目的：探讨经纤维支气管镜应用冷冻法行儿童支气管异物取出术的有效性及安全性。方法对72例支气管异物的患儿进行纤维支气管镜下应用冷冻治疗仪行异物取出术，并对患儿在术中和术后并发症进行观察。结果所有患儿支气管异物均顺利取出。72例患儿中，术中并发症以一过性低氧血症最常见，共37例，以小年龄组最高，随年龄增大而降低；术后并发症则以咳嗽加重最常见，共20例。术后随访未发现严重并发症。结论纤维支气管镜下应用冷冻治疗仪行儿童支气管异物取出术，虽然具有一定的并发症，但操作时间短，并发症轻微。具有较高的应用价值及安全性。%Objective To explore the effectiveness and safety of fiberbronchoscope combined with cryotherapeatic equipment in treatment of bronchial foreign body in children.Methods 72 children with bronchial foreign body received fiberbronchoscope combined with cryotherapeatic equipment, then the complications were observed during and after the operation.Results Bronchial foreign bodies were successfully removed in all the patients. Among the 72 cases, transient hypoxia was the most common complication during the operation which happened in 37 cases and most occurred in the small age group, and decreased with the age increasing; cough or worsening of cough was the most common complication after the operation which happened in 20 cases; No serious complications were found during the follow-up.Conclusion Although it has some complications when bronchial foreign body received the fiberbronchoscope combined with cryotherapeatic equipment, but the operation time is short, and the complication is mild. It has great application value and security.
