HLA-DR Expression in Neonates After Cardiac Surgery Under Cardiopulmonary Bypass

HLA-DR Expression in Neonates After Cardiac Surgery Under Cardiopulmonary Bypass

The purpose of this study is to determine how monocyte HLA-DR and other markers of immune function change with time in neonates who underwent cardiac surgery with cardiopulmonary bypasss.

We hypothesize that HLA-DR expression in neonates is predictive of septic complications after cardiopulmonary bypass

Inclusion Criteria:

• Patients aged ≤ 28 days
• Admission after cardiac surgery under cardiopulmonary bypass

Exclusion Criteria:

• Lack of parental consent
