本文报告某医院73例宫颈糜烂病人在门诊应用冷冻术治疗的研究。作者介绍了不用麻醉,每周定期施行一次的门诊冷冻术。选用一个适当形状的冷冻探头与宫颈糜烂面相紧贴,采用液氮为冷冻源,使冷冻探头的温度达-190℃在2～3分钟内将两者迅速冻结在一起,直到冰圈超越糜烂面2～3毫米止。再用一个受控制的加热器给于冷冻探头加温,促进冷冻溶解,而使探头从病变处脱离下来。若病变范围过广,冷冻探头不能复盖全部病变时,可采用多次重迭冷冻术。病变愈合时多能超越冷冻的边缘而全部愈合。
This article reports 73 hospital patients with cervical erosion in the clinic application of cryotherapy. The authors describe outpatient cryotherapy that is performed on a weekly basis without anesthesia. Select a suitable shape of the frozen probe and cervical erosion surface close to the use of liquid nitrogen as the source of frozen so that the temperature of the freezing probe up to -190 ℃ in 2 to 3 minutes the two quickly frozen together until the ice ring beyond the erosion surface 2 ~ 3 mm only. A controlled heater is then used to warm the cryoprobe to promote freeze-thaw, allowing the probe to detach from the lesion. If the lesion is too wide, frozen probe can not cover all lesions, can be used multiple overlapping cryotherapy. The lesions heal more than frozen edges and all heal.
