Abstract
Introduction: Near infrared spectroscopy allows non-invasive assessment of cerebral and systemic oxygen saturation on the management of congenital cardiac surgery.
Objectives: To know the median values of oxygen cerebral and systemic in newborns who undergo cardiac surgery.
Materials and methods: Observational prospective study from June 2009 to February 2010. The studied variables were gestational age, type of congenital heart disease, inotropical support, mean arterial pressure, oxygen extraction, cerebral and systemic oxygen saturation, central venous pressure, left atrial pressure, diuresis, level of lactate, oxygen saturation, FiO2, postoperative complications and need for extracorporeal membrane oxygenation (ECMO).
Results: 22 patients were studied. Transposition of great arteries was the most frequent cardiac disease, median gestational age was 38+4 weeks. Mean values of cerebral saturation was 62% ± 9% and systemic saturation 59% ± 14%. Median values for the variables were: median blood pressure 49,9 ± 4mmHg; oxygen extraction 40 ± 11; lactate 2,3 ± 1mmol/L; paO2 72 ± 9mmHg; FiO2 37 ± 13%; central venous pressure 7 ± 2mmHg; left atrial pressure 6 ± 3mmHg. Dopamine being used in all cases at 8mcg/kg/min and milrinone in 21 cases at 0,9mcg/kg/min. Epinephrine was used in 17 at 0,08mcg/kg/min. In 21 cases furosemide was used at 0,65mg/kg/hr, with diuresis of 4,9mL/Kg/hr. Five required ECMO.
Conclusions: Cerebral and systemic oxygen saturation supplies easily acquired data that provides information on the haemodinamical situation in the postoperative neonatal cardiac surgery. It is of special importance to consider the tendency of the values thanks to its continue recording.
