

    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

    Full Text Available Ischemic stroke patients with active cancer are known to have poor clinical outcomes. However, the efficacy and safety of intravenous alteplase (IV t-PA in this group are still unclear. In this study, we aimed to evaluate whether stroke patients with cancer had poor clinical outcomes after use of IV t-PA. We reviewed ischemic stroke patients with active cancer treated with isolated IV t-PA between April 2010 and March 2015 at three national university hospitals from the registry for ischemic stroke in Korea. The clinical outcomes of early neurological deterioration (END, hemorrhagic transformation, in-hospital mortality, 3-month modified Rankin scale (mRS, the National Institutes of Health Stroke Scale (NIHSS discharge score, and duration of hospitalization were compared. We enrolled a total of 12 patients, and the cohort showed poor outcomes including 4 (33% END events, 7 (58% hemorrhagic transformations, 3 (25% in-hospital mortality cases, and 7 (58% poor mRS (3–6 scores. Additionally, the cryptogenic stroke group (n = 6 more frequently had high mRS scores (P = 0.043 as well as tendencies for frequent END events, hemorrhagic transformations, in-hospital mortality cases, and higher discharge NIHSS scores without statistical significance. In conclusion, ischemic stroke patients with active cancer, especially those with a cryptogenic mechanism, showed poor clinical outcomes after use of IV t-PA.

    Material and Methods: Our randomised, double-blind study was applied to ASA I-III, 18-75 years old 50 patients scheduled for transurethral surgery. The patients were divided into two groups and spinal anesthesia with 5% levobupivacaine 12.5 mg was administered to all patients. Intravenous dexmedetomidine was received 1 and micro;g/kg for loading dose before 0.5 and micro;g/kg/hour infusion to Group D (n=25. Saline infusion was given 1 and micro;g/kg for loading dose before 0.5 and micro;g/kg/hour infusion to Group S (n=25. Systolic, diastolic and mean arterial pressure, heart rate, peripheral oxygen saturation values, pain and sedation score, the level and duration of motor and sensorial block, recovery and patient comfort score and side effects were recorded. Results: Time to reach maximum block level and duration of spinal anesthesia were longer in Group D than Group S. Sedation scores were significantly higher in Group D than Group S intraoperatively (except 1th minute and postoperatively 10th and 15th minutes. The incidence of side effects, postoperative recovery and patient comfort values were similar between the groups. Conclusion: We found that dexmedetomidine prolongs duration of motor block, provides safe and effective sedation without increasing the incidence of side effect in the patients under spinal anesthesia.

Response was quantified as 1 to 25%, 25% to 50%, 50 to 75% and 75 to 100% of terminal hair growth by mapping and serial photographs. They were examined monthly for side effects of steroids. Six patients (5 male and 1 female with a mean age of 32 years were recruited. They had alopecia areata for a period ranging from 3 months to 2.5 years. All the six cases did not show further worsening of alopecia after 3 pulses. However, two of them showed less than 25% hair growth after 4 pulses and did not turn up for follow up. In 2 cases, 25 to 50% growth was observed an 50 to 75% growth was seen in 2 patients (one of them with ophiasic pattern after 6 pulses. The results were cosmetically acceptable for three of them. No adverse effect to steroids was encountered and the patients are still under follow up. The preliminary results show that dexamethasone pulse therapy is safe and effective for extensive alopecia areata.

    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.

    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 present study aimed to compare the therapeutic efficacy of dimenhydrinate and piracetam in patients with vertigo. A blinded, parallel group, superiority, randomised clinical trial was carried out on patients who presented to the emergency department (ED) with vertigo. Healthy adult patients presenting to the ED with undifferentiated vertigo were included in the study. The efficacy of intravenous dimenhydrinate (100 mg) and intravenous piracetam (2000 mg) for reducing the intensity of vertigo was compared in two randomised treatment groups using a 10-point numeric rating scale (NRS). The determination of NRS scores was performed at presentation and at the 30th minute of presentation, after the study drug was implemented, both in immobile and ambulatory positions. The primary outcome variable was reduction in vertigo intensity documented on the NRS at the 30th minute after medication administration, analysed by intention to treat. A total of 94 patients were included in the randomisation (n=47 in both groups). The baseline NRS scores were 7.55±2.00 in the dimenhydrinate group and 8.19±1.79 in the piracetam group. The changes from baseline for dimenhydrinate and piracetam were 2.92±3.11 and 3.75±3.40 (difference -0.83 (95% CI -2.23 to 0.57)) in the immobile position and were 2.04±3.07 and 2.72±2.91 (difference -0.68 (95% CI -2.03 to 0.67)) in the ambulatory position. Rescue medication need was similar in both treatment groups (p=0.330), and only one adverse reaction was reported. We found no evidence of a difference between dimenhydrinate and piracetam in relieving the symptoms of vertigo. Clinical Trials Registration ID: NCT01890538.

    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.

    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 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

    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.

    The aim of this study was to assess the efficacy and safety of a single intravenous (i.v.) bolus of dexketoprofen trometamol compared with an i.v. infusion of dipyrone in patients with moderate to severe pain due to renal colic. A total of 308 patients with renal colic and visual analog scale (VAS) score >/=40 mm participated in a multicenter, randomized, double blind, double-dummy, parallel, and active-controlled study and were randomized to dexketoprofen 25 mg (n = 101), dexketoprofen 50 mg (n = 104), and dipyrone 2 g (n = 103). Mean [+/- standard deviation (SD)] total pain relief (TOTPAR) scores were similar in the dexketoprofen 50 mg (15.3 +/- 8.6) and dipyrone (15.5 +/- 8.6) and slighly higher than in dexketoprofen 25 mg (13.5 +/- 8.6), although significant differences were not achieved. In the same way, patients in the dexketoprofen 50 mg and dipyrone groups showed higher scores in the sum of pain intensity differences (SPID) and the sum of analogue pain intensity differences (SAPID) than patients in the dexketoprofen 25 mg group, reaching statistical significance in comparison with dexketoprofen 25 mg and dipyrone for SPID and SAPID (p dexketoprofen during the first 30 min after drug administration (p Dexketoprofen 50 mg and dipyrone groups had 66% and 70%, respectively, of patients with at least 50% of maximum obtainable TOTPAR in comparison with 56% in the dexketoprofen 25 mg group. The study medications were well tolerated. Dexketoprofen 50 mg administered as a single i.v. bolus was effective for the relief of moderate to severe pain in patients with renal colic, with a good safety profile and efficacy similar to i.v. dipyrone 2 g. Dexketoprofen produced analgesia that was faster in onset.

    To describe the design and implementation of "INFUSION TOOLBOX," a software tool to control and monitor multiple intravenous drug infusions simultaneously using pharmacokinetic and pharmacodynamic principles. INFUSION TOOLBOX has been designed to present a graphical interface. Object Oriented design was used and the software was implemented using Smalltalk, to run on a PC. Basic tools are available to manage patient, drugs, pumps and reports. These tools are the PatientPanel, the DrugPanel, the PumpPanel and the HistoryPanel. The screen is built dynamically. The panels may be collapsed or closed to avoid a crowded display. We also built control panels such as the Target ControlPanel which calculates the best infusion sequence to bring the drug concentration in the plasma compartment to a preset value. Before drug delivery, the user enters the patient's data, selects a drug, enters its dilution factor and chooses a pharmacokinetic model. The calculated plasma concentration is continually displayed and updated. The anesthetist may ask for the history of the delivery to obtain a graphic report or to add events to the logbook. A panel targeting the effect is used when a pharmacodynamic model is known. Data files for drugs, pumps and surgery are upgradable. By creating a resizeable ControlPanel we enable the anesthetist to display the information he wishes, when he wishes it. The available panels are diverse enough to meet the anesthetist needs; they may be adapted to the drug used, pumps used and surgery. It is the anesthetist who builds dynamically its different control screens. By adopting an evolutionary solution model we have achieved considerable success in building our drug delivery monitor. In addition we have gained valuable insight into the anesthesia information domain that will allow us to further enhance and expand the system.

    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.

    Phosphodiesterase inhibitors such as milrinone can relieve symptoms and improve hemodynamics in patients with advanced congestive heart failure. We retrospectively evaluated the hemodynamic and clinical outcomes of long-term combination therapy with intravenous milrinone and oral β-blockers in 65 patients with severe congestive heart failure (New York Heart Association class IV function and ejection fraction milrinone. Oral medical therapy was maximized when possible. The mean duration of milrinone treatment in this combination-treatment group was 269 days (range, 14–1,026 days). Functional class improved from IV to II–III with milrinone therapy. Twenty-four such patients tolerated β-blocker up-titration and were successfully weaned from milrinone. Sixteen patients (31%) died while receiving combination therapy; one died of sudden cardiac death (on treatment day 116); the other 15 died of progressive heart failure or other complications. Hospital admissions during the previous 6 months and admissions within 6 months after milrinone initiation stayed the same. Meanwhile, the total number of hospital days decreased from 450 to 380 (a 15.6% reduction), and the mean length of stay decreased by 1.4 days (a 14.7% reduction). We conclude that 1) milrinone plus β-blocker combination therapy is an effective treatment for heart failure even with β-blocker up-titration, 2) weaning from milrinone may be possible once medications are maximized, 3) patients' functional status improves on the combination regimen, and 4) treatment-related sudden death is relatively infrequent during the combination regimen.

    Full Text Available Introduction: From its initial report on two female patients in 1979 by J.O. Susac, Susac syndrome (SuS or SICRET (small infarctions of cochlear, retinal and encephalic tissue has persisted as an elusive entity. To date the available evidence for its treatment is based on case reports and case series. The largest systematic review described only 304 reported cases since the 1970s. Here we presented the first reported case to our knowledge in Mexican population and the unusual presentation in a pregnant patient. Case presentation: A 34-year-old Hispanic woman was brought to the ER in our hospital for apathy and behavioral changes. Upon arrival at the ER, her husband described a one-month history of behavioral changes with apathy, progressive abulia, visuospatial disorientation, and gait deterioration. The initial lab test shows no significance except by a positive qualitative hCG. An MRI was obtained and showed hyperintense periventricular white matter lesions in T2 and FLAIR sequences also involving bilateral basal ganglia and with predominant affection of the corpus callosum, in addition to infratentorial cerebellar lesions. After treatment with intravenous immunoglobulins a marked and prompt clinical and radiological improvement was observed. Conclusion: SuS is still an elusive disease. To date, no definitive score or clinical feature can predict the outcome of the disease. The presentation during pregnancy is also rare and therefore the optimal treatment and the prognosis is unknown. We hope that this article will serve as a foundation for future research.

    Full Text Available Background and Aims: Perioperative beta blockers are also being advocated for modulation of acute pain and reduction of intraoperative anesthetic requirements. This study evaluated the effect of perioperative use of esmolol, an ultra short acting beta blocker, on anesthesia and modulation of post operative pain in patients of laproscopic cholecystectomy. Material and Methods: Sixty adult ASA I & II grade patients of either sex, scheduled for laparoscopic cholecystectomy under general anesthesia, were enrolled in the study. The patients were randomly allocated to one of the two groups E or C according to computer generated numbers. Group E- Patients who received loading dose of injection esmolol 0.5 mg/kg in 30 ml isotonic saline, before induction of anesthesia, followed by an IV infusion of esmolol 0.05 μg/kg/min till the completion of surgery and Group C- Patients who received 30 ml of isotonic saline as loading dose and continuous infusion of isotonic saline at the same rate as the esmolol group till the completion of surgery. Results: The baseline MAP at 0 minute was almost similar in both the groups. At 8th minute (time of intubation, MAP increased significantly in group C as compared to group E and remained higher than group E till the end of procedure. Intraoperatively, 16.67% of patients in group C showed somatic signs as compared to none in group E. The difference was statistically significant. 73.33% of patients in group C required additional doses of Inj.Fentanyl as compared to 6.67% in group E. Conclusions: We conclude that intravenous esmolol influences the analgesic requirements both intraoperatively as well as postoperatively by modulation of the sympathetic component of the pain i.e. heart rate and blood pressure.

