    Spinal fusion surgery causes severe postoperative pain, hampering reconvalescense. We investigated the efficacy of patient-controlled epidural analgesia (PCEA) in a prospective, double-blind, randomized, controlled comparison with patient-controlled IV analgesia (PCIA). After lumbar anterior-posterior fusion receiving an epidural catheter intraoperatively, 72 patients were given either PCEA (ropivacaine 0.125% and sufentanil 1.0 microg/mL at 14 mL/h; bolus: 5 mL; lockout time: 15 min) and IV placebo or PCIA (morphine 2.0 mg/mL; bolus: 3 mg; lockout time: 15 min) and epidural placebo. Pain levels (visual analog scale 0-10), functional capabilities (turning in bed, standing, and walking), analgesic consumption, and side effects were evaluated until 72 h after surgery. Fourteen patients were excluded by predetermined criteria, leaving 58 patients for data analysis. Pain levels at rest and during mobilization were significantly lower in the PCEA when compared with that in the PCIA group throughout the study period (P turn in bed was achieved earlier in the PCEA group (P Patients in the PCEA group were significantly more satisfied with pain therapy (P patient satisfaction when compared with PCIA after spinal fusion surgery.

    Full Text Available Abstract Background Pain relief during labour is a topic of major interest in the Netherlands. Epidural analgesia is considered to be the most effective method of pain relief and recommended as first choice. However its uptake by pregnant women is limited compared to other western countries, partly as a result of non-availability due to logistic problems. Remifentanil, a synthetic opioid, is very suitable for patient controlled analgesia. Recent studies show that epidural analgesia is superior to remifentanil patient controlled analgesia in terms of pain intensity score; however there was no difference in satisfaction with pain relief between both treatments. Methods/design The proposed study is a multicentre randomized controlled study that assesses the cost-effectiveness of remifentanil patient controlled analgesia compared to epidural analgesia. We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia. Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief. Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity, mode of delivery and maternal and neonatal side effects. The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared. Discussion This study, considering cost

    adequate pain control after cardiac surgery is mandatory to reduce its remarkable morbidity. In this study, we aimed to compare the efficacy of patient-controlled analgesia with remifentanil or sufentanil for pain management after coronary artery bypass grafting. 249 patients who underwent coronary artery bypass were randomly assigned to receive patient-controlled analgesia with remifentanil or sufentanil during the first 24 h postoperatively. Pain intensity during patient-controlled analgesia was assessed using 4 different pain rating scales. patients given remifentanil had lower Visual Analog Scale scores at 24 h compared to those given sufentanil (p = 0.002). The Numeric Rating Scale at 24 h was also significantly lower in patients using remifentanil (p = 0.004). The Faces Pain Scale scores at 4, 18, and 24 h were significantly lower in patients using remifentanil compared to those using sufentanil (p = 0.045, 0.036, and 0.011, respectively). No significant differences between groups were seen in the pain intensity assessed by the Behavior Rating Scale at any time point during the first 24 h postoperatively. our study showed that both remifentanil and sufentanil patient-controlled analgesia can provide acceptable analgesia after coronary artery bypass. The difference between their efficacies was inconspicuous until 24 h postoperatively. Remifentanil seems to result in better pain relief at 24 h postoperatively. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Patient-controlled analgesia (PCA) is a relatively new technique in which patients are able to self-administer small doses of opioid analgesics when needed. Many different devices are available for opioid infusion, including a syringe pump, disposable plastic cylinder, and battery-operated computer-driven pump. These devices allow patients to choose an intermittent (demand) bolus, continuous infusion, or both modes of administration. Parameters, such as route, drug concentration dose, frequency, and maximum daily or hourly dose, are programmed by the physician. The patient decides whether or not to take a dose. Devices can be used to deliver the drug into a running intravenous infusion, the epidural space, or subcutaneously. Controlled trials indicate that PCA is probably superior to regular opioid administration in postoperative pain. Reported advantages include greater patient satisfaction, decreased sedation and anxiety, and reduced nursing time and hospitalization. Preliminary experience suggests that PCA is also useful and safe for cancer pain, but further research is greatly needed.

    The advantages of patient-controlled epidural analgesia (PCEA) for delivery compared with continuous epidural analgesia (CEA) have been a point of interest in research obstetric anaesthesia for more than two decades. The aim of this single blind randomized controlled study was to evaluate the incidence of motor block and ability to perform partial knee flexion in women who received CEA or PCEA. Fifty-one healthy nulliparous women were included in this study. After an initial dose and established sensory block at Th 10, parturients were randomized into two groups: group CEA (10 ml/h), and group PCEA (bolus - 5 ml, lockout interval - 15 minutes, basal rate - 0 ml) with bupivacaine 0.08% and fentanyl 2 µg/ml. The motor function of the lower limbs was evaluated by modified Bromage scale at regular hourly intervals until full cervical dilatation. The quality of analgesia was assessed using a visual analogue pain scale (VAPS) and maternal satisfaction. Mode of delivery, the total number of additional rescue boluses, foetal and neonatal outcomes were recorded. Motor block was significantly lower in the third (33.3% vs. 4.35%; p = 0.008), fourth (57.9% vs. 6.3%; p = 0.003) and fifth hour (75.0% vs. 18.2%; p = 0.001) in the PCEA group. Ambulation occurred in 18% in the CEA and 46% in the PCEA group (p = 0.036). VAPS was with borderline significance in the second (p = 0.076) and significantly lower in the fourth hour (p = 0.034). Compared with CEA, PCEA provided less motor block and better first-stage analgesia, which leads to the conclusion that patient-controlled analgesia techniques are the preferred model in obstetric anesthesia.

    The aim of the study was to check the influence of patient control epidural analgesia on labor progress and neonatal outcome. 144 parturients were included into the clinical trial. In 73 cases patient control epidural analgesia was used and in 71 cases pethidine (meperidine) solution was given intravenously. Apgar score, umbilical artery pH, pain intensity the time of the first, second and third stage of labor the rate of episiotomy and uterine postpartum abrasions and the rate of caesarean sections and vaginal operative delivery were compared. The time of the second stage of labor was significantly longer in the study group (40.99 vs 26.49 min, p- neonatal outcome was comparable in both groups. There were no differences in the time of the first and the second stage of labor in primiparas and multiparas analyzed separately. Visual Analogue Score was lower in the study group (Ch(2)-12,48, p-0.25), especially in the subgroups of primiparas and multiparas. Patient control epidural analgesia does not affect the time of the first and second stage of labor, oxytocin augmentation of labor may be the reason of that. This method is a more effective way of relieving labor pain. An increase of operative delivery is not observed after patient control epidural analgesia on condition that low doses and concentrations of analgesic drugs are used.

    Result: Morphine consumption in IV-PCA group showed lower needs than SC-PCA (9.41 mg vs 4,9mg p <0.001 24 at 24 hours postoperatively. The VAS at resting at 4th hours statistically significantly lower in IV-PCA group (1.06 ± 0.71 vs 0.81 ± 1.40, p=0.029 and at 8th hours (1.03 ± 0.59 vs 0.94 ± 0,9, p=0.048. The moving VAS at 4th hours statistically significant lower in IV-PCA group (2.31 ± 0.47 vs 1.45 ± 2.06, p=0.019 but the static or VAS at moving are not different clinically. Side effects of nausea and vomiting are more common in IV-PCA group. We conclude that SC-PCA provide analgesia more effective and decreases side effects in patients undergo sectio cesarea with spinal anesthesia.

    Purpose: This study was designed to compare the costs and effects of epidural analgesia (EDA) to those of patient-controlled intravenous analgesia (PCA) for postintervention pain relief in women having uterine artery embolization (UAE) for systematic uterine fibroids. Methods: Cost-effectiveness analysis (CEA) based on data from the literature by constructing a decision tree to model the clinical pathways for estimating the effects and costs of treatment with EDA and PCA. Literature on EDA for pain-relief after UAE was missing, and therefore, data on EDA for abdominal surgery were used. Outcome measures were compared costs to reduce one point in visual analogue score (VAS) or numeric rating scale (NRS) for pain 6 and 24 h after UAE and risk for complications. Results: Six hours after the intervention, the VAS was 3.56 when using PCA and 2.0 when using EDA. The costs for pain relief in women undergoing UAE with PCA and EDA were €191 and €355, respectively. The costs for EDA to reduce the VAS score 6 h after the intervention with one point compared with PCA were €105 and €179 after 24 h. The risk of having a complication was 2.45 times higher when using EDA. Conclusions: The results of this indirect comparison of EDA for abdominal surgery with PCA for UAE show that EDA would provide superior analgesia for post UAE pain at 6 and 24 h but with higher costs and an increased risk of complications

    Uterine artery embolism is widely used for interventional therapy of gynecology and obstetrics ailment, but immediate incidence of pain occurs in 90% to 100% after uterine artery embolism and postoperative incidence of pain takes place from 80% to 90%. Patient controlled epidural analgesia (PCEA) could be adopted to treat pain with obviously outweighed effects over the traditional drug regimen or patient intravenous analgesia during the period of interventional therapy of uterine artery embolization. PCEA possesses good effect of analgesia and less adverse reaction and furthermore could eliminate or lessen the sufferings of patient and thus improve rehabilitation quality. Adding droperidol (0.005%) into the preparation of PCEA could decrease adverse effect incidence of nausea and vomiting; so it deserves recommendation for extending application in clinical interventional therapy.

    Full Text Available Patient controlled epidural analgesia (PCEA is a well established technique for pain relief during labor. But the inclusion of continuous background infusion to PCEA is controversial. The aim of this study was to assess whether the use of continuous infusion along with PCEA was beneficial for laboring women with regards to quality of analgesia, maternal satisfaction and neonatal outcome in comparison to PCEA alone. Fifty five parturients received epidural bolus of 10ml solution containing 0.125% bupivacaine +2 ìg.ml-1 of fentanyl. For maintenance of analgesia the patients of Group PCEA self administered 8 ml bolus with lockout interval of 20 minutes of above solution on demand with no basal infusion. While the patients of Group PCEA + CI received continuous epidural infusion at the rate of 10 ml.hr-1 along with self administered boluses of 3 ml with lockout interval of 10 minutes of similar epidural solution. Patients of both groups were given rescue boluses by the anaesthetists for distressing pain. Verbal analogue pain scores, incidence of distressing pain, need of supplementary/rescue boluses, dose of bupivacaine consumed, maternal satisfaction and neonatal Apgar scores were recorded. No significant difference was observed between mean VAS pain scores during labor, maternal satisfaction, mode of delivery or neonatal Apgar scores. But more patients (n=8 required rescue boluses in PCEA group for distressing pain. The total volume consumed of bupivacaine and opioid was slightly more in PCEA + CI group. In both the techniques the highest sensory level, degree of motor block were comparable& prolongation of labor was not seen. It was concluded that both the techniques provided equivalent labor analgesia, maternal satisfaction and neonatal Apgar scores. PCEA along with continuous infusion at the rate of 10 ml/ hr resulted in lesser incidence of distressing pain and need for rescue analgesic. Although this group consumed higher dose of bupivacaine

    Multiple analgesic strategies for pain relief during labour are available. Recently remifentanil, a short-acting opioid, has recently been used as an alternative analgesic due to its unique pharmacological properties. To systematically assess the effectiveness of remifentanil intravenous patient-controlled analgesia (PCA) for labour pain, along with any potential harms to the mother and the newborn. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (9 December 2015), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP), handsearched congress abstracts (November 2015), and reference lists of retrieved studies. Randomised controlled trials (RCTs) and cluster-randomised trials comparing remifentanil (PCA) with another opioid (intravenous (IV)/intramuscular (IM)), or with another opioid (PCA), or with epidural analgesia, or with remifentanil (continuous IV), or with remifentanil (PCA, different regimen), or with inhalational analgesia, or with placebo/no treatment in all women in labour including high-risk groups with planned vaginal delivery. Two review authors independently assessed trials for inclusion, extracted data, and appraised study quality.We contacted study authors for additional information other than incomplete outcome data. We performed random-effects meta-analysis.To reduce the risk of random error in meta-analysis we performed trial sequential analysis. We included total zero event trials and used a constant continuity correction of 0.01 (ccc 0.01) for meta-analysis. We applied the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach to assess the quality of evidence. Twenty RCTs with 3569 women were included. Of those, 10 trials (2983 participants) compared remifentanil (PCA) to an epidural, four trials (216 participants) to another opioid (IV/IM), three trials (215 participants) to another opioid (PCA), two trials (135 participants) to remifentanil (continuous IV

    The aim of the study was to evaluate analgesic efficacy and tolerability of patient-controlled analgesia (PCA) with intravenous morphine. Our observational study included 50 women who underwent a Misgav-Ladach or modified Misgav-Ladach cesarean section. Automated PCA infusion device (Medima S-PCA Syringe Pump, Medima, Krakow, Poland) was used for postoperative pain control. Time of morphine administration or initiation of intravenous patient-controlled analgesia (IV PCA) with morphine was recorded, as well as post-operative pain at rest assessed by a visual analogue scale (VAS). All patients were followed up for 24 hours after discharge from the operating room, taking into account patient records, worst pain score at rest, number of IV PCA attempts, and drug consumption. Median of total morphine doses used during the postoperative period was 42.9mg (IQR 35.6-48.5), with median infusion time of 687.0 min. (IQR 531.0-757.5). Pain severity and total drug consumption improved after the first 3 hours following cesarean delivery (p PCA attempts per patient was 33 (IQR: 24-37), with median of 11 placebo attempts (IQR: 3-27). Patient-controlled analgesia with morphine is an efficient and acceptable analgesic method in women undergoing cesarean section.

    Purpose: This study was designed to compare the costs and effects of epidural analgesia (EDA) to those of patient-controlled intravenous analgesia (PCA) for postintervention pain relief in women having uterine artery embolization (UAE) for systematic uterine fibroids. Methods: Cost-effectiveness analysis (CEA) based on data from the literature by constructing a decision tree to model the clinical pathways for estimating the effects and costs of treatment with EDA and PCA. Literature on EDA for pain-relief after UAE was missing, and therefore, data on EDA for abdominal surgery were used. Outcome measures were compared costs to reduce one point in visual analogue score (VAS) or numeric rating scale (NRS) for pain 6 and 24 h after UAE and risk for complications. Results: Six hours after the intervention, the VAS was 3.56 when using PCA and 2.0 when using EDA. The costs for pain relief in women undergoing UAE with PCA and EDA were Euro-Sign 191 and Euro-Sign 355, respectively. The costs for EDA to reduce the VAS score 6 h after the intervention with one point compared with PCA were Euro-Sign 105 and Euro-Sign 179 after 24 h. The risk of having a complication was 2.45 times higher when using EDA. Conclusions: The results of this indirect comparison of EDA for abdominal surgery with PCA for UAE show that EDA would provide superior analgesia for post UAE pain at 6 and 24 h but with higher costs and an increased risk of complications.

    The aim of this study was to evaluate pain relief for patients with burns during rest and mobilization with morphine according to a standard protocol for patient-controlled analgesia (PCA). Eighteen patients with a mean (SD) burned TBSA% of 26 (20) were studied for 10 days. Using a numeric rating scale (NRS, 0 = no pain and 10 = unbearable pain), patients were asked to estimate their acceptable and worst experienced pain by specifying a number on a scale and at what point they would like addi...

    BACKGROUND: Ward-based patient-controlled epidural analgesia (PCEA) for postoperative pain control was introduced at our institution in 2006. We audited the efficacy and safety of ward-based PCEA from January 2006 to December 2008. METHOD: Data were collected from 928 patients who received PCEA in general surgical wards for postoperative analgesia using bupivacaine 0.125% with fentanyl 2 mug\\/mL. RESULTS: On the first postoperative day, the median visual analogue pain score was 2 at rest and 4 on activity. Hypotension occurred in 21 (2.2%) patients, excessive motor blockade in 16 (1.7%), high block in 5 (0.5%), nausea in 5 (0.5%) and pruritus in only 1 patient. Excessive sedation occurred in two (0.2%) patients but no intervention was required. There were no serious complications such as epidural abscess, infection or haematoma. CONCLUSION: Effective and safe postoperative analgesia can be provided with PCEA in a general surgical ward without recourse to high-dependency supervision.

    To compare the safety and efficacy of a pharmacist-managed patient-controlled analgesia (PCA) service with physician/midlevel provider-managed (standard) PCA services in postsurgical patients. This was a multicenter, retrospective cohort study performed at 3 major hospitals in the Detroit, Michigan, metropolitan area. Postsurgical patients from October 2012 to December 2013 were included. The primary outcome compared the pain area under the curve adjusted for time on PCA (AUC/T) of patients receiving pharmacist-managed PCA services vs. standard care, up to 72 hours after initiation of PCA. Secondary outcomes included initial opioid selection, programmed PCA settings, duration of PCA use, frequency of adjunct analgesia utilization, and frequency of breakthrough analgesia utilization. Safety outcomes were assessed as a composite safety endpoint and individually. Total pain AUC/T scores did not differ between the pharmacist-managed and standard-managed groups (3.25 vs. 3.25, respectively; P = 0.98). Adjunct pain medications were given with similar frequency in the 2 groups; however, significantly fewer patients required breakthrough pain medication in the pharmacist-managed group (11% vs. 36%, respectively; P patients requiring antiemetic use (46% vs. 32%; P = 0.04). A pharmacist-managed PCA service provided no difference in pain control compared to standard management. The requirement for breakthrough analgesia was decreased in the pharmacist group, while the need for antiemetic use was increased. Further research should be conducted to evaluate different PCA management strategies. © 2016 World Institute of Pain.

    Full Text Available This is a prospective randomized clinical trial to compare use of a combination of periarticular drug injection with patient- controlled analgesia (PCA to PCA alone in post-total knee arthroplasty (TKA. Thirty patients who were admitted for unilateral total knee arthroplasty were selected randomly into an Injection group or a Standard group. The periarticular injection contained Ropivacaine, Ketorolac and Adrenaline, given intra-operatively. The mean amount of opioid used was 22.87 mmol/L in the Injection group as compared to 39.78 mmol/L in the Standard group (p = 0.026. The Injection group had lower pain score at rest and during exercise (p=0.021, p=0.041, respectively, as well as better return to function (p=0.026 and shorter hospital stay (6.1 days, Injection; 7.5 days, Standard, p=0.027. Overall, the group receiving periarticular drugs injection had less pain, less narcotic usage, earlier return to function, similar experience of adverse effects and shorter hospital stays.

    Many drugs can cause neuromuscular blockade. Clindamycin-related neuromuscular blockade is commonly reported, but fatal clindamycin-induced neuromuscular blockade is rarely reported. We describe a 47-year-old woman who initially presented with endometrial carcinoma. She underwent a laparoscopic-assisted vaginal hysterectomy (LAVH) and bilateral adnexectomy under general anesthesia, secondary to antibiotic treatment with clindamycin 1.2g in 250 mL for about 30 minutes through the peripheral intravenous route during postoperative patient controlled analgesia (PCA). She became unconscious near the end of the infusion, then, despite resuscitation attempts, she died. Clindamycin appeared to have triggered delayed respiratory depression during PCA. A combination of clindamycin and fentanyl led to her respiratory depression in the fatal case.

    To investigate whether patient-controlled oral analgesia (PCOA) used by individuals receiving a total knee replacement could reduce pain, increase patient satisfaction, reduce opioid use and/or reduce opioid side effects when compared with traditional nurse (RN)-administered oral analgesia. Patients who underwent an elective total knee replacement at a quaternary care centre (Toronto Western Hospital, Toronto, Ontario) were randomly assigned to either PCOA or RN-administered short-acting oral opioids on postoperative day 2. Subjects in the RN group called the RN to receive their prescribed short-acting opioid. Subjects in the PCOA group kept a single dose of their prescribed oral opioid at their bedside and took this dose when they felt they needed it, to a maximum of one dose every 2 h. Study outcomes, collected on postoperative day 2, included pain (measured by the Brief Pain Inventory - Short Form), patient satisfaction (measured by the Pain Outcome Questionnaire Satisfaction subscale - component II), opioid use (oral morphine equivalents), opioid side effects (nausea, pruritus and/or constipation) and knee measures (maximum passive knee flexion and pain at maximum passive knee flexion, performed on the operative knee). Study outcomes were analyzed twice. First, for a subset of 73 subjects who remained in their randomly assigned group (PCOA group, n=36; RN group, n=37), randomized analyses were performed. Second, for the larger sample of 88 subjects who were categorized by their actual method of receiving oral opioids (PCOA group, n=41; RN group, n=47), as-treated analyses were performed. There were no differences in study outcomes between the PCOA and RN groups in either analysis. PCOA was not superior to RN administration on study outcomes. However, PCOA did not increase opioid use or pain. PCOA remains an important element in the patient-centred care facility.

    The aim of this study was to evaluate pain relief for patients with burns during rest and mobilization with morphine according to a standard protocol for patient-controlled analgesia (PCA). Eighteen patients with a mean (SD) burned TBSA% of 26 (20) were studied for 10 days. Using a numeric rating scale (NRS, 0 = no pain and 10 = unbearable pain), patients were asked to estimate their acceptable and worst experienced pain by specifying a number on a scale and at what point they would like additional analgesics. Patients were allowed free access to morphine with a PCA pump device. Bolus doses were set according to age, (100 - age)/24 = bolus dose (mg), and 6 minutes lockout time. Degrees of pain, morphine requirements, doses delivered and demanded, oral intake of food, and antiemetics given were used as endpoints. Acceptable pain (mean [SD]) was estimated to be 3.8 (1.3) on the NRS, and additional treatment was considered necessary at scores of 4.3 (1.6) or more. NRS at rest was 2.7 (2.2) and during mobilization 4.7 (2.6). Required mean morphine per day was 81 (15) mg, and the number of doses requested increased during the first 6 days after the burn. The authors found no correlation between dose of morphine required and any other variables. Background pain can be controlled adequately with a standard PCA protocol. During mobilization, the pain experienced was too intense, despite having the already high doses of morphine increased. The present protocol must be refined further to provide analgesia adequate to cover mobilization as well.

    Full Text Available Introduction: Postoperative pain control plays a pivotal role in reducing postoperative complications, hospitality time, and increasing satisfaction. This study aimed to evaluate the effect of paracetamol on the pain and complications caused by gastrectomy. Materials and Methods: This randomized prospective study was conducted on 60 patients (two same group who were candidate for gastrectomy in Imam Reza Hospital of Mashhad, Iran during August-September 2015. The first group received Patient-Controlled Analgesia (PCA with morphine only, and in the second group, paracetamol (1 gram infused with morphine every six hours. Level of pain, morphine intake, and side effects were evaluated in both groups. Results:No significant difference was observed in the four-scale score of pain in the patients (morphine group: 0.64±0.1, morphine-paracetamol group: 0.6±0.1 (P=0.72. During the first 24 hours after the surgery, the morphine group had lower consciousness level (2.3±0.2 compared to the morphine-paracetamol group (1.7±0.3 (P=0.001. Moreover, infusion of paracetamol with morphine to control the pain after gastrectomy reduced the need for morphine analgesia. Morphine intake was 21.4±7.7 in morphine group, while it was 14.3±5.8 in the morphine-paracetamol group within the first 24 hours after the surgery (P=0.001. However, this level had no significant effect on postoperative complications such as itching, nausea, and arterial oxygen saturation. Conclusion: According to the results of this study, intravenous paracetamol (one gram administered every six hours with PCA using morphine could decrease morphine intake leading to better consciousness level during the first 24 hours after gastrectomy without further complications.

    Subanesthetic doses of ketamine as an adjuvant to tramadol in patient-controlled analgesia (PCA) for postoperative pain have been shown to improve the quality of analgesia. However, there are no such commercially available drug mixtures, and the stability of the combination has rarely been assessed. Admixtures were assessed for periods of up to 14 days at 4°C and 25°C. Three different mixtures of tramadol and ketamine (tramadol 5.0 mg/mL + ketamine 0.5 mg/mL, tramadol 5.0 mg/mL + ketamine 1.0 mg/mL, and tramadol 5.0 mg/mL + ketamine 2.0 mg/mL) were prepared in polyolefin bags by combining these 2 drugs with 0.9% sodium chloride (normal saline [NS]). The chemical stability of the admixtures was evaluated by a validated high-performance liquid chromatography (HPLC) method and by measurement of pH values. Solution appearance and color were assessed by observing the samples against black and white backgrounds. Solutions were considered stable if they maintained 90% of the initial concentration of each drug. The percentages of initial concentration of tramadol and ketamine in the various solutions remained above 98% when stored at 4°C or 25°C over the testing period. No changes in color or turbidity were observed in any of the prepared solutions. Throughout this period, pH values remained stable. The results indicate that the drug mixtures of tramadol with ketamine in NS for PCA delivery systems were stable for 14 days when stored in polyolefin bags at 4°C or 25°C.

    Background Ropivacaine and levobupivacaine have been introduced into obstetric analgesic practice with the proposed advantages of causing less motor block and toxicity compared with bupivacaine. However, it is still controversial whether both anesthetics are associated with any clinical benefit relative to bupivacaine for labor analgesia. This study aimed to compare the analgesic efficacy, motor block and side effects of bupivacaine, ropivacaine and levobupivacaine at lower concentrations for patient-controlled epidural labor analgesia. Methods Four hundred and fifty nulliparous parturients were enrolled in this randomized clinical trial. A concentration of 0.05%, 0.075%, 0.1%, 0.125% or 0.15% of either bupivacaine (Group B), ropivacaine (Group R) or levobupivacaine (Group L) with sufentanil 0.5 μg/ml was epidurally administered by patient-controlled analgesia mode. Effective analgesia was defined as a visual analogue scale score was ≤30 mm. The relative median potency for each local anesthetic was calculated using a probit regression model. Parturients demographics, sensory and motor blockade, obstetric data, maternal side effects, hourly volumes of local anesthetic used, and others were also noted. Results There were no significant differences among groups in the numbers of effective analgesia, pain scores, hourly local anesthetic amount used, sensory and motor blockade, labor duration and mode of delivery, side effects and maternal satisfaction (P >0.05). The relative median potency was bupivacaine/ropivacaine: 0.828 (0.602-1.091), bupivacaine/levobupivacaine: 0.845 (0.617-1.12), ropivacaine/levobupivacaine: 1.021 (0.774-1.354), respectively. However, a significantly less number of effective analgesia and higher hourly local anesthetic use were observed in the concentration of 0.05% than those of ≥0.1% within each group (P<0.05). Conclusions Using patient-controlled epidural analgesia, lower concentrations of bupivacaine, ropivacaine and levobupivacaine

    The purpose was to add to the body of knowledge regarding the impact of interruption on acute care nurses' cognitive workload, total task completion times, nurse frustration, and medication administration error while programming a patient-controlled analgesia (PCA) pump. Data support that the severity of medication administration error increases with the number of interruptions, which is especially critical during the administration of high-risk medications. Bar code technology, interruption-free zones, and medication safety vests have been shown to decrease administration-related errors. However, there are few published data regarding the impact of number of interruptions on nurses' clinical performance during PCA programming. Nine acute care nurses completed three PCA pump programming tasks in a simulation laboratory. Programming tasks were completed under three conditions where the number of interruptions varied between two, four, and six. Outcome measures included cognitive workload (six NASA Task Load Index [NASA-TLX] subscales), total task completion time (seconds), nurse frustration (NASA-TLX Subscale 6), and PCA medication administration error (incorrect final programming). Increases in the number of interruptions were associated with significant increases in total task completion time ( p = .003). We also found increases in nurses' cognitive workload, nurse frustration, and PCA pump programming errors, but these increases were not statistically significant. Complex technology use permeates the acute care nursing practice environment. These results add new knowledge on nurses' clinical performance during PCA pump programming and high-risk medication administration.

    Patient-controlled oral analgesia (PCOA) allows patients to self-administer oral opioids for pain management. Advantages of PCOA include improved pain control with lower doses of opioids, decreased length of stay, increased patient satisfaction, and better functional outcomes than conventional nurse-administered oral analgesia. Sucessful PCOA programs are well described in the literature. However, nurses have concerns about allowing patients to self-administer opioids. The purpose of this study was to identify nurses' knowledge and beliefs regarding PCOA. Nurses who work at the Holland Orthopaedic and Arthritic Centre were asked to complete a survey exploring their beliefs regarding PCOA. The nurses were asked to complete the same survey twice: before an education program in February 2010, and 3 months after implementation of PCOA in June 2010. In February 2010, 74 nurses and in June 2010, 32 nurses participated in the survey. Some nurses (18%) had previous experience with PCOA. At both the pre-education and the postimplementation times, nurses thought that the PCOA program reduced wait times for analgesics and improved patient satisfaction with pain management. Before program implementation, negative beliefs included that patients on the PCOA program would lose their analgesics, would give their analgesics to visitors or other patients, and were at risk for having their analgesics stolen and that the nurse was liable if the patient's analgesics were lost or stolen. After program implementation, no nurse believed that patients would lose their analgesics or give their analgesics to visitors or other patients or that they were liable for lost or stolen analgesics. However, nurses continued to think that patients were at risk for having their analgesics stolen. We found that nurses were concerned that analgesics could be lost, misused, or stolen and that they would be liable for lost analgesics. These findings were consistent with literature discussing patients

    This trial aimed to compare the maternal and neonatal effects of remifentanil given by patient-controlled analgesia (PCA) or continuous infusion for labour analgesia. Patient controlled analgesia was administered using increasing stepwise boluses from 0.1 to 0.4 μg.kg(-1) (0.1 μg.kg(-1) increment, 2 min lockout, n = 30). Continuous infusion used rates from 0.05 to 0.2 μg.kg(-1) .min(-1) (0.05 μg.kg(-1) .min(-1) increment, n = 30). Dose increments were given on request. Women reported lowest pain scores (median (IQR [range]) of 3 (2-4 [2-5]) for PCA and 4 (3-5.25 [3-7]) for continuous infusion (p = 0.004) at 60 min after the beginning of analgesia. The mean (SD) remifentanil umbilical vein/maternal artery ratio in the PCA and infusion groups were 0.74 (0.45) vs 0.70 (0.52), respectively (p = 0.776). The mean (SD) umbilical artery/umbilical vein ratios were 0.31 (0.12) vs 0.26 (0.07), respectively (p = 0.088). Maternal and neonatal adverse reactions of remifentanil were similar between the two groups. The total remifentanil consumption (median (IQR [range]) during PCA administration was lower than continuous infusion, 1.34 (1.22-1.48 [0.89-1.69]) mg vs 1.49 (1.35-1.61 [1.12-1.70] mg; p = 0.011). The results suggest that remifentanil PCA provides better pain relief and similar placental transfer compared with continuous infusion.

    The use of intravenous patient-controlled analgesia (IV-PCA) has been increasing because it has advantages such as improved pain relief, greater patient satisfaction, and fewer postoperative complications. However, current research has not considered the patients' thoughts about IV-PCA's cost-effectiveness. The purpose of this study was to investigate the willingness to pay (WTP) for IV-PCA and the relationship between patients' characteristics and WTP in Korea. We enrolled 400 adult patients who were scheduled for elective surgery. The patient was requested to indicate a series of predefined amounts of money (Korean won; 30,000/50,000/100,000/150,000/200,000/300,000/500,000). We also recorded patient characteristics, such as age, sex, type of surgery, IV-PCA history, education level, the person responsible for medical expenses, type of insurance, net annual income, and residential area. Three days after surgery, we asked about the degree of satisfaction and the WTP for IV-PCA. For IV-PCA, the median WTP was 100,000 won (25-75%; 50,000-200,000 won: US$1 = W1078.04; July 19, 2011) before surgery. All patients' characteristics were not related to preoperative WTP for IV-PCA, whereas the increase in WTP after surgery showed a tendency correlated to higher IV-PCA satisfaction. The median WTP was 100,000 won. The satisfaction of IV-PCA increased patients' WTP after surgery, but the WTP may be independent of patient characteristics in Korea.

    A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'is the addition of ketamine to morphine patient-controlled analgesia (PCA) following thoracic surgery superior to morphine alone'. Altogether 201 papers were found using the reported search, of which nine represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. This consisted of one systematic review of PCA morphine with ketamine (PCA-MK) trials, one meta-analysis of PCA-MK trials, four randomized controlled trials of PCA-MK, one meta-analysis of trials using a variety of peri-operative ketamine regimes and two cohort studies of PCA-MK. Main outcomes measured included pain score rated on visual analogue scale, morphine consumption and incidence of psychotomimetic side effects/hallucination. Two papers reported the measurements of respiratory function. This evidence shows that adding ketamine to morphine PCA is safe, with a reported incidence of hallucination requiring intervention of 2.9%, and a meta-analysis finding an incidence of all central nervous system side effects of 18% compared with 15% with morphine alone, P = 0.31, RR 1.27 with 95% CI (0.8-2.01). All randomized controlled trials of its use following thoracic surgery found no hallucination or psychological side effect. All five studies in thoracic surgery (n = 243) found reduced morphine requirements with PCA-MK. Pain scores were significantly lower in PCA-MK patients in thoracic surgery papers, with one paper additionally reporting increased patient satisfaction. However, no significant improvement was found in a meta-analysis of five papers studying PCA-MK in a variety of surgical settings. Both papers reporting respiratory outcomes found improved oxygen saturations and PaCO(2) levels in PCA-MK patients following thoracic surgery

    Full Text Available Abstract Background Appropriate postoperative pain management contributes to earlier mobilization, shorter hospitalization, and reduced cost. The under treatment of pain may impede short-term recovery and have a detrimental long-term effect on health. This study focuses on Patient Controlled Analgesia (PCA, which is a delivery system for pain medication. This study proposes and demonstrates how to use machine learning and data mining techniques to predict analgesic requirements and PCA readjustment. Methods The sample in this study included 1099 patients. Every patient was described by 280 attributes, including the class attribute. In addition to commonly studied demographic and physiological factors, this study emphasizes attributes related to PCA. We used decision tree-based learning algorithms to predict analgesic consumption and PCA control readjustment based on the first few hours of PCA medications. We also developed a nearest neighbor-based data cleaning method to alleviate the class-imbalance problem in PCA setting readjustment prediction. Results The prediction accuracies of total analgesic consumption (continuous dose and PCA dose and PCA analgesic requirement (PCA dose only by an ensemble of decision trees were 80.9% and 73.1%, respectively. Decision tree-based learning outperformed Artificial Neural Network, Support Vector Machine, Random Forest, Rotation Forest, and Naïve Bayesian classifiers in analgesic consumption prediction. The proposed data cleaning method improved the performance of every learning method in this study of PCA setting readjustment prediction. Comparative analysis identified the informative attributes from the data mining models and compared them with the correlates of analgesic requirement reported in previous works. Conclusion This study presents a real-world application of data mining to anesthesiology. Unlike previous research, this study considers a wider variety of predictive factors, including PCA

    Full Text Available Pain intensity may be high in the postoperative period after spinal vertebral surgery. The aim of the study was to compare the effectiveness and cost of patient controlled analgesia (PCA with tramadol versus low dose tramadol-paracetamol on postoperative pain. A total of 60 patients were randomly divided into two groups. One group received 1.5 mg/kg tramadol (Group T while the other group received 0.75 mg/kg tramadol plus 1 g of paracetamol (Group P intravenously via a PCA device immediately after surgery and the patients were transferred to a recovery room, Tramadol was continuously infused at a rate of 0.5 mL/h in both groups, at a dose of 10 mg/mL in Group T and 5 mg/mL in Group P. The bolus and infusion programs were adjusted to administer a 1 mL bolus dose of tramadol with a lock time of 10 minutes. In Group P, 1 g of paracetamol was injected intravenously every 6 hours. The four-point nausea scale, numeric rating scale for pain assessment, Ramsey sedation scale, blood pressure, heart rate, respiration rate, peripheral oxygen saturation values and side effects were recorded at 0, 15 and 30 minutes, and at 1, 2, 4, 6, 12, 18 and 24 hours. The time to reach an Aldrete score of 9 was also recorded. A cost analysis for both groups was performed. In Group P, the numeric rating scale scores were significantly lower than that in Group T at 0 and 15 minutes. The number of side effects, additional analgesic requirement and the total dose of tramadol were lower in Group P than in Group T. However, the total cost of postoperative analgesics was significantly higher in Group P than in Group T (p < 0.001. We conclude that PCA using tramadol-paracetamol could be used safely for postoperative pain relief after spinal vertebral surgery, although at a higher cost than with tramadol alone.

    In experimental trials, ketamine has been shown to reduce hyperalgesia, prevent opioid tolerance, and lower morphine consumption. Clinical trials have found contradictory results. We performed a review of randomized, double-blinded clinical trials of ketamine added to opioid in i.v. patient......-controlled analgesia (PCA) for postoperative pain in order to clarify this controversy. Our primary aim was to compare the effectiveness and safety of postoperative administered ketamine in addition to opioid for i.v. PCA compared with i.v. PCA with opioid alone. Studies were identified from the Cochrane Library 2003...... of 4.5. Pain was assessed using visual analogue scales or verbal rating scales. Six studies showed significant improved postoperative analgesia with the addition of ketamine to opioids. Five studies showed no significant clinical improvement. For thoracic surgery, the addition of ketamine to opioid...

    Full Text Available >Background and Aims: Lumbar epidural analgesia is considered the modality of choice for labour analgesia. Despite its super analgesia and improved safety profile, it has been associated with maternal adverse effects like higher incidence of instrumental assisted vaginal delivery (AVD and motor block leading to decreased ambulation. This study was designed to evaluate the efficacy of low concentrations of local anaesthetics (0.1% ropivacaine and 0.1% levobupivacaine with 2 μg/ml fentanyl as a patient controlled epidural analgesia (PCEA technique on the incidence of instrumental AVD along with evaluation of obstetric, maternal, and foetal outcomes.Materials and Methods: In this prospective study, 60 labouring parturients were randomly allocated into two equal groups to receive either 0.1% ropivacaine with 2 μg/ml fentanyl or 0.1% levobupivacaine with 2 μg/ml fentanyl as epidural solutions via PCEA pump infusions (4 ml/h after 15 ml loading dose of the respective solutions. The incidence of instrumental AVD was noted as the primary outcome along with demographic data, maternal and foetal vital parameters, maternal VAS scores, degree of motor blockade and total epidural drug consumption.Results: The incidence of instrumental AVD was found to be 43.3% in the levobupivacaine group and 30% in the ropivacaine group. This difference was not statistically significant. Both the groups were comparable in terms of demographic data, maternal VAS scores, total epidural drug consumption and foetal APGAR scores.Conclusion: The use of newer local anaesthetics (levobupivacaine and ropivacaine in low concentrations with opioids (fentanyl as a PCEA technique may offer high maternal satisfaction in terms of quality of pain relief with fewer adverse events like instrumental AVD and adverse foetal outcomes.

    Pain treatment in laparoscopic cholecystectomy, which is performed in increasing numbers as an ambulatory procedure, is an important issue.Although laparoscopic cholecystectomy is regarded as an ambulatory procedure, patients are often hospitalized due to pain and this increases opioid consumption and side effects caused by opioids. This study aims at evaluating the efficacy of adding dexketoprofen trometamol to tramadol with patient controlled analgesia (PCA) in postlaparoscopic cholecystectomy pain treatment. 40 patients in ASA I-II risk groups aged between 18-65 years were enrolled in the study and were randomized using closed envelope method. In Group TD 600 mg tramadol and 100 mg dexketoprofen trometamol, in Group T 600 mg tramadol was added to 100 ml 0.9% normal saline for PCA. 8 mg lornoxicam iv was given if VAS >40 in the postoperative period. There was no statistically significant difference in terms of adverse effects (hypotension, bradycardia, sedation) but in Group T 4 patients complained of nausea and 3 complained of vomiting. Opioid consumption was lower and patient satisfaction was higher in group TD. This study has shown that adding dexketoprofen trometamol to tramadol in patient controlled analgesia following laparoscopic cholecystectomy lowers VAS scores, increases patient satisfaction and decreases opioid consumption.

    Prolonged nerve conduction blockade has been proposed to result from the summed effects of charged and neutral local anaesthetics. Thirty-seven patients were randomly allocated to receive intravenous patient-controlled analgesia alone or combined with intercostal blockade (T7-T11) with a mixture of 0.45% bupivacaine and 0.6% phenol for post-cholecystectomy analgesia. Adequacy of pain relief was measured by patient scores on a 10-cm visual analogue scale and by dose-demand ratio, amounts of loading dose and total consumption of morphine and also the duration of patient-controlled analgesia in each group. No differences were found between groups in post-operative scores, dose-demand ratios and loading doses of morphine. However, in the combined treatment group, a significantly lower total consumption of morphine (P < 0.05), associated with a shorter duration of patient-controlled analgesia (P < 0.02) and a decreased mean number of unsuccessful demands (P < 0.001) were recorded. Intercostal blockade with bupivacaine-phenol supplements intravenous patient-controlled analgesia for post-cholecystectomy pain relief.

One hundred six patients scheduled for office hysteroscopy and polypectomy were divided into the following 3 groups: the control group, the nitrous oxide group, and the paracervical infiltration group. Patients were assigned sequentially (Canadian Task Force classification II-1). The study took place in a hysteroscopy outpatient clinic under the supervision of a gynecologist and 2 nurses trained to cooperate in the trial. One hundred six women from Area III of Madrid Community, Spain, who had been diagnosed with endometrial polyps at a gynecology office and were scheduled for office hysteroscopy and polypectomy agreed to participate in the study. Patients in group 1 (control group) received no treatment. Group 2 received inhaled nitrous oxide and group 3 paracervical infiltration with 1% lidocaine. Pain was assessed using the visual analog scale (0-10). Pain perceived by patients was lower in the nitrous Oxide group (mean: 3.55 ± 0.60, median: 3) versus the control group (mean: 5.49 ± 1.88, median: 6, p nitrous oxide group, and good for the paracervical infiltration group (p nitrous oxide group, whereas in the paracervical infiltration group, there were complications in more than 50% of the patients. No severe complications occurred. Nitrous oxide is a safe and effective analgesic technique for polipectomy office hysteroscopy compared with the paracervical infiltration and control groups.

The study was designed to compare propofol and midazolam with regard to their suitability for the patient-controlled sedation (PCS technique during epidural analgesia. Patients were divided into three equal groups and premedicated with 0.2mg.kg -1 oral midazolam. Group I (G1 served as control. Using PCS technique, the pump was programmed to deliver on demand a bolus dose of 0.5 mg.kg- 1 of propofol in Group II (G2 or 0.1mg.kg -1 midazolam in Group III(G3. Patient′s sedation status was assessed by sedation score, comfort scale and by psychometric testing. The total delivered dose of each tested drug was calculated. Serum concentrations of propfol and midazolam, plasma cortisol and free fatty acids were measured. Propofol and midazolam PCS technique produced excellent and easily controllable sedation. The dose needed to produce steady state sedation was 2.8±1.42 and 0.11±0.6 mg.kg -1 .h- 1 for propofol and midazolam respectively. Propofol was more suitable than midazolam for PCS because of its rapid onset, favorable recovery profile and low side effects. PCS proved to be a stress-free and acceptable technique.

    BACKGROUND: Patient-controlled analgesia (PCA) is a common and effective means of managing post-operative pain. We sought to identify factors that may lead to critical incidents (CIs) in patient safety when using PCA in our institution. METHODS: An observational study of prospectively collected data of patients who received PCA from 2002 to 2006 was performed. All CIs were documented and analysed by staff members of the acute pain service (APS). Cause analysis of CIs was undertaken to determine if measures can be instituted to prevent recurrence of similar events. RESULTS: Over eight thousand patients (8,240) received PCA. Twenty-seven CIs were identified. Eighteen were due to programming errors. Other CIs included co-administration of opioids and oversedation. CONCLUSION: In our institution, the largest contributory factor to CIs with PCAs was programming error. Strategies to minimize this problem include better education and surveillance.

    Postoperative pain is caused by surgical injury and trauma; is stressful to patients; and includes a series of physiologic, psychological, and behavioral reactions. Effective postoperative analgesia helps improve postoperative pain, perioperative safety, and hospital discharge rates. This study aimed to observe the influence of postoperative intravenous sufentanil patient-controlled analgesia combined with music therapy versus sufentanil alone on hemodynamics and analgesia in patients with lung cancer. This was a randomized parallel study performed in 60 patients in American Society of Anesthesiologists class I or II undergoing lung cancer resection at the Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University. Patients were randomly assigned to a music therapy (MT) group and a control (C) group. The MT group underwent preoperative and postoperative music intervention while the C group did not. Both groups received intravenous patient-controlled sufentanil analgesia. The primary outcome was the visual analogue scale (VAS) score at 24 hours after surgery. The secondary outcomes included hemodynamic changes (systolic blood pressure, diastolic blood pressure, heart rate), changes on the Self-Rating Anxiety Scale (SAS), total consumption of sufentanil, number of uses, sedation, and adverse effects. The postoperative sufentanil dose and analgesia frequency were recorded. Compared with the C group, the MT group had significantly lower VAS score, systolic and diastolic blood pressure, heart rate, and SAS score within 24 hours after surgery (p music therapy and sufentanil improves intravenous patient-controlled analgesia effects compared with sufentanil alone after lung cancer surgery. Lower doses of sufentanil could be administered to more effectively improve patients' cardiovascular parameters.

