Performing an intravenous (IV) injection requires specialized medical training and should only be done by qualified healthcare professionals. The following is a simplified overview for informational purposes only and should NOT be used to attempt an IV injection without proper training. Incorrect technique can lead to serious complications.
Steps Involved in Intravenous Injection (Simplified Overview):
This is a highly simplified overview. Actual medical procedures are far more complex and require strict adherence to safety protocols.
-
Preparation:
- Gather necessary supplies: IV catheter (needle with a small plastic tube), antiseptic solution (e.g., alcohol wipes), sterile gloves, tourniquet, sterile dressing, tape, and the medication to be administered.
- Verify the medication order and ensure it's the correct drug, dose, route, and time.
- Explain the procedure to the patient and answer any questions.
- Wash hands thoroughly and put on sterile gloves.
-
Vein Selection and Preparation:
- Apply a tourniquet to the patient's arm to make the veins more prominent.
- Choose a suitable vein (typically in the arm, hand, or occasionally the foot). Palpate the vein to assess its size and condition. Avoid areas of injury or infection.
- Clean the injection site thoroughly with an antiseptic solution using a circular motion, starting at the center and moving outward. Allow the solution to dry completely.
-
Catheter Insertion:
- Hold the skin taut below the injection site to stabilize the vein.
- Insert the IV catheter through the skin and into the vein at a shallow angle (typically 15-30 degrees), with the bevel (angled opening) of the needle facing upward.
- Observe for a "flash" of blood in the catheter hub, indicating successful vein entry.
-
Catheter Advancement and Needle Removal:
- Advance the catheter slightly further into the vein.
- Stabilize the catheter hub and carefully retract the needle, leaving the plastic catheter in place within the vein.
- Activate the safety mechanism on the needle (if equipped) to prevent accidental needlestick injuries. Dispose of the needle immediately in a sharps container.
-
Securing the Catheter:
- Connect the appropriate IV tubing or access cap to the catheter hub.
- Flush the catheter with a small amount of sterile saline solution to ensure patency (that it's not blocked).
- Secure the catheter to the patient's skin with sterile dressing and tape to prevent dislodgement.
-
Medication Administration:
- Administer the prescribed medication according to the physician's orders and established protocols.
- Monitor the patient for any adverse reactions.
-
Documentation:
- Document the procedure, including the date, time, medication administered, dose, route, injection site, and the patient's response.
Important Considerations:
- Sterility: Maintaining strict sterile technique is crucial to prevent infection.
- Patient Safety: Monitor the patient closely for any signs of adverse reactions, such as allergic reactions or infiltration (fluid leaking out of the vein).
- Training and Competency: Only trained and qualified healthcare professionals should perform IV injections.
- Complications: Potential complications include infection, bleeding, nerve damage, and air embolism.
