NCT06332547

Brief Summary

This prospective, randomized controlled study is aimed to figure out suitable transfusion threshold in patients undergoing cardiac valve surgery under cardiopulmonary bypass(CPB). Patients are randomly assigned to restrictive and liberal transfusion group and receive blood transfusion during and after surgery. Compare primary and secondary outcomes of two groups.

Outcome Measures

Primary Outcomes (1)

  • A composite of postoperative morbidity and mortality

    The composite components are postoperative mortality, infectious morbidity(wound infection, septicemia, or sepsis), ischemic event(myocardial infarction, stroke, renal infraction, bowel infraction )

    Postoperative 6 months

Secondary Outcomes (11)

  • Rate of reoperation

    Postoperative 6 months

  • Length of ICU Stays

    From date of the end of operation until the date of discharging from ICU or date of death from any cause, whichever comes first, assessed up to 2 months.

  • Length of Postoperative Hospital Stay

    From date of discharging from ICU until the date of discharging from hospital or date of death from any cause, whichever comes first, assessed up to 2 months.

  • Number of Blood Transfusion

    From date of beginning of surgery until the date of discharging from hospital or date of death from any cause, whichever comes first, assessed up to 3 months.

  • Duration of mechanical ventilation

    From date of the end of surgery until the date of discharging from ICU or date of death from any cause, whichever comes first, assessed up to 2 months.

  • +6 more secondary outcomes

Study Arms (2)

Restrictive transfusion strategy

ACTIVE COMPARATOR

Restrictive transfusion strategy: Blood transfusion triggers of Hb valve less than 6.0g/dL or Hct value less than 18% during CPB, Hb valve less than 7.0g/dL or Hct value less than 21% in ICU or general ward. Red blood cell transfusion will be given when Hct values fall below 18% or Hb fall below 6.0g/dL during CPB, 2 units RBC transfusion will be administered. In ICU or general ward after surgery, RBC transfusion will be given when Hct values fall below 21% or Hb fall below 7.0g/dL during CPB, 2 unit RBC transfusion will be administered. Following administration of the 2 units transfusion a repeat HCT or Hb is performed, if their values greater than threshold, no further transfusions will be administered, or will be received 2 units RBC again.

Other: Restrictive Transfusion Strategy

Liberal Transfusion Strategy

ACTIVE COMPARATOR

Liberal Transfusion Strategy: Blood transfusion triggers of Hb valve less than 8.0g/dL or Hct value less than 24% during CPB, Hb valve less than 10.0g/dL or Hct value less than 30% in ICU or general ward. Red blood cell transfusion will be given when Hct values fall below 24% or Hb fall below 8.0g/dL during CPB, 2 units RBC transfusion will be administered. In ICU or general ward after surgery, RBC transfusion will be given when Hct values fall below 30% or Hb fall below 10.0g/dL during CPB, 2 units RBC transfusion will be administered. Following administration of the 2 units transfusion a repeat HCT or Hb is performed, if their values greater than threshold, no further transfusions will be administered, or will be received 2 units RBC again.

Other: Liberal Transfusion Strategy

Interventions

Blood transfusion at HCT less than 21% or Hb less than 6.0g/dL during CPB, at HCT less than 21% or Hb less than 7.0g/dL in ICU or general ward after surgery

Restrictive transfusion strategy

Blood transfusion at HCT less than 24% or Hb less than 8.0g/dL during CPB, at HCT less than 30% or Hb less than 10.0g/dL in ICU or general ward after surgery

Liberal Transfusion Strategy
