DIAGNOSTIC SIGNIFICANCE OF DETERMINING OXYGEN SATURATION VALUE IN FULL-TERM NEWBORN INFANTS

Aim. To determine the standard values of oxygen saturation and the causes of its fall in full-term newborn infants for improvement of diagnostic possibilities of pulse oximetry in neonatological practice. Materials and methods. 543 full-term newborn infants underwent pulse oximetry, 226 - echocardiographic examination. Results. Oxygen saturation standards in newborn infants were developed. It was shown that presence of fetal communications as well as small muscular defect of interventricular septum is not accompanied by decrease in its value and increase in gradient of indices between the upper and the lower extremities. The following factors lowering oxygen saturation in full-term newborn infants without organic cardiovascular diseases were detected: complicated course of pregnancy and labor, polycythemia, declined contractile ability of myocardium. Growth of gradient of indices between the upper and lower extremity was observed in case of mild cerebral ischemia and in infants with high weight and body length indices at birth.
