A Severe Baclofen Intoxication Mimicking Post-Hypoxic Encephalopathy: Wait and See!

BACKGROUND

A severe baclofen intoxication is a potentially life-threatening condition. It is associated with coma and can cause brainstem reflexes to disappear, simulating a brain death-like condition. When given intensive supportive care and time, patients can recover without residual neurological damage.

CASE REPORT

We present a case of a patient with known spastic cerebral palsy who was found unresponsive with no signs of breathing. He was brought to the Emergency Department, intubated, put on the ventilator, and hemodynamically stabilized. Brainstem reflexes were absent and he appeared brain dead. During the secondary survey, an intrathecal baclofen pump was found at his left lower abdomen, with a swelling next to it. A baclofen intoxication was suspected. He was admitted to the Intensive Care Unit, and after 72 h of supportive care complete neurological recovery was achieved. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Systemic baclofen intoxication can simulate a brain death-like condition. There is no reliable correlation between baclofen serum levels and central nervous system depression in case of an intoxication. It is important for emergency physicians to recognize a baclofen intoxication as a possible cause of coma and absent brainstem reflexes. Recuperation is spontaneous and can follow within days without residual damage. Because these patients may be brought in after a period of apnea or cardiopulmonary resuscitation, focus may be on post-hypoxic encephalopathy considerations instead of a possible baclofen intoxication.
