[Analgesic effects of epidurally administered fentanyl for postoperative pain relief--comparison with buprenorphine].
We did a retrospective study on 177 patients after upper and lower abdominal surgery, and compared the efficacy of epidural administration of fentanyl and that of buprenorphine for postoperative pain relief. In fentanyl (F) group, 73 patients received fentanyl 0.1 mg with saline 8 ml epidurally after operation, followed by a constant rate infusion of 0.025 mg.hr-1 for 18-24 hrs. In buprenorphine (B) group, 104 patients, received buprenorphine 0.2 mg with saline 9 ml epidurally. After upper abdominal surgery, 33 patients (76.7%) in F group and 27 patients (52.9%) in B group obtained satisfactory analgesia (P < 0.05). The difference of the degree of analgesia after lower abdominal surgery was not significantly different in both groups. Respiratory depression occurred in 19 patients in B group and 5 patients in F group (P < 0.05). It is concluded that epidural fentanyl delivered by continuous infusion offers a significant advantage compared with epidural buprenorphine for postoperative pain relief following upper abdominal surgery.
