Late one evening, in Open Heart Recovery, my seventy-five-year-old patient’s temperature shot up from 98 to 103. I gave her Tylenol suppositories, double-checked the blood she was getting and called her surgeon. Dr. Vance instructed me to repeat the Tylenol, add intravenous steroids, then quickly hung up the phone. He needed some sleep after performing cardiac bypass surgery all day and on-call.
Mrs. Smith’s elevated temperature both worried and puzzled me. She might be having an allergic reaction or malignant hyperthermia.
