经对292例正常胎儿枕额径和双顶径的外测量,结果表明,枕额径和双顶径都随着胎龄的增长而增大,但其生长速度则随着胎龄的增长而逐渐减慢。经回归分析原理,分别得出预测方程。枕额径增长的速度和双顶径增长的速度没有明显差异(P>0.05)。
The results of measuring the sleeper frontal diameter and biparietal diameter of 292 normal fetuses showed that both the sleeper frontal diameter and biparietal diameter increased with the increase of gestational age, but the growth rate increased with the increase of gestational age Gradually slow down. The regression analysis principle, respectively, to predict the equation. There was no significant difference in the rate of increase in the volume of the pillow and the speed of biparietal diameter growth (P> 0.05).
