The customer reports that they had trouble flushing the umbilicus was oozing while port was running.When we started port two, the pump repeatedly alarmed occluded patient side.The umbilical tie was loosened and then attempted to flush port one and it did the same.Previously that night we had trouble with the umbilical artery spraying blood.It did not have a catheter at the time.The artery had to be stitched but was still pulsating.The original uvc was in at 5 cm.The baby was 4500 grams so it is quite possible that between her size and the force of her blood flow, 5 cms just wasn't enough.Another nurse observed what appeared to be a hole in the line.
