Abstract:
Objective:To summarize the treatment experience of patients with different degree of acute respiratory distress syndrome (ARDS) caused by inhalation of white smoke from burning smoke bomb.
Methods:A batch of 13 patients with different degree of ARDS caused by inhalation of white smoke from burning smoke bomb, including 2 patients complicated by pulmonary fibrosis at the late stage, were admitted to our unit in February 2016. Patients were divided into mild (9 cases), moderate (2 cases), and serious (2 cases) degree according to the ARDS Berlin diagnostic criteria. Patients with mild and moderate ARDS were conventionally treated with glucocorticoid. Patients with severe ARDS were sequentially treated with glucocorticoid and pirfenidone, and ventilator-assisted breathing, etc. were applied. The vital signs, arterial oxygenation index, changes of lung imaging, pulmonary ventilation function, general condition, and the other important organs/systems function were timely monitored according to the condition of patients. The above indexes were also monitored during the follow-up time of 10-15 months post injury. Data were processed with SPSS 18.0 statistical software.
Results:(1) The symptoms of respiratory system of patients with mild and moderate ARDS almost disappeared after 3 days′ treatment. Their arterial oxygenation index was decreased from post injury day 1 to 4, which almost recovered on post injury day 7 and completely recovered one month post injury. The symptoms of respiratory system of patients with severe ARDS almost disappeared at tranquillization condition 1-3 month (s) post injury. Their arterial oxygenation index was decreased from post injury day 3 to 21, which gradually recovered 1-3 month (s) post injury and was normal 15 months post injury. (2) Within 24 hours post injury, there was no obvious abnormality or only a little texture enlargement of lung in image of chest CT or X-rays of patients with mild and moderate ARDS. One patient with moderate ARDS had diffuse patchy and ground-glass like increased density shadow (pulmonary exudation for short) at post injury hour 96. Chest iconography of all patients with mild and moderate ARDS showed no abnormalities 10 months post injury. Both lungs of each of the two patients with severe ARDS showed obvious pulmonary exudation at post injury hours 45 and 75, respectively. One patient with severe ARDS showed no abnormality in chest image 10 months post injury, but there was still a small mesh-like increased density shadow in double lobes with slight adhesion of pleura in the other patient with severe ARDS 15 months post injury. (3) All patients showed severe restrictive hypoventilation when admitted to hospital. Pulmonary ventilation function of patients with mild and moderate ARDS recovered to normal one month post injury, and they could do exercises like running, etc. Pulmonary ventilation function of one patient with severe ARDS recovered to normal 6 months post injury, and the patient could do exercises like running, etc. The other patient with severe ARDS showed mild restrictive hypoventilation 15 months post injury and could do exercises like rapid walking, etc. (4) The condition of all mild and one moderate ARDS patients was better on post injury day 3, and they were transferred to the local hospital for subsequent treatment and left hospital on post injury day 21. One patient with moderate ARDS healed and left hospital on post injury day 29. Patients with severe ARDS healed and left hospital on post injury day 81. During the follow-up time of 10-15 months post injury, the other important organs/systems of all patients showed no abnormality, and there was no adverse reaction of glucocorticoid like osteoporosis, femoral head necrosis, or metabolic disorder. Two patients with severe ARDS did not have any adverse reaction of pirfenidone like liver function damage, photosensitivity, anorexia, or lethargy.
Conclusions:Early enough and uninterrupted application of glucocorticoid can significantly reduce the ARDS of patients caused by inhalation of white smoke from burning smoke bomb. Sequential application of glucocorticoid and pirfenidone can effectively treat pulmonary fibrosis at the late stage.
