IV medication isn't inserted directly; rather, a thin plastic tube called an IV catheter is inserted into a vein, allowing for the delivery of medication or fluids. This process is typically performed by a trained healthcare professional in a hospital or clinic setting.
The IV Insertion Process
- Vein Selection: A suitable vein is chosen, usually located in the wrist, elbow, or the back of the hand.
- Needle Insertion: A needle is inserted into the selected vein.
- Catheter Advancement: A catheter (a thin, flexible tube) is then carefully advanced over the needle into the vein.
- Needle Removal: Once the catheter is securely positioned, the needle is removed, leaving the catheter in place.
- Securement: The catheter is then secured with a dressing to prevent accidental removal and infection. The area is cleaned and covered to keep out air, dirt, and germs. Sometimes numbing medicine is applied before the process begins.
Types of IV Access
While peripheral IVs (inserted in veins in the arms or hands) are common, there are other types of vascular access devices for long-term IV therapy, including:
- PICCs (Peripherally Inserted Central Catheters): These are longer catheters inserted into larger veins in the arm and threaded into a central vein near the heart.
- Ports: These are small devices surgically implanted under the skin with a catheter leading to a central vein.
Important Considerations
- Sterility: Maintaining sterility throughout the procedure is crucial to prevent infection.
- Medication Administration: Once the IV catheter is in place, medication is administered through it using various techniques, such as a syringe (IV push) or an infusion pump (for continuous or intermittent infusions).
- Monitoring: Following IV insertion, the patient's site and overall condition are closely monitored for any complications.
