Study summary

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

Read the 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).

What researchers measure

Primary outcomes

  1. determine whether modern technologies such as videolaryngoscopy shorten intubation time.

    measurment of intubation time in seconds

    Time frame: 1 day

Secondary outcomes

  1. complications

    included the incidence of failed intubation with the assigned device, the number of intubation attempts, and the use of an introducer (bougie). Any intubation attempt that failed could be rescued with the alternative device.

    Time frame: 1 day
