本文报道120例高危孕妇接受子宫应激试验的情况。作者根据心脏科应用应激测定心脏功能的机理,设计一种子宫收缩应激试验来测定胎盘功能,作为胎儿的监视,特别对于一些高危妊娠病例,称为宫缩应激试验(Contrachon stress test—CST)或催产素挑战试验(Oxytocin Challangy test OCT)。方法:孕妇取半坐位,胎心、胎动及宫缩以特殊记录仪测定并连续记录。先测定15-30分钟作为基础记录,然后静脉滴注催产素。开始滴注剂量为0.5毫单位/分钟,前30例每15分钟滴注速度加快一倍;其余病例每15分钟增加0.5毫单位/分钟,直至10分钟内出现3次强宫缩为止。每周试验一次,有的在引产前再做一次。
This article reports 120 cases of high-risk pregnant women receiving uterine stress test situation. The authors designed a uterine contractile stress test to determine placental function based on the mechanism of cardiological stress measurement of cardiac function, as a monitoring of the fetus, especially for some high-risk pregnancies known as Contrachon stress test- CST) or oxytocin challenge test (Oxytocin Challangy test OCT). Methods: Pregnant women take half sitting, fetal heart rate, fetal movement and contractions measured by a special recorder and continuous recording. First measured 15-30 minutes as a basis for records, and then intravenous oxytocin. The initial dose was 0.5 milliliters / minute. The first 30 cases doubles every 15 minutes. The remaining cases increase 0.5 milliliter / minute every 15 minutes until 3 strong contractions occur within 10 minutes. Test once a week, and some do before induction.
