钳夹术前软化和扩张宫颈的准备是手术成功的关键。我院用一次性宫颈扩张棒颈管放置加米索前列醇口服做术前宫颈准备74例(A 组),与单用米索前列醇口服74例(B 组)及单用一次性宫颈扩张棒术前颈管放置74例(C 组)进行手术效果比较观察。在宫口扩大、手术时间、子宫收缩、减轻受术者痛苦,以及人工流产综合征发生率等方面,A 组明显优于 B 组及 C 组,经统计学处理有显著差异。实验证明,钳夹术前用宫颈扩张棒缓慢扩张宫口配合口服前列腺素协同作用,可使手术更安全、有效。单用口服米索则可作为人流术前宫颈准备。
Preoperative softening and expansion of the cervix preparation of the cervix is the key to successful surgery. In our hospital, 74 cases (group A) with preoperative cervical preparation of oral misoprostol were placed with a disposable cervical dilator neck tube and 74 cases (group B) orally with misoprostol alone and single-use cervical dilatation Preoperative 74 cases placed in the neck tube (C group) were compared the effect of surgery. In the cervix expansion, operation time, uterine contraction, to reduce the suffering of the surgeon, and the incidence of induced abortion syndrome and other aspects, A group was significantly better than the B group and C group, statistically significant differences. Experiments show that the preoperative use of cervical dilatation of cervical dilation stick slowly expansion of cervix with oral prostaglandin synergy, surgery can make safer and more effective. Single use of oral misoprostol can be used as preoperative flow of cervical preparation.
