Rapid and accurate heart rate assessment is essential in neonatal resuscitation, particularly for very premature infants where delays can impact timely intervention. A wireless heart rate monitor (NeoBeat) device has been validated in term babies but not in smaller preterm infants. We sought to validate the use of the Neobeat device compared to standard EKG in extremely preterm neonates during resuscitation.
A prospective observational study of very premature neonates undergoing routine resuscitation was conducted at a tertiary care center. Heart rate data were simultaneously recorded using the NeoBeat wireless monitor and a standard three-lead EKG.
Thirty very preterm infants (gestational age, (GA) 26.6 ± 1.9 weeks and birth weight range (250-1310 g)) were enrolled. A total of 1690 heart rate pairs were analyzed. A strong correlation and tracking observed between NeoBeat and EKG-derived heart rates (Pearson r = 0.96, Spearman ρ = 0.95), with a mean absolute difference of 3.76 beats per minute (bpm). Correlation remained robust across different resuscitation interventions (Intubation: r = 0.93 vs. No Intubation: r = 0.90, p = 0.207, PPV: r = 0.93 vs. No PPV: r = 0.87, p = 0.726).
In very preterm infants, NeoBeat wireless monitor achieved 96 % precision (r = 0.96) and maintained a mean absolute difference of 3.76 bpm compared to EKG, supporting its reliability and accuracy for real time neonatal monitoring, including infants weighing as little as 250 g, though statistical power in this range was limited. Randomized studies comparing NeoBeat to standard EKG are warranted to confirm these findings in extremely preterm infants and explore whether NeoBeat improves clinical outcomes.
在新生儿复苏中，快速准确地评估心率至关重要，尤其是对于极早产儿，因为延迟可能会影响及时干预。一种无线心率监测仪（NeoBeat）已在足月儿中得到验证，但在更小的早产儿中尚未得到验证。我们试图在复苏期间将NeoBeat设备与标准心电图（EKG）进行比较，以验证其在极早产儿中的使用。
在一家三级护理中心对接受常规复苏的极早产儿进行了一项前瞻性观察研究。使用NeoBeat无线监测仪和标准三导联EKG同时记录心率数据。
纳入了30名极早产儿（胎龄（GA）26.6±1.9周，出生体重范围为250 - 1310克）。共分析了1690对心率数据。观察到NeoBeat与EKG得出的心率之间具有很强的相关性和跟踪性（Pearson相关系数r = 0.96，Spearman秩相关系数ρ = 0.95），平均绝对差值为每分钟3.76次心跳（bpm）。在不同的复苏干预措施中相关性仍然很强（插管：r = 0.93 对比未插管：r = 0.90，p = 0.207；正压通气：r = 0.93 对比未进行正压通气：r = 0.87，p = 0.726）。
在极早产儿中，NeoBeat无线监测仪的精度达到96%（r = 0.96），与EKG相比平均绝对差值为3.76 bpm，这支持了其在实时新生儿监测中的可靠性和准确性，包括体重低至250克的婴儿，尽管该范围内的统计效力有限。有必要进行将NeoBeat与标准EKG进行比较的随机研究，以在极早产儿中证实这些发现，并探索NeoBeat是否能改善临床结局。
