Apgar score (AS) is routinely used for assessment of newborns immediately after birth. Within acceptable limits, low saturations at birth are normal in vigorous newborn babies. Various studies have questioned the reliability of AS.
To detect whether AS is an accurate indicator of hypoxemia and to study the correlation of different components of AS with the arterial oxygenation saturation (SpO2) levels of normal newborns in the delivery room.
A prospective cross-sectional observational study on normal healthy neonates delivered vaginally in a tertiary level referral medical college.
SpO2 levels were monitored continuously in the newborns with a pulse oximeter and serial recording of SpO2 levels was done at 5 min intervals starting at 1 min of life until 30 min after birth. Simultaneously, AS was recorded in these newborns at 1 and 5 min of life.
Data was analyzed using the Mann-Whitney-U test.
AS at 1 and 5 min of life didn't correlate with the changes in SpO2 of newborns. In AS; though respiratory efforts and muscle tone were significantly correlated with SpO2 of the newborns, body color did not have significant correlation with simultaneously recorded SpO2.
A revised AS in which evaluation of color is replaced by pulse oximetry monitoring would prove to be a better tool for neonatal evaluation in the immediate postnatal period.
阿氏评分（AS）通常用于出生后立即对新生儿进行评估。在可接受范围内，活力充沛的新生儿出生时低血氧饱和度是正常的。各种研究对阿氏评分的可靠性提出了质疑。
检测阿氏评分是否是低氧血症的准确指标，并研究阿氏评分不同组成部分与产房正常新生儿动脉血氧饱和度（SpO2）水平的相关性。
在一所三级转诊医学院对经阴道分娩的正常健康新生儿进行前瞻性横断面观察研究。
用脉搏血氧仪持续监测新生儿的SpO2水平，从出生后1分钟开始，每隔5分钟连续记录SpO2水平，直至出生后30分钟。同时，在这些新生儿出生后1分钟和5分钟记录阿氏评分。
采用曼-惠特尼-U检验分析数据。
出生后1分钟和5分钟时的阿氏评分与新生儿SpO2的变化无关。在阿氏评分中，虽然呼吸努力和肌张力与新生儿的SpO2显著相关，但身体颜色与同时记录的SpO2没有显著相关性。
用脉搏血氧仪监测取代颜色评估的修订版阿氏评分，将被证明是出生后立即进行新生儿评估的更好工具。
