宫内节育器嵌顿发生的影响因素分析

Analysis on influencing factors ofincarceration of intrauterine device

目的:探索宫内节育器嵌顿的危险因素,为减少宫内节育器嵌顿的发生提供依据。方法:选取2009年3月至2014年5月我院收治的宫内节育器嵌顿患者80例作为病例组,同期门诊80名未发生宫内节育器嵌顿者为对照组,分析宫内节育器嵌顿的相关因素。结果:单因素分析,病例组的痛经发生率(57.5%)高于对照组(38.7%),差异有统计学意义(χ2=5.633,P<0.05);病例组与对照组上环时间差异有统计学意义(χ2=10.569,P<0.01);病例组中妇科炎症发生率(52.5%)高于对照组(26.3%),差异有统计学意义(χ2=12.545,P<0.01);病例组带环怀孕发生率为(58.7%)高于对照组(8.8%),差异有统计学意义(χ2=44.724,P<0.01)。经Logistics回归分析痛经、上环时机、妇科炎症、带环时间和带环怀孕是宫内节育器嵌顿的独立危险因素。结论:在放置宫内节育器前综合考虑妇女的综合状态,选择适宜的宫内节育器,严格遵守放置规程,加强术后观察,可减少宫内节育器嵌顿的发生。

Objectives：To provide scientific basis for preventing incarceration of intrauterine device （IUD） by probing into major causing factors of IUD incarceration.Methods：80 patients that were diagnosed with IUD in-carceration were selected as study group and 80 patients without IUD incarceration as control group,all of who were patients in our hospital from March 2009 to May 201 4.Results：With single factor analysis,the rate of dysmenor-rhea in the study group （57.5%）was higher than that in control group （38.7%）,with statistically significant difference （χ2 =5.633,P 〈0.05）.Difference in the time for IUD incarceration between the study group and the control group was statistically significant （χ2 =1 0.569,P 〈0.01 ）;the rate of gynaecology inflammation in study group （52.5%）was higher than that in control group （26.3%）,with statistically significant difference （χ2 =1 2.545,P 〈0.01 ）.The rate of pregnancy with IUD in study group （58.7%）was higher than that in control group （8.8%）,with statistically significant difference （χ2 =44.724,P 〈0.01 ）.Non -conditioned logistic regression a-nalysis showed dysmenorrhea,the time of IUD insertion,gynaecology inflammation,duration of IUD and pregnancy rate with IUD were all independent risk factors for IUD incarceration.Conclusion：The measures to reduce IUD in-carceration include：consider the female’s overall status before IUD insertion;select appropriate IUD;observe op-erational regulations and strengthen observation after IUD insertion.
