In Vitro Treatment of Extracorporeal Membrane Oxygenation Coagulopathy with Recombinant von Willebrand Factor or Lyophilized Platelets

J Cardiothorac Vasc AnesthPublished Prospective cohort study

Authors' conclusion

Recombinant vWF and lyophilized platelets may help to restore primary hemostasis in ECMO patients.

Study context

Population
Adult ECMO patients and cardiac surgical patients, single academic medical center
Exposure
Untreated ECMO samples vs cardiac surgical patients; ECMO samples treated in vitro with recombinant von Willebrand Factor (vWF) or lyophilized platelets vs untreated
  • Cardiac surgicaln = 10reference
  • ECMO untreatedn = 8
Outcome
Maximum force and thrombus area, untreated ECMO vs cardiac surgical
Follow-up
5 minutes
Methodological detailssingle-centre, in vitro treatment

Main finding

As reported in the abstract

GroupValueThrombus area (median)
ECMO untreatedmedian 39.7 nN0.05
Cardiac surgicalmedian 260.2 nN0.11

Value

ECMO untreatedmedian 39.7 nN
Cardiac surgicalmedian 260.2 nN

Thrombus area (median)

ECMO untreated0.05
Cardiac surgical0.11
  • ECMO untreated vs Cardiac surgical: P = 0.008 — maximum force
  • ECMO untreated vs Cardiac surgical: P < 0.001 — thrombus area
