Background : The sniffing position, Sellick maneuver (cricoid pressure), and BURP method (backward, upward, and rightward pressure on the thyroid cartilage) are emergency life-saving prehospital tracheal intubation procedures used by technicians trained by anesthesiologists. We evaluated anesthesiologists to determine their knowledge and implementation skills.
Methods : Twenty staff anesthesiologists (M : F, 14 : 6) answered questions about the 3 procedures and then applied the Sellick maneuver to a laryngopharynx model, with a digital scale used to measure compression force.
Results : For all, the percentages of correct answers regarding the sniffing position, Sellick maneuver, and BURP method were 95%, 50%, and 35%, respectively, while only 2 answered correctly regarding the Sellick maneuver recommended force (3kg) . For that maneuver, the measured forces were 4.2±1.9kg (mean ± SD) and 4.5±2.0kg for the right and left hands, respectively, and 4.2±2.1kg and 4.5±1.6kg for males and females, respectively, which were not significantly different between sides and between sexes.
Conclusion : We found confusion regarding the procedures, with the BURP method easily confused with the Sellick maneuver. Unless performed correctly, these emergency techniques may interfere with tracheal intubation. Anesthesiologists who teach emergency life-saving technicians must acquire effective knowledge and skills regarding these procedures.
