Among children, neonates have the highest incidence of thrombosis due to risk factors such as catheter instrumentation, an evolving coagulation system and congenital heart disease. If normal saline (0.9%) is used, with 50 units heparin in 50mls, the sodium infusion at 0.5ml/hr is 1.8mmol/day (at 0.3ml/hr = 1.08mmol/day). In addition, medications, such as some formulations of sodium heparin, USP, that are frequently used for infants and other critically ill patients may be preserved with benzyl alcohol.

Authors' conclusions: Unfractionated heparin dosing in young infants: clinical outcomes in a cohort monitored with anti-factor Xa levels. Bethesda, MD 20894, Copyright Arterial embolism caused by a peripherally inserted central catheter in a very premature infant: A case report and literature review. The investigators hypothesize that neonatal and pediatric ECMO patients receiving bivalirudin will spend more time at goal anticoagulation and will experience less hemorrhagic and thrombotic complications when compared to patients receiving unfractionated heparin. Pharmacotherapy. 1 Less than 2 weeks ago, as many as 17 infants in a Texas hospital neonatal intensive care unit (NICU) received heparin overdoses.

Background: Heparin is an anticoagulant commonly used in the neonatal population as a means to prevent catheter related occlusion and malfunction by thrombosis (clot). Continuous heparin infusion to prevent thrombosis and catheter occlusion in neonates with peripherally placed percutaneous central venous catheters There is now evidence to show beneficial effect of heparin for preventing complications when used with central catheters to give access to the tiny veins of premature and critically ill babies Francis JL, Groce JB 3rd; Heparin Consensus Group. It is followed by a discussion on dosing of UFH in neonates, limited evidence that forms the basis of published guidelines with justification for a treatment regimen that precludes the use of a heparin loading dose in newborns and monitoring of UFH therapy with currently available tests such as antifactor Xa (anti-Xa) level and activated partial thromboplastin time (APTT). We studied 12 consecutive neonates placed on venoarterial extracorporeal membrane oxygenation (ECMO) in 2004-2005. Prevention and treatment information (HHS). “The concentration of antithrombin can be low in patients on ECMO and is usually low in neonates and critically ill children. Therefore, the anti-Factor Xa level is the ONLY measure of the effect of LMWH therap International Normalized Ratio (INR) The use of antithrombotic therapy in neonates, infants, and children is increasing. Despite limited evidence on anticoagulant treatment in neonates, heparin has become a standard therapy. This small amount of heparin added to the IV fluid has demonstrated that it can prolong the usability of peripherally inserted central venous catheters in neonates … The anticoagulants most commonly used in treatment of neonatal VTE include unfractionated heparin (UFH) and low molecular weight heparin (LMWH). Inpatient+Emergency Pediatric+Neonate Download View … This review focuses briefly on the epidemiology of neonatal thrombosis and the use of UFH in this population.

Options for the management of neonatal TE events include expectant management; nitroglycerin ointment; thrombolytic therapy or anticoagulant therapy, or a combination of the two; and surgery. We used the standard methods of the Cochrane Neonatal Review Group. Given the recent overdoses of infants using heparin, there is concern as to whether heparin should be used in peripherally inserted central venous catheters (PICC). Heparin Type of access matters!!!
