目的:探讨纤支镜下大容量肺泡灌洗术在尘肺大咯血患者中的临床应用效果。方法:选取清远市慢性病防治医院2015年1月至2017年1月收治的尘肺大咯血患者26例作为研究对象,采用乱数表法将患者随机均分为对照组和观察组各13例。对照组常规止血;观察组行纤支镜下大容量肺泡灌洗术治疗。结果:对照组患者治疗总有效率为69.2%,观察组患者治疗总有效率为92.3%,观察组治疗总有效率与高于对照组,差异具有统计学意义(P<0.05)。治疗前对照组和观察组患者胸部X线表现相同,治疗后对照组患者胸部X线表现为肺密度无明显变化,两侧光密度不对称,肺部液体残留有所减少;治疗后观察组患者胸部X线表现为肺密度明显降低,与治疗前相比类似白肺,两侧肺光密度对称,肺部无残留液体。结论:尘肺大咯血患者采用纤支镜下大容量肺泡灌洗术治疗临床疗效显著,且胸部X线表现明显改善。
Objective: To investigate the clinical application of bronchofibroscope lavage in patients with pneumoconiosis and hemoptysis. Methods: Twenty-six patients with pneumoconiosis and severe hemoptysis admitted from January 2015 to January 2017 in Qingyuan chronic disease prevention and control hospital were selected as research objects. The patients were randomly divided into control group and observation group with 13 cases in random number table. The control group received conventional hemostasis; the observation group was treated with high-capacity alveolar lavage under fiberoptic bronchoscopy. Results: The total effective rate of the control group was 69.2%. The total effective rate of the observation group was 92.3%. The total effective rate of the observation group was higher than that of the control group. The difference was statistically significant (P <0.05). Before treatment, the control group and observation group showed the same chest X-ray. After treatment, the chest X-ray showed no obvious change in the lung density, asymmetric optical density on both sides, and the residual liquid in the lung decreased. After treatment, the observation group Chest X-ray showed a significant reduction in lung density, compared with white lungs before treatment, both sides of the lung optical density symmetry, no residual fluid in the lungs. Conclusion: Patients with pneumoconiosis and hemoptysis underwent bronchofibroscopy with large-volume alveolar lavage showed significant clinical effect and chest X ray performance was significantly improved.
