Background: The present study aims to standardize the timing of intraperitoneal instillation of ropivacaine in laparoscopic cholecystectomy. Materials & Methods: The present study was conducted on 90 patients who were to undergo elective laparoscopic cholecystectomy. Patients were divided into 3 groups of 30 each. Group A: patients received 20 ml of 0.5% ropivacaine instillation intraperitoneally just after the insertion of laparoscopic ports at the beginning of surgery. Group B: patients received 20 ml of 0.5% ropivacaine instillation intraperitoneally just before the removal of laparoscopic ports at the end of the surgery. Group C: patients received 10ml of 0.5% ropivacaine instillation intraperitoneally just after the insertion of laparoscopic ports at the beginning of surgery and 10ml of 0.5% ropivacaine instillation intraperitoneally just before the removal of laparoscopes at the end of the surgery. Results: Maximum patients were seen in age group >60 years (9) in group A, 51-60 years (11) in group B and 41-50 years (10) in group C. Pruritis, respiratory depression and allergic reaction was not present in any group. Urinary retention was present in 1 patient in group A and B while 2 in group C. Fever was present 1 patient each in group A and C, morphine was given to 9 in group A, 15 in group B and 39 in group C. Inter- group comparison was non- significant (P> 0.05). A non- significant difference in mean pulse rate in all groups (P> 0.05). Conclusion: Authors found that ropivacaine instillation in all doses found to be equally effective in all groups.
