Intravenous Catheter insertion and basic knowledge of Intravenous therapy
The main purpose of Intravenous catheter insertion or IV catheter insertion is to infuse medicines to perform intravenous therapy in the human body. In some cases where the medicines, fluids or other essential and important liquids are not being taken orally, in that case, intravenous therapy is used to supply such important elements directly to our body.
The therapy is carried out by inserting a needle in the vein and then connecting it with a connector and then the fluid/liquid administrator. The vein selection should be carried out very carefully to insert I.V Catheter. In adults, the needle is inserted in arms and hands, but in children, it is mostly inserted in feet. In adults, the feet are not chosen for intravenous therapy because by doing so there is a risk of thrombophlebitis. The hands should be properly sanitized before starting the therapy.
The selected vein area should be properly cleaned with the help of a sanitizer; the nursing staff should also clean their hands before inserting the I.V Catheter to the patient. The nursing staff should avoid choosing Melin cubital vein and cephalic vein, because selecting these veins can cause nerve damage, they should use most distal site possible.
For the preparation of I.V catheter insertion, important things which are required are Tourniquet, absorbent pad, chlorhexidine swales, 2 pair of latex-free gloves, proper size over the needle catheter, I.V needleless connector, I.V extension tubing, barrier solution, I.V adhesive securement device, transparent tape, 2X2 sterile gauze.
As the essential medicines, fluids, liquids or drugs are supplied to the patient after inserting the I.V catheter, the patient may feel cold sensation and salty taste in the mouth. As a doctor or nursing staff, they should always educate the patient about the procedure and possible complications before venipuncture.
The doctors and the nursing staff should also tell the patient about the process and the pain associated with insertion. Further, it has been seen in most of the cases where many patients think the needle remains in the vein after insertion. It is important to emphasize that only the soft, flexible catheter portion remains in the vein and that they will be able to move the limb freely without any harm.
An I.V Catheter can come in many shapes and sizes, which can be used according to the type of therapy. Some I.V Catheter may have wings for the extra grip during insertion; some I.V Catheter has an injection port so that additional medicine can be given to a patient without disturbing or stopping the flow of liquid.
Nowadays, the nursing staff is very well aware of important things that need to be followed during the I.V catheter insertion. This not only has increased the efficiency of the hospitals but has also decreased the cases of infection and needlestick injuries.
