Doppler velocimetry of fetal pericardial fluid

International Journal of Gynecology & Obstetrics, 2009
AbstractObjectiveTo investigate the flow of normal fetal pericardial fluid (PF) with increasing gestational age using Doppler velocimetry.MethodNinety‐five fetuses between 18 and 37 weeks of gestation with PF within the normal range were studied. PF was measured in 4‐chamber view using M‐mode or real‐time ultrasound.

Technical Aspects of Fetal Doppler Measurements

Gynecologic and Obstetric Investigation, 2010
Doppler ultrasound may be a valuable tool in the estimation of fetal well-being. Nevertheless, a good understanding of the basic principles of ultrasound and the applied circuitry is necessary to obtain useful information. Some physical principles and limitations of ultrasound are discussed and the basics of the electronic devices are mentioned ...

CIRCULATORY DOPPLER PARAMETERS IN FETAL HYPOXAEMIA

Prenatal Diagnosis, 1996
A 32-year-old pregnant woman (gravida 1, para 0) was delivered at 27 weeks of gestation by elective Caesarean section because of regular fetal heart rate (FHR) decelerations. Doppler ultrasound assessment of the middle cerebral artery (MCA) and the ductus venosus (DV) showed pathological results, whereas the umbilical artery waveforms were normal ...

Fetal Doppler: How to Keep it Safe?

Clinical Obstetrics & Gynecology, 2010
Ultrasound's record of safety seems to be perfect, with no undisputed reports of adverse effects in humans. However, all epidemiologic studies published so far are based on information obtained with pre-1992 machines, when allowed maximal in-situ intensity for fetal use was increased. Many fetuses are examined very early in pregnancy, a time of greater

Fetal arterial Doppler-IUGR and hypoxia

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1997
Vascular resistances of various fetal areas are assessed by Doppler ultrasound. The PI, RI and S/D indices are measured on the cerebral, renal, aortic and umbilical Doppler spectrum. Ratios of these indices based on the comparison of the cerebral (Rc) and the umbilical (Rp) resistances, or carotid (Rcc) and umbilical resistances, or cerebral (Rc) and ...

Fetal Doppler: the panacea for fetal heart monitoring

British Journal of Midwifery, 2000
One of the midwife's responsibilities during the antenatal period is to detect the fetal heart rate. This is one of the most important indicators as to the wellbeing of the developng fetus. The activities of a midwife defined by The European Union Midwives Directive states that each midwife should:

Doppler ultrasonography of the human fetal pulmonary circulation

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2001
textabstractPulmonary hypoplasia is a condition characterized by a decrease in the number of lung cells, airways and alveoli with a resulting decrease in organ size and weight. The reported incidence of pulmonary hypoplasia in the general population is about 1 per 1000 live births and it is one of the most common single abnormalities found at ...