    The Surgical Care Improvement Program endorses mandatory compliance with approved intravenous prophylactic antibiotics; however, oral antibiotics are optional. We hypothesized that surgical site infection (SSI) rates may vary depending on the choice of antibiotic prophylaxis. A retrospective cohort study of elective colorectal procedures using Veterans Affairs Surgical Quality Improvement Program (VASQIP) and SSI outcomes data was linked to the Office of Informatics and Analytics (OIA) and Pharmacy Benefits Management (PBM) antibiotic data from 2005 to 2009. Surgical site infection rates by type of IV antibiotic agent alone (IV) or in combination with oral antibiotic (IV + OA) were determined. Generalized estimating equations were used to examine the association between type of antibiotic prophylaxis and SSI for the entire cohort and stratified by use of oral antibiotics. After 5,750 elective colorectal procedures, 709 SSIs (12.3%) developed within 30 days. Oral antibiotic + IV (n = 2,426) had a lower SSI rate than IV alone (n = 3,324) (6.3% vs 16.7%, p antibiotic given (p ≤ 0.0001). Generalized estimating equations adjusting for significant covariates of age, body mass index, procedure work relative value units, and operation duration demonstrated an independent protective effect of oral antibiotics (odds ratio [OR] 0.37, 95% CI 0.29 to 0.46), as well as increased rates of SSI associated with ampicillin/sulbactam (OR 2.21, 95% CI 1.37 to 3.56) and second generation cephalosporins (cefoxitin, OR 2.50, 95% CI 1.83 to 3.42; cefotetan, OR 2.70, 95% CI 1.72 to 4.22) when compared with first generation cephalosporin/metronidazole. The choice of IV antibiotic was related to the SSI rate; however, oral antibiotics were associated with reduced SSI rate for every antibiotic class. Published by Elsevier Inc.

Design: Non randomised controlled observational study Study: Twenty four (n=24 CIS patients were recruited with the inclusion criteria as: 3 months–2years of stroke onset, hand muscle power (MRC grade at least 2; Brunnstrom stage of recovery: II-IV; NIHSS of 4-15, comprehendible. Fugl Meyer, modified Barthel Index (mBI and functional imaging parameters were used for assessment at baseline, 8 weeks and at 24 weeks. Twelve patients were administered with mean 54.6 million cells intravenously followed by 8 weeks of physiotherapy. Twelve patients served as controls. All patients were followed up at 24 weeks. Outcomes: The laboratory and radiological outcome measures were within normal limits in MNC group. Only mBI showed statistically significant improvement at 24 weeks (p<0.05 whereas the mean FM, MRC, Ashworth tone scores in the MNC group were high as compared to control group. There was an increased number of cluster activation of Brodmann areas BA 4, BA 6 post stem cell infusion compared to controls indicating neural plasticity. Cell therapy is safe and feasible which may facilitate restoration of function in CIS.

    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.

    Full Text Available &lt;b&gt;Purpose:&lt;/b&gt; It has been reported that 10% to 20% of children with Kawasaki disease (KD will not respond to intravenous immunoglobulin (IVIG treatment. In this study, we aimed to identify useful predictors of therapeutic failure in children with KD. &lt;b&gt;Methods:&lt;/b&gt; We examined 309 children diagnosed with KD at the Kyungpook National University Hospital and the Inje University Busan Paik Hospital between January 2005 and June 2011. We retrospectively reviewed their medical records and analyzed multiple parameters in responders and nonresponders to IVIG. &lt;b&gt;Results:&lt;/b&gt; Among the 309 children, 30 (9.7% did not respond to IVIG. They had significantly higher proportion of neutrophils, and higher levels of aspartate aminotransferase, alanine aminotransferase (ALT, total bilirubin, and N-terminal fragment of B-type natriuretic peptide than did responders. IVIGnonresponders had a significantly longer duration of hospitalization, and more frequently experienced coronary artery lesion, and sterile pyuria. No differences in the duration of fever at initial treatment or, clinical features were noted. &lt;b&gt;Conclusion:&lt;/b&gt; Two independent predictors (ALT?#248;4 IU/L, total bilirubin?#240;.9 mg/dL for nonresponse were confirmed through multivariate logistic regression analysis. Thus elevated ALT and total bilirubin levels might be useful in predicting nonresponse to IVIG therapy in children with KD.

    Twelve patients were treated with continuous intravenous (24-hour) infusions of bromodeoxyuridine (BUdR) at 650 or 1000 mg/m2/d for up to two weeks. Myelosuppression, especially thrombocytopenia, was the major systemic toxicity and limited the infusion period to nine to 14 days. However, bone marrow recovery occurred within seven to ten days, allowing for a second infusion in most patients. Local toxicity (within the radiation field) was minimal, with the exception of one of four patients, who underwent abdominal irradiation. Pharmacology studies revealed a steady-state arterial plasma level of 6 x 10(-7) mol/L and 1 x 10(-6) mol/L during infusion of 650 and 1000 mg/m2/d, respectively. In vivo BUdR uptake into normal bone marrow was evaluated in two patients by comparison of preinfusion and postinfusion in vitro radiation survival curves of marrow CFUc with enhancement ratios (D0-pre/D0-post) of 1.8 (with 650 mg/m2/d) and 2.5 (with 1000 mg/m2/d). In vivo BUdR incorporation into normal skin and tumor cells using an anti-BUdR monoclonal antibody and immunohistochemistry was demonstrated in biopsies from three patients revealing substantially less cellular incorporation into normal skin (less than 10%) compared with tumor (up to 50% to 70%). The authors conclude that local and systemic toxicity of continuous infusion of BUdR at 1000 mg/m2/d for approximately two weeks is tolerable. The observed normal tissue toxicity is comparable with previous clinical experience with intermittent (12 hours every day for two weeks) infusions of BUdR. Theoretically, a constant infusion should allow for greater incorporation of BUdR into cycling tumor cells and thus, for further enhancement of radiosensitization

    Studies were conducted to examine the absorption and disposition kinetics of insulin in dogs following intravenous (IV) and subcutaneous (SC) administration of commercial preparations. After IV and SC dosing, the plasma levels were described by models which considered basal insulin level contributions. Intersubject variation in the disposition kinetics was small with half-lives of 0.52 +/- 0.05 h and total body clearances of 16.21 +/- 2.08 ml min-1 kg-1. Calculated insulin plasma secretion rates in the canines were 14.4 +/- 3.3 mUh-1 kg-1. Following SC injection of regular insulin, the rate and extent of absorption were noted to be quite variable. The absorption process appeared first-order with half-life values of 2.3 +/- 1.3 h and extents of absorption of 78 +/- 15 per cent with a range of 55-101 per cent. Insulin absorption from SC NPH preparations was evaluated as being composed of two zero-order release phases, a rapid and a slow release phase. With a dose of 1.65 U kg-1, the rapid release phase had an average duration of 1.5 h and a rate of 580 +/- 269 mUh-1 (4.2 per cent of dose) while the slow phase had a zero-order rate of 237 +/- 92 mU h-1 which continued beyond 12 h. The extent of absorption from the NPH preparation was 23.6 +/- 5.1 per cent and was significantly lower than that for the regular injection.

  13. Intravenous Iron Administration and Hypophosphatemia in Clinical Practice

    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.

    Full text: We performed a prospective study to determine frequency of presence of gallbladder varices (GBV) by intravenous CT portography (CTP) in patients with extrahepatic portal venous obstruction (EHPVO). 90 patients (age range: 2-55 years) with EHPVO (initially diagnosed on abdominal sonography) underwent CTP using a subsecond helical CT scanner. Axial overlapping sections of 2mm were obtained with collimation 3mm and table speed 4.5mm/sec (pitch 1.5). Presence and patterns of GBV were studied. CTP demonstrated GBV in 54 (60%) of 90 patients.GBV were said to be present when one or more of the following findings were seen: diffuse wall enhancement (26/90), pinpoint areas of enhancement in GB wall (33/90), obvious large collaterals in GB wall (8/90) and pericholecystic collaterals (49/90). Presence of GBV did not correlate with the site and extent of EHPVO. Contiguous intrahepatic collaterals extending from GB bed to intrahepatic portal vein branches were seen in 41 of 54 (76%) of patients with GBV, suggesting the role of GBV serving as bridging portoportal collaterals. Hepatic perfusion defects were seen in 5/54 patients with GBV and were not seen in remaining 36/90 patients of EHPVO. GB calculi were seen in only 4/54 cases with GBV (as determined on sonography) suggesting no increase in risk for cholelithiasis. GBV commonly develop as bridging collaterals in patients with EHPVO. CTP is very useful in detecting these varices and planning biliary surgery, given the frequency of iatrogenic surgical bleeding in these patients. Copyright (2002) Blackwell Science Pty Ltd

    The minimal model approach to estimating insulin sensitivity (Sl) and glucose effectiveness in promoting its own disposition at basal insulin (SG) is a powerful tool that has been underutilized given its potential applications. In part, this has been due to its inability to separate insulin and glucose effects on peripheral uptake from their effects on hepatic glucose inflow. Prior enhancements, with radiotracer labeling of the dosage, permit this separation but are unsuitable for use in pregnancy and childhood. In this study, we labeled the intravenous glucose tolerance test (IVGTT) dosage with [6,6- 2 H 2 ]glucose, [2- 2 H]glucose, or both stable isotopically labeled glucose tracers and modeled glucose kinetics in six postabsorptive, nonobese adults. As previously found with the radiotracer model, the tracer-estimated S*l derived from the stable-label IVGTT was greater than Sl in each case except one, and the tracer-estimated SG* was less than SG in each instance. More importantly, however, the stable-label IVGTT estimated each parameter with an average precision of +/- 5% (range 3-9%) compared to average precisions of +/- 74% (range 7-309%) for SG and +/- 22% (range 3-72%) for Sl. In addition, because of the different metabolic fates of the two deuterated tracers, there were minor differences in basal insulin-derived measures of glucose effectiveness, but these differences were negligible for parameters describing insulin-stimulated processes. In conclusion, the stable-label IVGTT is a simple, highly precise means of assessing insulin sensitivity and glucose effectiveness at basal insulin that can be used to measure these parameters in individuals of all ages, including children and pregnant women

    Twenty-four patients with locally advanced (19 patients) or metastatic (5 patients) tumors were treated in a Phase I study combining constant intravenous infusions of iododeoxyuridine (IUdR) and hyperfractionated radiation therapy. IUdR was given as a constant infusion for 12 hours/day for two separate 14-day infusion periods in most patients. The dose of IUdR was escalated from 250 to 1200 mg/m2/12-hour infusion in this study. The initial tumor volume was treated to 45 Gy/1.5 Gy BID/3 weeks followed by a cone-down boost to 20-25 Gy/1.25 Gy BID/2 weeks after a planned 2-week break. THe IUdR infusion preceded the initial and cone-down irradiation by 1 week. Local acute toxicity (within the radiation volume) was uncommon and few patients required an alteration of the planned treatment schedule. Two patients developed late local toxicity with one patient showing clinical signs of radiation hepatitis and another patient developing a large bowel obstruction that required surgical bypass. Dose-limiting systemic toxicity was confined to the bone marrow with moderate to severe thrombocytopenia developing on Day 10-14 of infusions at 1200 mg/m2/12 hours. Mild stomatitis and partial alopecia occurred in some patients at this dose level. No systemic skin toxicity was seen. Pharmacology studies revealed steady-state arterial plasma levels of IUdR of 1 to 8 X 10(-6) M over the dose range used. In vivo IUdR incorporation into tumors was studied in three patients with high-grade sarcomas using an anti-IUdR monoclonal antibody and immunohistochemistry and demonstrated incorporation in up to 50-70% of tumor cells. The preliminary treatment results, particularly in patients with unresectable sarcomas, are encouraging.

    Full Text Available Ultraperformance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF MS was used to characterize ornidazole metabolites in human bile after intravenous doses. A liquid chromatography tandem mass spectrometry (LC–MS/MS assay was developed for the determination of the bile level of ornidazole. Bile samples, collected from four patients with T-tube drainage after biliary tract surgery, were prepared by protein precipitation with acetonitrile before analysis. A total of 12 metabolites, including 10 novel metabolites, were detected and characterized. The metabolites of ornidazole in human bile were the products of hydrochloride (HCl elimination, oxidative dechlorination, hydroxylation, sulfation, diastereoisomeric glucuronation, and substitution of NO2 or Cl atom by cysteine or N-acetylcysteine, and oxidative dechlorination followed by further carboxylation. The bile levels of ornidazole at 12 h after multiple intravenous infusions were well above its minimal inhibitory concentration for common strains of anaerobic bacteria.

