The Effect of Antenatal Corticosteroid on Umbilical Artery Doppler Velocimetry in IUGR

Completed

• Conditions: Intrauterine Growth Restriction

• Registration Number: NCT05588986
• Lead Sponsor: Merve Demir

Brief Summary

The purpose of this study is to evaluate the effect of antenatal corticosteroid administration on umbilical artery Doppler velocimetry measurements in pregnancies complicated by IUGR.

Detailed Description

This study was conducted with pregnant women who were likely to have preterm birth and were treated with antenatal corticosteroids. Betamethasone was used as an antenatal corticosteroid. UA Doppler measurements (PI, S/D ratio, RI) before antenatal corticosteroid administration and 24 and 48 hours after the last dose of corticosteroid administration were evaluated in pregnant groups complicated with IUGR and uncomplicated with IUGR and compared with each other.

Primary Outcome Measures

Name	Time	Method
pulsatility index (PI)	2018-2019	Pulsatility Index (PI) = (Peak systolic velocity - end diastolic velocity)/(time averaged maximum velocity)
systolic:diastolic ratio (S/D ratio)	2018-2019	Peak systolic velocity/end diastolic velocity
Resistive Index (RI)	2018-2019	Resistive Index (RI) = (Peak systolic velocity - end diastolic velocity)/(peak systolic velocity)
