AIM:To investigate the effect of intercostals neural blockade(INB)combining with intravenous dexamethasone on postoperative pain,nausea and vomiting and rehabilitation after laparoscopic cholecystectomy(LC).METHODS:Seventy-two patients with ASA I-Ⅱ undergoing LC were randomly divided into three groups with twenty-four patients in each group.Group DI received intravenous dexamethasone infusion before induction combining with INB.Group I only received INB.Group C was control group.Propofol and remifentanil consumption were recorded,postoperative pain and fatigue were assessed according to a pain and fatigue severity score using a subjective analog visual scale(VAS)1,4,12,and 24 h after the surgery.The incidence of postoperative nausea and vomiting,times to first enterocinesia,flatus and hospital discharge were recorded.RESULTS:Propofol and remifentanil consumption,postoperative pain and fatigue scores 4,12,24 h after surgery,the postoperative nausea and vomiting incidences,times to first enterocinesia and flatus,times to hospital discharge were significantly lower in Group DI and I than those in Group C(P
