History of Present Illness

A 35-year-old African-American man with a history of alcohol abuse presented to Emergency Department after he was found down. He was seen by a passerby on the street who witnessed the patient fall with a possible convulsive event. He was brought in by ambulance and was unconscious and unresponsive.

PMH, SH, and FH

The patient had a history of prior ICU admission in Yuma with septic shock secondary to a dental procedure requiring a tracheostomy in 2018. He also had a history of alcohol intoxication requiring an ED visit about 10 years ago and history of sickle cell trait. Per chart review, the patient took no home medications. Further history was unable to be obtained due to the patient's condition.

Physical Examination

On arrival the patient had a core temperature of 41°C, systolic blood pressure in the 70s-80s, heart rate of 185, respiratory rate of 19, and an oxygen saturation of 99% on room air. Patient was not able to answer any questions.

On examination, the patient had a Glascow Coma Scale of 6 (no eye response, no verbal response, and normal flexion). Pupils were 4 mm bilaterally and reactive to light. The remainder of his HEENT was unremarkable with no meningismus reported. Pulmonary exam showed rapid, shallow breathing and coarse breath sounds with no crackles, wheezes, or rhonchi. Heart examination showed tachycardia with no murmurs or extra heart sounds. Abdomen was soft and nondistended. Skin was diaphoretic without cyanosis, clubbing, or edema.

Laboratory, Radiology and EKG

Initial laboratory testing was significant for a potassium level of 7.5 mmol/L, creatinine level of 1.96 mg/dL which was increased from baseline of 0.93 mg/dL, CK level of 2344 U/L, AST 93 U/L, ALT 62 U/L, and total bilirubin 2 mg/dL. Lactic acid was within normal limits. His EKG showed sinus tachycardia. His urinalysis was cloudy with protein and blood. His head CT was negative for any intracranial abnormalities or bleed.

Hospital Course

He was given 3 L of IV fluids, empiric vancomycin and piperacillin/tazobactam, and his hyperkalemia was managed with calcium gluconate, insulin and glucose. He was intubated for airway protection due to his shallow breathing and GCS of 6, started on pressor support, and was admitted to the ICU.

Based on the initial findings, what is the most likely cause of the patient’s presentation? (Click on the correct answer to be directed to the second of six pages)

1. Acute encephalitis
2. Delirium tremens
3. Heatstroke
4. Malignant hyperthermia
5. Septic shock
