# Individualize postoperative glucocorticoid administration for normal preoperative adrenal function

## STEP 1 — Gather Information
Collect preoperative adrenal function tests (morning cortisol 5–15 µg/dL or ACTH stim peak >18.1 µg/dL), type and duration of surgery, intraoperative glucocorticoid administration, and immediate postoperative vital signs and symptoms.

## STEP 2 — Rule In / Rule Out
Assess for acute adrenal insufficiency: if patient exhibits hypotension, hypoglycemia, or unexplained nausea/vomiting, treat as adrenal crisis (give stress dose GC) and proceed to emergency management; otherwise, continue to individualized postoperative GC plan.

## STEP 3 — Classify or Stratify
Classify surgical stress level: minor/moderate (25–75 mg HC/24h) vs major (>100 mg HC/24h) based on intraoperative findings and postoperative course.

## STEP 4 — Decide
Administer individualized HC regimen: start with stress dose appropriate to surgical stress, then taper over 24–48 hours based on clinical response, aiming to discontinue exogenous GC by postoperative day 2 to allow HPA axis evaluation.

## Clinical Guardrails / Mimics / Pitfalls
Avoid prolonged high-dose GC beyond 48 hours without reassessment, as it suppresses HPA axis recovery; do not rely solely on total cortisol levels if patient is on estrogen therapy (elevated CBG); do not miss signs of adrenal crisis mimicking sepsis or pain.

## Concrete Clinical Example
A 45-year-old woman with normal preoperative morning cortisol of 10 µg/dL undergoes transsphenoidal resection of a nonfunctioning pituitary adenoma (moderate stress). She receives 50 mg HC intraoperatively. Postoperatively, she is normotensive and asymptomatic. She receives 25 mg HC every 8 hours for 24 hours, then 10 mg every 12 hours for another 24 hours, after which GC is stopped and morning cortisol is drawn on postoperative day 2.
