To evaluate and compare the effects of pre-operative single oral dose of tramadol and famotidine on gastric secretions pH and volume in patients electively scheduled for laparoscopic cholecystectomy.
Randomized control trial. Department of Anaesthesia, King Saud University Riyadh, Saudi Arabia, from August 2011 to June 2013. Ninety adult, ASA-I and II patients scheduled for laparoscopic cholecystectomy were included in the study. Patients were randomly assigned to receive pre-operatively either placebo [Group-C, n=30] , oral tramadol 100 mg [Group-T, n=30] or famotidine 40 mg [Group-F, n=30] . After induction of general anaesthesia, gastric fluid was aspirated through orogastric tube. The gastric secretions volume and pH was measured using pH meter. There was no statistically difference between groups in age, weight and gender. The gastric secretions mean pH was 2.06 +/- 0.22, 2.04 +/- 0.20, 5.79 +/- 0.77 and volume was 0.59 +/- 0.17, 0.59 +/- 0.14 and 0.28 +/- 0.16 ml/kg in Group-C, Group-T and Group-F respectively. There was a significant statistical difference in the mean pH values between Group-C vs. Group-F [p < 0.001] and Group-Tvs. Group-F [p < 0.001] . Statistically significant difference was also found in the mean gastric secretions volume between Group - C vs. Group-F [p < 0.001] and Group-Tvs. Group-F [p < 0.001] . There was no significant difference in the mean gastric fluid pH values [p=0.99] and mean gastric secretions volume [p=0.99] between Group-Tand Group-C. As compared to famotidine, pre-operative single oral dose of tramadol was unable to elevate the desired level of gastric fluid pH [>2.5] and decrease in gastric secretions volume [< 0.4ml/kg]
