Endotracheal Intubation: Essential Airway Management Technique

Jun 17,2025

Endotracheal intubation is a critical medical procedure that establishes a secure airway by inserting a flexible plastic tube through the mouth or nose into the trachea. Primarily used in general anesthesia, ICU care, and emergency medicine, this life-saving technique ensures adequate oxygenation and ventilation while protecting the airway from aspiration.

Endotracheal Intubation: Essential Airway Management Technique

Endotracheal intubation is a critical medical procedure that establishes a secure airway by inserting a flexible plastic tube through the mouth or nose into the trachea. Primarily used in general anesthesia, ICU care, and emergency medicine, this life-saving technique ensures adequate oxygenation and ventilation while protecting the airway from aspiration.

The procedure requires precise anatomical knowledge and technical skill, with key landmarks including the epiglottis and vocal cords. Standard equipment includes laryngoscopes (Macintosh/Miller blades), endotracheal tubes with inflatable cuffs, stylets, and confirmation devices like capnography. Modern variations incorporate video laryngoscopy for difficult airways.

Clinical applications span routine surgical cases to emergency scenarios like cardiac arrest or respiratory failure. Proper execution demands strict adherence to aseptic technique, correct tube size selection, and immediate confirmation of placement. While highly effective, potential complications include dental trauma, esophageal intubation, and ventilator-associated pneumonia.

Continuous monitoring and proper tube maintenance are essential post-intubation. As a fundamental component of advanced life support, endotracheal intubation remains the gold standard for definitive airway control in critical care settings worldwide.
