Pleural Effusion
Conditions
Keywords
lung compliance, pleural effusion, esophageal pressure
Brief summary
The effects of pleural drainage on lung mechanics are unknown. Insertion of esophageal balloon will allow us to measure and assess pleural pressure, and thus assess any possible effects of pleural fluid drainage may have on lung mechanics.
Detailed description
Esophageal balloon will be inserted prior to pleural fluid drainage.

Eligibility
Inclusion criteria
* Mechanically ventilated patients with significant pleural fluid documented by CT scan or US.who are candidates for pleural fluid drainage.
Exclusion criteria
* Patients with any of the following were excluded from the study. Previous lung or chest wall surgery, previous esophageal surgery, known Achalasia or any other esophageal motility or spasm disorder, presence of chest thoracostomy tube, and any significant chest wall abnormality such as kyphoskoliosis.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| chest wall and lung compliance | 1 year | The use of esophageal balloon allows us to partition respiratory system into its components, namely, chest wall and lung compliance. These measurements have not been described so far in patients undergoing pleural fluid drainage. Thus, assessment of esophageal pressure which is a surrogate of pleural pressure will allow us an accurate measurement of the effect of pleural fluid drainage on chest wall and lung mechanics. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| oxygenation | 1 year | We suspect that pleural fluid drainage will be associated with improved chest wall and lung mechanics. If this will be the case, then we expect a concomitant improvement in oxygenation. |
