It is necessary controls to apply the method in stage of this complication in good-time. There were below 10% of immature children in 405 high risk patients and only 1,2% to 1500 g.

在使用由有机玻璃制成的新型迈尔-林格 pessary 取得非常好的效果后，作者将这种“无血宫颈环扎术”作为其所在地区（18 万居民）所有即将早产患者的首选方法。有必要及时在该并发症阶段应用该方法进行对照。在 405 例高危患者中，未成熟儿比例低于 10%，体重低于 1500 克的仅占 1.2%。他们成功地将分娩推迟到更有利的时间，显著缩短了住院时间和无能力状态。围产期死亡率也受到了有利影响。详情见表。
