This approach has been design ed to provide adequate analgesia while minimizing exposure to adverse events
Background : Laparoscopic cholecystectomy has advantages over the open procedure for postoperative pain .
However , a systematic review of postoperative pain management in this procedure has not been conducted .
A new method of preemptive analgesia in laparoscopic cholecystectomy
Background Although laparoscopic cholecystectomy ( LC ) results in less pain then open cholecystectomy , it is not a pain-free procedure . The aim of this study was to test a new method of preemptive analgesia . Methods By simple r and omization 60 patients were assigned to two groups ( 30 in each group ) . Group A , the placebo group , received 200 ml of 0.9 % saline , and group B received 5 mg/kg of a local anesthetic solution ( ropivacaine ) in 200 ml of 0.9 % saline . Local anesthetic or place solution were administer before creation of the pneumoperitoneum . Results Pain intensity , as rated by visual analog and verbal rating scales , and stress response data were significantly less in the group receiving ropivacaine than in the placebo group . No patients in treatment group received an additional dose of analgesic , whereas two patients in placebo group needed an additional analgesic . Conclusions Our results support the clinical validity of preemptive analgesia , but the timing of intraperitoneal administration of local anesthetic is very important . Only application before creation of the pneumoperitoneum may preempt every neuronal central sensitization
