Postoperative Transfusions following Administration of Delayed Cold Stored Platelets vs. Room Temperature Platelets in Cardiac Surgery: A Retrospective Cohort Study.

In adults undergoing cardiac surgery, delayed cold-stored platelets were associated with higher postoperative transfusion utilization and lower platelet counts compared to room temperature stored platelets without differences in clinical outcomes. The use of delayed cold-stored platelets in this setting may offer a viable alternative when facing critical platelet inventories but is not recommended as a primary transfusion approach.
