Pregnancy Beyond 40 Weeks and Feto-Maternal Outcomes

Abstract

Background : pregnancy beyond 40 weeeks associated poor feto maternal and neonatal outcomes.several
evidences showed poor perinatal outcomes in pregnancy beyond 40 weeks.This study conducted to find out the
fetomaternal outcome of pregnancy beyond 40 weeks.
Methods : Study is prospective cross sectional study.Total 76 patients with uncomplicated prolonged pregnancy
filling inclusion and exclusion criteria and admitted in department of obstetrics and gynecology at a tertiary care
hospital.The Study aim was to know fetomaternal outcome in pregnancy beyond 40 weeks in regards of
spontaneous and induced labour.
Results : 46 (60.52%) patients were in the age group of 20-30 years,42 (55.26%) were between 41-42 weeks of
gestation according to their LMP. In 17 (22.36%) patients mode of delivery was caesarean section, in whom most
common indication being fetal distress in 41.17% followed by failure to progress in 23.52%. In present study
perinatal morbidity like Iufd,neonatal asphyxia, MAS, RDS were 5.26%, 9.21%, 7.89% and 5.26% respectively.
Maternal morbidity like prolonged labor, PPH, fever, wound infection were 11.84%, 9.21%, 5.26% and 5.26%
respectively.
Conclusions: If patient take regular antenatal check-up, incidence of postdate pregnancy can be decreased and
it is required because there is definite risk to fetus as pregnancy continuing beyond 40 weeks of gestation is
associated with increased perinatal morbidity and mortality especially those who do not come for regular antenatal
check-up.Exact term of pregnancy must be confirmed because it is very important as many patients don't have
regular menstrual history and LMP.Exact Last menstrual period date confirmed by first trimester ultrasound which
is most important non-invasive method and readily available.
