目的:探讨超声引导下成人气管异物钳用于宫内节育器取出困难的效果。方法:宫内节育器取出困难者90例随机分为3组,超声引导下气管异物钳组(A组)、长弯血管钳组(B组)、多功能取环钳组(C组),每组30例,比较3组扩宫率、手术时间、出血量、手术费用、器械成本、VAS评分、满意度评分。结果:A组扩宫率、VAS评分低于B,C组(P<0.05),手术时间较B,C组短(P<0.01),B,C组扩宫率、手术时间比较差异无统计学意义(P>0.05),B组VAS评分高于C组(P<0.05);B组出血量较A,C组多(P<0.05),A,C组比较差异无统计学意义(P>0.05);A组取器费用、器械成本高于B,C组(P<0.05);A组满意度评分高于B组(P<0.05),与C组比较差异无统计学意义(P>0.05),B,C组比较差异无统计学意义(P>0.05)。结论:超声引导下气管异物钳用于宫内节育器取出困难尤其适用于使用新型宫内节育器妇女和未生育妇女,但需考虑患者经济能力。 Objective: To investigate the effect of ultrasound-guided tracheal foreign body forceps on the removal of intrauterine devices. Methods: Ninety patients with intrauterine device removal were randomly divided into three groups: ultrasound - guided tracheal foreign body forceps group (A group), long vascular clamp group (B group), multifunctional loop forceps group (C group) Each group of 30 cases, comparing three groups expansion rate, operation time, blood loss, operation costs, equipment costs, VAS score, satisfaction score. Results: The rate of group expansion in group A was lower than that in group B and C (P <0.05), and the operation time was shorter than that in group B and C (P <0.01). There was no statistical difference in the rate of expansion and the operation time in group B and C (P <0.05). The VAS score of group B was higher than that of group C (P <0.05). The bleeding volume of group B was more than that of group A and C (P <0.05), but there was no significant difference between group A and C (P> 0.05). The cost of equipment and equipment in group A were higher than those in group B and C (P <0.05). The score of satisfaction in group A was higher than that in group B (P <0.05), but there was no significant difference between group A and group C > 0.05). There was no significant difference between B and C groups (P> 0.05). CONCLUSIONS: Ultrasound-guided tracheal foreign body forceps for intrauterine device removal is particularly suitable for women using new IUDs and non-fertile women, but needs to consider the patient’s financial viability.
