The patients in the limited-ventilation and control groups were exposed to different mean (±SD) tidal volumes (7.2☐.8 vs. ResultsĪ total of 120 patients with similar clinical features underwent randomization (60 in each group). All other ventilatory variables were similar in the two groups. Within 24 hours of intubation, patients at high risk for the acute respiratory distress syndrome were randomly assigned to either pressure- and volume-limited ventilation (limited-ventilation group), with the peak inspiratory pressure maintained at 30 cm of water or less and the tidal volume at 8 ml per kilogram of body weight or less, or to conventional ventilation (control group), with the peak inspiratory pressure allowed to rise as high as 50 cm of water and the tidal volume at 10 to 15 ml per kilogram. However, the efficacy of this approach has not been established. The goal is to reduce lung injury due to overdistention. The most trusted, influential source of new medical knowledge and clinical best practices in the world.Ī strategy of mechanical ventilation that limits airway pressure and tidal volume while permitting hypercapnia has been recommended for patients with the acute respiratory distress syndrome.

Heterogenous inflammation may be a key finding in its mechanism. Pathological examination revealed a subpleural hematoma and pulmonary cyst with heterogenous lung inflammation.īarotrauma was a poor prognostic factor for coronavirus disease 2019, especially in the late phase. Contrastingly, in the 14-, 21-, and 28-day landmark analyses, the barotrauma group's survival rates were significantly worse (14-day: 41.7% vs. In the 7-day landmark analysis, there was no significant difference (75.0% vs. The barotrauma group's 90-day survival rate was significantly worse (47.7% vs. Barotrauma developed in 44 patients (22.9%). Additionally, we evaluated surgically treated cases of coronavirus disease 2019-related pneumothorax. Barotrauma within seven days before the landmark was defined as the exposure. We compared the 90-day survival between the barotrauma and non-barotrauma groups and performed landmark analyses on days 7, 14, 21, and 28. We retrospectively reviewed intubated patients with coronavirus disease 2019 from March 2020 to May 2021. To investigate the time-dependent characteristics and the etiology of coronavirus disease 2019-related-barotrauma.
Previous studies have reported barotrauma to be a mortality-risk factor however, its time-dependent nature and pathophysiology are not elucidated.
