When the quality of the evidence for the main comparison of 'All Doppler versus no Doppler' was assessed with GRADE software, the outcomes of perinatal death and serious neonatal morbidity data were graded as of low quality. There was no evidence of group differences for the outcomes of caesarean section, neonatal intensive care admissions or preterm birth less than 37 weeks. However, these results are based on a single trial, and we would recommend caution when interpreting this finding.

Only one included trial assessed serious neonatal morbidity and found no evidence of group differences (RR 0.99, 95% CI 0.06 to 15.75 one study, 2016 participants).įor the comparison of a single Doppler assessment versus no Doppler, evidence for group differences in perinatal death was detected (RR 0.36, 95% CI 0.13 to 0.99 one study, 3891 participants). Results for perinatal death were as follows: (average risk ratio (RR) 0.80, 95% confidence interval (CI) 0.35 to 1.83 four studies, 11,183 participants). There were no group differences noted for the review's primary outcomes of perinatal death and neonatal morbidity. Overall, routine fetal and umbilical Doppler ultrasound examination in low-risk or unselected populations did not result in increased antenatal, obstetric and neonatal interventions. Overall and apart from lack of blinding, the risk of bias for the included trials was considered to be low. All trials had adequate allocation concealment, but none had adequate blinding of participants, staff or outcome assessors. We included five trials that recruited 14,624 women, with data analysed for 14,185 women. There were no improvements identified for either the baby or the mother, though more data would be needed to prove whether it is effective or not for improving outcomes. The studies were not of high quality and were all undertaken in the 1990s. The review of trials of routine Doppler ultrasound of the baby’s vessels in pregnancy identified five studies involving more than 14,000 women and babies.

However, its value as a screening tool in all pregnancies needs to be assessed as there is a possibility of unnecessary interventions and adverse effects. Using it in high-risk pregnancies, where there is concern about the baby's condition, shows benefits. It is used in pregnancy to study blood circulation in the baby, uterus and placenta. It is possible that medical interventions might improve outcomes for these babies, if they can be identified. Doppler ultrasound uses sound waves to detect the movement of blood in vessels. This test may be done as an alternative to more-invasive procedures, such as angiography, which involves injecting dye into the blood vessels so that they show up clearly on X-ray images.Ī Doppler ultrasound test may also help your doctor check for injuries to your arteries or to monitor certain treatments to your veins and arteries.One of the main aims of routine antenatal care is to identify babies who are not thriving in the womb.

During a Doppler ultrasound, a technician trained in ultrasound imaging (sonographer) presses a small hand-held device (transducer), about the size of a bar of soap, against your skin over the area of your body being examined, moving from one area to another as necessary.
