In pediatric airway management, which condition would most strongly contraindicate the use of etomidate for induction?

• A. Asthma
• B. Croup
• C. Allergic rhinitis
• D. Septic shock

Answer: (D)

The key idea is that the safety of an induction drug in critical illness depends not only on how it sedates but also on how it affects the body’s stress response. Etomidate is appreciated for keeping blood pressure relatively stable during induction, but it has a notable drawback: it can transiently suppress adrenal cortisol synthesis by inhibiting 11β-hydroxylase. In septic shock, the body’s ability to raise cortisol is crucial to maintain vascular tone and to respond effectively to vasopressors. If etomidate blunts this adrenal response, patients in shock may experience worsened hypotension and poorer perfusion, making septic shock a strong contraindication for using etomidate.

Airway conditions like asthma, croup, or allergic rhinitis don’t carry this specific adrenal-related risk, so they don’t present the same contraindication. They may influence airway management strategy, but they don’t inherently contraindicate etomidate in the way septic shock does.
