Controlled access
Ultrasound navigation has turned a “blind” puncture into a precise manipulation: the vein is visualized in real time, which minimizes complications (pneumothorax, arterial puncture). The tip of the catheter is positioned at the cavoatrial junction - optimal for infusion rate and vein preservation. Multiway catheters allow the simultaneous administration of incompatible drugs. Care: aseptic dressings, rinsing after use; If you need multi-month access, consider a port system (next Options page).
Indications
- chemotherapy - multi-month courses with preservation of veins;
- long-term infusion therapy, parenteral nutrition, frequent blood sampling;
- “bad” peripheral veins, phlebitis from drugs;
- the need for multiple contrast studies.
Catheter or port
CVC - quick access for the hospital stage (week); port system - a reservoir with a membrane implanted under the skin for many months of outpatient treatment: invisible, does not interfere with showering and swimming, can be punctured with a special needle in seconds, and lasts for years. For chemotherapy, the port is the standard of care for the patient: the veins of the arms are preserved, irritating drugs enter the central bloodstream safely, and the risk of extravasation is minimal. Outpatient installation under ultrasound/X-ray control.
