滑脉诊断早期妊娠的评价研究

为评价滑脉诊断早期妊娠的临床应用价值,使用脉图仪和病理学方法,同步检测了205例临床诊断为早孕者的脉象和子宫内膜组织。结果在病理学确诊为早孕的196例中,有192例呈现滑脉图象。显示滑脉诊断早期妊娠的准确度为97.6%,灵敏度为97.9%,漏诊率为2.1%,阳性预检值为99.5%,尤登指数为0.868,特异度为88.9%,误诊率为11.1%。反映滑脉测定是诊断早期妊娠高度敏感、便于运用的指标,在我国很有推广使用价值,但其特异性尚不甚理想。

Assessment of Early Pregnancy Detection with Sphygmogram of Smooth Pulse

In order to assess the clinical availability of early pregnancy detection with Sphygmogram ofsmooth pulse, pulse pictures and endometrial tissues were simultaneously examined respectivelywith sphygmograph and pathological method in 205 cases of clinically diagnosed early pregnancy.Among them, 196 cases were pathologically confirmed as early pregnancy, 192 displayed smoothpulse on the Shygmogram. This shows the precision of sphygmogram of smooth pulse in detectingearly pregnancy was 97.6%, its sensitivity 97.9%, Jordan index 0.868, speificity 88.9%, and mis-diagnosis 11.1%. Though its specificity was not quite satisfactory, sphygmogram of smooth pulse hasproved to be a sensitive index with high precision and easy management. Therefore, it is well worthto be popularized in China.
