DOPPLER ULTRASOUND PREGNANCY TRIAL

Study authors were contacted for additional information.Įleven studies involving nearly 7000 women were included.

DOPPLER ULTRASOUND PREGNANCY TRIAL

Trial quality was assessed and data were extracted by both reviewers. Randomised trials of Doppler ultrasound for the investigation of umbilical artery waveforms in high risk pregnancies compared to no Doppler ultrasound. We searched the Cochrane Pregnancy and Childbirth Group trials register. The objective of this review was to assess the effects of Doppler ultrasound in high risk pregnancies on obstetric care and fetal outcomes. It is also possible that Doppler ultrasound could encourage inappropriate early delivery. 2016 28(7).Abnormal waveforms from Doppler ultrasound may indicate poor fetal prognosis. Diagnosis of abnormal pregnancy and outcomes by color Doppler ultrasound. Pregnancy: Prenatal Ultrasonography: Test Details Role of colour Doppler indices in the diagnosis of intrauterine growth retardation in high-risk pregnancies. Role of color doppler in pregnancy induced hypertension (a study of 100 cases). Gray scale and color Doppler sonography in the third stage of labor for early detection of failed placental separation.

If ignored, it can lead to complications such as excessive blood loss in the mother. It is also performed to diagnose placenta accreta, a condition, in which, the placenta is deeply attached to the inside of the woman's womb, so that a part of the placenta stays attached to the womb even after delivery. Ultrasound pregnancy-colour Doppler can be used to guide the removal of tissue remnants in the womb following delivery.

Duodenal stenosis, ie, a partially blocked duodenum (first part of the small intestine) in the baby.

Diaphragmatic hernia, ie, an abnormal opening in the muscle called the diaphragm, which is present between the chest and abdomen and helps in breathing.

Pulmonary hypoplasia, ie, incomplete development of lungs.

Malformations in blood vessels of brain.

Some of the following conditions in a baby can be diagnosed using ultrasound pregnancy-colour Doppler: It is also performed between 31 to 41 weeks of pregnancy to diagnose intrauterine growth retardation of the baby. It can determine the flow of fluid in foetal trachea and blood flow through its blood vessels, ie arteries and veins, which can then be used to detect conditions of the respiratory system and blood circulation in the foetus.

This test can be performed between 10 to 12 weeks of pregnancy to diagnose abnormalities such as malformations in the foetus. How much does a Colour Doppler Ultrasound cost?.What do Colour Doppler Ultrasound results mean?.How is Colour Doppler Ultrasound performed during pregnancy?.

How do you prepare for a Colour Doppler Ultrasound?.Why is Colour Doppler Ultrasound performed during pregnancy?.Ultrasound colour Doppler also assists in identifying the motion of foetal solid tissues, such as heart walls.Ĭolour Doppler is advantageous over a standard ultrasound procedure because the conventional ultrasound does not show blood flow details in blood vessels of the foetus. These colours help to identify the speed and direction of blood flow through arteries, veins and organs such as heart of the foetus. It is a combination of ultrasound pulse-echo and ultrasound Doppler techniques, which utilises a computer to change the sound waves used in Doppler imaging into different colour to generate a coloured image. Ultrasound pregnancy-colour Doppler is a type of Doppler imaging technique that identifies the direction of movement of blood and its speed in blood vessels.
