Randomized Controlled Trial
The effect of intraperitoneal ropivacaine on pain after laparoscopic colectomy: a prospective randomized controlled trial.
Although laparoscopic procedures are becoming more common, postoperative pain remains a major factor causing delayed patient recovery. There have been several trials to reduce pain by instilling local anesthetics into the peritoneal cavity, but there has been no study on prolonged (∼300 min) or intensive surgery. We investigated the analgesic effect of intraperitoneal ropivacaine instillation after laparoscopic colectomy. ⋯ The intraperitoneal instillation of ropivacaine was effective in reducing postoperative pain and in shortening the recovery course after laparoscopic colectomy. The additional instillation of ropivacaine at the end of the surgery proved even more effective.
