Brief summary

Patients were randomly assigned (1:1) to either a Macintosh laryngoscope group (Macintosh group) or a videolaryngoscope group (Video group).

Detailed description

In the Macintosh group, intubation was performed with a standard curved Macintosh blade. In the Video group, intubation was performed with the assigned videolaryngoscope. If intubation proved difficult with the initially assigned device, anaesthesiologists could switch to the alternative method at their discretion (rescue technique).

Interventions
