What this trial studies

The SPEEDTAP-trial is a multicenter clinical trial that investigates two different methods for performing thoracentesis in emergency departments. Patients will be randomly assigned to receive either manual fluid removal in the emergency department or passive fluid drainage using gravity in the radiology department. The primary goal is to determine which method allows for quicker drainage of pleural effusions, with secondary outcomes including length of hospital stay and safety measures. A total of 188 patients will be included in this study across four emergency departments in Central Denmark.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have a clinically justified need for thoracentesis due to pleural effusion.

Not a fit: Patients experiencing life-threatening respiratory distress or those unable to provide consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to faster and more effective treatment for patients with pleural effusions, improving their overall outcomes.

How similar studies have performed: Other studies have explored thoracentesis methods, but this specific comparison of manual versus gravity drainage in emergency settings is novel.

* Clinically justified need for thoracentesis ( symptomatic relief and/or define the etiology of the effusion
* Without contraindication for thoracentesis in the emergency department (e.g., anticoagulant treatment)

Exclusion Criteria:

* Life-threatening respiratory distress
* Not able to give consent
* Previous pleurodesis
* Effusion does not appear free-flowing due to septations or loculations / suspected empyema
* Prior enrollment in the trial
* If randomization is not possible because decision to insert a pigtail catheter is made in the radiology department
