Intrathecal Baclofen Pump Refill-Related Cardiac Arrest: A Case Report.

Abstract

We present the case of a 45-year-old male with a history of multiple sclerosis complicated by spasticity and paraplegia, who developed altered mental status and type II respiratory failure requiring intubation on the same day his intrathecal baclofen pump was refilled by his pain physician. Shortly after admission, the patient experienced cardiac arrest four times within two hours until the pump contents were aspirated, and the patient was stabilized. This case report emphasizes the significance of vigilance and prompt recognition of intrathecal baclofen poisoning, which can lead to life-threatening toxicities and withdrawals.
