Preparing to use the flexible fiber-optic laryngoscope

Area of Science:

• Anesthesiology
• Medical Education
• Airway Management

Background:

• Flexible fiber-optic laryngoscopy is a valuable intubation technique.
• Effective teaching methods are crucial for anesthesiology trainees.
• Previous methods may have limitations in educational settings.

Purpose of the Study:

• To describe and evaluate a current method for teaching flexible fiber-optic laryngoscopy.
• To assess the safety and efficacy of this teaching technique in a clinical setting.

Main Methods:

• A review of a current flexible fiber-optic laryngoscopy technique was conducted.
• Over 1,000 patients undergoing general endotracheal anesthesia for renal lithotripsy were intubated orally.
• Patients received thiopental sodium and succinylcholine, with continuous monitoring.

Main Results:

• The flexible fiber-optic technique was successfully used for intubation in the majority of patients.
• Three obese patients experienced rapid desaturation, requiring instructor intervention.
• All patients were ultimately intubated successfully, with rapid resolution of desaturation after oxygenation.

Conclusions:

• Oral flexible fiber-optic laryngoscopy and intubation can be taught safely.
• Thiopental sodium and succinylcholine are suitable agents for this teaching method.
• Adherence to specific guidelines ensures the safety and efficacy of the teaching technique.