  18. Vented spikes improve delivery from intravenous bags with no air headspace.

    Flexible plastic bags are the container of choice for most intravenous (i.v.) infusions. Under certain circumstances, however, the air-liquid interface present in these i.v. bags can lead to physical instability of protein biopharmaceuticals, resulting in product aggregation. In principle, the air headspace present in the bags can be removed to increase drug stability, but experiments described here show that this can result in incomplete draining of solution from the bag using gravity delivery, or generation of negative pressure in the bag when an infusion pump is used. It is expected that these issues could lead to incomplete delivery of medication to patients or pump-related problems, respectively. However, here it is shown that contrary to the standard pharmacy practice of using nonvented spikes with i.v. bags, the use of vented spikes with i.v. bags that lack air headspace allows complete delivery of the dose solution without impacting the physical stability of a protein-based drug. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

    1984-01-01

    The influence of intravenous injection of ioxaglate (Hexabrix, 320 mg I/ml) on various biochemical, coagulation and fibrinolytic parameters, fractionated plasma proteins, precordial ECG and blood pressure was prospectively and sequentially studied in 9 healthy volunteers. One ml/kg body weight of the contrast medium was injected within one minute into an antecubital vein. Small, but statistically significant, changes in some of the biochemical parameters were found during the observation period, 2 to 4 days. All values of the biochemical parameters were, however, within the normal reference range for each parameter. No significant alterations were seen in the coagulation parameters. Increased fibrinolysis was recorded in some subjects both before and after the injection. No fibrinolytic degradation products were found indicating that the fibrinolysis was nominal. No significant changes were observed in the fractionated plasma proteins. The heart rate decreased significantly 15 seconds after commencing the injection. No significant changes in blood pressure were recorded. Two participants became nauseated and one of them vomited during the injection. Apart from this, no adverse effects were noted. No clinically significant changes following the injections were found. (orig.)

  20. The course of hepatitis E virus infection in pigs after contact-infection and intravenous inoculation

    2009-02-01

    Full Text Available Abstract Background Worldwide, hepatitis E virus (HEV genotype 3 is observed in pigs and transmission to humans is implied. To be able to estimate public health risks from e.g. contact with pigs or consumption of pork products, the transmission routes and dynamics of infection should be identified. Hence, the course of HEV-infection in naturally infected pigs should be studied. Results To resemble natural transmission, 24 HEV-susceptible pigs were infected either by one-to-one exposure to intravenously inoculated pigs (C1-pigs; n = 10, by one-to-one exposure to contact-infected pigs (C2-pigs: n = 7; C3-pigs: n = 5 or due to an unknown non-intravenous infection route (one C2-pig and one C3-pig. The course of HEV-infection for contact-infected pigs was characterized by: faecal HEV RNA excretion that started at day 7 (95% confidence interval: 5–10 postexposure and lasted 23 (19–28 days; viremia that started after 13 (8–17 days of faecal HEV RNA excretion and lasted 11 (8–13 days; antibody development that was detected after 13 (10–16 days of faecal HEV RNA excretion. The time until onset of faecal HEV RNA excretion and onset of viremia was significantly shorter for iv-pigs compared to contact-infected pigs, whereas the duration of faecal HEV RNA excretion was significantly longer. At 28 days postinfection HEV RNA was detected less frequently in organs of contact-infected pigs compared to iv-pigs. For contact-infected pigs, HEV RNA was detected in 20 of 39 muscle samples that were proxies for pork at retail and in 4 of 7 urine samples. Conclusion The course of infection differed between infection routes, suggesting that contact-infection could be a better model for natural transmission than iv inoculation. Urine and meat were identified as possible HEV-sources for pig-to-pig and pig-to-human HEV transmission.

  12. 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.

    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.

    1974-01-01

    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

    The author previously described his experience in 450 patients with congenital heart disease using intravenous digital subtraction angiography (DSA) to define cardiac anatomy. He has been impressed by the utility of DSA in the evaluation of patients with congenital heart disease. It is now an integral part of his clinical practice to perform intravenous DSA studies both pre- and postoperatively on an inpatient as well as outpatient basis. This chapter details his DSA experience with complex forms of congenital heart disease

    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 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.

    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.

    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.

    Ammi visnaga L. (syn. Khella, Apiaceae) preparations have traditionally been used in the Middle East for the treatment of kidney stone disease. Visnagin, a furanocoumarin derivative, is one of the main compounds of Ammi visnaga with potential effects on kidney stone prevention. To date, no information is available about the pharmacokinetic (PK) properties of visnagin. It was the aim of the study to characterize the PK properties of visnagin after intravenous (i.v.) bolus administration in rats and to develop an adequate model for the description of the observed data, including model parameter estimates. Therefore, three doses of visnagin (1.25, 2.5, and 5mg/kg) solubilized in 25% Captisol® were administered by i.v. bolus injection to male Sprague-Dawley rats. Plasma samples were extracted and subsequently analyzed using a validated LC-MS/MS method. Both non-compartmental and compartmental PK analyses were performed. A stepwise model building approach was applied including nonlinear mixed effect modeling for final model selection and to obtain final model estimates in NONMEM VI. The average areas under the curve (AUC(0-last)) after doses of 1.25, 2.5, and 5mg/kg were 1.03, 3.61, and 12.6 mg *h/l, respectively. The shape of the plasma concentration-time profiles and the observed disproportionate increase in AUC(0-last) with increasing dose suggested nonlinearity in the elimination of visnagin. A two-compartment Michaelis-Menten model provided the best fit with following typical values of the parameter estimates: 2.09 mg/(l*h) (V(max)), 0.08 mg/l (K(M)), 0.175 l (V(C)), 1.0 h⁻¹ (k₁₂), and 1.22 h⁻¹ (k₂₁). Associated inter-subject variability estimates (% CV) for V(max), K(M) and V(C) were 21.8, 70.9, and 9.2, respectively. Intra-subject variability (constant CV error model) was estimated to be 7.0%. The results suggest the involvement of a saturable process in the elimination of visnagin, possibly an enzyme or transporter system. Copyright © 2011

    For treatment of mild to moderate dehydration arising from viral gastroenteritis, the American Academy of Pediatrics recommends oral rehydration therapy over a 4-hour period. However, oral rehydration therapy remains largely underused by emergency physicians. Studies suggest that a major barrier is a perception that the time requirement for oral rehydration therapy is too long relative to intravenous (IV) hydration. : To test the hypothesis that children who receive IV hydration for gastroenteritis spend significantly less than 4 hours in the emergency department (ED). A prospective case series involving a consecutive sample of 549 children treated with IV hydration for mild to moderate dehydration at an urban pediatric ED. Treatment time was defined as period elapsed between when a physician placed a patient in an ED room and when he/she discharged the patient. We excluded time spent in the waiting room before seeing a physician. Using a standardized procedure, we collected data in September/October 2000 (fall), November 2000 to January 2001 (winter), and April/May 2001 (spring). To provide a measure of average pass-through time at this ED, we also collected data on all patients treated during consecutive 7-day periods in the fall (n = 502), winter (n = 776), and spring (n = 653). We performed univariate analysis of continuous variables using t tests for independent samples. 549 subjects received IV treatment for dehydration; of whom 55% were female, and mean age was 9.7 years. Treatment time for patients undergoing IV hydration exceeded 4 hours (mean = 5.4 +/- 2.4 hours; median = 5.0 hours). Mean time for IV treatment of dehydration was significantly longer than the mean time for treating other patients (5.4 vs. 1.2 hours, P Pediatrics for oral rehydration. The data did not support the perception by emergency physicians that children treated with IV hydration spend significantly less time than 4 hours in the ED. These findings have implications for addressing one

    Objective: To assess the beneficial effect of intravenous pamidronate treatment in children with osteogenesis imperfecta (OI). Study Design: Experimental study. Place and Duration of Study: Endocrine Unit at the National Institute of Child Health, Karachi, Pakistan, from January 2007 to December 2011. Methodology: All children diagnosed with osteogenesis imperfecta on the basis of repeated spontaneous fractures and typical radiological findings registered during the study period, were included in this study. Pamidronate therapy were offered to those with more than 3 fractures per year or had platyspondyly. Pamidronate disodium was diluted in isotonic saline and administered by slow ravenous infusion over 3 hours in a dosage 1 mg/kg/day for 3 consecutive days 3 monthly for 2 years. Fracture rate, bone mineral density (BMD), mobility score, wellbeing and pain episodes were evaluated at baseline and 2 years after the treatment. Good response was defined as less than 2 fractures per year or mobility score improvement and poor response as more than 2 fracture per year with mobility score less than 2. Results: Seventy two patients were included in this study. There were 40 boys and 32 girls with mean age of 3.64 +- 3.2 years. The annual fracture rate decreased overall from 5.8 +- 1.61 to 0.6 +- 0.93 (p < 0.001). BMD Z-score improved from -5.3 +- 1.74 to -1.7 +- 0.72 (p < 0.001). Mobility score was 0.94 +- 1.30 at baseline and 2.5 +- 1.02 at the end of the treatment (p < 0.001). Wellbeing gained from 3.63 +- 1.44 to 7.8 +- 1.18 (p < 0.001) and pain episode improved from 24.1 +- 8.15 to 2.7 +- 8.31 (p < 0.001). Good response was noted in 92% of patients and poor response in 8% patients. Conclusion: Bisphosphonate seems to be an effective symptomatic treatment for children with osteogenesis imperfecta irrespective of severity of mutation or clinical phenotype. Cyclical bisphosphonate therapy has a positive effect on fracture rate, BMD, mobility score, wellbeing and pain

    Delay in appropriate antibiotic therapy is associated with an increase in mortality and prolonged length of stay. Automatic dispensing machines decrease the delivery time of intravenous (IV) antibiotics to patients in the emergency department (ED). However, when IV antibiotics are not reviewed by pharmacists before being administered, patients are at risk for receiving inappropriate antibiotic therapy. The objective of this study was to determine if a difference exists in the time to administration of appropriate antibiotic therapy before and after implementation of prospective verification of antibiotics in the ED. This retrospective, institutional review board-approved preimplementation vs postimplementation study evaluated patients 18years or older who were started on IV antibiotics in the ED. Patients were excluded if pregnant, if the patient is a prisoner, if no cultures were drawn, or if the patient was transferred from an outside facility. Appropriate antibiotic therapy was based on empiric source-specific evidence-based guidelines, appropriate pharmacokinetic and pharmacodynamic properties, and microbiologic data. The primary end point was the time from ED arrival to administration of appropriate antibiotic therapy. Of the 1628 evaluated, 128 patients met the inclusion criteria (64 pre vs 64 post). Patients were aged 65.2±17.0years, with most of infections being pneumonia (44%) and urinary tract infections (18%) and most patients being noncritically ill. Time to appropriate antibiotic therapy was reduced in the postgroup vs pregroup (8.1±8.6 vs 15.2±22.8hours, respectively, P=.03). In addition, appropriate empiric antibiotics were initiated more frequently after the implementation (92% post vs 66% pre; P=.0001). There was no difference in mortality or length of stay between the 2 groups. Prompt administration of the appropriate antibiotics is imperative in patients with infections presenting to the ED. The impact of prospective verification of

    To date, there is no information on the intravenous (i.v.) posaconazole pharmacokinetics for intensive care unit (ICU) patients. This prospective observational study aimed to describe the pharmacokinetics of a single dose of i.v. posaconazole in critically ill patients. Patients with no history of allergy to triazole antifungals and requiring systemic antifungal therapy were enrolled if they were aged ≥18 years, central venous access was available, they were not pregnant, and they had not received prior posaconazole or drugs interacting with posaconazole. A single dose of 300 mg posaconazole was administered over 90 min. Total plasma concentrations were measured from serial plasma samples collected over 48 h, using a validated chromatographic method. The pharmacokinetic data set was analyzed by noncompartmental methods. Eight patients (7 male) were enrolled with the following characteristics: median age, 46 years (interquartile range [IQR], 40 to 51 years); median weight, 68 kg (IQR, 65 to 82 kg); and median albumin concentration, 20 g/liter (IQR, 18 to 24 g/liter). Median (IQR) pharmacokinetic parameter estimates were as follows: observed maximum concentration during sampling period ( C max ), 1,702 ng/ml (1,352 to 2,141 ng/ml); area under the concentration-time curve from zero to infinity (AUC 0-∞ ), 17,932 ng · h/ml (13,823 to 27,905 ng · h/ml); clearance (CL), 16.8 liters/h (11.1 to 21.7 liters/h); and volume of distribution ( V ), 529.1 liters (352.2 to 720.6 liters). The V and CL were greater than 2-fold and the AUC 0-∞ was 39% of the values reported for heathy volunteers. The AUC 0-∞ was only 52% of the steady-state AUC 0-24 reported for hematology patients. The median of estimated average steady-state concentrations was 747 ng/ml (IQR, 576 to 1,163 ng/ml), which is within but close to the lower end of the previously recommended therapeutic range of 500 to 2,500 ng/ml. In conclusion, we observed different pharmacokinetics of i.v. posaconazole in

