I got to admit I've never heard of those drugs, but I went and looked them up. Malignant hyperthermia I've heard of before and I already have a protocol to deal with that. I do recognize that the patient not coming out of anesthesia is pretty significant and would start with the ABCs and inform the ED before we even left in case they need more info from the CRNA.Here's what really shocking... Most of the replies in this thread are from the gunners. How many run of the mill medics would shrug and bag/vent this guy to the local ED. I'd bet you could ask 10 medics and 8 of the 10 would have not heard of MH other tha obliquely, would have no idea what sevo, dantrolene or sugammadex is or where to even start with this patient. (Do same day surgery centers stock dantrolene?)
