摘要
要求手术人工流产的部分妇女宫颈弹性差,在术前应行充分的宫颈准备以减少手术操作的难度和宫颈损伤。宫颈准备的方法较多,其中天然海藻制成的海藻棒属于亲水性宫颈扩张器,置入宫颈管后其吸收宫颈分泌物中的水分而膨胀,与此同时可逐渐缓慢地扩张宫颈管,促宫颈成熟。很多研究表明,海藻扩张棒能很好地达到人工流产术前扩张宫颈的目的,可能优于米非司酮等药物扩张、金属扩张棒和人工合成扩张棒的效果,且不增加子宫穿孔、感染和过敏等不良反应。使用包括海藻扩张棒在内的各种宫颈扩张方法一定要按需要选择,以免增加受术者不必要的等待时间和额外的医疗负担。
Some of the women whowill experience surgical abortion were found the poor flexibility of cervices,so adequate cervical preparation before surgical abortion is necessary.Adequate cervical preparation can reduce the difficulty of surgical operations and reduce the incidence of cervical injuries markedly.There are many cervical dilation methods.One of the methods is osmotic dilators such as laminaria,made of natural seaweed.When the laminaria is placed into the cervical canal,it will absorb water of the cervical secretions and expand gradually.At the same time,cervical canal will be expanded and ripened softly.Many studies have shown that laminaria can achieve a good role to expand cervical canal abortion before surgical abortion and its effectiveness maybe superior to drugs such as mifepristone,the metal dilators and synthetic osmotic dilators.The evidences have also shown that the laminaria does not increase uterine perforation,infection,anaphylaxis and other adverse reactions.Cervical dilatation method,including laminaria,must be used for those women who really need and also must be informed-choice by the women themselves to avoid unnecessary waiting time and additional medical burden.
