新生儿血流动力学无创监测在新生儿护理中的应用越来越多。方法包括通过心电图（EC）估计的无创心输出量和使用脉搏血氧仪作为灌注指数（PI）的外周灌注。我们的目的是评估在出生后的前2天内连续监测早产儿EC和PI的可行性，以及平均EC数据在信号质量（SigQ）分析中的作用。设计前瞻性观察研究。设置三级新生儿学术医院。患者早产儿从出生到48小时的妊娠< 32周。主要结果测量连续EC和PI测量。可行性被量化为具有高SigQ的时间，在EC中使用SigQ指数和在PI中使用异常代码进行分类。我们预定义的阈值为良好的可行性是最小的24小时，高SigQ为both. Results 22早产儿（中位数[IQR]胎龄28+ 6（26+ 0，30+ 4）周+天，出生体重960 [773，1,500] g）。我们记录了14名婴儿EC（非平均数据）和22名婴儿PI测量的最低24小时高SigQ。对于EC和PI，高SigQ记录时间的中位数（范围）%分别为74%（50%，88%）和94%（82%，96%）。使用1分钟平均EC数据导致增加的婴儿最低24小时的高SigQ到21 infants.ConclusionsEC和PI监测是可行的早产儿在第一个48小时内，但SigQ仍然是EC的问题。信号丢失被平均EC值掩盖。
ObjectiveThe use of noninvasive monitoring of neonatal hemodynamics is increasing in neonatal care. Methods include noninvasive cardiac output estimated by electrical cardiometry (EC) and peripheral perfusion as perfusion index (PI) using pulse oximetry. Our aim was to evaluate the feasibility to continuously monitor preterm infants with EC and PI during the first 2 postnatal days and the effects of averaging EC data in signal quality (SigQ) analysis.DesignProspective observational study.SettingTertiary neonatal academic hospital.PatientsPreterm infants< 32 weeks gestation from birth until 48 h.Main Outcome MeasuresContinuous EC and PI measurements. Feasibility was quantified as the time with high SigQ, classified using SigQ index in EC and exception codes in PI. Our predefined threshold for good feasibility was minimum of 24 h with high SigQ for both.ResultsTwenty-two preterm infants (median [IQR] gestational age 28+ 6 (26+ 0, 30+ 4) weeks+ days, birth weight 960 [773, 1,500] g) were included. We recorded a minimum of 24 h with high SigQ in 14 infants for EC (unaveraged data) and 22 infants for PI measurements. The median (range)% of recording time with high SigQ was 74%(50%, 88%) for EC and 94%(82%, 96%) for PI. Using 1 minute averaging for EC data resulted in an increase of infants with minimum 24 h of high SigQ to 21 infants.ConclusionsEC and PI monitoring are feasible in preterm infants within the first 48 h, but SigQ remains problematic for EC. Signal dropout is masked in averaged EC values.
