Background: Epidural anaesthesia and analgesia in orthopaedic surgeries helps to prevent thromboembolic phenomenon by increasing venodynamics. Adequate post-operative analgesia with good patient satisfaction has been observed with this technique. Objective:To assess the duration of postoperative analgesia and complications in patients receiving epidural anaesthesia with Morphine, Midazolam and Pethidine in combination with Bupivacaine. Methods:We prospectively studied 75 patients who were scheduled for elective lower limb orthopaedic surgery with epidural anaesthesia at Lumbini Medical College, Palpa from 2010 March to 2012 March. They were randomly divided by lottery method into three equal groups. Group 'A' (BP) received 50 mg epidural Pethidine (3 ml) with 13 ml of 0.5% Bupivacaine. Group 'B' (BM) received 5 mg (3 ml) epidural Morphine with 13 ml of 0.5% Bupivacaine and Group 'C' (BMM) received 5 mg (1 ml) epidural Morphine with 13 ml 0.5% Bupivacaine and 2 mg (2 ml) epidural Midazolam.All the patients were observed for 24 hours for quality of analgesia and other side effects like nausea, vomiting and pruritus. Data were analysed by Statistical Package for Social Sciences (SPSS-16) software. Results:The result of the study shows the duration of analgesia was prolonged in BM group than BP group and even more so in BMM group (p value <0.001). Incidence of nausea and vomiting in BMM group was lower than in BP and BM group but statistically the difference was not significant (p value: 0.489). Pruritus was absent in BP group, less in BMM group while significantly higher in BM group. Conclusion:The use of epidural Morphine and Midazolam in combination with Bupivacaine is the satisfactory method of post operative analgesia. When Midazolam is added, duration of analgesia can be increased with decrease in incidence of nausea, vomiting and pruritus. METHODSWe prospectively studied 75 8. Weissman C.

Adequate post operative analgesia in children provides satisfactory psychological objective of this study was to compare the post operative analgesia requirement and child satisfaction between two groups, general anaesthesia(GA) alone and GA in combination with penile nerve block. This prospective randomized study was conducted in 50 children aged 6 to 14 years, who underwent circumcision. The boys were randomly allocated into two groups. Group A (n = 25) received GA with Single shot ketamin 2mg/kg IV plus midazolam 0.1 mg/kg and dorsal penile nerve block at the base of penis prior to circumcision with and Group B (n = 25) received GA with ketamine 2mg/kg IV plus midazolam 0.1 mg/kg plus halothane by laryngeal mask. Severity of pain was assessed quantitatively by children's hospital eastern Ontario pain scale (CHEOPS). The pain intensity was assessed at one hour A1 in group A and B1 for group B and at two hourA2 for group A and B2 for group B during postoperatively period for two hours. Statistical analysis was done by SPSS method. The post operative analgesia was satisfactory with CHEOPS score 6 or <6 in group A 1. In group A 2 twenty two out of twenty five cases had CHEOPS score <6.Where as in group B1 and B2 it was > 6 .Which was statistically 100% significant. In conclusion, combined penile nerve block in combination with intravenous ketamine plus midazolam is the satisfactory method of Post operative pain management in children undergoing circumcision.
