Catheter lock solution comprising sodium citrate and benzyl alcohol

Abstract

This disclosure generally relates to catheters, methods of enhancing the patency of an intravascular catheter and compositions, methods, devices and kits relating to the infusion of a catheter lock solution into an indwelling catheter. Disclosed compositions, methods, devices and kits aid in diminishing the effects of microbial infection in catheters and occlusion of the catheters. A representative lock solution includes about 10% sodium citrate and about 1.5% benzyl alcohol. The solution has a density approximating the density of blood for retention of the solution in a catheter during the lock period.
