Frequency of third trimester umbilical artery Doppler for improving neonatal outcomes in high-risk pregnancies: a randomized trial.

ABSTRACT:

Objective

Umbilical artery Doppler ultrasonography is useful for high-risk prenatal surveillance. However, according to a systematic review and meta-analysis by the Cochrane pregnancy and childbirth group, the optimal frequency with which such surveillance should occur remains unclear. In the current study, we aimed to investigate whether performing umbilical artery Doppler on a weekly basis enables earlier detection of changes in utero-placental blood flow than the recommended bi-weekly (i.e., fortnightly) regimen and its impact on perinatal outcomes.

Methods

This randomized controlled study included 292 high-risk pregnant women in their third trimester who attended the Ain Shams University Maternity Hospital in Egypt from January 2018 to September 2019. The women were rand
