About this study

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).