    A method of determining placental intervillous blood flow (IBF) using an inhaled 133 Xe technique is described. The method was used to investigate the effect on IBF of epidural analgesia with an initial dose of 37.5 mg bupivacaine. There was no statistically significant reduction in IBF following the initial dose of bupivacaine in spite of a small but statistically significant reduction in mean blood pressure. There was no significant correlation between the change in mean blood pressure and the percentage change in IBF following epidural block although the single largest percentage reduction in IBF was associated with the largest fall in mean blood pressure.

    Chronic pain poses a major concern to modern medicine and is frequently undertreated, causing suffering and disability. Patient-controlled analgesia, although successful, does have limitations. Transdermal delivery is the pivot to which analgesic research in drug delivery has centralized, especially with the confines of needle phobias and associated pain related to traditional injections, and the existing limitations associated with oral drug delivery. Highlighted within is the possibility of further developing transdermal drug delivery for chronic pain treatment using iontophoresis-based microneedle array patches. A concerted effort was made to review critically all available therapies designed for the treatment of chronic pain. The drug delivery systems developed for this purpose and nondrug routes are elaborated on, in a systematic manner. Recent developments and future goals in transdermal delivery as a means to overcome the individual limitations of the aforementioned delivery routes are represented as well. The approval of patch-like devices that contain both the microelectronic-processing mechanism and the active medicament in a small portable device is still awaited by the pharmaceutical industry. This anticipated platform may provide transdermal electro-activated and electro-modulated drug delivery systems a feasible attempt in chronic pain treatment. Iontophoresis has been proven an effective mode used to administer ionized drugs in physiotherapeutic, diagnostic, and dermatological applications and may be an encouraging probability for the development of devices and aids in the treatment of chronic pain. © 2013 Wiley Periodicals, Inc. and the American Pharmacists Association.

    This study aimed to (1) identify patient-controlled analgesia (PCA) attributes that negatively impact patient satisfaction and ability to control pain while using PCA and (2) obtain data on patient perceptions of new PCA design features. We conducted a prospective survey study of postoperative pain control among patients using a PCA device. The survey was designed to evaluate patient satisfaction with pain control, understanding of PCA, difficulties using PCA, lockout-period management, and evaluation of new PCA design features. A total of 350 eligible patients completed the survey (91%). Patients who had difficulties using PCA were less satisfied (P PCA. Forty-nine percent of patients reported not knowing if they would receive medicine when they pushed the PCA button, and of these, 22% believed that this uncertainty made their pain worse. The majority of patients preferred the proposed PCA design features for easier use, including a light on the button, making it easier to find (57%), and a PCA button that vibrates (55%) or lights up (70%), alerting the patient that the PCA pump is able to deliver more medicine. A majority of patients, irrespective of their satisfaction with PCA, preferred a new PCA design. Certain attributes of current PCA technology may negatively impact patient experience, and modifications could potentially address these concerns and improve patient outcomes.

    Objective: To study the effectiveness and safety of epidural patient-controlled analgesia (PCEA) for post-operative pain relief and adverse reactions after uterine arterial embolization (UAE). Methods: 100 patients (ASA I-II grade) undergoing transcatheter UAE of uterine myomata were randomly divided into five groups. All patients except group V used PCEA; including group I ( n=20) for epidural infusion with 0.2% ropivacaine plus 0.004% morphine, group II (n=20) with epidural infusion of 0.2% ropivacaine and 0.004% morphine plus 0.005% droperidol, group III (n=20) with epidural infusion of 0.2% ropivacaine and 0.004% morphine plus 0.01% droperidol, group IV (n=20) of epidural infusion of 0.2% ropivacaine plus 0.01% morphine, group V (n=20) served as the control with either traditional oral drugs of micronized nimesulide, or intramuscular injection (plus analgesic of rotundin or pethidine hydrochloride), or both. Results The quality of pain relief in the group I, group II, group III and group IV was obviously superior to that of group V. The PCEA application group recovered faster than that of group V after the procedure (P<0.01). Conclusions: During or after UEA, PCEA could effectively relieve pain by providing less side effects, faster recovery and high safety to the patient. The best analgetic methods of PCEA are coincident with the use of 0.2% ropivacaine plus 0.01% morphine. (authors)

At the same time, with the aging of the population, the postoperative recovery period became the focus of major concern for the healthcare team. For such, new analgesic techniques were developed, among them, Patient Controlled Analgesia (PCA. In Brazil, the Acute Pain Service (SEDA of the Anesthesiology Department, Botucatu Medical School - UNESP, has been using PCA for many years. Aiming at verifying the quality of the service provided, this research has evaluated the efficacy and safety of the technique, in addition to identifying and characterizing patients submitted to PCA. METHODS: Participated in this retrospective study 679 patients treated by SEDA with the PCA method only, during a 3-year period. Patients were randomly included in the study with no restrictions concerning age, gender and type of surgery, considering only the possibility of PCA. The following parameters were evaluated: gender, age, type of surgery, pain score, treatment duration, analgesic drugs used, administration route, side effects and complications. RESULTS: The PCA technique was used in 3.96% of patients submitted to surgical procedures and in 1.64% of all hospitalized patients. Thoracic surgeries were the most frequent procedures and accounted for 25% of patients. Morphine was the most commonly used analgesics (54.2% and the epidural route was the most frequent route of

    Remifentanil has a suitable pharmacological profile for labour analgesia. In this prospective, observational study, intravenous patient-controlled analgesia with remifentanil, using stepwise bolus doses without background infusion, was examined during the first and second stages of labour. Outcomes were pain reduction, maternal satisfaction, maternal and neonatal side effects and remifentanil metabolism in the neonate. Parturients with normal term singleton pregnancies were recruited. The initial remifentanil bolus dose was 0.15 μg/kg, increasing in steps of 0.15 μg/kg, with a 2-min lock-out. Pain scores using a 100 mm visual analogue scale, systolic and diastolic blood pressures, respiratory rate and maternal sedation were recorded every 15 min. Maternal oxygen saturation and heart rate were monitored continuously. Neonatal data included Apgar scores, clinical examination, naloxone use, resuscitation, umbilical cord blood gases and remifentanil concentrations. Forty-one parturients were enrolled. Pain scores were significantly reduced in the first 3 h of patient-controlled analgesia use compared to baseline, and at the end of the first and second stages of labour (Panalgesia. The mean highest dose of remifentanil was 0.7 μg/kg [range 0.3-1.05]. Ninety-three percent of patients were satisfied with their analgesia. The lowest oxygen saturation was 91% and the lowest respiratory rate was 9 breaths/min. Eleven parturients (27%) received supplemental oxygen due to oxygen saturations neonatal data reassuring. Remifentanil intravenous patient-controlled analgesia provides adequate pain relief and high maternal satisfaction during the first and second stages of labour. Maternal sedation and respiratory depression may occur, but no serious neonatal side effects were recorded. Careful monitoring is mandatory. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Jae Chul Koh, Young Song, So Yeon Kim, Sooyeun Park, Seo Hee Ko, Dong Woo Han Department of Anesthesiology and Pain Medicine, Anesthesia and Pain Research Institute, Yonsei University College of Medicine, Seoul, South Korea Abstract: In this retrospective study, data of 2,435 patients who received fentanyl and ropivacaine-based patient-controlled epidural analgesia (PCEA for pain relief after elective surgery under general or spinal anesthesia were reviewed. Differences in postoperative pain, incidence of patient-controlled analgesia (PCA-related adverse effects, and risk factors for the need for rescue analgesics for 48 hours postsurgery in young (age 20–39 years and elderly (age ≥70 years patients were evaluated. Although there were no significant differences in postoperative pain intensity between the two groups until 6 hours postsurgery, younger patients experienced greater postoperative pain intensity compared with older patients 6–48 hours postsurgery. While younger patients exhibited greater incidence of numbness, motor weakness, and discontinuation of PCA postsurgery, elderly patients exhibited greater incidence of hypotension, nausea/vomiting, rescue analgesia, and antiemetic administration. Upon multivariate analysis, low fentanyl dosage and history of smoking were found to be associated with an increased need for rescue analgesia among younger patients, while physical status classification III/IV and thoracic surgery were associated with a decreased need for rescue analgesia among the elderly. Discontinuation of PCA was more frequent among younger patients than the elderly (18.5% vs 13.5%, P=0.001. Reasons for discontinuation of PCA among young and elderly patients, respectively, were nausea and vomiting (6.8% vs 26.6%, numbness or motor weakness (67.8% vs 11.5%, urinary retention (7.4% vs 8.7%, dizziness (2.2% vs 5.2%, and hypotension (3.1% vs 20.3%.

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

    The purpose of this study was to assess the presence and severity of pain levels during 24 h after uterine fibroid embolization (UFE) for symptomatic leiomyomata and compare the effectiveness and adverse effects of morphine patient-controlled analgesia (PCA) versus fentanyl PCA. We carried out a prospective, nonrandomized study of 200 consecutive women who received UFE and morphine or fentanyl PCA after UFE. Pain perception levels were obtained on a 0-10 scale for the 24-h period after UFE. Linear regression methods were used to determine pain trends and differences in pain trends between two groups and the association between pain scores and patient covariates. One hundred eighty-five patients (92.5%) reported greater-than-baseline pain after UFE, and 198 patients (99%) required IV opioid PCA. One hundred thirty-six patients (68.0%) developed nausea during the 24-h period. Seventy-two patients (36%) received morphine PCA and 128 (64%) received fentanyl PCA, without demographic differences. The mean dose of morphine used was 33.8 ± 26.7 mg, while the mean dose of fentanyl was 698.7 ± 537.4 μg. Using this regimen, patients who received morphine PCA had significantly lower pain levels than those who received fentanyl PCA (p < 0.0001). We conclude that patients develop pain requiring IV opioid PCA within 24 h after UFE. Morphine PCA is more effective in reducing post-uterine artery embolization pain than fentanyl PCA. Nausea is a significant adverse effect from opioid PCA.

    Data collection systems are very important for the practice of patient-controlled analgesia (PCA). This study aimed to evaluate 3 PCA data collection systems and selected the most favorable system with the aid of multiattribute utility (MAU) theory. We developed a questionnaire with 10 items to evaluate the PCA data collection system and 1 item for overall satisfaction based on MAU theory. Three systems were compared in the questionnaire, including a paper record, optic card reader and personal digital assistant (PDA). A pilot study demonstrated a good internal and test-retest reliability of the questionnaire. A weighted utility score combining the relative importance of individual items assigned by each participant and their responses to each question was calculated for each system. Sensitivity analyses with distinct weighting protocols were conducted to evaluate the stability of the final results. Thirty potential users of a PCA data collection system were recruited in the study. The item "easy to use" had the highest median rank and received the heaviest mean weight among all items. MAU analysis showed that the PDA system had a higher utility score than that in the other 2 systems. Sensitivity analyses revealed that both inverse and reciprocal weighting processes favored the PDA system. High correlations between overall satisfaction and MAU scores from miscellaneous weighting protocols suggested a good predictive validity of our MAU-based questionnaire. The PDA system was selected as the most favorable PCA data collection system by the MAU analysis. The item "easy to use" was the most important attribute of the PCA data collection system. MAU theory can evaluate alternatives by taking into account individual preferences of stakeholders and aid in better decision-making. Copyright © 2010 Elsevier. Published by Elsevier B.V.

  13. Labour analgesia: Recent advances

    Advances in the field of labour analgesia have tread a long journey from the days of ether and chloroform in 1847 to the present day practice of comprehensive programme of labour pain management using evidence-based medicine. Newer advances include introduction of newer techniques like combined spinal epidurals, low-dose epidurals facilitating ambulation, pharmacological advances like introduction of remifentanil for patient-controlled intravenous analgesia, introduction of newer local anaesthetics and adjuvants like ropivacaine, levobupivacaine, sufentanil, clonidine and neostigmine, use of inhalational agents like sevoflourane for patient-controlled inhalational analgesia using special vaporizers, all have revolutionized the practice of pain management in labouring parturients. Technological advances like use of ultrasound to localize epidural space in difficult cases minimizes failed epidurals and introduction of novel drug delivery modalities like patient-controlled epidural analgesia (PCEA) pumps and computer-integrated drug delivery pumps have improved the overall maternal satisfaction rate and have enabled us to customize a suitable analgesic regimen for each parturient. Recent randomized controlled trials and Cochrane studies have concluded that the association of epidurals with increased caesarean section and long-term backache remains only a myth. Studies have also shown that the newer, low-dose regimes do not have a statistically significant impact on the duration of labour and breast feeding and also that these reduce the instrumental delivery rates thus improving maternal and foetal safety. Advances in medical technology like use of ultrasound for localizing epidural space have helped the clinicians to minimize the failure rates, and many novel drug delivery modalities like PCEA and computer-integrated PCEA have contributed to the overall maternal satisfaction and safety.

    The addition of opioids to epidural local anesthetic reduces local anesthetic consumption by 20% but at the expense of side effects and time spent for regulatory compliance paperwork. Epidural neostigmine also reduces local anesthetic use. The authors hypothesized that epidural bupivacaine with neostigmine would decrease total hourly bupivacaine use compared with epidural bupivacaine with fentanyl for patient-controlled epidural analgesia. A total of 215 American Society of Anesthesiologists physical status II, laboring parturients requesting labor epidural analgesia consented to the study and were randomized to receive 0.125% bupivacaine with the addition of either fentanyl (2 μg/ml) or neostigmine (2, 4, or 8 μg/ml). The primary outcome was total hourly local anesthetic consumption, defined as total patient-controlled epidural analgesia use and top-ups (expressed as milliliters of 0.125% bupivacaine) divided by the infusion duration. A priori analysis determined a group size of 35 was needed to have 80% power at α = 0.05 to detect a 20% difference in the primary outcome. Of 215 subjects consented, 151 patients were evaluable. Demographics, maternal and fetal outcomes, and labor characteristics were similar among groups. Total hourly local anesthetic consumption did not differ among groups (P = 0.55). The total median hourly bupivacaine consumption in the fentanyl group was 16.0 ml/h compared with 15.3, 14.6, and 16.2 ml/h in the 2, 4, and 8 μg/ml neostigmine groups, respectively (P = 0.55). The data do not support any difference in bupivacaine requirements for labor patient-controlled epidural analgesia whether patients receive epidural bupivacaine with 2 to 8 μg/ml neostigmine or epidural bupivacaine with 2 μg/ml fentanyl.

    This study was designed to compare the effects of dexketoprofen, lornoxicam, and diclophenac sodium on postoperative analgesia and tramadol consumption in patients receiving postoperative patient-controlled tramadol after a major abdominal surgery. Eighty patients were randomized to receive one of the four study drugs. Patients in group dexketoprofen (DT) received IV 50 mg dexketoprofen, group lornoxicam (LR) received IV 8 mg lornoxicam, group diclophenac sodium (DS) received 75 mg IV diclophenac sodium and group saline (S) received 0.9% saline in 2 mL syringes, 20 min before the end of anaesthesia. A standardized (1 mg kg(-1)) dose of tramadol was routinely administered to all patients as the loading dose at the end of surgery. Postoperatively, whenever patients requested, they were allowed to use a tramadol patient-controlled analgesia device giving a bolus dose (0.2 mg kg(-1)) of tramadol. Pain, discomfort, and sedation scores, cumulative tramadol consumption, supplemental meperidine requirement, and side effects were recorded. Visual rating scale and patient discomfort scores were significantly lower in DT, LR and DS groups compared to those in in group S (pdexketoprofen to patient-controlled tramadol resulted in lower pain scores, smaller tramadol consumption, less rescue supplemental analgesic requirement, and fewer side effects compared with the tramadol alone group.

    The aim of this study was to evaluate the effect of inflatable obstetric belts on uterine fundal pressure in the management of the second stage of labor. Between July 2009 and December 2010, 188 nulliparous women with a singleton pregnancy at term were enrolled and only one dropped. The participants were randomized to receive either standard care (control group, n = 91) or uterine fundal pressure by the Labor Assister (Baidy M-520/Curexo, Inc., Seoul, Korea; active group, n = 97) during the second stage of labor in addition to standard care. The Labor Assister is an inflatable obstetric belt that is synchronized to apply constant fundal pressure during a uterine contraction. The primary endpoint was duration of the second stage of labor in women who delivered vaginally (control, n = 80 versus active, n = 93). It was not analyzed in women who delivered by cesarean section (n = 14) and delivered precipitously (n = 1). The secondary outcomes are perinatal outcomes and perineal laceration. Participants received patient-controlled epidural analgesia. The 93 women in the active group spent less time in the second stage of labor when compared to the 80 women in the control group (46.51 ± 28.01 min versus 75.02 ± 37.48 min, p labor without complications in nulliparous women who receive patient-controlled epidural analgesia.

    2013-06-01

    Conclusion: In this study, we successfully demonstrated that our IVPCA protocol can provide adequate analgesia for patients after both bilateral and unilateral TKA. However, sedation, nausea, and vomiting occurred more frequently during the postoperative 24–48-hour period in patients who underwent bilateral than unilateral TKA. This may due of the increased number of bolus doses administered to the patients in the bilateral TKA group during the postoperative 12–18, 18–24, and 30–36-hour periods. Therefore, the initial infusion rates for patients undergoing bilateral TKA could be set at a lower threshold in order to reduce the incidence of these side effects.

    Problems like postoperative pain are still common phenomena after general anesthesia. Oxycodone hydrochloride is a semisynthetic opioid with a safe and excellent therapeutic effect on visceral pain. Flurbiprofen axetil has the efficacy of targeted analgesia. We hypothesize that different doses of oxycodone hydrochloride combined with flurbiprofen axetil would generate great results on postoperative intravenous analgesia in lower abdominal patients. In the clinical trial, 90 American Society of Anesthesiologists I or II patients scheduled for elective general anesthesia were randomly divided into 3 groups, 30 cases in each group. Group I: oxycodone hydrochloride 0.5 mg/kg + flurbiprofen axetil 150 mg, group II: oxycodone hydrochloride 0.75 mg/kg + flurbiprofen axetil 150 mg, group III: oxycodone hydrochloride 1.0 mg/kg + flurbiprofen axetil 150 mg. Dilute them with 0.9% saline to 150 mL, respectively, with the background dose of 2 mL/h, patient-controlled analgesia 2 mL per time, with an interval of 10 min, and the loading dose of 0.1 mL/kg. Record the preoperative situation, 24 h (T0) before surgery, postoperative situation, 1 h (T1), 4 h (T2), 8 h (T3), 12 h (T4), 24 h (T5), 48 h (T6), 72 h (T7) after the surgery, including the mean arterial pressure, heart rate, saturation of pulse oximetry, static and dynamic pain rating (NRS) and Ramsay sedation score, effective pressing and total pressing ratio (referred to as the pressing ratio), patient satisfaction, and occurrence of adverse reactions.

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

We systematically searched six databases up to June 2, 2015 for randomized controlled trials (RCTs) comparing ketamine plus morphine/hydromorphone PCA vs morphine/hydromorphone PCA for postoperative pain in adults. Thirty-six RCTs including 2,502 patients proved eligible, and 22 of these were at low risk of bias. The addition of ketamine to morphine/hydromorphone PCA decreased postoperative pain intensity at six to 72 hr when measured at rest (weighted mean difference [WMD] on a 10-cm visual analogue scale ranged from -0.4 to -1.3 cm) and during mobilization (WMD ranged from -0.4 to -0.5 cm). Adjunctive ketamine also significantly reduced cumulative morphine consumption at 24-72 hr by approximately 5-20 mg. Predefined subgroup analyses and meta-regression did not detect significant differences across subgroups, including a dose-response relationship. There was no significant difference in patient satisfaction scores at 24 and 48 hr. Nevertheless, the addition of ketamine to morphine/hydromorphone PCA significantly reduced postoperative nausea and vomiting (relative risk, 0.71; 95% confidence interval [CI], 0.60 to 0.85; absolute risk reduction, 8.9%; 95% CI, 4.6 to 12.2). Significant effects on other adverse events (e.g., hallucinations, vivid dreams) were not detected, though only a few studies reported on them. Adding ketamine to morphine/hydromorphone PCA provides a small improvement in postoperative analgesia while reducing opioid requirements. Adjunctive ketamine also reduces postoperative nausea and vomiting without a detected increase in other adverse effects; however, adverse events were probably underreported.

    Patient-controlled epidural analgesia (PCEA) has gained popularity, but it is still unclear whether adding a background infusion confers any benefit. A systematic literature search in PubMed, Embase, CINAHL, LILACS, CENTRAL, Clinicaltrials.gov, and ISI WOS was performed to identify randomized controlled double-blind trials that compare PCEA-only with PCEA combined with a continuous infusion (PCEA + CI) in parturients. The data were subjected to meta-analyses using the random-effects model. Our primary outcome was the incidence of instrumental vaginal delivery. Secondary outcomes were incidences of spontaneous vaginal and cesarean deliveries, duration of labor, analgesic outcomes, maternal outcomes (visual analog scale scores for pain, maternal satisfaction, nausea, pruritus, hypotension), and neonatal outcomes (Apgar score, umbilical artery pH). We identified 7 trials with a low risk of bias, reporting on 891 parturients, for inclusion in our systematic review. The risk of instrumental vaginal delivery was increased in the PCEA + CI group, risk ratio (RR) 1.66 (95% confidence interval 1.08-2.56, P = 0.02; I = 0%); the RR for cesarean delivery was 0.83 (95% confidence interval 0.61-1.13, I = 0%). The second stage of labor was prolonged (weighted mean difference 12.3 minutes, 95% confidence interval 5.1-19.5 minutes, P = 0.0008; I = 0%) in the PCEA + CI group. Fewer patients in the PCEA + CI group required physician-administered boluses (RR 0.35 [95% confidence interval 0.25-0.47, P neonatal outcomes (Apgar scores analgesia. Further high-quality studies involving a sufficient number of patients are required.

    This study was to investigate the physical and chemical compatibility of butorphanol with tramadol or fentanyl in 0.9% sodium chloride injections for patient controlled analgesia administration. The solutions were prepared in polyvinyl chloride (PVC) infusion bags and stored without protected from light exposure at room temperature (25 degrees C) or refrigerated (4 degrees C). Over a period of 168 hours, stabilities were determined by visual inspection, pH measurement, and high-pressure liquid chromatography (HPLC) assay of drug concentrations. At both temperatures, admixtures of butorphanol-tramadol and butorphanol-fentanyl were clear in appearance, and no color change or precipitation was observed during the study period. The maximum losses obtained were lower than 5% for the three drugs after 168 hours of storage. The results indicate that, at ambient or refrigerated storage conditions, the drug mixtures of butorphanol-tramadol and butorphanol-fentanyl in 0.9% sodium chloride injections were physically and chemically stable for at least 168 hours when stored in PVC syringes.

    This study aimed to develop a multimedia video CD (VCD) of patient-controlled analgesia (PCA) and test its effects on pain knowledge and pain relief in patients receiving surgery. This multimedia VCD of PCA was created to convey fundamental knowledge to both patients and their family members and help patients properly utilize PCA devices to relieve pain and improve recovery. The content of multimedia VCD of PCA included pre-admission pain education, introduction of PCA, nursing care procedures, and questions and answers. This study used a quasi-experimental research design to test effects of the multimedia education program in the experimental group of 30 subjects compared to the control subjects of equal number (without the multimedia VCD of PCA). (1) The intervention of multimedia VCD of PCA resulted in a statistically significant difference in pain knowledge between the experimental and control groups. (2) Subjects in the experimental group obtained a better outcome of pain relief compared to control subjects. (3) Subjects in the experimental group indicated that the multimedia VCD of PCA indeed helped them effectively operate their PCA devices to relieve surgery pain. The clinical application of the multimedia VCD of PCA could help patients improve knowledge on pain, learn how to use PCA devices, achieve proper pain relief, and increase effectiveness of recovery activities.

    To alleviate stinging pain in the skin entry area and visceral discomfort in patients who are undergoing ESWL. This study was designed to investigate the effectiveness of the EMLA cream in combination with remifentanil patient-controlled analgesia (PCA) in patients undergoing ESWL treatment. Sixty patients were divided into two double-blind randomized groups. Those in the first group were administered 3-5mm of EMLA 5% cream on a marked area; the second group received, as a placebo, a cream with no analgesic effect in the same amount. All patients were administered a remifentanil bolus with a PCA device. Arterial blood pressure, oxygen saturation, and respiratory rate were recorded throughout the procedure; postoperative side effects, agitation, and respiratory depression were measured after. Visual Analogue Scale (VAS) scores were taken preoperatively, perioperatively, directly postoperatively, and 60 minutes subsequent to finishing the procedure. There were no statistically significant differences in the frequency of PCA demands and delivered boluses or among perioperative VAS. No significant side effects were noted. Patient satisfaction was recorded high in both groups. EMLA cream offered no advantage over the placebo cream in patients undergoing ESWL with remifentanil PCA.

    Opioid analgesics administered by patient-controlled analgesia (PCA) are frequently used for pain relief in children and adults with sickle cell disease (SCD) hospitalized for persistent vaso-occlusive pain, but optimum opioid dosing is not known. To better define PCA dosing recommendations, a multi-center phase III clinical trial was conducted comparing two alternative opioid PCA dosing strategies (HDLI-higher demand dose with low constant infusion or LDHI- lower demand dose and higher constant infusion) in 38 subjects who completed randomization prior to trial closure. Total opioid utilization (morphine equivalents, mg/kg) in 22 adults was 11.6 ± 2.6 and 4.7 ± 0.9 in the HDLI and in the LDHI arms, respectively, and in 12 children it was 3.7 ± 1.0 and 5.8 ± 2.2, respectively. Opioid-related symptoms were mild and similar in both PCA arms (mean daily opioid symptom intensity score: HDLI 0.9 ± 0.1, LDHI 0.9 ± 0.2). The slow enrollment and early study termination limited conclusions regarding superiority of either treatment regimen. This study adds to our understanding of opioid PCA usage in SCD. Future clinical trial protocol designs for opioid PCA may need to consider potential differences between adults and children in PCA usage. PMID:21953763

    This study evaluated the efficacy of patient-controlled analgesia (PCA) used by children with sickle cell anemia (SCA) based on the attitudes of parents and healthcare professionals. A total of 86 individuals were involved in the study: 54 parents of children with SCA who were receiving treatment and 32 healthcare providers (doctors, nurses). To evaluate the effectiveness of the PCA method, a questionnaire was prepared to determine the level of knowledge of the participants about the PCA method and their perception of its advantages and disadvantages. According to 65.6% (n=21) of the healthcare providers, PCA should be used during acute phase of pain. The great majority of the participants (93%; n=80) thought that pain was effectively controlled both during the day and at night. PCA reduced the fear of unavailability of analgesic drugs in 83.3% (n=45) of parents and in 87.5% (n=28) of healthcare providers. More parents (37%) reported a reduction in the fear of return of pain than healthcare providers (9.4%) (paddiction. Resolving machine alarms (48%; n=26) and the length of time required to refill the machine (48%; n=26) were reported as disadvantages of PCA method. In this study, parents and healthcare professionals found PCA to be effective in relieving pain in children with SCA; however, fears and biased knowledge of users about the analgesic drug are thought to inhibit reaching sufficient dosage. Educational courses for users about PCA and the drugs used may increase the effectiveness of PCA method.

    The commonest opioid used for pain relief in labour is pethidine (meperidine); however, its effectiveness has long been challenged and the drug has known side effects including maternal sedation, nausea and potential transfer across the placenta to the foetus. Over a third of women receiving pethidine require an epidural due to inadequate pain relief. Epidural analgesia increases the risk of an instrumental vaginal delivery and its associated effects. Therefore, there is a clear need for a safe, effective, alternative analgesic to pethidine. Evidence suggests that remifentanil patient-controlled analgesia (PCA) reduces epidural conversion rates compared to pethidine; however, no trial has yet investigated this as a primary endpoint. We are, therefore, comparing pethidine intramuscular injection to remifentanil PCA in a randomised controlled trial. Women in established labour, requesting systemic opioid pain relief, will be randomised to either intravenously administered remifentanil PCA (intervention) or pethidine intramuscular injection (control) in an unblinded, 1:1 individual randomised trial. Following informed consent, 400 women in established labour, who request systemic opioid pain relief, from NHS Trusts across England will undergo a minimised randomisation by a computer or automated telephone system to either pethidine or remifentanil. In order to balance the groups this minimisation is based on four parameters; parity (nulliparous versus multiparous), maternal age (Asian (Pakistani/Indian/Bangladeshi) versus Other) and induced versus spontaneous labour. The effectiveness of pain relief provided by each technique will be recorded every 30 min after time zero, until epidural placement, delivery or transfer to theatre, quantified by Visual Analogue Scale. Incidence of maternal side effects including sedation, delivery mode, foetal distress requiring delivery, neonatal status at delivery and rate of initiation of breastfeeding within the first hour of birth

    Selection of the best analgesic technique in patients undergoing major surgeries can result in lower morbidity and satisfactory postoperative pain relief. In the present study, we tried to compare the effect of morphine and sufentanil on postoperative pain severity and hemodynamic changes by using patient-controlled analgesia (PCA) device in patients who were candidate for coronary artery bypass surgery (CABG). It was a randomized double-blinded clinical trial in which 120 patients aged 30-65 years, ASA physical status I-III, candidate for CABG in Shahid Rajaee hospital in Tehran were included. Before anesthesia, patients were randomly assigned to one of three groups to receive sufentanil (n=40), morphine (n=40) or normal saline (n=40). After tracheal extubation at intensive care unit, PCA was started by, sufentanil 4mg for the first group, morphine 2mg for the second group and normal saline, at same volume for the third group, intravenously with 10 minute lockout interval. Postoperative pain was evaluated by VAS scale, 1, 6, 12, 18 and 24 hours after extubation and systolic blood pressure, arterial oxygen saturation, PCO2 and PO2 were recorded 24 hours after extubation. VAS scores at rest revealed significantly less pain for patients in sufentanil and morphine groups than normal saline group, throughout the twenty-four hours after operation (P<0.001). However, there were no significant differences in the means of VAS scores between sufentanil and morphine groups. Among studied hemodynamic parameters, only systolic blood pressure was reduced more in morphine than sufentanil group (P<0.001). After CABG surgery, administration of intravenous sufentanil and morphine using PCA can lead to similar reduction of postoperative pain severity. (author)

    There is no information about the distribution of pethidine into breast milk and/or exposure of the breastfed infant during pethidine patient-controlled epidural analgesia after caesarean delivery. We conducted an observational study among 20 women. The mean (95% confidence interval) pethidine dose administered was 670 (346-818) mg over 41 (35-46) h. Maternal plasma and milk and neonatal plasma were collected near the time of pethidine cessation and 6h later. Absolute and relative infant doses via milk and infant exposure were calculated. Infant behaviour was assessed using the Neurologic and Adaptive Capacity Score. At first and second sampling times, mean absolute infant doses for pethidine were 20 (14-27) μg/kg/day and 10 (7-13) μg/kg/day, while mean relative infant doses were 0.7 (0.1-1.4)% and 0.3 (0.1-0.5)% respectively. Similar values for norpethidine (expressed as pethidine equivalents) were 21 (16-26) μg/kg/day and 22 (12-32) μg/kg/day; and 0.7 (0.3-1)% and 0.6 (0.2-1)% respectively. Mean pethidine and norpethidine concentrations in neonatal plasma were 3 (0-6.1) μg/L and 0.6 (0.2-1) μg/L. Compared with a time-matched maternal sample, the infant's exposure was 1.4 (0.2-2.8)% for pethidine and 0.4 (0.2-0.6)% for norpethidine. The mean (95% confidence interval) neurologic and adaptive capacity score was 33.6 (32.2-34.9). The combined absolute infant dose of pethidine and norpethidine received via milk was 1.8% of the neonatal therapeutic dose and the combined relative infant dose was below the 10% recommended safety level. Breastfed infants are at low risk of drug exposure when mothers self-administer epidural pethidine after caesarean delivery. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Because newer anticoagulation strategies for total knee replacement present potentially increased risk of neuraxial analgesia, there is movement away from using patient-controlled epidural analgesia (PCEA) for pain control. This concern opens the door for other regional modalities in postoperative analgesia, including the use of extended-release epidural morphine (EREM) combined with a femoral nerve block (FNB). This study was a prospective observational chart review with the use of recent historical controls in patients undergoing unilateral total knee replacement. Outcomes of interest were 0-, 24-, and 48-hour postoperative pain scores using the visual analog scale (VAS); incidence of side effects; and time spent in the postanesthesia care unit (PACU). Postoperative pain scores at 24 and 48 hours in the EREM and FNB group (n  =  14; 2.6 ± 0.6 and 5.0 ± 0.9, respectively) were comparable to the PCEA group (n  =  14; 3.8 ± 0.6 and 4.2 ± 0.9). The PACU time was shorter in the EREM and FNB group (2.4 ± 0.3 hours) compared with PCEA (3.6 ± 0.3 hours, P  =  .02). No statistically significant difference was found in the incidence of side effects between the 2 groups. The VAS scores at 24 and 48 hours indicate that EREM and FNB provide comparable analgesia to PCEA. The trend toward shorter PACU times represents an opportunity for cost-identification analysis. The study data are limited by their observational nature and the small number of patients involved; nevertheless, this study demonstrates a therapeutic equivalence to PCEA that may be more cost effective.

    Ketamine is often added to opioids in patient-controlled analgesia devices. We tested whether in surgical patients, ketamine added to an opioid patient-controlled analgesia decreased pain intensity by ≥25%, cumulative opioid consumption by ≥30%, the risk of postoperative nausea and vomiting by ≥30%, the risk of respiratory adverse effects by ≥50%, and increased the risk of hallucination not more than 2-fold. In addition, we searched for evidence of dose-responsiveness. Nineteen randomized trials (1349 adults, 104 children) testing different ketamine regimens added to various opioids were identified through searches in databases and bibliographies (to 04.2016). In 9 trials (595 patients), pain intensity at rest at 24 hours was decreased by 32% with ketamine (weighted mean difference -1.1 cm on the 0-10 cm visual analog scale [98% CI, -1.8 to -0.39], P ketamine (weighted mean difference -12.9 mg [-22.4 to -3.35], P = 0.002). In 7 trials (435 patients), the incidence of postoperative nausea and vomiting was decreased by 44% with ketamine (risk ratio 0.56 [0.40 to 0.78], P ketamine on pain intensity, cumulative morphine consumption, and postoperative nausea and vomiting and its inability to double the risk of hallucination. The available data did not allow us to make a conclusion on respiratory adverse events or to establish dose-responsiveness.

    Objective To compare the characteristics of ropivacaine with bupivacaine for postoperative patient-controlled epidural analgesia(PCEA).Method Sixty epidural anesthesia patients (ASA Ⅰ~Ⅱ ) scheduled for low abdominalsurgery were divided into two groups randomly to receive 0.125% ropivacaine or0.125% bupivacaine for postoperative patient-controlled epidural analgesia respectively. A bolus doses of 5ml with 30min lockout and a continuous dose of 2ml/h weregiven within 48 hours after surgery. Analgesic efficacy was assessed using 100mm visual analog pain scores (VAS) ,and motorblock was assessed using Bromage score. Volume of the epidural infusion and number of patients requesting supplementaryanalgesics were recorded. Result There were no significant differences between groups in pain scores, volume of the epiduralinfusion and number of patients requesting supplementary analgesics (P > 0.05). But there was higher incidence of zeroBromage score at some time and mobilization recovered more quickly in ropivacaine group. Conclusion Comparing withbupivacaine,0. 125 % ropivacaine may produce equivalent anaglesia, less motor block and early recovery of mobilization forpostoperative (PCEA).

    Tumescent anaesthesia (TA) is an important but sometimes very painful step during endovenous thermal ablation of incompetent veins. The aim of this study was to examine whether the use of fixed 50% nitrous oxide/oxygen mixture (N2O/O2), also called equimolar mixture of oxygen and nitrous oxide, reduces pain during the application of TA. Patients undergoing endovenous laser ablation (EVLA) of incompetent saphenous veins were included. Thirty consecutive patients inhaled N2O/O2 during the application of TA. Thirty consecutive patients received TA alone (controls). Patients were asked to complete a questionnaire immediately after the intervention to assess satisfaction with the intervention and pain-levels during the different steps of the intervention (0=not at all, 10=very much). Adverse events during the treatment were monitored. 30 patients (14 men, mean age of 44 years) were included in the N2O/O2 group and 30 patients (9 men, mean age 48 years) were included in the control group. In the N2O/O2 group a significantly lower pain score was noted (mean 2.45 points, range 0-6) compared to the controls (mean 4.3 points, range 1-9, p<0.001). Overall, 64.5% of the patients were perfectly satisfied with the N2O/O2-Inhalation. Only 4 patients receiving N2O/O2 complained of adverse effects such as unpleasant loss of control (2 patients), headache (1 patient) and dizziness (1 patient). N2O/O2 is a safe and effective method to reduce pain during the application of tumescent anaesthesia for EVLA.

    Postoperative nausea and vomiting (PONV) is the most common postoperative complication. The postoperative use of opioids is known to increase the incidence. We compared fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, and ondansetron for their preventive effects on PONV in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia. This prospective, double-blind, randomized study comprised 44 patients who underwent gynecologic abdominal surgery. They were randomly allocated to receive 150 mg intravenous fosaprepitant (n = 24; NKI group) or 4 mg ondansetron (n = 20; ONS group) before anesthesia, which was maintained with volatile anesthetics, remifentanil, fentanyl, and rocuronium. All patients received postoperative fentanyl by patient-controlled epidural anesthesia. The incidence of nausea and vomiting, complete response rate (i.e., no vomiting and no rescue antiemetic use), rescue antiemetic use, nausea score (0-3), and visual analog scale score (VAS 0-10) for pain were recorded at 2, 24, 48, and 72 h after surgery. No (0 %) patient in the NKI group experienced vomiting after surgery; however, 4-6 (20-30 %) of 20 patients in the ONS group experienced vomiting. This difference was significant at 0-24, 0-48, and 0-72 h. During the study period, no significant differences existed between the NK1 and ONS groups in the incidence of PONV, complete response rate, rescue antiemetic use, nausea score, and VAS score for pain. Compared to ondansetron, fosaprepitant more effectively decreased the incidence of vomiting in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia.

    The aim of this meta-analysis was to compare the ease of care (EOC) of fentanyl iontophoretic transdermal system (ITS) vs the morphine intravenous patient-controlled analgesia (IV PCA) as assessed by the nurse. Meta-analysis of three phase 3B randomized active-comparator trials. This meta-analysis according to Cochrane's approach assessed EOC using a validated nurse questionnaire (22 items grouped into three subscales, which include time efficiency, convenience, and satisfaction) in adult patients treated with fentanyl ITS or morphine IV PCA for postoperative pain management. The weighted mean difference (WMD) between treatments was calculated. EOC analyses were based on responses to questionnaires from 848 (fentanyl ITS) and 761 (morphine IV PCA) nurses. Fentanyl ITS was reported to provide significant advantages compared with morphine IV PCA in terms of nurses' overall EOC (WMD = -0.57, P PCA.

The aim of this study was to compare postoperative analgesia provided by epidural fentanyl or sufentanil, in bolus or continuous infusion, in patients submitted to knee ligament reconstruction. METHODS: Seventy ASA I - II patients, aged 16 to 47 years, were randomly distributed in two groups. All patients were submitted to epidural anesthesia with 0.5% bupivacaine (100 mg with epinephrine 1:200,000 associated to fentanyl (100 mg. At the end of the procedure, patients received epidural fentanyl (Group F or sufentanil (Group S in continuous infusion plus patient controlled boluses. Group F infusion solution was made of saline (85 ml, 500 µg fentanyl (10 ml and 0.5% bupivacaine (5 ml. Group S solution was made of saline (92 ml, 150 µg sufentanil (3 ml and 0.5% plain bupivacaine (5 ml. Infusion pump´s flow was initially programmed to 5 ml.h-1, with 2 ml patient controlled bolus doses every 15 minutes at most, for both groups. The following parameters were compared: pain, number of patient controlled boluses, opioid consumption, motor block, sedation and side-effects. RESULTS: There have been no statistically

    Objective To study the effects of patient-controlled epidural analgesia (PCEA) with morphine and bupivacaine on gastrointestinal function recovery after operation. Methods Two-hundred and forty patients undergoing elective abdominal surgery were divided into 5 groups, and patients in groupsⅠto Ⅲ received PCEA with bupivacaine and morphine postoperatively, while patients in groups Ⅳ and Ⅴ received no analgesia after operation. The Visual Analogue Scale (VAS) 24 h after the operation was adopted and the time of first flatus noted. Results For upper abdominal surgery, the effects of PCEA with bupivacaine combined with morphine were better than that with bupivacaine alone, while for lower abdominal surgery, bupivacaine alone was enough. PCEA with bupivacaine and morphine did not delay the time of first flatus after surgery. Conclusion PCEA with bupivacaine and morphine do not delay the time for gastrointestinal function recovery in patients.%目的 观察术后病人应用自控硬膜外镇痛(PCEA)的镇痛效应及其对胃肠功能的影响。方法 将240例腹部手术病人随机分为5组,Ⅰ~Ⅲ组病人术后应用不同药物配方和剂量的PCEA,Ⅳ、Ⅴ组病人术后无镇痛,记录其术后24 h视觉模拟评分(Visual analogue scale,VAS)及首次肛门排气时间。结果 对于上腹部手术,术后 PCEA联合用吗啡和布比卡因效果较好;对于下腹部手术,术后单用布比卡因PCEA即可。全部病人术后首次肛门排气时间无显著延长。结论 对于60岁以下的病人,术后适量吗啡、布比卡因PCEA效果好,不延长术后胃肠功能恢复的时间。

    Acute pain is a common complication following cesarean section under general anesthesia. Post-cesarean section pain management is important for both the mother and the newborn. This study compared the effects of patient-controlled intravenous analgesia (PCIA) using sufentanil or tramadol on postoperative pain control and initiation time of lactation in patients who underwent cesarean section under general anesthesia. Primiparas (n=146) scheduled for cesarean section under general anesthesia were randomized to receive PCIA with sufentanil or tramadol. Movement-evoked and rest-pain intensity were assessed by the Numerical Rating Scale (NRS) postoperatively. The number of PCIA attempts, amount of drug consumed, initiation time of lactation, and Quality of Recovery Score 40 (QoR-40) were recorded at 4, 8, 12, and 24 h postoperatively. Pre- and postoperative serum prolactin levels were recorded. No between-group difference existed in the NRS at rest at any time point postoperatively. Patients on sufentanil had more movement-evoked pain and a higher sedation score at 4, 8, and 12 h postoperatively, as compared with the tramadol group. At 24 h, the QoR-40 was higher in the tramadol group compared with the sufentanil group. No significant between-group differences were present in patient satisfaction and nausea/vomiting scores. Postpartum prolactin levels were significantly higher in the tramadol group versus the sufentanil group, corresponding with a significant delay in initiation of lactation in the latter. PCIA with tramadol may be preferred due to lower movement-evoked pain, higher quality of recovery, and earlier lactation in patients following cesarean section under general anesthesia.

    2011-01-01

    With the increasing popularity of rabbits as household pets, the complexity of diagnostic and surgical procedures performed on rabbits is increasing, along with the frequency of routine surgical procedures. More practitioners are faced with the need to provide adequate analgesia for this species. Preemptive analgesia prior to planned surgical interventions may reduce nervous system changes in response to noxious input, as well as reduce postoperative pain levels and analgesic drug requirements. Concurrent administration of analgesic drugs to anesthetized rabbits undergoing painful procedures is warranted both pre- and intraoperatively as well as postoperatively. This article discusses the neuropharmacologic and pharmacologic aspects of pain in rabbits, and reviews current protocols for the use of analgesic drugs. Published by Elsevier Inc.

    BACKGROUND AND OBJECTIVE: The last 25 years have seen changes in the management of epidural analgesia for labour, including the advent of low-dose epidural analgesia, the development of new local anaesthetic agents, various regimes for maintaining epidural analgesia and the practice of combined spinal-epidural analgesia. We conducted a survey of Irish obstetric anaesthetists to obtain information regarding the conduct and management of obstetric epidural analgesia in Ireland in 2005. The specific objective of this survey was to discover whether new developments in obstetric anaesthesia have been incorporated into clinical practice. METHODS: A postal survey was sent to all anaesthetists with a clinical commitment for obstetric anaesthesia in the sites approved for training by the College of Anaesthetists, Ireland. RESULTS: Fifty-three per cent of anaesthetists surveyed responded. The majority of anaesthetists (98%) use low-dose epidural analgesia for the maintenance of analgesia. Only 11% use it for test-dosing and 32% for the induction of analgesia. The combined spinal-epidural analgesia method is used by 49%, but two-thirds of those who use it perform fewer than five per month. Patient-controlled epidural analgesia was in use at only one site. CONCLUSION: It appears that Irish obstetric anaesthetists have adopted the low-dose epidural analgesia trend for the maintenance of labour analgesia. This practice is not as widespread, however, for test dosing, the induction of analgesia dose or in the administration of intermittent epidural boluses to maintain analgesia when higher concentrations are used. Since its introduction in 2000, levobupivacaine has become the most popular local anaesthetic agent.

