They are widely used for intravenous administration of drugs, for infusion-transfusion therapy and for taking blood samples for analysis.
Catheterization of the central veins - the upper and lower vena cava through their tributaries is used not only for the introduction of drugs and blood sampling, but also for the implantation of a pacemaker, for probing the heart cavities, conducting X-ray contrast studies, for modern methods of blood purification (hemosorption, etc.).
Catheterization of the superior vena cava through the subclavian or jugular vein is the main way to measure central venous pressure.
Indications
- long operations with large blood loss;
- prolonged and intensive infusion therapy;
- inaccessibility of peripheral veins;
- the need to control changes in central venous pressure;
- parenteral nutrition, involving transfusions of hyperosmolar solutions;
- diagnostic and control studies;
- carrying out special therapeutic measures (hemosorption, etc.).
If necessary, it is possible to order catheters with a hydrophilic coating.
