Determinación de variables metabólicas en recién nacidos con presencia de meconio en el líquido amniótico

some biochemical variables that have increased in hypoxic patients were studied in a group of newborn infants with meconial amniotic fluid and with no other sign of fetal suffering. the samples were obtained at the gynecoobstetric ward of "julio trigo" hospital. there were 14 cases in the group with meconial fluid and 51 in the control group. the studied variables: total and fetal haemoglobin, total proteins, glucose, lactate, aspartase aminotransferase and lactic dehydroginase, were determined in blood from the umbilical cord. the serum lactate concentration and the alanine aminotransferase and lactate dehydrogenase activity in the group with meconium was significantly higher than in the control group, which supports the criterium that the presence of meconium in the amniotic fluid is a sign of fetal suffering.