    Full Text Available The number of noninvasive and minimally invasive procedures performed outside of the operating room has grown exponentially over the last several decades. Sedation, analgesia, or both may be needed for many of these interventional or diagnostic procedures. Individualized care is important when determining if a patient requires procedural sedation analgesia (PSA. The patient might need an anti-anxiety drug, pain medicine, immobilization, simple reassurance, or a combination of these interventions. The goals of PSA in four different multidisciplinary practices namely; emergency, dentistry, radiology and gastrointestinal endoscopy are discussed in this review article. Some procedures are painful, others painless. Therefore, goals of PSA vary widely. Sedation management can range from minimal sedation, to the extent of minimal anesthesia. Procedural sedation in emergency department (ED usually requires combinations of multiple agents to reach desired effects of analgesia plus anxiolysis. However, in dental practice, moderate sedation analgesia (known to the dentists as conscious sedation is usually what is required. It is usually most effective with the combined use of local anesthesia. The mainstay of success for painless imaging is absolute immobility. Immobility can be achieved by deep sedation or minimal anesthesia. On the other hand, moderate sedation, deep sedation, minimal anesthesia and conventional general anesthesia can be all utilized for management of gastrointestinal endoscopy.

    Aim: Effective pain management during labour is important because pain affects the birth experience. Epidural analgesia is effective but often it may not be possible; however, inhaled analgesia offers another option. Use of inhaled nitrous oxide and oxygen for pain management in labour is well established in obstetrics but is still not used much in Germany. This study aimed to investigate the acceptance of the inhaled analgesia of inhaled nitrous oxide and oxygen by midwives and pregnant women during labour. Material and Methods: In this observational study carried out between April and September 2013, a total of 66 pregnant women received inhaled nitrous oxide and oxygen during labour on request and after prior assessment of suitability. After the birth, all of the women and the responsible midwives were interviewed about their experience and satisfaction with the inhaled analgesia. Results: A statistically significant reduction of pain was achieved with nitrous oxide and oxygen. The inhaled analgesia was mostly used by women who refused epidural analgesia. The likelihood of using inhaled nitrous oxide and oxygen again was reported as higher for patients who tolerated it well (p = 0.0129) and used it in the second stage of labour (p = 0.0003) and when bearing down (p = 0.0008). Conclusion: Inhaled nitrous oxide and oxygen is an effective method for pain management during labour and is accepted well by women in labour and by midwives. PMID:25100880

    2012-01-01

    Full Text Available Background: Epidural analgesia is claimed to result in prolonged labor. Previous studies have assessed epidural analgesia vs systemic opioids rather than to parturients receiving no analgesia. This study aimed to evaluate the effect of epidural analgesia on labor duration compared with parturients devoid of analgesia. Methods: One hundred sixty nulliparous women in spontaneous labor at full term with a singleton vertex presentation were assigned to the study. Parturients who request epidural analgesia were allocated in the epidural group, whereas those not enthusiastic to labor analgesia were allocated in the control group. Epidural analgesia was provided with 20 mL bolus 0.5% epidural lidocaine plus fentanyl and maintained at 10 mL for 1 h. Duration of the first and second stages of labor, number of parturients receiving oxytocin, maximal oxytocin dose required for each parturient, numbers of instrumental vaginal, vacuum-assisted, and cesarean deliveries and neonatal Apgar score were recorded. Results: There was no statistical difference in the duration of the active-first and the second stages of labor, instrumental delivery, vacuum-assisted or cesarean delivery rates, the number of newborns with 1-min and 5-min Apgar scores less than 7 between both groups and number of parturients receiving oxytocin, however, the maximal oxytocin dose was significantly higher in the epidural group. Conclusion: Epidural analgesia by lidocaine (0.5% and fentanyl does not prolong labor compared with parturients without analgesia; however, significant oxytocin augmentation is required during the epidural analgesia to keep up the aforementioned average labor duration.

    Remifentanil with appropriate pharmacological properties seems to be an ideal alternative to epidural analgesia during labour. A retrospective cohort study was undertaken to assess the efficacy and safety of remifentanil intravenous patient-controlled analgesia (IVPCA) compared with epidural analgesia. Medical records of 370 primiparas who received remifentanil IVPCA or epidural analgesia were reviewed. Pain and sedation scores, overall satisfaction, the extent of pain control, maternal side effects and neonatal outcome as primary observational indicators were collected. There was a significant decline of pain scores in both groups. Pain reduction was greater in the epidural group throughout the whole study period (0∼180 min) (Panalgesia. And logistic regression analysis demonstrated that nausea, vomiting were associated with oxytocin usage and instrumental delivery, and dizziness was associated to the type and duration of analgesia. Neonatal outcomes such as Apgar scores and umbilical-cord blood gas analysis were within the normal range, but umbilical pH and base excess of neonatus in the remifentanil group were significantly lower. Remifentanil IVPCA provides poorer efficacy on labor analgesia than epidural analgesia, with more sedation on parturients and a trend of newborn acidosis. Despite these adverse effects, remifentanil IVPCA can still be an alternative option for labor analgesia under the condition of one-to-one bedside care, continuous monitoring, oxygen supply and preparation for neonatal resuscitation.

    Epidural analgesia is considered the standard of care but cannot be provided to all patients Liposomal bupivacaine has been approved for field blocks such as transversus abdominis plane (TAP) blocks but has not been clinically compared against other modalities. In this retrospective propensity matched cohort study we thus tested the primary hypothesis that TAP infiltration are noninferior (not worse) to continuous epidural analgesia and superior (better) to intravenous opioid analgesia in patients recovering from major lower abdominal surgery. 318 patients were propensity matched on 18 potential factors among three groups (106 per group): 1) TAP infiltration with bupivacaine liposome; 2) continuous Epidural analgesia with plain bupivacaine; and; 3) intravenous patient-controlled analgesia (IV PCA). We claimed TAP noninferior (not worse) over Epidural if TAP was noninferior (not worse) on total morphine-equivalent opioid and time-weighted average pain score (10-point scale) within first 72 hours after surgery with noninferiority deltas of 1 (10-point scale) for pain and an increase less of 20% in the mean morphine equivalent opioid consumption. We claimed TAP or Epidural groups superior (better) over IV PCA if TAP or Epidural was superior on opioid consumption and at least noninferior on pain outcome. Multivariable linear regressions within the propensity-matched cohorts were used to model total morphine-equivalent opioid dose and time-weighted average pain score within first 72 hours after surgery; joint hypothesis framework was used for formal testing. TAP infiltration were noninferior to Epidural on both primary outcomes (pconsumption (p = 0.37). We did not find noninferiority of Epidural over IV PCA on pain scores (P = 0.13) and nor did we find superiority on opioid consumption (P = 0.98). TAP infiltration with liposomal bupivacaine and continuous epidural analgesia were similar in terms of pain and opioid consumption, and not worse in pain compared with IV PCA

    This article discusses the benefits and limitations of inhalation therapy in horses. Inhalation drug therapy delivers the drug directly to the airways, thereby achieving maximal drug concentrations at the target site. Inhalation therapy has the additional advantage of decreasing systemic side effects. Inhalation therapy in horses is delivered by the use of nebulizers or pressured metered dose inhalers. It also requires the use of a muzzle or nasal mask in horses. Drugs most commonly delivered through inhalation drug therapy in horses include bronchodilators, antiinflammatories, and antimicrobials.

    Expectations of pain relief drive placebo analgesia. Understanding how expectations of improvement trigger distinct biological systems to shape therapeutic analgesic outcomes has been the focus of recent pharmacologic and neuroimaging studies in the field of pain. Recent findings indicate that placebo effects can imitate the actions of real painkillers and promote the endogenous release of opioids and nonopioids in humans. Social support and observational learning also contribute to placebo a...

    Full Text Available The intake of saccharin solutions for relatively long periods of time causes analgesia in rats, as measured in the hot-plate test, an experimental procedure involving supraspinal components. In order to investigate the effects of sweet substance intake on pain modulation using a different model, male albino Wistar rats weighing 180-200 g received either tap water or sucrose solutions (250 g/l for 1 day or 14 days as their only source of liquid. Each rat consumed an average of 15.6 g sucrose/day. Their tail withdrawal latencies in the tail-flick test (probably a spinal reflex were measured immediately before and after this treatment. An analgesia index was calculated from the withdrawal latencies before and after treatment. The indexes (mean ± SEM, N = 12 for the groups receiving tap water for 1 day or 14 days, and sucrose solution for 1 day or 14 days were 0.09 ± 0.04, 0.10 ± 0.05, 0.15 ± 0.08 and 0.49 ± 0.07, respectively. One-way ANOVA indicated a significant difference (F(3,47 = 9.521, P<0.001 and the Tukey multiple comparison test (P<0.05 showed that the analgesia index of the 14-day sucrose-treated animals differed from all other groups.

This result indicates that the analgesic effect of sucrose depends on the time during which the solution is consumed and extends the analgesic effects of sweet substance intake, such as saccharin, to a model other than the hot-plate test, with similar results. Endogenous opioids may be involved in the central regulation of the sweet substance-produced analgesia.

    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

    The analgesia/nociception index (ANI) is derived from heart rate variability, ranging from 0 (maximal nociception) to 100 (maximal analgesia), to reflect the analgesia/nociception balance during general anaesthesia. This should be correlated with immediate postoperative pain in the post-anaesthesia care unit (PACU). The aim of this study was to evaluate the performance of ANI measured at arousal from general anaesthesia to predict immediate postoperative pain on arrival in PACU. Two hundred patients undergoing ear, nose, and throat or lower limb orthopaedic surgery with general anaesthesia using an inhalational agent and remifentanil were included in this prospective observational study. The ANI was measured immediately before tracheal extubation and pain intensity was assessed within 10 min of arrival in PACU using a 0-10 numerical rating scale (NRS). The relationship between ANI and NRS was assessed using linear regression. A receiver-operating characteristic (ROC) curve was used to evaluate the performance of ANI to predict NRS>3. A negative linear relationship was observed between ANI immediately before extubation and NRS on arrival in PACU. Using a threshold of 3 were both 86% with 92% negative predictive value, corresponding to an area under the ROC curve of 0.89. The measurement of ANI immediately before extubation after inhalation-remifentanil anaesthesia was significantly associated with pain intensity on arrival in PACU. The performance of ANI for the prediction of immediate postoperative pain is good and may assist physicians in optimizing acute pain management. ClinicalTrials.gov NCT01796249.

    Full Text Available One of the most severe pains experienced by a woman is that of childbirth. Providing analgesia for labor has always been a challenge more so because of the myths and controversies surrounding labor. It is imperative to understand the pain transmission during various stages of labor in order to select a proper technique for providing labor analgesia. The adverse effects of labor pain are numerous and affect both the mother as well as the fetus. Currently lumbar epidural is considered to be the gold standard technique for labor analgesia. Local anaesthetics like bupivacaine and ropivacaine are commonly used and adjuvants like clonidine, fentanyl and neostigmine have been extensively studied. However, despite being so popular, epidural analgesia is not without complications, with hypotension being the most common. Other complications include accidental dural puncture, infection, intravascular placement, high block and epidural hematoma. Other neuraxial techniques include continuous caudal analgesia, and combined spinal epidural analgesia. The numerous studies investigating the various aspects of this method have also served to dispel various myths surrounding epidural analgesia like increased incidence of cesarean section and instrumental delivery, prolongation of labor and future back pain. The future of labor analgesia lies in the incorporation of ultrasound in identifying the epidural space helping in proper catheter placement. The keywords "labor epidural" in the PUBMED revealed a total of 5018 articles with 574 review articles and 969 clinical trials. The relevant articles along with their references were extensively studied.

    To compare analgesia provided by carprofen and tramadol in dogs after enucleation. Randomized, masked clinical trial. 43 dogs. Client-owned dogs admitted for routine enucleation were randomly assigned to receive either carprofen or tramadol orally 2 hours prior to surgery and 12 hours after the first dose. Dogs were scored for signs of pain at baseline (ie, before carprofen or tramadol administration) and at 0.25, 0.5, 1, 2, 4, 6, 8, 24, and 30 hours after extubation. Dogs received identical premedication and inhalation anesthesia regimens, including premedication with hydromorphone. If the total pain score was ≥ 9 (maximum possible score of 20), there was a score ≥ 3 in any of 5 behavioral categories (highest score possible per category was 3 or 4), or the visual analog scale (VAS) score was ≥ 35 (maximum possible score of 100) combined with a palpation score > 0, rescue analgesia (hydromorphone) was administered and treatment failure was recorded. No differences were found in age, sex, or baseline pain scores between groups. Significantly more dogs receiving tramadol required rescue analgesia (6/21), compared with dogs receiving carprofen (1/22). Pain and VAS scores decreased linearly over time. No significant differences were found in pain or VAS scores between groups at any time point (dogs were excluded from analysis after rescue). Results of this study suggested that carprofen, with opioid premedication, may provide more effective postoperative analgesia than tramadol in dogs undergoing enucleation.

    2011-06-01

    Children with chronic or recurrent upper respiratory inflammatory disease (rhinitis) should be considered for inhalant allergies. Risk factors for inhalant allergies in children include a first-degree relative with allergies, food allergy in infancy, and atopic dermatitis. Although inhalant allergies are rare in infancy, inhalant allergies are common in older children and impair quality of life and productivity. Differentiating between viral and allergic rhinitis can be challenging in children, but the child's age, history, and risk factors can provide helpful information. Allergic rhinitis is a risk factor for asthma, and if one is present, medical consideration of the other is warranted. Copyright © 2011 Elsevier Inc. All rights reserved.

    Inhalant abuse is the intentional inhalation of a volatile substance for the purpose of achieving an altered mental state. As an important, yet underrecognized form of substance abuse, inhalant abuse crosses all demographic, ethnic, and socioeconomic boundaries, causing significant morbidity and mortality in school-aged and older children. This review presents current perspectives on epidemiology, detection, and clinical challenges of inhalant abuse and offers advice regarding the medical and mental health providers' roles in the prevention and management of this substance abuse problem. Also discussed is the misuse of a specific "over-the-counter" dissociative, dextromethorphan. Copyright © 2016 Elsevier Inc. All rights reserved.

    2014-01-01

    Full Text Available This work presents a case of a pregnant female dog, of English bulldog breed, three years old, which was brought to Belgrade Faculty of Veterinary Medicine because of inability for normal parturition. Cesarean section is an urgent intervention both in human and in veterinary medicine. Anesthesia of a pregnant dog should be carried out very carefully, because of all the physiological changes that appear during pregnancy, as well as the impact of anesthetics on embryos themselves. Anesthetics, analgesics and sedatives pass through blood brain barrier, but also their transport goes through placenta to embryo, so for that reason it is not possible to anesthetize only mother and to avoid anesthesia effects on the embryo. Therefore, anesthetics with short time of action which metabolize quickly and have minimal negative effect on embryos are recommended. When choosing the right analgesics and anesthetics, there should be known that female dogs in which it is necessary to do Cesarean section belong to the group of high risk patients. Pregnant female dogs are exposed to hypoventilation, hypoxia, hypercapnia, intense heart work, vomiting and regurgitation as well. Reversible anesthetics are recommended to provide shorter duration time of anesthesia, and in accordance, inhalation anesthetics doses are minimal. Application of α2- agonist in premedication, propophol in induction, as well as maintaining general inhalation anesthesia with sevofluran, along with local analgesia, proved to be the ideal combination in this case of cesarean section.

    To assess the outcomes of dental treatment under inhalation sedation within a UK specialist hospital setting. This was a retrospective cohort study of the case notes of patients under 17 years of age who received dental treatment using inhalation sedation at a UK specialist setting during the period 2006-2011. Treatment outcomes were categorised into five groups: (1) treatment completed as planned, (2) modified treatment completed, (3) treatment abandoned in sedation unit and patient referred for treatment under general analgesia (GA), (4) treatment abandoned in sedation unit and patient referred for treatment under local analgesia (LA), (5) child failed to return to complete treatment. In total, the case notes of 453 patients were evaluated. The mean age of the patients was 10.3 ± 2.9 years. Treatment was completed successfully in 63.6% of the cases, 15.9% were referred for treatment under GA, 11.2% failed to return to complete the treatment, 7.1% received modified treatment completed, and only 2.2% were referred for treatment under LA. Treatment outcomes were significantly associated with patient`s age (p = 0.002). The treatment outcome "treatment abandoned and child referred to be treated under GA" had significantly lower mean patient ages than the other outcomes. The majority of children referred for inhalation sedation, completed their course of treatment. A significantly higher proportion of those in the younger age group required GA to complete their treatment.

  2. Objective measurement of inhaler inhalation flow profile using acoustic methods

    Patients with asthma and chronic obstructive pulmonary diseases (COPD) are mostly treated with inhalers that deliver medication directly to their airways. Drug delivery from dry powder inhalers (DPIs) is very much reliant on the inhalation manoeuvre, specifically the peak inspiratory flow rate (PIFR), inspiratory capacity (IC) and inhalation rise time (IRT) of the inhalation. It has been widely reported that patients may not follow correct inhalation technique while using their inhaler. In this study, a novel acoustic method is proposed to accurately estimate inhalation flow profile using only one inhalation recording for calibration. An Ellipta DPI was placed inside an airtight container with a spirometer connected in order to measure inhalation flow parameters. An acoustic recording device (Inhaler Compliance Assessment (INCA)) was also attached to the DPI. Inhalation audio and flow signals were recorded simultaneously. The data were collected from 20 healthy subjects while performing inhaler inhalations at a range of inspiratory flow rates. A power law regression model was computed to obtain the relationship between the acoustic envelope of the inhalation and flow profile of each recording. Each model was tested on the remaining audio signals to estimate flow profile. The average estimation error was found to be 10.5±0.3% for estimating flow profile from audio signals. Inhalation flow profile parameters (PIFR, IC and IRT) could then be measured from the estimated flow profile with high accuracy giving information on user inhalation technique. This method may assist in improving patient inhaler adherence and overall disease control. (Author)

  3. Intravenous remifentanil versus epidural ropivacaine with sufentanil for labour analgesia: a retrospective study.

    Rong Lin

    Full Text Available Remifentanil with appropriate pharmacological properties seems to be an ideal alternative to epidural analgesia during labour. A retrospective cohort study was undertaken to assess the efficacy and safety of remifentanil intravenous patient-controlled analgesia (IVPCA compared with epidural analgesia. Medical records of 370 primiparas who received remifentanil IVPCA or epidural analgesia were reviewed. Pain and sedation scores, overall satisfaction, the extent of pain control, maternal side effects and neonatal outcome as primary observational indicators were collected. There was a significant decline of pain scores in both groups. Pain reduction was greater in the epidural group throughout the whole study period (0 ∼ 180 min (P < 0.0001, and pain scores in the remifentanil group showed an increasing trend one hour later. The remifentanil group had a lower SpO2 (P < 0.0001 and a higher sedation score (P < 0.0001 within 30 min after treatment. The epidural group had a higher overall satisfaction score (3.8 ± 0.4 vs. 3.7 ± 0.6, P = 0.007 and pain relief score (2.9 ± 0.3 vs. 2.8 ± 0.4, P < 0.0001 compared with the remifentanil group. There was no significant difference on side effects between the two groups, except that a higher rate of dizziness (1% vs. 21.8%, P < 0.0001 was observed during remifentanil analgesia. And logistic regression analysis demonstrated that nausea, vomiting were associated with oxytocin usage and instrumental delivery, and dizziness was associated to the type and duration of analgesia. Neonatal outcomes such as Apgar scores and umbilical-cord blood gas analysis were within the normal range, but umbilical pH and base excess of neonatus in the remifentanil group were significantly lower. Remifentanil IVPCA provides poorer efficacy on labor analgesia than epidural analgesia, with more sedation on parturients and a trend of newborn acidosis. Despite these adverse effects, remifentanil IVPCA can still be an alternative

    Timely management of pain in paediatric patients in the Emergency Department (ED) is a well-accepted performance indicator. We describe an audit of the provision of analgesia for children in an Irish ED and the introduction of a nurse-initiated analgesia protocol in an effort to improve performance. 95 children aged 1-16 presenting consecutively to the ED were included and time from triage to analgesia, and the rate of analgesia provision, were recorded. The results were circulated and a nurse initiated analgesia protocol was introduced. An audit including 145 patients followed this. 55.6% of patients with major fractures received analgesia after a median time of 54 minutes, which improved to 61.1% (p = 0.735) after 7 minutes (p = 0.004). Pain score documentation was very poor throughout, improving only slightly from 0% to 19.3%. No child had a documented pain score, which slightly improved to 19.3%. We recommend other Irish EDs to audit their provision of analgesia for children.

    In Peru, the prevalence and consequences of inhalant abuse appear to be low in the general population and high among marginalized children. Inhalant use ranks third in lifetime prevalence after alcohol and tobacco. Most of the use appears to be infrequent. Among marginalized children, that is, children working in the streets but living at home or children living in the street, the problem of inhalant abuse is a serious problem. Among children working in the streets but living at home, the lifetime prevalence rate for inhalant abuse is high, ranging from 15 to 45 percent depending on the study being cited. For children living in the streets, the use of inhalant is even more severe. As mentioned earlier in this chapter, most of these street children use inhalants on a daily basis. The lack of research on the problem of inhalant abuse is a serious impediment to development of intervention programs and strategies to address this problem in Peru. Epidemiologic and ethnographic research on the nature and extent of inhalant abuse are obvious prerequisites to targeted treatment and preventive intervention programs. The urgent need for current and valid data is underscored by the unique vulnerability of the youthful population at risk and the undisputed harm that results from chronic abuse of inhalants. Nonetheless, it is important to mention several programs that work with street children. Some, such as the Information and Education Center for the Prevention of Drug Abuse, Generation, and Centro Integracion de Menores en Abandono have shelters where street children are offered transition to a less marginal lifestyle. Teams of street educators provide the children with practical solutions and gain their confidence, as well as offer them alternative socialization experiences to help them survive the streets and avoid the often repressive and counterproductive environments typical of many institutions. Most of the children who go through these programs tend to abandon

    Full Text Available Procedural sedation and analgesia (PSA is an evolving field in pediatric emergency medicine. As new drugs breach the boundaries of anesthesia in the Pediatric Emergency Department, parents, patients, and physicians are finding new and more satisfactory methods of sedation. Short acting, rapid onset agents with little or no lingering effects and improved safety profiles are replacing archaic regimens. This article discusses the warning signs and areas of a patient′s medical history that are particularly pertinent to procedural sedation and the drugs used. The necessary equipment is detailed to provide the groundwork for implementing safe sedation in children. It is important for practitioners to familiarize themselves with a select few of the PSA drugs, rather than the entire list of sedatives. Those agents most relevant to PSA in the pediatric emergency department are presented.

    Full Text Available Abstract Background and Objective Our objective was to report on the design and essentials of the Etoricoxib protocol- Preemptive and Postoperative Analgesia (EPPA Trial, investigating whether preemptive analgesia with cox-2 inhibitors is more efficacious than placebo in patients who receive either laparotomy or thoracotomy. Design and Methods The study is a 2 × 2 factorial armed, double blinded, bicentric, randomised placebo-controlled trial comparing (a etoricoxib and (b placebo in a pre- and postoperative setting. The total observation period is 6 months. According to a power analysis, 120 patients scheduled for abdominal or thoracic surgery will randomly be allocated to either the preemptive or the postoperative treatment group. These two groups are each divided into two arms. Preemptive group patients receive etoricoxib prior to surgery and either etoricoxib again or placebo postoperatively. Postoperative group patients receive placebo prior to surgery and either placebo again or etoricoxib after surgery (2 × 2 factorial study design. The Main Outcome Measure is the cumulative use of morphine within the first 48 hours after surgery (measured by patient controlled analgesia PCA. Secondary outcome parameters include a broad range of tests including sensoric perception and genetic polymorphisms. Discussion The results of this study will provide information on the analgesic effectiveness of etoricoxib in preemptive analgesia and will give hints on possible preventive effects of persistent pain.

    Epidural and intravenous patient-controlled analgesia (PCA) are established methods for pain relief after total hip arthroplasty (THA). Periarticular infiltration is an alternative method that is gaining ground due to its simplicity and safety. Our study aims to assess the efficacy of periarticular infiltration in pain relief after THA. Sixty-three patients undergoing THA under spinal anaesthesia were randomly assigned to receive postoperative analgesia with continuous epidural infusion with ropivacaine (epidural group), intraoperative periarticular infiltration with ropivacaine, clonidine, morphine, epinephrine and corticosteroids (infiltration group) or PCA with morphine (PCA group). PCA morphine provided rescue analgesia in all groups. We recorded morphine consumption, visual analog scale (VAS) scores at rest and movement, blood loss from wound drainage, mean arterial pressure (MAP) and adverse effects at 1, 6, 12, 24 h postoperatively. Morphine consumption at all time points, VAS scores at rest, 6, 12 and 24 h and at movement, 6 and 12 h postoperatively were lower in infiltration group compared to PCA group (p PCA group (p PCA with morphine after THA, providing better pain relief and lower opioid consumption postoperatively. Infiltration seems to be equally effective to epidural analgesia without having the potential side effects of the latter.

    Full Text Available Adequate post-operative analgesia after caesarean section (CS is vital as it impacts the distinct surgical recovery requirements of the parturient. Although newer analgesic modalities and drugs for post-caesarean analgesia have been introduced over the recent years, review of the literature suggests suggests that we are far from achieving the goals of optimum post-operative analgesia. We conducted a systematic review of recent advances in modalities for post-caesarean analgesia. After systematic search and quality assessment of studies, we included a total of 51 randomised controlled trials that evaluated the role of opioids, transversus abdominis plane (TAP block, wound infiltration/infusion, ketamine, gabapentin and ilioinguinal-iliohypogastric nerve block (II-IH NB for post-caesarean analgesia. Administration of opioids still remains the gold standard for post-operative analgesia, but the associated troublesome side effects have led to the mandatory incorporation of non-opioid analgesics in post-CS analgesia regime. Among the non-opioid techniques, TAP block is the most investigated modality of the last decade. The analgesic efficacy of TAP block as a part of multimodal analgesia is established in post-CS cases where intrathecal morphine is not employed and in CS under general anaesthesia. Among non-steroidal anti-inflammatory drugs, COX-I inhibitors and intravenous paracetamol are found to be useful in post-operative analgesic regimen. The perioperative use of ketamine is found useful only in CS done under spinal anaesthesia; no benefit is seen where general anaesthesia is employed. Wound infiltration with local anaesthetics, systemic gabapentin and II-IH NB need further trials to assess their efficacy.

    This study compared the efficacy of continuous interscalene block (CISB) and subacromial infusion of local anesthetic (CSIA) for postoperative analgesia after open shoulder surgery. This randomized, prospective, double-blinded, single-center study included 40 adult patients undergoing open shoulder surgery. All patients received a standardized general anesthetic. The patients were separated into group CISB and group CSIA. A loading dose of 40 mL 0.25% bupivacaine was administered and patient-controlled analgesia was applied by catheter with 0.1% bupivacaine 5 mL/h throughout 24 h basal infusion, 2 mL bolus dose, and 20 min knocked time in both groups postoperatively. Visual analog scale (VAS) scores, additional analgesia need, local anesthetic consumption, complications, and side effects were recorded during the first 24 h postoperatively. The range of motion (ROM) score was recorded preoperatively and in the first and third weeks postoperatively. A statistically significant difference was determined between the groups in respect of consumption of local anesthetic, VAS scores, additional analgesia consumption, complications, and side effects, with lower values recorded in the CISB group. There were no significant differences in ROM scoring in the preoperative and postoperative third week between the two groups but there were significant differences in ROM scoring in the postoperative first week, with higher ROM scoring values in the group CISB patients. The results of this study have shown that continuous interscalene infusion of bupivacaine is an effective and safe method of postoperative analgesia after open shoulder surgery.

    Full Text Available Background. To evaluate the effects of regional labour analgesia used at the Hospital for Gynecology and Obstetrics in Postojna, Slovenia, in the year 2002.Patients and methods. In this retrospective study we enrolled 294 parturients who delivered in the year 2002 in the Postojna Maternity Hospital: in group 1 there were 147 parturients in whom three different regional analgesic techniques (study group were used at labour; in group 2 there were 147 parturients in whom regional analgesia was not used (control group. In the first step the two groups were compared in terms of maternal demographic data, duration and outcome of labour and 1' and 5' Apgar scores. In the second step the three regional analgesic groups were compared in terms of the course and outcome of labour, fetal condition, side and adverse effects of regional analgesic techniques, and patient satisfaction with a particular analgesic technique.Results. Regional labour analgesia was used in 147 (14% of the 1048 women who delivered in 2002: epidural analgesia (EPI was performed in 51.0%, combined spinal-epidural (CSE in 42.2% and spinal analgesia (SA in 6.8% of cases. The women in the regional analgesia group were significantly older, more educated, more often nulliparous and accompanied by their partner at labour than the women in the control group. Further, the duration of labour was significantly longer, oxytocin more frequently administered than in the control group. In terms of labour outcome there were no differences in the Cesarean section rates and 1- and 5-min Apgar scores minutes, but and the vacuum extraction rate was significantly higher in the regional analgesia group. Among the three regional analgesia techniques used, there were no statistically significant differences observed in terms of labour duration and outcome, and Apgar scores. The patient satisfaction was greatest with CSE. Adverse side effects such as weak muscles, reduced motion abilities, itching, nausea

    The objective of our study is to evaluate the correlation between epidural analgesia during labor, start of breastfeeding and type of maternal-neonatal care.Two different assistance models were considered: Partial and Full Rooming-in.In this cohort study, 2480 healthy infants were enrolled, 1519 in the Partial Rooming-in group and 1321 in the Full Rooming-in group; 1223 were born to women subjected to epidural analgesia in labor.In case of Partial Rooming-in the rate of exclusive or prevailing breastfeeding is significant more frequent in newborns born to mothers who didn't receive analgesia. Instead, in case of Full Rooming-in the rate of exclusive or prevailing breastfeeding is almost the same and there's no correlation between the use or not of epidural analgesia.The good start of lactation and the success of breastfeeding seems to be guaranteed by the type of care offered to the couple mother-infant, that reverses any possible adverse effects of the use of epidural analgesia in labor.

    This project includes experiments to determine the effects of Zn-DTPA therapy on the retention, translocation and biological effects of inhaled 241 AmO 2 . Beagle dogs that received inhalation exposure to 241 AmO 2 developed leukopenia, clincial chemistry changes associated with hepatocellular damage, and were euthanized due to respiratory insufficiency caused by radiation pneumonitis 120 to 131 days after pulmonary deposition of 22 to 65 μCi 241 Am. Another group of dogs that received inhalation exposure to 241 AmO 2 and were treated daily with Zn-DTPA had initial pulmonary deposition of 19 to 26 μCi 241 Am. These dogs did not develop respiratory insufficiency, and hematologic and clinical chemistry changes were less severe than in the non-DTPA-treated dogs

We compared the post-operative analgesic quality of bupivacaine to that of lidocaine for achieving dorsal penile nerve block (DPNB when performing neonatal circumcision. Methods Data were obtained from 38 neonates following neonatal circumcision. The infants had received DPNB analgesia with either lidocaine or bupivacaine. The outcome variable was the administration by the parents of acetaminophen during the ensuing 24 hours. Results Seventeen infants received lidocaine and 19 received bupivacaine DPNB. Ten infants in the lidocaine group (59% were given acetaminophen following circumcision compared to only 3 (16% in the bupivacaine group (P 2 = 20.6; P = 0.006. Conclusion DPNB with bupivacaine for neonatal circumcision apparently confers better analgesia than lidocaine as judged by the requirement of acetaminophen over the ensuing 24-hour period.

    We examined the characteristics of women who choose nitrous oxide for labor analgesia and identified factors that predict conversion from nitrous oxide to labor neuraxial analgesia. Retrospective descriptive study. Labor and Delivery Ward. 146 pregnant women who used nitrous oxide for analgesia during labor and delivery between September 2014 and September 2015. Chart review only. Demographic, obstetric, and intrapartum characteristics of women using nitrous oxide were examined. Multivariable logistic regression was performed to identify factors associated with conversion from nitrous oxide to neuraxial analgesia. Data are presented as n (%), median [IQR], adjusted relative risk (aRR), and 95% confidence intervals (CI) as appropriate. During the study period, 146 women used nitrous oxide for labor analgesia (accounting for 3% of the total deliveries). The majority (71.9%) of women who used nitrous oxide were nulliparous, and over half (51.9%) had expressed an initial preference for "nonmedical birth." The conversion rate to neuraxial blockade was 63.2%, compared to a concurrent institutional rate of 85.1% in women who did not use nitrous oxide. Factors associated with conversion from nitrous oxide to neuraxial blockade were labor induction (aRR=2.0, CI 1.2-3.3) and labor augmentation (aRR=1.7, CI 1.0-2.9). Only a small number of women opted to use nitrous oxide during labor, analgesia was minimal, and most converted to neuraxial analgesia. Women with induced and augmented labors should be counseled about the increased likelihood that they will convert to neuraxial analgesia. Copyright © 2017 Elsevier Inc. All rights reserved.

    2014-02-01

    This study investigated the effectiveness of electroacupuncture analgesia (EAA) at local and paravertebral acupoints for a rabbit undergoing an ovariohysterectomy. Twelve clinically healthy New Zealand white rabbits were chosen and divided into two groups: the control group (5 rabbits) and the experimental group (7 rabbits). A neuroleptanalgesic (ketamine + xylazine) was administered to the control group (NLA group); the experimental group received EAA treatment (EAA group). The EAA treatment includes one acupuncture formula for local stimulation at the incision site and systemic stimulation. Results of clinical research have shown postoperative analgesia using EAA treatment to be superior to that using NLA. The average postoperative recovery time was 5.2 times longer in the NLA group than in the EAA group. Because consciousness was maintained, EAA presented an advantage in thermoregulation. Animals administered NLA had prolonged thermal homeostasis because of neurovegetative disconnection. For the EAA group, the operative times were characterized as excellent (28%, p = 0.28) or good (72%, p = 0.72). Local stimulation at the incision site provided excellent analgesia of the abdominal wall (100%). In conclusion, EA can provide general analgesia with a considerable analgesic effect for a rabbit undergoing an ovariohysterectomy, resulting in a short postoperative recovery time. Copyright © 2014.

    In this study, our aim was to evaluate the effects of intravenous dexketoprofen trometamol with ilioinguinal and iliohypogastric nerve block on analgesic quality and morphine consumption after total abdominal hysterectomy operations. We conducted this randomized controlled clinical study on 61 patients. The study was conducted in the operation room, post-anesthesia care unit, and inpatient clinic. We randomly grouped the 61 patients into control group (group C), block group (group B) and dexketoprofen-block group (group DB). Before the skin incision performed after anesthesia induction, we performed ilioinguinal iliohypogastric block (group C given saline and group P and DB given levobupivacaine). In contrast to group C and B, group DB was given dexketoprofen. We administered morphine analgesia to all patients by patient-controlled analgesia (PCA) during the postoperative 24 hours. We recorded Visual Analogue Scale (VAS), satisfaction scores, morphine consumption and side effects during postoperative 24 hours. We found the DB group's VAS scores to be lower than the control group and block group's (p dexketoprofen increases patient satisfaction by decreasing opioid consumption, increasing patient satisfaction, which suggests that dexketoprofen trometamol is an effective non-steroidal anti-inflammatory analgesic in postoperative analgesia.

    Continuous bilateral thoracic paravertebral blockade has been used for analgesia after cardiac surgery, but its efficacy has never been formally tested. Fifty adult patients were enrolled in a double-blind, randomised, controlled study of continuous bilateral thoracic paravertebral infusion of 0.5% lidocaine (1 mg.kg -1 .hr -1 ) for analgesia after coronary surgery. Control patients received a subcutaneous infusion of lidocaine at the same rate through catheters inserted at the same locations as the study group. The primary outcome was morphine consumption at 48 hours using patient-controlled analgesia (PCA). Secondary outcomes included pain, respiratory function, nausea and vomiting. Serum lidocaine concentrations were measured on the first two post-operative days. There was no difference in morphine consumption or in any other outcome measure between the groups. Serum lidocaine concentrations increased during the study, with a maximum of 5.9 mg.l -1 . There were no adverse events as a consequence of the study. Bilateral paravertebral infusion of lidocaine confers no advantage over systemic lidocaine infusion after cardiac surgery. ISRCTN13424423 ( https://www.isrctn.com ).

    Full Text Available Background: The transverse abdominis plane (TAP block, a regional block provides effective analgesia after lower abdominal surgeries if used as part of multimodal analgesia. In this prospective, randomized double-blind study, we determined the efficacy of TAP block in patients undergoing cesarean section. Materials and Methods: Totally, 62 parturients undergoing cesarean section were randomized in a double-blind manner to receive either bilateral TAP block at the end of surgery with 20 ml of 0.25% bupivacaine or no TAP block, in addition to standard analgesic comprising 75 mg diclofenac 8 hourly and intravenous patient-controlled analgesia (PCA tramadol. Each patient was assessed at 0, 4, 8, 12, 24, 36, and 48 h after surgery by an independent observer for pain at rest and on movement using numeric rating scale of 0-10, time of 1 st demand for tramadol, total consumption of PCA tramadol, satisfaction with pain management and side effects. Results: Use of tramadol was reduced in patients given TAP block by 50% compared to patients given no block during 48 h after surgery (P < 0.001. Pain scores were lower both on rest and activity at each time point for 24 h in study group (P < 0.001, time of first analgesia was significantly longer, satisfaction was higher, and side effects were less in study group compared to control group. Conclusion: Transverse abdominis plane block was effective in providing analgesia with a substantial reduction in tramadol use during 48 h after cesarean section when used as adjunctive to standard analgesia.

    To evaluate and compare intercostal-iliac transversus abdominis plane (TAP) and oblique subcostal TAP (OSTAP) blocks for multimodal analgesia in patients receiving laparoscopic cholecystectomy. A prospective, randomized, double-blinded clinical study. Operating room, postoperative recovery area, and ward. In total, 60 laparoscopic cholecystectomy patients (43 women, 17 men, American Society of Anesthesiologists grades I-II) were enrolled from the general surgery department of our tertiary care center. The patients were assigned to 1 of the 3 groups. Group 1 received TAP blocks (n=20), group 2 received OSTAP blocks (n=20), and group 3 patients were used as controls and received patient-controlled analgesia (PCA) only (n=20). After the induction of anesthesia, blocks were performed bilaterally in study groups 1 and 2, using 20mL of lidocaine (5mg/mL). PCA with intravenous tramadol was routinely provided for all patients during the first 24hours. The intraoperative use of remifentanil, postoperative visual analog scale (VAS) scores, demand for PCA, and total analgesic consumption were recorded. The patients in the control group had greater analgesic demands and analgesic consumption than did those in groups 1 and 2. However, patients in the OSTAP group had lower VAS scores than did those in groups 1 and 3. The demand for analgesia was greater in the control group than in groups 1 and 2. Moreover, lower VAS scores were recorded in the OSTAP group than in groups 1 and 3 and were positively correlated with total PCA consumption among all patients. However, postoperative VAS scores were negatively correlated with the total intraoperative consumption of remifentanil at 24hours. TAP and OSTAP blocks improved postoperative analgesia in patients receiving laparoscopic cholecystectomy, which resulted in lower VAS scores and reduction in total analgesic consumption.

  17. Food hypersensitivity by inhalation

    Directory of Open Access Journals (Sweden)

    Bahna Sami L

    2009-02-01

    Full Text Available Abstract Though not widely recognized, food hypersensitivity by inhalation can cause major morbidity in affected individuals. The exposure is usually more obvious and often substantial in occupational environments but frequently occurs in non-occupational settings, such as homes, schools, restaurants, grocery stores, and commercial flights. The exposure can be trivial, as in mere smelling or being in the vicinity of the food. The clinical manifestations can vary from a benign respiratory or cutaneous reaction to a systemic one that can be life-threatening. In addition to strict avoidance, such highly-sensitive subjects should carry self-injectable epinephrine and wear MedicAlert® identification. Asthma is a strong predisposing factor and should be well-controlled. It is of great significance that food inhalation can cause de novo sensitization.

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

  19. Inhalation of uranium ores

    In previous studies the biological dispositions of individual long-lived alpha members of the uranium chain ( 238 U, 234 U and 230 Th) were determined during and following repeated inhalation exposures of rats to pitchblende (26 percent U 3 O 8 ) ore. Although finely dispersed ore in secular equilibrium was inhaled, 230 Th/ 234 U radioactivity ratios in the lungs rose from 1.0 to 2.5 during 8 weeks of exposures and increased to 9.2 by four months after cessation of exposures. Marked non-equilibrium levels were also found in the tracheobronchial lymph nodes, kidneys, liver, and femur. Daily exposures of beagle dogs to high levels of this ore for 8 days resulted in lung 230 Th/ 234 U ratios of >2.0. Daily exposures of dogs to lower levels (0.1 mg/1) for 6 months, with sacrifice 15 months later, resulted in lung and thoracic lymph node 230 Th/ 234 U ratios ranging from 3.6 to 9 and nearly 7, respectively. The lungs of hamsters exposed to carnotite (4 percent U 3 O 8 ) ore in current lifespan studies show 230 Th/ 234 U ratios as high as 2.0 during daily inhalation of this ore in secular equilibrium. Beagle dogs sacrificed after several years of daily inhalations of the same carnotite ore plus radon daughters also showed marked non-equilibrium ratios of 230 Th/ 234 U, ranging from 5.6 to 7.4 in lungs and 6.2 to 9.1 in thoracic lymph nodes. This pattern of higher retention of 230 Th than 234 U in lungs, thoracic lymph nodes, and other tissues is thus consistent for two types of uranium ore among several species and suggests a reevaluation of maximum permissible air concentrations of ore, currently based only on uranium content

The perception of the following stimuli was assessed......: feather light touch, pinprick, sharp/dull discrimination, warm, cold, point location, brush stroke direction, 2-point discrimination and pain perception. Gustation was tested for recognition of sweet, salt, sour and bitter. Mandibular block analgesia causes lingual nerve injury more frequently than...... inferior alveolar nerve injury. All grades of loss of neurosensory and gustatory functions were found, and a range of persisting neurogenic malfunctions was reported. Subjective complaints and neurosensory function tests indicate that lingual nerve lesions are more incapacitating than inferior alveolar...

Br J Anaesth 1994......;72:375-8). Many initial improvements simply involved the administration of opioid analgesics in new ways, such as continuous or on demand intravenous (i.v.) or epidural infusion. These methods allow lower total opioid dosages, provide a more stable concentration of opioid at the receptor and correspondingly...

    Full Text Available Intrathecal analgesia is an interventional form of pain relief with definite advantages and multiple complications. Administration of intrathecal analgesia needs a good resource setting and expertise. Early complications of intrathecal analgesia can be very distressing and managing these complications will need a high degree of knowledge, technical expertise and level of experience. Pain control alone cannot be the marker of quality in palliative care. A holistic approach may need to be employed that is more person and family oriented.

    The placebo effect is a neurobiological and psychophysiological process known to influence perceived pain relief. Optimization of placebo analgesia may contribute to the clinical efficacy and effectiveness of medication for acute and chronic pain management. We know that the placebo effect operates through two main mechanisms, expectations and learning, which is also influenced by sleep. Moreover, a recent study suggested that rapid eye movement (REM) sleep is associated with modulation of expectation-mediated placebo analgesia. We examined placebo analgesia following pharmacological REM sleep deprivation and we tested the hypothesis that relief expectations and placebo analgesia would be improved by experimental REM sleep deprivation in healthy volunteers. Following an adaptive night in a sleep laboratory, 26 healthy volunteers underwent classical experimental placebo analgesic conditioning in the evening combined with pharmacological REM sleep deprivation (clonidine: 13 volunteers or inert control pill: 13 volunteers). Medication was administered in a double-blind manner at bedtime, and placebo analgesia was tested in the morning. Results revealed that 1) placebo analgesia improved with REM sleep deprivation; 2) pain relief expectations did not differ between REM sleep deprivation and control groups; and 3) REM sleep moderated the relationship between pain relief expectations and placebo analgesia. These results support the putative role of REM sleep in modulating placebo analgesia. The mechanisms involved in these improvements in placebo analgesia and pain relief following selective REM sleep deprivation should be further investigated.

