Heparin vs saline for intermittent intravenous device maintenance in neonates.
The purpose of this study was to determine whether normal saline (NS) is as effective as 10 units heparin/ml saline (HS) in maintaining patency of intermittent intravenous devices (i.v. locks) in neonates. We conducted a prospective, double-blind, randomized study of 118 24-gauge catheters used exclusively as i.v. locks and removed consequent to catheter failure. Subjects were infants, including premature infants, less than one month of age, admitted to a Level II NICU. Catheters were observed for length of patency as well as incidence of phlebitis, occlusion, infiltration, and leaking. There was no statistically significant difference in average duration of patency between NS-flushed catheters and HS-flushed catheters. Phlebitis, occlusion, infiltration, and leaking occurred with equal frequency for both solutions.
