Doppler changes as the earliest parameter in fetal surveillance to detect fetal compromise in intrauterine growth-restricted fetuses.

INTRODUCTION

It is estimated that 3-10% of infants are growth restricted. Growth disturbances may have long-term issues. Doppler allows insight into the fetal response to intrauterine stress.

OBJECTIVE

The aim of this study was to detect fetal compromise in intrauterine growth-restricted (IUGR) fetuses by means of biophysical profile (BPP) vis-à-vis Doppler velocimetry studies of the fetal umbilical artery, and to find out which of the two is a better and earlier predictor of fetal compromise.

METHODS

A prospective study was conducted on a total of 50 singleton pregnancies with IUGR between 28 and 42 weeks of gestation. Study patients were managed expectantly with nonstress testing and amniotic fluid assessment, BPP and Doppler velocimetry studies of the fetal umbilical artery.

RESULTS

Fetal outcome was poor in 5/50 (10%) of the fetuses, defined as presence of all of the following: poor Apgar test score, neonatal intensive care unit stay, necrotizing enterocolitis, and low birth weight. Of the four with abnormal BPP, 50% had poor fetal outcomes. Out of 46 with normal BPP, 6.5% had poor fetal outcomes.

CONCLUSION

Inference drawn from the study is that the Doppler technology provides us the opportunity for repetitive noninvasive hemodynamic monitoring in IUGR pregnancies.
