We studied the effect on postoperative pain relief of continuous epidural infusion of analgesics with an infusion balloon container. Of the 46 patients undergoing thoracotomy at our hospital 24 patients (Group A) received continuous infusions of diluted buprenorphine with saline with an infusion balloon container and 22 patients (Group B) were infused every 12 hours. The average pain score in Group B was 1.79±0.24, significantly higher than that in Group A, 1.62 ± 0.19 (p =0.01). The pain score was especially higher in Group B than in Group A from morning to evening on the 2nd post-operative-day. The frequency of administration of supplemental analgesics was higher in Group B than in Group A. We conclude that continuous epidural infusion of analgesics with an infusion balloon container is more effective than intermittent infusion for postoperative pain relief after thoracic surgery.
