Adrenal Insufficiency in Hypopituitarism — What to Do Before Non-Pituitary Surgery

When a patient with hypopituitarism has concurrent adrenal insufficiency and requires non-pituitary surgery, the inability to mount an adequate endogenous cortisol response to surgical stress demands a structured perioperative plan.

Clinical scenario: Hypopituitarism with adrenal insufficiency in a patient scheduled for non-pituitary surgery — a situation where impaired hypothalamic-pituitary-adrenal axis function makes deliberate glucocorticoid management on the day of surgery essential.

Approach (partial): On the day of surgery, glucocorticoid coverage is adjusted according to the severity and magnitude of the surgical stressor — with the extent of that adjustment differing meaningfully depending on whether the procedure represents minor-to-moderate or major surgical stress. The complete structured regimen is available in the full protocol.

On the day of surgery, we recommend adjusting GC doses according to the severity of illness and magnitude of the stressor.
In cases of minor to moderate surgical stress, we suggest 25–75 mg HC per 24 hours (usually for 1–2 days).
In cases of major surgical stress, we suggest a 100-mg HC iv injection followed by a continuous iv infusion of 200 mg HC per 24 hours (alternatively 50 mg every 6 hours iv or im).
