Objective: To analyze the clinical characteristics and prognosis of coronavirus disease 2019 (COVID-19) patients complicated with pneumothorax., Methods: The clinical data of 7 COVID-19 patients complicated with pneumothorax admitted to Huanggang Central Hospital from January 3 to March 10, 2020 were retrospectively analyzed. The clinical features, diagnosis and treatment were summarized, and experience in the treatment of COVID-19 was shared., Results: (1) General information: among the 7 patients, 5 were males and 2 were females. Four of them had no underlying disease, and 1 had a history of diabetes and hypertension. One patient had only a history of hypertension. There were 6 cases of right pneumothorax and 1 case of bilateral pneumothorax. The 7 patients had a long hospital stay, all over 4 weeks, mostly complicated with multiple organ dysfunction. (2) Imaging examination: 1 case evolved from the early stage to the advanced stage within 1 week and to the severe stage within 2 weeks. Pneumothorax occurred 4 weeks later, and was absorbed within 2 weeks. The remaining 6 patients presented progressive stage on admission, all of them advanced to severe stage within 1 to 2 weeks, and most of them presented diffused consolidation shadows, striation shadows and fibrosis of both lungs, obvious pleural adhesion, and extremely slow lesion absorption. (3) Treatment: 1 severe patient with pneumothorax 4 weeks after onset was given non-invasive mechanical ventilation. The remaining 6 critically ill patients were treated with endotracheal intubation and mechanical ventilation. Five patients were treated with mechanical ventilation within 3 days after the occurrence of pneumothorax, and 1 patient was treated with mechanical ventilation after 11 days. (4) Outcome: 1 patient without endotracheal intubation was continuously given nasal high-flow oxygen therapy, and the condition was stable. Four of the 6 patients complicated with pneumothorax after endotracheal intubation died, and the other 2 patients successfully removed the drainage tube within 2 weeks of closed thoracic drainage, and their condition gradually stabilized., Conclusions: COVID-19 complicated with pneumothorax is a dangerous disease with poor prognosis, and should be paid adequate attention.
