Abstract

BACKGROUND: Epidural buprenorphine has been shown to reduce the anesthetic and analgesic requirements during the perioperative period. The goal of this study is to see whether epidural buprenorprhine reduce the dose of fentanyl infusion for anesthetic management and postoperative pain control and shorten the duration of postoperative ventilatory support and endotracheal intubation in open heart surgery patients. Method: Total 50 patients who underwent the open heart surgery were included for the study. General anesthesia was maintained with a nitrous oxide (2 L/min)-oxygen (2 L/min)-isoflurane (0.5~1.5 %). In control group additional anesthetic requirement is supplemented with intermittent intravenous injection of fentanyl. In buprenorphine group initial loading dose of 0.3 mg of epidural buprenorphine followed by continuous epidural infusion (20 microgram/hr) and additional anesthetic requirement was supplemented with intravenous fentanyl.
RESULTS
The total dose of fentanyl requirement was significantly lower in buprenorphine group than in control group. The duration of ventilatory support and endotracheal intubation were significantly shorter in buprenorphine group than in control group. The duration of ICU stay was not different between two groups.
CONCLUSIONS
Epidural buprenorphine reduced the anesthetic requirement and postoperative pain and shortened the duration of postoperative ventilatory support and endotracheal intubation. Therefore epidural buprenorphine can be an reasonable alternative for an adjunctive with general anesthesia and postoperative pain control.
