Changes in the Maximal Inspiratory and Expiratory Pressures after Lung Resection

Abstract

The respiratory muscle function of 22 patients undergoing lung resection was studied. Postoperative ability to expectorate was influenced by preoperative maximal inspiratory (MIP) and expiratory pressures (MEP) which was significantly affected in the patients with difficulty in expectoration. MIP and MEP did not show any remarkable changes after operation. But MIP and MEP decreased in the patients after the pneumonectomy and bilobectomy. The preoperative assessment of MIP and MEP is essential to prevent postoperative pulmonary complications.
