Clinical Trial Summary

General objective of the research project: To evaluate the alterations of systemic microvascular reactivity during cardiopulmonary bypass (CPB), in children submitted to cardiac surgery for repair of congenital heart defects.


Clinical Trial Description

• Specific objectives:

- To test the usefulness of skin laser Doppler flowmetry monitoring (LDPM) in the non-invasive evaluation of endothelium-dependent microvascular reactivity during CPB in children.

- To investigate whether skin LDPM could be proposed as a clinical monitoring of tissue perfusion during CPB in pediatric cardiac surgery.

- To investigate the effects of different anesthetic agents on microvascular reactivity during CPB.

- To investigate the effects of cardiovascular and vasoactive drugs used during CPB on microvascular reactivity.

- To evaluate the correlation of microcirculatory alterations observed during CPB with classical markers of tissue perfusion and oxygenation, including plasma lactate levels.

- To evaluate the correlation of microcirculatory alterations observed during CPB with markers of systemic inflammation, including pro- and anti-inflammatory cytokines.

- To evaluate the correlation of microcirculatory alterations observed during CPB with the plasma bioavailability of nitric oxide. ;
