Comparison of Direct and Indirect Laryngoscopes in Vomitus and Hematemesis Settings: A Randomized Simulation Trial

Table 1

Tracheal intubation success rates for McL, AWS, and McGRATH in normal, hematemesis, and vomitus settings.

	Normal simulation; (successful/total)	Hematemesis simulation; (successful/total)	Vomitus simulation; (successful/total)	value
McL	17/17	15/17	17/17	0.125
AWS	17/17	10/17	12/17	<0.001
McGRATH	17/17	16/17	17/17	0.361
value	0.978	0.021	0.003

AWS, Pentax-AWS Airwayscope; McGRATH, McGRATH MAC; McL, Macintosh laryngoscope.
Numerator: number of participants who were successfully intubated.
