INTRODUCTION: There are various reports of air leaks with coronavirus disease 2019 (COVID-19). We undertook a systematic review of all published case reports and series to analyse the types of air leaks in COVID-19 and their outcomes.
METHODS: The literature search from PubMed, Science Direct, and Google Scholar databases was performed from the start of the pandemic till 31 March 2021. The inclusion criteria were case reports or series on (1) laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, (2) with the individual patient details, and (3) reported diagnosis of one or more air leak syndrome (pneumothorax, subcutaneous emphysema, pneumomediastinum, pneumoperitoneum, pneumopericardium).
RESULTS: A total of 105 studies with 188 patients were included in the final analysis. The median age was 56.02 (SD 15.53) years, 80% males, 11% had previous respiratory disease, and 8% were smokers. Severe or critical COVID-19 was present in 50.6% of the patients. Pneumothorax (68%) was the most common type of air leak. Most patients (56.7%) required intervention with lower mortality (29.1% vs. 44.1%, p = 0.07) and intercostal drain (95.9%) was the preferred interventional management. More than half of the patients developed air leak on spontaneous breathing. The mortality was significantly higher in patients who developed air leak with positive pressure ventilation (49%, p < 0.001) and required escalation of respiratory support (39%, p = 0.006).
CONCLUSION: Air leak in COVID-19 can occur spontaneously without positive pressure ventilation, higher transpulmonary pressures, and other risk factors like previous respiratory disease or smoking. The mortality is significantly higher if associated with positive pressure ventilation and escalation of respiratory support.
