Brief Summary

PLTS-1 is a multicentre, randomized, controlled, pilot trial, using a conventional, parallel group, two-armed design at 2 cardiac surgery centres in Canada. The study is designed to assess the feasibi...

Eligibility Criteria

Inclusion

  • Adult (≥18 years old) patients undergoing elective cardiac surgery with CPB will be eligible for inclusion if they are planned to undergo at least moderately complex surgery or have a preoperative platelet count ≤150,000 x106/L (this is a group at high risk of requiring platelet transfusions post-CPB).
  • Moderately complex index surgery is defined as:
  • repair/replacement of more than one valve;
  • aorta (root/ascending/arch) replacement;
  • any combination of coronary artery bypass grafting, valve repair/replacement, or aorta (root/ascending/arch) replacement; or
  • re-do procedures consisting of a repair or revision of a prior cardiac intervention.

Exclusion

  • Patients will be excluded if cold-stored platelets are not going to be available at the time of surgery or if the patient:
  • has a congenital or acquired hemostatic disorder (including platelet refractoriness due to anti-platelet and anti-human leukocyte antigen \[HLA\] antibodies) and/or requires specially matched platelets (including patients with anaphylaxis to blood due to Immunoglobulin A \[IgA\] deficiency),
  • has known contraindications to heparin, thereby excluding cases where non-reversible anticoagulants (i.e. argatroban) are used,
  • is on warfarin or direct oral anticoagulants (dabigatran, rivaroxaban, apixaban or edoxaban) within 3 days prior to surgery,
  • is on antiplatelet drugs within 5 days prior to surgery (excluding acetylsalicylic acid \[ASA\]),
  • refuses allogeneic blood products,
  • has a known pregnancy,
  • has already enrolled in this study,
  • is enrolled in another interventional clinical trial where routine care and management are altered,
  • has hemodynamic instability defined as critical care admission, vasopressor, or inotrope dependence prior to index surgery, or
  • has pre-operative requirement for, or expected post-operative dependence upon mechanical circulatory support (i.e., intra-aortic balloon pump, ventricular assist device).
