Introduction: Heparinized saline is usually used as a regular flush solution to prevent occlusion of peripheral intravenous locks in neonates but the risks associated with the use of heparin cannot be ignored in these patients. Aim: To assess and compare the efficacy and safety of Heparinized Saline (HS) and Normal Saline (NS) flush solution in neonates. Materials and Methods: A prospective study was conducted for a period of 12 months using 1 unit/ml HS and NS 0.9% solution. The mean number of catheters removed due to nonelective reasons was calculated to evaluate the effectiveness of flushing solutions. To evaluate the safety, the reason for catheter removal was noted and platelet nadir was used to assess the thrombocytopenia. Poisson regression, Pearson Chi-square test and stratified analysis were conducted. Results: Data were analysed from 100 neonates. We found no significant difference between HS and NS flushes in neonates in maintaining the patency of 24 gauge peripheral intravenous locks {rate ratio= 1.12, p-value =0.584}. Gestational age, body weight and site of insertion did not significantly affect the patency. The reasons for removal of catheter were similar in both the groups and majority were due to non-elective reasons. HS group reported more cases of thrombocytopenia that was attributed to sepsis. Conclusion: Standard NS can be considered as an alternative flush in neonates as both the solutions were found to be equally efficacious and safe in our patient group. Factors like gestational age, body weight and site of insertion did not significantly affect the patency.
