IV Cannula - How is the IV Cannula Attached to the Patient

by Lars Medicare Lars Medicare Manufacturer, Exporter, Supplier, He

A cannula is generally believed to be the hollow needle, and more often a lengthy plastic tube that has been inserted into the vein of the patient using a needle. The tubing is attached through a tape on the patient arm, in order to prevent it from coming out when the patient moves, followed by a sterile dressing that is placed over the punctured place in the skin where the cannula is inserted and preventing bacteria that is generally believed to be existing on the skin.

There are two kinds of veins that can be used for placing the IV Cannula. The IV cannula can be inserted into the peripheral vein which is any vein and is not in the torso, or can have the Cannula being inserted into the larger more central vein of the chest. The peripheral line is the IV Cannula that is connected to the vein throughout the process. These are generally considered to be the veins that are usually inserted in the arms or hand of the patient, although the leg or say the foot of the patient can also be used. This is the most common type of the iv process.

The peripheral line again can be used only for a shorter period of time, usually for three days because if used for a longer period of time then the bacteria that is usually present on the skin can travel into the blood or the tissue surrounding the IV injection sites causing huge infection. So whenever a peripheral line is required for more than three days, then the standard procedures here is to move the injection site to a new location every three days in order to prevent infection.

A Central line is an IV that is generally attached to the vein of the chest. Usually throughout the process the cannula is inserted through the chest wall of the patient, and is also possible to insert the cannula through the peripheral vein and then moving the cannula slowly upward unless and until it is in the central vein. The central veins are generally considered to be larger than the peripheral veins, so whenever a central line is used and the cannula is inserted through the chest or the neck the tubing can then turn out to be wider followed by small multiple tubes, that can be inserted through the larger one delivering several medications at once that are generally not allowed to be mixed.

To Conclude

Remember a central line also passes through the vein that carries blood directly into the heart. So any medication that is given this way turns out to be distributed much more quickly throughout the body. Medicines that are particularly harsh or higher on concentration are also likely to irritate the peripheral veins followed by the central line. However it is the IV Cannula Manufacturer central line that is generally believed to cause more bleeding, followed by infections whose chances are much higher because the contents of the line go more directly into the heart allowing the bacteria to spread quickly throughout the body.
