The diagnostic value of ultrasound detection of the fetal middle cerebral artery, umbilical artery blood flow and fetal movement reduction in fetal distress

摘要

Objective: To evaluate the diagnostic value of ultrasound detection of the fetal middle cerebral artery, umbilical artery blood flow and fetal movement reduction in fetal distress. Methods: A total of 30 cases of pregnant women with fetal distress (FIUD) in our hospital were selected as the observation group, and 60 cases of normal pregnant women in the same period were selected as the control group. The fetal umbilical artery, middle cerebral artery resistance index (RI), pulsatility index (PI), the ratio of peak systolic blood flow velocity to end-diastolic blood flow velocity (S/D) and fetal movement reduction were detected. The diagnostic value of the above indicators alone and in combination for fetal distress was observed. Results: The RI, PI and S/D of umbilical artery in the observation group were higher than those in the control group (P0.001). The S/D, RI and PI of the middle cerebral artery in the observation group were lower than those in the control group (P0.01). The number of cases with decreased fetal heart rate in the observation group was significantly higher than that in the control group (P0.001). The area under the curve (AUC) of umbilical artery S/D, umbilical artery RI, umbilical artery PI, middle cerebral artery S/D, middle cerebral artery PI, middle cerebral artery RI, fetal movement reduction and combined above indexes were 0.788, 0.870, 0.847, 0.852, 0.802, 0.658, 0.750 and 1.000 respectively (all P0.05). The combined diagnosis has a higher diagnostic value for fetal distress. Conclusion: Umbilical artery, middle cerebral artery hemodynamics combined with fetal movement has a specific value in diagnosing fetal distress, which is worth of clinical application.
