Abstract
PDF - Background
Pneumothorax (PTX) can occur as a complication of positive pressure ventilation in mechanically ventilated patients.
Methods
We retrospectively reviewed the clinical characteristics of patients who developed PTX during mechanical ventilation (MV) in the intensive care unit (ICU).
Results
Of the 326 patients admitted (208 men and 118 women; mean age, 65.3 ± 8.74 years), 15 (4.7%) developed PTX, which was MV-associated in 11 (3.3%) cases (6 men and 5 women; mean age, 68.3 ± 9.12 years) and procedure-associated in 4. Among the patients with MV-associated PTX, the underlying lung diseases were acute respiratory distress syndrome in 7 patients, interstitial lung disease in 2 patients, and chronic obstructive pulmonary disease in 2 patients. PTX diagnosis was achieved by chest radiography alone in 9 patients and chest computed tomography alone in 2 patients. Nine patients were using assist-control mode MV with the mean applied positive end-expiratory pressure, 9 ± 4.6 cmH2O and the mean tidal volume, 361 ± 63.7 ml at the diagnosis of PTX. Two patients died as a result of MV-associated PTX and their systolic pressure was below 80 mmHg and heart rates were less than 80/min. Ten patients were treated by chest tube insertion, and 1 patient was treated by percutaneous pigtail catheter insertion.
Conclusions
PTX can develop in patients undergoing MV, and may cause death. Early recognition and treatment are necessary to prevent hemodynamic compromise in patients who develop PTX.

- BACKGROUND
Acute respiratory failure can occur paradoxically on initiation of anti-tuberculosis (TB) treatment in patients with pulmonary TB. This study is aimed to analyze the clinical features of anti-TB treatment induced acute respiratory failure.
METHODS
We reviewed the clinical and radiological characteristics of 8 patients with pulmonary tuberculosis (5 men and 3 women; mean age, 55 +/- 15.5 years) who developed acute respiratory failure following initiation of anti-TB medication and thus required mechanical ventilation (MV) in the intensive care unit (ICU).
RESULTS
The interval between initiation of anti-TB medication and development of MV-requiring acute respiratory failure was 2-14 days (mean, 4.4 +/- 4.39 days), and the duration of MV was 1-18 days (mean, 7.1 +/- 7.03 days). At admission, body temperature and serum levels of lactate dehydrogenase and C-reactive protein were increased. Serum levels of protein, albumin and creatinine were 5.8 +/- 0.98, 2.3 +/- 0.5 and 1.8 +/- 2.58 mg/ml, respectively. Radiographs characterized both lung involvements in all patients. Consolidation with the associated nodule was noted in 7 patients, ground glass opacity in 2, and cavitary lesion in 4. Micronodular lesion in the lungs, suggesting miliary tuberculosis lesion, was noted in 1 patient. At ICU admissions, the ranges of the APACHE II and SOFA scores were 17-38 (mean, 28.2 +/- 7.26) and 6-14 (mean, 10.1 +/- 2.74). The mean lung injury score was 2.8 +/- 0.5. Overall, 6 patients died owing to septic shock and multiorgan failure.
CONCLUSIONS
On initiation of treatment for pulmonary TB, acute respiratory failure can paradoxically occur in patients with extensive lung parenchymal involvement and high mortality.