    Full Text Available Barriers to developing treatments for human status epilepticus (SE include the inadequacy of experimental animal models. In contrast, naturally-occurring canine epilepsy is similar to the human condition and can serve as a platform to translate research from rodents to humans. The objectives of this study were to characterize the pharmacokinetics (PK of an intravenous (IV dose of topiramate (TPM in dogs with epilepsy, and evaluate its effect on intracranial electroencephalographic (iEEG features. Five dogs with naturally occurring epilepsy were used for this study. Three were getting at least one antiseizure drug as maintenance therapy including phenobarbital (PB. Four (ID 1-4 were used for the 10 mg/kg IV TPM + PO TPM study, and three (ID 3-5 were used for the 20 mg/kg IV TPM study. IV TPM was infused over 5 minutes at both doses. The animals were observed for vomiting, diarrhea, ataxia, and lethargy. Blood samples were collected at scheduled pre- and post-dose times. Plasma concentrations were measured using a validated HPLC-MS method. Non-compartmental and population compartmental modeling were performed (Phoenix WinNonLin and NLME using plasma concentrations from all dogs in the study. Intracranial EEG (iEEG was acquired in one dog. The difference between averaged iEEG energy levels at 15 minutes pre- and post-dose was assessed using a Kruskal-Wallis test. No adverse events were noted. Topiramate concentration-time profiles were best fit by a two-compartment model. PB co-administration was associated with a 5.6 fold greater clearance and a ~4 fold shorter elimination half-life. iEEG data showed that TPM produced a significant energy increase at frequencies >4 Hz across all 16 electrodes within 15 minutes of dosing. Simulations suggested that dogs on an enzyme inducer would require 25 mg/kg, while dogs on non-inducing drugs would need 20 mg/kg to attain the target concentration (20-30 µg/mL at 30-minutes post-dose.This study shows that IV

    The high prevalence of extensively drug-resistant Gram-negative pathogens has forced clinicians to use colistin as a last-line therapy. Knowledge on the pharmacokinetics of colistin methanesulfonate (CMS), an inactive prodrug, and colistin has increased substantially; however, the pharmacokinetics in the Chinese population is still unknown due to lack of a CMS product in China. This study aimed to evaluate the pharmacokinetics of a new CMS product developed in China in order to optimise dosing regimens. A total of 24 healthy subjects (12 female, 12 male) were enrolled in single- and multiple-dose pharmacokinetic (PK) studies. Concentrations of CMS and formed colistin in plasma and urine were measured, and PK analysis was conducted using a non-compartmental approach. Following a single CMS dose [2.36 mg colistin base activity (CBA) per kg, 1 h infusion], peak concentrations (C max ) of CMS and formed colistin were 18.0 mg/L and 0.661 mg/L, respectively. The estimated half-life (t 1/2 ) of CMS and colistin were 1.38 h and 4.49 h, respectively. Approximately 62.5% of the CMS dose was excreted via urine within 24 h after dosing, whilst only 1.28% was present in the form of colistin. Following multiple CMS doses, colistin reached steady-state within 24 h; there was no accumulation of CMS, but colistin accumulated slightly (R AUC  = 1.33). This study provides the first PK data in the Chinese population and is essential for designing CMS dosing regimens for use in Chinese hospitals. The urinary PK data strongly support the use of intravenous CMS for serious urinary tract infections. Copyright © 2018 Elsevier B.V. and International Society of Chemotherapy. All rights reserved.

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside

    Medication errors can be harmful, especially if they involve the intravenous (IV) route of administration. A mixed-methodology study using a 5-year review of 73,769 IV-related medication errors from a national medication error reporting program indicates that between 3% and 5% of these errors were harmful. The leading type of error was omission, and the leading cause of error involved clinician performance deficit. Using content analysis, three themes-product shortage, calculation errors, and tubing interconnectivity-emerge and appear to predispose patients to harm. Nurses often participate in IV therapy, and these findings have implications for practice and patient safety. Voluntary medication error-reporting programs afford an opportunity to improve patient care and to further understanding about the nature of IV-related medication errors.

    Flat panel detector CT angiography with intravenous contrast agent injection (IV CTA) allows high-resolution imaging of cerebrovascular structures. Artifacts caused by metallic implants like platinum coils or clips lead to degradation of image quality and are a significant problem. To evaluate the influence of a prototype metal artifact reduction (MAR) algorithm on image quality in patients with intracranial metallic implants. Flat panel detector CT after intravenous application of 80 mL contrast agent was performed with an angiography system (Artis zee; Siemens, Forchheim, Germany) using a 20 s rotation protocol (200° rotation angle, 20 s acquisition time, 496 projections). The data before and after MAR of 26 patients with a total of 34 implants (coils, clips, stents) were independently evaluated by two blinded neuroradiologists. MAR improved the assessability of the brain parenchyma and small vessels (diameter metallic implants and at a distance of 6 cm (p<0.001 each, Wilcoxon test). Furthermore, MAR significantly improved the assessability of parent vessel patency and potential aneurysm remnants (p<0.005 each, McNemar test). MAR, however, did not improve assessability of stented vessels. When an intravenous contrast protocol is used, MAR significantly ameliorates the assessability of brain parenchyma, vessels, and treated aneurysms in patients with intracranial coils or clips.

    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.

    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.

    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.

    In recent years, there have been a number of pharmacological innovations for Crohn's disease (CD), a difficult-to-treat condition, including new treatment philosophies (e.g., top-down therapy) and new therapeutic options in terms of the agent and the route of administration. Three anti-tumor necrosis factor (anti-TNF-alpha) agents are available for use among CD patients in the United States: infliximab, an intravenous agent, and adalimumab and certolizumab pegol, 2 newer subcutaneous products. Infliximab is considered the "gold standard" because it has the longest clinical experience, and adalimumab and certolizumab pegol have each gained significant market share. To examine differences in effectiveness and safety between currently available intravenous and subcutaneous anti-TNF-alpha agents used to treat patients with CD. Data for this retrospective, administrative claims analysis were obtained from pharmacy and medical claims from major U.S. health plans geographically dispersed across 14 states during 2007-2011. Patients had at least 1 ICD-9-CM diagnosis for CD, 6 months pre-index eligibility, and initiated anti-TNF-alpha therapy on the index date. Patients in each cohort were propensity score matched on pre-index demographics, clinical characteristics, and baseline health care use. During the post-index period, age-sex adjusted incidence rate ratios (IRRs) of CD-related symptoms, infections, cancers, and hepatic-related conditions were compared using Cox (PH) models. The matched cohorts included 515 patients in each group, with an average age of 39 years. Median follow-up was 17.5 months in the intravenous cohort and 17.7 months in the subcutaneous cohort. In terms of effectiveness outcomes, age-sex adjusted IRRs for the subcutaneous group, with the intravenous cohort as a reference, were as follows: 0.61 (95% CI = 0.32-1.18, P = 0.14) for anal fissures; 0.97 (95% CI = 0.72-1.30, P = 0.85) for abscess; 1.08 (95% CI = 0.79-1.04, P = 0

    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

    Platelet concentrates are given to patients suffering with severe thrombocytopenia usually by a gravity transfusion procedure. Increasing patient numbers that are in need of this treatment increase the pressure on hospital staff and space. In order to combat time issues, the use of medical devices such as intravenous infusion pumps are thought to be beneficial for time and simultaneously for safety in transfusion practices. By using infusion pumps, platelet concentrates can be transfused in less time and provide accurate volume measurements. Manufacturers of infusion pumps claim that these devices are safe to be used for blood products including platelet concentrates. However, published studies were performed on older models and newer devices are on the market now. The purpose of this study is to evaluate infusion pumps, which are claimed to be suitable for blood products and to investigate the impact the pumps had on platelets. Furthermore, the study revealed if the intravenous infusion pumps are safe to be used for platelet transfusion as claimed by manufacturers. A simulated transfusion was performed using the Carefusion Alaris GP Plus volumetric pump and Fresenius Kabi Volumat Agilia infusion pump. Samples were taken from expired platelet concentrates before and after passage through the pump. All samples were investigated for full blood count that included platelet count, mean platelet volume (MPV), platelet distribution width (PDW) and a plateletcrit (PCT). The samples were then centrifuged to achieve platelet-poor plasma and then tested for lactate dehydrogenase (LDH). A power calculation performed on the statistical power analysis program G*power indicated a requirement of 82 samples for a power of 80%. Statistical analysis was performed with the IBM SPSS statistic software. A paired sample t-test was used to calculate mean, standard deviation and P values for the infusion pumps used. The Wilcoxon Signed Rank Test was used to evaluate results that had a non

    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.

    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.

    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.

    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

    2013-01-01

    Background Intravenous (IV) artesunate is the treatment of choice for severe malaria. In Europe, this treatment is only available in a few countries via named patient programmes (NPPs). As a case study, the legal and organisational aspects and pharmacovigilance of these NPPs and possibilities for harmonisation within the EU were studied over time and space using IV artesunate (Malacef) in the Netherlands, Belgium and France. Methods The legal base and organisation of NPPs in the Netherlands, Belgium and France were studied. The diffusion and cumulative availability of IV artesunate and the pharmacovigilance components were compared among the three countries using distribution data from the period 2007 through 2012. Results Artesunate has quickly gained acceptance for treating severe malaria in the Netherlands, whereas both Belgium and France have introduced this treatment more hesitantly. This difference in acceptance is due to differences in the implementation of NPP legislation among the countries. France currently has a proactive system in which treatment requires the permission for each patient and an intensive follow-up protocol. On the other hand, Belgium and Dutch NPPs are more dependent on the investigators’ initiative and are therefore potentially faster and more flexible, facilitating the discovery of adverse effects that have not been reported by more formal comparative clinical trials. Conclusions NPPs provide a unique opportunity to study both the benefits and risks of unregistered products for treating rare diseases, provided that the patients are actively vigilated. Thus, we recommend that NPPs should be harmonised throughout Europe in order to ensure equal availability of treatment and therapeutic benefit to all Europeans without compromising patient safety.

    Full Text Available Abstract Background Intravenous (IV artesunate is the treatment of choice for severe malaria. In Europe, however, no GMP-manufactured product is available and treatment data in European travellers are scarce. Fortunately, artesunate became available in the Netherlands and Belgium through a named patient programme. This is the largest case series of artesunate treated patients with severe malaria in Europe. Methods Hospitalized patients treated with IV artesunate between November 2007 and December 2010 in the Netherlands and Belgium were retrospectively evaluated. Patient characteristics, treatment and clinical outcome were recorded on a standardized form and mortality, parasite clearance times and the occurrence of adverse events were evaluated. Results Of the 68 treated patients, including 55 with severe malaria, two patients died (2/55 = 3.6%. The mean time to 50% parasite clearance (PCT50, 90% and 99% were 4.4 hours (3.9 - 5.2, 14.8 hours (13.0 - 17.2, and 29.5 hours (25.9 - 34.4 respectively. Artesunate was well tolerated. However, an unusual form of haemolytic anaemia was observed in seven patients. The relationship with artesunate remains uncertain. Conclusions Data from the named patient programme demonstrate that IV artesunate is effective and well-tolerated in European travellers lacking immunity. However, increased attention needs to be paid to the possible development of haemolytic anaemia 2-3 weeks after start of treatment. Treatment of IV artesunate should be limited to the period that IV treatment is required and should be followed by a full oral course of an appropriate anti-malarial drug.

    Case histories of two patients treated with colloidal radiogold for diffuse reticulum cell sarcoma are presented. Further analysis of the method is suggested by the unusually long survival time of one of the patients. It was concluded that, although external radiotherapy remains the treatment of choice in localized reticulum cell sarcoma, intravenous colloidal radiogold may be a useful agent in lymphosarcomas with diffuse minute neoplastic liver and spleen involvements. Intravenous colloidal radiogold can produce bone marrow depression and thrombocytopenia which can lead to death. This factor tends to argue against therapeutic use of the agent. It is suggested that no more than 50 mC Au/sup 198/ intravenously should be used for treatment of this disease. (R.M.G.)

    This article describes a recent case of ciguatera poisoning treated with intravenous mannitol. Mannitol has been used with good effect in non-controlled studies in acutely severely poisoned patients, but is not described in the treatment of chronic or milder poisoning. Our patient was a 35-year-old Niuean man who had eaten a ciguatoxic fish two weeks previously. His symptoms were not severe but were very unpleasant and restricted his ability to work. He was given a single dose of mannitol (0.66g/kg) as an intravenous infusion over two hours. His symptoms dramatically improved within 24 hours, and within a few days he felt virtually back to his former self. He experienced no side effects to the mannitol. It is suggested that intravenous mannitol may prove to be a useful treatment for mild to moderate ciguatera poisoning, and for patients who present late for treatment.

    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

    To explore whether ultrafiltration is superior to intravenous diuretics in ameliorating fluid overload and preserving renal functions in decompensated heart failure patients. By searching in Pubmed, Cochrane Library, Embase, Springer, WanFang, CQVIP, CNKI and CBM database as well as related Chinese journals, qualified randomized controlled trials (RCTs) were included for meta-analysis by Revman 5.0 and STATA 10.0. Six RCTs were included with 241 patients in ultrafiltration group and 240 patients in intravenous diuretics group. Pooled analyses demonstrated ultrafiltration was superior to intravenous diuretics in the aspects of weight loss (WMD = 1.44 kg, 95%CI:0.33-2.55 kg, P = 0.01) and fluid removal (WMD = 1.23 kg, 95%CI:0.63-1.82 kg, P diuretics in mitigating fluid overload. No intergroup difference was observed in renal function preservation, mortality or rehospitalization.

