A patient with a known history of malignant hyperthermia presents with laryngospasm. Which medication should be administered?

• A. Succinylcholine
• B. Rocuronium
• C. Amlodipine
• D. Propofol

Answer: (B)

In this scenario, the patient has a history of malignant hyperthermia, a life-threatening condition triggered by certain anesthetic agents, especially depolarizing neuromuscular blockers like succinylcholine. The choice of medication in this case must be one that does not exacerbate the situation or trigger a malignant hyperthermia episode. Rocuronium, as a non-depolarizing neuromuscular blocker, is suitable for treating laryngospasm because it provides muscle relaxation without the risk of triggering malignant hyperthermia. This makes it the preferred choice for intubation or ventilation in patients with a known history of this condition. Other options such as succinylcholine are directly contraindicated in patients with malignant hyperthermia due to the risk of a severe reaction. Amlodipine is a calcium channel blocker primarily used to manage hypertension and has no role in this acute situation. Propofol, while useful for induction and sedation, does not provide the necessary neuromuscular blockade needed to address laryngospasm effectively. Thus, succinylcholine is inappropriate due to the malignant hyperthermia risk, amlodipine is irrelevant to the situation at hand, and propofol does not offer the needed muscle
