Last AANA revision: 2023

Reaffirms that any facility administering volatile anesthetics or succinylcholine must have an MH cart with sufficient dantrolene (Ryanodex preferred) immediately available, and that all anesthesia providers must be trained on the MH crisis algorithm.

Key points

1.MH cart accessible within minutes — sufficient dantrolene for ~36 mg/kg of an average adult
2.Cooling supplies (ice, cold IV NS), bicarb, calcium, insulin, dextrose, glucose monitor
3.MHAUS hotline phone number posted: 1-800-MH-HYPER
4.Annual mock MH drill recommended
5.Document susceptibility on patient's chart + recommend genetic counseling for family
