Perioperative strategies for the reduction of postoperative pulmonary complications.

Abstract

Postoperative pulmonary complications (PPCs), estimated between 2.0% and 5.6% in the general surgical population and 20-70% for upper abdominal and thoracic surgeries, are a significant factor leading to poor patient outcomes. Efforts to decrease the incidence of PPCs such as bronchospasm, atelectasis, exacerbations of underlying chronic lung conditions, infections (bronchitis and pneumonia), prolonged mechanical ventilation, and respiratory failure, begins with a detailed preoperative risk evaluation. There are several available preoperative tests to estimate the risk of PPCs. However, the value of some of these studies to estimate PPCs remains controversial and is still debated. In this review, the preoperative risk assessment of PPCs is examined along with preoperative pulmonary tests to estimate risk, intraoperative, and procedure-associated risk factors for PPCs, and perioperative strategies to decrease PPCs. The importance of minimizing these events is reflected in the fact that nearly 25% of postoperative deaths occurring in the first week after surgery are associated with PPCs. This review provides important information to help clinical anesthesiologists to recognize potential risks for pulmonary complications and allows strategies to create an appropriate perioperative plan for patients.
