Evaluation of Fetal Breathing-Related Nasal Fluid Flow Doppler in the Third Trimester in Pregnant Women with Fetal Growth Restriction: Preliminary Observations

Abstract Objective To investigate the fetal breathing-related nasal fluid flow Doppler waveforms as an indicator of fetal respiratory function in fetuses diagnosed with fetal growth restriction (FGR) in the third trimester. Materials and Methods This prospective, non-interventional case-control study was conducted on 96 pregnant women, including 23 pregnant women diagnosed with FGR in the third trimester as the FGR group and 73 healthy pregnant women with fetuses appropriate for gestational age (AGA) as the control group. Fetal breathing-related nasal fluid flow Doppler was examined in the fetuses of the partici…
