NCT03041974

Brief Summary

During storage, red blood cells (RBCs) undergo changes collectively termed "Storage lesions". these changes may have an impact of the outcomes of transfused patients. One of these changes is the release of microparticles by RBCs and other blood cells types. The aim of the study is to (1) quantify red cell- and platelet-derived microparticles in RBC concentrates, and (2) evaluate the impact of transfused microparticles (MPs) on survival and post-transfusion complications in critical care patients participating in the ABLE trial (ISRCTN44878718).

Sampling MethodNon-Probability Sample
Study Population

The patients included in the study are the patients enrolled, by french centers, in either arms of the ABLE trial.

You may qualify if:

  • Have had a request for a first red cell unit transfusion in the Intensive Care Unit (ICU), and
  • Have an anticipated length of invasive and/or non-invasive continuous positive airway pressure (CPAP) or bi-level positive airway pressure (BIPAP) mechanical ventilation of at least 48 hours once enrolled, as estimated by the attending physician

You may not qualify if:

  • less than 18 years of age
  • previously enrolled in the ABLE study
  • has already been transfused with red cells during the current hospitalisation
  • has an obvious terminal illness documented in the medical record with a life expectancy of less than 3 months
  • has undergone routine cardiac surgical care
  • decision to withdraw/withhold some critical care had been made
  • brain dead
  • no red cells with a storage time of 7 days or less available in the blood bank that cannot be transported from the blood supplier
  • Who require more than 1 unit of uncross-matched red cells
  • With a known objection to blood transfusions
  • With autologous blood donations
  • Who pose difficulties in securing blood products (rare blood groups), and who are difficult to match
