What special airway considerations exist for an obese patient undergoing general anesthesia?

• A. Obese patients have easier airway; use standard intubation.
• B. Preoxygenation is unnecessary.
• C. Plan includes awake or early airway management strategies.
• D. Higher risk of difficult mask ventilation and intubation; plan includes preoxygenation, awake or early airway management strategies, and possibly advanced airway devices.

Answer: (D)

Obesity changes airway dynamics and oxygen reserve, making airway management during general anesthesia more hazardous. The reduced functional residual capacity, higher oxygen consumption, and excess soft tissue in the upper airway increase the likelihood of difficult mask ventilation and difficult intubation. Desaturation can occur rapidly during apnea, so a robust plan is essential.

The best approach emphasizes thorough preoxygenation to buy time if ventilation becomes difficult. It also prioritizes awake or early airway management strategies when a difficult airway is anticipated, so the patient’s spontaneous breathing can be preserved while securing the airway. Being prepared with advanced airway devices and techniques—such as video laryngoscopy, fiberoptic scopes, supraglottic devices, and bougies—along with a clear rescue plan, improves safety. Proper positioning (ramped alignment) and having a skilled team ready are also key components of a safe plan.

That combination explains why this option is the most appropriate: it directly addresses the increased risk, ensures oxygenation safety, and lays out concrete strategies to manage a potentially difficult airway.
