Review Meta AnalysisLocal anaesthesia for pain relief after laparoscopic cholecystectomy--a systematic review.
Local anaesthetics (LA) are increasingly being used intraoperatively for the prevention of postoperative pain. The efficacy of local anaesthetic infiltration into incision sites has only been shown in patients undergoing inguinal herniorrhaphy. However, in one meta-analysis of the literature, intraperitoneal LA have been shown to be effective for pain relief following laparoscopic cholecystectomy (LC). ⋯ Although side effects are rare, the dose of LA should be monitored closely to avoid toxicity. Future studies should be directed towards determining whether the analgesic effects of LA are via peripheral mechanisms or systemic absorption. The explanation for the wide interindividual variation in pain following LC should also be better investigated.
