Brief Summary

Evidence is emerging that those patients with cyanotic pathologies may be more vulnerable to end-organ injury during and after surgery than those patients without, because of compromised cardiopulmonary performances or the proinflammatory state that follows conventional hyperoxic cardiopulmonary bypass. Several clinical and basic studies have identified that controlled oxygenation during the initiation of bypass significantly improved the cardiac adaptation and remodeling capacity than hyperoxic oxygenation strategy among cyanotic patients undergoing tetralogy of Fallot repair, as evidenced by these reduced myocardial gene expression profiles associated with reoxygenation injury. The investigators designed the reoxygenation for pediatric cardiac surgery study to investigate the effect of reoxygenation during cardiopulmonary bypass on clinical outcomes in patients with cyanotic congenital heart disease .

Outcome Measures

Primary Outcomes (1)

  • Pediatric Logistic Organ Dysfunction (PELOD-2) score

    the change in the updated Pediatric Logistic Organ Dysfunction (PELOD-2) score (PELOD-2 score; range, 0 to 33 points, with higher scores indicating more severe organ dysfunction)

    up to 30 days

Secondary Outcomes (1)

  • low cardiac output syndrome

    up to 30 days

Study Arms (1)

Reoxygenation

After one minute of full bypass, fraction of inspired oxygen (FiO2) in liberal group was increased at increments of 0.1 per minute to reach a FiO2 target of 40%-80% adjusted reoxygenation to maintain PO2 in the range of 250mm Hg-300 mm Hg or more during the bypass.

Procedure: Reoxygenation

Interventions

ReoxygenationPROCEDURE

After one minute of full bypass, fraction of inspired oxygen (FiO2) in conservative group was increased at increments of 0.1 per minute to reach an FiO2 target of 40% that was adjusted to maintain an arterial PO2 in the range of 250 mm Hg or less during the bypass, while FiO2 in liberal group was increased at increments of 0.1 per minute to reach a FiO2 target of 80% adjusted to maintain PO2 in the range of 300 mm Hg or more, on the basis of arterial PO2 level measured via a point of care blood gas analyzer.

Study Population

The infants and young children aged 1 months to 18 years were eligible for enrolment in this study if they had echocardiography confirmed congenital heart diseases.

You may qualify if:

  • The operation-naive infants and young children aged 1 months to 18 years old were eligible for enrolment if they were indicated for undergoing anticipated radical repair of cyanotic congenital heart disease with cardiopulmonary bypass.

You may not qualify if:

  • The chromosomal defects, airway and parenchymal lung disease, immunodeficiency, blood transfusion during the current admission, previous cardiac operation, or the opinion of the treating physician that randomization would not be in the best interest of the patient (lack of equipoise)
