keskusveeniä

Keskusveeni refers to a central venous catheter, a medical device inserted into a large vein, typically in the neck, chest, or groin, to administer fluids, medications, or blood products, or to monitor central venous pressure. These catheters are often used for long-term treatments, such as chemotherapy, or for patients who require frequent access to the bloodstream. The insertion procedure is performed by trained medical professionals in a sterile environment to minimize the risk of infection.

There are several types of central venous catheters, including tunneled catheters, peripherally inserted central catheters (PICCs), and non-tunneled catheters. Tunneled catheters are placed under the skin and emerge from the chest, allowing for longer-term use. PICCs are inserted into a vein in the arm and threaded up to a large vein in the chest. Non-tunneled catheters are inserted directly into a large vein and are typically used for shorter durations.

The use of central venous catheters can be associated with certain risks and complications, such as infection, blood clots, and pneumothorax (collapsed lung). However, when used appropriately and with proper care, central venous catheters are a valuable tool in modern medicine, enabling effective treatment and monitoring for a wide range of medical conditions. Regular cleaning and maintenance of the catheter site are crucial to prevent complications.
