Q

Hydrocortisone is indicated in:

Prevention of Adrenal crisis in patients who suffer trauma or acute illness and are on long-term steroid therapy, either:
as replacement therapy for adrenal insufficiency from any cause, in long-term therapy at doses of 5+ mg prednisolone, e.g. for immune suppression.

Administer hydrocortisone to:
1. Patients in an established adrenal crisis (IV or IM administration preferable). Ensure parenteral hydrocortisone is given prior to transportation.
2. Patients with suspected adrenal insufficiency or on long-term steroid therapy who have become unwell, to prevent them having an adrenal crisis (IM administration is usually sufficient).
3. Pregnant women with known Addison’s Disease who are in established labour (regular painful contractions).

NB If in doubt about adrenal insufficiency, it is better to administer hydrocortisone.

Can be considered in post ROSC patients that may have arrested due to adrenal crisis.
