Infusion therapy
|
is the delivery of medications in solution and fluids by parenteral (piercing of skin or mucous membranes) route through a wide variety of catheter types and locations using multiple procedures.
|
|
isotonic
hypertonic hypotonic |
Parenteral solutions within that normal range are ____________,
those fluids greater than 300 mOsm/L are ____________ and those fluids less than 270 mOsm/L are. _________ |
|
Phlebitis
|
is the inflammation of a vein caused by mechanical, chemical, or bacterial irritation
|
|
Infiltration
|
occurs when IV solution leaks into the tissues around the vein.
|
|
Midline catheters
|
can be anywhere from 3 to 8 inches long, 3 to 5 Fr, and double or single lumen. They are inserted through the veins of the upper arm. The median antecubital vein is used most often if insertion is done without the aid of ultrasound guidance. With ultrasound guidance, deeper veins can be accessed and the insertion site can be further above the antecubital fossa. The basilic vein is preferred over the cephalic vein because of its larger diameter and straighter path
|
|
vesicant medications
|
—drugs that cause severe tissue damage if they escape into the subcutaneous tissue (extravasation)
|
|
In central IV therapy
|
, the vascular access device (VAD) is placed in the central circulation, specifically within the superior vena cava (SVC) near its junction with the right atrium.
|
|
peripherally inserted central catheter (PICC)
|
A is a long catheter inserted through a vein of the antecubital fossa (inner aspect of the bend of the arm) or the middle of the upper arm. Nurses who insert these CVADs require special training and certification.
|
|
Nontunneled percutaneous central venous catheters (CVCs)
|
are inserted by a physician through the subclavian vein in the upper chest or the internal jugular veins in the neck using sterile technique.
|
|
Tunneled central venous catheters (VADs)
|
that have a portion of the catheter lying in a sub- cutaneous tunnel, separating the points where the catheter enters the vein from where it exits the skin.
|
|
Implanted ports
|
are very different from other central vascular access devices (CVADs). They consist of a portal body, a dense septum over a reservoir, and a catheter. They can be single- or double-lumen and come in various sizes. A subcutaneous pocket is surgically created to house the port body. The catheter is inserted into the vein and attached to the portal body.
|
|
turbidity
|
(cloudiness)
|
|
primary continuous administration set
|
A is used to infuse the primary IV fluid by either a gravity infusion or an electronic infusion pump.
|
|
short secondary administration set, also known as a piggyback set,
|
A ? is attached to the primary set at a Y–injection site and is used to deliver intermittent medications.
|
|
Intermittent administration-
|
• If a secondary administration set is detached from the primary set, it should be considered an intermittent set and changed every 24 hours
• When the administration set is used for infusion of lipid solutions, change it every 24 hours. • Change blood tubing within 4 hours • tubing used to infuse propofol (Diprivan) every 6 to 12 hourr • These fluids are thick and can clog the tubing. |
|
Syringe pumps
|
use an electronic or battery-powered piston to push the plunger continuously at a selected milliliter-per-hour rate. The use of syringe pumps is limited to small-volume continuous or intermittent infusions and depends on the syringe size.
|
|
Ambulatory pumps
|
are generally used for home care patients and allow them to return to their usual activities while receiving infusion therapy. These pumps have a wide range of sizes, with some requiring a backpack, but they usually weigh less than 6 pounds.
|
|
smart pumps
|
(infusion pumps with dosage calculation software) have been promoted to reduce adverse drug events (ADEs).
|
|
Subcutaneous therapy
|
may be used in palliative care patients who cannot tolerate oral medications, when IM injections are too painful, or when vascular access is not available or is too difficult to obtain. Most often, this type of infusion is used in hospices for pain management.
|
|
Hypodermoclysis
|
involves the slow infusion of isotonic fluids into the patient's subcutaneous tissue.
|
|
Intraosseous (IO) therapy
|
allows access to the rich vascular network in the red marrow of bones. Although IO has previously been regarded as a pediatric procedure, it is now considered acceptable for use in adults. Victims of trauma, burns, cardiac arrest, diabetic ketoacidosis, and other life-threatening conditions benefit from this therapy because often clinicians cannot access these patients’ vascular systems for traditional IV therapy
|
|
Intraperitoneal (IP) therapy
|
is the administration of chemotherapy agents into the peritoneal cavity. IP therapy is used to treat intra-abdominal malignancies such as ovarian and gastrointestinal tumors that have moved into the peritoneum after surgery
|
|
epidural space
|
-between the dura mater and vertebrae The epidural space consists of fat, connective tissue, and blood vessels that protect the spinal cord. Medications infused into the epidural space must diffuse through the dura mater, and there is the possibility that some drug will be absorbed systemically.
|
|
subarachnoid space
|
. space between the arachnoid mater and pia mater
|
|
Intrathecal medications
|
are infused into the subarachnoid space closer to the spinal cord, allowing reduced doses.
