Modified thoracentesis technique using a triple-lumen catheter.

Area of Science:

• Pulmonology
• Medical Procedures
• Interventional Techniques

Background:

• Symptomatic pleural effusions often require therapeutic thoracentesis.
• Traditional bedside thoracentesis carries risks such as lung injury and incomplete drainage, exacerbated by inexperienced practitioners and kit limitations.
• Tube thoracostomy is an alternative but may not be ideal for all cases.

Purpose of the Study:

• To present a modified bedside thoracentesis technique using a triple-lumen catheter and guidewire.
• To address the limitations and risks associated with standard thoracentesis kits and inexperienced operators.
• To improve patient comfort, minimize iatrogenic injury, and enhance pleural fluid drainage efficacy.

Main Methods:

• A modified Seldinger technique involving the pleural space was employed.
• A triple-lumen catheter was inserted over a guidewire into the pleural space.
• The procedure focused on overcoming the shortcomings of conventional packaged thoracentesis kits.

Main Results:

• The modified technique demonstrated improved patient comfort.
• It significantly minimized the risk of parenchymal lung injury and abdominal organ injury.
• More complete drainage of the pleural cavity was achieved compared to standard methods.
• The approach leverages existing resident skills in central line placement, potentially improving comfort and proficiency.

Conclusions:

• The modified triple-lumen catheter approach offers a safer and more effective alternative for therapeutic thoracentesis in select patients.
• This technique mitigates risks associated with standard bedside procedures and enhances procedural success.
• Further adoption may improve resident training and patient care for pleural effusions.
