Data assessment of the trial. Number of attempts (left) and time to successful intubation (right) compared by intubation method (n = 15 per group). With the endoscopic technique, significantly less intubation attempts were necessary (*: P = 0.043). Successful video-endoscopic intubation took more time per attempt until adequate ventilation was completely established (***:P < 0.001) but showed less desaturation episodes. Statistical analyses were performed using the Mann-Whitney U test
