[Epidural morphine and buprenorphine for postoperative pain relief after hepatectomy].
Postoperative pain relief with epidural morphine and buprenorphine was studied in 33 patients following hepatectomy. Morphine 2mg or buprenorphine 0.06mg in 10ml of normal saline was administered through an epidural catheter inserted at the Th10-11 or L3-4 interspace. Morphine injected at the lumbar level, as well as that injected at the thoracic level produced excellent and long-lasting (20.8 +/- 8.6 hours) pain relief. Respiratory rate decreased significantly following epidural morphine at the L3-4, but PaCO2 did not change. Buprenorphine injected at the thoracic level produced good and long-lasting (22.6 +/- 9.9 hours) pain relief, although buprenorphine injected at the lumbar level produced incomplete analgesia. The epidural administration of morphine 2mg at L3-4 or buprenorphine 0.06mg at Th10-11 may be recommended for postoperative analgesia following hepatectomy.
