RESUMEN
This systematic review and meta-analysis aimed to assess the effects of pre and intraoperative lidocaine infusion on short-term recovery quality after laparoscopic bariatric surgeries. In the search across MEDLINE, Embase, and Cochrane databases, we considered randomized controlled trials comparing intravenous lidocaine vs placebo (saline) for patients with obesity undergoing laparoscopic bariatric surgery. Seven studies (640 patients) were included. The lidocaine group had a significantly higher recovery quality score, a lower morphine consumption, and a notably reduced rate of nausea and vomiting compared with the placebo group. Additionally, Lidocaine infusion was associated with a shorter hospital stay, while no significant difference was observed in the time to bowel function recovery between both groups. In conclusion, lidocaine infusion before and during laparoscopic bariatric surgery contributes to an enhanced quality of recovery.
