本文８３例足月新生儿出生即时脐血气分析结果表明，脐血气分析和Ａｐｇａｒ评分有明显相关性，其客观性强、灵敏度高，是Ａｐｇａｒ评分所不及的。本组实际测得的新生儿酸中毒的发生率远较临床发现的胎儿窘迫及新生儿窒息为高。出生时后羊水性状和脐动脉血ｐＨ值亦存在明显的相关关系，脐动脉血ｐＨ值随羊水混浊度增加而下降，而新生儿窒息率相应上升。新生儿窒息而羊水尚清的病例均存在明显的酸中毒，提示脐血气变化更敏感于羊水性状的改变。
In this paper, 83 cases of full-term newborns born in real-time umbilical blood gas analysis showed that the umbilical blood gas analysis and Apgar scores were significantly correlated, its strong objectivity, high sensitivity, less than the Apgar score. The actual incidence of neonatal acidosis measured in this group is far higher than the clinical findings of fetal distress and neonatal asphyxia. Amniotic fluid after birth and umbilical arterial blood pH values also have a significant correlation, umbilical arterial blood pH value decreased with the increase of amniotic fluid turbidity, and a corresponding increase in neonatal asphyxia. Neonatal asphyxia and amniotic fluid clear cases are obvious acidosis, suggesting that changes in cord blood gas is more sensitive to changes in amniotic fluid traits.
