Abstract
SUMMARY
T
he most common cause of fetal mortality in developed countries is preterm birth. More importantly, permanent disabilities are seen in infants surviving death. Although care before and after delivery has been effective in improving infant survival. Preterm birth still counts for 70% of infant mortality and 75% of infant disabilities. It is the major cause of disability for infants regardless of forms of congenital abnormalities.
The problem of preterm birth is one of the important reasons for admission to the hospital during pregnancy.
It also creates abundant economic problems for families and in spite of all efforts for prevention, it continues to be on the rise.
Bleeding during pregnancy, is among the most stressful cases for both patients and physicians. Spotting or bleeding during pregnancy is prevalent especially in the first trimester.
In general, bleeding during the first trimester is a predictor of adverse outcomes of pregnancy about half of the cases of first trimesteric vaginal bleeding is unknown therefore the possible mechanism of preterm labor following bleeding in early pregnancy is still unclear.
Thus this study aims to determine whether there is a relation between vaginal bleeding in the first trimester of pregnancy and preterm labor or not. In order to be able to perform more preventive measures for preterm labour.
The current study was a cohort study that started from november 2017 till june 2018. was conducted on240 singilton pregnant females divided into two groups (pregnant with vaginal bleeding n=120 and pregnant without vaginal bleeding n=120).and antenatal follow up for these cases to observe which developed preterm labour (outcome).
Data was collected through detailed history personal for any special habbits obstetrics for previous history of preterm to uplly stricetly exclusion criteria ,present pregnancy history for bleeding amount ,recurrence, association with pain ,relation to coitus and timming examination and ultrasonography for detection of positive fetal life and exclude major anomalies and multiple pregnancy.
Results: the patients with vaginal bleeding had a significant higher prevalence of preterm labour than patients without vaginal bleeding, .were incidence rate among exposed20/100=20% and among unexposed 8/100=8% . so relative risk is 2.5 which means that patients with vaginal bleeding from 8 to 13 weeks are more subjected 2 and half times more to pretem labour than patients without vaginal bleeding.
According to the results of the current study, Any patient with threatened abortion should be recommended to have more intense antenatal care through her pregnancy as she is at higher risk to develop preterm labour. And abolshing any other risk factor for preterm labour.
