To the Editor The Sellick maneuver (SM) is often used during the rapid sequence induction (RSI) technique to prevent passive regurgitation of gastric contents by occluding the upper esophagus. In a noninferiority, double-blind randomized clinical trial, Birenbaum et al1 reported that for 3472 patients undergoing general anesthesia with RSI, the incidence of aspiration was comparable in patients with and without the application of SM. In addition, the authors further showed that the use of SM may increase the intubation time and difficulty in laryngoscopic exposure.1 Although the findings in this study may provide significant insights into the change of clinical practice, some important issues need to be clarified.
