OBJECTIVE: The effect of pulmonary complications of COVID-19, such as pneumothorax, pneumomediastinum, and subcutaneous emphysema, is still unclear. This study aimed at investigating the relationship between COVID-19 and spontaneous pneumothorax.

PATIENTS AND METHODS: This study was conducted as a single-center retrospective study. Groups were assigned as study and control groups. The study group (n=120) included patients who were followed up in ICU and developed pneumothorax during their follow-up. The control group (n=120) included patients who did not develop a pneumothorax in ICU and who had been randomly selected using hospital records. Demographic findings, laboratory parameters, radiological findings, clinical management, patients’ follow-up patterns, and survival status of the patients were recorded.

RESULTS: There was a significant relationship between gender, outcome, last hospitalization, general condition, first follow-up, intubation, uptake tomography, uptake rate, CO-RADS, and involvement variables between groups (p<0.05). In the survival analysis performed in the control and study groups, a significant difference was obtained between the averages of the two groups (LogRank=3.944, p<0.05). Intubation and mortality rates of the patients who developed pneumothorax during the patient follow-ups were significantly higher than the control group.

CONCLUSIONS: We found that patients diagnosed with COVID-19 who developed pneumothorax during intensive care follow-up had a higher hospital stay and intubation rate. The pneumothorax rate was also higher in follow-up methods such as noninvasive/HFO providing PEEP to the patients. The data in our study may help reducing mortality by shedding light on the early prevention and recognition of pneumothorax in critically ill patients diagnosed with COVID-19.
