目的:探讨胎儿电子监护中胎心基线短变异参数的临床界值及意义,评价短变异(STV)与围产儿预后不良的相关性。方法:回顾性分析2009年1～6月对1 216例产妇进行全产程胎心监护,分析监护图形STV值,并对其中296例测脐动脉血pH值,结合分娩时羊水性状、新生儿1 min Apgar评分和围产儿病率分析其相关性。结果:以STV<3.0 ms为界值,预测胎儿酸中毒的灵敏度为59.80%,特异度94.84%,阳性预测值85.92%,阴性预测值81.78%;预测新生儿窒息的灵敏度为52.20%,特异度98.94%,阳性预测值89.62%,阴性预测值92.16%。结论:STV<3.0 ms可以作为临床预测胎儿酸中毒和新生儿窒息的可靠指标,与新生儿1 min Apgar评分、脐动脉血pH值和围产儿预后不良有显著相关性。
Objective: To explore the clinical value and significance of fetal short-term variation of fetal heart rate in fetal electronic monitoring, and evaluate the correlation between short-variant (STV) and poor prognosis of perinatal children. Methods: A retrospective analysis of 1 216 cases of full-term fetal heart rate monitoring of 1 216 women from 2009 to 2009, analysis of STV value of the monitoring graphics, and 296 of which measured the umbilical arterial blood pH value, combined with amniotic fluid during delivery, neonatal 1 min Apgar score and perinatal morbidity analysis of its relevance. Results: The sensitivity of predicting fetal acidosis was 59.80%, specificity of 94.84%, positive predictive value of 85.92% and negative predictive value of 81.78% with STV <3.0 ms as the cutoff value. The sensitivity of prediction of neonatal asphyxia was 52.20% 98.94%, positive predictive value 89.62%, negative predictive value 92.16%. CONCLUSIONS: STV <3.0 ms can be used as a reliable indicator for predicting fetal acidosis and neonatal asphyxia, which is significantly related to Apgar score at 1 minute, umbilical arterial blood pH and poor prognosis in perinatal infants.
