OBJECTIVE
There are limited evidence-based published heart rate ranges for premature neonates. We determined heart rate ranges in premature neonates based on gestational and post-menstrual age.
STUDY DESIGN
Retrospective observational study of premature neonates admitted to the neonatal intensive care unit at the University of Virginia between January 2009 and October 2015. We included gestational ages between 23 0/7 weeks and 34 6/7 weeks. We stratified data by gestational and post-menstrual age groups.
RESULTS
Over two billion heart rate values in 1703 neonates were included in our study. We established percentile-based reference ranges based on gestational and post-menstrual age. Our results demonstrate a slight increase in the initial weeks after birth, followed by a gradual decline with age. The baseline heart rate is lower with advancing gestational age.
CONCLUSIONS
Knowing heart rate reference ranges in the premature neonatal population can be helpful in the bedside assessment of the neonate.
目的
早产儿的心率范围有有限的循证依据。我们根据胎龄和月经后年龄确定早产儿的心率范围。
研究设计
这是一项回顾性观察性研究，纳入了 2009 年 1 月至 2015 年 10 月期间在弗吉尼亚大学新生儿重症监护病房就诊的早产儿。我们纳入的胎龄为 23 0/7 周至 34 6/7 周。我们根据胎龄和月经后年龄组对数据进行分层。
结果
我们的研究纳入了 1703 名新生儿的超过 20 亿次心率值。我们根据胎龄和月经后年龄建立了基于百分位数的参考范围。我们的结果表明，出生后最初几周心率略有增加，随后随着年龄的增长逐渐下降。随着胎龄的增加，基础心率会降低。
结论
了解早产儿的心率参考范围有助于对新生儿进行床边评估。
