Design outcomes
Primary
| Measure | Time frame |
|---|---|
| First-attempt intubation success rate using video laryngoscopy with either the steerable bougie or the CMAC stylet.Timepoint: At the time of the intubation attempt (intraoperative). | — |
Secondary
| Measure | Time frame |
|---|---|
| Total number of intubation attempts required for successful tube placement.Timepoint: Total number of intubation attempts required for successful endotracheal tube placement, assessed at the time of confirmation of tracheal intubation by continuous waveform capnography.;Time taken from insertion of the laryngoscope to confirmation of endotracheal tube placement.Timepoint: Time to intubation was defined as the interval from insertion of the laryngoscope blade into the oral cavity to confirmation of endotracheal tube placement by continuous waveform capnography.;Operator-rated ease of use of the intubation deviceTimepoint: Operator-rated ease of use of the intubation device, assessed immediately after completion of the intubation procedure.;Requirement for laryngeal manipulation during intubationTimepoint: Requirement for external laryngeal manipulation during intubation, assessed during the intubation attempt.;Incidence of complications, including hypoxia, esophageal intubation, dental trauma, and hemodynamic instabilityTimepoint: Incidence of complications, including hypoxia, esophageal intubation, dental trauma, and hemodynamic instability, assessed during the intubation procedure and in the immediate post-intubation period. | — |
