多功能子宫腔探测喷灌器制作与临床应用的研究

Study about making and clinical application on the device to spray liquid into uterine cavity and detectthe depth of it

目的探讨多功能子宫腔探测喷灌器的研制及临床应用效果。方法采用随机分组方法将600例研究对象分为三组，每组200例，应用多功能子宫腔探测喷灌器喷灌麻醉药物为I组；宫旁注射浸润麻醉为Ⅱ组；术前不用任何药物直接行人工流产术为Ⅲ组。比较三组手术时扩张子宫颈的疼痛程度、吸刮子宫腔时的疼痛程度、术中的出血量、术中无阻力通过宫颈口扩张器的号数。结果术中扩张子宫颈的疼痛程度I组、Ⅱ组均轻于Ⅲ组（P均〈0．01），I组、Ⅱ组间差异无统计学意义（P〉0．05）；吸宫时的疼痛程度I组轻于Ⅱ组、Ⅲ组（P均〈0．05），Ⅱ组与Ⅲ组间差异无统计学意义（P〉0．05）；术时出血量三组比较差异无统计学意义（P〉0．05）；术中无阻力通过宫颈口扩张器的号数I组、Ⅱ组少于Ⅲ组（均P〈0．05），I组与Ⅱ组间差异无统计学意义（P〉0、05）。结论临床应用多功能子宫腔探测喷灌器喷灌麻醉药物，具有麻醉作用快、镇痛作用强、术中用药、经济、实用、安全、有效等优点。是值得临床推广的新器械。

Objective To evaluate the effectiveness of the device to spray liquid into uterine cavity and detect the depth of it. Methods 600 patients were randomized into three groups with 200 cases each. Group Ⅰ received anesthetics with the device to spray liquid into uterine cavity and detect the depth of it. Group Ⅱ received anesthetics by injecting anesthetics at the side of uterine cervix, Group Ⅲ were not treated with any anesthetics. The degree of pain during enlarging uterine cervix and uterine curettage, the amount of bleeding and the sizes of cervical dilator through uterine cervix with non - resistance were compared between the three groups. Results A significantly alleviated degree of pain during enlarging uterine cervix was observed between group Ⅰ , group Ⅱ and group Ⅲ （ P 〈0. 05 ） , but there was no significant difference in group I and group Ⅱ （ P 〉 0. 05）. A significantly alleviated degree of pain during uterine curettage was observed between group I and group Ⅱ , group Ⅲ （ P 〈 o. 05 ） , but there was no significant difference in group Ⅱ and group m （ P 〉 0. 05）. The amount of bleeding in three groups were not observed（ P 〉 0.05 ）. The significantly decreased sizes of cervical dilator through uterine cervix with non - resistance were observed between group I , group Ⅱ and group m （ P 〈 0. 05 ）, but there was no significant difference in group I and group Ⅱ （ P 〉 0. 05 ）. Conclusion The device to spray liquid into uterine cavity and detect the depth of it is applied in clinic,and it has some advantages： nareotism is quick; abirrition is strong; using is convenience; damage is small;application is economical and safety. So it is worthy of widely use.
