Changes in lymphocyte subsets after cardiac surgery in children.

Unlabelled: Children undergoing cardiopulmonary bypass (CPB) operations have an increased risk of developing severe infections. Impairment of the immune system may contribute to the development of sequelae such as capillary leaks, pulmonary dysfunction and auto-immune reactions. The objective of this study was to investigate the impact of cardiac surgery with CPB on the immune system of infants and young children.
