FDA: Implantable Infusion Pump May Malfunction During MRI
The US Food and Drug Administration (FDA) has received reports of serious adverse events, including patient injury and death, associated with the use of implantable infusion pumps in the magnetic resonance environment, the agency said today in a safety communication.

The reports include medication dosing inaccuracies, including overinfusion or underinfusion or unintended bolus, and mechanical problems with the pump, such as motor stalling and the pump not restarting after MRI.

The magnetic resonance environment presents "safety hazards for patients with implantable infusion pumps. Only implantable infusion pumps labeled as MR Conditional may be used safely within an MR environment, and only under the specified conditions of safe use," the FDA said.
