Question 1

What is endotracheal intubation and when is it used?

Accepted Answer

Endotracheal intubation is a procedure where a healthcare provider uses a laryngoscope to visualize the vocal cords and guides an endotracheal tube through the glottic opening into the trachea. It secures the airway for controlled ventilation in unconscious patients or those unable to breathe independently, particularly during critical illness or surgery.

Question 2

How does rapid sequence intubation differ from standard endotracheal intubation?

Accepted Answer

Rapid sequence intubation combines pre-oxygenation with rapid administration of sedative and paralytic agents to enable immediate tube insertion, minimizing aspiration risk in high-risk patients. However, it may be avoided in difficult airways because rapid paralysis limits airway visualization, whereas standard intubation allows more controlled assessment of vocal cord anatomy.

Question 3

What are supraglottic airway devices and how do they function?

Accepted Answer

Supraglottic airway devices rest above the vocal cords to enable ventilation without laryngoscopy. The Laryngeal Mask Airway features an inflatable cuff sealing over the glottis, while the I-gel is a non-inflatable gel-based device conforming to pharyngeal anatomy. Both create reliable seals and serve as alternatives when direct intubation is delayed or challenging.

Question 4

How does video laryngoscopy improve airway management outcomes?

Accepted Answer

Video laryngoscopy uses a camera-equipped laryngoscope to provide indirect visualization of vocal cords, offering a clearer view than traditional laryngoscopy. This technique is particularly valuable for patients with anticipated difficult airways, such as those with limited neck mobility or anatomical variations, increasing intubation success rates and reducing airway trauma.

Question 5

What surgical airway interventions are used when intubation fails?

Accepted Answer

Cricothyrotomy is an emergency technique involving an incision through the cricothyroid membrane for rapid airway access when conventional methods fail. Tracheostomy is a more invasive procedure typically performed in controlled settings like operating rooms for long-term airway management, creating a permanent opening in the trachea for prolonged ventilation support.

Question 6

When should fiberoptic bronchoscopy-assisted intubation be considered?

Accepted Answer

Fiberoptic bronchoscopy-assisted intubation is valuable for patients with challenging airways where standard visualization is difficult. A flexible fiberoptic scope inserted through the mouth or nose allows direct visualization of the trachea as the endotracheal tube advances, enabling precise placement in patients with anatomical variations or limited airway access.

Question 7

What steps are involved in performing endotracheal intubation?

Accepted Answer

Endotracheal intubation involves preoxygenation, administering an anesthetic agent, using a laryngoscope to visualize the vocal cords, and inserting a tube into the trachea through oral or nasal passages. This foundational airway management technique secures the airway and allows controlled ventilation in critically ill patients or those undergoing surgery, often as part of cardiopulmonary resuscitation protocols.
