In majority of the cases, it was PROM followed by PostDatism
as the main indication.
 In this study, 24% patients reported postdatism
as indication of induction of labor, which was 35% and 57.9% in the studies by Blanchette et al.
Utilization of US for dating has pushed the mean gestational age at delivery back a few days, tightened the distribution around the mean, and lowered the prevalence of postdatism
The rate of labor induction in term pregnancies increased from 12.7% in 1980 to 27% in 1995, largely because physicians are using different definitions for postdatism
, said Dr.
In infants admitted to NICU one of the risk factor attributed is postdatism
The most common indication being postdatism
20.5% of the patients underwent induction of labour using prostaglandin E2 gel, of these 5% of the patients were induced for postdatism
, 11.55% of the patients were induced because of preeclampsia; 2% were induced for imminent eclampsia and 2% were induced for oligohydramnios.
Labour was accelerated with syntocinon if necessary, induced labour for postdatism
. The primigravida who fulfilled the above said criteria were classified into three groups.
Since all women in the studies were induced for high risk factors like postdatism
, oligohydramnios, PROM, etc.
Out of 70 women studied, preterm labour is seen in 38.5% of patients; postdatism
8.7% cases of Pre-eclampsia out of which 7.6% were Placenta Grade-II and 9.6% cases were Placenta Grade-III, 1.3% cases polyhydramnios out of which 3% cases were Placenta Grade-II and no case of Placenta Grade-III, 2% cases of Postdatism
out of which 1.5% cases were Placenta Grade-II, 2.4% cases had Placenta Grade-III.
This may be due to increased duration of labour in primigravidas as compared to multigravidas, incidence of preeclampsia and postdatism
are also more common in primigravida in primigravida as compared to multigravidas.
