现代产科常需超声波测心脏状态。多基因遗传中,5%高危新生儿有心脏发育不正常。阳性家族史是常见需测心脏的指征。其他需测胎儿心脏的指征有:(1)免疫性水肿胎儿。(2)反复及持续的胎儿心律不齐。(3)母糖尿病。(4)可疑心脏大小或发育异常。在测量时常有以下几个问题:(1)超声者只能根据看到的心脏测量的二个平面。这些测量能否作心脏大小的指标?(2)心脏大小与胎儿体重、双顶径、腹围、股骨长度及孕龄有何关系?本文分析胎心周径与双顶径、腹围、股骨长度、孕龄及估计胎儿体重间的关系。本文测138例单胎妊娠,18～42孕周,用实时
Modern obstetrics often require ultrasound to measure cardiac status. Multi-genetics, 5% of high-risk neonatal cardiac dysfunction. Positive family history is a common indication of the heart to be measured. Other indications for measuring fetal heart are: (1) immune edema fetus. (2) repeated and persistent fetal arrhythmia. (3) mother diabetes. (4) suspicious heart size or dysplasia. In the measurement often have the following questions: (1) Ultrasound can only be measured according to the heart to see the two planes. Can these measurements be used as an indicator of heart size? (2) What is the relationship between heart size and fetal weight, biparietal diameter, abdominal circumference, femur length and gestational age? Length, gestational age and estimated fetal weight relationship. This article measured 138 cases of singleton pregnancies, 18 to 42 gestational weeks, with real-time
