Initial management steps for myxedema coma include which of the following?

• A. Airway, fluid resuscitation, passive rewarming, IV levothyroxine
• B. Immediate tracheostomy
• C. High-dose steroids alone
• D. Antibiotics only

Answer: (A)

In myxedema coma, the first priority is rapid stabilization of life-supporting functions while beginning thyroid hormone replacement. This means securing the airway and providing ventilation because severe hypothyroidism often depresses respiration and mental status, requiring airway protection or assisted ventilation. Circulation is addressed with cautious IV fluids to support blood pressure and correct potential hypovolemia or hyponatremia. Temperature is managed with passive rewarming methods (like blankets) to gradually raise core temperature without aggressive external warming that can destabilize hemodynamics. Crucially, thyroid hormone replacement should be given intravenously, since oral absorption is unreliable in coma; IV levothyroxine acts to rapidly reverse the hypothyroid state. Because adrenal insufficiency can accompany severe hypothyroidism, a stress-dose steroid such as hydrocortisone is given until adrenal function is confirmed. Treat any precipitating infection if present, but antibiotics alone do not address the underlying endocrinologic emergency. This combination of airway/ventilation support, circulatory and temperature management, IV thyroid hormone replacement, and steroids when indicated represents the proper initial approach.
