冷冻治疗是医学领域中日趋广泛应用的新疗法,国内外已高度评价其疗效及安全性。几年来,本院在使用液氮冷冻治疗慢性宫颈炎时。干治疗结束后,大部分病人即刻有面颈部潮红及发烧感,一般持续10分钟左右逐渐减轻、消失。个别病人可出现心慌、心跳、哮喘等,其中发生严重反应者5例(见附表),现报道如下。此5例均在冷冻治疗结束后2～20分钟内发生反应,其中3例进行了处理,2例自然恢复。其反应规律是:先有面颈部潮红及自觉发烧、头昏,继之面色苍白、心慌、脉搏变慢、血压下降(例5上升)。究其原因,与冷冻刺激宫颈局部感受器,神经冲动经传入神经传到中枢,引起植物神经系统调节机能发生变化 Cryotherapy is a new and increasingly applied therapy in the field of medicine, and its efficacy and safety have been highly evaluated at home and abroad. In recent years, the hospital in the use of liquid nitrogen cryotherapy for chronic cervicitis. After the treatment is over, the majority of patients instantly have face-to-face flushing and fever, which generally lighten and disappear for about 10 minutes.
