post laparoscopic pain control using local anesthesia through laparoscopic port sites

background: severe abdominal pain is not common after laparoscopic surgeries, but acute or chronic pain after operation is considerable in some patients. post-operative pain control after laparoscopic surgeries, is conventionally achieved using analgesics such as non-steroidal anti-inflammatory drugs (nsaids) and narcotics, but their administration has a lot of side effects. this study compares the efficacy and side effects of local anesthetic drugs versus conventional analgesics in post-operative pain control. materials and methods: this prospective investigation was conducted into two groups of patients (n=93). group 1, as control group, was given conventional analgesics such as narcotics and nsaids. in investigational group, at the end of laparoscopic surgery, prior to port withdrawal, a local anesthetic mixture, a short acting (lidocaine 2%) plus a long acting (bupivacaine 0.5%) is instilled through the port lumen between the abdominal wall layers. the efficacy of both types of medications was compared to their efficacy and side effects. results: 85% of the control group, received 5 to 20 ml morphine for pain control while the others were controlled with trans-rectal nsaids. in the treatment group, the pain of 65% of the patients was controlled only by local anesthetic drugs, 30% required nsaids and the other 5% required narcotics administration for pain control. conclusion: the administration of local anesthetic drugs after laparoscopic surgery is an effective method for pain control with a low complications rate and side effects of narcotics.
