Abstract

Objectives: Newborns with fetal growth restriction (FGR) are at a high risk of prenatal mortality and morbidity compared to infants with appropriate intrauterine growth. The importance of Doppler ultrasound as a non-invasive method for estimating the pulmonary artery pressure (PAP) in newborns and adults has been mentioned in many studies. This study investigated the relationship between peak systolic velocity in pulmonary artery color Doppler and neonatal respiratory outcomes in FGR with abnormal fetoplacental circulation. Materials and Methods: In this prospective cohort study, 60 pregnant women with a gestational age of 32-37 weeks were studied in two groups: group I (women with fetus suspected of FGR according to ultrasound assessment) and group II (women with normal pregnancy). All women underwent Doppler ultrasound of pulmonary artery, umbilical artery, middle cerebral artery, and venous ductus. The pick systolic velocity (PSV) of the trunk of the pulmonary artery was evaluated in the fetus of all participants. After delivery, all infants were studied for respiratory outcomes at birth. Finally, variables included gestational age, fetal estimated weight based on Hadlock table, fetal amniotic fluid index, maternal parity, umbilical artery pulsatility index (PI), middle cerebral artery PI, maximum pulmonary artery velocity (PV), umbilical artery to middle cerebral artery index ratio, and the number of infants admitted to the newborn intensive care unit (NICU) due to respiratory distress were compared between two groups. Results: Our results showed a significant association between pulmonary artery PI in FGR fetuses with abnormal fetoplacental circulation. The rate of early NICU hospitalization of infants in the group I was higher than group II due to respiratory diseases, as well as the need for oxygen and continuous positive airway pressure (CPAP). Conclusions: Pulmonary artery color Doppler ultrasound can be effective in diagnosing FGR embryos during pregnancy and making the necessary predictions to reduce prenatal mortality and morbidity in these infants.
胎儿生长受限伴胎胎盘循环异常时肺动脉收缩峰值速度与新生儿呼吸结局的关系:一项前瞻性队列研究
目的:与正常宫内生长的婴儿相比,胎儿生长受限(FGR)新生儿的产前死亡率和发病率较高。许多研究都提到了多普勒超声作为一种无创方法评估新生儿和成人肺动脉压(PAP)的重要性。本研究探讨伴有胎胎盘循环异常的FGR患者肺动脉彩色多普勒峰值收缩速度与新生儿呼吸结局的关系。材料与方法:本前瞻性队列研究将60例胎龄为32 ~ 37周的孕妇分为两组:ⅰ组(经超声检查胎儿疑似FGR)和ⅱ组(正常妊娠)。所有女性均行多普勒超声检查肺动脉、脐动脉、大脑中动脉和静脉导管。在所有参与者的胎儿中评估肺动脉干的收缩速度(PSV)。分娩后,研究所有婴儿出生时的呼吸状况。最后,比较两组的胎龄、基于Hadlock表的胎儿估计体重、胎儿羊水指数、胎次、脐动脉脉搏指数(PI)、大脑中动脉PI、最大肺动脉流速(PV)、脐动脉与大脑中动脉指数之比以及新生儿因呼吸窘迫而入住新生儿重症监护病房(NICU)的婴儿数量。结果:我们的研究结果显示FGR胎儿肺动脉PI与胎儿胎盘循环异常有显著的相关性。由于呼吸系统疾病,以及需要吸氧和持续气道正压通气(CPAP), I组婴儿早期NICU住院率高于II组。结论:肺动脉彩色多普勒超声可有效诊断妊娠期FGR胚胎,并作出必要的预测,以降低这些婴儿的产前死亡率和发病率。
