OBJECTIVES Our goal was to evaluate the prevalence of and risk factors for pneumothorax in patients with invasive mechanical ventilation in the intensive care unit (ICU) diagnosed with coronavirus disease 2019 pneumonia. METHODS The prevalence of pneumothorax was retrospectively reviewed in 107 patients diagnosed with coronavirus disease 2019 pneumonia and treated in an ICU in Turkey between 11 March 2020 and 30 April 2020. RESULTS The patients were aged 19–92 years; 37 (34.6%) were women. Pneumothorax developed in 8 (7.5%) of the intubated patients. Four (50%) of the patients with pneumothorax and 68 (68.7%) of those without it died. In the univariable logistic regression analysis of the presence of comorbid diseases (P = 0.91), positive end-expiratory pressure (P = 0.18), compliance (P = 0.93), peak pressure (P = 0.41) and the Horowitz index (P = 0.13) did not show statistically significant effects in increasing the risk of pneumothorax. CONCLUSIONS There was no significant increase or decrease in the risk of pneumothorax in patients treated with invasive mechanical ventilation after the diagnosis of coronavirus disease 2019-related pneumonia/acute respiratory distress syndrome. However, consideration of the risk of pneumothorax in these individuals may have the potential to improve the prognoses in such settings.

In the treatment of malignant pleural effusion, patients with daily drainage of less than 200 ml before TS developed less recurrence than patients with daily drainage of more than 200 ml. Longer time period between the diagnosis of MPE and onset of CTD increased recurrence.

OBJECTIVES The incidence of pneumomediastinum (PNMD), its causes of development and its effect on prognosis in the coronavirus disease 2019 (COVID-19) are not clear. METHODS Between March 2020 and December 2020, 427 patients with real-time reverse transcriptase-polymerase chain reaction-confirmed COVID-19 admitted to the intensive care unit were analysed retrospectively. Using receiver operating characteristic analysis, the area under the curve (AUC) for initial invasive mechanical ventilation (MV) variables such as initial peak inspiratory pressure (PIP), PaO2/FiO2 (P/F ratio), tidal volume, compliance and positive end-expiratory pressure was evaluated regarding PNMD development. RESULTS The incidence of PNMD was 5.6% (n = 24). PNMD development rate was 2.7% in non-invasive MV and 6.2% in MV [odds ratio (OR) 2.352, 95% confidence interval (CI) 0.541–10.232; P = 0.400]. In the multivariate analysis, the independent risk factors affecting the development of PNMD were PIP (OR 1.238, 95% CI 1.091–1.378; P < 0.001) and P/F ratio (OR 0.982, 95% CI 0.971–0.994; P = 0.004). P/F ratio (AUC 0.815, 95% CI 0.771–0.854), PIP (AUC 0.780, 95% CI 0.734–0.822), compliance (AUC 0.735, 95% CI 0.677–0.774) and positive end-expiratory pressure (AUC 0.718, 95% CI 0.668–0.764) were the best predictors for PNMD development. Regarding the multivariate analysis, independent risk factors affecting mortality were detected as age (OR 1.015, 95% CI 0.999–1.031; P = 0.04), comorbidity (OR 1.940, 95% CI 1.100–3.419; P = 0.02), mode of breathing (OR 48.345, 95% CI 14.666–159.360; P < 0.001), PNMD (OR 5.234, 95% CI 1.379–19.857; P = 0.01), positive end-expiratory pressure (OR 1.305, 95% CI 1.062–1.603; P = 0.01) and tidal volume (OR 0.995, 95% CI 0.992–0.998; P = 0.004). CONCLUSIONS PNMD development was associated with the initial P/F ratio and PIP. Therefore, it was considered to be related to both the patient and barotrauma. PNMD is a poor prognostic factor for COVID-19.

Objectives: In this study, the effect of multi-trauma on treatment results in flail chest patients who underwent chest wall stabilization was investigated. Methods: The data of thirty-six flail chest cases between the ages of 18–79 who were consulted for thoracic surgery were retrospectively analyzed in the study. The presence of flail chest in the patients was confirmed by thoracic surgeons, and the multi-traumas were confirmed through the diagnoses made by specialist physicians reexamining clinical methods. Results: It was found that 27 (75%) of flail chest cases evaluated had multi-trauma, and 3 (8.3%) of the cases had mortality in the study. It was found that the duration of the intensive care unit stay and the number of days on invasive mechanical ventilation of the cases were positively correlated with the number of surgical areas exposed to trauma (p<0.05). According to the univariate binary logistic regression analysis, it was found that the total number of rib fractures (OR = 1.44, p=0.055), the number of fixed ribs (OR = 0.76, p=0.558), the number of plates placed for fixation (OR = 0.70, p=0.368), and the number of additional trauma areas outside the thorax (OR = 6.76, p=0.076) were not statistically significant in increasing the mortality risk. Conclusion: Considering that multi-trauma is an effective factor in the prolongation of the duration of treatment, the management of traumas with different specialties can positively affect the treatment results and reduce the risk of mortality.
