摘要:
目的 研究纤支镜肺泡灌洗在脑死亡边缘性供肺维护中的作用。 方法 选取昆明医科大学附属甘美医院2017年9月至2019年12月收治的符合纳入标准的脑死亡患者，按照随机分组原则，在常规维护的基础上，分为纤支镜肺泡灌洗组（实验组）及对照组，通过2组胸片、动脉血气（氧合指数）、纤支镜检查等指标的比较，进行统计学分析。 结果 2组实验后氧合指数、胸片、纤支镜镜下表现评分均低于实验前评分，差异具有统计学意义（P < 0.05），且2组试验后有效率比较差异有统计学意义（P < 0.05），实验组有效率大于对照组。 结论 纤支镜肺泡灌洗可以作为一种有效维护供肺的技术，是提高边缘性供肺利用的有效手段。 Abstract:Objective To investigate the effect of bronchoscopic alveolar lavage on the maintenance of borderline donor lung in brain death. Methods The brain death patients meeting the inclusion criteria and admitted to Ganmei Hospital of Kunming Medical University from September 2017 to December 2019 were randomly divided into the fiberoptic bronchoscopy alveolar lavage group （experimental group） and the control group on the basis of routine maintenance. Statistical analysis was carried out through the comparison of chest film, arterial blood gas （oxygenation index）, fiberoptic bronchoscopy and other indexes between the two groups. Result The scores of oxygenation index, chest radiograph and fiberbronchoscope performance of the two groups after the experiment were all lower than those before the experiment the differences were statistically significant （P < 0.05）, and there was statistically significant difference in effective rate between the two groups （P < 0.05）. The effective rate of the experimental group was higher than that of the control group. Conclusion Fiberbronchoscope alveolar lavage can be used as an effective technique to maintain the donor lung and has a wide application prospect. -
