目的探讨阴道液HCG与pH定性检测在诊断胎膜早破中的应用价值。方法选取2011年8月至2012年8月淮安市第二人民医院妇产科收治的胎膜早破患者78例,分别对其阴道液进行HCG与pH定性检测。结果阴道液HCG定性检测与pH检测的灵敏度分别为97.00%、96.34%,差异无统计意义(P>0.05),在检测的准确度、阳性预测值以及特异性上有一定的差别,同时阴道液HCG检测效果优于pH检测,但两种方法联合使用具有较好的效果。结论阴道液HCG与pH定性检测均是胎膜早破的检测手段,且这两种方法简单易行,创伤小,联合检测特异性及准确率高。
Objective To investigate the value of qualitative detection of vaginal fluid HCG and pH in the diagnosis of premature rupture of membranes. Methods Seventy eight patients with premature rupture of membranes who had been admitted to Obstetrics and Gynecology Department of Second People ’s Hospital of Huai’an from August 2011 to August 2012 were tested for HCG and pH qualitatively. Results The sensitivities of qualitative and pH detection of HCG in vaginal fluid were 97.00% and 96.34%, respectively, with no significant difference (P> 0.05). There was a certain difference in accuracy, positive predictive value and specificity between vaginal fluid and vaginal fluid HCG test results better than pH test, but the combination of the two methods have good results. Conclusion The qualitative detection of HCG and pH in vaginal fluid are the means of detection of premature rupture of membranes. Both methods are simple and easy to operate with less trauma, higher specificity and accuracy.
