The Catheter VS The Cannula
The catheter and the cannula are easily confused. Although both can be used to deliver IV solutions, they are quite different. The catheter is a vinyl tube used for the delivery of nutritional fluids, IV medications, blood products and IV solutions for patients. The catheter cans also are used to drain the patient’s bladder or body cavities. The cannula is a small tube used to give patients fluids, blood transfusions and medications once inserted into a vhttps://www.jennsblahblahblog.com/the-pros-and-cons-of-medicare-is-it-worth-your-money/ein. Almost ninety percent of all hospital patients require intravenous therapy during their stay. A full description of both the catheter and the cannula are outlined below.
An IV catheter is used by medical professionals to provide venous access. When a patient is unresponsive, fluids and nutrients must be provided. Once the catheter has been placed in the vein, the patient can receive medication, blood samples can be taken efficiently and chemotherapy can begin. The access of the IV catheter must be solid because the veins are constructed of delicate tissues. Special techniques are used to insert a catheter due to the unidirectional blood flow. The catheter is an important part of modern medicine.
The IV catheter is used thousands of times per day in many hospitals. The specific type of catheter being used is critical. Venous access should only be conducted using a flawless catheter. This ensures the task can be completed safely, efficiently and effectively. The design of the catheter encompasses the smallest of details. In many cases, the catheter is inserted by a fully trained and experienced nurse. A catheter is sometimes inserted when a patient enters a hospital to ensure any necessary IV medications, blood products or fluids can be administered quickly.
The IV cannula is flexible, small and placed into a vein. The vein is usually located in the arm or on the back of the hand. One end of the cannula is placed into the vein, the other is attached to a small valve. The cannula is frequently used by hospitals to provide patients with fluids and medications directly into the bloodstream or to take blood samples for testing. Certain medications only require a few minutes for delivery. Others require a special pump and several hours for administration. A tourniquet is applied prior to inserting the cannula.
The medical professional locate the vein, inserts the IV cannula and removes the tourniquet. The cannula is fast and easy to use provided the patient remains relaxed and still. If an individual has a fear of needles, a specialist is often called to insert the cannula. Once the cannula has been placed, the needle is removed. All that remains is the actual catheter in that vein. The tape is used to secure the IV cannula and ensure it remains in place. The cannula must be kept clean and dry. The cannula does not cause the patient any pain. In most cases, the cannula remains effective for several days.
The cannula must be checked every day for any signs of swelling or redness. The nurse will ensure the patient is not feeling any pain from the device. If there is an issue with the cannula, it will be removed and a new one inserted. Removing a cannula only requires about a minute. The nurse begins by removing the tape. The flexible tube is then removed. Gauze is held against the area for a couple of minutes to stop any bleeding. A small amount of bleeding is common but should stop quickly. In some instances, a band-aid is applied to the area once the gauze has been removed.