    Full Text Available Perioperative infusion of adenosine has been suggested to reduce the requirement for inhalation anesthetics, without causing serious adverse effects in humans. We conducted a meta-analysis of randomized controlled trials evaluating the effect of adenosine on postoperative analgesia.We retrieved articles in computerized searches of Scopus, Web of Science, PubMed, EMBASE, and Cochrane Library databases, up to July 2016. We used adenosine, postoperative analgesia, and postoperative pain(s as key words, with humans, RCT, and CCT as filters. Data of eligible studies were extracted, which included pain scores, cumulative opioid consumption, adverse reactions, and vital signs. Overall incidence rates, relative risk (RR, and 95% confidence intervals (CI were calculated employing fixed-effects or random-effects models, depending on the heterogeneity of the included trials.In total, 757 patients from 9 studies were included. The overall effect of adenosine on postoperative VAS/VRS scores and postoperative opioid consumption was not significantly different from that of controls (P >0.1. The occurrence of PONV and pruritus was not statistically significantly different between an adenosine and nonremifentanil subgroup (P >0.1, but the rate of PONV occurrence was greater in the remifentanil subgroup (P 0.1.Adenosine has no analgesic effect or prophylactic effect against PONV, but reduce systolic blood pressure and heart rates. Adenosine may benefit patients with hypertension, ischemic heart disease, and tachyarrhythmia, thereby improving cardiac function.

    Full Text Available Following the introduction of epidural for labor analgesia, debate has centered on the issue of its effect on outcome of labor; in terms of length of labor and increase in the rate of instrumental vaginal delivery and cesarean section (CS. There is no ideal study on the effect of epidural analgesia (EA on the outcome of labor due to logistic problems in randomization, blinding and getting a control group; as a result these queries are partly answered. Despite these problems, it has been established that labor epidural has minimal effect on progress of established labor and maternal request should be a sufficient indication to start an epidural. Although instrumental vaginal delivery is probably increased with epidural but obstetrician practice, pain free patient and teaching opportunity are likely factors increasing the incidence. Maternal-fetal factors and obstetric management and not the use of EA are the most important determinants of the CS rate. The purpose of this review is to summarize data from controlled trials addressing the question of whether neuraxial labor analgesia causes an increased risk of CS or rate of instrumental delivery. In addition, the review discusses whether the timing of initiation of analgesia infl uences the mode of delivery.

    Inhale, in colaboration with Pfizer and Aventis Pharma (formerly Hoechst Marion Roussel; HMR), is developing an insulin formulation utilizing its pulmonary delivery technology for macromolecules for the potential treatment of type I and II diabetes. By July 2001, the phase III program had been completed and the companies had begun to assemble data for MAA and NDA filings; however, it was already clear at this time that additional data might be required for filing. By December 2001, it had been decided that the NDA should include an increased level of controlled, long-term pulmonary safety data in diabetic patients and a major study was planned to be completed in 2002, with the NDA filed thereafter (during 2002). US-05997848 was issued to Inhale Therapeutic Systems in December 1999, and corresponds to WO-09524183, filed in February 1995. Equivalent applications have appeared to date in Australia, Brazil, Canada, China, Czech Republic, Europe, Finland, Hungary, Japan, Norway, New Zealand, Poland and South Africa. This family of applications is specific to pulmonary delivery of insulin. In February 1999, Lehman Brothers gave this inhaled insulin a 60% probability of reaching market, with a possible launch date of 2001. The analysts estimated peak sales at $3 billion in 2011. In May 2000, Aventis predicted that estimated peak sales would be in excess of $1 billion. In February 2000, Merrill Lynch expected product launch in 2002 and predicted that it would be a multibillion-dollar product. Analysts Merril Lynch predicted, in September and November 2000, that the product would be launched by 2002, with sales in that year of e75 million, rising to euro 500 million in 2004. In April 2001, Merrill Lynch predicted that filing for this drug would occur in 2001. Following the report of the potential delay in regulatory filing, issued in July 2001, Deutsche Banc Alex Brown predicted a filing would take place in the fourth quarter of 2002 and launch would take place in the first

  15. ENDOGENOUS ANALGESIA, DEPENDENCE, AND LATENT PAIN SENSITIZATION

    Taylor, Bradley K; Corder, Gregory

    2015-01-01

    Endogenous activation of μ-opioid receptors (MORs) provides relief from acute pain. Recent studies have established that tissue inflammation produces latent pain sensitization (LS) that is masked by spinal MOR signaling for months, even after complete recovery from injury and re-establishment of normal pain thresholds. Disruption with MOR inverse agonists reinstates pain and precipitates cellular, somatic and aversive signs of physical withdrawal; this phenomenon requires N-methyl-D-aspartate receptor-mediated activation of calcium-sensitive adenylyl cyclase type 1 (AC1). In this review, we present a new conceptual model of the transition from acute to chronic pain, based on the delicate balance between LS and endogenous analgesia that develops after painful tissue injury. First, injury activates pain pathways. Second, the spinal cord establishes MOR constitutive activity (MORCA) as it attempts to control pain. Third, over time, the body becomes dependent on MORCA, which paradoxically sensitizes pain pathways. Stress or injury escalates opposing inhibitory and excitatory influences on nociceptive processing as a pathological consequence of increased endogenous opioid tone. Pain begets MORCA begets pain vulnerability in a vicious cycle. The final result is a silent insidious state characterized by the escalation of two opposing excitatory and inhibitory influences on pain transmission: LS mediated by AC1 (which maintains accelerator), and pain inhibition mediated by MORCA (which maintains the brake). This raises the prospect that opposing homeostatic interactions between MORCA analgesia and latent NMDAR–AC1-mediated pain sensitization create a lasting vulnerability to develop chronic pain. Thus, chronic pain syndromes may result from a failure in constitutive signaling of spinal MORs and a loss of endogenous analgesic control. An overarching long-term therapeutic goal of future research is to alleviate chronic pain by either: a) facilitating endogenous opioid

    Full Text Available Background: Epidural analgesia is the most effective analgesics used during childbirth but is not without its problems.In the Hospital San Juan de la Cruz of Ubeda from November 2011 we have detected 3 cases of newborn infants with signs of respiratory depression. Appeared in them: normal cardiotocographic records during childbirth, use of epidural associated with fentanyl, termination by vacuum and elevated temperature in one case.ObjectivesKnow if the neonatal adaptation to extrauterine life may be influenced by the use of epidural analgesia in childbirth. Review what role can have the rise in maternal temperature and the use of epidural fentanyl with the appearance of newborn respiratory distress.MethodsLiterature Review conducted in February of 2012 in Pubmed and the Cochrane Library, using the key words: childbirth, epidural analgesia, neonatal respiratory depression.ResultsOn the respiratory depression associated with fentanyl, a Cochrane review found indicating that newborns of mothers with an epidural, had a lower pH and were less need for administration of naloxone.On PubMed we find a review study that indicates that the respiratory depression caused by the administration of opioids via neuroaxial is rare, placing it below 1 per 1000, and a clinical case that concluded that doses of fentanyl exceeding 300 µg (approx. 5 µg/kg for 4 hours previous to childbirth, have a high risk of neonatal respiratory depression at birth.The same Cochrane review indicates that the women with epidural analgesia had increased risk of maternal fever of at least 38 ° C and a recent cohort study relates this increase in temperature with a greater likelihood of neonatal adverse events (from 37.5 ° C.ConclusionsThe studies found considered safe epidurals to the neonate and the mother, except when certain conditions are met. The literature and our clinical experience have been reports linking neonatal respiratory depression with increasing temperature (37

    Women receiving an epidural for labor analgesia are at increased risk for intrapartum fever. This relationship has been supported by observational, before and after, and randomized controlled trials. The etiology is not well understood but is likely a result of noninfectious inflammation as studies have found women with fever have higher levels of inflammatory markers. Maternal pyrexia may change obstetric management and women are more likely to receive antibiotics or undergo cesarean delivery. Maternal pyrexia is associated with adverse neonatal outcomes. With these consequences, understanding and preventing maternal fever is imperative.

    Objective To compare analgesia provided by carprofen or tramadol in dogs after enucleation. Design Randomized, masked trial Animals Forty-three dogs Procedures Client-owned dogs admitted for routine enucleation were randomly assigned to receive either carprofen or tramadol orally 2 hours prior to surgery and 12 hours after the first dose. Dogs were scored for pain at baseline, and postoperatively at 0.25, 0.5, 1, 2, 4, 6, 8, 24, and 30 hours after extubation. Dogs received identical premedication and inhalation anesthesia regimens, including premedication with hydromorphone. If the total pain score was ≥9, if there was a score ≥ 3 in any one category, or if the visual analog scale score (VAS) was ≥35 combined with a palpation score of >0, rescue analgesia (hydromorphone) was administered and treatment failure was recorded. Characteristics between groups were compared with a Student’s t-test and Fisher’s exact test. The incidence of rescue was compared between groups using a log rank test. Pain scores and VAS scores between groups were compared using repeated measures ANOVA. Results There was no difference in age (p=0.493), gender (p=0.366) or baseline pain scores (p=0.288) between groups. Significantly more dogs receiving tramadol required rescue analgesia (6/21) compared to dogs receiving carprofen (1/22; p=0.035). Pain and VAS scores decreased linearly over time (p=0.038, ppain (p=0.915) or VAS scores (p=0.372) between groups at any time point (dogs were excluded from analysis after rescue). Conclusions and Clinical Relevance This study suggests that carprofen, with opioid premedication, provides more effective post-operative analgesia than tramadol in dogs undergoing enucleation.

    Full Text Available Acupuncture, as a healing art in traditional Chinese medicine, has been widely used to treat various diseases. In the history of acupuncture anesthesia, in the past decades, mechanisms of acupuncture analgesia has been widely investigated, and in recent years, acupuncture protection on organ functions has attracted great interest. This review summarized the research progress on mechanisms of acupuncture for analgesia and its protection against organ function injury in anesthesia, and its perspective of analgesia, immunomodulation, neuroendocrine regulation and multiple organ protection. The current evidence supports that acupuncture analgesia and its organ protection in anesthesia is associated with the integration of neuroendocrine-immune networks in the level of neurotransmitters, cytokines, hormones, neuronal ensembles, lymphocytes, and endocrine cells. Although the mechanisms of acupuncture analgesia and its organ protection are still not completely understood, basic as well as clinic researches on the mechanisms and applications of acupuncture and related techniques are being carried out.

    2012-02-29

    Epidural analgesia has become increasingly popular as a form of labour analgesia in Ireland. However obtaining true inform consent has always been difficult. Our study recruited 100 parturients who had undergone epidural analgesia for labour, aimed to determine the information they received prior to regional analgesia, and to ascertain their preferences regarding informed consent. Only 65 (65%) of patients planned to have an epidural. Knowledge of potential complications was variable and inaccurate, with less than 30 (30%) of women aware of the most common complications. Most women 79 (79%) believed that discomfort during labour affected their ability to provide informed consent, and believe consent should be taken prior to onset of labour (96, 96%). The results of this study helps define the standards of consent Irish patients expect for epidural analgesia during labour.

    The language structures used by antenatal educators have not been previously researched in the context of antenatal childbirth classes. Epidural analgesia for labour is a common, and a frequently asked about, component of antenatal education for parents in hospitals providing maternity care. We aimed to identify the way information is described and presented by childbirth educators to assess content and determine which language structures such as metaphor, suggestion, information and storytelling are utilized. This observational study of antenatal education was conducted at a single tertiary referral center for maternity care in Western Sydney, Australia. All three childbirth educators agreed to be video recorded whilst providing information to parents during antenatal classes. Audio data was subsequently transcribed and then analysed by two researchers, independently categorising the various language structures and types of information provided. For the purposes of the current study, data concerning a single topic was used for the analysis-'epidural analgesia for labour'. Language structures used were highly variable between educators, as was the content and time taken for the information being provided. Our findings represent a first attempt to identify baseline information used in the clinical setting of antenatal education in order to categories communication structures used. This study has identified areas for further improvements and consistency in the way educators provide information to parents and has important implications for future midwifery practice, education and research.

    For major laparoscopic surgery, as with open surgery, a multimodal analgesia plan can help to control postoperative pain. Placing a wound catheter intraoperatively following colon surgery could optimize the control of acute pain with less consumption of opioids and few adverse effects. We conducted a prospective, randomized, study of patients scheduled to undergo laparoscopic colon surgery for cancer in Galdakao-Usansolo Hospital from January 2012 to January 2013. Patients were recruited and randomly allocated to wound catheter placement plus standard postoperative analgesia or standard postoperative analgesia alone. A physician from the acute pain management unit monitored all patients for pain at multiple points over the first 48 hours after surgery. The primary outcome variables were verbal numeric pain scale scores and amount of intravenous morphine used via patient controlled infusion. 92 patients were included in the study, 43 had a wound catheter implanted and 49 did not. Statistically significant differences in morphine consumption were observed between groups throughout the course of the treatment period. The mean total morphine consumption at the end of the study was 5.63±5.02mg among wound catheter patients and 21. 86±17.88mg among control patients (P=.0001). Wound catheter patients had lower pain scale scores than control patients throughout the observation period. No adverse effects associated with the wound catheter technique were observed. The wound catheter group showed lower hospital stays with statistically significant difference (P=.02). In patients undergoing laparoscopic colon surgery, continuous infusion of local anaesthetics through interfascial wound catheters during the first 48h aftersurgery reduced the level of perceived pain and also reduced parenteral morphine consumption with no associated adverse effects and lower hospital stays.

    To discover evidence for defining the registered nurse's (RN's) role in the management of epidural analgesia in the labor and delivery setting. The Labor Epidural Nurse Safety (LENS) study consisted of two parts. The first part was a 10-year retrospective review of the outcomes of 2,568 laboring women for whom epidural catheters had been placed and verified by an anesthesiologist or certified registered nurse anesthetist, then continuous epidural infusion initiated, and basal rate or patient-controlled epidural analgesia (PCEA) dose increased, if needed, within specified parameters by specially trained labor and delivery RNs. The second part compared the outcomes of the neonates born to the 2,568 women in the first part of the study with neonates born to mothers who received PCEA with a continuous infusion initiated and managed exclusively by anesthesiologists and/or certified registered nurse anesthetists at two control sites. Maternal outcomes were quantified by incidences of clinically significant hypotension and sentinel events, such as respiratory distress, cardio/respiratory distress, loss of consciousness, and seizures. Evidence of neonatal outcomes was collected by comparing Apgar scores. No sentinel events occurred, and there was no increase in maternal hypotensive events in the RN-managed group. There were no statistically significant differences in Apgar scores between the experimental and control groups. Specially trained RNs can safely initiate continuous infusions and increase the basal rate of epidural analgesia infusions or PCEA doses administered to laboring women, after insertion and confirmation of correct catheter placement by a qualified anesthesia provider, without adversely affecting maternal and fetal/neonatal outcomes.

    To evaluate the daily practice of postoperative PCA in Nancy University Hospital, in continuity with a quality program of postoperative pain (POP) care conducted in 2003. A retrospective audit of patient medical records. A review of all the medical records of consecutive surgical patients managed by PCA over a 5-week period in six surgical services. Criteria studied: Evaluation of hospital means (eight criteria) and of medical and nursing staff practice (16 criteria). A second audit was conducted 6 months after the implementation of quality improvement measures. Assessment of the hospital means: temperature chart including pain scores and PCA drug consumption, patient information leaflet, PCA protocol, postoperative pre-filled prescription form (PFPF) for post-anaesthesia care including PCA, and optional training of nurses in postoperative pain management. EVALUATION OF PRACTICES: One hundred and fifty-nine files of a total of 176 patients were analyzed (88%). Improvements noted after 6 months: trace of POP evaluation progressed from 73 to 87%, advance prescription of PCA adjustment increased from 56 to 68% and of the treatment of adverse effects from 54 to 68%, trace of PCA adaptation by attending nurse from 15 to 43%, trace of the administration of the treatment of adverse effects by attending nurse from 24% to 64%, as did the use of PFPF from 59 to 70%. The usefulness of a pre-filled prescription form for post-anaesthesia care including PCA prescription is demonstrated.

    We have hypothesized that etoricoxib premedication would reduce the need for additional opioids following orthopedic trauma surgery. A double blind, controlled study, conducted in King Fahd University Hospital, King Faisal University, Dammam, Kingdom of Saudi Arabia. After obtaining the approval of Research and Ethics Committee and written consent, 200 American Society of Anesthesiology grade I and II patients that underwent elective upper limb or lower limb fracture fixation surgeries during the period from August 2005 to October 2007 were studied. Patients were randomly premedicated using 120 mg of etoricoxib or placebo n=100, each. To alleviate postoperative pain, a patient controlled analgesia device was programmed to deliver one mg of morphine intravenously locked lockout time, 6 minutes. Visual analog scale and total postoperative morphine consumption over 24 hours and the adverse effects were recorded. One hundred patients in each group completed the study period. Etoricoxib premedication provides a statistically significant postoperative morphine sparing effect over 24 hours postoperatively. Total morphine consumption was 44.2 (8.2) in the placebo and 35.17 mg in the etoricoxib groups p<0.001. The incidence of nausea and vomiting requiring treatment was lower in the etoricoxib group. p=0.014. The postoperative blood loss was similar in both groups. Etoricoxib is a suitable premedication before traumatic orthopedic surgery as it enhanced postoperative analgesia and reduced the need for morphine. (author)

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

    Despite epidural analgesia increasingly being utilized in hospitals, very little research-based evidence is available about registered nurses' (RNs) and midwives' knowledge of this technique. To describe the current epidural knowledge levels of RNs and midwives in a multi-site setting. RNs and midwives at four, regional teaching facilities completed an epidural knowledge test. The instrument included demographic items and five knowledge subscales relating to epidural analgesia: spinal cord anatomy and physiology; epidural pharmacology; complications of epidural analgesia; assessment of sensory and motor blockade and the general management of patients with epidural analgesia. A total of 408 (99.7% response) RNs and midwives completed the test. Respondents demonstrated good knowledge of sensory and motor blockade assessment and the general management of epidural analgesia subscales with correct responses to 75 and 77% of the questions in these subscales, respectively. Fair knowledge relating to the spinal cord anatomy and physiology subscale was demonstrated with 69% of the questions answered correctly. The knowledge subscales relating to epidural pharmacology (57% correct responses) and the complications of epidural analgesia (56% correct responses) were problematic for the sample. The research results provide generalizable information about what RNs and midwives know about epidural analgesia. These results are an important guide in the development of new and existing dedicated epidural education programs. The results also provide some direction for further research into this important topic.

  14. Labour analgesia and the baby: good news is no news.

    When investigating different methods of maternal pain relief in labour, neonatal outcome has not always been at the forefront, or else maternal changes, such as haemodynamics, fever, length of labour, need for oxytocin or type of delivery, are taken as surrogates for neonatal outcome. It is essential to examine the actual baby and to appreciate that labour pain itself has adverse consequences for the baby. For systemic analgesia, pethidine has been most extensively studied and compared with neuraxial analgesia. It depresses fetal muscular activity, aortic blood flow, short-term heart rate variability and oxygen saturation. In the newborn it exacerbates acidosis, depresses Apgar scores, respiration, neurobehavioural score, muscle tone and suckling. Alternatives have few advantages, remifentanil being the most promising. Neuraxial analgesia is associated with better Apgar scores and variable neurobehavioural changes. Neonatal acid-base status is not only better with epidural than with systemic opioid analgesia, it is also better than with no analgesia. The effect on breast feeding has yet to be established, though it is certainly no worse than that of systemic opioid analgesia. Variations in neuraxial technique have little impact on the newborn. Widespread ignorance of the benefit to the newborn of neuraxial labour analgesia in the UK among non-anaesthetists needs to be combated. Copyright © 2010 Elsevier Ltd. All rights reserved.

    [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 Direct delivery of medication to the target organ results in a high ratio of local to systemic bioavailability and has made aerosol delivery of respiratory medication the route of choice for the treatment of obstructive lung diseases. The most commonly prescribed device is the pressurized metered dose inhaler (pMDI; its major drawback is the requirement that inspiration and actuation of the device be well coordinated. Other requirements for effective drug delivery include an optimal inspiratory flow, a full inspiration from functional residual capacity and a breath hold of at least 6 s. Available pMDIs are to be gradually phased out due to their use of atmospheric ozone-depleting chlorofluorocarbons (CFCs as propellants. Newer pMDI devices using non-CFC propellants are available; preliminary experience suggests these devices greatly increase systemic bioavailability of inhaled corticosteroids. The newer multidose dry powder inhalation devices (DPIs are breath actuated, thus facilitating coordination with inspiration, and contain fewer ingredients. Furthermore, drug delivery is adequate even at low inspired flows, making their use appropriate in almost all situations. Equivalence of dosing among different devices for inhaled corticosteroids will remain imprecise, requiring the physician to adjust the dose of medication to the lowest dose that provides adequate control of asthma. Asthma education will be needed to instruct patients on the effective use of the numerous inhalation devices available.

    2012-01-01

    Full Text Available Background: Paravertebral block is a popular regional anesthetic technique used for perioperative analgesia in multiple surgical procedures. There are very few randomized trials of its use in laparoscopic cholecystectomy in medical literature. This study was aimed at assessing its efficacy and opioid-sparing potential in this surgery. Methods: Fifty patients were included in this prospective randomized study and allocated to two groups: Group A (25 patients receiving general anesthesia alone and Group B (25 patients receiving nerve-stimulator-guided bilateral thoracic Paravertebral Block (PVB at T6 level with 0.3 ml/kg of 0.25% bupivacaine prior to induction of general anesthesia. Intraoperative analgesia was supplemented with fentanyl (0.5 μg/kg based on hemodynamic and clinical parameters. Postoperatively, patients in both the groups received Patient-Controlled Analgesia (PCA morphine for the first 24 hours. The efficacy of PVB was assessed by comparing intraoperative fentanyl requirements, postoperative VAS scores at rest, and on coughing and PCA morphine consumption between the two groups. Results: Intraoperative supplemental fentanyl was significantly less in Group B compared to Group A (17.6 μg and 38.6 μg, respectively, P =0.001. PCA morphine requirement was significantly low in the PVB group at 2, 6, 12, and 24 hours postoperatively compared to that in Group A (4.4 mg vs 6.9 mg, 7.6 mg vs 14.2 mg, 11.6 mg vs 20.0 mg, 16.8 mg vs 27.2 mg, respectively; P <0.0001 at all intervals. Conclusion: Pre-induction PVB resulted in improved analgesia for 24 hours following laparoscopic cholecystectomy in this study, along with a significant reduction in perioperative opioid consumption and opioid-related side effects.

    Full Text Available Background: Satisfactory analgesia is of great importance in the labor. The clinical efficacy and side effects of remifentanil in the management of labor pain had been evaluated. Dexmedetomidine (DMET demonstrates an antinociceptive effect in visceral pain conditions. Aims of the study were to assess whether the combination of DMET with remifentanil would produce a synergistic effect that results in lower analgesic requirements. Furthermore, whether this combination would have less maternal and neonatal adverse effects. Patients and Methods: Sixty American Society of Anesthesiologists physical status I-II pregnant women had been enrolled into this study. All were full term (37-40 weeks′ gestation, singleton fetus with cephalic presentation in the first stage of spontaneous labor. They were divided into two groups group (I Patient-controlled IV remifentanil analgesia (bolus dose 0.25 μg/kg, lockout interval 2 min increased by 0.25 μg/kg to a maximum bolus dose 1 μg/kg in addition to a loading dose of DMET 1 μg/kg over 20 min, followed by infusion at 0.5 μg/kg/h group (II Patient-controlled IV remifentanil analgesia (PCA (bolus dose 0.25 μg/kg, lockout interval 2 min increased by 0.25 μg/kg to a maximum bolus dose 1 μg/kg in addition to a the same volume of normal saline as a loading dose, followed by a continuous saline infusion. Visual analog scale score, maternal, and fetal complications and patients′ satisfaction were recorded. Results: Patients receiving a combination of PCA remifentanil and DMET had a lower pain score compared with remifentanil alone in the second stage of labor (P = 0.001. The Total consumption of remifentanil was reduced by 53.3% in group I. There was an increased incidence of maternal complications and a lower patient satisfaction score in group II. Conclusion: DMET has an opioid sparing effect; a combination of DMET and remifentanil produces a synergistic effect that results in lower analgesic requirements

    Postoperative analgesia is important because it prevents the adverse effects of pain. To study the effect of preoperative or intraoperative application of dexketoprofen on postoperative analgesia and patient comfort in patients undergoing septorhinoplasty. A randomized, double-blind, placebo-controlled study. The study included 100 patients randomly assigned to four groups. Patients from group 50/0 got 50 mg dexketoprofen 30 minutes prior to the operation; patients from group 0/50 got 50 mg dexketoprofen 30 minutes after the operation, and patients from group 25/25 got 25 mg dexketoprofen both 30 minutes prior and 30 minutes after the operation. Dexketoprofen was not applied to any of the patients from group C. Once in the recovery room, patient-controlled analgesia was received to all patients. The patients' visual analog scale (VAS), sedation, nausea and vomiting and dyspepsia complaints were recorded at 1, 2, 3, 4, 5, 6, 7, 8, 12 and 24 hours. In addition, patient satisfaction, intraoperative fentanyl and consumption of tramadol in the postoperative 24 hour period were recorded. The VAS, nausea and vomiting, sedation and patient satisfaction scores were lower in patients from all groups that had received dexketoprofen compared to the controls. There was no difference in intraoperative fentanyl consumption between the groups. The consumption of tramadol was significantly higher in group C compared to all other groups. Dexketoprofen provides good postoperative analgesia and patient satisfaction if applied intravenously to septorhinoplasty patients. However, there is no significant difference between preoperative and intraoperative applications of dexketoprofen.

    For men the worst aspect of childbirth is witnessing their partner in pain. The aim of this study was to investigate fathers' attitudes towards labor and delivery with and without epidural analgesia. The study was performed using a questionnaire that included yes/no, multiple choice or 6-point ordinal scale answers. Expectant fathers whose partners were nullipara between 36 and 38 weeks of gestation were recruited and the questionnaires were administered on the day after the birth. To investigate paternal anxiety during labor, the State part of the State-Trait Anxiety Inventory was used. The questionnaire was completed by 243 fathers. Sixty percent (145) of the parturients received epidural analgesia and 40% (98) did not. Paternal characteristics were comparable. Fathers whose partners did not receive epidural analgesia felt their presence as troublesome and unnecessary (Pinvolvement (Pfathers whose partners did not or did receive epidural analgesia (Pinvolvement, participation and satisfaction with the experience of childbirth.

    The terms 'analgesia' and 'anaesthesia' have been defined by emphasizing differing aspects of their effects. The distinction between these interventions has not been clarified by their definitions. The historical remedies for pain were similarly unclear. This lack of clarity is apparent in the introduction of chloroform in childbirth, which has much in common with the introduction and effects of epidural analgesia. The reasons for and benefits of this lack of clarity are examined.

    Electroacupuncture analgesia was used for surgery in horses and donkeys. A KWD-808 electrical stimulator was used to incrementally induce a dense, dispersed wave output at frequencies from 20 to 55 Hz, which was maintained at a frequency of 55 Hz, and to change the amplitude of the wave to the best grading number for the suggested operation in each animal. Induction of analgesia lasted for 20-30 minutes, and the effect of analgesia was maintained for 20-45 minutes depending on the type of surgery performed. The exhibited clinical signs, physical examination data, and the responses of all animals were used for evaluating the periods of analgesia. Although the majority of the cases (95%) had no response to strong surgical pain, they experienced significant increases in heart rates and respiratory rates during induction. The lack of pain, relaxed surgical procedures, reduced intraoperative bleeding, and improved healing without complications were all definite benefits of using electroacupuncture analgesia in surgery. Thus, this study has provided surgical evidence supporting the effectiveness of electroacupuncture analgesia, as well as confirming its reliability, in the field of equine anesthesia and surgery.

    To verify the feasibility of electroacupuncture analgesia applied to gynecologic outpatient operation. Two hundred patients were randomly divided into an electroacupuncture analgesia group and an intravenous anesthesia group, 100 cases in each group. Operation types included artificial abortion, diagnostic curettage and remove of intrauterine divice. The electroacupuncture analgesia group was treated with electroacupuncture at bilateral Hegu (LI 4) and Neiguan (PC 6), and the routine gynecologic outpatient operation was performed under patients' waking state. The intravenous anesthesia group was treated with routine gynecologic outpatient operation after intravenous injection of fentanyl and propofol. The excellent rate and the effective rate of analgesia were 88.0% (88/100) and 100.0% (100/100) in the electroacupuncture analgesia group, and 94.0% (94/100) and 100.0% (100/100) in the intravenous anesthesia group, with no statistically significant differences between the two groups (all P > 0.05). There was no adverse reaction in the electroacupuncture anesthesia group, but 11 cases of adverse reactions in the intravenous anesthesia group. Electroacupuncture analgesia can effectively alleviate the pain during gynecologic outpatient operation and it is simple and safe without adverse reactions.

    Full Text Available Background. The study presents the experience with epidural analgesia (EPA for pain relief in Izola General Hospital from 2003 to 2006, the differences of labour between epidural analgesia and without it and the parturients’ satisfaction. Methods. A retrospective observational study was performed. Data were compared between 214 parturients with EPA matched by 214 parturients without. The control parturient was the equiipara with a term birth and the cephalic presentation of fetus that delivered just before the parturient of the EPA group. Maternal age, labor length, rate of oxitocin use, instrumental deliveries and cesarean sections, Apgar scores and birthweights were compared. The questionnaire was used to estimate the pain in 62 parturients. Results. In GH Izola in 214 parturients (10 % EPA was applied for labour pain relief in the period from July 2003 till December 2006. In the EPA group there was a statistically significance compared with the control group: higher parturients’ mean age (30.5 vs 28.7 y.o.; p < 0.0005, longer labour length (278 vs 222 min; p < 0.0005, higher oxitocin use rate (93.4 % vs 72.9 %; p < 0.0001 and higher instrumental delivery rate (vacuum extraction 14 % vs 1.9 %; p < 0.0001. The cesarean section rates were equal in both groups. Despite the higher instrumental delivery rate and the longer labour length in the EPA group there were no worse perinatal outcomes, neither was statisticaly significant difference in Apgar scores compared with the control group. The mean intensity of pain was highest before the EPA application (VAS 7, lowest during the transition stage (VAS 1.5 and some higher during the second phase (VAS 2.7. Most of parturients in the EPA group were satisfied; 92 % of them evaluated the EPA as good or very good. Conclusions. EPA is a very effective method for pain control during labor. The parturients’ satisfaction with this pain control method is appropriate. Despite the higher instrumental

    Pain is a major problem in patients after cesarean and medication such as aromatherapy which is a complementary therapy, in which the essences of the plants oils are used to reduce such undesirable conditions. In this study, the effect of aromatherapy using Lavender (Lavandula) essential oil on cesarean postoperative pain was assessed. In a triple blind, randomized placebo-controlled trial study, 60 pregnant women who were admitted to a general hospital for cesarean section, were divided randomly into two groups. After cesarean, the Lavender group inhaled about 3 drops of 10% Lavender oil essence and the placebo group inhaled 3 drops of placebo after the start of postoperative pain, four, eight and 12 hours later, for 5 minutes from the 10 cm distance. Patient's pain was measured by the VAS (Visual Analog Scale) score before and after each intervention, and vital sign, complications and level of satisfaction of every patient were recorded before and after aromatherapy. There was no statistically significant difference between groups in age, height, weight, and time to the first analgesic requirement. Patients in the Lavender group had less postoperative pain in four (P = 0.008), eight (P = 0.024) and 12 (P = 0.011) hours after first medication than the placebo group. The decreased heart rate and patients' level of satisfaction with analgesia were significantly higher in the Lavender group (P = 0.001). In the placebo group, the use of diclofenac suppositories for complete analgesia was also significantly higher than the Lavender group (P = 0.008). The inhaled Lavender essence may be used as a part of the multidisciplinary treatment of pain after cesarean section, but it is not recommended as the sole pain management.

  18. Analgesia/anesthesia for external cephalic version.

    2013-06-01

    Professional society guidelines recommend that women with breech presentation be delivered surgically due to a higher incidence of fetal risks compared with vaginal delivery. An alternative is attempted external cephalic version, which if successful, enables attempted vaginal delivery. Attitudes towards external cephalic version (ECV) will be considered in this review, along with pain relief methods and their impact on ECV success rates. Articles suggest that ECV is infrequently offered, due to both physician and patient factors. Success of ECV is higher in multiparous women, complete breech, posterior placenta, or smaller fetus. Preterm ECV performance does not increase vaginal delivery rates. Neuraxial techniques (spinal or epidural) significantly increase ECV success rates, as do moxibustion and hypnosis. Four reviews summarized studies considering ECV and neuraxial techniques. These reviews suggest that neuraxial techniques using high (surgical) doses of local anesthetic are efficacious compared with control groups not using anesthesia, whereas techniques using low-doses are not. Low-dose versus high-dose neuraxial analgesia/anesthesia has not been directly compared in a single study. Based on currently available data, the rate of cephalic presentation is not increased using neuraxial techniques, but vaginal delivery rates are higher. ECV appears to be a low-risk procedure. The logistics of routine ECV and provision of optimal neuraxial techniques for successful ECV require additional research. Safety aspects of neuraxial anesthesia for ECV require further investigation.

    Full Text Available Epidural analgesia is commonly used in large animals. It is an easy, cheap, and effective technique used to prevent or control pain during surgeries involving the tail, anus, vulva, perineum, caudal udder, scrotum, and upper hind limbs. The objectives of this article were to comprehensively review and summarize all scientific data available in the literature on new techniques and drugs or drug combinations used for epidural anesthesia in cattle, camel, and buffalo. Only articles published between 2006 and 2016 were included in the review. The most common sites for epidural administration in cattle, camels, and buffalos were the sacrococcygeal intervertebral space (S5-Co1 and first intercoccygeal intervertebral space (Co1-Co2. The most frequently used drugs and dosages were lidocaine (0.22-0.5 mg/kg, bupivacaine (0.125 mg/kg, ropivacaine (0.11 mg/kg, xylazine (0.05 mg/kg, medetomidine (15 μg/kg, romifidine (30-50 μg/kg, ketamine (0.3-2.5 mg/kg, tramadol (1 mg/kg, and neostigmine (10 μg/kg, and the clinical applications, clinical effects, recommendations, and side effects were discussed.

    The purpose of this article was to investigate the relationship between analgesia, sedation, and memory of intensive care. One hundred fifty-two adult, cooperative intensive care unit (ICU) patients were interviewed 6 months after hospital discharge about their memory of intensive care. The patient was considered to be cooperative when he/she was aware of self and environment at the interview. The patients were grouped as follows: A (45 patients) substantially no sedation, B (85) morphine, and C (22) morphine and other sedatives. The patients having no memory of intensive care were 38%, 34%, and 23% respectively, in the three groups. They were less ill, according to SAPS II (P memories was not different among the three groups. Females reported at least one emotional memory more frequently than males (odds ratio 4.17; 95% CI 10.97-1.59). The patients receiving sedatives in the ICU are not comparable with those receiving only opiates or nothing, due to the different clinical condition. The lack of memory of intensive care is present in one third of patients and is influenced more by length of stay in ICU than by the sedation received. Sedation does not influence the incidence of factual, sensation, and emotional memories of ICU admitted patients. Females have higher incidences of emotional memories than males.

    The mechanisms controlling pain in newborns during delivery are poorly understood. We explored the hypothesis that oxytocin, an essential hormone for labor and a powerful neuromodulator, exerts analgesic actions on newborns during delivery. Using a thermal tail-flick assay, we report that pain sensitivity is two-fold lower in rat pups immediately after birth than 2 days later. Oxytocin receptor antagonists strongly enhanced pain sensitivity in newborn, but not in 2-day-old rats, whereas oxytocin reduced pain at both ages suggesting an endogenous analgesia by oxytocin during delivery. Similar analgesic effects of oxytocin, measured as attenuation of pain-vocalization induced by electrical whisker pad stimulation, were also observed in decerebrated newborns. Oxytocin reduced GABA-evoked calcium responses and depolarizing GABA driving force in isolated neonatal trigeminal neurons suggesting that oxytocin effects are mediated by alterations of intracellular chloride. Unlike GABA signaling, oxytocin did not affect responses mediated by P2X3 and TRPV1 receptors. In keeping with a GABAergic mechanism, reduction of intracellular chloride by the diuretic NKCC1 chloride co-transporter antagonist bumetanide mimicked the analgesic actions of oxytocin and its effects on GABA responses in nociceptive neurons. Therefore, endogenous oxytocin exerts an analgesic action in newborn pups that involves a reduction of the depolarizing action of GABA on nociceptive neurons. Therefore, the same hormone that triggers delivery also acts as a natural pain killer revealing a novel facet of the protective actions of oxytocin in the fetus at birth. PMID:21519396

    Full Text Available Abstract Background Relative analgesia (RA, defined as the use of inhalation sedation with nitrous oxide and oxygen, is one of the most common pharmacological behavior management techniques used to provide sedation and analgesia for dental patients. This study aimed to assess RA licensed Brazilian dentists’ practices and opinions about nitrous oxide/oxygen sedation in the dental setting. Methods A cross sectional national survey was conducted with 281 dentists who were certified to perform RA, using an electronically mailed self-administered questionnaire containing closed questions about their practices and opinions regarding RA. Practice and opinion were individually analyzed by descriptive statistics. Non-parametric tests assessed the relationships between RA practice and independent variables. To test the interplay between practices and opinions, a k-means clusters analysis was used to divide the group for statistical comparisons. Results The response rate was 45.2%. Women made up 64.6% of the respondents, the mean age was 39.1 years (SD = 9.8, and the mean time since graduation in dentistry was 16 years (SD = 9.7. Seventy-seven percent of respondents reported the use of RA in clinical practice, most of them ‘sometimes’ (53.5%, and focusing more on adult patients. Patients with certain physical or mental deficiencies were indications associated with RA practice. ‘Equipment acquisition’ (p  Conclusion Most of the RA licensed Brazilian dentists interviewed currently use RA. Current practice of RA and frequency of use determined the degree of favorable opinion about this inhalation sedation among this group of respondents.

    Asthma and chronic obstructive pulmonary disease (COPD) patients are required to inhale forcefully and deeply to receive medication when using a dry powder inhaler (DPI). There is a clinical need to objectively monitor the inhalation flow profile of DPIs in order to remotely monitor patient inhalation technique. Audio-based methods have been previously employed to accurately estimate flow parameters such as the peak inspiratory flow rate of inhalations, however, these methods required multiple calibration inhalation audio recordings. In this study, an audio-based method is presented that accurately estimates inhalation flow profile using only one calibration inhalation audio recording. Twenty healthy participants were asked to perform 15 inhalations through a placebo Ellipta™ DPI at a range of inspiratory flow rates. Inhalation flow signals were recorded using a pneumotachograph spirometer while inhalation audio signals were recorded simultaneously using the Inhaler Compliance Assessment device attached to the inhaler. The acoustic (amplitude) envelope was estimated from each inhalation audio signal. Using only one recording, linear and power law regression models were employed to determine which model best described the relationship between the inhalation acoustic envelope and flow signal. Each model was then employed to estimate the flow signals of the remaining 14 inhalation audio recordings. This process repeated until each of the 15 recordings were employed to calibrate single models while testing on the remaining 14 recordings. It was observed that power law models generated the highest average flow estimation accuracy across all participants (90.89±0.9% for power law models and 76.63±2.38% for linear models). The method also generated sufficient accuracy in estimating inhalation parameters such as peak inspiratory flow rate and inspiratory capacity within the presence of noise. Estimating inhaler inhalation flow profiles using audio based methods may be

    The endogenous analgesia (EA) system is psychophysically evaluated using various paradigms, including conditioned pain modulation (CPM) and offset analgesia (OA) testing, respectively, the spatial and temporal filtering processes of noxious information. Though both paradigms assess the function of the EA system, it is still unknown whether they reflect the same aspects of EA and consequently whether they provide additive or equivalent data. Twenty-nine healthy volunteers (15 males) underwent 5 trials of different stimulation conditions in random order including: (1) the classic OA three-temperature stimulus train ('OA'); (2) a three-temperature stimulus train as control for the OA ('OAcon'); (3) a constant temperature stimulus ('constant'); (4) the classic parallel CPM ('CPM'); and (5) a combination of OA and CPM ('OA + CPM'). We found that in males, the pain reduction during the OA + CPM condition was greater than during the OA (P = 0.003) and CPM (P = 0.07) conditions. Furthermore, a correlation was found between OA and CPM (r = 0.62, P = 0.01) at the time of maximum OA effect. The additive effect found suggests that the two paradigms represent at least partially different aspects of EA. The moderate association between the CPM and OA magnitudes indicates, on the other hand, some commonality of their underlying mechanisms.

    PURPOSE: This two-part review summarizes the current knowledge of physiological mechanisms, pharmacological modalities and controversial issues surrounding preemptive analgesia. SOURCE: Articles from 1966 to present were obtained from the MEDLINE databases. Search terms included: analgesia, preemptive; neurotransmitters; pain, postoperative; hyperalgesia; sensitization, central nervous system; pathways, nociception; anesthetic techniques; analgesics, agents. Principal findings: The physiological basis of preemptive analgesia is complex and involves modification of the pain pathways. The pharmacological modalities available may modify the physiological responses at various levels. Effective preemptive analgesic techniques require multi-modal interception of nociceptive input, increasing threshold for nociception, and blocking or decreasing nociceptor receptor activation. Although the literature is controversial regarding the effectiveness of preemptive analgesia, some general recommendations can be helpful in guiding clinical care. Regional anesthesia induced prior to surgical trauma and continued well into the postoperative period is effective in attenuating peripheral and central sensitization. Pharmacologic agents such as NSAIDs (non-steroidal anti-inflammatory drugs) opioids, and NMDA (N-methyl-D-aspartate) - and alpha-2-receptor antagonists, especially when used in combination, act synergistically to decrease postoperative pain. CONCLUSION: The variable patient characteristics and timing of preemptive analgesia in relation to surgical noxious input requires individualization of the technique(s) chosen. Multi-modal analgesic techniques appear most effective.

    PURPOSE: This two-part review summarizes the current knowledge of physiological mechanisms, pharmacological modalities and controversial issues surrounding preemptive analgesia. SOURCE: Articles from 1966 to present were obtained from the MEDLINE databases. Search terms included analgesia, preemptive; neurotransmitters; pain, postoperative; hyperalgesia; sensitization, central nervous system; pathways, nociception; anesthetic techniques; analgesics, agents. Principal findings: In Part I of this review article, techniques and agents that attenuate or prevent central and peripheral sensitization were reviewed. In Part II, the conditions required for effective preemptive techniques are evaluated. Specifically, preemptive analgesia may be defined as an antinociceptive treatment that prevents establishment of altered central processing of afferent input from sites of injury. The most important conditions for establishment of effective preemptive analgesia are the establishment of an effective level of antinociception before injury, and the continuation of this effective analgesic level well into the post-injury period to prevent central sensitization during the inflammatory phase. Although single-agent therapy may attenuate the central nociceptive processing, multi-modal therapy is more effective, and may be associated with fewer side effects compared with the high-dose, single-agent therapy. CONCLUSION: The variable patient characteristics and timing of preemptive analgesia in relation to surgical noxious input require individualization of the technique(s) chosen. Multi-modal analgesic techniques appear more effective.

    Full Text Available Objectives We hypothesized that preoperative (pre-op ultrasound (US-guided posterior transversus abdominis plane block (TAP and US-guided ilioinguinal and iliohypogastric nerve block (ILI+IHG will produce a comparable analgesia after Lichtenstein patch tension-free method of open inguinal hernia repair in adult men. The genital branch of the genitofemoral nerve will be blocked separately. Methods This is a prospective, randomized, controlled, and observer-blinded clinical study. A total of 166 adult men were randomly assigned to one of three groups: a pre-op TAP group, a pre-op ILI+IHG group, and a control group. An intraoperative block of the genital branch of the genitofemoral nerve was performed in all patients in all three groups, followed by postoperative patient-controlled intravenous analgesia with morphine. The pain intensity and morphine consumption immediately after surgery and during the 24 hours after surgery were compared between the groups. Results A total of 149 patients completed the study protocol. The intensity of pain immediately after surgery and morphine consumption were similar in the two “block” groups; however, they were significantly decreased compared with the control group. During the 24 hours after surgery, morphine consumption in the ILI+IHG group decreased compared with the TAP group, as well as in each “block” group versus the control group. Twenty-four hours after surgery, all evaluated parameters were similar. Conclusion Ultrasound-guided ILI+IHG provided better pain control than US-guided posterior TAP following the Lichtenstein patch tension-free method of open inguinal hernia repair in men during 24 hours after surgery.

