Efficacy assessment of the drainage with permanent airflow measurement in the treatment of pneumothorax with air leak

Thorac Cardiovasc Surg. 2014 Sep;62(6):509-15. doi: 10.1055/s-0033-1359714. Epub 2013 Dec 2.


Aim: The aim of this study was to compare the efficacy of the treatment of patients with spontaneous pneumothorax with air leak (AL) using two different chest drainage systems.

Methods: Patients were randomized into two groups: group A included 30 patients (23 males and 7 females, mean age 41.1 ± 16.29 y, range 17-71 y) in which digital drainage system was used, group B with 30 patients (22 males and 8 females, mean age 40.3 ± 15.74 y, range 18-72 y) in which traditional suction drainage system was applied.The following variables were evaluated: intensity of AL, duration of the chest tube drainage, delay in surgery, length of stay, and the overall hospitalization costs.

Results: In group A the mean drainage duration was 47.63 hours, the hospitalization time was about 5.10 days, and the cost of hospitalization was €1,495. In group B the mean drainage duration was 84.93 hours, the hospitalization time was 6.97 days, and the hospitalization cost was €1,925.

Conclusion: The digital drainage system applied in the treatment of AL in patients with pneumothoraces reduced the duration of the drainage, the length of hospital stay, and overall hospitalization costs.
