Background:Opioid-induced side effects such as nausea and vomiting and pruritus are common and may be more debilitating than pain itself. We performed a study to assess the efficacy of dexamethasone in reducing postoperative nausea, vomiting, and pruritus in patients receiving neuraxial anesthesia with meperidine.Methods:Fifty-two women undergoing cesarean section were enrolled in the study. The control group and dexamethasone group received intravenously normal saline and dexamethasone, respectively, before spinal anesthesia. The occurrence of postoperative nausea, vomiting, and pruritus was assessed for 24 h in both groups.Results:The overall incidence of nausea and vomiting during the 24 h follow-up period was 37% and 22.2% for group saline and 20% and 12% for group dexamethasone, respectively (P=0.175, 0.469). The incidence of pruritus was not significantly different between the two groups. Pruritus severity was significantly less in the dexamethasone group than in the saline group (P=0.019).Conclusion:Prophylactic dexamethasone does not reduce the incidence of subarachnoid meperidine-induced nausea, vomiting, and pruritus in women undergoing cesarean delivery.
BackgroundEndoscopic retrograde cholangiopancreatography (ERCP) is a painful procedure that requires analgesia and sedation.ObjectivesIn this study, we compared the analgesic and sedative effects of propofol-ketamine versus propofol-fentanyl in patients undergoing ERCP.MethodsIn this clinical trial, 72 patients, aged 30 - 70 years old, who were candidates for ERCP were randomly divided into two groups. Before the start of ERCP, both groups received midazolam 0.5 - 1 mg. The intervention group (PK) received ketamine 0.5 mg/kg, and the control group (PF) received fentanyl 50 - 100 micrograms. All patients received propofol 0.5 mg/kg in a loading dose followed by 75 mcg/kg/minute in an infusion. The patients, the anesthesiologist, and the endoscopist were unaware of the medication regimen. Sedation and analgesia quality (based on a VAS), blood pressure, respiratory rate, heart rate, arterial oxygen saturation, recovery time (based on Aldrete scores), and endoscopist and patient satisfation were recorded.ResultsThe sedative effects were equal in the two groups (P > 0.05), but the analgesic effects were higher in the PF group than in the PK group (P < 0.05). The PK group had higher blood pressure levels in the eighth minute. Respiratory rate, heart rate, and arterial oxygen saturation showed no significant differences between the groups (P > 0.05). Endoscopist satisfaction, patient satisfaction, and recovery time showed no significant differences between the two groups (P > 0.05).ConclusionsThe results showed that the sedative effect of propofol-ketamine was equal to the propofol-fentanyl combination during ERCP. To prevent respiratory and hemodynamic complications during ERCP, the propofol-ketamine combination should be used in patients with underlying disease.
Introduction:Endotracheal intubation is essential during general anesthesia and muscle relaxant drugs provide ideal conditions for this purpose. The objective of this study was to evaluate the intubating condition of remifentanil combined with propofol without muscle relaxant.Materials and Methods:In this prospective randomized study, 60 children aged 3-12 years, American Society of Anesthesiologists physical status I and II were included. All the children were premedicated with 0.05 mg/kg midazolam and 1.5 mg/kg lidocaine 5 min before the induction of anesthesia with 3 mg/kg propofol. Then, they were allocated randomly to receive either 2 μg/kg remifentanil (group R) or 1.5 mg/kg succinylcholine (group S). Tracheal intubation was attempted 90 s after the administration of propofol. The quality of intubation was assessed by using Copenhagen score based on jaw relaxation, ease of laryngoscopy, position of vocal cord, coughing and limb movement. Heart rate and blood pressure were recorded before and after induction, and 1, 3, 5 min after intubation.Results:There was no significant difference in intubating condition between the two groups (P = 0.11). Intubation condition was excellent in 26 of 30 (86.7%) patients in the group R compared with 30 (100%) patients in the group S. We observed significant difference in heart rate and systolic blood pressure over time between two groups (P = 0.02, P = 0.03 respectively). After intubation, we had higher heart rate and systolic blood pressure with a significant difference in group S compared with group R (P = 0.006, P = 0.018). None of the children had a chest rigidity, laryngospasm, and hypoxia.Conclusions:In premedicated children, propofol-remifentanil combination provides adequate conditions for tracheal intubation that is comparable with succinylcholine. Hemodynamic response to laryngoscopy and tracheal intubation was controlled better in group R.
Aim:Azoospermia is the most common form of male factor infertility, due to which sperms are retrieved for intra-cytoplasmic sperm injection (ICSI) under general or local anesthesia. The aim of the present study was to compare the efficacy of general and local anesthesia in an attempt to extract a sufficient quality of sperm for men with azoospermia, who intend to undergo ICSI.Materials and Methods:A total number of 50 patients with azoospermia, who were within the age range of 20-40, were randomly scheduled for testicular sperm extraction with either general or local anesthesia before ICSI. The hormonal abnormalities and severe varicocele were evaluated and treated before the testicular sperm extraction. The inclusion criteria obliged the researchers to focus on men with azoospermic, those who were diagnosed by two semen analyses after a 3-day abstinence from coitus according to the modified WHO criteria, and 19< body mass index ≤28. The concentration, motility, and morphology of the spermatozoa of the two groups were also compared.Results:A total number of 76 men, with a mean age of 35.1 ± 6.0, were selected, 26 were excluded from the study, and the remaining participants were randomly divided into two groups such as general anesthesia and lidocaine group. According to the results, the differences between the values of sperm parameters within various hours after the testicle biopsy were not statistically significant. Also, there was no significant difference between the two groups in terms of sperm motility and sperm morphology during various timing after the processing.Conclusion:The present study demonstrated that there was no evidence found for values of sperm parameters between the two groups, undergoing local and general anesthesia, within various hours after the testicular biopsy. Further investigations with more focus on concentration-dependent lidocaine on human sperm parameters need to be carried out.
