Effect of Intraperitoneal Local Anesthetic on Patients Underwent Laparoscopic Cholecystectomy / 中国微创外科杂志

ABSTRACT

Objective To investigate the effect of intraperitoneal local anesthetic on patients undergone laparoscopic cholecysteetomy (LC).Methods Thirty-six patients (ASAⅠ-Ⅱ),who were undergoing selective LC were randomly divided into there groups.GroupⅠreceived preoperational anesthetic spary with 30 ml of 0.5% ropivacaine.GroupⅡwas given the anesthetic at a same dosage after the operation.While groupⅢwas set as a control by using 0.9% NaCl instead of ropivacaine.The LC was completed under general anesthesia.After the operation,visual analog scale (VAS) was recorded at 6,24,and 48 hours to evaluate the degree of postoperative pain.Meanwhile,the number of the patients who received anesthetics after the surgery,as well as the incidence rates shoulder or back pain and nausea or vomiting were recorded.Results Postoperative VAS of the groupⅠwas significantly lower than that of the other two groups,while the VAS of groupⅡwas significantly lower than that in groupⅢ(both P0.05). Conclusions Intraperitoneal local anesthetic can significantly reduce postoperative pain after LC.It is more effective to give local anesthetic at the end of the procedure than using it before operation.
