Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Bleeding rate (quantified by the number of packed red blood cells transfused in relation to the duration of ECMO therapy)

    The bleeding rate will be quantified by the number of packed red blood cells in relation to the duration of ECMO therapy. This duration may vary and cannot be predicted. Thus, we will calculate the required number of packed red blood cells i.e. per week.

    up to 6 months

Secondary Outcomes (18)

  • number of bleeding incidences and severity of bleeding (bleeding grades)

    up to six months

  • Number of Clotting Events

    up to six months

  • Function of the membrane oxygenator

    up to six months

  • Number of changes of the membrane oxygenator relative to the duration of ECMO therapy

    up to six months

  • Inflammation specific biomarkers (i.e. C-reactive protein, blood counts, reticulated platelets, etc.)

    Time points: Immediately prior to initiation of ECMO, 24, 48 and 72h after initiation of ECMO, then twice a week until end of ECMO therapy, up to 12 months

  • +13 more secondary outcomes

Study Arms (2)

Alprostadil

EXPERIMENTAL

Placebo

PLACEBO COMPARATOR

heparin (dose adjusted to aptt 50-60s) + 0.9% sodium chloride infusion, continuously, start within 24h of initiation of ECMO therapy and end at the end of ECMO therapy
