PGE1 as Additive Anticoagulant in ECMO-Therapy

Brief description of study

Bleeding complications and thromboembolic complications are frequent during extracorporeal membrane oxygenation (ECMO). Retrospective data suggest that platelet inhibition using prostaglandins, in this case PGE1, may reduce thromboembolic complications without increasing the bleeding risk. This randomized, double-blind trial aims to investigate the effects of PGE1 on bleeding risk, thromboembolic complications and the function of the ECMO.

Detailed Study Description

Prostaglandins may inhibit platelet activation via the P2Y1 ADP receptor. Platelets may contribute to thromboembolic complications and coagulation activation during ECMO therapy. Retrospective data suggest that treatment with PGE1 may serve beneficial by reducing the amount of heparin needed for inhibition of coagulation activation, and by reducing the thromboembolic risk without increasing the risk of bleeding.

Inhibition of platelets via PGE1 (Alprostadil) may be interesting in this setting, because, in contrast to other platelet inhibitors, it has a very short half-life and platelets remain susceptible for activation by more potent agonists (i.e. thrombin, ADP). Thus, although reducing the contribution of platelets to coagulation activation, it may not affect safety of participating subjects.

This randomized, double-blind, placebo controlled trial will investigate whether treatment of patients with ECMO therapy proves beneficial.
