目的研究早产儿生后Apgar评分与血气分析的相关性,以指导早产儿临床对窒息的诊断及处理。方法用i-STAT型血气分析仪对新生儿350例生后1、5min脐动脉血进行血气测定,并与Apgar评分进行相关分析。结果血pH早产儿组为7.24±0.04,足月儿组为7.22±0.04;Apgar评分早产儿组1minApgar评分≤7的有75名,占总数的30%;5minApgar评分≤7的有50名,占总数的20%;1min或5minApgar评分≤7的有75名,占总数的30%;足月儿1min和5minApgar评分≤7的有9名,占总数的90%。两组比较有显著差异(P<0.01)。结论脐动脉血、pH、氧分压、二氧化碳分压与早产儿组低Apgar评分有关系。血气分析结果为诊断早产儿窒息的主要指标。
Objective To study the relationship between Apgar score and blood gas analysis in premature infants to guide the diagnosis and treatment of asphyxia in premature infants. Methods The i-STAT blood gas analyzer was used to measure the blood gas of 350 neonates with umbilical arterial blood 1 and 5 minutes after angiography, and correlated with Apgar score. Results Serum pH was 7.24 ± 0.04 in premature infants and 7.22 ± 0.04 in term infants. In preterm infants with preterm infants, 75 had 1 min of Apgar scores ≤7, accounting for 30% of the total; 50 had 5 min of Apgar scores ≤ 7, accounting for 75% of patients with a score of 7 or less in 1min or 5min, accounting for 30% of the total; 9% of children with full-term children in 1min and 5minApgar scores ≤7, accounting for 90% of the total. There was significant difference between the two groups (P <0.01). Conclusion Umbilical arterial blood, pH, partial pressure of oxygen, partial pressure of carbon dioxide have a relationship with low Apgar score in preterm infants. Blood gas analysis results for the diagnosis of asphyxia in preterm children the main indicators.
