目前临床用于监测胎儿宫内安危的手段主要包括胎动计数、胎儿电子监护、生物物理评分、胎儿脑电图和多普勒超声等。胎动计数简单但主观性强,胎儿电子监护假阳性率高,生物物理评分操作费时,胎儿脑电图临床使用相对受限,而多普勒超声对于血流的监测如孕妇子宫动脉、胎儿脐动脉、脐静脉、大脑中动脉、腹主动脉、肾动脉、静脉导管等对孕期监测胎儿宫内安危较为简单方便,而目前应用最多的仍是胎儿脐动脉血流的监测。
At present, the means used to monitor the intrauterine safety clinically include fetal movement counting, fetal electronic monitoring, biophysical score, fetal electroencephalogram and Doppler ultrasound. Fetal movement count is simple but subjective, fetal electronic monitoring false positive rate, biophysical score operation time, fetal EEG clinical use is relatively limited, and Doppler ultrasound blood flow monitoring such as uterine artery of pregnant women, fetal umbilical artery , Umbilical vein, middle cerebral artery, abdominal aorta, renal artery, intravenous catheter monitoring of fetal safety during pregnancy is relatively simple and convenient, but currently the most used fetal umbilical artery blood flow monitoring.
