Dränagekathetern

Dränagekatheter, often referred to as drains, are medical devices used to remove pus, blood, serum, or other fluids from a body cavity, organ, or wound. They are typically inserted during or after surgery, or to treat an infection or accumulation of fluid. The primary purpose of a drain is to prevent the buildup of fluid that could impede healing, cause pain, or lead to further complications such as infection.

There are various types of drainage catheters, differing in their material, design, and method of suction. Some common types include Penrose drains, which are open, soft rubber tubes that allow fluid to passively drain onto a dressing. Jackson-Pratt drains and Hemovac systems are closed suction drains, utilizing a negative pressure bulb or reservoir to actively draw fluid away from the surgical site. Silicone or latex are frequently used materials.

The insertion of a drainage catheter is a sterile procedure performed by a qualified healthcare professional. The drain is typically sutured in place to prevent accidental dislodgement. The external end of the drain is usually connected to a collection bag or dressing. The amount and type of fluid drained are monitored to assess the patient's recovery and identify any potential problems. Drains are usually removed once the drainage output decreases significantly and the surgeon deems it no longer necessary. Complications, though uncommon, can include infection at the insertion site, pain, or premature dislodgement.
