Platelet Activation Markers in Pediatric Cardiac Surgery

February 29, 2012 updated by: Aarti Sharma, Weill Medical College of Cornell University

Effect of Cardiopulmonary Bypass on Platelet Activation Markers Such as Platelet Factor 4 and Transforming Growth Factor B, in Pediatric Cardiac Surgery

In this study the focus will be on correlating the levels of platelet activation markers (proteins that are released when blood cells are activated)to the duration of cardiopulmonary bypass, temperature during cardiopulmonary bypass and the weight of the patient.

Detailed Description

This research is being done because we would like to learn more about platelet dysfunction in children undergoing cardiopulmonary bypass.

It has been an established fact that cardiopulmonary bypass causes dysfunction in platelets. Activation of platelets during cardiopulmonary bypass is implicated as being a major factor in causing platelet dysfunction.

For all participants, approximately 3.15 ml of blood will be collected in special tubes called CTAD tubes, before and after cardiopulmonary bypass (6.30ml in total). This amount of blood draw is well within the guidelines of NIH (National Institute of Health).

Enzyme-linked immunosorbent assay (ELISA) will be performed using this plasma to make quantitative assessment of Platelet factor 4 and Transforming growth factor beta.
