Clear, Colorless, Odorless
A patient is found with a suicide note in a car and brought in by ambulance. He complains of headache, malaise, nausea, and dizziness. He is too altered to give much more history. His skin looks a little red. Vital signs are: HR 70, BP 110/60, RR 16, O2 saturation 99% on room air, temperature 37. Cardiac biomarkers (CKMB and troponin) are elevated. A CT of the head, taken 16 hours later, is shown above. Weeks later, the patient still has some cognitive deficits, personality changes, and neurologic defects.
Challenge: What diagnostic test should the emergency department order?
