Background Intraperitoneal local anaesthetic nebulization is a relatively novel approach to
pain management after laparoscopic surgery. This randomized, double-blind, placebo-
controlled trial evaluated the effects of intraperitoneal ropivacaine nebulization on pain
control after laparoscopic cholecystectomy. Methods Patients undergoing laparoscopic
cholecystectomy were randomized to receive intraperitoneal nebulization of ropivacaine
1%(3 ml) before surgical dissection and normal saline 3 ml at the end of surgery …
