In patients with obesity, which is a consideration in preoperative planning?

• A. Increased airway and cardiopulmonary risk
• B. Diminished need for ventilation strategies
• C. Lower risk of wound complications
• D. No impact on airway management

Answer: (A)

Obesity heightens perioperative risk because excess body weight alters airway anatomy and lung mechanics. Increased neck tissue and pharyngeal crowding make airway management more difficult and raise the risk of difficult ventilation or intubation, while reduced chest wall compliance and lower functional residual capacity increase the chances of hypoxemia and atelectasis during anesthesia. Obesity is also commonly linked with obstructive sleep apnea and cardiovascular disease, which together elevate perioperative cardiopulmonary risk and necessitate careful planning of ventilation strategies, analgesia, hemodynamic management, and postoperative respiratory support. Wound complications are more common in obesity, making optimization and postoperative care critical.
