摘　　要：目的：探讨胎儿脐动脉的S／D值与孕龄的关系，把东北与西南地区的S／D值对照，探讨两地的S／D值是否有差异。方法：将东北地区714例和西南地区642例末次月经明确、平时月经规律的正常妊娠的孕妇，孕龄为20周-42周，每4周为一组，将其脐动脉的S／D值加以记录，计算出每组孕龄的S／D值范围，得出孕龄与S／D值的对应关系，并将两地的S／D值范围对照，验证两地脐动脉S／D值是否具有差异。结果：随着孕龄的增加脐动脉的S／D值呈下降趋势，两地之间正常胎儿的S／D值无差异性，P〉0．05。结论：脐动脉的S／D值不具有区域性的差异，是一个较客观的指标，对临床具有指导意义。Objective： To investigate the relationship of the systolic/diastolic （S/D） ratio in the umbilical artery and gestation ages of normal fetus and to study the difference of the S/D ratio between the northeast region and the southwest region of China. Methods： The lwlationship between the gestation age and the S/D ratio was explored by recordding the S/D ratio of 714 norreal fetuses in northeast region and 642 eases in southwest region and calculating the range of S/D ratio. The difference of the S/ D ratio between northeast and southwest legion was analyzed by comparing ranges of S/D ratio in two regions. Results： There is no difference in the S/D ratio between two legions and S/D ratio is decreased correspondingly with increasing in gestation age. Conclusion： S/D ratio is a objective index and has a clinical significance.