    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)

    Full Text Available In a clinical setting, where multiple administrations of the therapeutic agent are usually required to improve the therapeutic outcome, it is crucial to assess the immunogenicity of the administered nanoparticles. In this data work, we investigated the safety profile of the repeated intravenous administration of brain-targeted stable nucleic acid lipid particles (RVG-9r-targeted SNALPs. To evaluate local activation of the immune system, we performed analysis of mouse tissue homogenates and sections from cerebellum. To investigate peripheral activation of the immune system, we used serum of mice that were intravenously injected with RVG-9r-targeted SNALPs. These data are related and were discussed in the accompanying research article entitled “Intravenous administration of brain-targeted stable nucleic acid lipid particles alleviates Machado–Joseph disease neurological phenotype” (Conceição et al., in press [1].

    In recent years, there has been increasing interest in the role of intravenous lipid formulations as potential antidotes in patients with severe cardiotoxicity caused by drug toxicity. The aim of this study was to conduct a comprehensive bibliometric analysis of all human and animal studies featuring lipid emulsion as an antidote for the treatment of acute poisoning. The Scopus database search was performed on 5 February 2016 to analyse the research output related to intravenous lipid emulsion as an antidote for the treatment of acute poisoning. Research indicators used for analysis included total number of articles, date (year) of publication, total citations, value of the h-index, document types, countries of publication, journal names, collaboration patterns and institutions. A total of 594 articles were retrieved from Scopus database for the period of 1955-2015. The percentage share of global intravenous lipid emulsion research output showed that research output was 85.86% in 2006-2015 with yearly average growth in this field of 51 articles per year. The USA, United Kingdom (UK), France, Canada, New Zealand, Germany, Australia, China, Turkey and Japan accounted for 449 (75.6%) of all the publications. The total number of citations for all documents was 9,333, with an average of 15.7 citations per document. The h-index of the retrieved documents for lipid emulsion research as antidote for the treatment of acute poisoning was 49. The USA and the UK achieved the highest h-indices, 34 and 14, respectively. New Zealand produced the greatest number of documents with international collaboration (51.9%) followed by Australia (50%) and Canada (41.4%) out of the total number of publications for each country. In summary, we found an increase in the number of publications in the field of lipid emulsion after 2006. The results of this study demonstrate that the majority of publications in the field of lipid emulsion were published by high-income countries. Researchers from

    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.

    Background and purpose: To investigate the feasibility of using intravenous contrast-enhanced computed tomography (CT) scans in 3-dimensional conformal radiotherapy (3D-CRT), stereotactic body radiation therapy (SBRT) and intensity-modulated radiotherapy (IMRT) treatment planning for lung cancers, respectively. Materials and methods: Twelve patients with bulky lung tumors and 14 patients with small lung tumors were retrospectively analyzed. Each patient took two sets of CT in the same position with active breathing control (ABC) technique before and after intravenous contrast agent (CA) injections. Bulky tumors were planned with 3D-CRT, while SBRT plans were generated for patients with small tumors based on CT scans with intravenous CA. In addition, IMRT plans were generated for patients with bulky tumors to continue on a planning study. All plans were copied and replaced on the scans without intravenous CA. The radiation doses calculated from the two sets of CTs were compared with regard to planning volumes (PTV), the organ at-risk (OAR) and the lungs using Wilcoxon's signed rank test. Results: In comparisons for 3D-CRT plans, CT scans with intravenous CA reduced the mean dose and the maximum dose of PTV with significant differences (p 95 ) for targets, respectively (p < 0.05). There was no statistical significance for lung parameters between two sets of scans in SBRT plans and IMRT plans. Conclusions: The enhanced CT scans can be used for both target delineation and treatment planning in 3D-CRT. The dose difference caused by intravenous CA is small. But for SBRT and IMRT, the minimum irradiation dose in targets may be estimated to be increased up to 2.71% while the maximum dose may be estimated to be decreased up to 1.36%. However, the difference in dose distribution in most cases were found to be clinical tolerable.

    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.

    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

    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 ).

    Full Text Available Recombinant tissue plasminogen activator (rTPA is one of the main portions of acute ischemic stroke management, but unfortunately has some complications. Myocardial infarction (MI is a hazardous complication of administration of intravenous rTPA that has been reported recently. A 78-year-old lady was admitted for elective coronary artery bypass graft surgery. On the second day of admission, she developed acute left hemiparesis and intravenous rTPA was administered within 120 minutes. Three hours later, she has had chest pain. Rescue percutaneous coronary intervention was performed on right coronary artery due to diagnosis of inferior MI, and the symptoms were resolved.

    Full Text Available Introduction. During the last few years, intravenous lipid emulsions have been effectively used in treatment of acute poisonings with lipophilic substances, including verapamil. Case report. A 37-year-old women presented 1 hour after ingestion of 2.8 g verapamil with hypotension and complete heart block. Because of the applied standard therapy failure and further patients impairment, Intralipid® 20% was used. Sinus rhythm was restored, arterial blood pressure increased and verapamile concentrations, both total and free decreased. Conclusion. Intravenous lipid emulsion can be important in treatment of severe acute intoxication and cardiotoxicity caused by verapamil.

    1993-01-01

    A blind, comparative clinical study was performed prospectively to examine the correlation between image quality of CT scan in terms of contrast enhancement effect and amount of intravenous contrast media. A total of 357 patients were randomized into two groups. Ionic high-osmolality contrast media (68% meglumine ioglicate) was administered intravenously as 100 ml bolus in one group and as 50 ml bolus in the other group. Statistically significant differences of image quality were found in CT scans of the brain, head and neck, chest and abdomen (p 0.05). We suggest that amount of contrast media may be reduced in pelvis CT without significant degradation of image quality

  6. Relative Incidence of Phlebitis Caused by Continuous Intravenous Infusion of Cephapirin and Cephalothin

    1972-01-01

    In a single-blinded study, two groups of 10 healthy subjects were given cephapirin or cephalothin by continuous intravenous infusion for 5 days, 0.5 g every 6 hr for the first day and then 1.0 g every 6 hr for 4 days. Eight of the cephalothin subjects and two of the cephapirin subjects developed phlebitis. Phlebitis was more severe in the cephalothin group and developed more rapidly, necessitating vein changes six times more often than in the cephapirin group. The less irritating properties of cephapirin demonstrated in this study indicate it may be the more useful cephalosporin analogue for intravenous therapy. PMID:4790563

    Full Text Available We report the clinical details and imaging findings of a case of transient angioedema of the small bowel following intravenous administration of non-ionic iodinated contrast material in a 17 year old female with no predisposing risk factors. Findings included long segment, symmetric, circumferential, low-density, bowel wall thickening involving the duodenum, jejunum, and most of the ileum on computed tomography scan obtained at 7 min following intravenous contrast material injection. This entity is self-limiting with a favourable clinical outcome and requires no specific treatment but only aggressive clinical monitoring.

    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.

    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.

  11. Adverse Effects with Ambulatory Intravenous Immunoglobulin Administration in Adult Patients with Common Variable Immunodeficiency

    Directory of Open Access Journals (Sweden)

    Karen Alicia Rodríguez-Mireles

    2014-06-01

    Full Text Available Background: Common variable immunode ciency (CVID is the most frequent symptomatic primary immunodeficiency, affecting 1:25,000- 75,000 people. It is characterized by the absence or decrease antibody production. Treatment for CVID consists on human immunoglobulin administration, and the intravenous route is the most common route for administration, at 400-800 mg/kg of weight every 3-4 weeks. Adverse effects associated with intravenous immunoglobulin (IVIg use occur in 25% of all infusions, with severe adverse reactions presenting in less than 1% of all patients. Acute renal failure can occur as a severe adverse reaction, which presents 1-10 days after starting IVIg treatment. In our center we implemented an ambulatory scheme for IVIg administration, which allows its administration in an average of 3 hours, without severe adverse effects. Objectives: To describe adverse effects and to evaluate the frequency of renal failure secondary to ambulatory IVIg administration in patients with common variable immunode ciency. Material and method: A descriptive and prospective study was done including adult patients con de nitive diagnosis of common variable immunodeficiency, receiving IVIg at replacement dose every 3 weeks. All patients were evaluated with clinical exploration, somatometry, serum creatinine, albumin and urea determination, 24 hours creatinine clearance, glomerular ltration rate with CKD-EPI, and immediate renal function associated with accumulated IVIg. Results were analyzed with descriptive statistics. Results: We determined adverse effects in 25 patients with common variable immunode ciency (15 women and 10 men, average age 36.7 years, during a 10 months period (January-September 2013. During this period 284 IVIg infusions were administered using our scheme, frequency of adverse effects were 12.9%, with 5.2% of early adverse effects and 7.7% late adverse effects, all being mild to moderate, in some cases required analgesic and

    Coagulation factors (II, VII, IX, X, and particularly XIa) remaining in high concentrations in intravenous immunoglobulin (IVIG) preparations can form thrombi, causing thromboembolic events, and in serious cases, result in death. Therefore, manufacturers of biological products must investigate the ability of their production processes to remove procoagulant activities. Previously, we were able to remove coagulation factors II, VII, IX, and X from our IVIG preparation through ethanol precipitation, but factor XIa, which plays an important role in thrombosis, remained in the intermediate products. Here, we used a chromatographic process using a new resin that binds with high capacity to IgG and removes procoagulant activities. The procoagulant activities were reduced to low levels as determined by the thrombin generation assay: 250 s, FXI/FXIa ELISA: <0.31 ng/mL. Even after spiking with FXIa at a concentration 32.5 times higher than the concentration in normal specimens, the procoagulant activities were below the detection limit (<0.31 ng/mL). These results demonstrate the ability of our manufacturing process to remove procoagulant activities to below the detection limit (except by NaPTT), suggesting a reduced risk of thromboembolic events that maybe potentially caused by our IVIG preparation.

    A new human liquid intravenous immunoglobulin product, Flebogamma DIF, has been developed. This IgG is purified from human plasma by cold ethanol fractionation, PEG precipitation and ion exchange chromatography. The manufacturing process includes three different specific pathogen clearance (inactivation/removal) steps: pasteurization, solvent/detergent treatment and Planova nanofiltration with a pore size of 20 nm. This study evaluates the pathogen clearance capacity of seven steps in the production process for a wide range of viruses through spiking experiments: the three specific steps mentioned above and also four more production steps. Infectivity of samples was measured using a Tissue Culture Infectious Dose assay (log(10) TCID(50)) or Plaque Forming Units assay (log(10) PFU). Validation studies demonstrated that each specific step cleared more than 4 log(10) for all viruses assayed. An overall viral clearance between > or =13.33 log(10) and > or =25.21 log(10), was achieved depending on the virus and the number of steps studied for each virus. It can be concluded that Flebogamma DIF has a very high viral safety profile. 2010 The International Association for Biologicals. Published by Elsevier Ltd. All rights reserved.

    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

    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

    The concentration of Al in 4 lots of 5% Albumina and in 14 lots of 5% immunoglobulins were estimated by adsorptive stripping voltammetric method. Mean Al concentrations amounted to 142.6 micrograms/l in 5% Albumina and to 202 micrograms/l in IVIG preparations produced in Poland. Al concentrations in foreign IVIG preparations ranged from 14 to 54 micrograms/l. These data show the need to consider setting an upper limit of microgram Al/l in i.v. drug products produced or registered in Poland.

    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.

    Conclusion: Our results suggest that coinfection with hepatitis C was common in intravenous drug users with IE, and that molecular patterns of MRSA isolates had high similarity. SCCmec type III, which is usually hospital-acquired, could have caused the community-associated MRSA endocarditis in our patients.

  1. INTRAVENOUS REGIONAL ANTIBIOTIC PERFUSION THERAPY AS AN ADJUNCTIVE TREATMENT FOR DIGITAL LESIONS IN SEABIRDS.

    Fiorello, Christine V

    2017-03-01

    Foot infections are a common problem among seabirds in wildlife rehabilitation. Pododermatitis and digital infections are often challenging to treat because of the presence of suboptimal substrates, abnormal weight-bearing due to injuries, and suboptimal nutritional or health status. Seabirds represent the majority of animals requiring rehabilitation after oil spills, and foot problems are a common reason for euthanasia among these birds. Antibiotic intravenous regional perfusion therapy is frequently used in humans and other species to treat infections of the distal extremities, but it has not been evaluated in seabirds. During the 2015 Refugio oil spill response, four birds with foot lesions (pododermatitis, osteomyelitis, or both) were treated with ampicillin/sulbactam administered intravenously to the affected limb(s) in addition to systemic antibiotics and anti-inflammatories. Three of the birds, all brown pelicans ( Pelecanus occidentalis ) recovered rapidly and were released. Two of these birds had acute pododermatitis and were treated once with intravenous regional perfusion. They were released approximately 3 wk after the perfusion therapy. The third pelican had osteomyelitis of a digit. It was treated twice with intravenous regional perfusion and was released about 1 mo after the initial perfusion therapy. The fourth bird, a Pacific loon ( Gavia pacifica ), was treated once with perfusion therapy but did not respond to treatment and was euthanatized. No serious adverse effects were observed. This technique should be explored further in avian species.

