B超测定胎儿肱骨头皮下软组织厚度与新生儿体重关系的研究

Study on the correlation between the thickness of soft tissue of humerus head of fetus detected by B ultrasound and neonate weight

目的 探讨B超测定足月胎儿肱骨头皮下软组织厚度在预测新生儿体重方面的价值.方法 选择妊娠38～40周正常妊娠妇女478例,产前经腹超声测量胎儿肱骨头皮下软组织厚度、双顶径、股骨长、肱骨长,分析其与新生儿出生体重的相关性.结果 新生儿出生体重与胎儿肱骨头皮下软组织厚度、双顶径、股骨长、肱骨长均呈正相关（r分别为0.729、0.722、0.432、0.341,P＜0.01）.结论 肱骨头皮下软组织厚度与新生儿出生体重呈正相关,相关性较双顶径、股骨长、肱骨长好.

Objective To investigate the value of B ultrasound （B- US） in measuring the thickness of soft tissue of humerus head of fetus in forecasting newborn birth weight. Methods The thickness of the soft tissue of humerus head, biparietal diameter （BPD）, femur length （FL）, humerus length （HL） in 478 normal pregnant women （gestational time：38 ～ 40 weeks） were measured by B-US. The correlation between these parameters and neonate weight was analyzed. Results The parameters were correlated positively with birth weight （ r = 0. 729,0. 722,0. 432,0. 341, respectively, P 〈 0.01 ）. Conclusion The thickness of the soft tissue of humerus head is positively correlated with neonate weight. The correlation is better than BPD, FL, HL.
