BACKGROUND
The aim of this study was to describe the effect of factors on time to reach a pulse oxygen saturation (SpO2) level of 90% in preterm infants in the delivery room.
METHODS
Preterm (<35 gestational age) infants who did not require supplemental oxygen were included in the study. Continuous recordings were taken by pulse oximetry during the first 15 min of life.
RESULTS
Of 151 preterm infants, 79 (52.3%) were female and 126 (83.5%) were delivered by cesarean section. Target saturation level (≥90%) was achieved faster in preductal measurements. Mean times taken to have a preductal and postductal SpO2 level of 90% were significantly lower in preterm babies born by vaginal delivery, with umbilical arterial pH ≥ 7.20 and whose mothers were non-smokers during pregnancy.
CONCLUSIONS
Differences in achievement of target saturation level were influenced by multiple factors (birth way, probe location, maternal smoking and umbilical blood gas pH) in the delivery room during resuscitation of preterm babies.
背景
本研究旨在描述分娩室中影响早产儿达到脉搏血氧饱和度（SpO2）90%所需时间的因素。
方法
纳入不需要补充氧气的早产儿（胎龄<35周）。在出生后前15分钟通过脉搏血氧饱和度仪进行连续记录。
结果
151例早产儿中，79例（52.3%）为女性，126例（83.5%）通过剖宫产分娩。在导管前测量中更快达到目标饱和度水平（≥90%）。经阴道分娩、脐动脉pH≥7.20且母亲孕期不吸烟的早产儿，导管前和导管后SpO2达到90%的平均时间显著更短。
结论
在早产儿复苏过程中，分娩室中目标饱和度水平的达成差异受多种因素（分娩方式、探头位置、母亲吸烟情况和脐血气pH）影响。
