Air introduction during pleural effusion drainage for trapped lung
Official title: Air Entrainment vs. Standard Treatment in Non-Expandable Lung With Persistent Pleural Effusion: A Randomised Controlled Double-Blind Trial
Run by Cambridge University Hospitals NHS Foundation Trust · NCT06959719 · Data updated 2026-11-12
This study is testing if adding air during the drainage of fluid from the chest can help adults with a trapped lung feel less pain and have a better experience compared to the usual method.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with a confirmed diagnosis of non-expandable lung and persistent pleural effusion scheduled for drainage.
✕Probably not a fit
Patients with a history of pleurodesis, active infections, or those requiring indwelling pleural catheters may not benefit from this study.

What this trial studies
This randomized controlled trial evaluates the effectiveness of controlled air introduction into the pleural space during drainage of pleural effusions in patients with non-expandable lung (NEL). The study aims to determine if this air entrainment technique can reduce pain, improve patient satisfaction, and enhance fluid drainage compared to standard treatment. Participants will be randomly assigned to either the air entrainment group or the control group, with assessments made on pain relief, fluid volume drained, and overall patient experience. The trial is conducted at Cambridge University Hospital and includes adults scheduled for pleural effusion drainage.
Why it matters
Potential benefit: If successful, this approach could significantly reduce pain and improve the overall experience for patients undergoing pleural effusion drainage.
How similar studies have gone: While this specific approach is novel, preliminary evaluations suggest that air entrainment may provide better pain relief than traditional methods.
