目的研究经纤维支气管镜插管介导肺泡灌洗治疗急性肺脓肿的临床效果。方法67例肺脓肿患者分成两组，对照组给予常规药物治疗。治疗组34例，在对照组治疗的基础上加用经纤支镜肺泡灌洗、局部给药。结果治疗组与对照组治愈率、总有效率两组差别均有显著统计学意义，p＜0.05。结论在对患者进行全身治疗的基础上，采用经纤维支气管镜吸痰、肺泡灌洗及改良注入药物治疗，取得了很好的临床效果，总有效率97.05％。且该改进方法总有效率较既往报道有提高。“,” Objective:To invesigate the clinical efficacy of treating acute pulomonary abscess patients using Bronchoalveolar lavage by branchofiberoscope combined with local drug injection.Methods: sixty-seven patients of pulmonary abscesses were randomly divied into two trial groups. Control group(n=33),using routine medications only,treatment group(n=34),using bronchoalveolar lavage by branchofiberoscope combined with local drug injection on the basis of the comprehensive treatment.Results:comparing with two trial groups, curing rates and total effective rates were significantly different(p<0.05).Conclusion:It is significantly clinical effieacy to use a combination of suctioning,bronchoalveolar lavage and local drug injection by bronchofiberoscope on the basis of the comprehensive treatment.total effective rates 97.05%.comparing with review the literature,total effective rates of the therapeutic method were raised.
