Study summary

The purpose of this study is evaluate goal-directed therapy with continuous central venous saturation compared to standard therapy in children undergoing cardiac surgery.

Read the detailed description

Pediatric patients undergoing cardiac surgery are at risk for adverse clinical outcomes due a inadequate tissue perfusion. Recent studies have been demonstraded which the monitorization of continuos central venous saturation could be benneficial. There is evidence that monitoring continues venous oxygen saturation (ScvO2) can be beneficial in patient outcomes, guided by ScvO2 therapy has been associated with improved outcomes in resuscitation of critically ill patients with sepsis and after congenital heart surgery complexa. The early detection and treatment of tissue hypoxia can prevent morbidity and mortality. tissue hypoxia may be a result of the imbalance between supply (DO2) and oxygen consumption (VO2). If the fault supply, oxygen consumption is maintained by increased oxygen extraction resulting in decreased central venous oxygen saturation

Study arms

  • Active comparator
    Goal-directed therapy

    Patients randomized to this group will be monitoring by continuous central venous oxygen saturation. Central venous oxygen saturation will be targeted higher than 65% in non-cyanogenic patients and 55% in cyanogenic.

    Other: Continuous central venous oxygenation monitoring

  • Other
    Standard protocol

    The control group will keep the standard therapy.

    Other: Standard protocol

Interventions

  • OtherContinuous central venous oxygenation monitoring

    Central venous oxygen saturation will be targeted higher than 65% in non-cyanogenic patients and 55% in cyanogenic. * First, isotonic crystalloid, 10 up to 20 mL/kg, will be administered in boluses to achieve continuous central venous oxygen saturation higher than 65% in non-cyanogenic and 55% in cyanogenic. * Second, if not achieved with fluid administration, will be targeted by initiating and titrating inotropics (dobutamine or milrinone). If the mean arterial pressure is lower than 50 mm Hg will be associated epinephrine. * If the ScvO2 is lower than 65% in non-cyanogenic and 55% in cyanogenic and the hemoglobin was lower than 8g/dl, red blood cells (20mL/Kg) will be transfused to achieve a hemoglobin level of at least 8g/dL.

  • OtherStandard protocol

    The control group will keep the standard therapy to achieve mean arterial pressure higher than 50mmHg, central venous pressure 8 to 12 mmHg, urinay debit higher than 0,5ml/kg/h, hemoglobin higher or equal than 8g/dL, arterial oxygen saturation higher or equal than 92% in non-cyanogenic and 80% cyanogenic, central venous oxygen saturation higher or equal than 65% in non-cyanogenic and 55% in cyanogenic.