Despite its frequent use, little is known about its efficacy and pharmacokinetics (PK) when intravenously administered in the critically ill patient. A previous study suggests that therapeutic concentrations are not

    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.

    Conclusions and importance: An iris abscess is a rare clinical presentation of intravenous drug use-associated endogenous endophthalmitis and as a result may present a diagnostic challenge as it requires a high level of clinical suspicion and a detailed social history to elicit the drug abuse. Early diagnosis and aggressive therapy is the key to better visual outcomes in these patients.

    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.

    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.

    We have reported that administration of the phosphodiesterase III inhibitor milrinone increases renin secretion in conscious rabbits. The aim of the present study was to determine if the increase in renin secretion results from a direct renal action of milrinone, or from an indirect extrarenal effect of the drug. This was accomplished by comparing the effects of intrarenal and intravenous infusion of graded doses of milrinone on plasma renin activity in unilaterally nephrectomized conscious rabbits. Milrinone was infused into the renal artery in doses of 0.01, 0.1 and 1.0 micro-g/kg/min, and intravenously in the same rabbits in doses of 0.01, 0.1, 1.0 and 10 micro-g/kg/min. Each dose was infused for 15 min. No intrarenal dose of milrinone altered plasma renin activity or arterial pressure, although at the highest dose, there was a small increase in heart rate. Intravenous infusion of milrinone at 1.0 micro-g/kg/min increased plasma renin activity to 176 +/- 55% of the control value (P less than 0.05). Heart rate increased but arterial pressure did not change. Intravenous infusion of milrinone at 1O micro-g/kg/min increased plasma renin activity to 386 +/- 193% of control in association with a decrease in arterial pressure and an increase in heart rate. These results confirm that milrinone increases renin secretion, and indicate that the stimulation is due to an extrarenal effect of the drug.

    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.

    In preterm infants, both hypo- and hyperglycemia are a frequent problem. Intravenous lipids can affect glucose metabolism by stimulation of gluconeogenesis by providing glycerol, which is a gluconeogenic precursor, and/or free fatty acids (FFA), which are stimulants of the rate of gluconeogenesis.

    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

    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.

    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.

    Full Text Available To analyse the association in newborns between blood levels of phenylalanine and feeding method and gestational age.This observational, cross-sectional study included a sample of 11,829 infants between 2008 and 2013 in a Spanish region. Data were recorded on phenylalanine values, feeding method [breast, formula, mixed (breast plus formula, or partial or fully intravenous feeding], gestational age in weeks (<32, 32-37, ≥37, gender and days since birth at the moment of blood collection. Outcomes were [phenylalanine] and [phenylalanine] ≥95th percentile. Associations were analysed using multivariate models [linear (means difference and logistic regression (adjusted odds ratios].Higher phenylalanine values were associated with lower gestational age (p<0.001 and with intravenous feeding (p<0.001.The degree of prematurity and intravenous feeding influenced the plasma concentration of phenylalanine in the newborn. Caution should be taken in [phenylalanine] for newborns with intravenous feeding, monitoring them carefully. Very preterm infants given the recommended amount of amino acids should also be strictly monitored. These findings should be taken into consideration and call for adapting the amounts to the needs of the infant.

    Infective endocarditis is a life threatening complication of intravenous drug abuse, which continues to be a major burden with inadequately characterised long-term outcomes. We reviewed our institutional experience of surgical treatment of infective endocarditis in active intravenous drug abusers with the aim of identifying the determinants long-term outcome of this distinct subgroup of infective endocarditis patients. A total of 451 patients underwent surgery for infective endocarditis between January 1993 and July 2013 at the University Hospital of Heidelberg. Of these patients, 20 (7 female, mean age 35 ± 7.7 years) underwent surgery for infective endocarditis with a history of active intravenous drug abuse. Mean follow-up was 2504 ± 1842 days. Staphylococcus aureus was the most common pathogen detected in preoperative blood cultures. Two patients (10%) died before postoperative day 30. Survival at 1, 5 and 10 years was 90%, 85% and 85%, respectively. Freedom from reoperation was 100%. Higher NYHA functional class, higher EuroSCORE II, HIV infection, longer operating time, postoperative fever and higher requirement for red blood cell transfusion were associated with 90-day mortality. In active intravenous drug abusers, surgical treatment for infective endocarditis should be performed as extensively as possible and be followed by an aggressive postoperative antibiotic therapy to avoid high mortality. Early surgical intervention is advisable in patients with precipitous cardiac deterioration and under conditions of staphylococcal endocarditis. However, larger studies are necessary to confirm our preliminary results.

    To evaluate the efficacy and limitation of intra-arterial urokinase (IAUK) infusion for treatment of acute cerebral stroke. Twenty-seven acute cerebral stroke patients treated with IAUK infusion within six hours of stroke onset were reviewed. All patients showed normal initial brain findings on CT. In 21 patients, urokinase(5-15 x 10 5 IU) was administered through a microcatheter placed into or proximal to occluded segment. Mechanical disruption of thrombus by guidewire was performed in 17 patients. Angiographic and clinical responses and complications after IAUK infusion, were evaluated and the results were compared with those of intravenous heparin(N=19) and urokinase infusion(N=19). Complete or partial angiographic recanalization of occluded segment was found in 18 patients (67%), and neurologic improvement was followed in 14 patients(52%). The degree of improvement on the stroke scale score after IAUK infusion was statistically more significant(p<0.05) than that shown after intravenous heparin and urokinase infusion. Complications after IAUK infusion were large(15%) and small amount intracerebral hemorrhage(15%), contrast leakage into brain parenchyma(11%), and gastrointestinal bleeding(4%). Between the IAVK and the intravenous urokinase infusion group, differences in extent and types of complications were statistically insignificant, but were significantly higher in those two groups than in the intravenous heparin infusion group. IAUK infusion may be effective for the treatment of acute cerebral stroke

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.

    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.

    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.

  7. Intraosseous Administration of Antidotes in the Chemical Weapons Victim - An Alternative to the Intravenous Route

    Hazardous materials paradigms call for definitive treatment of chemical victims to begin in the 'warm zone' during decontamination. This delay may result in lethal outcomes, particularly in the case of multiple victims, where rescue may be delayed due to insufficient numbers of rescue teams. It is virtually impossible for rescuers in full protective gear to establish intravenous lines. In recent years, significant advances have been made in intraosseous (IO) infusion devices. An IO device developed in our institution, the EZ-IO, is very easily placed by rescuers in typical work uniforms. IO placement takes longer while in protective gear, but is feasible. The IO is equivalent to an intravenous line, allowing more rapid administration of antidotes in the event of chemical mass casualties. Antidotes not amenable to intramuscular administration and even those often given IM may be more effective given IO. IO administration has the following possible advantages over intravenous or intramuscular antidote administration: 1. Drugs administered IO reach the vascular system virtually instantaneously. 2. IO administration may be performed in protective clothing and could theoretically be employed while awaiting rescue. 3. IO administration may be preferred over intravenous administration in the warm zone. In summary, IO administration of antidotes should be further evaluated for use in chemical disasters. The ease and speed of placement, ready access to the vascular tree, and potential for earlier intervention make it a potentially ideal means of vascular access and antidotal administration in the mass casualty situation.

    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.

    2009-06-01

    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

    A ketogenic diet has been used successfully to treat intractable epilepsy. However, the role of early intravenous initiation of ketogenic diet in the acute phase of super-refractory status epilepticus is not well-described. An intravenous ketogenic diet was administered to a boy with super-refractory status epilepticus. At 24 hours after intravenous ketogenic diet, moderate ketosis appeared, and thiamylal was successfully weaned at 70 hours after admission. An intravenous ketogenic regimen led to subsequent ketosis and seizure control in a child with super-refractory status epilepticus. Early induction of ketosis may be a novel strategy to effectively treat super-refractory status epilepticus. Although there are few data regarding the early use of intravenous ketogenic diet in the treatment of super-refractory status epilepticus, it may be considered an alternative option.

    We sought to analyze whether maternal intravenous fluid therapy prior to external cephalic version (ECV) increases the amount of amniotic fluid and the success rate of the procedure. This was a prospective single-center cohort study of 200 women with a consecutive cohort of 100 pregnant women with a breech presentation at term who were administered intravenous fluid therapy with 2 L of hypotonic saline before the version attempt, compared to a control cohort of 100 pregnant women not given hydration treatment. The mean increase in the amniotic fluid index (AFI) after intravenous maternal hydration was 3.75 ± 2.71 cm. The amount of fluid before hydration was the only variable found to be associated with increases in amniotic fluid levels, both in absolute and relative terms (odds ratio, -0.21; 95% confidence interval, -0.37 to -0.05 and odds ratio, -4.62; 95% confidence interval, -6.17 to -3.06; P < .01, respectively). We did not observe any severe complications secondary to the intravenous fluid therapy. The ECV success rate was 43% in the study group compared to 47% in the control group (P = .67). The success rate was significantly lower the larger the relative increase in the AFI, although no correlation was found in absolute terms (χ(2) for linear trend = 0.03 and 0.34, respectively). Maternal intravenous fluid therapy with 2 L of hypotonic saline prior to ECV is an effective and safe technique for increasing the AFI. However, its use in ECV does not increase the success rate of the procedure. Copyright © 2014 Elsevier Inc. All rights reserved.

    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.

    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.

  1. Rapid Inpatient Titration of Intravenous Treprostinil for Pulmonary Arterial Hypertension: Safe and Tolerable.

    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.

    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.

  3. Epidural versus intravenous fentanyl for postoperative analgesia following orthopedic surgery: randomized controlled trial

    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.

    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

    In all cases of severe dehydration from diarrhea, WHO recommends rapid rehydration. If oral rehydration in children is contraindicated, intravenous rehydration is recommended for immediate administration. However, methods of intravenous rehydration appear to be inadequately addressed in the medical schools of Colombia. Current approaches to oral rehydration were summarized, and instructors were informed concerning current WHO recommendations. A survey was designed for pediatric instructors in Colombian medical schools. Direct questions about rehydration methods were included as well as presentation of theoretical clinical situations with dehydrated children. The survey also asked for the conditions necessary for intravenous rehydration and method of administration (volume, solution, concentration and speed of infusion). Forty-one surveys were included (82% of medical schools in Colombia). Inadequate contraindications for oral rehydration therapy were made in 41%. Rapid and slow intravenous rehydration was recommended in 71% and 29%, respectively; 57% recommended fluid bolus to rehydrate. Adequate volumes were recommended by less than half of the respondents and adequate sodium concentration was recommended by 85%. In 56% of medical schools, glucose was not included in solutions and 66% use Ringer lactate. Normal saline solution, dextrose solution with electrolytes and polyelectrolytes solutions are also used. Misconceptions are common concerning the contraindications to oral rehydration therapy. One-third of medical schools promote a slow therapy despite the superiority of the rapid therapy. Uniformity for rapid therapy schemes is lacking. Bolus rehydration is commonly advocated despite the fact that this method is unsupported by the literature. Concepts about rehydration must be updated in medical schools and a national guide for intravenous rehydration is recommended.

    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 The purpose of the present study was to identify noninvasive methods to evaluate the severity of iron overload in transfusion-dependent ß-thalassemia and the efficiency of intensive intravenous therapy as an additional tool for the treatment of iron-overloaded patients. Iron overload was evaluated for 26 ß-thalassemia homozygous patients, and 14 of them were submitted to intensive chelation therapy with high doses of intravenous deferoxamine (DF. Patients were classified into six groups of increasing clinical severity and were divided into compliant and non-compliant patients depending on their adherence to chronic chelation treatment. Several methods were used as indicators of iron overload. Total gain of transfusion iron, plasma ferritin, and urinary iron excretion in response to 20 to 60 mg/day subcutaneous DF for 8 to 12 h daily are useful to identify iron overload; however, urinary iron excretion in response to 9 g intravenous DF over 24 h and the increase of urinary iron excretion induced by high doses of the chelator are more reliable to identify different degrees of iron overload because of their correlation with the clinical grades of secondary hemochromatosis and the significant differences observed between the groups of compliant and non-compliant patients. Finally, the use of 3-9 g intravenous DF for 6-12 days led to a urinary iron excretion corresponding to 4.1 to 22.4% of the annual transfusion iron gain. Therefore, continuous intravenous DF at high doses may be an additional treatment for these patients, as a complement to the regular subcutaneous infusion at home, but requires individual planning and close monitoring of adverse reactions.

