The Procedural Work For The Cannula
- Method of Insertion
- The appropriate size of the cannula is selected, as the ideal size reduces the risk of injury and vein congestion.
- The suitable site for the cannula insertion is chosen.
- Simple washing with water and soap or rubbing hands with alcohol or an alcohol-based solution.
- The upper arm is tied with a pressure band (single-use tourniquet), preferably on the less-used arm.
- The insertion site is disinfected with a suitable antiseptic, ensuring that the skin at the insertion site is clean and that the insertion site is not touched after disinfection (sterile technique).
- If the first attempt fails, a new cannula should be used for the second attempt. The same cannula should not be re-inserted.
- After securing the cannula, the pressure band (tourniquet) is released, and the cannula is secured with a sterile dressing, noting the date of insertion.
- Dispose of sharp instruments in a designated safety container.
- Wash and dry hands after removing gloves.
Follow-up and Monitoring for IV Therapy to Prevent Infection:
- Avoid inserting a cannula in the veins of the legs, especially for diabetic patients.
- Regular monitoring of the insertion site for signs of swelling or infection.
- Keep the cannula insertion site clean and dry.
- Reassess the need for the cannula every 24 hours.
- The cannula should be removed in the following cases:
- When it is no longer needed.
- If any signs of inflammation appear.
- After 72-96 hours of insertion, unless it is difficult to insert a new cannula, such as in certain neonate cases, as long as there are no signs of infection.
- If the type of solution changes, the IV set should be replaced to prevent reactions between solutions.
- If there is no likelihood of a reaction between solutions, the same IV set can be used, but it must be removed from the empty solution bottle and placed in the new solution bottle directly after disinfecting the insertion point.
- The IV set should not be used for more than 72-96 hours (same duration as the cannula). Both the IV set and the cannula should be removed together when the duration ends or if they are no longer needed.
- If administering intravenous nutrition or lipid solutions, the IV set and cannula should be changed every 24 hours at most.
- The IV set and cannula should be changed immediately after blood transfusion or administration of blood products.
