Infusion Pumps: Fluid propulsion systems driven mechanically, electrically, or osmotically that are used to inject (or infuse) over time agents into a patient or experimental animal; used routinely in hospitals to maintain a patent intravenous line, to administer antineoplastic agents and other drugs in thromboembolism, heart disease, diabetes mellitus (Insulin infusion systems is also available), and other disorders.

Preparing and Administering Intermittent Intravenous Medications with an Infusion Pump

Primary intermittent intravenous (IV) infusions are delivered alone as volume-controlled infusions, while secondary infusions are delivered with another IV fluid, usually maintenance fluids. Intermittent infusions are delivered over a specific amount of time, which is dictated by the type of medication, such as IV antibiotics. High-volume IV medications, anywhere from 50- to 500-mL infusions, are typically delivered using an infusion pump as either primary or secondary infusions. Infusion pumps deliver IV fluids in a volume-controlled manner, keeping medication side effects to a minimum and helping to prevent nurse medication errors. Careful review of the medication compatibility with maintenance fluids using an approved medication drug guide, pharmacy recommendations in the Medication Administration Record (MAR), and physician orders must be assessed prior to delivering an IV medication. This review will determine if primary or secondary delivery is appropriate based on the risk for patient harm, such as for concentrated electrolyte preparations like potassium. Certain medical conditions that preclude oral fluid intake, specific medication preparations, or situations that require an inc

Initiating Maintenance IV Fluids

Hospitalized patients frequently require the administration of intravenous (IV) fluids to maintain their fluid and electrolyte balance. Certain medical conditions that preclude oral fluid intake may necessitate IV fluid administration, with or without electrolytes, to prevent hypovolemia, dehydration, and electrolyte imbalances. Pre-surgical and pre-procedure patients who require anesthesia are often required to be NPO (i.e., nil per os; Latin for "nothing by mouth") to prevent aspiration and to maintain hydration during the procedure. Post-surgical and post-procedure patients may also require IV fluid administration to increase intravascular volume following surgical blood loss. IV fluids can be delivered by different types of administrations sets: gravity flow infusion devices, which rely on gravitation force to push the fluid to the patient's bloodstream, or infusion pumps, which use a pump mechanism that generates positive pressure. While administering maintenance IV fluids using an infusion pump is the most common approach, facility policy; availability of infusion pump equipment; and other limitations, such as a power outage, may necessitate the use of IV gravity tub

Preparing and Administering Secondary Intermittent Intravenous Medications

JoVE 10288

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT

Secondary intravenous (IV) infusions are a way to administer smaller volume-controlled amounts of IV solution (25-250 mL). Secondary IV infusions are delivered over longer periods of time than IV push medications, which reduces the risks associated with rapid infusions, such as phlebitis and infiltration. In addition, some antibiotic medications are only stable for a limited time in solution. The secondary IV medication tubing is connected to the primary macrobore (large internal diameter) IV tubing and is therefore "secondary" to the primary infusion. The secondary solution bag is typically hung higher than the primary infusion bag and is subsequently "piggybacked" on top of the primary IV infusion. This higher position places greater gravitational pressure on the secondary IV solution. As a result, the primary infusion is temporarily paused until the secondary infusion volume has been delivered. This approach ensures that the medication is completely infused due to an immediate return of maintenance IV infusion in the IV line. The secondary IV infusion can be safely delivered when the patient's fluid volume status permits temporarily pausing the delivery of maintenance fluid and in hype
