title: [Evaluation of postoperative pain relief by infiltration of bupivacaine or epidural block after laparoscopic cholecystectomy].
abstract: We compared the analgesic effect of bupivacaine infiltration into surgical wounds with that of epidural block after laparoscopic cholecystectomy (LC). Forty-five patients (ASA physical status I-II) for LC were randomized into three groups (n = 15 in each group). Patients received only general anesthesia (Group C), received infiltration of 0.5% bupivacaine into the surgical wound before surgery combined with general anesthesia (Group L), or received epidural anesthesia combined with general anesthesia (Group E). Postoperative pain was assessed using visual analogue scale (scale: 0-10) at 1, 2, 6 and 12 hours after the operation, the need for additional supplemental analgesics, and the cost of anesthesia. Visual analogue scale in Group C at 1, 2, or 6 hours was significantly greater than that of Group L and E. The number of patients who needed supplemental analgesics was 9 in Group C, 5 in Group L, and 2 in Group E. The cost of pharmaceutical and anesthetic practice of Group E was more expensive than Group L and C. In conclusion, infiltration of bupivacaine combined with general anesthesia is an effective and economical method of postoperative pain relief.
