The continuous monitoring of the oxygen venous saturation is an early alert on serious disorders in oxygen balance and allows timely therapeutical interventions. Objective: To identify the relation between oxygen saturation of the blood extracted from the superior vena cava and from the pulmonary artery. Method: An observational, descriptive, analytical and prospective study was conducted in 72 children, programmed for elective cardiac surgery and the written informed consent and the approval of Ethics Committee. After induction of general anesthesia a catheter was passed into the superior vena cava. At the end of surgical correction of the oxygen venous saturations in the above vein were determined and by direct puncture of the pulmonary artery. Data were statistically processed determining the means and the standard deviations (SD) of both samples. The Student t test was applied. Authors considered the existence of a difference or association if the associated likelihood to test was lower than 0,05 (p <0,05). Results: The oxygen saturation of samples took in both locations, has not a significant statistical difference (p > 0.05). Conclusions: The continuous monitoring of the oxygen venous saturation in the superior vena cava is correlated with that of the pulmonary artery in this series.
