Comparative analysis evaluates locking mechanisms in patients with vascular access devices, suggesting normal saline may be as effective as heparin.
Encounters (N = 2,908) during six months of heparin locking were compared to encounters (N = 3,239) during six months of normal saline locking. Data demonstrated minimal variance between locking with normal saline compared to heparin.
