摘要
对700例正常孕妇的胎儿脐动脉血流指标（S／D、PI、RI）的变化及其与胎儿宫内发育迟缓（IUGR）的相关性进行了分析。结果表明：低体重儿组各孕周S／D均大于正常体重组。S／D增高时，发生IUGR的相对危险度随之增高。S／D、PI、RI异常时．与较低值组进行方差分析，具有显著性差异（P=0．0000）。S／D、RI与新生儿体重呈负相关．以S／D影响较大，其它因素依次为B-超胎盘分级、PI、RI。
We analyzed seven hundred cases of normal gravida on the fetus umbilical artery blood flow indexes and intrauterine growth retardation (IUGR). The results showed that all of mean S/D per pregnant week in the low weight fetus group were greater than those in normal weight group. When S/D was increased, the danger of suffering IUGR was increased too. The analysis of variance indicated that there was a no-table difference (P = 0. 0000) when S/D,PI and RI were ab-normal and a negative correlation between the indexes and the weight of the newborn, Among them,the S/D exert greatest affection on it, and followed by B-ultrasonic placenta classif i-cation, PI and RI. These findings suggested that we could im-prove the accuracy of the diagnosis much more if a comprehen-sive analysis would be made using its developed indexes with B-ultrasonic placenta classification.
