A facility reported the perforator did not stop on the second burr hole and continued through the bone and into the dura (plunged).Surgeon felt that added pressure was needed to continue drilling through bone.The procedure was completed with another perforator.No patient injury reported, no medical intervention was required, and the event led to 5 minutes surgical delay.Medtronic drill was used with the perforators.¿this hospital uses a fair amount of these perforators so it may be safe to say user error is not a cause.¿.
