We report an unusual case of endotracheal tube obstruction secondary to alteration of the preoperative fasting period. A patient scheduled for coronary artery bypass grafting had been instructed to take nothing by mouth except scheduled medication with sips of water prior to surgery. Induction of anesthesia and tracheal intubation were accomplished without incident. ⋯ We believe that the mass of gum caused enough deviation of the endotracheal tube to impair ventilation. The safety of preoperative gum chewing and liquid ingestion is discussed. Other incidents of anesthetic problems caused by modification of the traditional preoperative fast are highlighted.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of dexmedetomidine and midazolam sedation and antagonism of dexmedetomidine with atipamezole.
To evaluate the effects of dexmedetomidine, an alpha-2 agonist, as an intravenous sedative drug and the effects of atipamezole, an alpha-2 antagonist, on recovery. ⋯ Atipamezole is an effective antagonist for reversing psychomotor impairment following dexmedetomidine sedation.
