Correlation between different Fetal Surveillance Tests and Pregnancy Outcome in Prolonged Pregnancy

Abstract

Prolonged pregnancy has traditionally been defined as pregnancy continued beyond completed 42 weeks or 294 days from the first day of the last normal period (LMP). Recently, it was proved that the risk of adverse perinatal outcome increases af'ler completed 41 weeks of gestation and it is wise to start the close monitoring of the pregnancy at this gestational age.

The incidence of postdate pregnancy vanes from 4% to 14% in different studies with an average of about I 0%. Prolonged pregnancy is a real problem in modern obstetrics. It carries many problems for pregnancy, labor and fetal outcome. It is associated with increased risk of perinatal morbidity and mortality.

Assessment of fetal well being is a corner stone. In the management of prolonged pregnancy. AntE'partum detection of ICtus at risk in utero remains a major challenge in modern obstetric practice.

The Biophysical pro(ile (131'P) appears to be an effective technique for assessing the fetal condition. In this study included combined observation and scoring system of live biophysical parameter. Non-stress test, qualitative amniotic fluid volume, fetal movements, breathing movements and fetal tone adding the result of BPP was taken contraction stress test (CST) for fetal well-being in response to stress denoted by uterine contractions. The CST has the advantage as a pnmary surveillance method detecting hypoxia of the fetus.
