Syringe plunger slides back allowing syringe to de-prime and fill with air if positive pressure is not maintained.3 ml and 10 ml covidien prefilled ns syringes are at issue.After removing the cap and breaking the seal to remove the small air bubble if constant pressure is not held on the plunger, the plunger slides backward when the syringe is held vertical, allowing the syringe to de-prime and fill with air.Nurses have to keep constant pressure on the plunger while attaching to connector/tubing to prevent air from entering the connection and potential bolus to the patient.Cardinal health contacted, in which they acknowledged this occurrence.Plan is to submit 1-2 unused syringes for their evaluation.No harm has occurred that we are aware of, but the potential is great.
