[The use of Doppler-ultrasound in obstetrics]
1Gynaekologisk obstetrisk afdeling Y, Arhus Kommunehospital.
Several investigations have suggested an association between intrauterine growth retardation or an adverse neonatal outcome and increased vascular resistance in the fetal and maternal uteroplacental circulation assessed by Doppler-ultrasound. Meta-analysis of nine randomized controlled trials showed that the use of Doppler-ultrasound in the surveillance of high-risk pregnancies reduced the perinatal mortality considerably. Taken together, there is evidence to suggest that Doppler-ultrasound is a valuable tool for discriminating between normal small and "sick" small fetuses. Screening in unselected populations of low-risk pregnancies, however, seems to be without any benefit.