Although patient-controlled devices are frequently used in patients ≥6 years of age, alternative modes of analgesic delivery are needed in infants.Objective: To examine the safety and efficacy of nurse-controlled analgesia (NCA in neonates less than 1 year of age.Methods: Data from patients <1 year of age receiving NCA as ordered by the Acute Pain Service at our institution were collected over a 5-year period and reviewed retrospectively. The primary outcomes were activation of the institution’s Rapid Response Team (RRT or Code Blue, signifying severe adverse events. Pain score after NCA initiation was a secondary outcome.Results: Among 338 girls and 431 boys, the most common opioid used for NCA was fentanyl, followed by morphine and hydromorphone. There were 39 (5% cases involving RRT or Code Blue activation, of which only one (Code Blue was activated due to a complication of NCA (apnea. Multivariable logistic regression demonstrated morphine NCA to be associated with greater odds of RRT activation (OR=3.29, 95% CI=1.35, 8.03, P=0.009 compared to fentanyl NCA. There were no statistically significant differences in pain scores after NCA initiation across NCA agents.Conclusion: NCA is safe in neonates and infants, with comparable efficacy demonstrated for the three agents used. The elevated incidence of RRT activation in patients receiving morphine suggests caution in its use and consideration of alternative agents in this population.

    The aim of the study was to assess 100 preschool children's satisfaction grading of relative analgesia (RA) after completing dental treatment by collecting their opinion on this technique through a verbal questionnaire. After completing dental care a simple verbal questionnaire (3 questions) was administered by the operator. The questionnaire investigated: 1) patient's satisfaction about the sedation treatment; 2) patient's agreement to re-experiment the technique and 3) patient's emotions while sedated. Moreover, following treatment, each child was invited to make a drawing on the experience. Data obtained were classified in 3 groups: group 1 (87% of children) appreciated RA and would agree to repeat the experience; group 2 (4% of the sample) did not answer the verbal questionnaire and group 3 (9%) did not enjoy the sedation technique. Only 15 children completed a drawing; conducting a psychological analysis through C.R. Rogers' theory of Person Centred Approach coupled with the handwriting analysis methodology defined by Girolamo Moretti, positive features were found in the majority of the drawings (13 out of 15). The majority (87%) of the sample appreciated to experience nitrous oxide inhalation sedation and would undergo a further appointment under RA.

    Six volunteers each smoked simultaneously, in a small unventilated room (volume 27 950 liter), a cannabis cigarette containing 17.1 mg delta 9-tetrahydrocannabinol (THC). A further four subjects - passive inhalers - remained in the room during smoking and afterwards for a total of 3 h. Blood and urine samples were taken from all ten subjects and analyzed by radioimmunoassay for THC metabolites. The blood samples from the passive subjects taken up to 3 h after the start of exposure to cannabis smoke showed a complete absence of cannabinoids. In contrast, their urine samples taken up to 6 h after exposure showed significant concentrations of cannabinoid metabolites (less than or equal to 6.8 ng ml-1). These data, taken with the results of other workers, show passive inhalation of cannabis smoke to be possible. These results have important implications for forensic toxicologists who are frequently called upon to interpret cannabinoid levels in body fluids.

    Full Text Available Preemptive analgesia, initiated before the surgical procedure to prevent pain in the early postoperative period has the potential to be more effective than a similar analgesic treatment initiated after surgery. This article aims to review all the recent published evidences that assess the efficacy of this enigmatic concept. Materials and Methods: We reviewed original research articles, case-reports, meta-analyses, randomized control trials (RCTs, and reviews based on pain physiology for preemptive analgesia from Medline, Medscape, and PubMed from 1993 to 2013. A broad free-text search in English was undertaken with major keywords "Preemptive analgesia," "postoperative pain," "preoperative," and "preincisional". Results: Review of publications showed that intravenous (IV nonsteroidal anti-inflammatory drugs (NSAIDs are quite effective when used alone, as well as with low dose iv ketamine, preemptively to provide adequate postoperative analgesia. However, ketamine has a doubtful role as a standalone agent. Preemptive administration of LA at the incision site reduces postoperative pain, but achieves an analgesic effect similar to that of postincisional anesthetic infiltration as does intraperitoneal administration. Preemptive epidural analgesia has proved its efficacy in controlling perioperative immune function and pain in comparison to parenteral opioids. Gamma-amino butyric acid (GABA analogues like gabapentin and pregabalin have great potential as preemptive analgesic with the added advantage of its anxiolytic effect. Conclusion: Multimodal approaches that address multiple sites along the pain pathway is necessary to treat pain adequately. However, we need to find an answer to the question of how to obtain the maximal clinical benefits with the use of preemptive analgesia.

    The measurement of the body's capacity to compensate for reduced blood volume can be assessed with a compensatory reserve measurement (CRM). The CRM, which is calculated from changes in features of the arterial waveform, represents the integration of compensatory mechanisms during states of low tissue perfusion and oxygenation, such as hemorrhage. This study was designed to test the hypothesis that pain which activates compensatory mechanisms and analgesia that result in reduced blood pressure are associated with lower compensatory reserve. This study evaluated CRM in obstetric patients during labor as pain intensity increased from no pain to severe pain and compared CRM before and after epidural anesthesia. CRM was calculated from a finger pulse oximeter placed on the patient's index finger and connected to the DataOx monitor in healthy pregnant women (n = 20) before and during the active labor phase of childbirth. As pain intensity, based on an 11-point scale (0, no pain; 10, worst pain), increased from 0 to 8.4 ± 0.9 (mean ± SD), CRM was not affected (81 ± 10% to 82 ± 13%). Before analgesia, CRM was 84 ± 10%. CRM at 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes, and 60 minutes after analgesia was 82 ± 11%, 83 ± 14%, 83 ± 15%, 86 ± 12%, 89 ± 9%, and 87 ± 10%, respectively. There was a transient 2% reduction followed by a 5% increase in CRM from before to after epidural anesthesia (p = 0.048). Pain scores before and after analgesia were 7 ± 2 and 1 ± 1, respectively (p < 0.001). These results indicate that pain and analgesia contribute minimally, but independently to the reduction in compensatory reserve associated with trauma and hemorrhage. As such, our findings suggest that analgesia can be safely administered on the battlefield while maintaining the maximal capacity of mechanisms to compensate for blood loss.

    Full Text Available Aquapuncture (AqP consists of a water or saline solution injection into acupoints. This study aimed to evaluate the effect of aquapuncture on post-operative analgesia in bitches submitted to elective ovariohysterectomy (OHE. The study was prospective, randomised, and blinded for pain assessment. Sixteen dogs were randomly distributed in two groups of eight animals each. All animals were sedated with 0.05 mg kg-1 of acepromazine intramuscularly (IM, 30 minutes prior to induction of anaesthesia with propofol and maintenance with isoflurane. Eight animals underwent bilateral acupoint injection with 0.1 ml of 0.9% saline (AqP at Gall Bladder 34, Stomach 36, Liver 3 and Spleen 6 acupoints 15 minutes after sedation. Pain score was investigated after 0.5, 1, 2, 5, 8 and 24 hours post-operatively and was compared with a control untreated group of eight animals. Morphine, at 0.5 mg kg-1 IM, was administered when the numerical rating scale was above 33% of the maximum value, in order to control post-operative pain in both groups. There were no differences in cardiorespiratory variables and pain and sedation scores between the groups. Seven (87.5% animals from the control group required rescue analgesia at the first two postoperative hours and five (62.5% animals treated with AqP required rescue analgesia, however, only one (12.5% animal was treated at the first two hours and the remaining animals were treated from 5 hours after surgery. Aquapuncture produced residual analgesia up to 5 h after surgery and may be an option for post-operative analgesia in bitches undergoing OHE, providing that pain is assessed and rescue analgesia administered if necessary.

  17. Neonatal morphine enhances nociception and decreases analgesia in young rats.

    The recognition of the impact of neonatal pain experience on subsequent sensory processing has led to the increased advocacy for the use of opioids for pain relief in infants. However, following long-term opioid exposure in intensive care units more than 48% of infants exhibited behaviors indicative of opioid abstinence syndrome, a developmentally equivalent set of behaviors to opioid withdrawal as seen in adults. Little is known about the long-term influence of repeated neonatal morphine exposure on nociception and analgesia. To investigate this, we examined mechanical and thermal nociception on postnatal days 11, 13, 15, 19, 24, 29, 39 and 48 following subcutaneous administration of morphine (3 mg/kg) once daily on postnatal days 1-9. The cumulative morphine dose-response was assessed on postnatal days 20 and 49, and stress-induced analgesia was assessed on postnatal days 29 and 49. Both basal mechanical and thermal nociception in neonatal, morphine-exposed rats were significantly lower than those in saline-exposed, handled-control rats and naive rats until P29. A rightward-shift of cumulative dose-response curves for morphine analgesia upon chronic neonatal morphine was observed both on P20 and P49. The swim stress-induced analgesia was significantly decreased in neonatal morphine-exposed rats on P29, but not on P49. These data indicate that morphine exposure equivalent to the third trimester of gestation produced prolonged pain hypersensitivity, decreased morphine antinociception, and decreased stress-induced analgesia. The present study illustrates the need to examine the long-term influence of prenatal morphine exposure on pain and analgesia in the human pediatric population.

  1. Stellate ganglion blockade for analgesia following upper limb surgery.

    LENUS (Irish Health Repository)

    McDonnell, J G

    2012-01-31

    We report the successful use of a stellate ganglion block as part of a multi-modal postoperative analgesic regimen. Four patients scheduled for orthopaedic surgery following upper limb trauma underwent blockade of the stellate ganglion pre-operatively under ultrasound guidance. Patients reported excellent postoperative analgesia, with postoperative VAS pain scores between 0 and 2, and consumption of morphine in the first 24 h ranging from 0 to 14 mg. While these are preliminary findings, and must be confirmed in a clinical trial, they highlight the potential for stellate ganglion blockade to provide analgesia following major upper limb surgery.

    This project is concerned with long-term experiments to determine the lifespan dose-effect relationships of inhaled 239 PuO 2 and 238 PuO 2 in beagles. The data will be used to estimate the health effects of inhaled transuranics. Beagle dogs given a single exposure to 239 PuO 2 or 238 PuO 2 aerosols to obtain graded levels of initial lung burdens are being observed for lifespan dose-effect relationships. Mortality due to radiation pneumonitis and lung tumor increased in the four highest dose-level groups exposed to 239 PuO 2 , during the 13-yr postexposure period. During the 10 1/2 years after exposure to 238 PuO 2 , mortality due to lung and/or bone tumors increased in the three highest dose-level groups. Chronic lymphopenia, occurring 0.5 to 2 year after exposure, was the earliest observed effect after inhalation of either 239 PuO 2 or 238 PuO 2 in the four highest dose-level groups that had initial lung burdens greater than or equal to 80 nCi. 3 figures, 6 tables

  3. Cancer hazard from inhaled plutonium

    The best estimate of the lung cancer potential in humans for inhaled insoluble compounds of plutonium (such as PuO 2 particles) has been grossly underestimated by such authoritative bodies as the International Commission on Radiological Protection and the British Medical Research Council. Calculations are presented of lung cancer induction by 239 Pu as insoluble particles and for deposited reactor-grade Pu. The reason for the gross underestimate of the carcinogenic effects of Pu by ICRP or the British Medical Research Council (BMRC) is their use of a totally unrealistic idealized model for the clearance of deposited Pu from the lungs and bronchi plus their non-recognition of the bronchi as the true site for most human lung cancers. The erroneous model used by such organizations also fails totally to take into account the effect of cigarette-smoking upon the physiological function of human lungs. Plutonium nuclides, such as 239 Pu, or other alpha particle-emitting nuclides, in an insoluble form represent an inhalation cancer hazard in a class some 100,000 times more potent than the potent chemical carcinogens, weight for weight. The already-existing lung cancer data for beagle dogs inhaling insoluble PuO 2 particles is clearly in order of magnitude agreement with calculations for humans

  10. Information Models of Acupuncture Analgesia and Meridian Channels

    Full Text Available Acupuncture and meridian channels have been major components of Chinese and Eastern Asian medicine—especially for analgesia—for over 2000 years. In recent decades, electroacupuncture (EA analgesia has been applied clinically and experimentally. However, there were controversial results between different treatment frequencies, or between the active and the placebo treatments; and the mechanisms of the treatments and the related meridian channels are still unknown. In this study, we propose a new term of infophysics therapy and develop information models of acupuncture (or EA analgesia and meridian channels, to understand the mechanisms and to explain the controversial results, based on Western theories of information, trigonometry and Fourier series, and physics, as well as published biomedical data. We are trying to build a bridge between Chinese medicine and Western medicine by investigating the Eastern acupuncture analgesia and meridian channels with Western sciences; we model the meridians as a physiological system that is mostly constructed with interstices in or between other physiological systems; we consider frequencies, amplitudes and wave numbers of electric field intensity (EFI as information data. Our modeling results demonstrate that information regulated with acupuncture (or EA is different from pain information, we provide answers to explain the controversial published results, and suggest that mechanisms of acupuncture (or EA analgesia could be mostly involved in information regulation of frequencies and amplitudes of EFI as well as neuronal transmitters such as endorphins.

    Morphine and endorphin administered intracerebroventricularly (i.c.v.) produce analgesia by activating different descending pain inhibitory systems. Gamma irradiation attenuates the acute analgesic action of i.c.v. injected morphine in mice. This study was done to investigate the effect of-irradiation on the analgesia produced by i.c.v. injected morphine and endorphin in male ICR mice. In one group, mice were exposed to whole-body irradiation at a dose of 5 Gy from a {sup 60}Co source and the analgesic effects were tested 5, 30, 60, 90 and 180 min after irradiation using the acetic acid-induced writhing test. The analgesic effect was produced time-dependently and reached its maximum at 90 min after irradiation. Thus, time was fixed in the following studies. In another group, mice were irradiated with 5 Gy and tested 90 minutes later for analgesia produced by i.c.v. administration of morphine or endorphin. Irradiation significantly potentiated the analgesia produced by endorphin. However, the antinociception produced by morphine was not affected by irradiation. These results support the hypothesis that morphine and endorphin administered supraspinally produce antinocieception by different neuronal mechanisms.

    Epidural analgesia is one of the most popular modes of analgesia for child birth. There are controversies regarding adverse effects and safety of epidural analgesia. This study was conducted to study the immediate effects of the maternal epidural analgesia on the neonate during early neonatal phase. A prospective cohort study of 100 neonates born to mothers administered epidural analgesia were compared with 100 neonates born to mothers not administered epidural analgesia in terms of passage of urine, initiation of breast feeding, birth asphyxia and incidence of instrumentation. There was significant difference among the two groups in the passage of urine (P value 0.002) and incidence of instrumentation (P value 0.010) but there was no significant difference in regards to initiation of breast feeding and birth asphyxia. Epidural analgesia does not have any effect on the newborns in regards to breast feeding and birth asphyxia but did have effects like delayed passage of urine and increased incidence of instrumentation.

    Epidural analgesia is an effective and popular way to relieve labour pain but it may interfere with normal mechanism of labour. The objective of this study was to evaluate the outcome of labour in women with effective epidural analgesia in terms of duration of labour, mode of delivery and neonatal outcome. Methods: This was a quasi-experimental study conducted in the Department of Obstetrics and Gynaecology, Shaikh Zayed Federal Postgraduate Medical Institute and Hospital, Lahore. One hundred pregnant women were selected by non-probability convenient sampling method. Subjects were divided into two groups of 50 each as per convenience. Patients of any gravidity at term from 37-41 weeks were included in the sample. Epidural analgesia was applied to group B and distilled water to group A at the lumber region and the progress of labour, mode of delivery and effects on Apgar scores of neonates were evaluated. Out of hundred patients, 77 had normal duration of second stage while 23 had prolonged second stage. Among them, 18 patients (36%) were in epidural group and 5 patients (10%) in non-epidural group, while 4 patients (8%) in epidural group developed intra-partum complications; whereas among non-epidural group had such complications. 65 patients had spontaneous vaginal delivery while 35 patients had instrumental delivery. Among them 29 patients (58%) were in epidural group while only 6 patients (12%) were in non-epidural group. Babies born had Apgar score 5/10 (21.8%), 6/10 (59.4%) and 7/10 (17.8%) at 1 minute and 8/10 (74.3%) and 9/10 (24.8%) at 5 minutes in both groups and none of them needed bag and mask resuscitation. Conclusion: Epidural analgesia does prolong the duration of second stage of labour and increases the instrumental delivery rate. Neonatal outcome is satisfactory while only a few intra-partum complications are found with epidural analgesia. (author)

    Full Text Available Abstract Background Ciclesonide is a new inhaled corticosteroids licensed for the prophylactic treatment of persistent asthma in adults. Currently beclomethasone dipropionate, budesonide and fluticasone propionate are the most commonly prescribed inhaled corticosteroids for the treatment of asthma but there has been no systematic review comparing the effectiveness and safety ciclesonide to these agents. We therefore aimed to systematically review published randomised controlled trials of the effectiveness and safety of ciclesonide compared to alternative inhaled corticosteroids in people with asthma. Methods We performed literature searches on MEDLINE, EMBASE, PUBMED, the COCHRANE LIBRARY and various Internet evidence sources for randomised controlled trials or systematic reviews comparing ciclesonide to beclomethasone or budesonide or fluticasone in adult humans with persistent asthma. Data was extracted by one reviewer. Results Five studies met the inclusion criteria. Methodological quality was variable. There were no trials comparing ciclesonide to beclomethasone. There was no significant difference between ciclesonide and budesonide or fluticasone on the following outcomes: lung function, symptoms, quality of life, airway responsiveness to a provoking agent or inflammatory markers. However, the trials were very small in size, increasing the possibility of a type II error. One trial demonstrated that the combined deposition of ciclesonide (and its active metabolite in the oropharynx was 47% of that of budesonide while another trial demonstrated that the combined deposition of ciclesonide (and its active metabolite in the oropharynx was 53% of that of fluticasone. One trial demonstrated less suppression of cortisol in overnight urine collection after ciclesonide compared to fluticasone (geometric mean fold difference = 1.5, P Conclusion There is very little evidence comparing CIC to other ICS, restricted to very small, phase II studies of low

    We conducted the following inhalation injury experiment on dogs. A hose was connected to the chimney of a stove so that wood smoke could be led to the dog by means of damper adjustment. Under intravenous anesthesia, the dog was intubated and made to inhale the wood smoke for from 5 to 10 minutes at a smoke temperature of between 55 and 60 C. After this inhalation, observation of trachea by a fiberoptic bronchoscopy was done and blood gas change, blood analysis, serum electrolytes and cardiac output were observed with a passage of time. Furthermore, we did lung scan using 133xe and performed autopsies. We injected 0.3 microcurie of 133Xe per 1 kg body weight in its vein of the dog's foreleg. The concentration in the lung reached maximum 20 seconds after the injection and then washed out with expiration. In the control experiment with a normal dog, it was almost all washed out 70 seconds after the 133Xe injection. But the delay of wash out time was observed in smoke inhaled dogs. In other words it can be said that the wash out time was dependent on the degree of injury. When these data were processed by a computer, and exponential approximation decay curve was obtained. Then these data were replotted into semi-logarithmic chart and a linear line was obtained. One may interprete the clearance rate recorded on the graph as the ability of the lung to wash out 133Xe, that is, the degree of injury of the lung. The clearance rate had a tendancy to concentrate between 3.5 to 5.0 when observed 2 to 7 hours after the injury. However when observed 20 to 27 hours, concentration was between 2.4 to 3.2. Furthermore, the clearance rate for each lung regions were obtained and compared with one another by means of proper computer program. The clearance rate had lower values at lower region of lung, that is, deterioration of lung function was greater. (J.P.N.)

    Full Text Available OBJECTIVES: To evaluate the effects of intrathecal morphine on pulmonary function, analgesia, and morphine plasma concentrations after cardiac surgery. INTRODUCTION: Lung dysfunction increases morbidity and mortality after cardiac surgery. Regional analgesia may improve pulmonary outcomes by reducing pain, but the occurrence of this benefit remains controversial. METHODS: Forty-two patients were randomized for general anesthesia (control group n=22 or 400 µg of intrathecal morphine followed by general anesthesia (morphine group n=20. Postoperative analgesia was accomplished with an intravenous, patient-controlled morphine pump. Blood gas measurements, forced vital capacity (FVC, forced expiratory volume (FEV, and FVC/FEV ratio were obtained preoperatively, as well as on the first and second postoperative days. Pain at rest, profound inspiration, amount of coughing, morphine solicitation, consumption, and plasma morphine concentration were evaluated for 36 hours postoperatively. Statistical analyses were performed using the repeated measures ANOVA or Mann-Whiney tests (*p<0.05. RESULTS: Both groups experienced reduced FVC postoperatively (3.24 L to 1.38 L in control group; 2.72 L to 1.18 L in morphine group, with no significant decreases observed between groups. The two groups also exhibited similar results for FEV1 (p=0.085, FEV1/FVC (p=0.68 and PaO2/FiO2 ratio (p=0.08. The morphine group reported less pain intensity (evaluated using a visual numeric scale, especially when coughing (18 hours postoperatively: control group= 4.73 and morphine group= 1.80, p=0.001. Cumulative morphine consumption was reduced after 18 hours in the morphine group (control group= 20.14 and morphine group= 14.20 mg, p=0.037. The plasma morphine concentration was also reduced in the morphine group 24 hours after surgery (control group= 15.87 ng.mL-1 and morphine group= 4.08 ng.mL-1, p=0.029. CONCLUSIONS: Intrathecal morphine administration did not significantly alter

    Rib fractures are common in trauma admissions and are associated with an increased risk of pulmonary complications, intensive care unit admissions, and mortality. Providing adequate pain control in patients with multiple rib fractures decreases the risk of adverse events. Thoracic epidural analgesia is currently the preferred method for pain control. This study compared outcomes in patients with multiple acute rib fractures treated with posterior paramedian subrhomboidal (PoPS) analgesia versus thoracic epidural analgesia (TEA). This prospective study included 30 patients with three or more acute rib fractures admitted to a Level I trauma center. Thoracic epidural analgesia or PoPS catheters were placed, and local anesthesia was infused. Data were collected including patients' pain level, adjunct morphine equivalent use, adverse events, length of stay, lung volumes, and discharge disposition. Nonparametric tests were used and two-sided p Pain rating was lower in the PoPS group (2.5 vs. 5; p = 0.03) after initial placement. Overall, there was no other statistically significant difference in pain control or use of oral morphine adjuncts between the groups. Hypotension occurred in eight patients, 75% with TEA and only 25% with PoPS. No difference was found in adverse events, length of stay, lung volumes, or discharge disposition. In patients with rib fractures, PoPS analgesia may provide pain control equivalent to TEA while being less invasive and more readily placed by a variety of hospital staff. This pilot study is limited by its small sample size, and therefore additional studies are needed to prove equivalence of PoPS compared to TEA. Therapeutic study, level IV.

    The aim of this study was to examine whether sevoflurane in oxygen was equivalent to near equipotent concentrations of nitrous oxide in oxygen when used as an inhalation sedation agent in terms of patient and user acceptability. Forty anxious dental patients referred to the sedation suite at Cardiff University School of Dentistry received either nitrous oxide to a maximum concentration of 40% or sevoflurane to a maximum concentration of 0.3% for a routine maxillary plastic restoration with articaine infiltration local analgesia. The inhalation sedation agent to be administered was chosen by a random number allocator. Measurements of blood pressure, oxygen saturation, heart rate, respiratory rate and bispectral index were recorded every 5 minutes. At the end of the treatment episode the patient, the operator and an observer who was unaware of the agent used, recorded their impressions about the episode by completing questionnaires. In the doses used in this study, sevoflurane was found to be as effective as an inhalation sedation agent as the standard dose of nitrous oxide used in normal inhalation sedation in the treatment of adult anxious dental patients. Sevoflurane in low concentrations is equivalent in effect to near equipotent concentrations of nitrous oxide. This would suggest that further research, perhaps with slightly higher concentrations of sevoflurane, is needed. If sevoflurane was shown to be acceptable at slightly higher concentrations, there is scope to explore the development of equipment specifically designed to deliver sevoflurane as an inhalation sedation agent in future.

    The uranium ore milling process includes dusty operations and workers can be exposed to aerosols of highly concentrated uranium. Measurements made during uranium milling operations were used to predict that, if a worker was not wearing respiratory protection, 0.14-50 μg U/min might be deposited in the respiratory tract, predominantly in the nesopharyngeal compartment. Yellowcake was shown by infrared and solubility measurements to be a highly variable mixture of ammonium diuranate and U 3 O 8 . Biokinetic studies of inhaled yellowcake in beagle dogs showed that the more soluble fraction caused kidney damage. After inhalation of 0.5 mg U/kg body wt of soluble uranium, kidney concentration was 0.3 to 3.5 μg U/g kidney within 4-8 days; and was accompanied by kidney damage. Kidney damage was neither severe nor widespread, and was repaired within 64 days after exposure. The damage seen is due to heavy metal nephrotoxicity of uranium, and not to radiation damage

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

    The human respiratory system is an important route for the entry of inhaled therapeutics into the body to treat diseases. Inhaled materials may consist of gases, vapours, aerosols and particulates. In all cases, assessing the toxicological effect of inhaled therapeutics has many challenges. This article provides an overview of in vivo and in vitro models for testing the toxicity of inhaled therapeutics and nanoparticles implemented in drug delivery. Traditionally, inhalation toxicity has been performed on test animals to identify the median lethal concentration of airborne materials. Later maximum tolerable concentration denoted by LC0 has been introduced as a more ethically acceptable end point. More recently, in vitro methods have been developed, allowing the direct exposure of airborne material to cultured human target cells on permeable porous membranes at the air-liquid interface. Modifications of current inhalation therapies, new pulmonary medications for respiratory diseases and implementation of the respiratory tract for systemic drug delivery are providing new challenges when conducting well-designed inhalation toxicology studies. In particular, the area of nanoparticles and nanocarriers is of critical toxicological concern. There is a need to develop toxicological test models, which characterise the toxic response and cellular interaction between inhaled particles and the respiratory system.

    Full Text Available The term of inhalants is used for matters easily vapors. Inhalants are preferred for rapid, positive reinforcement and mild high effects. Products including inhalants are cheap, accessible, legal substances and are prevalently used in community. The prevalence of inhalant use in secondary schools in Turkey is about 5.1%. Inhalant substance dependence is generally observed within 14-15 age group. Age at first use could be as low as 5 to 6 years of age. Substance dependence is more probable in adults working in substance existing places. Inhalant usage is common in disadvantaged groups, children living in street, people with history of crimes, prison, depression, suicide, antisocial attitudes and conflict of family, history of abuse, violence and any other drug dependence and isolated populations. Inhalants are absorbed from lungs, after performing their quick and short effect metabolized by cytochrom P450 enzyme system except inhalant nitrites group which has a depressing effect like alcohol. In chronic use general atrophy, ventricular dilatation and wide sulcus were shown in cerebrum, cerebellum and pons by monitoring brain. Defects are mostly in periventricular, subcortical regions and in white matter. Demyelinization, hyperintensity, callosal slimming and wearing off in white and gray matter margins was also found. Ravages of brain shown by brain monitorisation are more and serious in inhalant dependence than in other dependences. It is important to decrease use of inhalants. Different approaches should be used for subcultures and groups in prevention. Prohibiting all the matters including inhalant is not practical as there are too many substances including inhalants. Etiquettes showing harmful materials can be used but this approach can also lead the children and adolescents recognize these substances easily.. Despite determintal effects of inhalant dependence, there are not yet sufficient number of studies conducted on prevention and

    We aimed to clarify whether the short-term adverse neonatal outcomes associated with epidural analgesia are due to the epidural analgesia itself or to the instrumental delivery. A retrospective case-control study was conducted to evaluate the relationship between epidural analgesia, labor length, and perinatal outcomes. A total of 350 pregnant women at term who delivered under epidural analgesia (cases) were compared with 1400 patients without epidural analgesia (controls). Vacuum extraction (6.5 vs. 2.9 %) and cesarean section (19.9 vs. 11.1 %) were more frequently performed in the cases than controls (p neonatal variables stratified by mode of delivery were not different in cases and controls, except for a slightly lower umbilical arterial pH in spontaneous delivery for the cases group. However, the Apgar scores and umbilical arterial pH were significantly lower in the neonates delivered by vacuum extraction compared with those in the neonates delivered by spontaneous delivery or cesarean section, regardless of whether epidural analgesia was performed. A multivariable analysis showed that vacuum extraction much more consistently affected the arterial pH than the analgesia itself (the β coefficients were -0.036 for epidural analgesia vs. -0.050 for vacuum extraction). Epidural analgesia was associated with slowly progressing labor, thus resulting in an increased rate of instrumental delivery. This instrumental delivery appears to adversely affect the neonatal outcomes more strongly than the analgesia itself.

    2006-12-01

    Full Text Available Abstract The interesting and important paper by Torvaldsen and colleagues provides further circumstantial evidence of a positive association between intrapartum analgesia and feeding infant formula. Not all research supports this association. Before 'failure to breastfeed' can be adjudged an adverse effect of intrapartum analgesia, the research evidence needs to be considered in detail. Examination of the existing evidence against the Bradford-Hill criteria indicates that the evidence is not yet conclusive. However, the difficulties of obtaining funding and undertaking large trials to explore putative adverse drug reactions in pregnant women may mean that we shall never have conclusive evidence of harm. Therefore, reports of large cohort studies with regression models, as in the paper published today, assume a greater importance than in other areas of investigation. Meanwhile, women and their clinicians may feel that sufficient evidence has accumulated to justify offering extra support to establish breastfeeding if women have received high doses of analgesics in labour.

    Full Text Available Acupuncture anesthesia has been practiced in China since about 1960. In Japan, Hyodo reported 30 cases of acupuncture anesthesia in 1972. However, from around 1980, the direction of acupuncture investigations turned from anesthesia to analgesia. Acupuncture analgesia is presently considered a way to activate the body's endogenous analgesic system. Recently, with the rise of acupuncture as one of the most well known CAM therapies, acupuncture or moxibustion treatment has been reported for both acute and chronic pain. Even so, few clinical reports and original articles have been reported in Japan. This review illustrates how acupuncture is being used in Japan for acute pain such as surgical operations, post- operative pain (POP, neuropathic pain, pain associated with teeth extractions and after the extraction of impacted wisdom teeth.

    This survey investigated the common practice of obstetric analgesia and anaesthesia in Swiss hospitals and evaluated the influence of the Swiss interest group for obstetric anaesthesia. In March 1999 we submitted 145 questionnaires to all Swiss hospitals providing an obstetric service. The rate of epidural analgesia (EA) was higher in large hospitals (> 1,000 births/year) than in small services. EA was maintained by continuous infusion techniques in 53% of the responding hospitals. For elective caesarean section, spinal anaesthesia (SA) and EA were performed in 77% and 16% of the patients, respectively. General anaesthesia (5%) was only used in small hospitals (interest group for obstetric anaesthesia, as well as the expectations of pregnant women, increased the numbers of regional anaesthesia compared with the first survey in 1992.

    This case report presents a case of symptomatic methemoglobinemia (MetHb 31.6%) after inhalation of volatile nitrites (poppers). The patient's medical history and symptoms are discussed together with pathophysiology of methemoglobinemia, diagnostics, and antidote therapy. Pulse oxymetry, arterial blood gas analysis, and CO-oximetry receive particular attention as well as antidote therapy with methylene blue. The patient was treated successfully with intravenous methylene blue. Within 60 min methemoglobinemia returned to normal values (MetHb 0.6%). Stimulating compounds such as volatile nitrites (poppers) may lead to potentially fatal methemoglobinemia. Swift and accurate diagnosis and targeted therapy with methylene blue can lead to rapid recovery.

    Full Text Available The study investigates parturients’ satisfaction with intrapartum analgesia. It aims to assess their opinions about hospital and health staff involved in delivery, besides investigating emotional control, locus control and bond between mothers and their newborn infants. A multidimensional approach has been used to investigate the variable of woman as a person, the variable of context and the variable of bond with the newborn infant. The study was conducted according to a quasi-experimental design, with a control group. The study was performed within the Analgesia and Intensive Care Operational Unit of the Maternal-Infant Department of the P. Giaccone University General Hospital of Palermo. It involved 60 women subdivided into two groups of 30 women each, the experimental group (women who requested intrapartum analgesia called the A group, and the control group (women who refused it called the B group. The following tools were administered: the STAI-Y (State-Trait Anxiety Inventory, form Y scale; the Depression Questionnaire of CBA (Cognitive Behavioural Assessment scale; the Locus of Control questionnaire; and an interview designed for the purpose. The experimental A group women exhibited lower levels of state anxiety and depression post-partum than those of the control B group; moreover, the women in the A group exhibited higher levels of external locus of control and evaluated delivery more positively than those of the B group. There were no significant differences with regard to the relationship with their newborn infants. The study shows that intrapartum analgesia provides hospitals with the possibility to satisfy women’s needs for safety and well-being.

    1997-06-01

    Lumbar epidural analgesia (LEA) decreases maternal stress as measured by maternal circulating plasma catecholamine concentrations. Intrathecal fentanyl (ITF) provides effective labour analgesia but its effect on maternal epinephrine (Epi) and norepinephrine (NE) concentrations is not known. This study assesses whether ITF reduces maternal stress in the same manner as conventional LEA. Twenty-four healthy women in active labour received either 25 micrograms ITF (n = 12) or epidural lidocaine 1.5% (n = 12) for analgesia. Venous blood samples were collected before anaesthesia and at five minute intervals for 30 min following anaesthesia for the measurement of plasma Epi and NE by high performance liquid chromatography. Maternal blood pressure (BP), heart rate (HR), visual analog scores (VAS) to pain and pruritus were recorded at the same time. Both ITF and LEA decreased pain VAS scores, maternal BP, and plasma Epi concentrations with only minimal effects on plasma NE concentrations. Intrathecal fentanyl (ITF) and LEA reduced plasma epi to a similar extent, with ITF reducing the levels slightly faster than LEA. Intrathecal fentanyl(ITF) and LEA reduced plasma Epi concentrations by 52% and 51%, respectively (P value < 0.01). We conclude that ITF is as effective as LEA in producing pain relief in the labouring patient. Intrathecal Fentanyl (ITF) is also capable of reducing maternal plasma epinephrine concentration, thus avoiding the possibly deleterious side effects of excess amounts of this catecholamine during labour.

    Pain management and sedation is a priority in neonatal intensive care units. A study was designed with the aim of determining current clinical practice as regards sedation and analgesia in neonatal intensive care units in Spain, as well as to identify factors associated with the use of sedative and analgesic drugs. A multicenter, observational, longitudinal and prospective study. Thirty neonatal units participated and included 468 neonates. Of these, 198 (42,3%) received sedatives or analgesics. A total of 19 different drugs were used during the study period, and the most used was fentanyl. Only fentanyl, midazolam, morphine and paracetamol were used in at least 20% of the neonates who received sedatives and/or analgesics. In infusions, 14 different drug prescriptions were used, with the most frequent being fentanyl and the combination of fentanyl and midazolam. The variables associated with receiving sedation and/or analgesia were, to have required invasive ventilation (P3 (P=.023; OR=2.26), the existence of pain evaluation guides in the unit (Pneonates admitted to intensive care units receive sedatives or analgesics. There is significant variation between Spanish neonatal units as regards sedation and analgesia prescribing. Our results provide evidence on the "state of the art", and could serve as the basis of preparing clinical practice guidelines at a national level. Copyright © 2015 Asociación Española de Pediatría.

    Optimal obstetric and neonatal care requires the provision of adequate analgesia for painful procedures. However, anesthetic and analgesic agents have the potential to adversely impact the developing fetal/neonatal brain. In this setting, clinicians must assess the risks and benefits of pharmacologic anesthesia and analgesia for specific indications in this population. General anesthesia is required for non-obstetric surgery and cesarean section in the absence of neuraxial anesthesia for the health of the mother and fetus. Although experimental data raise concerns, human data are reassuring and future research may focus on neuroprotective adjuncts in the setting of repeated or prolonged anesthetic exposures. Opioid analgesia is standard of care for preterm infants undergoing major procedures including invasive surgery and endotracheal intubation. The use of opioids for agitation resulting from mechanical ventilation is controversial, but prevalent. Randomized and retrospective studies detect short-term toxicity with inconclusive long-term impact, suggesting the need to explore alternative therapies. Copyright © 2017 Elsevier Ltd.

A loading dose of 0.5% plain bupivacaine was given to produce sensory analgesia (pin prick) from T4 to S5 and followed by a continuous infusion of 0.......5% plain bupivacaine 8 ml h-1. Pain, scored on a 5-point scale, and sensory analgesia were assessed hourly for 16 h after skin incision. If sensory analgesia decreased by more than 5 segments from its preoperative level, or if the pain score reached 2 (moderate pain), the patients were removed from...

    Full Text Available Background : Often conventional Inhalational agents are used for maintenance of anaesthesia in spine surgery. This study was undertaken to compare propofol with isoflurane anaesthesia with regard to haemodynamic stability, early emergence, postoperative nausea and vomiting (PONV and early assessment of neurological functions. Patients & Methods: Eighty ASA grade I &II adult patients were randomly allocated into two groups. Patients in study group received inj propofol for induction as well as for maintenance along with N 2O+O2 and the control group patients received inj thiopentone for induction and N 2 O+O 2 +isoflurane for maintenance. BIS monitoring was used for titrating the anaesthetic dose adjustments in all patients. All patients received fentanyl boluses for intraoperative analgesia and atracurium as muscle relaxant. Statistical data containing haemodynamic parameters, PONV, emergence time, dose of drug consumed & quality of surgical field were recorded and compared using student t′ test and Chi square test. Results: The haemodynamic stability was coparable in both the groups. The quality of surgical field were better in study group. Though there was no significant difference in the recovery profile (8.3% Vs 9.02% between both the groups, the postoperative nausea and vomiting was less in propofol group than isoflurane group (25%Vs60%. The anaesthesia cost was nearly double for propofol than isoflurane anaesthesia. Conclusion: Haemodynamic stability was comparable in both the groups. There was no significant difference in the recovery time between intravenous and inhalational group. Patients in propofol group were clear headed at awakening and were better oriented to place than inhalational group.

    Tverskoy, M.; Gelman, S.; Fowler, K.C.; Bradley, E.L.

    1985-01-01

    This study was designed to evaluate the influence of inhalational agents on the intestinal circulation in an isolated loop preparation. Sixty dogs were studied, using three intestinal segments from each dog. Selected intestinal segments were pumped with aortic blood at a constant pressure of 100 mmHg. A mixture of 86 Rb and 9-microns spheres labeled with 141 Ce was injected into the arterial cannula supplying the intestinal loop, while mesenteric venous blood was collected for activity counting. A very strong and significant correlation was found between rubidium clearance and microsphere entrapment (r = 0.97, P less than 0.0001). Nitrous oxide anesthesia was accompanied by a higher vascular resistance (VR), lower flow (F), rubidium clearance (Cl-Rb), and microspheres entrapment (Cl-Sph) than pentobarbital anesthesia, indicating that the vascular bed in the intestinal segment was constricted and flow (total and nutritive) decreased. Halothane, enflurane, and isoflurane anesthesia were accompanied by a much lower arteriovenous oxygen content difference (AVDO 2 ) and oxygen uptake than pentobarbital or nitrous oxide. Compared with pentobarbital, enflurane anesthesia was not accompanied by marked differences in VR, F, Cl-Rb, and Cl-Sph; halothane at 2 MAC decreased VR and increased F and Cl-Rb while isoflurane increased VR and decreased F. alpha-Adrenoceptor blockade with phentolamine (1 mg . kg-1) abolished isoflurane-induced vasoconstriction, suggesting that the increase in VR was mediated via circulating catecholamines

  8. Impact of Analgesia on the Course of Spontaneous Labor in Women with Diabetes Mellitus

    Directory of Open Access Journals (Sweden)

    M. I. Neimark

    2013-01-01

    Full Text Available Objective: to improve the results of spontaneous labor in female patients with diabetes mellitus (DM. Subjects and methods. The results of physiological labor analgesia were analyzed in 140 patients. The parturients were divided into 3 groups: 1 40 parturients in whom analgesia was performed by the intravenous administration of promedol; 2 40 parturients in whom analgesia was done by the fractional administration of 0.2% ropivacaine hydrochloride into the epidural space; 3 40 parturients in whom analgesia was carried out with intravenous paracetamol 2000—3000 mg. In all the patients, the investigators estimated central hemodynamic parameters by echocardiography, the efficiency of labor analgesia according to the scale described by N. N. Rasstrigina and B. V. Shnaider, as well as blood glucose levels, fetal status by a cardiotocographic technique, and neonatal status by Apgar scores at 1 and 5 minutes of life. Results. Analgesia quality assessment established that the best analgesic effect was achieved in the patients in Group 2 where 75.0% of the parturients had 8—10 scores. A comparative analysis of carbohydrate metabolic parameters also ascertained that the most steady-state and physiological glycemic level was recorded in Group 2 patients throughout the study. In addition, epidural analgesia versus other analgesic techniques provides the most steady-state hemodynamic parameters during labor, which promotes improved labor and has a beneficial effect on fetal and neonatal states. Conclusion. Glycemic levels during labor and delivery can be optimized in patients with DM only if adequate analgesia is achieved. By ensuring adequate labor analgesia, epidural analgesia normalizes glycemic and central hemodynamic parameters, favors elimination of delivery abnormalities, and has a beneficial effect on fetal and neonatal states. Key words: epidural analgesia, diabetes mellitus, spontaneous labor.

    Randomized, controlled pilot trial. The present study is the first randomized, double-blind, sham-controlled pilot clinical trial of transcranial direct current stimulation (tDCS) for pain and patient-controlled analgesia (PCA) opioid usage among patients receiving spine surgery. Lumbar spinal surgeries are common, and while pain is often a complaint that precedes surgical intervention, the procedures themselves are associated with considerable postoperative pain lasting days to weeks. Adequate postoperative pain control is an important factor in determining recovery and new analgesic strategies are needed that can be used adjunctively to existing strategies potentially to reduce reliance on opioid analgesia. Several novel brain stimulation technologies including tDCS are beginning to demonstrate promise as treatments for a variety of pain conditions. Twenty-seven patients undergoing lumbar spine procedures at Medical University of South Carolina were randomly assigned to receive four 20-minute sessions of real or sham tDCS during their postsurgical hospital stay. Patient-administered hydromorphone usage was tracked along with numeric rating scale pain ratings. The effect of tDCS on the slope of the cumulative PCA curve was significant (P tDCS was associated with a 23% reduction in PCA usage. In the real tDCS group a 31% reduction was observed in pain-at-its-least ratings from admission to discharge (P = 0.027), but no other changes in numeric rating scale pain ratings were significant in either group. The present pilot trial is the first study to demonstrate an opioid sparing effect of tDCS after spine surgical procedures. Although this was a small pilot trial in a heterogeneous sample of spinal surgery patients, a moderate effect-size was observed for tDCS, suggesting that future work in this area is warranted. 2.

