Clinical assessment of an infant's heart rate (HR) in the delivery room (DR) has been reported to be inaccurate. We compared auscultation of the HR using a stethoscope with electrocardiography (ECG) and pulse oximetry (PO) for determining the HR in 92 low-risk newborn infants in the DR. Caregivers auscultated the HR while masked to the HR on the monitor. Auscultation underestimated ECG HR (mean difference (95% CI) by -9 (-15 to -2) beats per minute (bpm)) and PO HR (mean difference (95% CI) by -5 (-12 to 2) bpm). The median (IQR) time to HR by auscultation was 14 (10-18) s. As HR was determined quickly and with reasonable accuracy by auscultation in low-risk newborns, study in high-risk infants is warranted.
临床评估显示，在分娩室（DR）中对婴儿心率（HR）的听诊并不准确。我们比较了 92 例低危新生儿在 DR 中使用听诊器听诊 HR 与心电图（ECG）和脉搏血氧饱和度（PO）测定 HR 的情况。护理人员在不了解监护仪上 HR 的情况下进行听诊。听诊法低估了 ECG HR（平均差值（95%CI）为-9（-15 至-2）次/分钟（bpm））和 PO HR（平均差值（95%CI）为-5（-12 至 2）bpm）。听诊法确定 HR 的中位数（IQR）时间为 14（10-18）秒。由于在低危新生儿中，听诊法可以快速且具有合理的准确性确定 HR，因此有必要对高危婴儿进行研究。
