Risk Factors Related to Intrauterine Fetal Death

Intrauterine fetal death is a traumatic event. Stillbirth rate is an important indicator to assess the quality of antenatal care. The objective of the study was to identify the risk factors related to intrauterine fetal death in patients admitted with intrauterine fetal death.

It was a descriptive study conducted in the department of Obstetrics and Gynaecology at B. P. Koirala Institute of Health Sciences from January to December 2014. Patients admitted with singleton pregnancy with intrauterine fetal death after 28 weeks gestation were included.

There were 11,006 obstetric admissions. Of them, 152 women had intrauterine fetal death. There were 128(84.2%) women between 20-35 years of age. Out of 152, 81(53.3%) women were preterm and 39(2.1%) women were postterm. Primigravida were 77(50.7%) followed by 35(23%) of second gravida. Hypertension was the commonest identified risk factor in 30(26.78%) women. Out of 152 women, 49(32.2%) had not received formal education. Ten (6.6%) women had a past history of fetal death. Four (2.6%) women had medical disorder before pregnancy. One hundred and twenty five (82.2%) women had vaginal delivery, 21(13.8%) had caesarean section and 6(3.9%) had laparotomy for rupture uterus. The commonest indication for caesarean section was placenta previa for 7(33.33%) women. Four (2.6%) women had diabetes. Ninety five (62.5%) were male and 57(37.5%) were female babies. Five (3.3%) babies had malformations.

Hypertension in pregnancy was found to be the most common identified risk factor for intrauterine fetal death.
