目的:探讨纤支镜下灌洗在气管切开后肺部严重感染中的治疗效果。方法:对68例气管切开合并严重肺部感染在全身用药的基础上行支气管肺泡灌洗,每周2~3次,观察其临床改善情况及病程。结果:有效62例,无效6例,血气恢复正常52例,22例意识不清经1~2次支气管灌洗意识转清,无一例严重并发症,有效率91.2%。结论:支气管肺泡灌洗有助于控制肺部感染,纠正呼吸衰竭,疗效显著安全,值得推广。 Objective: To investigate the therapeutic effect of bronchofibroscopy in the severe pulmonary infection after tracheotomy. Methods: 68 cases of tracheotomy combined with severe pulmonary infection were treated with bronchoalveolar lavage on the basis of systemic administration, 2 to 3 times per week, and the clinical improvement and course of disease were observed. Results: 62 cases were effective, 6 cases were ineffective, 52 cases were normal blood gas recovery, 22 cases were unconsciously cleared by bronchoalveolar lavage 1 or 2 times without any serious complication, the effective rate was 91.2%.
