Summary
Brief summary
A phase 3 randomized partial blind storage duration ranging study in patients undergoing complex cardiac surgery that will compare the transfusion of cold stored platelets to standard room temperature stored platelets. The primary objective is to establish that cold stored platelets have a non-inferiority (or superiority) to room temperature platelets.
