As the criterion "first-attempt intubation success" is increasingly selected to be a main endpoint in large randomized controlled trials, we aimed to determine whether first-attempt success in intubation is indeed associated with fewer intubation-related complications than first-attempt failure. Among the 1844 intubations available, there were 1440 (78%) successful first attempts, 275 (15%) successful second attempts, 88 (5%) successful third attempts and 41 (2%) of the intubations necessitated four or more attempts.
