经支气管镜冷冻技术在呼吸系统疾病的治疗领域已取得了显著的成果。该技术利用低温冷冻的原理，对病变组织进行处理，已逐步在多种呼吸系统疾病诊治中广泛应用，包括冻融与冻切技术。随着支气管镜介入技术的不断进步，冷冻技术的应用范围亦逐渐扩大，其安全性与有效性也得到了提高。文章介绍了经支气管镜冷冻技术及其在儿科介入呼吸病学中的应用，旨在让更多儿科同行了解该技术，在呼吸介入治疗中更有效地应用该技术。

Transbronchoscopic freezing technology has made remarkable achievements in the treatment of respiratory diseases. Transbronchoscopic freezing technology uses the principle of low temperature freezing to treat pathological tissue. This technique has been widely used in the diagnosis and treatment of various respiratory pathological，including freeze-thaw and freeze-cutting techniques. With the development of bronchoscopic intervention technology，the application range of refrigeration technology has gradually expanded，and its safety and effectiveness have also been improved. This review systematically introduced the technique of transbronchoscopic freezing and its application in pediatric interventionarespiratory medicine，aiming to maket more pediatric peers aware of this technology,and apply it more effectively in respiratory intervention treatment.
