Post-operative nausea and vomiting (PONV) is the distressing situation for patients &amp; caregivers. Various groups of pharmalogical agents are used for prophylaxis in high risk patients for PONV but they have their own advantage and disadvantages. Recent metaanalysis on intravenous use of 5% dextrose showed conflicting results with risk of hyperglycemis. So in this study we plan to use intravenous 2% dextrose in ringer lactate for prevention of PONV in laparoscopic cholecystectomy patients.  This prospective randomized double-blind controlled study was conducted in 60 American Society of Anaesthesiologist 1 &amp; 11 patients, age 20-55 years undergoing elective laparoscopic cholecystectomy under general anaesthesia. Patients were randomly divided into two groups: group DRL received 2% dextrose in ringer lactate and group RL received ringer lactate. Allocate fluid was started at induction of anaesthesia and continued post-operatively up to 6hr. Incidence and severity of PONV was measured as a primary outcome. Secondary outcome includes comparison of blood sugar level, requirement of rescue antiemetic, time of oral acceptance of food &amp; time of discharge between two groups. Mean between two groups were compared with student t test. The critical value of ‘p’ indicating the probability of significant difference was taken as&amp;#60;0.05 for comparison.  Incidence and severity of PONV was less in group DRL than group RL. Blood sugar level was higher in group DRL but within the normal range. Time of oral feed and time to discharge was early in group DRL.  Intravenous 2% dextrose in ringer lactate reduces the incidence and severity of PONV in laparoscopic cholecystectomy patients.
