Heparin is employed in neonates for several reasons:
1. Prevention of Catheter-Related Thrombosis: Neonates often require central venous catheters for fluid and medication administration. Heparin helps to prevent clot formation in these catheters.
2. Management of Thromboembolic Disorders: Conditions like neonatal stroke or deep vein thrombosis may require anticoagulation therapy.
3. Extracorporeal Membrane Oxygenation (ECMO): Heparin is used to prevent clot formation in the ECMO circuit, which is vital for the life support system that provides prolonged cardiac and respiratory support.