    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

    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.

    This study supports the existing literature and suggests that the use of IV Tranexamic acid alone or in combination with intra-articular dose in TKA may reduce the requirement for transfusion (Level IV evidence. Furthermore, this study suggests that the use of tranexamic acid as a combination of Intravenous and intra-articular administration has no effect on range of motion, or medical complications during hospital stay. Although it was not a statistically significant finding, our study suggested a trend towards a greater reduction in haemoglobin and haematocrit fall in the combination therapy group when compared to IV Tranexamic acid alone

  11. Intravenous Alteplase for Acute Ischemic Stroke in Taiwan: Can We Expand the National Health Insurance's Reimbursement Criteria?

    Hsieh, Cheng-Yang

    2017-03-15

    lization of intravenous thrombolysis with alteplase was very low in Taiwanese patients with acute ischemic stroke(1). One of the reasons is the strict reimbursement guideline made by the Bureau of National Health Insurance (NHI) in 2004(2). In this issue of the Acta Neurologica Taiwanica, Yu-Hsiang Su and co-authors(3) retrospectively evaluated outcomes of their thrombolysed stroke patients who were "mismatched" between updated clinical practice guideline and NHI reimbursement criteria. They concluded that the outcomes of patients treated according to guidelines were comparable between the reimbursement and non-reimbursement groups. Despite the inherent selection bias and no comparison with the non-treated patients in this observational study, it might serve the an important local evidence for physicians in Taiwan when evaluating intravenous thrombolysis for acute ischemic stroke. SO, CAN WE EXPAND THE REIMBURSEMENT CRITERIA FOR INTRAVENOUS ALTEPLASE IN STROKE PATIENTS? At the present time, the answer may still probably be NO! The insurance payer, usually after an economic evaluation, may decide to pay a pharmaceutical product for its beneficiaries. As a rule of thumb, insurance reimbursement criteria should not be greater than the labelled prescribing information. Thus, the essence of this question should be back to the labelled indications and contraindications of alteplase for stroke, made by Taiwanese regulator in Nov 2002(4). Although data from high-quality meta-analyses(5,6) of new trials in the past decade challenged some of the major contraindications, such as onset > 3 hours or age > 80 years, the Taiwan's Food and Drug Administration has turned down twice the application by the manufacturer to change the package insert regarding those two contraindications. The reasons were mostly "insufficient of benefits". Without the change of labelled prescribing information, the NHI reimbursement criteria cannot be expanded. WHAT CAN WE DO NOW? Pragmatically

    Increasing the dietary fat content of ruminant diets decreases methane (CH 4 ) production. This effect is caused by the toxic properties of fatty acids on rumen microbial populations, coating of feed particles diminishing the accessibility for microbes, and a reduction in dry matter intake (DMI). The latter effect is caused by postabsorptive long-chain fatty acids eliciting anorexic signaling; however, whether circulating long-chain fatty acids affect rumen CH 4 production alike is unknown. To approach this question, 5 rumen-cannulated Holstein cows in late lactation received 2 jugular catheters and were kept in respiration chambers to measure CH 4 production and DMI for 48 h. In a crossover design, cows were intravenously infused with a 20% lipid emulsion (LIPO) or 0.9% NaCl (CON). The LIPO cows received 2.1 kg of triglycerides/d [0.152 ± 0.007 g of triglycerides/(kg of BW × h) -1 ] consisting of 12.1% palmitic acid, 4.2% stearic acid, 31.1% oleic acid, and 52.7% linoleic acid. Blood and rumen fluid samples were taken hourly during the day. Results showed that LIPO compared with CON infusion increased plasma triglyceride as well as free fatty acid and serotonin concentrations but reduced the proportion of de novo synthesized milk fatty acids (sum of C6 to C16). Daily CH 4 production and DMI were lower, whereas daily CH 4 yield (CH 4 /DMI) was greater in LIPO than CON cows, although CH 4 yield decreased from d 1 to d 2 by 2 to 14% in LIPO-infused cows only. This effect was associated with a higher (acetate + butyrate)/propionate ratio, tending lower propionate concentrations between 24 and 34 h of infusion, reduced relative abundances of genera belonging to Succinivibrio, Ruminococcaceae, and Ruminiclostridium, and greater relative Bacteroidetes genus abundances in the rumen.

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

    Directory of Open Access Journals (Sweden)

    Luis Prats-Sanchez

    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.

    Full Text Available Purpose:Renal transplantation significantly improves quality of life compared to hemodialysis in patients with end-stage renal failure. In end-stage renal failure anesthetic technique should be planned carefully, due to changes in volume distribution, drug metabolism, excretion. Results of total intravenous anesthesia, inhalation anesthesia, regional techniques are being investigated. Aim of this study was to present our experience in total intravenous anesthesia in 77 patients, who underwent live and cadaveric donor renal transplantation at Baskent University Faculty of Medicine Adana Teaching and Research Center. Material and Methods:Induction of anesthesia was performed with propofol(2mg/kg and fentanyl(1μg/kg, and rocuronium bromide(0.4-0.5mg/kg was given before intubation. Anesthesia was maintained with total intravenous anesthesia(propofol,50 mcg/kg/min; remifentanil,0.25 mcg/kg/min infusion. Intraoperative fluid, urine volumes were recorded.

    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.

    Aldosterone prevents the uptake of norepinephrine in the myocardium. Atrial natriuretic peptide (ANP), a circulating hormone of cardiac origin, inhibits aldosterone synthase gene expression in cultured cardiocytes. We evaluated the effects of intravenous ANP on cardiac sympathetic nerve activity (CSNA) and aldosterone suppression in patients with acute decompensated heart failure (ADHF). We studied 182 patients with moderate nonischemic ADHF requiring hospitalization and treated with standard therapy containing intravenous ANP and 10 age-matched normal control subjects. ANP was continuously infused for >96 h. In all subjects, delayed total defect score (TDS), heart to mediastinum ratio, and washout rate were determined by 123 I-metaiodobenzylguanidine (MIBG) scintigraphy. Left ventricular (LV) end-diastolic volume, end-systolic volume, and ejection fraction were determined by echocardiography. All patients with acute heart failure (AHF) were examined once within 3 days and then 4 weeks after admission, while the control subjects were examined only once (when their hemodynamics were normal). Moreover, for 62 AHF patients, plasma aldosterone concentrations were measured at admission and 1 h before stopping ANP infusion. 123 I-MIBG scintigraphic and echocardiographic parameters in normal subjects were more favorable than those in patients with AHF (all p < 0.001). After treatment, all these parameters improved significantly in AHF patients (all p < 0.001). We also found significant correlation between percent changes of TDS and aldosterone concentrations (r = 0.539, p < 0.001) in 62 AHF patients. The CSNA and LV performance were all improved in AHF patients. Furthermore, norepinephrine uptake of myocardium may be ameliorated by suppressing aldosterone production after standard treatment containing intravenous ANP. (orig.)

    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.

Methods Prospective study of the adverse effects of IV lignocaine in 106 patients with fibromyalgia; retrospective questionnaire study of the efficacy of IV lignocaine in 50 patients with fibromyalgia. Results Prospective study: Two major (pulmonary oedema and supraventricular tachycardia and 42 minor side-effects were reported. None had long-term sequelae. The commonest was hypotension (17 cases. Retrospective study: Pain and a range of psychosocial measures (on single 11-point scales improved significantly after treatment. There was no effect of the treatment on work status. The average duration of pain relief after the 6-day course of treatment was 11.5 ± 6.5 weeks. Conclusions Intravenous lignocaine appears to be both safe and of benefit in improving pain and quality of life for patients with fibromyalgia. This needs to be confirmed in prospective randomised controlled trials.

    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

    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.

    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.

Both drugs induced a decrease in serum alkaline phosphatase levels as well as the elimination of hydroxyproline from urine, an effect most marked in the group treated with pamidronate. The response was maintained for 6 months after the infusion in the majority of the patients. No relevant side effects were found, except post-infusion febricula and in one patient, self-limiting thrombopenia 6 months after the infusion. We conclude that the intravenous infusion of either of the two drugs may constitute a safe and effective alternative for treatment of PDB with marked biochemical activity or resistant to conventional therapy.

    The nonsteroidal antiinflammatory drug ketoprofen (KTP) is a commonly used antiinflammatory and analgesic agent in reptile medicine, but no studies documenting its pharmacokinetics in this species have been published. Ketoprofen was administered as a racemic mixture to green iguanas (Iguana iguana) intravenously (i.v.) and intramuscularly (i.m.) at 2 mg/kg. Pharmacokinetic analyses were performed and indicated that ketoprofen in iguanas administered by the intravenous route has a classical two-compartmental distribution pattern, a slow clearance (67 ml/ kg/hr) and a long terminal half-life (31 hr) compared to ketoprofen studies reported in mammals. When delivered by the intramuscular route, bioavailability was 78%. These data indicate the daily dosing that is generally recommended for reptile patients, as an extrapolation from mammalian data, may be more frequent than necessary.

    Full Text Available Mohamed Mahdi-Rogers, Yusuf A RajaballyNeuromuscular Clinic, Department of Neurology, University Hospitals of Leicester, Leicester, UKAbstract: Chronic inflammatory demyelinating polyneuropathy (CIDP is an acquired heterogeneous disorder of immune origin affecting the peripheral nerves, causing motor weakness and sensory symptoms and signs. The precise pathophysiology of CIDP remains uncertain although B and T cell mechanisms are believed to be implicated. Intravenous immunoglobulins (IVIg have been shown in a number of trials to be an effective treatment for CIDP. IVIg is thought to exert its immunomodulatory effects by affecting several components of the immune system including B-cells, T-cells, macrophages and complement. This article provides an overview of the pathogenesis of CIDP and of its treatment with IVIg.Keywords: chronic inflammatory demyelinating polyneuropathy, intravenous immunoglobulin, pathogenesis, treatment

    Full Text Available Ketamine, among wide variety of sedative drugs, has shown beneficial effects when using during the procedural sedation, specifically in pediatrics. Various parameters should be considered in order to perform a safe and effective procedural sedation including optimum dosage of the sedative, administration methods of sedation, and need for applying any adjuvant drug. In this study, we aimed to review the studies, which have compared the efficacy of the different ways of the injection of ketamine such as intravenous or intramuscular ketamine application. Based on data obtained from the related articles, efficacy and safety of these two methods of ketamine usage in the pediatric procedural sedation were widely similar, but the intravenously administration of the ketamine can be proposed as the preferable mode.

    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

    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.

    This report describes the occurrence of chest pain and electrocardiographic features of acute myocardial infarction following intravenous dipyridamole-handgrip stress. Myocardial perfusion imaging (Rb-82 PET) demonstrated a stress-induced perfusion defect. Following failure to respond to medical therapy, urgent cardiac catheterization demonstrated total occlusion of the left anterior descending coronary artery. The vessel was revascularized, with limitation of myocardial damage evidenced by failure to develop anterior Q waves and only modest elevation of cardiac enzyme levels. Complications of intravenous dipyridamole stress are rare, this case constituting the first major problem in over 500 such procedures at this institution. However, this experience demonstrates the importance of vigilant observation during the performance of this technique

    Treatment of children with intravenous ceftriaxone on an ambulatory basis is described. This allows a child to remain at home, but also be reviewed regularly when attending the Emergency Department for antibiotics. Indications for, and length of, treatment and laboratory parameters were recorded. Also, a survey of children's parents was undertaken to ascertain opinions regarding ambulatory treatment. 36 patients were treated with ambulatory ceftriaxone over 4 months. Indications included fever without focus, tonsillitis, periorbital cellulitis, urinary tract infection, petechial rash and lymphadenitis. Median duration of treatment was 2.3 days. There was no occult bacteraemia but five positive urine cultures. There was one failure of treatment with subsequent admission for alternative intravenous antibiotics. Parental opinion favours ambulatory treatment, with 94% of parents acknowledging they would choose it again in similar circumstances. Cost analysis favours ambulatory treatment based on predicted costs of a similar length of inpatient stay.

    Full Text Available Nonparaneoplastic opsoclonus–myoclonus ataxia syndrome is a rare neuroinflammatory condition featured by opsoclonus, myoclonus, ataxia, and cognitive behavioral disturbance. The authors report an observation of enterovirus 71-associated opsoclonus–myoclonus ataxia syndrome evolving toward full recovery on intravenous intravenous immunoglobulin (IG treatment. Based on this case report, enterovirus 71 should be added to the list of infectious agents likely involved in opsoclonus–myoclonus ataxia syndrome, including the emerging subgroup of opsoclonus–myoclonus ataxia syndrome recovering without aggressive or prolonged immunosuppressive intervention. Further studies are mandatory to define the precise role, incidence, treatment, and outcome of enterovirus 71 and other infectious agents in benign forms of opsoclonus–myoclonus ataxia syndrome.

