探讨测量宫颈长度在预测早产中的意义

目的：探讨超声测量宫颈长度以评价早产发生的可能性。方法：选择有早产先兆的孕妇312例，经会阴超声测量宫颈长度，并追踪其妊娠结局。结果：经过检测，发现312例孕妇中有69例早产，且69例中有54例宫颈长度小于3 cm，发现随宫颈缩短，早产发生率上升。并且设定3 cm为临界值具有临床意义。结论：超声测量宫颈对预测早产具有一定意义，并且无创、简单、可重复操作。

To Evaluate the Predictive Value of Cervix Cervical Length Detected by Ultrasonography for Premature Delivery

Objective：To objective the probability forecast that happen to premature delivery by estimating cervecal length of the ulstrasound. Method：The 312 patients with threatened premature labor were examined by estimating cervecal length of the ulstrasound. The cervical length and pregnancy outcome were recorded and analyzed.Result：After detection,in the 312 patients,69 cases were born prematurely and 54 cases of them cervical length were less than 3 cm.and we found that it had therapeutic value to set 3 cm as the threshold limit value.Conclusion：Cervical length in the prediction of preterm delivery in patients who has preterm symptoms is a certainly significance,and it measures atraumaticly,simply and repeating.
