目的:探讨动脉血乳酸水平与新生儿窒息的相关性。方法:随机选择2012年收治的71例窒息足月新生儿为对象,依据Apgar评分分为轻、重度窒息两组,另选取正常足月新生儿45例为对照组,对动脉血乳酸进行评价。结果:窒息组血乳酸水平显著高于对照组,差异有统计学意义(P<0.05),且血乳酸水平与窒息程度成正比。结论:早期检测血乳酸水平可作为临床判断新生儿窒息程度的辅助实验室指标,可弥补Apgar评分在诊断新生儿窒息中的不足,对指导治疗具有十分重要的意义。 Objective: To investigate the correlation between arterial blood lactic acid level and neonatal asphyxia. Methods: Seventy-two neonates with full-term asphyxia were enrolled in 2012. The patients were divided into mild and severe asphyxia group according to Apgar score, and 45 normal full-term newborns were selected as control group to evaluate arterial blood lactic acid. Results: The level of blood lactate in asphyxia group was significantly higher than that in control group (P <0.05), and the level of blood lactate was directly proportional to the degree of asphyxia. Conclusion: The early detection of blood lactate level may be used as an auxiliary laboratory index to judge the degree of neonatal asphyxia, which can make up for Apgar score in the diagnosis of neonatal asphyxia, which is of great significance for guiding the treatment.
