the effect of different sellick's maneuver on laryngoscopic view and intubation time

background: sellick's maneuver (cricoid pressure) may make laryngoscopic view and tracheal intubation more difficult. this study compared the different techniques of cricoid pressure (cp) regarding to the laryngoscopic view and time to intubation. methods: in142 anesthetized patients, 4 types of cp was randomly applied; a) one-handed cp using thumb, index and middle fingers, b) one-handed cp using index and middle fingers, and the heel on the sternum, c) technique a with another hand below the neck, d) technique c with a pillow below the neck. results: there was significant difference in the laryngoscopic view changes. the view was better in group a, c, d and b, respectively. mean intubation time did not show significant difference. conclusion: one-handed cp using thumb, index and middle fingers can provide the best views at laryngoscopy without significant effect on time to intubation. key words: sellick's maneuver, laryngoscopic view, intubation time, tracheal
