Evaluation of Pro-Inflammatory Leukocyte Activity in Patients Undergoing Cardiac Surgery
Boston Children's Hospital
Summary
The goal of this proposal is to prospectively collect data from a series of 200 patients (all ages) undergoing complex cardiac surgical procedures involving cardiopulmonary bypass (CPB) to: 1. Measure the number of blood activated circulating monocytes before, during and after cardiac surgery and serum GABA and pro-inflammatory cytokine levels 2. Understand the correlation between GABA and inflammatory cytokines (and/or activated monocytes) and 3. Assess the correlation between thrombosis and monocyte activation in patients undergoing cardiac surgery under CPB and at risk of thrombosis.
Description
Often when people undergo heart surgery, they are placed on cardiopulmonary bypass (CPB). Sometimes clotting of the blood occurs during and after heart surgery with CPB, which can lead to multiple complications. In order to try to avoid abnormal/excessive clotting that may lead to complications, it is important to understand the specific causes of why the blood sometimes clots abnormally during and after heart surgery. Currently, tests looking at how the blood clots (coagulation assessment) are usually performed as standard laboratory testing during and after surgery. However, these tests are…
