MedSchool Forums USMLE QBank A 48-year-old woman with a history of pituitary surgery and irradiation is scheduled for elective surgery. She currently requires replacement thyroxine, hydrocortisone, estrogen, and progesterone. In the perioperative period you should treat her with which of the following?
  1. Glucose infusion
  2. Increased hydrocortisone
  3. ACTH infusion
  4. Increased estrogen
  5. Increased thyroxine
Spoiler for Answer:
Increased hydrocortisone. Sudden withdrawal of corticosteroids could be fatal if the patient could not mount a stress-response (tachycardia and cortisol-mediated increase in blood-pressure) to the surgery.
