Abstract
We reviewed the effectiveness of intraperitoneal instillation of local anesthetic on pain after gynecologic laparoscopic surgery. Sources included the Cochrane Central Register of Controlled Trials, MEDLINE/PubMed, EMBASE, and Ovid MEDLINE In-Process & Other Non-Indexed Citations databases, and abstracts, reference lists, and randomized controlled trial (RCT) registries. The 7 included RCTs compared pain scores after administration of intraperitoneal analgesics or placebo/control during gynecologic laparoscopic surgery with benign indications. Outcome measures were pain scores (per visual analog scale) at 1 to 2, 4 to 6, and 24 hours postoperatively. Pain scores were significantly lower in the groups receiving local anesthesia at 1 to 2 hours (weighted mean difference [WMD], −1.82; 95% confidence interval [CI], −2.55 to −1.08]) and 4 to 6 hours postoperatively (WMD, −2.00; 95% CI, −3.64 to −0.35), but were similar at 24 hours (WMD, −1.43; 95% CI, −1.15 to 0.96). Local analgesia instilled intraperitoneally significantly decreased pain during a 6-hour interval after gynecologic laparoscopy.
