This prospective and randomized study demonstrates the beneficial effect of intrathoracic intercostal block with bupivacaine on the recovery of pulmonary function after thoracotomy. A significantly (p less than 0.05) better forced expiratory volume was seen in the treated group in the early post-operative period. Similar findings were observed in forced vital capacity. Also, the requirements for analgesics were decreased in the treated group. We believe that intrathoracic intercostal block with bupivacaine when properly utilized can be a good adjuvant in the improvement of pulmonary function after thoracotomy.
这项前瞻性随机研究表明，布比卡因胸内肋间阻滞对开胸术后肺功能恢复具有有益作用。在术后早期，治疗组的用力呼气量显著更好（p<0.05）。用力肺活量也观察到类似结果。此外，治疗组的镇痛药需求量减少。我们认为，正确使用布比卡因胸内肋间阻滞可成为开胸术后改善肺功能的良好辅助手段。
