Hyperangulated vs. Macintosh blades for obstetric intubation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-site feasibility study at Mount Sinai Hospital in Toronto comparing two video laryngoscope blade designs for the first attempt at tracheal intubation during urgent or emergency cesarean deliveries under general anesthesia. Patients are assigned to a blade type based on time-block clusters (four 4-month periods), with one-month washouts between periods; clinicians may deviate if patient safety requires. Data on airway variables and perioperative factors will be collected from electronic records by a trained research assistant. The design aims to reflect real-world workflow while minimizing contamination from rapid decision-making in obstetric emergencies.
