脐动脉血乳酸及pH值测定在胎儿窘迫诊断中的临床意义

摘要

Objective To explore the clinical significance of the measurement of umbilical arterial blood lactate and pH value in the diagnosis of fetal distress.Methods We collected 1024 cases of pregnant women whose pregnancy were more than 36 weeks and all these pregnant women were treated at our hospital from March 2011 to June 2014. Acording to the standard of clinical diagnosis of fetal distress and the abnormal rate of fetal heart,all these patients were divided into case group(fetal distress syndrome)totaling 588 cases and control group(non-fetal distress syn-drome)totaling 436 cases.When the fetus not yet have breathe,we immediately mearured the umbilical arterial blood lactate and pH value and analysised the results.Results The lactate value of case group were higher than the control group,the former group's pH value (<7.20)was significantly increased compared with the after group,and comparing with the control group,the difference has statistically significant(P<0.05).Conclusion The umbilical arterial blood lactate and pH value measurement used in clinical will increase the rate of clinical diagnosis of fetal distress,facilitate early intervention,prevent neonatal asphyxia and help to reduce neonatal mortality.%目的：探讨脐动脉血乳酸及 pH 值测定在胎儿窘迫中的临床价值。方法采集我院2011年3月至2014年6月收治的妊娠大于36周孕妇1024例，按照临床诊断胎儿窘迫标准及胎心监护异常分为研究组（有胎儿窘迫征）588例和观察组（无胎儿窘迫征）436例，在胎儿娩出尚未呼吸前立即行胎儿脐动脉血乳酸及 pH 值测定，并进行结果分析。结果研究组乳酸值较对照组高，pH值＜7．20前组较后组显著增多，与观察组对比，差异有统计学意义（P＜0．05）。结论脐血乳酸及 pH值测定应用于临床将提高临床胎儿窘迫诊治率，便于及早进行干预，预防新生儿窒息的发生，有利于降低新生儿病死率。
