近年来,我院在应用利凡诺行中期引产中发生宫颈阴道部裂伤6例,现报告如下。 临床资料:本组年龄16～22岁,均为初孕妇,平均产程为16小时15分钟,胎儿娩出前因宫缩差静滴催产素3例。6例均为横裂口,位于宫颈后唇与后穹窿交界处,宫颈外口完整。宫颈与后穹窿交界处横行裂伤4例,宫颈后半部环状撕脱1例,宫颈阴道瘘1例。 本组5例因胎儿胎盘娩出后阴道流血量多而宫缩良好,经仔细阴道检查后确诊;1例产后少量阴道流血未能引起重视而漏诊,自然痊愈后形成宫颈阴道瘘,日后因多次自然流产来诊,经阴道检查发现位于宫颈后唇上约3cm处有一横行瘘口。明确诊断后均于裂伤处做新创面,应用2—0肠线修补,住院5～7天痊愈出院。 讨论:利凡诺中期引产致宫颈阴道裂伤的主要原因为:①羊膜腔注入利凡诺可引起子宫体部收缩
