Umbilical artery blood flow measurement in term pregnancy Fetal heart monitoring combined prediction of fetal distress
Distress rate of 10% to 20%. Obviously this limit and the status of clinical observation is inconsistent. Chu Hung women in term pregnancy umbilical artery flow S / D value is between 2.5-3.0 children between the perinatal outcome of a text also believe that S / D ≥ 2.5 when the infants were significantly higher than the incidence of adverse outcomes S / D values <2.5 increase. Therefore, we have to umbilical artery S / D value of 2.5 for the 85th percentile line, the study umbilical artery S / D value ≥ 2.5 group was combined fetal heart rate monitoring for fetal distress forecast. The results also confirmed this view. And when combined cord blood flow when fetal monitoring in predicting fetal distress, meaning even more significant, more accurate forecasts. All the weeks, monitor and umbilical artery blood flow with non-invasive fetal heart rate monitoring, simplicity, repeatability advantages. Umbilical artery flow velocity directly from the hemodynamic point of view the situation to determine fetal circulation. A lot of literature, clinical application of this monitoring method has greatly enhanced after the diagnosis of fetal distress. However, obese pregnant women vulnerable to umbilical blood flow, the depth of fetal umbilical artery and other locations, making the graphics is unclear, the validity of umbilical blood flow data; for continuous monitoring of fetal heart rate monitoring fetal heart rate changes in an instant, fetal heart rate more sensitive to hypoxia, reflect fetal hypoxia in time, but vulnerable to a variety of single NST check the situation of interference, such as fetal sleep cycle, maternal position, complications, and drug interference, resulting in false positive, delay treatment, the diagnostic accuracy of J . Reported a variety of both domestic and international joint application, is able to make up for lack of both to improve the accuracy of diagnosis of fetal distress. This set of data is also to make up for the inadequacies of the two, select umbilical S / D value ≥ 2.5 group was no response to United fetal heart rate monitoring for fetal distress rate respectively to understand and neonatal adverse outcomes. According to statistical results show that: both the Joint analysis is more helpful in predicting fetal distress as soon as possible. , In the light, Doppler umbilical artery flow velocity joint determination of fetal heart rate monitoring, can improve the diagnostic rate of fetal distress, which early clinical intervention to take timely measures to provide a more reliable basis. |
