[Perinatal outcome in patients with meconial amniotic fluid in labor]. / Resultado perinatal en pacientes con líquido amniótico meconial durante el trabajo de parto.

ABSTRACT

PURPOSE: To evaluate the perinatal morbidity and mortality with the presence of meconial amniotic fluid. MATERIAL AND METHODS: Retrospective study of case review, performed from 1st of June 1995 to May 1997. The patients included were at delivery, with a pregnancy of 32 weeks or older and had meconial amniotic fluid. The variables analyzed were motherhood age, pre-existing associated illness, resolution of the pregnancy, PSS interpretation, fetal weight, Apgar and final destiny of the product. RESULTS: Of the 432 patients the motherhood aged varied from 13 to 43 years old, mean 27.4; with a number of pregnancies from 1 to 10, mean 2.25. The gestational age went from 32.2 to 42.4 weeks. The fetal weight varied form 1025 to 5080 g. The Apgar grade mean was 7 at the first minute and 8 at the fifth. The pregnancy was interrupted by cesarean in 52.5%. Although there was not a significant difference with the arterial gas, the density of the amniotic fluid did determine the final destiny of the product. CONCLUSIONS: There is a relation between the presence of amniotic fluid and the Apgar grade; both determining the final destiny of the product. When the amniotic fluid had thick meconium the products had a greater morbidity.
