摘要 目的:探讨双胎孕妇宫颈长度与早产的关系,为临床诊断早产提供新的方法。方法:对2002年6月~2009年6月产前检查的双胎孕妇286例行会阴超声检查测定宫颈长度,以资料完整的147例为研究对象,并追踪其分娩结局,研究它与早产的关系。结果:①正常组平均宫颈长度(3.32±0.51)cm,早产组平均宫颈长度(2.41±0.69)cm,差异有统计学意义(P<0.01);先兆早产组平均宫颈长度(2.86±0.72)cm,与正常组相比差异有统计学意义(P<0.05)。②宫颈长度与早产及先兆早产的发生呈负相关(r=-0.92),宫颈长度>3.0cm早产发生率为11%,宫颈长度≤3.0cm早产的发生率明显增加,宫颈长度<2.0cm早产发生率达88%,宫颈长度≤3.0cm出现早产症状的相对比明显增加。结论:超声测量双胎孕妇宫颈长度结合临床预测早产具有一定临床价值。
