Summary

The aim of the current study was to produce a high quality evidence on the best frequency of performing umbilical artery Doppler for high risk pregnant women in the third trimester.

Detailed description

Nowadays, high risk pregnancy forms a significant increasing proportion of any pregnant population, according to some authors up to 50% of all pregnancies would have the label of high risk pregnancies. At present, it is recommended that high risk pregnancies, thought to be at risk of placental insufficiency should be monitored with Doppler studies of the umbilical artery. Doppler assessment of the placental circulation plays an important role in screening for impaired placentation and its complications of intrauterine growth restriction. The purpose of umbilical artery Doppler surveillance is to predict fetal academia thereby allowing timely delivery prior to irreversible end-organ damage and intrauterine fetal death. According to a Cochrane Pregnancy and Childbirth Group's systematic review and meta-analysis, in which Published and unpublished randomised and quasi-randomised trials evaluating the effects of one or more described antenatal fetal surveillance regimens were searched, the optimal frequency of umbilical artery Doppler surveillance is unclear. Our randomized controlled study was conducted on patients with high risk pregnancies at their third trimester who attended Ain Shams University Maternity Hospital. A total of 292 high risk pregnant women fulfilling the inclusion criteria were selected by random sampling and divided between two groups with 146 patients in each group. Group I underwent Doppler every other week and Group II underwent Doppler once weekly.

Conditions

DIAGNOSTIC_TEST	Umbilical artery Doppler	Umbilical artery Doppler ultrasound will be performed by most expert sonographer in umbilical artery Doppler at the special care unit, using a 3.5MHz transabdominal probe of SAMSUNG MEDISON, SONOACE R5 ultrasound machine, using the standard protocol of the unit for minimizing the interobserver variations.
