Comprehensive strategies for preoperative pulmonary risk evaluation and management.

Abstract

Postoperative pulmonary complications (PPCs) significantly increase morbidity and mortality in surgical patients, particularly those with pulmonary conditions. The incidence of PPCs varies widely, influenced by surgery type, patient age, smoking status, and comorbidities like chronic obstructive pulmonary disease (COPD) and congestive heart failure. Preoperative pulmonary function tests and chest radiographs, while critical for lung resection surgery, should be selectively used based on individual risk factors. Effective risk stratification models, including ASA classification, Arozullah Respiratory Failure Index, Gupta Calculators, and ARISCAT model, aid in predicting PPCs. Key strategies to reduce PPCs involve preoperative optimization of pulmonary conditions, smoking cessation, and respiratory rehabilitation. In COPD and asthma patients, maintaining optimal disease control through inhaled therapies, systemic corticosteroids, and preoperative respiratory exercises is crucial. Anemia and hypoalbuminemia are notable predictors of PPCs, warranting careful management. The type and duration of anesthesia significantly impact PPC risk, with regional anesthesia preferred over general anesthesia when feasible. Comprehensive preoperative evaluation and tailored interventions are essential to improve surgical outcomes and reduce PPC incidence. Further study involving domestic patients is needed to refine national guidelines for managing patients at risk of PPCs.
