Answers are grounded in this paper and cite their sources.
Pulmonary function recovery after general anesthesia is significantly delayed (beyond 5 days) in thoracic and upper abdominal surgeries compared to lower abdominal and peripheral surgeries, necessitating prolonged respiratory care.
Background: After general anesthesia, decrease of functional residual capacity and lung compli. ance, ventilationj perfusion imbalance. and transpulmonary shunting can provoke hypoxemia during postoperative periods. Diaphragmatic dysfunction may be the main cause of these ph ysiological abnormalities. Thus, we evaluated the change of pulmonary functi on after general anesthesia according to the operative sites, which could suggest clinical course and critical period of respiratory care of postoperative patients.
