What pregnancy-related factors should be considered during airway management?

• A. Pregnancy-related airway edema, hemodynamic changes, and altered respiratory mechanics
• B. No changes in airway management needed
• C. Always use uncuffed tubes exclusively
• D. Avoid rapid sequence induction

Answer: (B)

Pregnancy changes airway management because anatomy and physiology shift in ways that raise both the difficulty of securing the airway and the risk if oxygenation falters. Mucosal edema from increased vascularity and hormones makes the upper airway more fragile and easier to swell further during airway manipulation, so you should anticipate a potentially difficult airway and have advanced airway devices and a careful plan ready. Respiratory mechanics also shift: functional residual capacity is reduced while oxygen consumption is higher, so a patient desaturates much faster during any apnea. That means thorough preoxygenation is essential and apnea time should be minimized, with a plan for rapid, decisive airway control. The cardiovascular system is expanded in volume and vascularity, increasing the risk of bleeding and edema with airway instrumentation, so gentle technique and readiness to manage edema-related issues are important. Aspiration risk is higher due to relaxed gastric sphincter tone and pressure from the gravid uterus, which pushes toward approaches that protect the airway during induction, often favoring rapid sequence induction to minimize passively venting gastric contents. Positioning matters too—left uterine displacement improves venous return and ventilation. In short, pregnancy-specific factors necessitate adapting airway strategy rather than assuming no changes are needed.
