Abstract

Bleeding and thrombosis frequently occur in pediatric patients with extracorporeal membrane oxygenation (ECMO) therapy. Until now, most patients are anticoagulated with unfractionated heparin (UFH). However, heparin has many disadvantages, such as binding to other plasma proteins and endothelial cells in addition to antithrombin, causing an unpredictable response, challenging monitoring, development of heparin resistance, and risk of heparin-induced thrombocytopenia (HIT). Direct thrombin inhibitors (DTIs), such as bivalirudin and argatroban, might be a good alternative. This review will discuss the use of both UFH and DTIs in pediatric patients with ECMO therapy.

Summary

This review discusses pediatric ECMO anticoagulation, noting that unfractionated heparin has limitations including unpredictable response and heparin-induced thrombocytopenia, and considers direct thrombin inhibitors such as bivalirudin and argatroban as alternatives.

Why This Matters for Hirudotherapy

This review examines anticoagulation strategies in pediatric ECMO, discussing the disadvantages of unfractionated heparin (UFH)—including unpredictable response, heparin resistance, and risk of heparin-induced thrombocytopenia (HIT)—and the potential of direct thrombin inhibitors (DTIs) such as bivalirudin and argatroban as alternatives. Bivalirudin (formerly Hirulog) is a synthetic peptide anticoagulant designed partly on the C-terminal sequence of hirudin, the anticoagulant of the medicinal leech (Maraganore et al., 1990); this paper studies the drug, not leech therapy.
