Bronchoalveolar lavage (BAL) is a diagnostic technique through which information is obtained about conditions in peripheral parts of the bronchoalveolar tree. To determine the impact of general anesthesia on BAL fluid composition, nine patients underwent BAL while under general anesthesia and 16 healthy controls had BAL with local anesthesia. The percentage of recovered fluid and total cell counts were significantly lower in patients under general anesthesia than in controls. The number of viable cells, the proportions of the various cells, and the BAL albumin-serum albumin ratio did not differ between the groups. Thus, general anesthesia with controlled ventilation, as performed in this study, apparently does not seriously after the prerequisites for BAL.
支气管肺泡灌洗（BAL）是一种诊断技术，通过该技术可获取有关支气管肺泡树周边部位状况的信息。为确定全身麻醉对BAL液成分的影响，9例患者在全身麻醉下接受了BAL，16名健康对照者在局部麻醉下进行了BAL。全身麻醉患者的回收液百分比和总细胞计数显著低于对照组。两组之间活细胞数量、各种细胞比例以及BAL白蛋白与血清白蛋白比值并无差异。因此，本研究中所采用的控制通气的全身麻醉，显然不会严重影响BAL的前提条件。
