Abstract:

Bronchoscopic ablative therapy, which is mainly used in airway obstructive diseases, includes laser，thermo-coagulation（electrocautery，and argon plasma coagulation） and cryotherapy. The thermal ablation and frozen cut can quickly destroy the obstructions in the airway，such as the granulation tissue，scar tissue and tumors. In the meanwhile，the freezing and thawing technique can effectively inhibit the granulation tissue and scar tissue regeneration. Timely，standardized and integrated application of bronchoscopic ablation is the key to gaining the safe and effective treatment in children with severe airway obstructive diseases.

Key words: laser, electrocautery, argon plasma coagulation, cryotherapy, flexible bronchoscopy, child

摘要：

儿童气道消融术主要包括热消融术和冷冻治疗术，其中热消融术包括激光、高频电凝切、氩等离子体凝固等。气道消融术主要应用于气道阻塞性疾病，如肉芽组织增生、瘢痕增生及肿瘤等。热消融术及冻切术可快速畅通气道，用于严重气道阻塞的治疗；冻融术可破坏局部组织及血供，可有效抑制肉芽组织及瘢痕再生。适时、规范地综合应用气道消融术是安全有效治疗的关键。
