Pulmonary aspiration.

This case focuses on pulmonary aspirations during the perioperative period by asking the question: What is the incidence and clinical significance of pulmonary aspiration during the perioperative period based on the predictive potential of common clinical findings? This study showed that pulmonary aspiration among surgical patients was associated with increasing American Society of Anesthesiologists (ASA) physical status and emergency procedures. Patient with clinically apparent pulmonary aspiration who do not develop signs or symptoms within 2 hours in the immediate postoperative period are unlikely to have respiratory sequelae.
