What is the difference between chest tube and chest drain?

Published in Medical Procedures 2 mins read

The terms chest tube and chest drain are often used interchangeably, but they actually refer to different aspects of the same medical procedure.

  • Chest tube is the actual physical tube inserted into the chest cavity. It's a flexible, hollow tube made of plastic or rubber.
  • Chest drain refers to the entire process of using a chest tube to remove air, fluid, or blood from the chest cavity.

Think of it like this: Chest tube is the tool, and chest drain is the job the tool does.

Here's a breakdown:

Chest tube:

  • Purpose: To drain fluid or air from the chest cavity.
  • Placement: Inserted through a small incision in the chest wall.
  • Types: Different types exist, including single-lumen, double-lumen, and pigtail catheters.

Chest drain:

  • Purpose: To relieve pressure in the chest cavity, allowing the lungs to expand properly.
  • Procedure: Involves inserting a chest tube, connecting it to a drainage system, and monitoring the drainage.
  • Indications: Used for conditions like pneumothorax (collapsed lung), hemothorax (blood in the chest cavity), and pleural effusion (fluid buildup in the chest cavity).

In essence, a chest tube is a vital part of the chest drain procedure. It's the physical conduit that allows for drainage, while chest drain encompasses the entire process of removing unwanted substances from the chest cavity.
