目的研究早产儿生后Apgar评分与血气分析的相关性,以指导临床对早产儿窒息的诊断及处理。方法用i—STAT型血气分析仪对44例早产儿及36例足月儿生后1、5 min脐动脉血进行血气分析,并与Apgar评分进行相关分析。结果血pH值: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1 min Apgar评分≤7分的有13名,占总数的29.5%;5 min Apgar评分≤7分的有7名,占总数的15.9%;足月儿1 min和5 min Apgar评分≤7分的共有3名,占总数的8.3%。结论诊断早产儿窒息时应将Apgar评分与脐动脉血气值相结合,且以脐动脉血气结果为主。
Objective To study the relationship between Apgar score and blood gas analysis after premature infants to guide the clinical diagnosis and treatment of apnea in premature infants. Methods Blood samples were obtained from 44 preterm infants and 36 full-term umbilical arterial blood samples at 1 and 5 min after birth by i-STAT blood gas analyzer. Correlation analysis was performed with Apgar score. Results The blood pH value was 7.24 ± 0.04 in preterm children and 7.22 ± 0.04 in term children. Apgar score: In the preterm group, there were 13 cases with 1 or 7 min Apgar score ≤7, accounting for 29.5%; 7 with 5 min Apgar score ≤7, accounting for 15.9% of the total; A total of 3 Apgar score ≤ 7 points, accounting for 8.3% of the total. Conclusion Apgar score should be combined with umbilical artery blood gas value in the diagnosis of asphyxia in preterm infants, and the results of umbilical arterial blood gas are the main factors.
