A Vancomycin-Heparin Lock Solution for Prevention of Nosocomial Bloodstream Infection in Critically Ill Neonates With Peripherally Inserted Central Venous Catheters: A Prospective, Randomized Trial

Prophylactic use of a vancomycin-heparin lock solution markedly reduced the incidence of CRBSI in high-risk neonates with long-term central catheters and did not promote vancomycin resistance but was associated with asymptomatic hypoglycemia. The use of an anti-infective lock solution for prevention of CRBSI with long-term intravascular devices has achieved proof of principle and warrants selective application in clinical practice.
