Baby had a peripheral arterial line in the left saphenous, which was being transduced and had 0.45 normal saline w/heparin 1unit/ml running through it at 1ml/hr.Blood draw was performed via arterial line.Art line flushed after blood draw.Nurse noticed no blood back into the line when nurse left the bedside to send the labs.<1min later nurse came back to the bedside, glanced in the baby's bed and saw blood back into the line and onto the chux that holds the transducer.Nurse immediately check all connections and found a loose connection to the distal port, next to the flush port.Once connections were tightened, chux was weighted and 2ml blood loss noted.Md was notified and no intervention was ordered.Nurse noted that they had to retighten the same connection on at least one other patient recently.
