AbstractTo evaluate the effects of continuous extrapleural intercostal nerve block on post-thoracotomy pain and pulmonary complications, a randomized, double-blind, placebo-controlled study was conducted on 80 patients undergoing elective thoracotomy for pulmonary (n = 47) or oesophageal (n = 33) procedures. In patients who received continuous bupivacaine infusion, the requirement for intramuscular opiate and rectal diclofenac was less, the score on a visual linear analogue pain scale lower and recovery of pulmonary function more rapid than in saline-infused controls. Postoperative pulmonary complications occurred in 35% of the saline group, but only 10% of the patients with bupivacaine infusion (p < 0.01). In patients with chronic obstructive airways disease (COAD), the incidence of postoperative pulmonary complications was 54.5% in the saline group and only 4.5% in the bupivacaine group (p < 0.01). Among the patients without COAD there was no significant intergroup difference in such complications. We conclude that continuous extrapleural intercostal nerve block is effective for post-thoracotomy analgesia and reduces pulmonary complications of thoracotomy in patients with COAD.
