RESUMEN
ObjectiveTo evaluate the effect and safety of dezocine and sufentanil in intravenous analgesia for postoperative pain. Methods60 patients with ASA Ⅰ～Ⅲ,underwent general anaesthesia operation were divided into two groups randomly,with 30 cases for each group:dezocine 0.6mg/kg and sufentanil 0.6mg/kg was applied to PCIA in group A and B.PCIA was administered with subsequent bolus of 1 ml with lockout time 15 minutes and background infusion of 2ml/h.The analgesic effect was evaluated by VAS,BCS and Ramsay at 1、2、4、12、24、48 hours after operation.The changes of vital sign were also assessed. ResultsThere was no significant difference between two groups in analgesia effect(all P＞0.05)and adverse reaction incidence rate(P＞0.05). ConclusionThe effect of dezocine in intravenous analgesia for postoperative pain could be as satisfaction as that of sufentainyl.
