Infuusiomuodot

Infuusiomuodot are the various methods by which an intravenous infusion is administered to a patient to deliver water‑soluble medications, nutrients or fluids. The technique is central to clinical practice in hospitals, outpatient clinics and emergency situations. Infusions are generally controlled by a pump, a gravity bag or a manual syringe, and the mode selected depends on the drug’s intended effect, the patient’s condition and the required precision of delivery.

Gravity infusion is the simplest mode, using a hanging bag of fluid that falls under the influence of gravity. It is inexpensive but gives only a rough rate that can vary with patient position. Manual syringe infusion allows a clinician to adjust the flow by hand and is useful when the patient is in a position that limits the use of pumps.

Programmable infusion pumps deliver drugs at a set infusion rate measured in milliliters per hour. Modern pumps can maintain a constant rate for hours or days, guard against occlusion and provide alarms for interruptions or disconnections. Power‑driven pumps also enable complex regimens such as bolus doses followed by maintenance infusion.

Bolus infusion delivers a fixed volume rapidly, used for analgesics or antibiotics when a quick concentration is needed. Continuous infusion maintains a stable drug level over time and is preferred for substances with narrow therapeutic windows. Fractionated infusion divides a dose into several smaller administrations spaced over the same period.

Infusion rate is calculated from the prescribed dose, concentration and desired duration. Safety protocols include checking the IV site, verifying drug compatibility, monitoring for phlebitis, and flushes to prevent occlusion. Adherence to aseptic technique prevents catheter‑related bloodstream infections.

Overall, infuusiomuodot provide flexible, safe delivery of intravenous therapy and are integral to patient care across a spectrum of medical specialties.
