Lamicel是浸渗了硫酸镁(MgSO_4)的聚乙烯醇聚合海绵压缩制成的塞条。此塞条膨胀后形成柔软的海绵。本文目的是研究硫酸镁在Lamicel中是否有作用,并评价妊娠头三个月人流术前子宫颈放置含和不含MgSO_4的合成海绵3～4小时软化宫颈的效果。 87例健康未产妇经门诊检查,入院施行头三个月人流术。其中28例(32%)作过一次或一次以上的真空吸引术,无1例有自发流产或宫颈手术史。45例随机分于Lamicel组(Ⅰ组)或不含MgSO_4的塞条组(Ⅱ组)。Lamicel塞条内含200 mg
Lamicel is a plug made of compressed polyvinyl alcohol sponge impregnated with magnesium sulfate (MgSO 4). This plug is expanded to form a soft sponge. The purpose of this paper is to investigate the role of magnesium sulfate in Lamicel and evaluate the effect of softening the cervix 3 to 4 hours prior to abortion in the cervix with synthetic sponges containing and without MgSO 4 prior to abortion for the first trimester of pregnancy. 87 cases of unhealthy mothers by out-patient examination, admitted to hospital for the first three months of abortion. Among them, 28 cases (32%) had one or more vacuum aspiration, none of them had a history of spontaneous abortion or cervical surgery. 45 cases were randomly divided into Lamicel group (group Ⅰ) or without MgSO 4 plug group (group Ⅱ). Lamicel tampons contain 200 mg
