| Prompt | [[Prompt::During a major abdominal surgery, a patient receives an injection of pancuronium to facilitate access to the surgical site by paralyzing his abdominal muscles. Several minutes after the injection is administered, the patient's heart rate and blood pressure increase to 135 bpm and 182/99 mmHg. His core temperature begins to increase steadily reaching 41.2 C. Troubled by the unstable vitals, the anesthesiologist administers a second intravenous agent to counteract the effects of the muscle relaxant. The patient's vitals stabilize soon after the second injection and he begins to defervesce.]] |
