title: [Prognostic value of cardiotocograms during labor evaluated with Fisher's index in prediction of fetal acidosis].
abstract: The cardiotocography beside ultrasonography plays fundamental role in supervision of fetal well-being during gestation and labour. There were performed an analysis of 32 labour cardiotocograms according to Fisher and referred them to pH of fetal umbilical vein. There were proved high significant statistical relation between Fisher's index and pH p = 0.0002 (r = 0.61) and BE p = 0.0006 (r = 0.47) umbilical vein blood. In prediction of fetal acidosis the value of Fisher index in pH < or = 7.25 and described the sensitivity 100%, false positive 72.7%, false negative 0% and accuracy 75%. Obtained date do not differ from those given in literature. The low positive prediction and related with this high percentage of false positive results determine the fault of this indirect method of fetal status estimation.
