TYPE OF DEVICE/MANUFACTURER

N/A

ACTION TAKEN

The fault occurred 10 mins before the end of bypass during de-airing of the heart after mitral surgery.
The surgeon informed of fault and second perfusionist brought into theatre for support.
Unable to reach calculated flow, blood gases were monitored closely to ensure adequate perfusion.
Patient tolerated enforced low flow levels.
De-airing of the heart performed using clamps to control blood outflow from the pump unit.
Patient weaned from bypass safely again using clamps.
Pump rebooted once safely off bypass which cleared the fault.
Critical incident reported at local level.
Heart lung machine removed from service and colleagues informed of incident.

RESPONSE FROM MANUFACTURER

Sorin engineer called to investigate and replace the faulty unit. Thought to be a fault with the drive unit not the control panel.
