A 5 year old healthy child is undergoing strabismus surgery with a Laryngeal mask airway in place. Thirty minutes into the procedure, his heart rate is 60 bpm, blood pressure is 90/60 mmHg, and oximeter shows 98% saturation. The next step in management is

**Core Concept**
Strabismus surgery in children often involves general anesthesia, and maintaining hemodynamic stability is crucial. The patient's symptoms and vital signs suggest a possible vagal response or vasovagal syncope due to the stress of surgery and the Laryngeal mask airway.

**Why the Correct Answer is Right**
The correct answer involves administering a medication to counteract the potential vagal response. This is likely due to the release of acetylcholine, which causes a decrease in heart rate and blood pressure. The use of atropine is a common practice in such scenarios to prevent bradycardia and hypotension.

**Why Each Wrong Option is Incorrect**
**Option A:** Administering oxygen is the correct action when there's a concern for hypoxia, but in this case, the oximeter shows 98% saturation, indicating adequate oxygenation.
**Option B:** Using a cardiac stimulant like epinephrine might be considered in cases of cardiac arrest, but it's not the first line of treatment for vagal response or vasovagal syncope.
**Option C:** Increasing the anesthetic depth might worsen the situation by further depressing the cardiovascular system.

**Clinical Pearl / High-Yield Fact**
Atropine is often used in pediatric anesthesia to prevent bradycardia and hypotension due to vagal responses, especially during strabismus surgery or other procedures that may cause stress.

**Correct Answer:** A. Atropine

✓ Correct Answer: B. Inform surgeon, administer atropine
