초음파를 이용한 태아체중 예측 = Ultrasonic Fetal Weight Prediction

다국어 초록 (Multilingual Abstract)

Sonographic measurements of biparietal diameter(BPD), head circumference(HC), abdominal circumference(AC), femur length(FL), were made in 56 cases of pregnant women who deliveried within 72 hours of measurement, using real-time systems with 3.5㎒ transducers. Estimation of fetal weight was calculated by application of equation proposed by Shepard et al and Hadlock et al. Actual birth weights were compared with predicted value
The results were as followings
1. Correlation between estimated and actual fetal wight was very significant.(P<0.0001)
2. The mean of absolute difference for estimated and actual weight was smallest for equation 2 (BPD, AC, FL) with 170gm and largest for equation 4 (AC, HC, FL) with 208gm.
3. Using each equation, the calculated estimated fetal weight fallen within ten percentile range compared to actual birth weight was highest at equation 3(BPD, AC, HC, FL) for 92.9%.
4. Analysing mean residual between estimated and actual fetal weight by according to weight distribution, 3500-3999gm group showed underestimation.
5. In near term pregnant women, when BPD measurement is inaccruate and sometimes cannot be obtained easily. In this cases, with use of AC and FL to calculated estimated fetal weight which are acceptable and reliable.