    Opioids are commonly used as an epidural adjuvant to local anesthetics, but are associated with potentially serious side effects, such as respiratory depression. The aim of this study was to compare the efficacy and safety of dexmedetomidine with that of fentanyl as an adjuvant to epidural ropivacaine in pediatric orthopedic surgery. This study enrolled 60 children (3-12 years old) scheduled for orthopedic surgery of the lower extremities and lumbar epidural patient-controlled analgesia (PCA). Children received either dexmedetomidine (1 μg/kg) or fentanyl (1 μg/kg) along with 0.2% ropivacaine (0.2 mL/kg) via an epidural catheter at 30 minutes before the end of surgery. Postoperatively, the children were observed for ropivacaine consumption via epidural PCA, postoperative pain intensity, need for rescue analgesics, emergence agitation, and other adverse effects. The mean dose of bolus epidural ropivacaine was significantly lower within the first 6 h after surgery in the dexmedetomidine group, compared with the fentanyl group (0.029±0.030 mg/kg/h vs. 0.053±0.039 mg/kg/h, p=0.012). The median pain score at postoperative 6 h was also lower in the dexmedetomidine group, compared to the fentanyl group [0 (0-1.0) vs. 1.0 (0-3.0), p=0.039]. However, there was no difference in the need for rescue analgesia throughout the study period between groups. The use of dexmedetomidine as an epidural adjuvant had a significantly greater analgesic and local anesthetic-sparing effect, compared to fentanyl, in the early postoperative period in children undergoing major orthopedic lower extremity surgery. © Copyright: Yonsei University College of Medicine 2017

    Full Text Available Background: A major challenge in the postoperative period is pain management which, if not adequately controlled, may contribute to patient discomfort and decreased patient satisfaction, and possibly increased morbidity and mortality. Both Thoracic paravertebral block and oblique subcostal transversus abdominis plane block can be used as analgesic techniques for abdominal surgeries. Our aim in this research was comparison of cumulative 24-h post-operative morphine consumption between ultrasound-guided oblique subcostal transversus abdominis plane block and ultrasound-guided thoracic paravertebral block in patients who underwent an open cholecystectomy under general anesthesia. Patients and methods: This study was performed on 46 patients who underwent open cholecystectomy under general anesthesia. All patients were randomly allocated alternatively to one of two equal groups to either undergo ultrasound-guided unilateral oblique subcostal transversus abdominis plane block Group (I or to undergo ultrasound-guided unilateral thoracic paravertebral block Group (II. Both groups were subjected to a similar analgesic regimen in the immediate post-operative period that involved intravenous patient-controlled morphine analgesia which was used in both groups. Results: The total morphine consumption in the first postoperative 24 h was lower in thoracic paravertebral block Group (II (9.9 mg in thoracic paravertebral block group vs. 15.4 mg in oblique subcostal transversus abdominis plane block Group (I with p < 0.001. The mean time of first request of analgesia in Group (I was 248.7 min compared to 432.1 for Group (II with p < 0.001. Conclusions: Both ultrasound-guided oblique subcostal transversus abdominis plain block and single injection ultrasound guided thoracic paravertebral block are effective analgesic techniques for upper abdominal surgeries and reduces postoperative opioid requirements. However, thoracic paravertebral block is more

    The purpose of this study is to analyze whether supplementation of general anesthesia (GA) with thoracic epidural analgesia (TEA) for right lobe donor hepatectomy is a safe modality of pain relief in terms of changes in postoperative coagulation profile, incidence of epidural catheter-related complications, and timing of removal of epidural catheter. Retrospective analysis of the record of 104 patients who received TEA for right lobe donor hepatectomy was done. Platelet count, international normalized ratio, alanine aminotransferase, and aspartate aminotransferase were recorded postoperatively until the removal of the epidural catheter. The day of removal of the epidural catheter and visual analogue scale (VAS) scores were also recorded. Any complication encountered was documented. Intraoperatively, central venous pressure (CVP), hemodynamic variables, and volume of intravenous fluids infused were also noted. Statistical analysis was performed by using SPSS statistical package, version 17.0 (SPSS Inc. Chicago, IL). Continuous variables were presented as mean ± standard deviation. A total of 90% of patients had mean VAS scores between 1 and 4 in the postoperative period between days 1 and 5. None of the patients had a VAS score above 5. Although changes in coagulation status were encountered in all patients in the postoperative period, these changes were transient and did not persist beyond postoperative day (POD) 5. There was no delay in removal of the epidural catheter, and the majority of patients had the catheter removed by POD 4. There was no incidence of epidural hematoma. Aside from good intraoperative and postoperative analgesia, TEA in combination with balanced GA and fluid restriction enabled maintenance of low CVP and prevention of hepatic congestion. In conclusion, vigilant use of TEA appears to be safe during donor hepatectomy. Living liver donors should not be denied efficient analgesia for the fear of complications.

    Diclofenac dosing in children for analgesia is currently extrapolated from adult data. Oral diclofenac 1.0 mg·kg(-1) is recommended for children aged 1-12 years. Analgesic effect from combination diclofenac/acetaminophen is unknown. Children (n = 151) undergoing tonsillectomy (c. 1995) were randomized to receive acetaminophen elixir 40 mg·kg(-1) before surgery and 20 mg·kg(-1) rectally at the end of surgery with diclofenac suspension 0.1 mg·kg(-1) , 0.5 mg·kg(-1) , or 2.0 mg·kg(-1) before surgery or placebo. A further 93 children were randomized to receive diclofenac 0.1 mg·kg(-1) , 0.5 mg·kg(-1) , or 2.0 mg·kg(-1) only. Postoperative pain was assessed (visual analogue score, VAS 0-10) at half-hourly intervals from waking until discharge. Data were pooled with those from a further 222 children and 30 adults. One-compartment models with first-order absorption and elimination described the pharmacokinetics of both medicines. Combined drug effects were described using a modified EMAX model with an interaction term. An interval-censored model described the hazard of study dropout. Analgesia onset had an equilibration half-time of 0.496 h for acetaminophen and 0.23 h for diclofenac. The maximum effect (EMAX ) was 4.9. The concentration resulting in 50% of EMAX (C50 ) was 1.23 mg·l(-1) for diclofenac and 13.3 mg·l(-1) for acetaminophen. A peak placebo effect of 6.8 occurred at 4 h. Drug effects were additive. The hazard of dropping out was related to pain (hazard ratio of 1.35 per unit change in pain). Diclofenac 1.0 mg·kg(-1) with acetaminophen 15 mg·kg(-1) achieves equivalent analgesia to acetaminophen 30 mg·kg(-1) . Combination therapy can be used to achieve similar analgesia with lower doses of both drugs. © 2014 John Wiley & Sons Ltd.

    Pain during childbirth is arguably the most severe pain some women may experience in their lifetime. Epidural analgesia is an effective form of pain relief during labour. Many women have concerns regarding its safety. Furthermore, epidural services and anaesthetic support may not be available consistently across all centres. Observational data suggest that early initiation of epidural may be associated with an increased risk of caesarean section, but the same findings were not seen in recent randomised controlled trials. More recent guidelines suggest that in the absence of a medical contraindication, maternal request is a sufficient medical indication for pain relief during labour. The choice of analgesic technique, agent, and dosage is based on many factors, including patient preference, medical status, and contraindications. There is no systematically reviewed evidence on the maternal and foetal outcomes and safety of this practice. This systematic review aimed to summarise the effectiveness and safety of early initiation versus late initiation of epidural analgesia in women. We considered the obstetric and fetal outcomes relevant to women and side effects of the treatments, including risk of caesarean section, instrumental birth and time to birth. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (12 February 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE (January 1966 to February 2014), Embase (January 1980 to February 2014) and reference lists of retrieved studies. We included all randomised controlled trials involving women undergoing epidural labour analgesia that compared early initiation versus late initiation of epidural labour analgesia. Two review authors independently assessed trials for inclusion, extracted the data and assessed the trial quality. Data were checked for accuracy. We included nine studies with a total of 15,752 women.The overall risk of bias of

    Full Text Available Shinsuke Tanizaki Department of Emergency Medicine, Fukui Prefectural Hospital, Fukui, Japan Abstract: Respiratory tract injuries caused by inhalation of smoke or chemical products are related to significant morbidity and mortality. While many strategies have been built up to manage cutaneous burn injuries, few logical diagnostic strategies for patients with inhalation injuries exist and almost all treatment is supportive. The goals of initial management are to ensure that the airway allows adequate oxygenation and ventilation and to avoid ventilator-induced lung injury and substances that may complicate subsequent care. Intubation should be considered if any of the following signs exist: respiratory distress, stridor, hypoventilation, use of accessory respiratory muscles, blistering or edema of the oropharynx, or deep burns to the face or neck. Any patients suspected to have inhalation injuries should receive a high concentration of supplemental oxygen to quickly reverse hypoxia and to displace carbon monoxide from protein binding sites. Management of carbon monoxide and cyanide exposure in smoke inhalation patients remains controversial. Absolute indications for hyperbaric oxygen therapy do not exist because there is a low correlation between carboxyhemoglobin levels and the severity of the clinical state. A cyanide antidote should be administered when cyanide poisoning is clinically suspected. Although an ideal approach for respiratory support of patients with inhalation injuries do not exist, it is important that they are supported using techniques that do not further exacerbate respiratory failure. A well-organized strategy for patients with inhalation injury is critical to reduce morbidity and mortality. Keywords: inhalation injury, burn, carbon monoxide poisoning, cyanide poisoning

    Several agents are used to clear secretions from the airways of people with cystic fibrosis. Mannitol increases mucociliary clearance, but its exact mechanism of action is unknown. The dry powder formulation of mannitol may be more convenient and easier to use compared with established agents which require delivery via a nebuliser. Phase III trials of inhaled dry powder mannitol for the treatment of cystic fibrosis have been completed and it is now available in Australia and some countries in Europe. This is an update of a previous review. To assess whether inhaled dry powder mannitol is well tolerated, whether it improves the quality of life and respiratory function in people with cystic fibrosis and which adverse events are associated with the treatment. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic databases, handsearching relevant journals and abstracts from conferences.Date of last search: 28 September 2017. All randomised controlled studies comparing mannitol with placebo, active inhaled comparators (for example, hypertonic saline or dornase alfa) or with no treatment. Authors independently assessed studies for inclusion, carried out data extraction and assessed the risk of bias in included studies. The quality of the evidence was assessed using GRADE. Six studies (reported in 50 publications) were included with a total of 784 participants.Duration of treatment in the included studies ranged from 12 days to six months, with open-label treatment for an additional six months in two of the studies. Five studies compared mannitol with control (a very low dose of mannitol or non-respirable mannitol) and the final study compared mannitol to dornase alfa alone and to mannitol plus dornase alfa. Two large studies had a similar parallel design and provided data for 600 participants, which could be pooled where data for a particular outcome and time point were

    The requirement for post-operative analgesia after ovariohysterectomy (OH) versus orchiectomy in dogs and cats was compared. Twelve male and 12 female cats and 12 male and 12 female dogs received meloxicam, 0.1 mg/kg body weight, PO, 2 h before surgery. Eleven female cats and 3 female dogs received rescue analgesia ( P = 0.002). No male of either species required rescue analgesia. The number of cats receiving rescue analgesia was greater in females than in males ( P dogs or cats. Postoperative pain after OH should be assessed for at least 2 h for cats and 4 h for dogs, using species-specific validated tools, to ensure proper postoperative pain diagnosis and management. Male dogs and cats subjected to orchiectomy required less postoperative analgesia intervention than female dogs and cats submitted to OH.

However, such mixtures are not commercially available, and the stability of the drug combinations has not been duly studied. The study aimed to evaluate the stability of tramadol with three 5-HT3 receptor antagonists in 0.9% sodium chloride injection for PCA administration.Materials and methods: Test samples were prepared by adding 1,000 mg tramadol hydrochloride, 8 mg ondansetron hydrochloride, and 6 mg granisetron hydrochloride or 5 mg tropisetron hydrochloride to 100 mL of 0.9% sodium chloride injection in polyolefin bags. The samples were prepared in triplicates, stored at either 25°C or 4°C for 14 days, and assessed using the following compatibility parameters: precipitation, cloudiness, discoloration, and pH. Chemical stability was also determined using a validated high-pressure liquid chromatography method.Results: All of the mixtures were clear and colorless throughout the initial observation period. No change in the concentration of tramadol hydrochloride occurred with any of the 5-HT3 receptor antagonists during the 14 days. Similarly, little or no loss of the 5-HT3 receptor antagonists occurred over the 14-day period.Conclusion: Our results suggest that mixtures of tramadol hydrochloride, ondansetron hydrochloride, granisetron hydrochloride, or tropisetron hydrochloride in 0.9% sodium chloride injection were physically and chemically stable for 14 days when stored in polyolefin bags at both 4°C and 25°C.

    Brain responses to pain experienced by oneself or seen in other people show consistent overlap in the pain processing network, particularly anterior insula, supporting the view that pain empathy partly relies on neural processes engaged by self-nociception. However, it remains unresolved whether changes in one's own pain sensation may affect empathic responding to others' pain. Here we show that inducing analgesia through hypnosis leads to decreased responses to both self and vicarious experience of pain. Activations in the right anterior insula and amygdala were markedly reduced when participants received painful thermal stimuli following hypnotic analgesia on their own hand, but also when they viewed pictures of others' hand in pain. Functional connectivity analysis indicated that this hypnotic modulation of pain responses was associated with differential recruitment of right prefrontal regions implicated in selective attention and inhibitory control. Our results provide novel support to the view that self-nociception is involved during empathy for pain, and demonstrate the possibility to use hypnotic procedures to modulate higher-level emotional and social processes.

    There is little information regarding changes in placebo responsiveness with age, although first predictors of placebo responders such as psychological and physiological processes have been identified. Reviews and meta-analyses indicate that placebo response rates in randomized controlled trials (RCTs) are higher in children and adolescents compared with adults. As these studies cannot control for age-dependent differences in the natural course of the disease, biases might contribute to different placebo rates in RCTs. To avoid these biases, this study investigated age-related differences in placebo responsiveness between children and adults in a well-established experimental model of placebo analgesia combining classic conditioning and expectation. Our data confirm placebo analgesic responses in children, which did not differ in magnitude from those of adults. The influence of previous experience on subsequent treatment outcome was stronger in children than in adults, indicating an increased relevance of learning processes for treatment outcomes in children. Further studies are needed to understand the influence of treatment-related learning processes in children and adolescents, which might critically determine treatment responsiveness during adulthood. This study is the first to experimentally explore placebo analgesia and influences of previous experience on placebo responses in children compared with adults. We found comparable placebo responses in both groups and an increased relevance of learning processes for treatment outcomes in children. Copyright © 2015 American Pain Society.

    It is well known that acupuncture has pain-relieving effects, but the contribution of specific and especially non-specific factors to acupuncture analgesia is less clear. One hundred and one patients who developed pain ≥ 3 on a visual analog scale (VAS, 0-10) following third molar surgery were randomized to receive active acupuncture, placebo acupuncture, or no treatment for 30 min with acupuncture needles with potential for double-blinding. Patients’ perception of the treatment (active or placebo), and expected pain levels (VAS) were assessed prior to and halfway through the treatment. Looking at actual treatment allocation, there was no specific effect of active acupuncture (P = 0.240), but a large and significant non-specific effect of placebo acupuncture (P acupuncture (P acupuncture had significantly lower pain levels than those who believed they received placebo acupuncture. Expected pain levels accounted for significant and progressively larger amounts of the variance in pain ratings following both active and placebo acupuncture (up to 69.8%), This is the first study to show that under optimized blinding conditions non-specific factors such as patients’ perception of and expectations toward treatment are central to the efficacy of acupuncture analgesia and that these factors may contribute to self-reinforcing effects in acupuncture treatment To obtain an effect of acupuncture in clinical practice it may, therefore, be important to incorporate and optimize these factors.

    Transcutaneous electrical nerve stimulation (TENS), as a non-pharmacological and non-invasive analgesic therapy with low-cost, has been widely used to relieve pain in various clinical applications, by delivering current pulses to the skin area to activate the peripheral nerve fibers. Nevertheless, analgesia induced by TENS varied in the clinical practice, which could be caused by the fact that TENS with different stimulus parameters has different biological mechanisms in relieving pain. Therefore, to advance our understanding of TENS in various basic and clinical studies, we discussed (1) neurophysiological and biochemical mechanisms of TENS-induced analgesia; (2) relevant factors that may influence analgesic effects of TENS from the perspectives of stimulus parameters, including stimulated position, pulse parameters (current intensity, frequency, and pulse width), stimulus duration and used times in each day; and (3) applications of TENS in relieving clinical pain, including post-operative pain, chronic low back pain and labor pain. Finally, we propose that TENS may involve multiple and complex psychological neurophysiological mechanisms, and suggest that different analgesic effects of TENS with different stimulus parameters should be taken into consideration in clinical applications. In addition, to optimize analgesic effect, we recommend that individual-based TENS stimulation parameters should be designed by considering individual differences among patients, e.g., adaptively adjusting the stimulation parameters based on the dynamic ratings of patients' pain.

    Rapid advances have been made in the use of pharmacological analgesia and sedation for newborns requiring neonatal intensive care. Practical considerations for the use of systemic analgesics (opioids, non-steroidal anti-inflammatory agents, other drugs), local and topical anaesthetics, and sedative or anaesthetic agents (benzodiazepines, barbiturates, other drugs) are summarised using an evidence-based medicine approach, while avoiding mention of the underlying basic physiology or pharmacology. These developments have inspired more humane approaches to neonatal intensive care. Despite these advances, little is known about the clinical effectiveness, immediate toxicity, effects on special patient populations, or long-term effects after neonatal exposure to analgesics or sedatives. The desired or adverse effects of drug combinations, interactions with non-pharmacological interventions or use for specific conditions also remain unknown. Despite the huge gaps in our knowledge, preliminary evidence for the use of neonatal analgesia and sedation is available, but must be combined with a clear definition of clinical goals, continuous physiological monitoring, evaluation of side effects or tolerance, and consideration of long-term clinical outcomes.

    The aim of this paper is to describe and evaluate the benefits of epidural anesthesia in major surgery neonatal. We have performed a matched case-control (2:1) study of patients undergoing neonatal major surgery (NMSs) who received intra-and postoperative epidural anesthesia (EA) and controls with conventional general anesthesia. The matching criteria were age, weight and baseline pathology. EA was administered by caudal puncture and epidural catheter placed with ultrasound support. Levobupivacaine was selected as anesthetic drug. The time to extubation, intestinal transit time, type of analgesia and complications were studied. This study is based on 11 cases (2 esophageal atresia, 2 diaphragmatic hernias, 1 necrotizing enterocolitis, 3 intestinal atresia, 2 anorectal malformation and 1 bladder exstrophy) and 22 controls. We observed statistically significant differences in time to extubation (95% CI OR 12 1.99 to 72.35; Chi2 p = 0.004, Mann U Whytney p = 0.013) and intestinal transit time (Mann Whitney U p analgesia. Therefore we believe that the intra-and postoperative EA helps improve postoperative management in neonates and should be preferred in centers where this technique is available.

    Full Text Available Background: Regional anesthetic techniques can be used to alleviate postoperative pain in patients undergoing major upper abdominal surgery. Our aim was to evaluate the efficacy of bilateral ultrasound (US-guided rectus sheath (RS and transversus abdominis plane (TAP blocks for better perioperative analgesia. Patients and Methods: It is a prospective, observer-blinded, randomized clinical study. 40 eligible patients undergoing elective liver resection or Whipple procedure were included. All patients received a standardized anesthetic technique. Group 1 (n = 20 received preincisional US-guided bilateral RS and TAP blocks using 20 ml volume of bupivacaine 0.25% for each, and group 2 (n = 20 received local wound infiltration at end of surgery with 40 ml of bupivacaine 0.25%. A standardized postoperative analgesic regimen composed of intravenous paracetamol and a morphine patient-controlled analgesia (PCA. The use of intraoperative fentanyl and recovery room morphine boluses, PCA-administered morphine, pain scores as well as number of patients′ experienced postoperative nausea and vomiting in the ward at 6 and 24 h were recorded. Results: Group 1 patients received a significantly lower cumulative intraoperative fentanyl, significantly lesser boluses of morphine in postanesthesia care unit, as well, significantly lower cumulative 24 h postoperative morphine dosage than the group 2 patients. Pain visual analog scale scores were significantly lower at both 6 and 24 h postoperatively in TAP group when compared with the no-TAP group. There were no complications related to the TAP block procedures. No signs or symptoms of local anesthetic systemic toxicity were detected. Conclusion: The combination of bilateral US-guided RS and TAP blocks provides excellent perioperative analgesia for major upper abdominal surgery.

    Full Text Available Background: Pain is the most common reason for medical consultation in the United States. Pain is a major symptom in many medical conditions, and can significantly interfere with a person’s quality of life and general functioning. One of the very unpleasant pain is toothache. Conventional treatments for toothache are improving oral hygiene, prescribing analgesics, anti-inflammatory, and also antibiotics if there are infection even extractions are performed if necessary. Another way to conventional approaches, patients may consider acupuncture method. Acupuncture involves the insertion of needles with the width of a human hair along the precise points throughout the body. This process triggers body’s energy normal flow through extra anatomy pathway called meridian. Purpose: This case report is aimed to emphasize the existence of teeth-organ relationships through communication channels outside the lines of communication that has been known in anatomy. Case: Two patients with toothache complaints in the lower right molars came to an acupuncturist who was a medical practitioner. In these cases pain were relieved by acupuncture analgesia. Case management: Two patients were subjected to acupuncture analgesia with different acupuncture points that were customized to the affected tooth, case 1 with the large intestine-4 (Li-4 which located in the hand and case 2 with bladder-25 (Bl-25 which located in the back of the body. Ninety percent of pain was relieved in 40 seconds. Conclusion: Pain in toothache can be relieved using acupuncture analgesia technique, using meridian as an extra anatomy pathway. Nevertheless, treating the source of pain by dental practitioner is mandatory.Latar belakang: Nyeri adalah alasan paling umum yang menyebabkan orang datang berkonsultasi kepada profesional medis di Amerika Serikat.

    Inhaled antibiotics have been used to treat chronic airway infections since the 1940s. The earliest experience with inhaled antibiotics involved aerosolizing antibiotics designed for parenteral administration. These formulations caused significant bronchial irritation due to added preservatives and nonphysiologic chemical composition. A major therapeutic advance took place in 1997, when tobramycin designed for inhalation was approved by the U.S. Food and Drug Administration (FDA) for use in patients with cystic fibrosis (CF) with chronic Pseudomonas aeruginosa infection. Attracted by the clinical benefits observed in CF and the availability of dry powder antibiotic formulations, there has been a growing interest in the use of inhaled antibiotics in other lower respiratory tract infections, such as non-CF bronchiectasis, ventilator-associated pneumonia, chronic obstructive pulmonary disease, mycobacterial disease, and in the post-lung transplant setting over the past decade. Antibiotics currently marketed for inhalation include nebulized and dry powder forms of tobramycin and colistin and nebulized aztreonam. Although both the U.S. Food and Drug Administration and European Medicines Agency have approved their use in CF, they have not been approved in other disease areas due to lack of supportive clinical trial evidence. Injectable formulations of gentamicin, tobramycin, amikacin, ceftazidime, and amphotericin are currently nebulized "off-label" to manage non-CF bronchiectasis, drug-resistant nontuberculous mycobacterial infections, ventilator-associated pneumonia, and post-transplant airway infections. Future inhaled antibiotic trials must focus on disease areas outside of CF with sample sizes large enough to evaluate clinically important endpoints such as exacerbations. Extrapolating from CF, the impact of eradicating organisms such as P. aeruginosa in non-CF bronchiectasis should also be evaluated.

    Mysterious deaths of archeologists after opening Egyptian tombs have been suspected to be secondary to inhalation of mycotoxin, however, the hypothesis has never been verified. Recently, we observed a case of acute renal failure (ARF) undeniably due to inhalation of ochratoxin of Aspergillus ochraceus. After spending 8 h in a granary which had been closed for several months, a farmer and his wife suffered temporary respiratory distress; 24 h later, the woman developed nonoliguric ARF and biopsy revealed tubulonecrosis which healed in 24 days. Toxic substances were not found, but a strain of A. ochraceus producing ochratoxin was isolated from the wheat.

    Placebo analgesia is an indicator of how efficiently the brain translates psychological signals conveyed by a treatment procedure into pain relief. It has been demonstrated that functional connectivity between distributed brain regions predicts placebo analgesia in chronic back pain patients. Greater network efficiency in baseline brain networks may allow better information transfer and facilitate adaptive physiological responses to psychological aspects of treatment. Here, we theorized that topological network alignments in resting state scans predict psychologically conditioned analgesic responses to acupuncture treatment in chronic knee osteoarthritis pain patients (n = 45). Analgesia was induced by building positive expectations toward acupuncture treatment with verbal suggestion and heat pain conditioning on a test site of the arm. This procedure induced significantly more analgesia after sham or real acupuncture on the test site than in a control site. The psychologically conditioned analgesia was invariant to sham versus real treatment. Efficiency of information transfer within local networks calculated with graph-theoretic measures (local efficiency and clustering coefficients) significantly predicted conditioned analgesia. Clustering coefficients in regions associated with memory, motivation, and pain modulation were closely involved in predicting analgesia. Moreover, women showed higher clustering coefficients and marginally greater pain reduction than men. Overall, analgesic response to placebo cues can be predicted from a priori resting state data by observing local network topology. Such low-cost synchronizations may represent preparatory resources that facilitate subsequent performance of brain circuits in responding to adaptive environmental cues. This suggests a potential utility of network measures in predicting placebo response for clinical use.

    Both gender-specific and gonadectomy-specific effects have been observed for the analgesic responses following continuous and intermittent cold-water swims (CCWS and ICWS respectively): female rats display significantly less analgesia than males, and gonadectomized rats display significantly less analgesia than sham-operated controls. The present study evaluated the effects of steroid replacement therapy with testosterone propionate (TP: 2 mg/kg, SC) upon CCWS and ICWS analgesia on the tail-flick and jump tests and hypothermia in sham-operated or gonadectomized male and female rats. Thirty days following surgery, rats received either no treatment, a sesame oil vehicle or TP for 14 days prior to, and then during testing. Relative to the no treatment condition, repeated vehicle injections in sham-operated rats eliminated the gender-specific, but did not affect the gonadectomy-specific effects upon CCWS and ICWS analgesia. TP reversed the deficits in CCWS and ICWS analgesia observed in both castrated and ovariectomized rats on both pain tests. TP only potentiated CCWS analgesia in sham-operated males on the tail-flick test. TP potentiated CCWS and ICWS hypothermia in gonadectomized rats and in male sham-operated rats. These data indicate that gonadal steroids play a major modulatory role in the etiology of swim analgesia, and that the observed gender effects are sensitive to possible adaptational variables.

    This study was conducted to determine whether exposure to RFR might induce sufficient thermal stress to activate endogenous opioid mechanisms and induce analgesia. Male Swiss Webster mice, 20-25 g, were exposed to 10, 15 or 20 mV/cm{sup 2} RFR in a 2,450-MHz waveguide system for 10 min, then tested in the abdominal constriction paradigm. Specific absorption rates (SAR) were 23.7 W/kg at 10 mW/cm{sup 2}, 34.6 W/kg at 15 mW/cm{sup 2} and 45.5 W/kg at 20 mW/cm{sup 2}. Confinement in the exposure chamber alone did not appreciably alter body temperature but did appear to induce a stress-associated analgesia that was insensitive to the opioid receptor blocker naltrexone. Exposure of confined mice to RFR elevated body temperature and further increased analgesia in SAR-dependent manner. The high-SAR RFR-induced analgesia, but not the hyperthermia, was reduced by naltrexone. These findings suggest that (1) RFR produces SAR-dependent hyperthermia and analgesia and (2) RFR-induced analgesia is mediated by opioid mechanisms while confinement-induced analgesia involves non-opioid mechanisms.

    The purpose of the study was to estimate the ability of L-tyrosine to induce cutaneous analgesia and to investigate the interaction between L-tyrosine and the local anesthetic lidocaine. After subcutaneously injecting the rats with L-tyrosine and lidocaine in a dose-dependent manner, cutaneous analgesia (by blocking the cutaneous trunci muscle reflex-CTMR) was evaluated in response to the local pinprick. The drug-drug interaction was analyzed by using an isobolographic method. We showed that both L-tyrosine and lidocaine produced dose-dependent cutaneous analgesia. On the 50% effective dose (ED50) basis, the rank of drug potency was lidocaine (5.09 [4.88-5.38] μmol)>L-tyrosine (39.1 [36.5-41.8] μmol) (Ptyrosine lasted longer than that caused by lidocaine (Ptyrosine exhibited an additive effect on infiltrative cutaneous analgesia. Our pre-clinical study demonstrated that L-tyrosine elicits the local/cutaneous analgesia, and the interaction between L-tyrosine and lidocaine is additive. L-tyrosine has a lower potency but much greater duration of cutaneous analgesia than lidocaine. Adding L-tyrosine to lidocaine preparations showed greater duration of cutaneous analgesia compared with lidocaine alone. Copyright © 2015 Elsevier B.V. All rights reserved.

    Maternal age is an established risk factor for cesarean section; epidural analgesia and oxytocin augmentation may modify this association. We investigated the effects and interactions of oxytocin augmentation, epidural analgesia and maternal age on the risk of cesarean section. In all, 416 386 nulliparous women with spontaneous onset of labor, ≥37 weeks of gestation and singleton infants with a cephalic presentation during 2000-2011 from Norway and Denmark were included [Ten-group classification system (Robson) group 1]. In this case-control study the main exposure was maternal age; epidural analgesia, oxytocin augmentation, birthweight and time period were explanatory variables. Chi-square test and logistic regression were used to estimate associations and interactions. The cesarean section rate increased consistently with advancing maternal age, both overall and in strata of epidural analgesia and oxytocin augmentation. We observed strong interactions between maternal age, oxytocin augmentation and epidural analgesia for the risk of cesarean section. Women with epidural analgesia generally had a reduced adjusted odds ratio when oxytocin was used compared with when it was not used. In Norway, this applied to all maternal age groups but in Denmark only for women ≥30 years. Among women without epidural, oxytocin augmentation was associated with an increased odds ratio for cesarean section in Denmark, whereas no difference was observed in Norway. Oxytocin augmentation in nulliparous women with epidural analgesia is associated with a reduced risk of cesarean section in labor with spontaneous onset. © 2018 Nordic Federation of Societies of Obstetrics and Gynecology.

    To describe the use and adverse effects of chloroprocaine for epidural analgesia in young infants for infusion durations greater than 3.5 hours. A retrospective cohort review of the electronic medical record over a 14-month period. The level IV neonatal intensive care unit of a 414-bed free-standing children's hospital. Eighteen infants (mean age, 1.7 ± 1.8 months [0.03-6.3]; mean weight, 3.8 ± 1.3 kg [1.56-6.9]; n = 10 [55%] males) received 1% chloroprocaine for epidural analgesia postoperatively for up to 96-hour duration and met criteria for inclusion. Dosing requirements, placement of epidural catheter, supplementary analgesic therapy, respiratory support, vital signs, and incidence of adverse events associated with local anesthetics were collected. Epidural catheter placement was caudal (n = 8), lumbar (n = 6), or thoracic (n = 4). Mean operative time was 2.48 ± 1 hour (1-5). Initial chloroprocaine dose was 1.3 ± 0.5 mL/h (0.4-2.5) (3.5 ± 1 mg/kg per hour [1.4-5]) with a maximum dose of 1.5 ± 0.6 mL/h (0.4-3) (4.2 ± 1.1 mg/kg per hour [2.2-6.1]). Duration of epidural analgesia was 48.3 ± 21.5 hours (10-96). Duration of epidural infusion did not influence dosing requirement, suggesting the absence of drug tachyphylaxis. All patients received intermittent doses of opioid and nonopioid pain medications while receiving chloroprocaine. Two mechanically ventilated patients required continuous infusion of opioids. No adverse events were directly attributed to chloroprocaine use. Epidural 1% chloroprocaine, in doses of 0.4-3 mL/h (1.5-6.1 mg/kg per hour), was well tolerated in both mechanically ventilated and spontaneously breathing infants for up to 96 hours with no identified adverse effects or tachyphylaxis.

    Full Text Available Abstract Background Most women use some method of pain relief during labour. There is extensive research evidence available of pharmacological pain relief during labour; however this evidence is not readily available to pregnant women. Decision aids are tools that present evidence based information and allow preference elicitation. Methods We developed a labour analgesia decision aid. Using a RCT design women either received a decision aid or a pamphlet. Eligible women were primiparous, ≥ 37 weeks, planning a vaginal birth of a single infant and had sufficient English to complete the trial materials. We used a combination of affective (anxiety, satisfaction and participation in decision-making and behavioural outcomes (intention and analgesia use to assess the impact of the decision aid, which were assessed before labour. Results 596 women were randomised (395 decision aid group, 201 pamphlet group. There were significant differences in knowledge scores between the decision aid group and the pamphlet group (mean difference 8.6, 95% CI 3.70, 13.40. There were no differences between decisional conflict scores (mean difference -0.99 (95% CI -3.07, 1.07, or anxiety (mean difference 0.3, 95% CI -2.15, 1.50. The decision aid group were significantly more likely to consider their care providers opinion (RR 1.28 95%CI 0.64, 0.95. There were no differences in analgesia use and poor follow through between antenatal analgesia intentions and use. Conclusions This decision aid improves women's labour analgesia knowledge without increasing anxiety. Significantly, the decision aid group were more informed of labour analgesia options, and considered the opinion of their care providers more often when making their analgesia decisions, thus improving informed decision making.

    Evidence exists that analgesics are underutilized, delayed, and insufficiently dosed for emergency department (ED) patients with acute abdominal pain. For physicians practicing in a Canadian paediatric ED setting, we (1) explored theoretical practice variation in the provision of analgesia to children with acute abdominal pain; (2) identified reasons for withholding analgesia; and (3) evaluated the relationship between providing analgesia and surgical consultation. Physician members of Paediatric Emergency Research Canada (PERC) were prospectively surveyed and presented with three scenarios of undifferentiated acute abdominal pain to assess management. A modified Dillman's Tailored Design method was used to distribute the survey from June to July 2014. Overall response rate was 74.5% (149/200); 51.7% of respondents were female and mean age was 44 (SD 8.4) years. The reported rates of providing analgesia for case scenarios representative of renal colic, appendicitis, and intussusception, were 100%, 92.1%, and 83.4%, respectively, while rates of providing intravenous opioids were 85.2%, 58.6%, and 12.4%, respectively. In all 60 responses where the respondent indicated they would obtain a surgical consultation, analgesia would be provided. In the 35 responses where analgesia would be withheld, 21 (60%) believed pain was not severe enough, while 5 (14.3%) indicated it would obscure a surgical condition. Pediatric emergency physicians self-reported rates of providing analgesia for acute abdominal pain scenarios were higher than previously reported, and appeared unrelated to request for surgical consultation. However, an unwillingness to provide opioid analgesia, belief that analgesia can obscure a surgical condition, and failure to take self-reported pain at face value remain, suggesting that the need exists for further knowledge translation efforts.

    To review barriers to the successful use of inhalers in patients with chronic obstructive pulmonary disease (COPD), and the role of the nurse practitioner (NP) in facilitating optimum inhaler use. Review of the national and international scientific literature. Pharmacologic treatment of COPD patients comprises mainly inhaled medications. Incorrect use of inhalers is very common in these individuals. Some of the consequences of poor inhaler technique include reduced therapeutic dosing, medication adherence, and disease stability, which can lead to increased morbidity, decreased quality of life, and a high burden on the healthcare system. Knowledgeable evaluation and frequent reassessment of inhaler use coupled with education of patients, caregivers, and healthcare professionals can significantly improve the benefits COPD patients derive from inhaled therapy. Patient education is vital for correct use of inhalers and to ensure the effectiveness of inhaled medications. The NP has a critical role in assessing potential barriers to successful learning by the patient and improving inhaler technique and medication management. The NP can also facilitate success with inhaled medications by providing up-to-date inhaler education for other healthcare team members, who may then act as patient educators. ©2011 The Author(s) Journal compilation ©2011 American Academy of Nurse Practitioners.

    Approximately 60% of women who labor receive some form of neuraxial analgesia, but concerns have been raised regarding whether it negatively impacts the labor and delivery process. In this review, we attempt to clarify what has been established as truths, falsities, and uncertainties regarding the effects of this form of pain relief on labor progression, negative and/or positive. Additionally, although the term “epidural” has become synonymous with neuraxial analgesia, we discuss two other techniques, combined spinal-epidural and continuous spinal analgesia, that are gaining popularity, as well as their effects on labor progression.

  18. Intravenous sub-anesthetic ketamine for perioperative analgesia

    Directory of Open Access Journals (Sweden)

    Andrew W Gorlin

    2016-01-01

    Full Text Available Ketamine, an N-methyl-d-aspartate antagonist, blunts central pain sensitization at sub-anesthetic doses (0.3 mg/kg or less and has been studied extensively as an adjunct for perioperative analgesia. At sub-anesthetic doses, ketamine has a minimal physiologic impact though it is associated with a low incidence of mild psychomimetic symptoms as well as nystagmus and double vision. Contraindications to its use do exist and due to ketamine′s metabolism, caution should be exercised in patients with renal or hepatic dysfunction. Sub-anesthetic ketamine improves pain scores and reduces perioperative opioid consumption in a broad range of surgical procedures. In addition, there is evidence that ketamine may be useful in patients with opioid tolerance and for preventing chronic postsurgical pain.

    Directory of Open Access Journals (Sweden)

    Jeson R Doctor

    2014-01-01

    Full Text Available Neurological deficit is an uncommon but catastrophic complication of epidural anesthesia. Epidural hematomas and abscesses are the most common causes of such neurological deficit. We report the case of a patient with renal cell carcinoma with lumbar vertebral metastasis who developed paraplegia after receiving thoracic epidural anesthesia for a nephrectomy. Subsequently, on histo-pathological examination of the laminectomy specimen, the patient was found to have previously undiagnosed thoracic vertebral metastases which led to a thoracic epidural hematoma. In addition, delayed reporting of symptoms of neurological deficit by the patient may have impacted his outcome. Careful pre-operative investigation, consideration to using alternative modalities of analgesia, detailed patient counseling and stringent monitoring of patients receiving central neuraxial blockade is essential to prevent such complications.

    In this study, the use of medications for analgesia and/or sedation for incarcerated inguinal hernia reductions in the emergency department was analyzed. A retrospective chart review was conducted for all patients presenting to a pediatric emergency department with incarcerated inguinal hernia from 2002 to 2005. A total of 99 children presented with incarcerated hernias during the study period. The median age was 11 months. Forty-four percent of children received medication for the procedure, of them 75% received parenteral and 25% oral or intranasal medications. Forty-five percent of children who received medication went through at least 1 hernia reduction attempt initially without medications. More than half the children with incarcerated inguinal hernias did not receive any medication for pain and/or sedation prior to hernia reduction. Guidelines for medication use for children with incarcerated inguinal hernias need to be developed.

    Novel painkillers are urgently needed. The activation of opioid receptors in peripheral inflamed tissue can reduce pain without central adverse effects such as sedation, apnoea, or addiction. Here, we use an unprecedented strategy and report the synthesis and analgesic efficacy of the standard opioid morphine covalently attached to hyperbranched polyglycerol (PG-M) by a cleavable linker. With its high-molecular weight and hydrophilicity, this conjugate is designed to selectively release morphine in injured tissue and to prevent blood-brain barrier permeation. In contrast to conventional morphine, intravenous PG-M exclusively activated peripheral opioid receptors to produce analgesia in inflamed rat paws without major side effects such as sedation or constipation. Concentrations of morphine in the brain, blood, paw tissue, and in vitro confirmed the selective release of morphine in the inflamed milieu. Thus, PG-M may serve as prototype of a peripherally restricted opioid formulation designed to forego central and intestinal side effects.

    Although routine administration of pharmacologic sedation or analgesia during mechanical ventilation in preterm neonates is not recommended, its use in clinical practice remains common. Alpha-2 agonists, mainly clonidine and dexmedetomidine, are used as adjunctive (or alternative) sedative agents alongside opioids and benzodiazepines. Clonidine has not been systematically assessed for use in neonatal sedation during ventilation. To assess whether clonidine administered to term and preterm newborn infants receiving mechanical ventilation reduces morbidity and mortality rates. To compare the intervention versus placebo, no treatment, and dexmedetomidine; and to assess the safety of clonidine infusion for potential harms.To perform subgroup analyses according to gestational age; birth weight; administration method (infusion or bolus therapy); dose, duration, and route of clonidine administration; and pharmacologic sedation as a co-intervention. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 12) in the Cochrane Library, MEDLINE via PubMed (1966 to January 10, 2017), Embase (1980 to January 10, 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to January 10, 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomized controlled trials and quasi-randomized trials. We searched for randomized controlled trials, quasi-randomized controlled trials, and cluster trials comparing clonidine versus placebo, no treatment, or dexmedetomidine administered to term and preterm newborns receiving mechanical ventilation via an endotracheal tube. For the included trial, two review authors independently extracted data (e.g. number of participants, birth weight, gestational age, all-cause death during initial hospitalization, duration of respiratory support, sedation

    The administration of DTPA by inhalation was examined as an emergency medical treatment. In order to estimate the practical dosage to the human, an accurate model of the human air way was connected to a anesthetizer and respiration was simulated. Ca-DTPA, aerosolized by an ultra-sonic nebulizer, was administered by inhalation to the model. For the experiments, the respiratory volume (tidal volume) and the respiration rate was 12 per minute. Irrigation water from the model of larynx and mouth, and the air filter were collected and measured by chelate titration in order to determine the quantity of aerosolized DTPA and the amount deposited on the trachea and lang. The results indicated that the quantity of aerosolized DTPA varied with dilution of the DTPA solution in a ample. It was found that a 3 time dilution was the most practical and that 73 mg of DTPA per minute could be aerosolized. Furthermore, the results indicated that 46% of the aerosolized DTPA was taken in through inhalation and that 26% of DTPA was deposited in the trachea and lung. These results suggest that in practical application in the emergency medical treatment, 15 minutes of inhalation could delivered to approximately 500 mg of DTPA, and 130 mg could be delivered to the trachea and lung. It is considered that these quantity are enough amount to increase the effects of radioactive nuclides from the body, comparing with the recommended dosage for injection administration. (author)

  7. Aerosol lung inhalation scintigraphy in normal subjects

    We previously reported basic and clinical evaluation of aerosol lung inhalation scintigraphy with /sup 99m/Tc-millimicrosphere albumin (milli MISA) and concluded aerosol inhalation scintigraphy with /sup 99m/Tc-milli MISA was useful for routine examination. But central airway deposit of aerosol particles was found in not only the patients with chronic obstructive pulmonary disease (COPD) but also normal subjects. So we performed aerosol inhalation scintigraphy in normal subjects and evaluated their scintigrams. The subjects had normal values of FEVsub(1.0)% (more than 70%) in lung function tests, no abnormal findings in chest X-ray films and no symptoms and signs. The findings of aerosol inhalation scintigrams in them were classified into 3 patterns; type I: homogeneous distribution without central airway deposit, type II: homogeneous distribution with central airway deposit, type III: inhomogeneous distribution. These patterns were compared with lung function tests. There was no significant correlation between type I and type II in lung function tests. Type III was different from type I and type II in inhomogeneous distribution. This finding showed no correlation with %VC, FEVsub(1.0)%, MMF, V radical50 and V radical50/V radical25, but good correlation with V radical25 in a maximum forced expiratory flow-volume curve. Flow-volume curve is one of the sensitive methods in early detection of COPD, so inhomogeneous distribution of type III is considered to be due to small airway dysfunction.

    Although no generally effective treatment for proctalgia fugax is known, inhalation of salbutamol has been reported to shorten pain attacks in isolated cases. We conducted a randomized, double-blind, placebo-controlled, crossover trial of inhaled salbutamol in 18 patients with proctalgia fugax. The clinical effect was evaluated by recording the duration of severe pain and discomfort during acute attacks. In addition, anorectal motility recordings were analyzed for possible changes in anal resting tone, sphincter relaxation during rectal distension and in rectal compliance prior to and following administration of the two test substances. Sixteen patients completed all investigations. Compared to placebo, salbutamol inhalation shortened the duration of severe pain (p = 0.019). The effect was most marked in patients having prolonged attacks. In the asymptomatic state, neither salbutamol nor placebo led to a significant change in anal resting pressure, anal relaxation during rectal distension, or rectal compliance. Salbutamol also did not alter the threshold for rectal sensation. Salbutamol inhalation shortens attacks of severe pain in patients with proctalgia fugax. The mechanism of this effect remains unexplained.

    Full Text Available Mariam Ibrahim, Rahul Verma, Lucila Garcia-ContrerasDepartment of Pharmaceutical Sciences, College of Pharmacy, The University of Oklahoma Health Sciences Center, Oklahoma City, OK, USAAbstract: The pulmonary route of administration has proven to be effective in local and systemic delivery of miscellaneous drugs and biopharmaceuticals to treat pulmonary and non-pulmonary diseases. A successful pulmonary administration requires a harmonic interaction between the drug formulation, the inhaler device, and the patient. However, the biggest single problem that accounts for the lack of desired effect or adverse outcomes is the incorrect use of the device due to lack of training in how to use the device or how to coordinate actuation and aerosol inhalation. This review summarizes the structural and mechanical features of aerosol delivery devices with respect to mechanisms of aerosol generation, their use with different formulations, and their advantages and limitations. A technological update of the current state-of-the-art designs proposed to overcome current challenges of existing devices is also provided.Keywords: pulmonary delivery, asthma, nebulizers, metered dose inhaler, dry powder inhaler

    1991-01-01

    In pediatric intensive care, analgesia and sedation has become increasingly important for newborns as well as prematures in recent years. However, its importance is frequently not well recognized and sedation is confounded with analgesia. In our intensive-care unit (ICU), fentanyl and midazolam have proved to be useful. In newborn and premature infants, fentanyl alone has been sufficient because of its analgesic and sedative action. In a study on 20 newborns and prematures suffering from severe respiratory problems as compared with a historical group that did not receive fentanyl, we could show that in subjects receiving fentanyl, considerably less treatment with sedatives and other analgesics was necessary. Cardiopulmonary tolerance was satisfactory. The highest bilirubin values were reached about 1 day earlier and were slightly higher than those measured in the control group, but oral nutrition could be initiated sooner. In small infants, additional midazolam was given after cardiac surgery. During the first 72 h, we found a correlation between serum levels of midazolam and the depth of sedation; however, after 72 h of medication, the dose had to be raised because of an increase in metabolic clearance. During the concomitant administration of midazolam and fentanyl, significantly less midazolam was needed to achieve appropriate analog-sedation. Prior to the administration of analgesics and sedatives, care should be taken to ensure that circulatory conditions are stable and that there is no hypovolemia, and the drugs must be given slowly during several minutes. Especially in a pediatric ICU, light and noise should be diminished and contact between the parents and the child should be encouraged, even when the child is undergoing mechanical ventilation.

