General anesthesia for elective surgery Surgery

Interventions

Participants are randomly assigned in a 1:1 ratio through a computer generated sequence, to receive intubation with Bonfils or C-MAC. After a standardized induction, intubation is done via the retromo

Design outcomes

Primary

Measure	Time frame
Hemodynamic response to intubation is measured using heart rate (HR) and arterial blood pressure (systolic, diastolic and mean arterial blood pressure [MAP]) at induction and every minute for the first five minutes post intubation.	—

Secondary

Measure	Time frame
Duration of intubation (defined as introduction of Bonfils or C-MAC in the oral cavity until confirmation of proper positioning of the endotracheal tube) is measured by a positive capnography reading.	—
