三种软化宫颈方法临床效果评价

Evaluation of Clinical Effects of Three Methods in Softening Cervix

目的：比较昆布条、米索前列醇、宫腔插管三种方法在钳刮术及宫腔镜电切术前软化宫颈的效果。方法：92例行宫腔镜电切术及妊娠11-14孕周需行钳刮术患者,随机分为A、B、C 3组,A组于术前4-5 h宫颈插入昆布条,B组于术前2 h阴道放置米索前列醇0.2 mg,C组于术前12 h宫颈插入橡胶导尿管,比较3组宫颈扩张程度、主观疼痛、术后体温等。结果：A组宫颈扩张成功率（96%）与B、C组（83.3%,86.6%）比较,有统计学意义（P〈0.05）,B组与C组比较无统计学意义（P〉0.05）;主观疼痛平均分值3组无统计学意义（P〉0.05）;术后体温C组分别与A、B组比较,有统计学意义（P〈0.05）。结论：昆布条能安全有效的扩张宫颈。

Objective： To compare the clinical effects of three methods of laminaria tent,misoprostol and intrauterine intubation for softening the cervix before clamp curettage and hysteroscopic resection. Methods： 92 cases of hysteroscopic resection and pregnancy for 11 to 14 weeks that needed to be performed clamp curettage were randomly divided into Group A,B and C. In group A,the laminaria tent was inserted into the cervix 4 - 5 hours before operation; in group B,0. 2mg misoprostol was placed in vagina 2 hours before operation; in group C,urethral catheter was inserted into the cervix12 hours before operation; then the degree of cervical dilatation,subjective pain and postoperative temperature were compared. Results： The success rate of cervical dilatation in group A（ 96%） was significantly higher than that in group B and C（ 83. 3%,86. 6%）（ P〈0. 05）,while there was no significant difference between group B and group C（ P〉0. 05）. The average score of subjective pain was not statistically significant in three groups（ P〈0. 05）. Compared with group A and B,the postoperative temperature of group C was statistically significant（ P〈0. 05）. Conclusion： Laminaria tent can safely and effectively dilate the cervix.
