Abstract:
The Objective of this prospective obstructional study was to ascertain the relationship
between placental site? placental thickness. and maximum amniotic fluid pool diameter with
adverse intrapartum events such as fetal distress, lack of progress and postpartum
hemorrhage.The study was carried out in 520 pregnant women, who were divided in to three
groups as fellows: First group of 200 women, who had anterior placenta and the smgle
deepest vertical amniotic fluid diameter was more than 2crn were selected to study the effect
of placental thickness on intrapartum complications and postpartum haemarrhage. The
second group consisted of 200 women who had an anterior placenta was recruited for
studying the effect of single deepest vertical amniotic pool diameter on intrapartum
complications and the postpartum haemarrhage. The third group consists of 120 women
further divided in to four sub-groups, each of which each included 30 women. All had a
single deepest vertical amniotic fluid diameter more than 2cm with upper segment placenta.
Further they grouped into four according to the site of placental implantation (anterior,
posterior, fundal, lateral either right or left). Adverse intrapartum events such as fetal
distress, failure to 'Progress and postpartum haemarrhage were studied. There was an
increased risk of developing fetal distress during labour in those who had an anterior
placenta and deepest vertical amniotic fluid pool diameter less than 2cm compared to those
who had a deepest vertical amniotic fluid pool diameter more than 2cm.
