Keskuslaskimoviemäri

Keskuslaskimoviemäri, often abbreviated as CVC (Central Venous Catheter), is a medical device used to administer fluids, medications, blood products, and nutrition directly into a large vein, typically in the chest, neck, or groin. It is inserted under sterile conditions and is designed to remain in place for extended periods. The catheter's tip rests in the superior or inferior vena cava, the large veins that carry blood back to the heart. This central placement allows for rapid and efficient distribution of substances into the bloodstream, bypassing smaller peripheral veins.

The primary indications for a keskuslaskimoviemäri include the need for long-term intravenous therapy, such as chemotherapy, parenteral nutrition, or frequent blood transfusions. It is also essential for monitoring central venous pressure, which can provide valuable information about a patient's fluid status and cardiac function. Furthermore, CVCs are crucial in situations where peripheral veins are difficult to access, such as in patients with poor venous access or during emergency resuscitation.

While beneficial, keskuslaskimoviemäri also carries potential risks. The most common complications include infection at the insertion site or within the bloodstream, thrombosis (blood clot formation) around the catheter, and pneumothorax (collapsed lung) if inserted in the chest area. Proper insertion techniques, strict aseptic precautions, and regular catheter care are vital to minimize these risks. The duration of CVC use is determined by the patient's medical condition and is removed as soon as it is no longer medically necessary.
