Introduction. Iatrogenic pneumothoracis, barotraumas, and tracheoesophageal fistulae, especially after prolonged intubation, and tracheal stenosis are all entities involving thoracic surgeons’ consultation and management. With the surge of COVID-19 cases particularly in the critical care settings, various types of complications have been observed that require intervention from thoracic surgeons. Methods and Materials. A retrospective study was conducted in an academic healthcare institute in the Eastern Province of Saudi Arabia. We included all COVID-19 cases admitted to ICU in the period between March 15, 2020, and August 15, 2020, requiring thoracic surgery consultation and management. Non-COVID-19 critical cases and iatrogenic pneumothorax were excluded. Results. Of 122 patients who were admitted to ICU with COVID-19, 18 patients (14.75%) required thoracic surgery consultation and management. We discovered a significant association between the outcomes and reintubation rates and the rate of pneumothorax occurrence. The survival analysis showed improvement in patients who had thoracostomy tube insertion as a management than the group who were treated conservatively. On the other hand, there was a significant difference between the COVID ICU group who had thoracic complication and those who did not regarding the length of hospital stay. Conclusion. Noniatrogenic pneumothorax, subcutaneous emphysema, and mediastinal emphysema are well-known thoracic entities, but their presence in the context of COVID-19 disease is a harbinger for worse prognosis and outcomes. The presence of pneumothorax may be associated with better prognosis and outcome compared to surgical and mediastinal emphysema.
INTRODUCTION: Coronavirus illness 2019, commonly referred to as COVID-19, is a highly infectious disease brought on by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 was declared a universal pandemic in March 2020 by the World Health Organization and is a severe health issue with unprecedented morbidity and mortality rates. Both surgical and mediastinal emphysema have been seen in cases of critically ill COVID-19 patients in several hospitals in the Eastern Province of Saudi Arabia. METHODS: This was a retrospective, cross-sectional, multicentric study involving several hospitals in the Saudi Arabian Eastern Province. Data were collected from intensive care units (ICUs) in these hospitals from March 2 to August 2, 2020. The inclusion criteria consisted of all patients who tested positive for SARS-CoV-2 and were admitted to a critical care unit. RESULTS: Thirty patients required thoracic consultation and management, including 26 males (81.3%) and 4 females (12.5%) (1:0.15) who developed surgical and mediastinal emphysema requiring thoracic surgery intervention. Most of the patients were on high ventilation settings, and the mean duration of ventilator support was 16.50 ± 13.98 days. Two patients (6.3%) required reintubation. The median positive end-expiratory pressure (PEEP) was 12 ± 2.80 cmH 2 O with a median FiO2 of 70% ± 19.73. On average, thoracic complications occurred on day 3 (±6.29 days) postintubation. Ten patients (33.33%) experienced a pneumothorax associated with surgical emphysema (SE), 1 patient (3.33%) presented with only mediastinal emphysema; 17 patients (56.66%) with only SE, and 1 (3.33%) had mediastinal emphysema associated with SE. We noted a correlation between the duration of ventilator support, the length of ICU stay ( P < 0.001), and the total length of stay (LOS) in the hospital ( P < 0.001). Total length of hospital stay showed significant association with the onset of complications ( P = 0.045) and outcomes ( P = 0.006). A significant association between PEEP and the duration of ventilator support was also evident with a P value = 0.009 and the onset of complications ( P = 0.043). In addition, we found a significant association between the group with pneumothorax in combination with SE, and their outcomes, with a P = 0.002. CONCLUSION: Surgical and mediastinal emphysema in the critically ill patients are usually attributed to barotrauma and high ventilations settings. During COVID-19 pandemic, these entities were seen and the pathogenesis was revisited and some attributed its presence to the disease process and destruction on lung parenchyma. The associated with extended LOS and delayed recovery in addition to poor prognosis were seen. Their presen...
