Avoinfuusio

Avoinfuusio is a Finnish term that translates to "open infusion" or "open transfusion." It refers to a medical procedure where a blood product or intravenous fluid is administered to a patient through an intravenous line that remains open, allowing for continuous or intermittent administration. This contrasts with procedures that might involve closing off the line between administrations or using a different method of delivery.

The term is often used in contexts where a consistent flow of fluids or medications is necessary. For example, in critical care settings, patients may have an avoinfuusio to maintain hydration, deliver medications like sedatives or vasopressors, or provide nutritional support. The "open" aspect signifies that the intravenous access point is readily available for use without needing to re-establish an IV line each time.

Key characteristics of an avoinfuusio include the use of an intravenous catheter, tubing, and a fluid or blood product bag. The rate of infusion is carefully controlled, either manually by adjusting a roller clamp on the tubing or automatically by using an infusion pump. Medical professionals monitor the patient and the infusion to ensure it is administered safely and effectively, adjusting the rate as needed based on the patient's condition and the goals of treatment. This method is fundamental in many areas of healthcare, from routine fluid replacement to complex life-saving interventions.
