摘　　要：目的：探讨胎心率监护中短变异（STV）与分娩结局的相关性。方法：本院住院分娩孕妇常规进行无负荷试验（NST）的同时，应用牛津公司8002专家系统进行分析，选择短变异〈5．0ms的孕妇128例，并分为STV〈2．9ms组、STV 3．0～3．9ms组和STV 4．0～4．9ms组；随机选择同期STV〉5．0ms 80例，并对不同STV组与围生儿预后不良和NST异常的分布情况及STV与胎儿附属物异常的关系进行分析和研究。结果：STV 3．0～3．9ms组和〈2．9ms组的NST异常、围生儿预后不良及胎儿附属物异常明显高于STV 4．0～4．9ms组与洲〉5．0ms组（P〈0．05）。结论：STV〈4．0ms与胎儿宫内缺氧等围生儿预后不良和胎儿附属物异常有较好的相关性，它可成为衡量胎心率变异的一个新指标，提高了胎心率曲线判读的准确性。Objective： To study relationship between Short-Term variation （STV） of fetal monitoring and pregnant outcome. Methods： 208 cases of normal delivery in our hospital from Jun. 2002 to Dec. 2004 were investigated. All the cases were examined by Non-stress test （NST） and vibtratory acoustic stimulation test （VAS-T） that be analyzed with Sonicaid system 8002 at the same time. 80 cases with STV 〉 5.0 ms and 128 cases with STV 〈 5.0 ms were chosed and divided into STV 〈 2.9 ms, 3.0～3.9 ms, 4.0～4.9 ms, and 〉 5.0 ms group. The association between STV variation and poor neonatal prognosis, abnormal NST, fetal appurtenances was analyzed. Results： The rate of abnormal NST, the poor prenatal prognosis, and abnormal fetal appurtenances in STV between 〈 2.9 ms and 3.0～3.9 ms groups were higher than those in STV between 4.0～4.9 ms and STV 〉 5.0 ms groups （P 〈 0.05）. Conclusions： There is a better relationship between STV 〈 4.0 ms and fetal distress or intrauterine deaths. STV is not only a new index of fetal heart rate variability and a efficient supplement to estimate CTG by eyeball, but also a impersonal index to foretell the prenatal prognosis and to assistant diagnose abnormal fetal appurtenances.
