Prospective observational study evaluating the C-MAC Video Stylet for awake tracheal intubation: a single-center...

Area of Science:

• Anesthesiology
• Airway Management
• Medical Devices

Background:

• Awake tracheal intubation is the standard for managing difficult airways.
• The C-MAC Video Stylet combines features of rigid stylets and flexible optical scopes.
• Its feasibility for awake intubation in difficult airways requires evaluation.

Purpose of the Study:

• To assess the feasibility of awake orotracheal intubations using the C-MAC Video Stylet.
• To evaluate the device's effectiveness in patients with known or predicted difficult airways.

Main Methods:

• Prospective observational study involving three experienced anesthesiologists.
• 12 awake oral intubations performed per anesthesiologist on adult patients.
• Primary outcome: overall intubation success; Secondary outcomes: attempts, time, sequelae, difficulty rating.

Main Results:

• 97% overall intubation success rate within 45 seconds.
• 80% first-attempt success rate achieved in 37 seconds.
• 92% of patients would opt for the procedure again; median difficulty VAS 3.

Conclusions:

• The C-MAC Video Stylet shows potential as a valuable tool for visualized awake oral intubation.
• It appears suitable for managing difficult airway situations.
• The device may offer a safe and effective option for airway management.
