Abstract
A solution is described that can be used to maintain the patency of an I.V. catheter or other vascular access device having a lumen. The density and osmolarity of the solution are adjusted so that the density and osmolarity of the solution are approximately equal to the density and osmolarity of whole blood in a patient. The solution can be injected into the lumen of the vascular access device to prevent blood from the patient from entering the lumen.
