Abstract：
Whole lung lavage (WLL) is the first-line treatment for pulmonary alveolar proteinosis. We hypothesized that lung ultrasound (LUS) would guide flooding during treatment in a 15-year-old boy. WLL of each lung consisted of instillation of saline followed by kinesiotherapy and fluid drainage. In the first WLL, the lung was repeatedly flooded until the lavage fluid was clear on macroscopic examination. During this process, LUS was used to visualise lung aeration. In the second WLL, we used LUS signs to guide the lavage volume. The appearance of the fluid bronchogram sign showed that saline infusion could be stopped earlier than in the first lavage. In conclusion, LUS helped monitor the different stages of controlled lung de-aeration during WLL and reduce the total amount of saline used. This technique will also reduce the risk of WLL-related complications.
摘要：
全肺灌洗（WLL）是肺泡蛋白沉积症的一线治疗方法。我们假设肺超声（LUS）将在15岁男孩的治疗过程中指导洪水。每个肺的WLL包括滴注盐水，然后进行运动疗法和液体引流。在第一次WLL中，肺反复被淹没，直到宏观检查清除了灌洗液。在这个过程中,LUS用于可视化肺通气。在第二次WLL中，我们使用LUS标志来指导灌洗量。液体支气管造影征象的出现表明，可以比第一次灌洗更早地停止盐水输注。总之,LUS有助于监测WLL期间受控肺脱气的不同阶段，并减少所用盐水的总量。该技术还将降低WLL相关并发症的风险。
