Özet

Abstract Doppler ultrasound is widely used in obstetrics. However, the biological effects of high energy from Doppler ultrasonography have not been clearly revealed. Animal studies have shown negative effects on the fetus, but studies on humans are limited. The aim of this study is to evaluate the effect of Doppler ultrasonography used in early pregnancy weeks (6-12 week) to detect fetal cardiac activity on pregnancy outcomes (number of births and abortions, type of delivery, cesarean indications, birth week, preterm labor rates, birth weights, low-birth-weight infant). For fetal cardiac activity, 359 patients examined with Doppler ultrasound constituted the study group and 252 patients examined without Doppler ultrasound constituted the control group. The pregnancy outcomes were compared. According to the results of the study, no adverse effects of Doppler ultrasound were found. These results were thought to be related to the use of Doppler according to safety recommendations. Keywords Doppler ultrasonography, Fetal cardiac activity Obstetric-neonatal results
