小儿气管支气管异物取出术后支气管肺泡灌洗的应用

Application of bronchoalveolar lavage after removing tracheal or bronchial foreign bodies in children

目的 探讨金属支气管镜下小儿气管、支气管植物性异物取出术后支气管肺泡灌洗的疗效。方法 在STORZ支气管镜下取出异物后取气管支气管内分泌物作细菌培养加药敏试验 ,然后进行支气管肺泡灌洗治疗 ,并与 4 0例用同样方法取出异物术后仅行常规全身抗炎治疗的病例 ,进行疗效和疗程时间比较。结果 灌洗组疗程比对照组明显缩短 (P <0 .0 1) ,有统计学意义。结论 异物取出后同时采用支气管道内灌注抗生素 ,可提高局部抗生素浓度 ,促进炎症的吸收好转缩短疗程。

Objective To explore the therapeutical effect of bronchoalveolar lavage (BAL) after removing vegetable foreign bodies in children's trachea or bronchia using a metal bronchoscope. Methods After removal of foreign bodies in trachea or bronchia, we proceeded the germiculture and sensitivity test of antibacterical drugs with secretion in bronchia,then took BAL, and compared to control group of 40 cases treated only by conventional autiinfection drugs without BAL both with effect and period of treatment. Results BAL group was significantly shorter than control group in the period of treatment (P< 0.01). Conclusion Antibiotics could be filled into bronchia by taking BAL after the removal of foreign bodies, BAL could increase the concentration of local antibiotic and accelerate absorption of inflammation, and shorten the therapeutical time significantly.
