目的:观察宫颈扩张棒在终止12~16周妊娠钳刮术中的应用效果。方法:将2008年1月~2012年10月在我科就诊要求终止妊娠的孕12~16周的妊娠妇女105例随机分为对照组52例和观察组53例,对照组按常规消毒外阴、阴道及宫颈,依次用不同型号金属扩张器,扩张宫颈,直至扩张至10号,行钳刮术。观察2组先选用宫颈扩张棒置于宫颈内4~18小时取出后行钳刮术。观察2组手术时间、术中出血量及术中不良反应。结果:对照组53例患者手术时间为16.07±3.2分钟,观察组52例患者为14.13±3.5分钟;对照组53例患者术中出血量为35.6±11.21ml,观察组52例患者为22.1±6.71ml,;对照组53例患者术中不良反应重度33例(62.3%),中度16例(30.2%),轻度4例(7.4%);观察组52例中不良反应重度9例(17.3%),中度13例(25.0%),轻度30例(57.7%)。经统计学处理,P<0.05,均有统计学意义。结论:应用1次性宫颈扩张棒扩张宫颈取代器械扩张宫颈后行钳刮术,可缩短手术时间,减少术中出血量,减少病人痛苦,使手术更安全有效,可以推广应用。
Objective: To observe the effect of cervical dilatation stick in the pliersion curettage at the end of 12 ~ 16 weeks. Methods: From January 2008 to October 2012, 105 pregnant women aged 12 ~ 16 weeks pregnant in our department who required termination of pregnancy were randomly divided into control group (n = 52) and observation group (n = 53). The control group was routinely disinfected with vulva, Vagina and cervix, followed by different types of metal dilator, dilatation of the cervix until the expansion to No. 10 line clamp curettage. 2 groups were selected first choice of cervical dilation stick placed in the cervix 4 to 18 hours after removal of forceps curettage. Two groups were observed operation time, intraoperative blood loss and intraoperative adverse reactions. Results: The operation time of the 53 patients in the control group was 16.07 ± 3.2 minutes, in the observation group was 14.13 ± 3.5 minutes in 52 patients, in the control group was 35.6 ± 11.21 ml in the 53 patients and in the observation group was 22.1 ± 6.71 in 52 patients ml in the control group, 33 cases (62.3%) were moderate adverse reactions in the control group, 16 cases (30.2%) were moderate and 4 (7.4%) were mild cases in the control group, and 9 cases (17.3% %), Moderate in 13 cases (25.0%) and mild in 30 cases (57.7%). Statistical analysis, P <0.05, were statistically significant. CONCLUSION: One-time cervical dilation stick is an effective method to expand the cervix and replace the cervix with forceps curettage. It can shorten the operation time, reduce the intraoperative blood loss, reduce the pain of patients and make the operation safer and more effective.
