Comprehensive Strategies for Preoperative Pulmonary Risk Evaluation and Management.

Postoperative pulmonary complications (PPCs) significantly increase morbidity and mortality in surgical patients, particularly those with pulmonary conditions. PPC incidence varies widely, influenced by factors such as surgery type, patient age, smoking status, and comorbid conditions, including chronic obstructive pulmonary disease (COPD) and congestive heart failure. While preoperative pulmonary function tests and chest radiographs are crucial for lung resection surgery, their use should be judiciously tailored to individual risk profiles. Effective risk stratification models, such as the American Society of Anesthesiologists classification, Arozullah respiratory failure index, Gupta Calculators, and Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) model, play a key role in predicting PPCs. Key strategies to diminish PPCs include preoperative optimization of respiratory conditions, smoking cessation, and respiratory rehabilitation. In patients with COPD and asthma, it is crucial to maintain optimal disease control through inhaled therapies, systemic corticosteroids, and tailored preoperative respiratory exercises. Anemia and hypoalbuminemia are significant predictors of PPCs and require meticulous management. The choice and duration of anesthesia also notably influence PPC risk, with regional anesthesia being preferable to general anesthesia when possible. Comprehensive preoperative evaluations and tailored interventions are essential for enhancing surgical outcomes and reducing PPC incidence. Additional studies involving domestic patients are necessary to refine national guidelines for managing those at risk of PPCs.
