Predictors of meconium stained amniotic fluid : a possible strategy to reduce neonatal morbidity and mortality

Abstract

1 Pediatrics and of 2 RESULTS : MSAF was present in 159 (15.76%) of the 1009 deliveries studied. Thin and thick MSAF constituted 39% and 61% cases respectively. Univariate analysis identified eight risk factors (P 30, primigravidity, postdated pregnancy, prolonged labor, fetal distress, and cord problems. Logistic regression analysis identified four independent risk factors for MSAF - postdated pregnancy, fetal distress, cord problems, and fetal growth retardation (positive predictive value - 25.3%, negative predictive value - 89.7%), and three for thick MSAF - maternal age >30, postdated pregnancy, and fetal distress (positive predictive value - 19.5%, negative predictive value - 94.5%). CONCLUSION(S) : Mothers with postdated pregnancies, cord problems in labor, and fetal distress are at increased risk of developing MSAF. Thick MSAF is likely with maternal age >30, postdated pregnancy, and fetal distress. In the absence of these factors the risk of meconium in liquor is low.
