CRYPTICS (Cardiopulmonary Bypass Surgery) - Clinical Trial

What is the Purpose of this Study?

We are doing this study to find out if an experimental product called cryopreserved platelets (CPP) can help control the bleeding that happens during and after cardiopulmonary bypass surgery. We want to see how well this product works in comparison to the standard therapy that is used to control bleeding during surgery, which is liquid stored platelets (LSP).

What is the Condition Being Studied?

Cardiopulmonary Bypass Surgery

Who Can Participate in the Study?

Adults who are scheduled or referred to have cardiopulmonary bypass surgery at Duke.

- Get a random assignment (like a coin flip) to either receive CPP or LSP during your surgery

- Have blood draws

- Have a follow-up phone call with the study team 30 days after your surgery
