Maternal Neonatal Outcome in Relation to Placental Location, Dimensions in Early Pregnancy

Background: Placenta, which is the vital link between mother and fetus, is critical for maternal neonatal well�being. Its study in early pregnancy may provide information about maternal neonatal disorders. Aim: The study aimed to evaluate the relationship of placental location and dimensions in early pregnancy with maternal neonatal outcomes. Subjects and Methods: Primigravida (801) with singleton pregnancy at 10�weeks gestation and no past/present medical and obstetric disorder had ultrasonography for placental location and dimensions and were followed by ultrasonographic (USG) examination (at 20th week and 30th week), clinically for maternal�neonatal outcome. Statistical analysis was done by Epi 6 software (version 6.0, developed by Centres for Disease Control and Prevention, Atlanta, Georgia, USA) using Chi�square test and Fischer exact test for determining the statistical significance of the observations. P values of < 0.05 were considered as significant. Results: The number of primigravida with hypertensive disorders were 2.5% (5/200) with anterior, 20.5% (66/322) with fundal, and with posterior placenta 9.8% (12/123); Placental abruption 2.5% (5/200) with anterior, 6.8% (22/322) with fundal, and 3.3% (4/123) with posterior. With placental surface area <41 cm2 19.0% (37/195), with area 41-55 cm2 7.2% (30/416), and with area >55 cm2 6.8% (13/190), had hypertensive disorders. area < 41 cm2 11.3% (22/195), area 41-55 cm2 5.0% (21/416), and area >55 cm2 3.7% (7/190) had placental abruption. With thick placenta, 39.2% (58/148), thin, 9.4% (9/96), and normal placenta, 5.2% (29/562) had hypertensive disorders. With thick, 11.5% (17/148), thin 16.7% (16/96), and normal placenta 2.7% (15/562) had placental abruption. With anterior 0.5% (1/200), posterior 14.6% (18/123), fundal placenta 10.55% had preterm births. With anterior 7.5% (15/200), posterior 23.6% (29/123), fundal placenta 18% (58/322) had CS.With placental surface area <41 cm2 28.7% (56/195), area 41-55 cm2 14.2% (58/406), with > 55 cm2 14% (28/200) had CS. With thin 27% (25/91), with thick 36.1% (53/148), with normal placenta none had CS for fetal distress. Conclusions: Study of placental location and dimensions in early pregnancy is useful in identifying risks.
