Infusionsbehandling

Infusionsbehandling, or intravenous infusion therapy, is a medical treatment in which liquids, medications, or nutrients are delivered directly into a vein through an infusion set. The method allows controlled, gradual administration over minutes or hours and is used in hospitals, clinics, and, with proper support, at home.

Venous access may involve a peripheral IV for short-term therapy or a central venous access device such as a catheter, a PICC line, or a port. Infusion pumps or gravity systems regulate the rate. Solutions are prepared under aseptic conditions to minimize contamination.

Common contents include isotonic saline or lactated Ringer's solutions, dextrose and electrolyte admixtures, or parenteral nutrition. Medications given by infusion include antibiotics, chemotherapy, monoclonal antibodies, analgesics, or vitamins. Blood products and hydration therapy are also common indications.

Before starting, clinicians assess patient identity, allergies, venous access, and drug compatibility. The prescribed rate, volume, and duration are supervised by nursing staff. Site care and aseptic technique reduce infection risk, while monitoring for infiltration, phlebitis, or adverse reactions is essential.

Risks include infection, thrombosis, infiltration, electrolyte disturbances, fluid overload, and catheter-related complications. Prevention relies on careful technique, regular site assessment, and patient education. In some settings, home infusion programs enable ongoing therapy with remote monitoring and nursing support.
