Introduction: Regional analgesic techniques with infiltration of local anesthetic represent a cornerstone in modern postoperative pain management strategies after laparoscopic surgery. If used in a right concentration, it could help in attenuation of postoperative pain with better pulmonary performance and less morbidity. Aim: to compare the effect of different concentrations of intraperitoneal bupivacaine to obtain proper pain relief after laparoscopic bariatric surgery and evaluating its effect on pulmonary functions. Patients and methods: One hundred and twenty morbidly obese patients were included in this study. Patients were divided into three group. Group (A) patients received 50 ml bupivacaine 0.25% into the coelomic cavity. Group (B) patients receive 50 ml bupivacaine 0.125% into the coelomic cavity. Group (C) control group (n=36): patients receive 50 ml of normal saline into the coelomic cavity. VAS score and pulmonary function study were examined before and at regular intervals after surgery. Total analgesic requirements and time to first analgesic rescue was recorded. Results: VAS in group (A) was significantly lower than group (C) 2 hours after surgery and lower in group (A) compared with group (B&C) at 4 and 6 hours postoperative. Postoperative morphine consumption was lower in group (A) during the first 24 hours when compared to group (B & C) respectively. Both FVC and FEV1 were higher in group (A) compared to group (B&C) at 6hours postoperative. Conclusion: intraperitoneal injection of bupivacaine 0.25% is an efficient method of decreasing the postoperative pain with better preservation of pulmonary functions in morbidly obese patients undergoing laparoscopic bariatric surgery.
