Selected AbstractsUse of activated protein C has no avail in the early phase of acute pancreatitisHPB, Issue 6 2008Sinan Akay Abstract Objectives. Sepsis and acute pancreatitis have similar pathogenetic mechanisms that have been implicated in the progression of multiple organ failure. Drotrecogin alfa, an analogue of endogenous protein C, reduces mortality in clinical sepsis. Our objective was to evaluate the early therapeutic effects of activated protein C (APC) in a rat model of acute necrotizing pancreatitis. Subjects and method. Acute necrotizing pancreatitis was induced by intraductal injection of 5% Na taurocholate. Hourly bolus injections of saline or recombinant human APC (drotrecogin alfa) was commenced via femoral venous catheter four hours after the induction of acute pancreatitis. The experiment was terminated nine hours after pancratitis induction. Animals in group one (n=20) had a sham operation while animals in group two (n=20) received saline and animals in group three (n=20) received drotrecogin alfa boluses after acute pancreatitis induction. Pancreatic tissue for histopathologic scores and myeloperoxidase, glutathione reductase, glutathione peroxidase, and catalase activites were collected, and blood for serum amylase, urea, creatinine, and inleukin-6 measurements was withdrawn. Results. Serum amylase activity was significantly lower in the APC treated group than the untreated group (17,435±432 U/L vs. 27,426±118 U/L, respectively). While the serum interleukin-6 concentration in the APC untreated group was significantly lower than the treated group (970±323 pg/mL vs. 330±368 pg/mL, respectively). Conclusion. In the early phase of acute pancreatitis, drotrecogin alfa treatment did not result in a significant improvement in oxidative and inflammatory parameters or renal functions. [source] Fentanyl reduces desflurane-induced airway irritability following thiopental administration in childrenACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2006J. Lee Background:, Airway irritation is a major drawback of desflurane anesthesia. This study was designed to evaluate the effect of intravenous fentanyl given before thiopental induction on airway irritation caused by a stepwise increase in desflurane in children. Methods:, Eighty children (2,8 years) were enrolled in a randomized, double-blind study. Forty received saline and 40 received 2 ,g/kg of fentanyl intravenously; this was followed by thiopental sodium 5 mg/kg in both groups. Patients were assistant-ventilated with desflurane 1%, which was then increased by 1% every six breaths up to 10%. During this period, cough, secretion, excitation and apnea were graded and the desflurane concentration at which airway irritation symptoms first occurred was recorded. The results were analyzed using Pearson's chi-squared test. Results:, The incidence of typical airway irritation events was lower with fentanyl than with saline (cough, 2.5% vs. 42.5%; secretion, 27.5% vs. 82.5%; excitation, 10% vs. 82.5%; apnea, 20% vs. 65%; P < 0.05). The mean expired desflurane concentration at which the first airway irritation symptom occurred was greater with fentanyl than with saline (7.3% vs. 5.5%, P < 0.05). Conclusions:, Intravenous fentanyl in children reduces airway complications caused by desflurane. [source] The effect of injecting botulinum toxin type a into the calf muscles on freezing of gait in Parkinson's disease: A double blind placebo-controlled pilot studyMOVEMENT DISORDERS, Issue 6 2007Tanya Gurevich MD Abstract Objective To assess the effect on freezing of gait (FOG) of botulinum toxin type A (BTX-A) injections in advanced Parkinson's disease (PD) patients. Method BTX-A 150 IU or normal saline was injected into each leg's calf muscles by a blinded investigator. FOG severity was assessed at set intervals (6-month follow-up). Results Eleven age- and disease severity-matched PD patients with disabling FOG participated. Six patients received BTX-A and 5 received saline. No improvement was observed in either group over time. Leg weakness and falls lead to early termination. Conclusion BTX-A injections to the legs did not improve FOG and might increase fall risk. © 2007 Movement Disorder Society [source] Use of Dexamethasone on the Prophylaxis of Nausea and Vomiting After Tympanomastoid Surgery,THE LARYNGOSCOPE, Issue 7 2001Yun-Hou Liu MD Abstract Objective The aim of this study was to evaluate the prophylactic effect of dexamethasone on postoperative nausea and vomiting (PONV) in patients undergoing tympanomastoid surgery. Study Design Eighty patients (n = 40 in each of two groups) undergoing tympanomastoid surgery under general anesthesia were enrolled in this randomized, double-blind, placebo-controlled study. Methods After tracheal intubation, group 1 received 10 mg dexamethasone intravenously, whereas group 2 received saline intravenously. Several parameters concerning with the occurrence of PONV were evaluated. Results We found that dexamethasone reduced the total incidence of nausea and vomiting by 45%, with a 95% confidence interval of 26% to 64% (P <.001). Furthermore, dexamethasone reduced the incidence of vomiting episodes >4 times and the incidence of patients requiring rescue antiemetics (P <.05). Conclusion Dexamethasone at a dosage of 10 mg administered intravenously is effective in preventing PONV in patients undergoing tympanomastoid surgery. [source] | ||||||||||
