Relationship of the Findings of Colour Doppler and Non-Stress Test with the Perinatal Outcome among the Cases of Intra-Uterine Growth Restriction

Introduction: Intrauterine growth restriction is the second most common cause of perinatal mortality and morbidity after prematurity. Etiologies can be maternal, fetal or placental. The correct detection of compromised IUGR fetus to allow timely intervention is a main objective of antenatal care. Many of IUGR patients presents in their third trimester for the first time for antenatal examination. Such patients warrant a highly sensitive and specific diagnostic test which can be noninvasively applied on a large scale. Apart from various other non-invasive tests like USG, NST, Doppler flow studies give us vital information regarding the fetus in utero. Hence the present study is aimed at exploring the association of colour Doppler and non-stress test findings with the perinatal outcome in the fetuses with IUGR. Aim: To study relationship of Doppler and NST with perinatal outcome in IUGR cases. Material and Methods: A Prospective observational study was conducted on 70 patients of IUGR from August 2013 to November 2015 in Department of Obstetrics and Gynaecology , Dr. Vasantrao Pawar Medical College, Hospital & Research Center. Inclusion criteria: Patients with diagnosed singleton pregnancies with IUGR at gestational age more than 32weeks not in labour. Exclusion criteria: Patients with congenital anomalous fetus, diabetes or acute placental insult. Patients were followed up with serial Umbilical artery Doppler and NST. Perinatal outcome was correlated with the last Doppler and NST within 7days prior to delivery. Results: Perinatal outcome is worst in patients with both NST and Doppler are abnormal and best among patients with both normal NST and Doppler. Conclusion: Doppler predicts fetal compromise earlier as compared to NST.
