[Analysis of mean differences for acid-base balance parameters in blood from umbilical arteries and veins of newborns with perinatal hypoxemia].
Arterio-venous differences in acid-base parameters of umbilical vessels blood using Nickelsen and Weber method and SPSS/PC+ computer's program were calculated. The mean differences are dependent on fetal metabolism, umbilical blood flow and placental gas exchange. Arterio-venous differences--normal or increased for pH, PCO2, PO2 and SO2 are valuable diagnostic indicators of accurate gas exchange while decreased values of these differences should predict placental dysfunction. Small differences are signs of chronic fetus hypoxaemia originated by anaerobic metabolism and increased the fetal lactic acid production, respectively.
