胎心率电子监护(FHR)在我国临床应用已有十年之久,它协助临床尽早发现高危妊娠胎儿在宫内有无缺氧等情况,了解胎儿在宫内的安危起到重要作用,从而挽救了不少临危的胎儿.但在应用过程中发现监护结果有时与临床不尽相符,出现假阳性时增加不必要的剖宫产,假阴性又可能导致延误处理.因此,必须对监护图形进行较细致的观察,以便通过图形的分析尽可能找出较准确的预测标准.国外学者已提出多种胎心率监护评分法,可以较准确地对胎儿情况进行预测.胎心率监护可分:无应激试验(NST),即在无宫缩情况下进行监护;宫缩应激试验(CST)其中包括OCT.NST 的评定标准主要为反应型和无反应型两种.
Fetal heart rate electronic monitoring (FHR) clinical application in our country for ten years, it helps early detection of high-risk fetus in pregnant women with or without intrauterine fetal hypoxia and so on, to understand the safety of the fetus plays an important role in the womb, which Save a lot of critically ill fetuses.But in the application process found that the guardianship results sometimes do not match with the clinical, false positive increase unnecessary cesarean section, false negative may lead to delay treatment.Therefore, the guardianship graphics must be carried out More detailed observation, in order to find out more accurate prediction standard through the analysis of graph.Foreign scholars have proposed a variety of fetal heart rate monitoring score method, you can more accurately predict the status of the fetus.Fatter heart rate monitoring can be divided into: No stress test (NST), that is, no contractions in the case of monitoring; contractions stress test (CST) including OCT.NST assessment criteria are mainly reactive and non-reactive type.
