背景本研究的目的是确定最佳使用的信息从多普勒研究脐动脉，胸主动脉和大脑中动脉的管理与生长受限的妊娠。研究组由100名胎儿宫内生长受限的孕妇组成。多普勒血流速度波形从脐动脉，大脑中动脉和胸主动脉。根据脐动脉多普勒结果对妊娠进行分组。脐动脉搏动指数（PI）正常者29例，高PI者30例，舒张末期血流速度（AEDV）缺失者41例。随着脐动脉舒张期血流的恶化，新生儿出生体重和脐静脉pH值显著降低，围产儿死亡率显著增加（p
Back-ground. The aim of the study was to determine the best use of information obtained from Doppler studies of umbilical artery, thoracic aorta and middle cerebral artery in the management of pregnancies with growth restriction.Methods. The study group consisted of 100 pregnant women with intrauterine growth restricted fetuses. Doppler flow velocity waveforms were obtained from the umbilical artery, middle cerebral artery and thoracic aorta. The pregnancies were grouped according to the umbilical artery Doppler results. There were 29, 30 and 41 fetuses with normal and high PI (pulsatility index), and absent end-diastolic velocity (AEDV) in the umbilical artery, respectively.Results. Birth weight and umbilical vein pH at birth significantly decreased and perinatal mortality rates significantly increased with the worsening of the diastolic flow in the umbilical artery (p