Acute pain control therefore improves the overall quality of life in patients undergoing cesarean section. Pain relief is a fundamental human right, but there is no gold standard for post–cesarean section pain management.Objective: To compare the efficacy of pentazocine and tramadol used in unimodal and multimodal (in combination with piroxicam approach, in the management of post–cesarean section pain.Materials and methods: This study employed a random allocation design to compare the effectiveness of intramuscular pentazocine (60 mg or tramadol (100 mg as single analgesic agent and in combination with daily intramuscular piroxicam 20 mg, for the management of post–cesarean section pain during the immediate 12 hours after surgery. The primary outcome measure was control of postoperative pain, while the secondary outcome measures were the analgesic agent onset of action, duration of action, patient satisfaction, and maternal and neonatal adverse outcomes. Data obtained were entered into a predesigned sheet and analyzed with the Statistical Package for Social Sciences version 17.

    Azodicarbonamide (ADA) is widely used as a blowing agent in the manufacture of expanded foam plastics, as an aging and bleaching agent in flour, and as a bread dough conditioner. Human exposures have been reported during manufacture as well as during use. Groups of male F344/N rats were administered ADA by gavage, by intratracheal instillation, and by inhalation exposure to determine the disposition and modes of excretion of ADA and its metabolites. At 72 hr following gavage, 30% of the administered ADA was absorbed whereas following intratracheal instillation, absorption was 90%. Comparison between groups of rats exposed by inhalation to ADA to achieve body burdens of 24 or 1230 micrograms showed no significant differences in modes or rates of excretion of [ 14 C]ADA equivalents. ADA was readily converted to biurea under physiological conditions and biurea was the only 14 C-labeled compound present in excreta. [ 14 C]ADA equivalents were present in all examined tissues immediately after inhalation exposure, and clearance half-times on the order of 1 day were evident for all tissues investigated. Storage depots for [ 14 C]ADA equivalents were not observed. The rate of buildup of [ 14 C]ADA equivalents in blood was linearly related to the lung content as measured from rats withdrawn at selected times during a 6-hr inhalation exposure at an aerosol concentration of 25 micrograms ADA/liter. In a study extending 102 days after exposure, retention of [ 14 C]ADA equivalents in tissues was described by a two-component negative exponential function. The results from this study indicate that upon inhalation, ADA is rapidly converted to biurea and that biurea is then eliminated rapidly from all tissues with the majority of the elimination via the urine

    Automated bolus delivery has recently been shown to reduce local anesthetic consumption and improve analgesia, compared with continuous infusion, in continuous sciatic and epidural block. However, there are few data on the influence of local anesthetic delivery method on local anesthetic consumption following interscalene blockade. This randomized, double-blind trial was designed to determine whether hourly automated perineural boluses (4 mL) of local anesthesia delivered with patient-controlled pro re nata (PRN, on demand) boluses would result in a reduction in total local anesthesia consumption during continuous interscalene blockade after shoulder surgery compared with continuous perineural infusion (4 mL/h) plus patient-controlled PRN boluses. One hundred one patients undergoing major shoulder surgery under general anesthesia with ultrasound-guided continuous interscalene block were randomly assigned to receive 0.2% ropivacaine via interscalene end-hole catheter either by continuous infusion 4 mL/h (n = 50) or as automated bolus 4 mL/h (n = 51). Both delivery methods were combined with 5 mL PRN boluses of 0.2% ropivacaine with a lockout time of 30 minutes. Postoperative number of PRN boluses, 24- and 48-hour local anesthetic consumption, pain scores, rescue analgesia (morphine), and adverse events were recorded. There were no significant differences in either the number of PRN ropivacaine boluses or total 48 hour local anesthetic consumption between the groups (18.5 [11-25.2] PRN boluses in the continuous infusion group vs 17 [8.5-29] PRN boluses in the automated bolus group). Postoperative pain was similar in both groups; on day 2, the median average pain score was 4 (2-6) in the continuous infusion group versus 3 (2-5) in the automated bolus group (P = 0.54). Nor were any statistically significant intergroup differences observed with respect to morphine rescue, incidence of adverse events, or patient satisfaction.

    Full Text Available Inhalant abuse is the purposeful inhalation of intoxicating gases and vapors for the purpose of achieving an altered mental state. With its propensity for being yet an under-recognized form of substance use, being gateway to hard substances, cross-cultural penetration crossing socioeconomic boundaries, and causing significant morbidity and mortality in early ages, the prevention of inhalant misuse is a highly pertinent issue. This clinical report identifies a newer perspective in the emergence of inhalant abuse initiation. We report a case of an adult female with late onset of inhalant dependence developing at workplace and recommend for greater awareness, prevention, and management of this expanding substance abuse problem.

    The increasing demand for total knee arthroplasty (TKR) and the initiatives to reduce health care spending have put the responsibility for efficient care on hospitals and providers. Multidisciplinary care pathways have been shown to shorten length of stay and result in improved short-term outcomes. However, common problems such as post-op nausea, orthostasis, and quad weakness remain, while reliance on discharge to rehabilitation facilities may also prolong hospital stay. Our aim was to document that combined modifications of our traditional clinical pathway for unilateral TKR could lead to improved short-term outcomes. We pose the following research questions. Can pathway modifications which include intra-articular infusion and saphenous nerve block (SNB) provide adequate pain relief and eliminate common side effects promoting earlier mobilization? Can planning for discharge to home avoid in-patient rehab stays? Can these combined modifications decrease length of stay even in patients with complex comorbidities indicated by higher ASA class? Will discharge to home incur an increase in complications or a failure to achieve knee range of motion? A retrospective review was performed and identified two cohorts. Group A included 116 patients that underwent unilateral TKR for osteoarthritis between August 2009 and August 2010. Group B included 171 patients that underwent unilateral TKR for osteoarthritis between February 2012 to February 2013. Group A patients were treated with spinal anesthesia with patient-controlled epidural analgesia (PCEA)/femoral nerve block (FNB) for the first 48 h after surgery. Discharge planning was initiated after admission. Group B had spinal anesthesia with SNB and received a continuous intra-articular infusion of 0.2% ropivicaine for 48 h post-op. Discharge planning was initiated with a case manager prior to hospitalization and discharge to home was declared the preferred approach. An intensive home PT program was made available through

    Full Text Available PURPOSE: To compare analgesia traditionally used for thoracic sympathectomy to intrapleural ropivacaine injection in two different doses. METHODS: Twenty-four patients were divided into three similar groups, and all of them received intravenous dipyrone. Group A received intravenous tramadol and intrapleural injection of saline solution. Group B received intrapleural injection of 0.33% ropivacaine, and Group C 0.5% ropivacaine. The following aspects were analyzed: inspiratory capacity, respiratory rate and pain. Pain was evaluated in the immediate postoperative period by means of the visual analog scale and over a one-week period. RESULTS: In Groups A and B, reduced inspiratory capacity was observed in the postoperative period. In the first postoperative 12 hours, only 12.5% of the patients in Groups B and C showed intense pain as compared to 25% in Group A. In the subsequent week, only one patient in Group A showed mild pain while the remainder reported intense pain. In Group B, half of the patients showed intense pain, and in Group C, only one presented intense pain. CONCLUSION: Intrapleural analgesia with ropivacaine resulted in less pain in the late postoperative period with better analgesic outcomes in higher doses, providing a better ventilatory pattern.OBJETIVO: Comparar a analgesia tradicionalmente utilizada para simpatectomia videotoracoscópica à injeção intrapleural de ropivacaína em duas doses diferentes. MÉTODOS: Vinte e quatro pacientes foram distribuídos em três grupos semelhantes, e todos eles receberam dipirona endovenosa. O grupo A recebeu tramadol endovenoso e injeção intrapleural de solução salina. O grupo B recebeu injeção intrapleural de ropivacaína a 0,33%, e Grupo C ropivacaína a 0,5%.

    To analyze the benefits of external cephalic version (ECV) with epidural analgesia at term and labor induction just after the procedure. This is a retrospective observational study with patients who did not want trying a breech vaginal delivery and decided trying an ECV with epidural analgesia at term and wanted labor induction or cesarean section after the procedure. We present the results of 40 ECV with epidural analgesia at term and labor induction or cesarean section just after the ECV. ECV succeeded in 26 out of 40 (65%) patients. Among the 26 successful ECV, 6 delivered by cesarean (23.1%). 20 patients delivered vaginally (76.9%; 50% of all patients). Considering that a high number of cesarean deliveries can be avoided, induction of labor after ECV with epidural analgesia at term can be considered after being discussed in selected patient.

    Prolactin, ACTH, cortisol and HGH levels have been studied on 30 pregnant women in three different periods: during the labour, at the delivery and 24 hours later. They were divided into 3 groups depending on the analgesia: I) no analgesia (n = 10); II) psychoprophylaxis (n = 10), and III) extradural analgesia (n = 10). Prolactin levels increased during delivery and 24 hours later. A significant increase of ACTH levels (p less than 0.01) was observed during the delivery in the 3 groups even though they were under hasal values 24 hours later. Cortisol increased 38% (p less than 0.01) and 52% (p less than 0.02) in II and III groups, respectively during the delivery. No difference was found with HGH. Our results suggest that endocrine response modified by labour and delivery doesn't change with different analgesia techniques.

    Conclusion: The ideal analgesic, offering optimal pain control, minimal side effects, and cost-effectiveness is still elusive. Opioids administered using various techniques, provide effective analgesia, but require active monitoring of patient for potential adverse effects. Combination therapy (oral NSAID and occlusive dressing of EMLA, DMSO with lidocaine offers an effective alternative mode for achieving analgesia with minimal morbidity. This therapy avoids the need for general anesthesia, injectable analgesics, and opioids along with their side effects.

For analgesia after lower abdominal surgery, epidural analgesia and ultrasound-guided transversus abdominis plane (TAP) block are suitable options. The study aims to compare the analgesic efficacy of both techniques. Seventy-two patients undergoing lower abdominal surgery under spinal anesthesia were randomized to postoperatively receive lumbar epidural catheter (Group E) or ultrasound-guided TAP block (Group T) through intravenous cannulas placed bilaterally. Group E received 10 ml 0.125% bupivacaine stat and 10 ml 8 th hourly for 48 h. Group T received 20 ml 0.125% bupivacaine bilaterally stat and 20 ml bilaterally 8 th hourly for 48 h. Pain at rest and on coughing, total paracetamol and tramadol consumption were recorded. Analgesia at rest was comparable between the groups in the first 16 h. At 24 and 48 h, Group E had significantly better analgesia at rest ( P = 0.001 and 0.004 respectively). Patients in Group E had significantly higher number of patients with nil or mild pain on coughing at all times. Paracetamol consumption was comparable in both groups, but tramadol consumption was significantly higher in Group T at the end of 48 h ( P = 0.001). For lower abdominal surgeries, analgesia provided by intermittent boluses of 0.125% is comparable for first 16 h between epidural and TAP catheters. However, the quality of analgesia provided by the epidural catheter is superior to that provided by TAP catheters beyond that both at rest and on coughing with reduced opioid consumption.

    Some anesthesiologists contend that intrathecal opioid administration has advantages over conventional epidural techniques during labor. Randomized clinical trials comparing analgesia and obstetric outcome using single-injection intrathecal opioids versus epidural local anesthetics suggest that intrathecal opioids provide comparable analgesia with few serious side effects. This meta-analysis compared the analgesic efficacy, side effects, and obstetric outcome of single-injection intrathecal opioid techniques versus epidural local anesthetics in laboring women. Relevant clinical studies were identified using electronic and manual searches of the literature covering the period from 1989 to 2000. Searches used the following descriptors: intrathecal analgesia, spinal opioids, epidural analgesia, epidural local anesthetics, and analgesia for labor. Data were extracted from 7 randomized clinical trials comparing analgesic measures, incidence of motor block, pruritus, nausea, hypotension, mode of delivery, and/or Apgar scores. Combined test results indicated comparable analgesic efficacy 15 to 20 minutes after injection with single-injection intrathecal opioid administration. Intrathecal opioid injections were associated with a greater incidence of pruritus (odds ratio, 14.01; 99% confidence interval, 6.9 to 28.3), but there was no difference in the incidence of nausea or in the method of delivery. Published studies suggest that intrathecal opioids provide comparable early labor analgesia when compared with epidural local anesthetics. Intrathecal opioid administration results in a greater incidence of pruritus. The choice of technique does not appear to affect the method of delivery.

    To compare isoflurane, sevoflurane and desflurane for inhalant anesthesia in red-tailed hawks (Buteo jamaicensis) in terms of the speed and characteristics of induction; cardiovascular and respiratory parameters while anesthetized; and speed and quality of recovery. Prospective, cross over, randomized experimental study. 12 healthy adult red-tailed hawks. Anesthesia was induced with isoflurane, sevoflurane or desflurane in oxygen via face mask in a crossover, randomized design with a 1 week washout period between each treatment. Hawks were tracheally intubated, allowed to breathe spontaneously, and instrumented for cardiopulmonary monitoring. Data collected included heart rate, respiratory rate, end-tidal CO(2) , inspired and expired agent, SpO(2,) temperature, systolic blood pressure, time to intubation and time to recovery (tracking). Recovery was subjectively scored on a 4 point scale as well as a summary evaluation, by a single blinded observer. No significant difference in time to induction and time to extubation was noted with the administration of isoflurane, sevoflurane or desflurane. Time to the ability of the bird to follow a moving object with its eyes (tracking) was significantly faster with the administration of sevoflurane and desflurane. All recoveries were scored 1 or 2 and were assessed as good to excellent. No significant difference was noted in heart rate, blood pressure and temperature among the three inhalants. Administration of isoflurane resulted in lower respiratory rates. Overall, although isoflurane remains the most common inhaled anesthetic in avian practice, sevoflurane and desflurane both offer faster time to tracking, while similar changes in cardiopulmonary function were observed with each agent during anesthesia of healthy red-tailed hawks. © 2011 The Authors.

    Full Text Available It is known that pharyngalgia is very common after tonsillectomy. It should be emphasized that the intensity of pain after adenoidectomy in children is not less important than after adenotonsillectomy. Despite the availability of standardized pain assessment scales and existing postoperative analgesia recommendations, unresolved postoperative pain still occurs in children. The research included 117 children with an average age of 7.5 ± 0.4 years, who underwent adenoidectomy at the Department of Anesthesiology and Intensive Care of "Regional Children’s Clinical Hospital" of Kharkov city in 2014. Depending on the method of general anesthesia, patients were divided into 3 groups: group I (n = 41 those who received propofol in combination with fentanyl; group II (n = 40 those who received sevoflurane in combination with fentanyl; group III (n = 36 those who received thiopental sodium combined with fentanyl. We monitored the heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, BIS-index, heart rate variability, respiration rate, and SpO2. We determined the levels of cortisol and insulin in the blood serum, glucose level, the ratio of cortisol/insulin was calculated. Assessment of the efficiency of postoperative analgesia was performed using the Wong-Baker FACES Pain Scale («Faces» and the Oucher Scale. The result of analysis of the intensity of postoperative pain determined that at the 1st hour after the operation by the «Faces» and Oucher scales, it was significantly higher in patients of group II compared with the patients of group I and group III. The morning after the operation there was no significant difference in the pain scales, and the number of scale points showed that children from all groups did not have pain. According to the data of ANOVA it was determined that only the patients in group I with indicator ΔBIS-index «intubation – traumatic moment of operation» experienced postoperative pain

    Full Text Available Scientific knowledge has advanced to enable the development of inhaled insulin. It is a form of diabetes medication administered via the pulmonary system that studies have shown to be efficacious in the treatment of both type 1 and type 2 diabetes. Inhaled insulin is a new, safe means to deliver insulin that may increase patient compliance with insulin therapy, helping them to achieve optimal glycemic control and possibly reducing their risk of developing cardiovascular complications. However, diabetes is a chronic illness requiring lifetime intervention. Empowering patients with the knowledge of the diabetes disease process may give them the confidence to be more autonomous in managing their diabetes. HIIP gives nurse practitioners a new option that may improve their patients’ acceptance of insulin therapy, and improve glycemic control.

The purpose of this study was to evaluate techniques for using inhaler devices in COPD patients.Methods: A prospective cross-sectional study was conducted to assess patient compliance with correct techniques for using inhaler devices across four regimens, ie, the pressurized metered-dose inhaler (pMDI, the pMDI with a spacer, the Accuhaler®, and the Handihaler®. The percentage of compliance with essential steps of correct device usage for each regimen was recorded without prior notification when COPD patients presented for a routine visit, and 1 month after receiving face-to-face training. We compared the percentage of compliance between the devices and risk factors related to incorrect techniques using logistic regression analysis. Percentage of patient compliance with correct techniques was compared between the two visits using the chi-square test. Statistical significance was set at P<0.05.Results: A total of 103 COPD patients (mean age 71.2±9.2 years, males 64.1%, low education level 82.5%, and percent predicted forced expiratory volume in 1 second 51.9±22.5 were evaluated. Seventy-seven patients (74.8% performed at least one step incorrectly. Patients using the Handihaler had the lowest compliance failure (42.5%, and the odds ratio for failure with the other devices compared with the Handihaler were 4.6 (95% confidence interval [CI] 1.8–11.8 for the pMDI, 3.1 (95% CI 1.2–8.2 for the pMDI with a spacer, and 2.4 (95% CI 1.1–5.2 for the Accuhaler.

    Medicinal cannabis is an invaluable adjunct therapy for pain relief, nausea, anorexia, and mood modification in cancer patients and is available as cookies or cakes, as sublingual drops, as a vaporized mist, or for smoking. However, as with every herb, various microorganisms are carried on its leaves and flowers which when inhaled could expose the user, in particular immunocompromised patients, to the risk of opportunistic lung infections, primarily from inhaled molds. The objective of this study was to identify the safest way of using medicinal cannabis in immunosuppressed patients by finding the optimal method of sterilization with minimal loss of activity of cannabis. We describe the results of culturing the cannabis herb, three methods of sterilization, and the measured loss of a main cannabinoid compound activity. Systematic sterilization of medicinal cannabis can eliminate the risk of fatal opportunistic infections associated with cannabis among patients at risk.

    Multidrug-resistant organisms are creating a challenge for physicians treating the critically ill. As new antibiotics lag behind the emergence of worsening resistance, intensivists in countries with high rates of extensively drug-resistant bacteria are turning to inhaled antibiotics as adjunctive therapy. These drugs can provide high concentrations of drug in the lung that could not be achieved with intravenous antibiotics without significant systemic toxicity. This article summarizes current evidence describing the use of inhaled antibiotics for the treatment of bacterial ventilator-associated pneumonia and ventilator-associated tracheobronchitis. Preliminary data suggest aerosolized antimicrobials may effectively treat resistant pathogens with high minimum inhibitory concentrations. Copyright © 2017 Elsevier Inc. All rights reserved.

    Primary objective of the contribution was the theoretical prediction of nanoplatelet deposition in the human respiratory tract. Modeling was founded on the hypothetical inhalation of graphene nanoplatelets (GNP) measuring 0.01 and 0.1μm in thickness and adopting a projected area diameter of 1-30μm. Particle uptake was assumed to take place with inhalation flow rates of 250, 500, 750, and 1000cm 3 s -1 , respectively. For an appropriate description of pulmonary particle behavior, transport of GNP in a stochastic lung structure and deposition formulae based on analytical and numerical studies were presupposed. The results obtained from the theoretical approach clearly demonstrate that GNP with a thickness of 0.01μm deposit in the respiratory tract by 20-50%, whereas GNP with a thickness of 0.1μm exhibit a deposition of 20-90%. Larger platelets deposit with higher probability than small ones. Increase of inhalation flow rate is accompanied by decreased deposition in the case of thin GNP, whilst thicker GNP are preferably accumulated in the extrathoracic region. Generation-specific deposition ranges from 0.05 to 7% (0.01μm) and from 0.05 to 9%, with maximum values being obtained in airway generation 20. In proximal airway generations (0-10), deposition is increased with inhalation flow rate, whereas in intermediate to distal generations a reverse effect may be observed. Health consequences of GNP deposition in different lung compartments are subjected to an intense debate. Copyright © 2017. Published by Elsevier GmbH.

    Electrostatics continues to play an important role in pharmaceutical aerosols for inhalation. Despite its ubiquitous nature, the charging process is complex and not well understood. Nonetheless, significant advances in the past few years continue to improve understanding and lead to better control of electrostatics. The purpose of this critical review is to present an overview of the literature, with an emphasis on how electrostatic charge can be useful in improving pulmonary drug delivery.

    Inhaled Ca-DTPA administered to rats in 6 weekly, one-hour treatments of 3 mg/rat did not affect weight gain or life-span compared to Pu burdened animals (78 nCi ILB) or nontreated controls. In addition, the drug did not appear to promote the development of malignant lung tumors and bone tumors in Pu burdened rats although one rat exposed only to Ca-DTPA aerosols did develop a malignant lung tumor. This single lung tumor can not be considered significant although the normal incidence of this lesion is quite low. Inhaled Ca-DTPA therapy administered 20 days after Pu inhalation showed little effect in reducing the lung burden of plutonium. Skeletal deposition was decreased possibly because Ca-DTPA was administered during a time of active translocation of the inhaled Pu when Pu may have been available for chelation in the blood. Inhaled Ca-DTPA therapy did not appear to be beneficial in reducing the number of malignant lung tumors or bone tumors in plutonium burdened rats but on the other hand the chelate did not appear to promote these lesions.

    Dose assessments for the inhalation of artificial radionuclides are presented for all types of contaminated areas at Maralinga and Emu. These enable Committed Effective Dose Equivalent (CEDE), to be estimated by scaling at any area of interest where activity concentrations are known. In the case of Aborigines, these dose are estimated assuming respirable dust loadings of 1 mg/m 3 for adults and 1.5 mg/m 3 for children and infants. Details of the calculations are presented in the appendix. The model of the respiratory system used in this assessment is that described in Interantional Commission on Radiological Protection (ICRP) Publication 30 (ICRP, 1979a). With the exception of Kuli, which is contaminated with uranium, at all other sites it is only the inhalation of plutonium and americium that contributes significantly to the dose, and of these 239 Pu is the largest contributor. Therefore, considering the long half lives of the radionuclides concerned, it appears that the inhalation problems highlighted by this dose assessment will not diminish significantly within any reasonable period of time and hence management strategies must be developed to deal with such problems. 32 refs., 5 tabs., 1 fig

    Full Text Available The management of patients with chronic respiratory diseases affected by difficult to treat infections has become a challenge in clinical practice. Conditions such as cystic fibrosis (CF and non-CF bronchiectasis require extensive treatment strategies to deal with multidrug resistant pathogens that include Pseudomonas aeruginosa, Methicillin-resistant Staphylococcus aureus, Burkholderia species and non-tuberculous Mycobacteria (NTM. These challenges prompted scientists to deliver antimicrobial agents through the pulmonary system by using inhaled, aerosolized or nebulized antibiotics. Subsequent research advances focused on the development of antibiotic agents able to achieve high tissue concentrations capable of reducing the bacterial load of difficult-to-treat organisms in hosts with chronic respiratory conditions. In this review, we focus on the evidence regarding the use of antibiotic therapies administered through the respiratory system via inhalation, nebulization or aerosolization, specifically in patients with chronic respiratory diseases that include CF, non-CF bronchiectasis and NTM. However, further research is required to address the potential benefits, mechanisms of action and applications of inhaled antibiotics for the management of difficult-to-treat infections in patients with chronic respiratory diseases.

  12. Fragrance sensitisers: Is inhalation an allergy risk?

    Basketter, David; Kimber, Ian

    2015-12-01

    It is well established that some fragrance substances have the potential to cause skin sensitisation associated with the development of allergic contact dermatitis (ACD). Fragrances are invariably relatively volatile leading to the consideration that inhalation of fragrances might be a relevant route for either the induction of allergic sensitisation or the elicitation of allergic reactions. Moreover, there has been increasing recognition that allergic sensitisation of the respiratory tract can be induced by topical exposure to certain chemical allergens. Here the central question addressed is whether inhalation exposure to fragrance allergens has the potential to cause skin and/or respiratory sensitisation via the respiratory tract, or elicit allergic symptoms in those already sensitised. In addressing those questions, the underlying immunobiology of skin and respiratory sensitisation to chemicals has been reviewed briefly, and the relevant experimental and clinical evidence considered. The essential mechanistic differences between skin and respiratory allergy appear consistent with other sources of information, including the phenomenon of ACD that can arise from topical exposure to airborne allergens, but in the absence of accompanying respiratory effects. The conclusion is that, in contrast to topical exposure (including topical exposure to airborne material), inhalation of fragrance sensitisers does not represent a health risk with respect to allergy.

    Full Text Available Context: A retrospective observational study conducted to assess transversus abdominis plane (TAP block as a tool for providing multimodal analgesia postoperatively for abdominal surgeries. Aims: The aim is to compare the visual analog scale (VAS of pain and the requirement of rescue analgesia postoperatively in patients undergoing various abdominal surgeries (open and laparoscopic where TAP block was given for postoperative analgesia and was compared with patients who received pain relief according to the institutional protocol. Settings and Design: Retrospective observational study conducted in a tertiary care hospital. Subjects and Methods: Retrospective data from anesthesia records of patients, who underwent abdominal surgeries from January 2016 to December 2016, were analyzed and were divided into two groups. Group A (n = 250 consisted of patients who received the conventional standard postoperative analgesia protocol of the department of anesthesia. Group B (n = 136 consisted of patients who were administered TAP block postsurgery for the postoperative analgesia by the trained anesthesiologist. Primary outcome considered was (i average VAS at 02, 06, 12, and 24 h and (ii average opioid/nonsteroidal anti-inflammatory drug consumption at 24 h postoperatively. Secondary outcome considered was time to first rescue analgesia. Statistical Analysis: All parametric data were analyzed using unpaired t-test. Data are expressed as the mean ± standard deviation. A SPSS version 17 (SPSS Inc., Chicago, IL, USA was used for statistical analysis. Results: Average pain scores (VAS were lower in Group B as compared to Group A in all subcategories of surgery postoperatively. Patients given TAP block (Group B required less rescue analgesia in the postoperative period with time to first rescue analgesia being prolonged. Conclusions: On the basis of our retrospective study, we suggest that TAP block can be utilized as a part of multimodal analgesia regimen for

    Full Text Available Background. It is well known that the programmed intermittent epidural bolus (PIEB technique effectively provides epidural anesthesia in labor. This randomized double-blind trial compared the postoperative analgesic efficacy of PIEB with that of continuous epidural infusion (CEI in patients undergoing gynecological surgery under combined general-epidural anesthesia. Methods. Patients undergoing open gynecological surgery under combined general-epidural anesthesia were randomized at a 1 : 1 ratio to receive PIEB or CEI. In the PIEB group, the pump delivered 4 mL ropivacaine 0.2% plus fentanyl 2 μg/mL every hour. In the CEI group, the pump delivered the same solution at a rate of 4 mL/h. In both groups, additional 4 mL boluses of ropivacaine 0.2% plus fentanyl 2 μg/mL were provided, when necessary, by patient-controlled epidural analgesia after surgery. The primary outcome was the total ropivacaine dose 40 hours after surgery. The secondary outcomes were the number of PCEA boluses and postoperative pain (evaluated on an 11-point numerical rating scale 3, 24, and 48 hours after surgery. Results. In total, 57 patients were randomized (n=28 and 29 in the PIEB and CEI groups, resp.. The two groups differ significantly in terms of the total ropivacaine dose 40 hours after surgery (mean (standard deviation: 155.38 (4.55 versus 159.73 (7.87 mL, P=0.016. Compared to the CEI group, the PIEB group had significantly lower numerical rating scale scores 3 hours (median [lower–upper quartiles]: 0 [0–0.5] versus 3 [0–5.5], P=0.002, 24 hours (1 [0–2] versus 3 [1–4], P=0.003, and 48 hours (1 [0–2] versus 2 [2–3.5], P=0.002 after surgery. Conclusion. PIEB was better than CEI in terms of providing postoperative analgesia after open gynecological surgery under combined general-epidural anesthesia.

    Inhalation is the most likely exposure route for individuals working with aerosolizable engineered nano-materials (ENM). To properly perform nanoparticle inhalation toxicology studies, the aerosols in a chamber housing the experimental animals must have: 1) a steady concentration maintained at a desired level for the entire exposure period; 2) a homogenous composition free of contaminants; and 3) a stable size distribution with a geometric mean diameter generation of aerosols containing nanoparticles is quite challenging because nanoparticles easily agglomerate. This is largely due to very strong inter-particle forces and the formation of large fractal structures in tens or hundreds of microns in size (6), which are difficult to be broken up. Several common aerosol generators, including nebulizers, fluidized beds, Venturi aspirators and the Wright dust feed, were tested; however, none were able to produce nanoparticle aerosols which satisfy all criteria (5). A whole-body nanoparticle aerosol inhalation exposure system was fabricated, validated and utilized for nano-TiO2 inhalation toxicology studies. Critical components: 1) novel nano-TiO2 aerosol generator; 2) 0.5 m(3) whole-body inhalation exposure chamber; and 3) monitor and control system. Nano-TiO2 aerosols generated from bulk dry nano-TiO2 powders (primary diameter of 21 nm, bulk density of 3.8 g/cm(3)) were delivered into the exposure chamber at a flow rate of 90 LPM (10.8 air changes/hr). Particle size distribution and mass concentration profiles were measured continuously with a scanning mobility particle sizer (SMPS), and an electric low pressure impactor (ELPI). The aerosol mass concentration (C) was verified gravimetrically (mg/m(3)). The mass (M) of the collected particles was determined as M = (Mpost-Mpre), where Mpre and Mpost are masses of the filter before and after sampling (mg). The mass concentration was calculated as C = M/(Q*t), where Q is sampling flowrate (m(3)/min), and t is the sampling

    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 In daily life, dental treatments are often related with oral pain sensation which needs anesthesia procedures. Sometimes local anesthetics can not be used because patients have hypersensitive reaction or systemic diseases which may lead to complications. Stimulating acupoint, such as Hegu activates hypothalamus and pituitary gland to release endogenous opioid peptide substances that reduce pain sensitivity. The aim of the study was to determine Hegu acupoint stimulation effect on the pain sensitivity reduction in maxillary central incisor gingiva. The laboratory experimental research was conducted on 12 healthy male Wistar rats (3 months old, weights 150–200 grams. All rat samples received the same treatments and adapted within 1 month. The research was done in pre and post test control group design. 40-Volt electro-stimulation was done once on the maxillary central incisor gingiva prior to the bilateral Hegu acupoint stimulation, then followed by 3 times electro-stimulation with 3 minutes intervals. The pain scores were obtained based on the samples’ contraction in each electro-stimulation. The responses were categorized into 5 pain scores and statistically analyzed using Wilcoxon Test. The results showed that Hegu acupoint stimulation lowered the pain scores significantly (p < 0.05. Hegu acupoint stimulation could reduce the pain sensitivity in maxillary central incisor gingiva. Therefore, the use of acupuncture analgesia in dental pain management can be considered in the future.

    AIM: To present our experience using intravenous sedoanalgesia for percutaneous biliary drainage. MATERIALS AND METHODS: This study comprised 100 patients, all of whom were continuously monitored [electrocardiogram (ECG), blood pressure, pulse oxymetry] and received an initial dose of 2 mg midazolam followed by 0.02 mg fentanyl. Before every anticipated painful procedure, a maintenance dose of 0.01 mg fentanyl was administered. If the procedure continued and the patient became aware, another 1 mg midazolam was given. This was repeated if patients felt pain. A total dose of 0.08 mg fentanyl and 7 mg midazolam was never exceeded. Immediately after the procedure, the nurse was asked to evaluate patients' pain score. The patients were asked 3 h later to complete a visual 10-degree pain score scale. RESULTS: The average dose of fentanyl and midazolam was 0.042 mg (0.03-0.08 mg) and 4.28 mg (2-7 mg), respectively. Only one patient recorded the procedure as painful. The scores given by the attending nurse (1-7 points, mean 2.9) correlated well with those given by the patients (1-6 points, mean 2.72). No complications were noted. CONCLUSION: According to our experience, interventional radiologists practising biliary procedures can administer low doses of midazolam and minimize the doses of fentanyl, without loss of adequate sedation and analgesia.

    Full Text Available We report a case of thoracic trauma (rib fractures with pneumothorax and pulmonary contusions with severe chest pain leading to ineffective ventilation and oxygenation. The patient presented to our emergency department. The patient had chronic obstructive pulmonary disease and was completely unable to take deep breaths and clear secretions from his bronchial tree. After obtaining informed consent, we applied auricular acupuncture to ameliorate pain and hopefully improve his functional ability to cough and breathe deeply. Within a few minutes, his pain scores diminished considerably, and his ventilation and oxygenation indices improved to safe limits. Auricular acupuncture analgesia lasted for several hours. Parallel to pain reduction, hemodynamic disturbances and anxiety significantly resolved. A second treatment nearly a day later resulted in almost complete resolution of pain that lasted at least 5 days and permitted adequate ventilation, restored oxygenation, and some degree of mobilization (although restricted due to a compression fracture of a lumbar vertebra. Nonopioid and opioid analgesics were sparsely used in low doses during the entire hospitalization period. Hemodynamic alterations and anxiety also decreased, and the patient was soon ready to be discharged.

    Full Text Available Purpose. Transversus abdominis plane (TAP blocks have been shown to reduce pain and opioid requirements after abdominal surgery. The aim of the present case series was to demonstrate the use of TAP catheter injections of bupivacaine after major abdominal surgery. Methods. Fifteen patients scheduled for open colonic resection surgery were included. After induction of anesthesia, bilateral TAP catheters were placed, and all patients received a bolus dose of 20 mL bupivacaine 2.5 mg/mL with epinephrine 5 μg/mL through each catheter. Additional bolus doses were injected bilaterally 12, 24, and 36 hrs after the first injections. Supplemental pain treatment consisted of paracetamol, ibuprofen, and gabapentin. Intravenous morphine was used as rescue analgesic. Postoperative pain was rated on a numeric rating scale (NRS, 0–10 at regular predefined intervals after surgery, and consumption of intravenous morphine was recorded. Results. The TAP catheters were placed without any technical difficulties. NRS scores were ≤3 at rest and ≤5 during cough at 4, 8, 12, 18, 24, and 36 hrs after surgery. Cumulative consumption of intravenous morphine was 28 (23–48 mg (median, IQR within the first 48 postoperative hours. Conclusion. TAP catheter bolus injections can be used to prolong analgesia after major abdominal surgery.

    Preclinical studies demonstrate that cannabinoid-mediated antinociceptive effects vary according to sex; it is unknown if these findings extend to humans. This retrospective analysis compared the analgesic, subjective and physiological effects of active cannabis (3.56-5.60% THC) and inactive cannabis (0.00% THC) in male (N=21) and female (N=21) cannabis smokers under double-blind, placebo-controlled conditions. Pain response was measured using the Cold-Pressor Test (CPT). Participants immersed their hand in cold water (4°C); times to report pain (pain sensitivity) and withdraw the hand (pain tolerance) were recorded. Subjective drug ratings were also measured. Among men, active cannabis significantly decreased pain sensitivity relative to inactive cannabis (pcannabis failed to decrease pain sensitivity relative to inactive. Active cannabis increased pain tolerance in both men women immediately after smoking (pcannabis also increased subjective ratings of cannabis associated with abuse liability ('Take again,' 'Liking,' 'Good drug effect'), drug strength, and 'High' relative to inactive in both men and women (pcannabis smokers, men exhibit greater cannabis-induced analgesia relative to women. These sex-dependent differences are independent of cannabis-elicited subjective effects associated with abuse-liability, which were consistent between men and women. As such, sex-dependent differences in cannabis's analgesic effects are an important consideration that warrants further investigation when considering the potential therapeutic effects of cannabinoids for pain relief.

    AIM: To present our experience using intravenous sedoanalgesia for percutaneous biliary drainage. MATERIALS AND METHODS: This study comprised 100 patients, all of whom were continuously monitored [electrocardiogram (ECG), blood pressure, pulse oxymetry] and received an initial dose of 2 mg midazolam followed by 0.02 mg fentanyl. Before every anticipated painful procedure, a maintenance dose of 0.01 mg fentanyl was administered. If the procedure continued and the patient became aware, another 1 mg midazolam was given. This was repeated if patients felt pain. A total dose of 0.08 mg fentanyl and 7 mg midazolam was never exceeded. Immediately after the procedure, the nurse was asked to evaluate patients' pain score. The patients were asked 3 h later to complete a visual 10-degree pain score scale. RESULTS: The average dose of fentanyl and midazolam was 0.042 mg (0.03-0.08 mg) and 4.28 mg (2-7 mg), respectively. Only one patient recorded the procedure as painful. The scores given by the attending nurse (1-7 points, mean 2.9) correlated well with those given by the patients (1-6 points, mean 2.72). No complications were noted. CONCLUSION: According to our experience, interventional radiologists practising biliary procedures can administer low doses of midazolam and minimize the doses of fentanyl, without loss of adequate sedation and analgesia.

    To explore whether epidural analgesia (EA) in labor is independent risk factor for neonatal pyrexia after controlling for intrapartum pyrexia. Retrospective observational study of 480 consecutive term singleton infants born to mothers who received EA in labor (EA group) and 480 term infants delivered to mothers who did not receive EA (NEA group). Mothers in the EA group had significantly higher incidence of intrapartum pyrexia [54/480 (11%) vs. 4/480 (0.8%), OR = 15.1, p neonatal pyrexia [68/480 (14.2%) vs. 15/480 (3.1%), OR = 5.1, p Neonates in the EA group had a median duration of pyrexia of 1 h (maximum 5 h) with a peak temperature within 1 h. Stepwise logistic regression analysis showed that maternal EA was independent risk factor for neonatal pyrexia (>37.5°C) after controlling for intrapartum pyrexia (>37.9°C) and other confounders (OR = 3.44, CI = 1.9-6.3, p neonates. It is unnecessary to investigate febrile offspring of mothers who have had epidurals unless pyrexia persists for longer than 5 h or other signs or risk factors for neonatal sepsis are present.

    Transversus abdominis plane (TAP) blocks have been reported to be an effective method of providing analgesia after abdominal surgery. To perform a prospective audit on the effectiveness of a novel technique of providing continuous transversus abdominis plane (TAP) analgesia in patients undergoing emergency and elective abdominal surgery. Prospective single center audit over a 3-year period. University hospital. One hundred twenty-four American Society of Anesthesiologists I to IV adult patients presenting for elective as well as emergency abdominal surgery in whom epidural analgesia was contraindicated or refused. Four quadrant TAP blocks and continuous TAP analgesia. Numerical rating scale pain scores at rest and on coughing, nausea scores, satisfaction scores, complications, frequency of analgesia failure, therapeutic failure with continuous TAP analgesia and opioid consumption. One hundred twenty-four patients who received continuous TAP analgesia were audited. This included 34 patients for elective open surgery, 36 patients for emergency laparotomy, and 54 patients who underwent elective laparoscopic colorectal surgery. Surgical incision was within the dermatomal limit of the block in 70% of the patients (88/124). Therapeutic failure with the technique was 10%. Frequency of analgesic failure over the 48-hour period was none in 39% and below 5 episodes in 57%. Four quadrant transversus abdominis plane blocks and continuous TAP analgesia is an effective technique for providing postoperative analgesia after abdominal surgery. It has the potential to be used as a sole analgesic technique when the surgical incision is within its dermatomal limit. Copyright © 2015 Elsevier Inc. All rights reserved.

  7. Special aspects of pharmacokinetics of inhalation anesthesia.

    2008-01-01

    Recent interest in the use of low-flow or closed circuit anesthesia has rekindled interest in the pharmacokinetics of inhaled anesthetics. The kinetic properties of inhaled anesthetics are most often modeled by physiologic models because of the abundant information that is available on tissue solubilities and organ perfusion. These models are intuitively attractive because they can be easily understood in terms of the underlying anatomy and physiology. The use of classical compartment modeling, on the other hand, allows modeling of data that are routinely available to the anesthesiologist, and eliminates the need to account for every possible confounding factor at each step of the partial pressure cascade of potent inhaled agents. Concepts used to describe IV kinetics can readily be applied to inhaled agents (e.g., context-sensitive half-time and effect site concentrations). The interpretation of the F(A)/F(I) vs time curve is expanded by reintroducing the concept of the general anesthetic equation-the focus is shifted from "how F(A) approaches F(I)" to "what combination of delivered concentration and fresh gas flow (FGF) can be used to attain the desired F(A)." When the desired F(A) is maintained with a FGF that is lower than minute ventilation, rebreathing causes a discrepancy between the concentration delivered by the anesthesia machine (=selected by the anesthesiologist on the vaporizer, F(D)) and that inspired by the patient. This F(D)-F(I) discrepancy may be perceived as "lack of control" and has been the rationale to use a high FGF to ensure the delivered matched the inspired concentration. Also, with low FGF there is larger variability in F(D) because of interpatient variability in uptake. The F(D)-F(I) discrepancy increases with lower FGF because of more rebreathing, and as a consequence the uptake pattern seems to be more reflected in the F(D) required to keep F(A) constant. The clinical implication for the anesthesiologist is that with high FGF few F

    Novel nicotine delivery products, such as electronic cigarettes (e-cigarettes), have dramatically grown in popularity despite limited data on safety and benefit. In contrast, the similar U.S. Food and Drug Administration (FDA)-approved nicotine inhaler is rarely utilized by smokers. Understanding this paradox could be helpful to determine the potential for e-cigarettes as an alternative to tobacco smoking. To compare the e-cigarette with the nicotine inhaler in terms of perceived benefits, harms, appeal, and role in assisting with smoking cessation. A cross-over trial was conducted from 2012 to 2013 PARTICIPANTS/INTERVENTIONS: Forty-one current smokers age 18 and older used the e-cigarette and nicotine inhaler each for 3 days, in random order, with a washout period in between. Thirty-eight participants provided data on product use, perceptions, and experiences. The Modified Cigarette Evaluation Questionnaire (mCEQ) measured satisfaction, reward, and aversion. Subjects were also asked about each product's helpfulness, similarity to cigarettes, acceptability, image, and effectiveness in quitting smoking. Cigarette use was also recorded during the product-use periods. The e-cigarette had a higher total satisfaction score (13.9 vs. 6.8 [p e-cigarette received higher ratings for helpfulness, acceptability, and "coolness." More subjects would use the e-cigarette to make a quit attempt (76 %) than the inhaler (24 %) (p e-cigarette vs. 10 % (4/38) using the inhaler (p = 0.18). The e-cigarette was more acceptable, provided more satisfaction, and had higher perceived benefit than the inhaler during this trial. E-cigarettes have the potential to be important nicotine delivery products owing to their high acceptance and perceived benefit, but more data are needed to evaluate their actual efficacy and safety. Providers should be aware of these issues, as patients will increasingly inquire about them.

    Full Text Available In recent times Inhalant or Volatile substances are emerging as a major drug of abuse in the preadolescent and adolescent age group. Most of the children are from broken homes and poor backgrounds. Inhalants have serious immediate and longterm side-effects and can also cause sudden sniffing death syndrome. It is difficult to control this ever-growing problem because Inhalants or Solvents are widely available. Management issues have been discussed in the review.

  10. Economic considerations in the use of inhaled anesthetic agents.

    2010-04-15

    To describe the components of and factors contributing to the costs of inhaled anesthesia, basis for quantifying and comparing these costs, and practical strategies for performing pharmacoeconomic analyses and reducing the costs of inhaled anesthetic agents. Inhaled anesthesia can be costly, and some of the variable costs, including fresh gas flow rates and vaporizer settings, are potential targets for cost savings. The use of a low fresh gas flow rate maximizes rebreathing of exhaled anesthetic gas and is less costly than a high flow rate, but it provides less control of the level of anesthesia. The minimum alveolar concentration (MAC) hour is a measure that can be used to compare the cost of inhaled anesthetic agents at various fresh gas flow rates. Anesthesia records provide a sense of patterns of inhaled anesthetic agent use, but the amount of detail can be limited. Cost savings have resulted from efforts to reduce the direct costs of inhaled anesthetic agents, but reductions in indirect costs through shortened times to patient recovery and discharge following the judicious use of these agents are more difficult to demonstrate. The patient case mix, fresh gas flow rates typically used during inhaled anesthesia, availability and location of vaporizers, and anesthesia care provider preferences and practices should be taken into consideration in pharmacoeconomic evaluations and recommendations for controlling the costs of inhaled anesthesia. Understanding factors that contribute to the costs of inhaled anesthesia and considering those factors in pharmacoeconomic analyses and recommendations for use of these agents can result in cost savings.

    Full Text Available The paper deals with the economical and ecological use of inhalation anesthetics in low-flow anesthesia (LFA, 1—0.5 l/ min and high-flow anesthesia (HFA, more than 2—6 l/min. Four hundred and ninety six inhalational anesthesias lasting at least 80 minutes were analyzed in each group under consideration. The concentration of inhalation anesthetics was measures in the atmosphere of an operative theatre if inhalational anesthesia lasted more than 4 hours. There is evidence for the economical and ecological benefits in the use of LFA in terms of the availability of appropriate anesthesiological equipment, monitoring, and a highly skilled anesthesiologist.

