支气管镜检取异物术中血氧饱和度与气道炎症的相关性分析

目的]研究支气管镜检取异物术中血氧饱和度(SaO2)变化与气道炎症的相关性.方法]回顾性研究三组气管、支气管异物患儿的临床资料.A组为合并有气道炎症患儿;B组对照组,为无气道炎症患儿,C组为合并气道炎症但经过连续2 d以上的抗炎治疗.查出3组病例术中从下镜开始至退镜手术结束期间SaO2的最低值并加以比较.结果]A组患儿术中SaO2最低值小于80%的发生率明显高于B组和C组.结论]气管、支气管异物在合并气道炎症的情况下行支气管镜检取异物术,术中容易出现血SaO2下降,建议术前尽可能予以充分的抗炎治疗.

Correlation Analysis Between SaO2 and Airway Inflammation in Removal of Foreign Bodies by Bronchoscopy

Objective]To study the correlation between SaO2 and airway inflammation in removal of foreign bodies by bronchoscopy.Methods]A retrospective research was made for tracheobronchial foreign bodies of children in 2 years,170 patients were divided into 3 groups: group A(n=67) complicated with airway inflammation, group B(n=71) was the control group, without airway inflammation, group C(n=32) complicated with airway inflammation and received 2 days anti-inflammatory treatment, then the minimum SaO2 of all patients was tested in the operation.Results]The rate of SaO2(below 80%) was significantly higher in group A than in group B and group C.Conclusion]SaO2 is prone to decrease in the operation when patients of tracheobronchial foreign bodies are complicated with airway inflammation, and anti-inflammation treatment should be taken preoperatively.
