目的 :寻找行纤维支气管镜小儿气道内异物摘取术中简易的供氧方法。方法 :应用纤维支气管镜附加外导管并行介入供氧。结果 :对 6 1例小儿气道内异物进行摘取术 ,取得良好效果 ,术前术中术后用血氧计监测SaO2 (血氧饱和度 ) ,其值波动不超过 4%。除 1例因异物较大钳取通过声门裂时脱落 ,行气管切开取出异物外 ,其余 6 0例均获成功。结论 :为纤维支气管镜行小儿气道内异物摘取寻找到了一个安全、可行、简易的供氧方法。 Objective: To find a simple method of oxygen supply in the removal of foreign body in children with bronchoscopy. Methods: Additional fiberoptic bronchoscopy with external catheter interventional oxygen. Results: Totally 6 1 cases of foreign body airway removal were performed well, and SaO2 (oxygen saturation) was monitored by oximeter after operation before and after surgery. Its value fluctuated no more than 4%. Except for one case, the other 60 patients were successfully surgically removed due to the detachment of the foreign objects through the glottis, the removal of foreign bodies by tracheotomy. Conclusion: This study found a safe, feasible and simple method of oxygen supply for foreign body in children with bronchoscopy.
