巨大儿产前超声快速预测方法的探讨

摘要

目的：应用腹围（AC）、股骨软组织厚度（FSTT）、双顶径（BPD）、股骨长（FL）等多项超声指标快速预测巨大儿，减少巨大儿对母婴的影响，以更好地服务于临床。方法：选取单胎孕妇581例，将超声仪器自带公式预测巨大儿结果作为对照组，综合采用AC、FSTT、BPD、FL等多项参数指标预测巨大儿结果作为实验组，比较两组方法的实际符合率。结果：实验组对581例新生儿体重预测符合率及对35例巨大儿体重预测符合率均明显高于对照组，差异具有统计学意义（P＜0.05）；单项指标预测符合率中，AC及FSTT符合率较高于BPD及FL，差异具有统计学意义（P＜0.05）。结论：综合采用AC、FSTT、BPD、FL等多项参数指标预测新生儿体重，其操作简单、快速、准确，可客观反映巨大儿的预测指标，减少巨大儿的并发症，值得推广应用。%Objective:To rapid predict macrosomia by use of various ultrasound indexes such as AC, FSTT, BPD, FL so as to reduce the effect of macrosomia on mother and infant and to provide a better service for clinic. Methods: Five hundred and eighty-one pregnant women with single fetus were selected and the results of macrosomia predicted by an ultrasonic instrument with a formula were taken as a control group and the results of macrosomia predicted by the combination of AC, FSTT, BPD, FL and many other parameters as an experimental group. The actual coincident rate was compared between two groups. Results:The coincident rates of weight prediction in 581 cases of neonatal and 35 cases of macrosomia were obviously higher in the experimental group than in the control group (P<0.05) and the coincident rates of AC and FSTT was slightly higher than that of BPD and FL (P<0.05). Conclusion:The method for the prediction of neonatal weight by the combined use of AC, FSTT, BPD, FL and many other parameters is simple, fast, accurate, can objectively reflect the predictive index of macrosomia and reduce the complications, and is worthy of promotion and application.
