Risk Stratification
Diagnostic Studies
-
BMP within 6 months (or more recently if change in clinical status) if known or suspected AI
-
Suspected AI:
-
AM cortisol: if >10 mcg/dl, can rule out AI (Schmidt et al)
-
ACTH-stimulation testing if adequate time to perform testing
-
MANAGEMENT
Indications for Surgical Delay
-
Elective surgery and suspected, undiagnosed adrenal insufficiency
Medication Management
-
Very little evidence is available to guide the best perioperative management of adrenal insufficiency risk - recent review (Groleau et al) and Cochrane review found no evidence of benefit from "stress dose" steroids but too little data to refute the possible benefit
-
Also no good evidence suggesting harm from administration of high-dose glucocorticoids for short periods (though hyperglycemia may occur)
-
ACR/AAHKS guideline for perioperative management of rheumatoid arthritis patients specifically advises against "stress dose" steroids
-
Most recent guidelines are from the Association of Anaesthetists and summarized below:
