???Silent??? Regurgitation During General Anesthesia

Abstract
“Silent” regurgitation occurs more frequently than is realized by the anesthesiologist or surgeon. A strong direct relationship between the anesthetic agent, patient position, and operative site has been shown. Regurgitation is easily overlooked unless specific means of detection are used. A more aggressive approach should be taken to remove gastric secretions from the oropharynx before cuff deflation and extubation. Tracheal intubation, especially in high-risk patients, may appreciably reduce postanesthetic complications from silent regurgitation and occult aspiration.
