p ULMONARY compliance has been shown to be decreased for a period of several weeks following anesthesia and open-heart operations." 2 This postoperative decrease in compliance is a further change from the low preoperative values seen in patients with heart disease and pulmonary hypertension.34 The prolonged postoperative decrease in pulmonary compliance has not been correlated with changes in lung volumes or in pulmonary gas exchange. The purpose of this study is to relate changes in compliance to other pulmonary functions in the postcardiotomy patient an an attempt to simplify the study of pulmonary function in patients who undergo operations on the heart. METHODSPatients with mitral stenosis were studied before and after cardiac bypass. The subjects were studied in the supine position on four occasions: preoperatively, I to 2 days prior to operation; in the recovery room immediately after operation while breathing continued spon-*Presented at a meeting

“…Decreases in lung resistance are postulated to be related to release of smooth muscle active substances such as prostaglandin E2, pulmonary hypoxia, and lung interdependence with collapse leading to remote bronchial distension. Presence of preoperative pulmonary hypertension in valvular patients, a factor relieved at least partially after surgery, may also contribute to alterations in lung mechanics 135, 147, 148 .…”

The induction and maintenance of anesthesia, surgical requirements, and patients’ unique pathophysiology all combine to create a setting in which our accumulated knowledge of respiratory physiology and lung mechanics take on immediate and central importance in patient management. In this review we will take a case-based approach to illustrate how the complex interactions between anesthesia, surgery, and patient disease impact patient care with respect to pulmonary pathophysiology and clinical decision-making. We will examine two disparate scenarios: a patient with chronic obstructive pulmonary disease undergoing a lung resection, and a patient with coronary artery disease undergoing cardiopulmonary bypass. In each example we will illustrate how important concepts in pulmonary physiology and respiratory mechanics impact clinical management decisions.
