Twenty patients undergoing a posterolateral thoracotomy for lung resection or a nonpulmonary procedure were divided into four groups. Group 1 was the control group. Patients in Group 2 had an intercostal nerve block at the time of closure. ⋯ It is concluded that bedside spirometry is a simple and reliable technique to assess postoperative changes in ventilatory mechanics due to pain. The pain that follows posterolateral thoracotomy can be substantially decreased with a continuous intercostal nerve block. Anterolateral thoracotomy is notably less painful than posterolateral thoracotomy and should be considered the approach of choice for patients with decreased pulmonary reserve who undergo uncomplicated pulmonary resection.
