Table 1 Video laryngoscopy performed on a mannequin with a pre-formed vs a conventional endotracheal tube

Outcome measures	Pre-formed tube	Conventional tube	P value
Intubations, n	60	60
Time to intubate in s, average (range)	22 (15-42)	12 (7-15)	0.008^a
First-pass success, n (%)	57 (95)	49 (81)	0.03^a
Torque > 8 PSI, n (%)	5 (8)	39 (65)	0.001^a

^aP < 0.05. PSI: Pounds per inch.
