Brief Summary
Acute normovolemic hemodilution (ANH) is part of our current protocol to decrease post-operative bleeding and homologous blood transfusions post cardiopulmonary bypass. Blood is drawn from our patients pre-bypass after obtaining the arterial line and administered back to the patient after separation from cardiopulmonary bypass (CPB) and reversal of heparin with protamine. In our practice we noticed some variability in the impact of ANH on postoperative bleeding; with some patients appearing to show more hemostasis after separation from CPB than others. This is a prospective study to find out if there is an optimal time period that guarantees the largest amount of functioning platelets and what is the best practice for drawing and storing of ANH to guarantee the largest amount of functioning platelets.

Outcome Measures
Primary Outcomes (2)
Time to Platelet Aggregation as Measured Using Collagen-epinephrine (EPI)
The membrane of the cartridges are coated with collagen and epinephrine (EPI) inducing a platelet plug to form which closes the aperture.
Just prior to re-transfusion, assessed up to 5 minutes
Time to Platelet Aggregation as Measured Using Collagen-Adenosine (ADP)
The membrane of the cartridges are coated with collagen and adenosine diphosphate (ADP) inducing a platelet plug to form which closes the aperture.
Just prior to re-transfusion, assessed up to 5 minutes
Study Arms (1)
Acute normovolemic hemodilution (ANH)
Patients undergoing acute normovolemic hemodilution (ANH) as part of their cardiac surgery.
Interventions
Blood is drawn from our patients pre-bypass after obtaining the arterial line and administered back to the patient after separation from cardiopulmonary bypass (CPB) and reversal of heparin with protamine.
Eligibility Criteria
Patients undergoing open-heart surgery who will be having acute normovolemic hemodilution (ANH) as part of their surgery.
You may qualify if:
- All patients undergoing cardiac surgery on CPB and are determined to be suitable for ANH by the cardiac team during the huddle process per our standard protocol.
You may not qualify if:
- Patients who are undergoing cardiac surgery on CPB who are determined not to be suitable candidates for ANH by the cardiac team during the huddle process per our standard protocol.
