目的　研究纤维支气管镜 (FB)在小儿呼吸道疾病临床诊断、治疗价值及其安全性。方法　对我院儿科1993～ 1998年行FB检查的 93例进行回顾性分析。在FB检查的全过程中均采用持续心电及经皮血氧饱和度监测 ,并持续供氧。观察FB检查的临床效果及术后 2 4h内患儿病情的变化。结果　FB检查在小儿呼吸道疾病诊断的阳性率明显高于影像学和临床诊断 (P <0 .0 1) ;其并发症的发生率较成人多见 ,年龄越小 ,并发症越多见 (P <0 .0 5 ) ,全麻组并发症的发生率高于局麻组 (P <0 .0 5 )。结论　FB在呼吸道疾病的病因诊断和疗效观察上有重要价值。只要掌握指征 ,合理应用 ,可减少并发症的发生 Objective To study the value of fibrobronchoscopy (FB) in diagnosis and treatment of pediatric respiratory diseases and its safety. Methods A retrospective analysis of 93 cases of pediatric pediatrics in our hospital from 1993 to 1998 was performed. In the whole process of FB examination are used to monitor continuous ECG and percutaneous oxygen saturation, and continuous oxygen supply. Observe the clinical effect of FB examination and the change of the illness in children within 24 hours after operation. Results The positive rate of FB examination in pediatric respiratory disease was significantly higher than that of imaging and clinical diagnosis (P <0.01). The incidence of complications was more common in adults than in adults. The younger the age, the more complications (P <0. 05). The incidence of complications in general anesthesia group was higher than that in local anesthesia group (P <0.05). Conclusion FB has important value in the diagnosis and treatment of respiratory diseases. As long as the indications, reasonable application, can reduce the incidence of complications
