AIMS:To evaluate the antiemetic efficacy of ondansetron, metoclopramide or small dose of propofol following ear, nose and throat (ENT) surgery.MATERIALS AND METHODS:A prospective randomized study involving 60 patients, both children and adults undergoing elective ENT surgery under standard general anesthesia. At the completion of surgery the patients received either 0.1 mg/kg of ondansetron or 0.2 mg/kg of metoclopramide or 0.5 mg/kg of propofol intravenously. The patients were observed for 24 hrs after operation for any occurrence of nausea and vomiting.RESULTS:The incidence of postoperative nausea and vomiting (PONV) during first 24 hrs was recorded in 20%, 70%, 50% of patients who had received ondansetron, metoclopr-amide or propofol respectively (p < 0.05). Fewer patients given ondansetron needed rescue antiemetic. The incidence of PONV was higher following middle year surgery.CONCLUSION:It was concluded that ondansetron was most effective in preventing occurrence of PONV while metoclopramide was least effective. Propofol was effective only in 50% of patients, thus not recommended for routine use.
The brachial plexus in infraclavicular region can be blocked by various approaches. Aim of this study was to compare two approaches (coracoid and clavicular) regarding success rate, discomfort during performance of block, tourniquet tolerance and complications. The study was randomised, prospective and observer blinded. Sixty adult patients of both sexes of ASA status 1 and 2 requiring orthopaedic surgery below mid-humerus were randomly assigned to receive nerve stimulator guided infraclavicular brachial plexus block either by lateral coracoid approach (group L, n = 30) or medial clavicular approach (group M, n = 30) with 25-30 ml of 0.5% bupivacaine. Sensory block in the distribution of five main nerves distal to elbow, motor block (Grade 1-4), discomfort during performance of block and tourniquet pain were recorded by a blinded observer. Clinical success of block was defined as the block sufficient to perform the surgery without any supplementation. All the five nerves distal to elbow were blocked in 77 and 67% patients in groups L and M respectively. Successful block was observed in 87 and 73% patients in groups L and M, respectively (P > 0.05). More patients had moderate to severe discomfort during performance of block due to positioning of limb in group M (14 vs. 8 in groups M and L). Tourniquet was well tolerated in most patients with successful block in both groups. No serious complication was observed. Both the approaches were equivalent regarding success rate, tourniquet tolerance and safety. Coracoid approach seemed better as positioning of operative limb was less painful, coracoids process was easy to locate and the technique was easy to learn and master.
