What should an anesthesia provider do first when Malignant Hyperthermia is diagnosed?

Administer intravenous fluids
Discontinue anesthetic gas and hyperventilate with 100% O2
Call for emergency assistance
Direct the surgical team to close the procedure immediately

The correct answer is: Discontinue anesthetic gas and hyperventilate with 100% O2

When Malignant Hyperthermia (MH) is diagnosed, the first and most critical action an anesthesia provider should take is to discontinue the anesthetic gas and hyperventilate the patient with 100% oxygen. This response is essential because MH is a life-threatening reaction usually triggered by certain anesthetic agents, most notably volatile anesthetics and succinylcholine. Discontinuing these agents halts the progression of the hypermetabolic state associated with MH. Providing 100% oxygen also supports the patient's respiratory function and helps to mitigate the effects of the elevated carbon dioxide levels that commonly occur during an MH crisis. It addresses hypoxia and maintains oxygen delivery to vital organs as the healthcare team mobilizes further interventions. While calling for emergency assistance, administering intravenous fluids, and directing the surgical team to close the procedure are important subsequent steps in the overall management of MH, they should follow the immediate cessation of triggering anesthetics and ensuring sufficient oxygenation. Through this immediate action, the provider aims to stabilize the patient during this critical situation.
