About this trial
Romiplostim has demonstrated its efficacy and good tolerance in multiple indications. If the efficacy of Romiplostim is confirmed in this population, thrombocytopenic patients will be able to undergo cardiac surgery, which is generally life-saving, without prior thrombocytopenia.
Patients included in the study will be hospitalized within 15 days of the first administration of the study treatment and will be closely monitored clinically and biologically for at least 10 days after surgery. The occurrence of an adverse event can therefore be quickly detected and managed.
Collectively, "Patient Blood Management" strategies are mainly focused on the management of preoperative anemia. If positive, this study will enrich the therapeutic arsenal available for optimizing patients in preparation for major surgery. As no major collective complications are expected, the collective benefit/risk ratio also appears favorable.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adult patients with no upper age limit,
Scheduled cardiac surgery with cardiopulmonary bypass,
Patients with preoperative thrombocytopenia strictly <150,000/mm3
Surgery performed with a blood recovery system using centrifugation (Cell Saver type) or equivalent,
Disqualifiers
Inability to administer the first injection of Romiplostim or Placebo within 10 days prior to surgery,
Cardiac surgery without cardiopulmonary bypass,

Tangential filtration blood recovery system (i-SEP SAME® type) planned for intraoperative use or absence of intraoperative blood recovery system due to investigator choice or availability issues,
