What is an intravenous needle?
intravenous needle is a type of needle that is inserted into a vein for administering drugs and fluids as arranged by a doctor. These types of needles are usually a small, hollow tube called a cannula, which is messed up through a sharp needle called trochar. The needle is used to pierce the skin and access to the vein. Once the vein is inside, the trochar is inserted and leaves the plastic cannula at a place for drug administration.
The intravenous needle is supplied in different diameter sizes called the meter. The smaller the meter, the larger the needle diameter. The 16 needle of 16 is larger than the 24 -length needle. The type of intravenous (IV) therapy that is arranged can determine the size of the IV catheter. For example, blood transfusion requires a 18 or 20 needle.
Inserting an intravenous needle should only be performed by trained staff. The needle is usually placed in a vein in the hand, arm or bend of elbow. Occasionally, if there are no visible veins in the arms, the needle will be placed in a vein in a leg or leg. IV scalp is sometimes usedthey are in infants.
After inserting an intravenous needle into a vein, it can be connected to an IV line or a short piece of hollow hose called heplock. Line IV will be connected to a bag of fluids or medicines. Intravenous pole with a programmable pump is used for IV therapy.
There are complications that can occur when inserted by intravenous needle. If the needle nicks the side of the vein, it can cause blood to flow into the surrounding tissue. This is called the "blowing" vein. The vein eventually recovers, but the individual may have a great bruise in this area.
Further complications may include infection at the place of insertion. The US disease centers recommend changing intravenous needle every 72 to 96 hours to reduce the level of infection. If the cannula IV migrates outside the vein, intravenous fluids can insert into the surrounding tissues. This can cause swelling and pain. Some IV medicines can be extremely caustic and can inreality to cause to die the surrounding tissue.
As soon as intravenous needles are needed, it can be easily removed. Healthcare staff will put on gloves and removes the tape that holds an IV needle in place. He then carefully pulls out the plastic cannula from the vein. Sometimes it is necessary to put pressure in the place of insertion to stop bleeding. A small bandage will be placed in the place of insertion.
