Data are presented as median (interquartile range) except for successful weaning and acute renal failure on ECMO. MO, membrane oxygenator; ICU, intensive care unit; RBC, red blood cells; FFP, fresh frozen plasma (1 FFP contains 230 ml plasma); PC, platelet concentrate (1 PC contains 250 ml and 2–4×1011 thrombocytes); ARF, acute renal failure.
