## **Core Concept**
The use of steroids during surgery is crucial for patients who are on long-term steroid therapy. Steroids suppress the hypothalamic-pituitary-adrenal (HPA) axis, which can lead to adrenal insufficiency during stress, such as surgery. This requires supplementation of steroids to prevent acute adrenal crisis.

## **Why the Correct Answer is Right**
The correct approach for a patient on steroid therapy undergoing surgery involves administering stress-dose steroids. Normally, the adrenal glands increase cortisol production in response to stress. However, in patients with HPA axis suppression due to exogenous steroid use, this response is blunted. Administering stress-dose steroids helps to mimic the body's natural response to stress, preventing potential hypotension, shock, and even death. The typical regimen involves giving hydrocortisone, often in doses such as 100 mg hydrocortisone every 8 hours.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because simply continuing the usual dose of steroids may not provide sufficient coverage for the stress of surgery. The body's demand for cortisol increases during surgery, and the usual dose might be inadequate.
- **Option B:** Stopping steroids abruptly before surgery could lead to an adrenal crisis, especially if the patient has been on long-term steroid therapy. This option does not address the need for stress-dose steroids.
- **Option C:** While monitoring vital signs and adjusting fluid and electrolyte balance is crucial, this option does not directly address the need for steroid supplementation during surgery.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that patients on long-term steroid therapy require stress-dose steroids during surgery to prevent adrenal insufficiency. A commonly used regimen is hydrocortisone 100 mg IV every 8 hours. It's also important to note that the need for supplementation generally applies to patients who have been on steroids for more than 3-4 weeks.

## **Correct Answer:** . Hydrocortisone supplementation
