Assesment of fetal acidosis in infants with meconium-stained amnıotic fluid

Amaç

To determine the fetal acid-base status in patients with meconium-stained amniotic fluid in labor and to evaluate the differences in umbilical artery pH values with regard to the consistency of meconium.

Yöntem

One hundred and six pregnant women in spontaneous labor at term with meconium-stained amniotic fluid were included in the study. The attending physician determined the grade of meconium by visual examination at the bedside. Immediate umbilical artery blood was obtained at each delivery. PH value <7.20 was defineci as neonatal acidosis.

Bulgular

The rate of neonates having pH values <7.20 was %23.6. Analysis of cord arterial pH for grades of meconium yielded a significant acidotic shift for the thick-meconium group (p=0.001) and also neonatal care unit admissions were significantly higher in the thick-meconium group (p<0.001). Sonuç

Thick meconium is a more ominous sign than is thin meconium and should alert the physician to a high risk fetal condition.