    The role played by central 5-hydroxytryptamine (5-HT) in electroacupuncture analgesia has been studied in rats by means of autoradiography with isotopic tracers 3 H-5-HT. The purpose of the study is to determine the localization of 3 H-5-HT in the midbrain raphe nuclei and in the mesencephalon aquaeduct as well as periaquaeductal gray matter. Parallel experiments were studied by freezing microautoradiographic method and histo-fixative microautoradiographic method. The analgesic effect of acupuncture can be enhanced or lowered by the increment or the decrement of the 5-HT level in the midbrain raphe nuclei and in the mesencephalon aquaeduct as well as periaquaeductal gray matter. The results show that when the rats were subjected to electro-acupuncture analgesia, the microautoradiographic intensities of 3 H-5-HT both in the midbrain raphe nuclei and in the areas of mesencephalon aqueduct were significantly increased. It may be observed that the release of 5-HT in these regions of the brain is accelerated during acupuncture analgesia. From this it can be concluded that the midbrain raphe nuclei and the mesencephalon aquaeduct as well as the periaquaeductal gray matter are closely related to acupuncture analgesia. The results imply that 5-HT in these areas may be one of the most important neurochemical agents mediating acupuncture analgesia

    Multimodal analgesia is promoted as the best practice pain management for invasive animal research procedures. Universal acceptance and incorporation of multimodal analgesia requires assessing potential effects on study outcome. The focus of this study was to assess effects on embryo survival after multimodal analgesia comprising an opioid and nonsteroidal antiinflammatory drug (NSAID) compared with opioid-only analgesia during embryo transfer procedures in transgenic mouse production. Mice were assigned to receive either carprofen (5 mg/kg) with buprenorphine (0.1 mg/kg; CB) or vehicle with buprenorphine (0.1 mg/kg; VB) in a prospective, double-blinded placebo controlled clinical trial. Data were analyzed in surgical sets of 1 to 3 female mice receiving embryos chimeric for a shared targeted embryonic stem-cell clone and host blastocyst cells. A total of 99 surgical sets were analyzed, comprising 199 Crl:CD1 female mice and their 996 offspring. Neither yield (pups weaned per embryo implanted in the surgical set) nor birth rate (average number of pups weaned per dam in the set) differed significantly between the CB and VB conditions. Multimodal opioid–NSAID analgesia appears to have no significant positive or negative effect on the success of producing novel lines of transgenic mice by blastocyst transfer. PMID:21838973

    The objective is to study the effects of flurbiprofen axetil (FA) with fentanyl together in postoperative controlled intravenous analgesia (PCIA) on pain intensity, cytokine levels in peripheral blood and adverse reactions of thoracotomy patients. Fifty thoracotomy patients were divided into a FA and a control group, each with 25 cases. Postoperative analgesia was administered in the two groups using PCIA. The pressing times of analgesia pump, the visual analog scale (VAS) scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery and the incidence of adverse drug reactions were recorded. Levels of IL-1β, IL-6, IL-8, IL-2, and TNF-α in peripheral blood were determined before the administration of FA (T0), and at 24 h (T1), 48 h (T2), 72 h (T3) after surgery. The analgesia pump pressing times in the FA group was less than that of the control group. The VAS scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery, were statistically less than those of control group. The incidence rate of nausea and vomiting was insignificantly different between the two groups. Administration of FA together with PCIA in thoracotomy patients can improve postoperative analgesia.

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: Combined spinal-epidural (CSE has become an increasingly popular alternative to traditional labour epidural due to its rapid onset and reliable analgesia provided. This was a prospective, convenient sampling study to determine the effects of CSE analgesia on labour outcome. METHODS: One hundred and ten healthy primigravida parturients with a singleton pregnancy of ≥37 weeks gestation and in the active phase of labour were studied. They were enrolled to the CSE (n = 55 or Non-CSE (n = 55 group based on whether they consented to CSE analgesia. Non-CSE parturients were offered other methods of labour analgesia. The duration of the first and second stage of labour, rate of instrumental vaginal delivery and emergency cesarean section, and Apgar scores were compared. RESULTS: The mean duration of the first and second stage of labour was not significantly different between both groups. Instrumental delivery rates between the groups were not significantly different (CSE group, 11% versus Non-CSE group, 16%. The slightly higher incidence of cesarean section in the CSE group (16% versus 15% in the Non-CSE group was not statistically significant. Neonatal outcome in terms of Apgar score of less than 7 at 1 and 5 min was similar in both groups. CONCLUSION: There were no significant differences in the duration of labour, rate of instrumental vaginal delivery and emergency cesarean section, and neonatal outcome in parturients who received compared to those who did not receive CSE for labour analgesia.

    The aim of this retrospective study is to test the hypothesis that the use of spinal analgesia shortens the length of hospital stay after partial nephrectomy. We reviewed all patients undergoing partial nephrectomy for malignancy through flank incision between January 1, 2008, and June 30, 2011. We excluded patients who underwent tumor thrombectomy, used sustained-release opioids, or had general anesthesia supplemented by epidural analgesia. Patients were grouped into "spinal" (intrathecal opioid injection for postoperative analgesia) versus "general anesthetic" group, and "early" discharge group (within 3 postoperative days) versus "late" group. Association between demographics, patient physical status, anesthetic techniques, and surgical complexity and hospital stay were analyzed using multivariable logistic regression analysis. Of 380 patients, 158 (41.6%) were discharged "early" and 151 (39.7%) were "spinal" cases. Both spinal and early discharge groups had better postoperative pain control and used less postoperative systemic opioids. Spinal analgesia was associated with early hospital discharge, odds ratio 1.52, (95% confidence interval 1.00-2.30), P = 0.05, but in adjusted analysis was no longer associated with early discharge, 1.16 (0.73-1.86), P = 0.52. Early discharge was associated with calendar year, with more recent years being associated with early discharge. Spinal analgesia combined with general anesthesia was associated with improved postoperative pain control during the 1(st) postoperative day, but not with shorter hospital stay following partial nephrectomy. Therefore, unaccounted practice changes that occurred during more recent times affected hospital stay.

    our objective was to determine the association between epidural analgesia and different variables. the effect on newborns of epidural analgesia administered to the mother during labour remains under debate. this association was retrospectively investigated in a cohort of 2399 children born in a Spanish public hospital. Only full-term (>37 weeks of gestation) deliveries were included. Other exclusion criteria were: induced delivery (medical or obstetric indication), elective caesarean section, or the presence of an important pregnancy risk factors (hypertension, diabetes, severe disease, toxaemia, retarded intrauterine growth, chronologically prolonged pregnancy, prolonged membrane rupture (>24 hours), oligoamnios, or polyhydramnios). The Mann-Whitney U test and Fisher׳s exact test were applied to determine the relationship between variables. Apgar index values at one minute and five minutes were slightly but significantly lower in neonates whose mothers had received epidural analgesia. Neonatal intensive care unit admission was significantly more frequent in the epidural versus non-epidural group. Resuscitation was significantly more frequent in the epidural versus non-epidural group. Early breast feeding onset was more frequent in the non-epidural group. The adverse effect of epidural analgesia on early lactation remained significant after adjusting for NICU admission and the need for resuscitation in a logistic regression analysis. Epidural analgesia may have adverse effects on newborns, although the risks are low, and further research is required to elucidate the causal nature of this relationship.

    Piedrahíta-Gutiérrez, Dany Leandro

    2016-07-01

    Full Text Available Objective: To describe and compare the obstetric and perinatal outcomes in patients with or without obstetric analgesia during labor, and to determine whether such analgesia is associated with adverse maternal or perinatal outcomes. Methodology: Comparative, retrospective, descriptive study, between January and November 2014, that included 502 healthy patients with normal pregnancies, out of which 250 received obstetric analgesia. The groups were compared as to maternal and perinatal outcomes. Results: Young, single and nulliparous mothers predominated; delivery was vaginal in 86 % of the cases, and by caesarean section in 14 %. Obstetric analgesia was associated with longer duration of the second stage of labor, instrumental delivery and cesarean section due to arrest of dilatation or fetal bradycardia; however, it was not related with higher incidence of postpartum hemorrhage or adverse perinatal outcomes such as meconium-stained amniotic fluid, Apgar under 5 at one minute or under 7 at 5 minutes, the need for neonatal resuscitation or for admission to NICU. Conclusion: Obstetric analgesia increases the duration of the second stage of labor and can increase the rate of caesarean sections and instrumental delivery, but it is not associated with adverse maternal or perinatal outcomes. Therefore, its use in labor is justified.

This study was planned to evaluate whether dural puncture improves onset and duration of labor analgesia when compared to conventional epidural technique.Methods and Materials: Sixty term primigravida parturients of ASA grade I and II were randomly assigned to two groups of 30 each (Group E for conventional epidural and Group DE for dural puncture epidural. In group E, epidural space was identified and 18-gauge multi-orifice catheter was threaded 5 cm into the epidural space. In group DE, dura was punctured using the combines spinal epidural (CSE spinal needle and epidural catheter threaded as in group E followed by 10 ml of injection of Ropivacaine (0.2% with 20 mcg of Fentanyl (2 mcg/ml in fractions of 2.5 ml. Later, Ropivacaine 10 ml was given as a top-up on patient request. Onset, visual analouge scale (VAS, sensory and motor block, haemodynamic variables, duration of analgesia of initial dose were noted along with mode of delivery and the neonatal outcome.Results: Six parturients in group DE achieved adequate analgesia in 5 minutes while none of those in group E (P 0.05.Conclusions: Both techniques of labor analgesia are efficacious; dural puncture epidural has the potential to fasten onset and improve quality of labor analgesia when compared with conventional epidural technique.

    Bronchiectasis is a chronic inflammatory disease characterised by a recurrent cycle of respiratory bacterial infections associated with cough, sputum production and impaired quality of life. Antibiotics are the main therapeutic option for managing bronchiectasis exacerbations. Evidence suggests that inhaled antibiotics may be associated with more effective eradication of infective organisms and a lower risk of developing antibiotic resistance when compared with orally administered antibiotics. However, it is currently unclear whether antibiotics are more effective when administered orally or by inhalation. To determine the comparative efficacy and safety of oral versus inhaled antibiotics in the treatment of adults and children with bronchiectasis. We identified studies through searches of the Cochrane Airways Group's Specialised Register (CAGR), which is maintained by the Information Specialist for the group. The Register contains trial reports identified through systematic searches of bibliographic databases including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, AMED, and PsycINFO, and handsearching of respiratory journals and meeting abstracts. We also searched ClinicalTrials.gov and the WHO trials portal. We searched all databases in March 2018 and imposed no restrictions on language of publication. We planned to include studies which compared oral antibiotics with inhaled antibiotics. We would have considered short-term use (less than four weeks) for treating acute exacerbations separately from longer-term use as a prophylactic (4 weeks or more). We would have considered both intraclass and interclass comparisons. We planned to exclude studies if the participants received continuous or high-dose antibiotics immediately before the start of the trial, or if they have received a diagnosis of cystic fibrosis (CF), sarcoidosis, active allergic bronchopulmonary aspergillosis or active non-tuberculous Mycobacterial infection

    Despite their prevalence in the environment, and the myriad studies that have shown associations between morbidity or mortality with proximity to roadways (proxy for motor vehicle exposures), relatively little is known about the toxicity of gasoline engine emissions (GEE). We review the studies conducted on GEE to date, and summarize the findings from each of these studies. While there have been several studies, most of the studies were conducted prior to 1980 and thus were not conducted with contemporary engines, fuels, and driving cycles. In addition, many of the biological assays conducted during those studies did not include many of the assays that are conducted on contemporary inhalation exposures to air pollutants, including cardiovascular responses and others. None of the exposures from these earlier studies were characterized at the level of detail that would be considered adequate today. A recent GEE study was conducted as part of the National Environmental Respiratory Center (www.nercenter.org). In this study several in-use mid-mileage General Motors (Chevrolet S-10) vehicles were purchased and utilized for inhalation exposures. An exposure protocol was developed where engines were operated with a repeating California Unified Driving Cycle with one cold start per day. Two separate engines were used to provide two cold starts over a 6-h inhalation period. The exposure atmospheres were characterized in detail, including detailed chemical and physical analysis of the gas, vapor, and particle phase. Multiple rodent biological models were studied, including general toxicity and inflammation (e.g., serum chemistry, lung lavage cell counts/differentials, cytokine/chemokine analysis, histopathology), asthma (adult and in utero exposures with pulmonary function and biochemical analysis), cardiovascular effects (biochemical and electrocardiograph changes in susceptible rodent models), and susceptibility to infection (Pseudomonas bacteria challenge). GEE resulted in

  2. Lung dosimetry for inhaled radon progeny

    Lung cancer risk assessment for inhaled radon progeny requires a detailed knowledge of the dose distribution pattern throughout the human respiratory tract. Current lung dosimetry models take into acocunt aerosol deposition in a formalized airway structrue, modification of the initial deposition pattern by clearance mechanisms, and the energy deposited by alpha particles in sensitive cells of the bronchial epithelium. The resulting dose distribution pattern depends on the characteristics of the inhaled aerosol and the breathing pattern. Special emphasis has been laid on the age dependency of the anatomical structure of the human lung and the resulting doses, as well as on the rediological significance of enhanced aerosol deposition at bronchial bifuraction. The biological variability inherent in all morphometric, physiological and histological parameters involved in lung dosimetry suggests the application of stochastic modelling techniques. Examples for the use of Monte Carlo methods presented here are the random walk of inhaled particles through a random airway geometry, and the influence of the intra-subject variability of radiation doses on radiation protection standards. At the cellular level the concept of absorbed dose loses its significance and has to be replaced by microdosimetric concepts, such as internal microdosimtry or track structure theory. An image-analysis model allows us to construct specific energy distributions in sensitive lung cells. Application of a track structure model of alpha particle interaction with bronchial epithelial cells permits the calculation of probabilities for inactivation, transformation, and tumor induction. The latter has been used to analyse lung cancer risk at low doses in Chinese high background areas

    Full Text Available BACKGROUND To provide postoperative pain relief is a prime duty of health care providers. Failure to relieve pain is morally and ethically unacceptable. Post-operative pain may results in adverse effects such as: a Physiological Changes: Reduced pulmonary functions, e.g. vital capacity, tidal volume, functional residual capacity; sympathetic stimulation; reduced the physical activity of patients; thereby increasing the risk of venous thrombosis. b Psychological disturbances: Anger, Resentment, Depression, Adversarial Relationship with Doctors, Insomnia. Aim of this study was 1. To investigate whether “Postoperative analgesia with Nalbuphine is longer than Pentazocine”. 2. To investigate whether “Side effects/complications are less with Nalbuphine as compared to Pentazocine”. MATERIALS AND METHODS It was a prospective randomized double blind observational study. Eighty patients of hydrocoele & inguinal hernia were operated under spinal anaesthesia of age group 20-70 years, ASA grade I & II & patients with controlled co-morbid conditions. In postoperative period, Group N- Inj. Nalbuphine (0.3 mg/kg IM or Group P- Inj. Pentazocine (0.5 mg/kg IM was administered to provide postoperative pain relief & to know the duration of pain relief & its side effects. RESULTS On statistical analysis, demographic data i.e. age, sex had no influence on outcome of study. Mean VAS score in group N was highly significant (p-value in Inj. Pentazocine group. 2. Side Effects - Incidence of sedation was more in Nalbuphine group as compared to Pentazocine group. Nausea & Vomiting were more so in Pentazocine group as compared to Nalbuphine group. Limitation of the present study was that sample size was very small.

    To assess, in newborn infants submitted to surgical procedures, the efficacy of two opioids-fentanyl and tramadol-regarding time to extubate, time to achieve 100 ml/kg of enteral feeding and pain in the first 72 h after surgery. Controlled, blind, randomised clinical trial. Neonatal intensive care unit. 160 newborn infants up to 28 days of life requiring major or minor surgeries. Patients were randomised to receive analgesia with fentanyl (1-2 μg/kg/h intravenously) or tramadol (0.1-0.2 mg/kg/h intravenously) in the first 72 h of the postoperative period, stratified by surgical size and by patient's gender. Pain assessed by validated neonatal scales (Crying, Requires oxygen, Increased vital signs, Expression and Sleepless Scale and the Neonatal Facial Coding System), time until extubation and time to reach 100 ml/kg enteral feeding. Statistical analysis included repeated measures analysis of variance adjusted for confounding variables and Kaplan-Meier curve adjusted by a Cox model of proportional risks. Neonatal characteristics were (mean±SD) birth weight of 2924±702 g, gestational age of 37.6±2.2 weeks and age at surgery of 199±63 h. The main indication of surgery was gastrointestinal malformation (85 newborns; 53%). Neonates who received fentanyl or tramadol were similar regarding time until extubation, time to reach 100 ml/kg of enteral feeding and pain scores in the first 72 h after surgery. Tramadol was as effective as fentanyl for postoperative pain relief in neonates but does not appear to offer advantages over fentanyl regarding the duration of mechanical ventilation and time to reach full enteral feeding. Trial registration NCT00713726.

    There is no consensus on the most effective pain management for neonatal circumcision. We sought to compare different modalities. This is a double-blinded randomized controlled trial comparing 3 combination analgesics used during circumcision (EMLA + sucrose; EMLA + sucrose + dorsal penile nerve block [DPNB]; EMLA + sucrose + ring block [RB]) with the traditional topical analgesic cream EMLA alone. The trial was set in the normal nursery of a teaching hospital. The sample included 70 healthy male newborns, randomly assigned to intervention and control groups at a 2:1 ratio. Infants were videotaped (face and torso) during the procedure for assessment of pain by 2 blinded, independent reviewers. The primary outcome measure is the Neonatal Infant Pain Scale score. Secondary outcomes include heart rate, oxygen saturation, and crying time. Neonatal Infant Pain Scale scores were significantly lower in the intervention groups (EMLA + sucrose, mean [SD]: 3.1 [1.33]; EMLA + sucrose + DPNB: 3 [1.33]; EMLA + sucrose + RB: 2.45 [1.27]) compared with the control (5.5 [0.53]). Between-group analyses showed RB + EMLA + sucrose to be significantly more effective than EMLA + sucrose; EMLA + sucrose + DPNB ( P = .009 and P = .002, respectively). Interrater reliability was κ = 0.843. Significant increase in heart rate (139.27 [9.63] to 163 [13.23] beats per minute) and crying time (5.78 [6.4] to 45.37 [12.39] seconds) were noted in the EMLA group. During neonatal circumcision in boys, the most effective analgesia is RB combined with oral sucrose and EMLA cream. Copyright © 2017 by the American Academy of Pediatrics.

    To investigate differences in the use of epidural analgesia (EDA) during labor between native Swedish and immigrant women and whether such possible differences could be explained by other maternal factors or birthweight. Population-based register study. Nationwide study in Sweden. A total of 455,274 primiparous women, who gave birth to a singleton infant at 37-41 completed gestational weeks during 1992-2005. Of the 72,086 (16%) immigrants, data on 31,148 women from the eight most common countries of origin were analyzed to test our hypotheses. Register study with perinatal data from the Medical Birth Register and socio-demographic variables from national income and population registers. Use of EDA during vaginal delivery. Compared with native Swedish women, EDA was more often used by women from Chile, odds ratio (OR) 1.39 (95% confidence interval (CI) 1.23-1.57); Iran, OR 1.38 (1.26-1.53); Poland, OR 1.22 (1.08-1.37) and Finland, OR 1.10 (1.03-1.17) after adjustments for perinatal and socio-demographic confounders, while EDA was less often used among women from Somalia, OR 0.57 (0.46-0.70); Iraq, OR 0.71 (0.64-0.78); Turkey, OR 0.77(0.69-0.86) and Yugoslavia, OR 0.85 (0.79-0.91). Having a native Swedish partner increased the use of EDA in immigrant women. EDA use during labor varies more by maternal country of origin than by socio-economic factors. This suggests that expectations of care from the country of origin continue to influence the use of EDA after immigration to Sweden.

    Full Text Available Lung cancer is the leading cause of cancer-related deaths. Traditional chemotherapy causes serious toxicity due to the wide bodily distribution of these drugs. Curcumin is a potential anticancer agent but its low water solubility, poor bioavailability and rapid metabolism significantly limits clinical applications. Here we developed a liposomal curcumin dry powder inhaler (LCD for inhalation treatment of primary lung cancer. LCDs were obtained from curcumin liposomes after freeze-drying. The LCDs had a mass mean aerodynamic diameter of 5.81 μm and a fine particle fraction of 46.71%, suitable for pulmonary delivery. The uptake of curcumin liposomes by human lung cancer A549 cells was markedly greater and faster than that of free curcumin. The high cytotoxicity on A549 cells and the low cytotoxicity of curcumin liposomes on normal human bronchial BEAS-2B epithelial cells yielded a high selection index partly due to increased cell apoptosis. Curcumin powders, LCDs and gemcitabine were directly sprayed into the lungs of rats with lung cancer through the trachea. LCDs showed higher anticancer effects than the other two medications with regard to pathology and the expression of many cancer-related markers including VEGF, malondialdehyde, TNF-α, caspase-3 and BCL-2. LCDs are a promising medication for inhalation treatment of lung cancer with high therapeutic efficiency. Key words: Curcumin, Dry powder inhaler, Liposome, Primary lung cancer, Pulmonary delivery

Optimization of perio-perative analgesia method, then reduce perioperative stress response, reduce opioiddosage, to reduce or even avoid systemic adverse reactions and elevated levels of tumor markers. Serum levels of tumor markers in patients with lung cancer are closely related to tumor growth. Clinical research reports on regional anesthesia effect on tumor markers for lung cancer are still very little in domesticliterature. The aim of this study is to evaluate the effects of thoracic paraverte-bral block on postoperative analgesia and serum level of tumor marker in lung cancer patients undergoing video-assisted thoracoscopic surgery. Methods Lung cancer patients undergoing video-assisted thoracoscopic surgery were randomly divided into 2 groups (n=20 in each group. The patients in group G were given only general anesthesia. The thoracic paravertebral blockade (PVB was performed before general anesthesia in patients of group GP. The effect of PVB was judged by testing area of block.

    To evaluate the feasibility, acceptability and effectiveness of a brief intervention about inhaler technique, delivered by community pharmacists to asthma patients. Thirty-one pharmacists received brief workshop education (Active: n=16, CONTROL: n=15). Active Group pharmacists were trained to assess and teach dry powder inhaler technique, using patient-centered educational tools including novel Inhaler Technique Labels. Interventions were delivered to patients at four visits over 6 months. At baseline, patients (Active: 53, CONTROL: 44) demonstrated poor inhaler technique (mean+/-S.D. score out of 9, 5.7+/-1.6). At 6 months, improvement in inhaler technique score was significantly greater in Active cf. CONTROL patients (2.8+/-1.6 cf. 0.9+/-1.4, p<0.001), and asthma severity was significantly improved (p=0.015). Qualitative responses from patients and pharmacists indicated a high level of satisfaction with the intervention and educational tools, both for their effectiveness and for their impact on the patient-pharmacist relationship. A simple feasible intervention in community pharmacies, incorporating daily reminders via Inhaler Technique Labels on inhalers, can lead to improvement in inhaler technique and asthma outcomes. Brief training modules and simple educational tools, such as Inhaler Technique Labels, can provide a low-cost and sustainable way of changing patient behavior in asthma, using community pharmacists as educators.

Plutonium nitrate was chosen to represent soluble material more readily translocated to bone and other tissues than the oxide. Bone lesions related to plutonium exposure were observed only in dogs exposed to 238 Pu oxide and 239 Pu nitrate. The skeleton accumulated approximately 2% ( 239 Pu oxide), 45% ( 238 Pu oxide) or 50% ( 239 Pu nitrate) of the final body burdens at 13, 10, and 7 years, respectively, after exposure. 11 references, 2 figures

    Consumer aerosol products can be inhaled for their psychoactive effects, but with attendant adverse health effects including "sudden sniffing death." Cardiomyopathy has rarely been described in association with 1,1-difluoroethane (DFE), a common aerosol propellant. We report a 33-year-old male who developed acute myocardial injury and global hypokinesis along with rhabdomyolysis, acute kidney injury, and fulminant hepatitis after 2 days' nearly continuous huffing. Workup for other causes, including underlying coronary artery disease, was negative. His cardiac function improved over time. The exact mechanism of DFE's effects is uncertain but may include catecholamine-induced cardiomyopathy, coronary vasospasm, or direct cellular toxicity.

    Open treatment of femoroacetabular impingement (FAI) through a surgical hip dislocation (SHD) approach has been reported to allow for improvement in pain and function. However, the approach require a trochanteric osteotomy and may be associated with high level of pain after surgery. Currently, there is no systematic approach for pain management after SHD for treatment of FAI. A retrospective chart review was used to collect data from 121 subjects (12 to 21 y and below) who received periarticular local infiltration analgesia (LIA, n=20), epidural analgesia (n=72), or intravenous patient-controlled analgesia (PCA, n=29) after SHD from January 2003 to June 2014. Verbal pain scores, opioid consumption, incidence of side effects/complications, and length of hospital stay (LOS) were recorded. All nonopioid medications with analgesic potential were included in the statistical models as potential confounding variables RESULTS:: Twelve hours after surgery, the odds of moderate/severe pain were higher in the PCA group (odds ratio, 20.5; 95% confidence interval (CI), 1.7-243.8; P=0.0166] and epidural group (odds ratio, 5.2; 95% CI, 0.7-92.0; P=0.3218) compared with the LIA group. There was no difference in pain scores across all groups 1 hour (P=0.0675) or 24 hours (P=0.3473) postoperatively. Total opioid consumption in the LIA group was 59.8% (95% CI, 15.0%-81.0%; P=0.0175) lower than the total opioid consumption in the epidural group and 60.7% (95% CI, 17.3-81.3; P=0.0144) lower than the total opioid consumption in the PCA group. LOS was increased in the epidural (mean difference, 22.1; 95% CI, 6.8-37.4 h; P=0.0051) and PCA (mean difference, 16 h; 95% CI, 1-31.5 h; P=0.0367) groups relative to the LIA group. There was 0 (0%) complication in the LIA group compared with 11 (15.3%) in the epidural group. LIA was more effective at controlling pain 12 hours after surgery in comparison with PCA with similar pain control to epidural. LIA was associated with significantly lower

We examined the pharmacokinetics, safety and efficacy of XaraColl following implantation in women undergoing total abdominal hysterectomy.Methods: Three XaraColl implants, each containing 50 mg bupivacaine hydrochloride, were implanted in 12 women undergoing total abdominal hysterectomy for a benign condition. Serum samples were obtained through 96 hours for pharmacokinetic analysis. Patients received acetaminophen 1000 mg every 6 hours, diclofenac 50 mg every 8 hours, and were given access to intravenous morphine for breakthrough pain via patient-controlled analgesia during the first 24 hours. Pain intensity was assessed at regular intervals using a 100 mm visual analog scale. Safety was assessed through 30 days.Results: The pharmacokinetic profile displayed a double peak in bupivacaine concentration with the second peak occurring up to 24 hours after the first and at a generally higher concentration. The time to maximum concentration (tmax varied from 0.5 to 24 hours (median 12 hours according to which peak predominated. The mean maximum concentration (Cmax was 0.22 µg/mL and the maximum individual Cmax was 0.44 µg/mL, which are well below the established systemic toxicity threshold. Morphine use was generally low (mean 16.8 mg; median 6.5 mg and compared favorably with institutional experience. At 6 hours post-surgery, 11 patients recorded pain scores ≤ 20 mm, 6 recorded ≤ 10 mm, and 2 reported no pain. Scores continued to decline throughout the study. The product was considered safe and well tolerated.Conclusion: Xara

    This study compared the efficacy of buprenorphine, carprofen, and a combination of the 2 analgesics in female baboons. Physiologic and behavioral parameters were assessed at baseline and postoperatively for 6 d by use of continuous noninvasive physiologic monitoring and twice-daily videotaping. Prior to surgery, all animals received a pre-emptive dose of either 0.01 mg/kg buprenorphine intramuscularly, 2.2 mg/kg carprofen intramuscularly, or a combination of 0.01 mg/kg buprenorphine and 2.2 mg/kg carprofen intramuscularly. All animals in the carprofen (n = 4) and buprenorphine+carprofen (n = 4) treatment groups appeared to have sufficient analgesia. Three of 4 animals in the buprenorphine group had adequate analgesia. The fourth animal had an elevated heart rate and spent less time standing during the postoperative period. In this study, the use of carprofen or a combination of carprofen plus buprenorphine provided more reliable postoperative analgesia than buprenorphine alone.

    Full Text Available Postoperative paraplegia is a rare complication after epidural analgesia and often occurs with spinal hematoma or cord injury. We present the case of a 16-year-old girl who suffered from a tumor mass in the neck and abdomen who underwent gynecologic operation. Preoperatively, liver metastasis was found by computed tomography. Pathologic findings revealed that the abdominal mass was an ovarian dermoid cyst. After the operation, the patient complained of paraplegia while receiving epidural analgesia for postoperative pain control. A peripheral primitive neuroectodermal tumor in the thoracic and lumbar spines with spinal cord compression was later detected using magnetic resonance imaging. Learning from this case, we suggest that when a patient is preoperatively diagnosed with tumor metastasis, back pain and soreness, spinal cord compression from tumor metastasis should be excluded before epidural analgesia is implemented.

  2. Molecular and cellular mechanisms of the age-dependency of opioid analgesia and tolerance

    Full Text Available Abstract The age-dependency of opioid analgesia and tolerance has been noticed in both clinical observation and laboratory studies. Evidence shows that many molecular and cellular events that play essential roles in opioid analgesia and tolerance are actually age-dependent. For example, the expression and functions of endogenous opioid peptides, multiple types of opioid receptors, G protein subunits that couple to opioid receptors, and regulators of G protein signaling (RGS proteins change with development and age. Other signaling systems that are critical to opioid tolerance development, such as N-methyl-D-aspartic acid (NMDA receptors, also undergo age-related changes. It is plausible that the age-dependent expression and functions of molecules within and related to the opioid signaling pathways, as well as age-dependent cellular activity such as agonist-induced opioid receptor internalization and desensitization, eventually lead to significant age-dependent changes in opioid analgesia and tolerance development.

    Epidural analgesia confers significant perioperative advantages to neonates undergoing surgical procedures but may be very technically challenging to place using a standard interlaminar loss-of-resistance to saline technique given the shallow depth of the epidural space. Thoracic epidural catheters placed via the caudal route may reduce the risk of direct neural injury from needle placement, but often pose higher risks of infection and/or improper positioning if placed without radiographic guidance. We present a detailed method of placing a fluoroscopically guided, tunneled transcaudal epidural catheter, which may reduce both of these risks. The accuracy and precision of this technique often provides adequate analgesia to allow for opioid-free epidural infusions as well as significant reductions in systemic opioids through the perioperative period. Opioid-free analgesia using a regional anesthetic technique allows for earlier extubation and reduced perioperative sedation, which may have a less deleterious neurocognitive effect on the developing brain of the neonate.

  4. Understanding Central Mechanisms of Acupuncture Analgesia Using Dynamic Quantitative Sensory Testing: A Review

    Full Text Available We discuss the emerging translational tools for the study of acupuncture analgesia with a focus on psychophysical methods. The gap between animal mechanistic studies and human clinical trials of acupuncture analgesia calls for effective translational tools that bridge neurophysiological data with meaningful clinical outcomes. Temporal summation (TS and conditioned pain modulation (CPM are two promising tools yet to be widely utilized. These psychophysical measures capture the state of the ascending facilitation and the descending inhibition of nociceptive transmission, respectively. We review the basic concepts and current methodologies underlying these measures in clinical pain research, and illustrate their application to research on acupuncture analgesia. Finally, we highlight the strengths and limitations of these research methods and make recommendations on future directions. The appropriate addition of TS and CPM to our current research armamentarium will facilitate our efforts to elucidate the central analgesic mechanisms of acupuncture in clinical populations.

    Full Text Available Background: The aim of this retrospective analysis of the obstetric regional analgesia (ORA in Jesenice General Hospital in year 2006 was to evaluate our work and present results. We analysed workload, quality of the analgesia and patients’ satisfaction. We also estimated the OR for vacuum extraction (VE in nulliparous labouring women having ORA. We compared quality of analgesia and total local analgesic consumption in nulliparous women having VE or spontaneous delivery.Methods: We performed retrospective analysis of labours with ORA in year 2006. All women received epiduraly mixture of 0.1 % bupivacaine with 2 µg of fentanyl per ml in intermittent boluses.The labour pain was assessed using visual analogue scale (VAS. We used median and interquartile range to describe distribution of these values and mean with standard deviation to describe distribution of other data (local anaesthetic consumption. We considered patient with pain VAS 3 or less adequately treated, VAS 4 and 5 sufficiently and VAS 6 and more insufficiently treated. We used odds ratio as measurement of risk for VE, t-test for differences in local anaesthetic consumption and Mann-Whitney test to evaluate differences in pain between tested groups.Results: 225 labouring women opted for ORA or 38 % of all labouring women in year 2006. We performed 224 ORA, 59 % during regular work, 41 % during turn of duty. 18 % of ORA were performed between 10 p.m. and 7.00 a.m. In 98 % of cases epidural analgesia was used. Anaesthesiologic work took 16 minutes in average (SD 6.06. Analgesia was started at VAS median 5 (IQR 4–6.5 and at average cervical dilatation 4.1 cm (SD 1.4. Average consumption of bupivacaine was 55 mg (SD 23.7 and fentanyl 91.7 µg (SD 46.5. Most common complications were inadequate analgesia, and misplacement of epidural catheter (10/222, dural tap (6/222, and unilateral analgesia (2/222. 70 labours were ended with VE (13 %; n = 532.

    Full Text Available Caudal epidural analgesia with bupivacaine is very popular in paediatric anaesthesia for providing intra- and postoperative analgesia. Several adjuvants have been used to prolong the action of bupivacaine. We evaluated the efficacy of clonidine added to bupivacaine in prolonging the analgesia produced by caudal bupivacaine in children undergoing sub-umbilical surgery. One hundred children, age one to three years, undergoing sub-umbilical surgery, were prospectively randomized to one of two groups: caudal analgesia with 1 ml/kg of 0.25% bupivacaine in normal saline (Group A or caudal analgesia with 1 ml/kg of 0.25% bupivacaine with 1 μg/kg of clonidine in normal saline (Group B. Post-operative pain was assessed for 24 hours using the FLACC scale. The mean duration of analgesia was significantly longer in Group B (593.4 ± 423.3 min than in Group A (288.7 ± 259.1 min; P < 0.05. The pain score assessed using FLACC scale was compared between the two groups, and children in Group B had lower pain scores, which was statistically significant. The requirement of rescue medicine was lesser in Group B. Clonidine in a dose of 1 μg/kg added to 0.25% bupivacaine for caudal analgesia, during sub-umbilical surgeries, prolongs the duration of analgesia of bupivacaine, without any side effects.

    We developed a new inhalation exposure method to evaluate effects of synthetic cannabimimetics that are being distributed as new, unregulated drugs in the Tokyo area. We selected the commercial product "SOUTOU" containing AB-CHMINACA and 5F-AMB as the test drug and dried marshmallow (Althaea officinalis) leaves as the negative control. A half cigarette packed with dried marshmallow leaves or SOUTOU was ignited, then mainstream smoke from each was delivered to five mice in an exposure box. After the cigarettes were fully consumed, neurobehavioral observations and a catalepsy test were performed at 15, 30 and 60 min after exposure. The effluent air from the exposure box was poured into impingers containing acetonitrile (first impinger) and dimethyl sulfoxide (second impinger). The resulting solutions were analyzed to assess decomposition of the synthetic cannabimimetics. Mice exposed to SOUTOU smoke showed many excitement behaviors and some suppressive behaviors at 15, 30 and 60 min. These clearly included cannabimimetic specific pharmacological actions. Negative control mice also showed some suppressive behaviors at 15 min but these were attenuated at later times, nearly disappearing at 60 min. In addition, the behavioral effects observed in controls were less pronounced than those in SOUTOU exposed mice. The inhalation exposure method developed in our study would be effective for determining cannabinoid specific pharmacological effects of illegal drugs, as well as for assessing the presence of active compound(s) by comparing the test substance with a negative control.

    Full Text Available During the inhalation of anaesthesia use of low fresh gas flow (0.35-1 L/min has some important advantages. There are three areas of benefit: pulmonary - anaesthesia with low fresh gas flow improves the dynamics of inhaled anaesthesia gas, increases mucociliary clearance, maintains body temperature and reduces water loss. Economic - reduction of anaesthesia gas consumption resulting in significant savings of > 75% and Ecological - reduction in nitrous oxide consumption, which is an important ozone-depleting and heat-trapping greenhouse gas that is emitted. Nevertheless, anaesthesia with high fresh gas flows of 2-6 L/min is still performed, a technique in which rebreathing is practically negligible. This special article describes the clinical use of conventional plenum vaporizers, connected to the fresh gas supply to easily perform low (1 L/min, minimal (0.5 L/min or metabolic flow anaesthesia (0.35 L/min with conventional Primus Draeger® anaesthesia machines in routine clinical practice.

  11. Alveolar proteinosis associated with aluminium dust inhalation.

    Chew, R; Nigam, S; Sivakumaran, P

    Secondary alveolar proteinosis is a rare lung disease which may be triggered by a variety of inhaled particles. The diagnosis is made by detection of anti-granulocyte-macrophage colony-stimulating factor antibodies in bronchoalveolar lavage fluid, which appears milky white and contains lamellar bodies. Aluminium has been suggested as a possible cause, but there is little evidence in the literature to support this assertion. We report the case of a 46-year-old former boilermaker and boat builder who developed secondary alveolar proteinosis following sustained heavy aluminium exposure. The presence of aluminium was confirmed both by histological examination and metallurgical analysis of a mediastinal lymph node. Despite cessation of exposure to aluminium and treatment with whole-lung lavage which normally results in improvements in both symptoms and lung function, the outcome was poor and novel therapies are now being used for this patient. It may be that the natural history in aluminium-related alveolar proteinosis is different, with the metal playing a mediating role in the disease process. Our case further supports the link between aluminium and secondary alveolar proteinosis and highlights the need for measures to prevent excessive aluminium inhalation in relevant industries. © The Author 2016.

    Beagle dogs were exposed, by inhalation, 5 to 11 years ago, to aerosols of 239 PuO 2 , 238 PuO 2 , or 239 Pu(NO 3 ) 4 , at six dose levels resulting in initial lung burdens ranging from ∼2 to ∼5500 nCi. Translocation of the plutonium to extrapulmonary sites was related to the physical-chemical characteristics of the plutonium compound. The highly insoluble 239 PuO 2 was retained primarily in the lung and associated lymph nodes, whereas 239 Pu(NO 3 ) 4 was much more soluble and translocated relatively rapidly to the skeleton and other extrapulmonary tissues. The 238 PuO 2 was intermediate in solubility and translocation characteristics. The hematologic effects of plutonium inhalation were most pronounced on lymphocyte populations. Evidence suggests that these effects result from irradiation of lymphocytes via the pulmonary lymph nodes with insoluble 239 PuO 2 , and via these same lymph nodes, extrapulmonary lymph nodes, and bone marrow lymphocytes with the more soluble forms, i.e., 238 PuO 2 and 239 Pu(NO 3 ) 4 . There is no evidence suggesting that these exposures increase the risk of developing myeloid or lymphoid neoplasia. 8 refs., 4 figs., 3 tabs

    Medical literature provides only scarce data about the degree of pain experienced by patients undergoing a bone marrow aspiration and biopsy (BMAB), and little is known about the factors that can modify the perception of pain. In this study, we evaluated the effectiveness of a combination of analgesia and anxiolysis in reducing the pain score of patients undergoing BMAB. Eighty-four consecutive adult patients underwent BMAB after local anesthesia with 5 mL of lidocaine hydrochloride 1% aqueous solution in the left posterior superior iliac crest. Analgesia was obtained with acetaminophen 650 mg and oxycodone 10 mg, and anxiolysis was obtained with lorazepam 2 mg, all drugs given once orally 30 min before the procedure. We assessed the pain level with the Wong-Baker Faces Pain Rating Scale, which distinguishes six levels of pain, from 0 to 5. The 34 patients who received an oral administration of analgesia and anxiolysis reported pain at lower levels, i.e., in the range of 0-2, more frequently than the 50 patients who underwent BMAB without analgesia/anxiolysis (78% vs 64%, respectively). Among several predictors analyzed using a multivariate regression model, three were found to be associated with decreased pain level: the use of analgesia/anxiolysis, male sex, and increase in age (all with p values <0.05). Length of the extracted bone specimen, body mass index, and need of a spinal needle for anesthesia in obese patients did not predict for pain level. An oral administration of prophylactic regimen of analgesia and anxiolysis, at the above-mentioned doses, produced a statistically significant reduction of the perception of pain in patients undergoing BMAB, but its effect did not seem to provide a major and clinically significant reduction of pain level.

    Epidural analgesia is the commonest mode for providing pain relief in labour, with a combination of bupivacaine and fentanyl most often used in practice. To test whether late-preterm and term neonates exposed to opioids in epidural analgesia in labour are more likely to develop respiratory distress in the immediate neonatal period. A case-control study was conducted of singleton infants born during January 2006 to December 2010. Cases were neonates ≥34 weeks gestation, who developed respiratory distress within 24 h of life requiring supplemental oxygen ≥2 h and/or positive pressure ventilation in the neonatal intensive care unit. Controls were gestation and site-matched neonates who did not develop any respiratory distress within the same period. The information on exposure to epidural analgesia and on potential confounding variables was obtained from the standardised delivery record, routinely filled out on all women admitted to the labour wards. In our study, 206 cases and 206 matched controls were enrolled. Exposure to epidural analgesia was present in 146 (70.9%) cases as compared with 131 (63.6%) of the controls. The association between exposure to epidural analgesia and respiratory distress in neonates was statistically significant upon adjustment for all potential confounders (adjusted OR: 1.75, 95% CI 1.03 to 2.99; p = 0.04). When data was separately analysed for term and late-preterm infants, the results were consistent across these subpopulations, showing no interaction effect. Late-preterm and term infants exposed to maternal epidural analgesia in labour are more likely to develop respiratory distress in the immediate neonatal period.

  15. The effect of smoking status on burn inhalation injury mortality.

    Three factors that effect burn mortality are age, total body surface of burn (TBSA), and inhalation injury. Of the three, inhalation injury is the strongest predictor of mortality thus its inclusion in the revised Baux score (age+TBSA+17* (inhalation injury, 1=yes, 0=no)). However, the weighted contribution of specific comorbidities such as smoker status on mortality has traditionally not been accounted for nor studied in this subset of burn patients. We therefore sought to examine the impact of current tobacco and/or marijuana smoking in patients with inhalation injury. A retrospective analysis of patients admitted to a regional burn center from 2002 to 2012. Independent variables analyzed included basic demographics, burn mechanism, presence of inhalation injury, TBSA, pre-existing comorbidities, and smoker status. Bivariate analysis was performed and logistic regression modeling using significant variables was utilized to estimate odds of mortality. There were a total of 7640 patients over the study period. 7% (n=580) of the burn cohort with inhalation injury were included in this study. In-hospital burn mortality for inhalation injury patients was 23%. Current smokers (20%) included cigarette smokers and marijuana users, 19% and 3%, respectively. Preexisting respiratory disease (17%) was present in 36% of smokers compared to 13% of non-smokers (psmoke inhalation injury. Future prospective studies in human and/or animal models are needed to confirm these findings. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

    Conclusions: BUD/FORM inhalation has an inotropic effect on diaphragm muscle, protects diaphragm muscle deterioration after endotoxin injection, and inhibits NO production. Increments in muscle contractility with BUD/FORM inhalation are induced through a synergistic effect of an anti-inflammatory agent and 02-agonist.

    A case study was carried out in 2006-2007 to assess the actual cement dust exposure among construction workers involved in a full-scale construction project and as a comparison among workers involved in various stages of cement and concrete production. Full-shift personal exposure measurements were performed for several job types. Inhalable dust and cement dust (based on analysis of elemental calcium) concentrations were determined. Inhalable dust exposures at the construction site ranged from 0.05 to 34 mg/m3, with a mean concentration of 1.0 mg/m3. For inhalable cement dust mean exposure was 0.3 mg/m3 (range 0.02-17 mg/m3). Reinforcement and pouring workers had the lowest average concentrations. Inhalable dust levels in the ready-mix and pre-cast concrete plants were, on average, below 0.5 mg/m3 for inhalable dust and below 0.2 mg/m3 for inhalable cement dust. Highest dust concentrations were measured in cement production, particularly during cleaning tasks (inhalable dust GM=55 mg/m3; inhalable cement dust GM=33 mg/m3) at which point the workers wore personal protective equipment. Elemental measurements showed highest but very variable cement percentages in the cement plant and very low percentages of cement during reinforcement work and pouring.
