Tension pneumomediastinum (TPM) is a rare but potentially fatal clinical entity. TPM leads to the leakage of air into the mediastinal cavity and increased pressure in thoracic vessels, respiratory tract, and the heart. Herein, this report presents a series of five cases of coronavirus disease-2019 (COVID-19) that caused acute respiratory distress syndrome (ARDS) and TPM. All patients were male who had severe ARDS with a secondary lung infection that required invasive ventilation and had moderate positive-end expiratory pressure. All patients required vasopressors to maintain hemodynamics, and two patients needed decompression with chest drains. One patient received extracorporeal membrane oxygenation therapy. Three patients had cardiac arrest, and two patients died; thus, the mortality rate was 40%. Patients with COVID-19 pneumonia with ARDS required invasive ventilation and prone positioning. Secondary lung infection can cause TPM, and TPM may cause cardiac arrest. Management should be prompt recognition and decompression with the insertion of drains, and conservative treatment is required in stable cases. Protocols for the management of pneumomediastinum and TPM may enable early detection, earlier management, and prevention of TPM.

INTRODUCTION: COVID-19 can occasionally complicate into spontaneous pneumothorax (SP) and/or spontaneous pneumomediastinum (SM). This study aims at exploring the occurrence of SP and or SM, risk factors, and outcomes in COVID-19 patients. MATERIALS AND METHODS: All patients with COVID-19, which complicated into SP and/or SM at Hamad Medical Corporation (the principal public healthcare provider in Qatar) from March to September 2020, were retrospectively enrolled. The clinical diagnosis was confirmed by CXR and CT. Between-group comparisons were performed by using Chi-square and t-test. Differences were considered statistically significant at P ≤ .05. RESULTS: A total of 1100 patients were admitted, and 43 patients developed SP, SP + SM, or SM. Most patients were males (42/97.9%), and the most common comorbidity was diabetes mellitus (13/30.2%). All patients had acute respiratory distress syndrome (ARDS), and most patients had low lung compliance at the time of developing SP or SM. Twenty-two of the patients developed SP (51.2%), 11 patients had both SP and SM (25.6%), and 10 patients had SM only (23.3%). There was no significant difference in the development of SP or SM and patients' gender or blood group or whether patients were on invasive or noninvasive ventilation or even the mortality (P > .05). Lung compliance was significantly (P < .05) lower in patients complicated with SP and or SM. Patients with SP required significantly higher (P < .001) chest drain insertion. CONCLUSION: Patients with severe COVID-19 pneumonia can complicate into SP and SM. These complications are more common in male diabetic patients. Patients with ARDS and having low lung compliance are at a higher risk of developing SP, SP + SM, or SM.