    Little is known about the effects of intravenous abuse of cocaine, especially on the inner ear. We report on a 26-year-old man who presented to our outpatient department with a sudden severe hearing loss after intravenous injection of cocaine. The audiogram on admission showed symmetric air conduction levels up to 80 dB at 4 kHz. After treatment with intravenous sodium chloride, prednisolone, and pentoxifylline, the audiogram 2 days later showed a bilateral normacusis. A review of the literature on the topic is given and possible reasons for inner ear damages caused by cocaine are discussed.

    Full Text Available Some diabetic foot ulcers, which are notoriously difficult to cure, are one of the most common health problems in diabetic patients .There are several surgical and medical options which already have been introduced for treatment of diabetic foot ulcers, so some patient will require amputation. The purpose of this study was to evaluate the efficacy of intravenous Semelil (ANGIPARSTM, a naive herbal extract to accelerate healing of diabetic foot ulcers. A multi-centric randomized controlled trial was conducted to evaluate intravenous Semelil for healing of diabetic foot ulcers. Sixteen diabetic patients were treated with intravenous Semelil, and nine other patients were treated with placebo as control group. Both groups were otherwise treated by wound debridement and irrigation with normal saline solution, systemic antibiotic therapy and daily wound dressing. Before and after intervention, the foot ulcer surface area was measured, by digital photography, mapping and planimetry. After 4 weeks, the mean foot ulcer surface area decreased from 479.93±379.75 mm2 to 198.93±143.75 mm2 in the intervention group (p = 0.000 and from 766.22±960.50 mm2 to 689.11±846.74 mm2 in the control group (p = 0.076. Average wound closure in the treatment group was significantly greater than placebo group (64% vs. 25%, p= 0.015. This herbal extract by intravenous rout in combination with conventional therapy is more effective than conventional therapy by itself probably without side effect. However, further studies are required in the future to confirm these results in larger population.

    Full Text Available Abstract Background Gastrointestinal bleeding is a common problem and its most common etiology is peptic ulcer disease. Ulcer rebleeding is considered a perilous complication for patients. To reduce the rate of rebleeding and to fasten the improvement of patients' general conditions, most emergency departments in Iran use H2-blockers before endoscopic procedures (i.e. intravenous omeprazole is not available in Iran. The aim of this study was to compare therapeutic effects of oral omeprazole and intravenous cimetidine on reducing rebleeding rates, duration of hospitalization, and the need for blood transfusion in duodenal ulcer patients. Methods In this clinical trial, 80 patients with upper gastrointestinal bleeding due to duodenal peptic ulcer and endoscopic evidence of rebleeding referring to emergency departments of Imam and Sina hospitals in Tabriz, Iran were randomly assigned to two equal groups; one was treated with intravenous cimetidine 800 mg per day and the other, with 40 mg oral omeprazole per day. Results No statistically significant difference was found between cimetidine and omeprazole groups in regards to sex, age, alcohol consumption, cigarette smoking, NSAID consumption, endoscopic evidence of rebleeding, mean hemoglobin and mean BUN levels on admission, duration of hospitalization and the mean time of rebleeding. However, the need for blood transfusion was much lower in omeprazole than in cimetidine group (mean: 1.68 versus 3.58 units, respectively; p Conclusion This study demonstrated that oral omeprazole significantly excels intravenous cimetidine in reducing the need for blood transfusion and lowering rebleeding rates in patients with upper gastrointestinal bleeding. Though not statistically significant (p = 0.074, shorter periods of hospitalization were found for omeprazole group which merits consideration for cost minimization.

    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.

    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.

    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.

    Full Text Available The aim of the present study was to describe the plasma pharmacokinetic profile and skin concentrations of lincomycin after intravenous administration of a 15% solution and oral administration of 300 mg tablets at a dosing rate of 15 mg/kg to cats. Susceptibility of staphylococci (n = 31 and streptococci (n = 23 strains isolated from clinical cases was also determined. Lincomycin plasma and skin concentrations were determined by microbiological assay using Kocuria rhizophila ATCC 9341 as test microorganism. Susceptibility was established by the antimicrobial disc diffusion test. Individual lincomycin plasma concentration–time curves were analysed by a non-compartmental approach. After intravenous administration, volume of distribution, body clearance and elimination half-life were 0.97 L/kg ± 0.15 L/kg, 0.17 L/kg ± 0.06 L/h.kg and 4.20 h ± 1.12 h, respectively. After oral administration, peak plasma concentration, time of maximum plasma concentration and bioavailability were 22.52 µg/mL ± 10.97 µg/mL, 0.80 h ± 0.11 h and 81.78% ± 24.05%, respectively. Two hours after lincomycin administration, skin concentrations were 17.26 µg/mL ± 1.32 µg/mL (intravenous and 16.58 µg/mL ± 0.90 µg/mL (oral. The corresponding skin: plasma ratios were 2.08 ± 0.47 (intravenous and 1.84 ± 0.97 (oral. The majority of staphylococci and streptococci tested in this study were susceptible to lincosamides (87.09% and 69.56%, respectively. In conclusion, lincomycin administered orally at the assayed dose showed a good pharmacokinetic profile, with a long elimination half-life and effective skin concentration. Therefore, it could be a good first option for treating skin infections in cats.

  9. Intravenous rehydration of malnourished children with acute gastroenteritis and severe dehydration: A systematic review.

    Houston, Kirsty A; Gibb, Jack G; Maitland, Kathryn

    2017-01-01

    Background: Rehydration strategies in children with severe acute malnutrition (SAM) and severe dehydration are extremely cautious. The World Health Organization (WHO) SAM guidelines advise strongly against intravenous fluids unless the child is shocked or severely dehydrated and unable to tolerate oral fluids. Otherwise, guidelines recommend oral or nasogastric rehydration using low sodium oral rehydration solutions. There is limited evidence to support these recommendations. Methods: We conducted a systematic review of randomised controlled trials (RCTs) and observational studies on 15 th June 2017 comparing different strategies of rehydration therapy in children with acute gastroenteritis and severe dehydration, specifically relating to intravenous rehydration, using standard search terms. Two authors assessed papers for inclusion. The primary endpoint was evidence of fluid overload. Results: Four studies were identified, all published in English, including 883 children, all of which were conducted in low resource settings. Two were randomised controlled trials and two observational cohort studies, one incorporated assessment of myocardial and haemodynamic function. There was no evidence of fluid overload or other fluid-related adverse events, including children managed on more liberal rehydration protocols. Mortality was high overall, and particularly in children with shock managed on WHO recommendations (day-28 mortality 82%). There was no difference in safety outcomes when different rates of intravenous rehydration were compared. Conclusions: The current 'strong recommendations' for conservative rehydration of children with SAM are not based on emerging evidence. We found no clinical trials providing a direct assessment of the current WHO guidelines, and those that were available suggested that these children have a high mortality and remain fluid depleted on current therapy. Recent studies have reported no evidence of fluid overload or heart failure with more

The carbohydrate shell for each of these preparations is unique and is key in determining the various physicochemical properties, the metabolic pathway, and the immunogenicity of the iron-carbohydrate complex. As intravenous dextran can cause severe, antibody-mediated dextran-induced anaphylactic reactions (DIAR), the purpose of this study was to explore the potential of various intravenous iron preparations, non-dextran-based or dextran/dextran-based, to induce these reactions. An IgG-isotype mouse monoclonal anti-dextran antibody (5E7H3) and an enzyme-linked immunosorbent assay (ELISA) were developed to investigate the dextran antigenicity of low molecular weight iron dextran, ferumoxytol, iron isomaltoside 1000, ferric gluconate, iron sucrose and ferric carboxymaltose, as well as isomaltoside 1000, the isolated carbohydrate component of iron isomaltoside 1000. Low molecular weight iron dextran, as well as dextran-based ferumoxytol and iron isomaltoside 1000, reacted with 5E7H3, whereas ferric carboxymaltose, iron sucrose, sodium ferric gluconate, and isolated isomaltoside 1000 did not. Consistent results were obtained with reverse single radial immunodiffusion assay. The results strongly support the hypothesis that, while the carbohydrate alone (isomaltoside 1000) does not form immune complexes with anti-dextran antibodies, iron isomaltoside 1000 complex reacts with anti-dextran antibodies by forming multivalent immune complexes. Moreover, non-dextran based preparations, such as iron sucrose and ferric carboxymaltose, do not react with anti-dextran antibodies. This assay allows to assess the theoretical possibility of a substance to induce antibody-mediated DIARs. Nevertheless, as this is only one possible mechanism that may cause a hypersensitivity reaction, a broader set of assays will be required to get an understanding of the mechanisms that may

    Bortezomib is a proteasome inhibitor which has demonstrated activity against recurrent or newly diagnosed multiple myeloma (MM) and mantle cell lymphoma. Peripheral neuropathy has been described with this agent, although the overall incidence and relative risk remain unclear. We performed a meta-analysis to calculate the incidence of peripheral neuropathy associated with the use of intravenous bortezomib in MM and lymphoma and to compare the relative risk compared with placebo. We searched PubMed, Embase, Cochrane databases, and meeting proceedings from the American Society of Clinical Oncology (ASCO) for relevant clinical trials. Eligible studies included prospective phase 2 and 3 clinical trials with toxicity profile on peripheral neuropathy associated with intravenous bortezomib in patients with MM and lymphoma. Statistical analyses were done to calculate summary incidences, relative risks (RRs), and 95 % confidence intervals (CIs), employing fixed- or random-effects models depending on the heterogeneity of the included studies. Altogether, 34 clinical trials were selected for the meta-analysis, yielding a total of 6492 patients. The incidence of peripheral neuropathy (all grades) was 33.9 % (95 % CI, 29.9-38.5 %) and that of high-grade events was 8.1 % (95 % CI, 6.9-9.4 %). The relative risks of bortezomib-induced peripheral neuropathy compared to placebo were increased for all-grade (RR = 4.89; 95 % CI, 2.52-9.51) and high-grade (RR = 4.53; 95 % CI, 2.04-10.07) peripheral neuropathy (for randomized controlled trials only). Our analysis was also stratified by different underlying diseases, and patients with lymphoma had an increased incidence of all-grade peripheral neuropathy than those with MM when treated with intravenous bortezomib. Treatment with intravenous bortezomib is associated with an increased risk of developing peripheral neuropathy.

    Techniques are described for multi-day intravenous (i.v.) infusions of iodinated deoxyuridine (IdUrd) into mice. Percent incorporation into DNA as a thymidine (Thd) analog is reported, as measured by radioactive tag ( 125 IdUrd) and by neutron activation analysis (NAA). Quantitative measurements of IdUrd incorporation in DNA are requisite for meaningful evaluation of the effects of radiation enhancement resulting from radiation sensitization and the stimulation of Auger cascades (photon activation)

    In term with premature rupture of the membranes (PROM) and an unripe cervix who have no contraindications for prostaglandin (PG) administration and vaginal delivery, intravenous (I.V.) infusion of titrated PGE2 is highly effective. In healthy gravidas with dito fetus this treatment appeared perinatally safe and was well tolerated by the mother. To enhance its safety margin and procedure must be conducted under toco-cardiographic control.

    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.

    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.

    Full Text Available BACKGROUND AND OBJECTIVE: Postoperative pain treatment in mastectomy remains a major challenge despite the multimodal approach. The aim of this study was to investigate the analgesic effect of intravenous lidocaine in patients undergoing mastectomy, as well as the postoperative consumption of opioids. METHODS: After approval by the Human Research Ethics Committee of the Instituto de Medicina Integral Prof. Fernando Figueira in Recife, Pernambuco, a randomized, blind, controlled trial was conducted with intravenous lidocaine at a dose of 3 mg/kg infused over 1 h in 45 women undergoing mastectomy under general anesthesia. One patient from placebo group was. RESULTS: Groups were similar in age, body mass index, type of surgery, and postoperative need for opioids. Two of 22 patients in lidocaine group and three of 22 patients in placebo group requested opioid (p = 0.50. Pain on awakening was identified in 4/22 of lidocaine group and 5/22 of placebo group (p = 0.50; in the post-anesthetic recovery room in 14/22 and 12/22 (p = 0.37 of lidocaine and placebo groups, respectively. Pain evaluation 24 h after surgery showed that 2/22 and 3/22 patients (p = 0.50 of lidocaine and placebo groups, respectively, complained of pain. CONCLUSION: Intravenous lidocaine at a dose of 3 mg/kg administered over a period of an hour during mastectomy did not promote additional analgesia compared to placebo in the first 24 h, and has not decreased opioid consumption. However, a beneficial effect of intravenous lidocaine in selected and/or other therapeutic regimens patients cannot be ruled out.

    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.
