远端导管方法与普通方法支气管肺泡灌洗的对比研究

Clinical research of distal bronchoalveolar lavage with plastic tubing and common bronchoalveolar iavage

目的比较远端导管与经负压吸引进行普通支气管肺泡灌洗这两种方法对支气管肺泡灌洗的回吸收量、操作过程及并发症的影响。方法选择2008年5月至12月在我院呼吸内科需要进行支气管肺泡灌洗检查的住院或门诊患者，随机分为两组，普通支气管肺泡灌洗组56例，远端导管支气管肺泡灌洗组66例，观察回吸收量，操作失败率和合并症的发生。结果远端导管支气管肺泡灌洗组的回吸收率超出普通支气管肺泡灌洗组5．55％，操作失败率低于普通支气管肺泡灌洗组9．19％，合并症发生率低于普通支气管肺泡灌洗组7．41％。结论基于上述结果，我们推荐应用导管支气管肺泡灌洗来取代普通支气管肺泡灌洗。

Objective To assess whether distal bronchoalveolar lavage（DBAL） with plastic tubing allowed recovery of more fluid in comparison with common bronchoalveolar lavage（CBAL）, and whether tubing had a favorable impact on operative procedure and complications. Methods A randomized study was performed in the hospital. Patients scheduled for BAL were randomly assigned to DBAL （ n = 66） and CBAL （ n = 56） group. Results In DBAI. group,5.55G more fluid was recovered,9.19G fewer technical failures, and 7.41% fewer complications were recorded. Conclusions Based on these results, we recommend performing DBAL using plastic tubing to replace CBAL.
