NCT06340178

Brief Summary

The purpose of this randomized controlled study is to evaluate the extent to which injection of a small amount of fluid in the pleural cavity at the biopsy site may reduce the risk of pneumothoraces, in addition to patient positioning to allow biopsy in gravity-dependent areas of the lung.

Outcome Measures

Primary Outcomes (1)

  • Number of patients with pneumothorax

    Reduction of pneumothorax occurrence in patients with biopsy in dependent lung areas and pleural fluid administration compared to patients with biopsy in dependent lung areas without fluid administration. Immediately after the lung biopsy, the final CT scan of the intervention is used to check whether a pneumothorax is present or not - i.e. whether there is new air in the pleural cavity.

    Immediate after biopsy, expected to be on average 5 minutes

Secondary Outcomes (3)

  • Number of patients with bleeding

    Immediate after biopsy, expected to be on average 5 minutes

  • Number of patients with chest tube placement

    Immediate after biopsy, expected to be on average 5 minutes

  • Number of patients with air embolism

    Immediate after biopsy, expected to be on average 5 minutes

Study Arms (2)

Fluid administration

EXPERIMENTAL

Fluid is given in pleural or subpleural space during CT-guided lung biopsy.

Procedure: Fluid application during ct-guided lung biopsy

No fluid administration

NO INTERVENTION

No additional fluid is given prior to the CT-guided lung biopsy.

Interventions

Injection of a small amount of fluid (max. 20 ml sodium chlorid) in the pleural cavity at the biopsy site

Fluid administration
