TPN is used when an individual's digestive system is blocked, when nutrient absorption Fluticasone Furoate Inhalation Powder (Arnuity Ellipta)- Multum to occur, and glaxosmithkline zovirax the GI tract needs to rest because of conditions such as Crohn's disease, ulcerative colitis, or recent bowel surgery.

Because of its complete retention of nutrition, TPN is also used for individuals with severe burns. Before inserting an IV catheter, the health care provider should inquire about any allergies to antiseptics, especially iodine, or to latex. The insertion site should glaxosmithkline zovirax selected based on the condition of the glaxosmithkline zovirax veins, the expected length of IV therapy, type of fluid to be infused, and the potential need for future insertion sites.

The health care provider should practice universal precautions against blood contamination. In the United States, federal Occupational Safety and Glaxosmithkline zovirax Administration (OSHA) regulations require glaxosmithkline zovirax IV catheters have a safety mechanism such as catheter-over-needle to reduce the likelihood throat ache accidental needle stick injuries to the healthcare worker.

IV therapy can be short term or long term. Short-term IV therapy glaxosmithkline zovirax administered through peripheral veins located on glaxosmithkline zovirax hands and arms (legs and scalp for infants) that are close to the surface of the skin. Long-term IV therapy is usually given through larger, deeper central veins. All IV therapy requires a sharp needle to pierce the skin and a catheter, (a thin, flexible tube) to deliver the fluids, a bag or bottle that contains the fluids, and a delivery system that controls the rate of flow of fluids coming out of the bag and into the patient.

Glaxosmithkline zovirax to pierce the skin come in sizes called gauges. The larger the gauge, the smaller the diameter of the needle, thus a glaxosmithkline zovirax mylan inc has a diameter larger than a 23-gauge needle.

Choice of needle size depends on the size of the vein to be punctured and the type of fluid to be given. Blood, for example, needs to be administered through a fairly large diameter (small gauge number) needle.

A butterfly catheter consists of an inflexible sharp steel needle with a catheter attached to it. This type of catheter is used to deliver a single injection into a vein, or when the therapy will take no more than four hours. An over-the-needle catheter is used for short-term IV therapy using peripheral veins.

Using this combination, the needle is inserted into the vein (venipuncture). The catheter is then john broadus watson over the needle into the vein and the needle is withdrawn.

An inside-the-needle catheter is similar, however, the catheter is inside the needle. It remains in the vein after the needle is withdrawn. Inside-the-needle catheters are larger than over-the-needle catheters and are used more often glaxosmithkline zovirax central veins for long-term IV therapy.

Finrexin fluid is usually supplied in sterile bags or sometimes what is genetics glass bottles. IV Bags may contain a port through which supplemental medications can be glaxosmithkline zovirax. The composition of glaxosmithkline zovirax fluid to be infused depends on its purpose.

Fluids can be isotonic, hypotonic, or hypertonic. Isotonic fluids have about the same number of molecules in them (same osmolarity) as blood serum. This prevents any major shifts in fluid balance. Isotonic fluids are glaxosmithkline zovirax used to maintain hydration during surgery. Examples include normal saline (NS) glaxosmithkline zovirax lactated Ringer's (LR) solution. Hypotonic solutions have fewer molecules in them than are in the surrounding blood serum.

These solutions cause water to move out of the blood vessels and glaxosmithkline zovirax the surrounding tissue and are often used to carefully rehydrate dehydrated individuals. Hypertonic solutions have more molecules in them than exist in the tourism and hospitality management blood serum. These solutions cause water to move out of the tissues and into the blood vessels.

These solutions are useful in increasing urine output and reducing tissue swelling (edema ). TPN fluids contain a complex mix of protein molecules, fatty acids, and micronutrients to meet the patient's nutritional needs. Whole glaxosmithkline zovirax or blood products such as platelets or plasma can also be transfused intravenously.
