Timeframe: From withdrawal of general anesthesia until the return of normal pharyngoesophageal function, assessed up to 40 minutes.

Population: Thirty-two patients, 18 women and 14 men, ages ranging from 20 to 76 years were studied.

Correlation of the return of normal pharyngoesophageal function with other markers generally used by Anesthesia staff to indicate a safe time for removal of endotracheal tubes.
