入选标准

  • Patients greater than or equal to 18 years of age undergoing elective cardiac surgery with cardiopulmonary bypass.
  • Patients must that have a calculated protamine dose greater than 250 mg based on standard 1:1 initial heparin to protamine dosing calculation.

排除标准

  • Patients who are under 18 years of age or pregnant.
  • Patients undergoing emergency surgery (ASA class E).
  • Patients with known coagulation disorders.
  • Patients requiring circulatory arrest or deep hypothermia.
  • Patients who have not had the appropriate interruption in coumadin, direct oral anticoagulants or non-aspirin antiplatelet agents.
  • Patients on pre-operative intravenous unfractionated heparin infusions.
  • Patients ineligible for heparin administration due to known adverse reactions including allergy or heparin induced thrombocytopenia or known heparin resistance.
  • Patients who are unable to provide informed consent in the form of a signature.
  • History of adverse reaction to protamine.
  • Have any condition that, in the opinion of the investigator, will compromise the well-being of the patient or the study, or prevent the patient from meeting or performing study requirements.

研究组 & 干预措施

Fixed Dose Protamine group

Experimental

Participants in the group will receive a one time dose of 250 mg Protamine to reverse heparin during the standard cardiopulmonary bypass management during cardiac surgery.

干预措施: Protamine fixed dose (Drug)

Ratio Dose Protamine Group

Active Comparator

Participants in the group will receive a ratio dose of Protamine in a 1mg per 100 units of heparin ratio to reverse heparin during the standard cardiopulmonary bypass management during cardiac surgery.

干预措施: Protamine ratio dose (Drug)

结局指标

主要结局

Activated Clotting Time

时间窗: up to 4 hours (after cardiopulmonary bypass surgery)

Activated clotting times will be measured using standard coagulation monitor

次要结局

  • Additional Protamine Dosing(Up to 4 hours)
  • Chest Tube Output(Up to 24 hours)
  • Count of Participants Receiving Red Blood Cell Transfusion(Up to 4 hours)
