To insert a scalp vein, you should slowly and gently insert the needle parallel to the vessel at a 20 to 30-degree angle above the skin until blood appears in the chamber. The tourniquet can be removed after this. Next, advance the needle slightly to confirm it is in the vein. Allow the infant to calm down before threading the catheter.
Detailed Steps for Scalp Vein Insertion
Here's a breakdown of how to insert a scalp vein:
-
Preparation:
- Gather all necessary supplies, including the appropriate size scalp vein needle, a tourniquet, antiseptic solution, gauze, and tape.
- Clean the selected site with antiseptic solution.
-
Vein Identification:
- Identify a suitable vein on the infant's scalp.
- Apply the tourniquet to help the vein become more prominent.
-
Needle Insertion:
- Angle: Insert the needle slowly and gently, parallel to the vessel, at a 20 to 30-degree angle above the skin.
- Insertion: Advance the needle until you see blood in the flash chamber of the needle.
-
Tourniquet Removal
- After seeing blood in the flash chamber, the tourniquet may be removed.
-
Confirmation:
- Slightly advance the needle further into the vein to make sure it is correctly placed.
-
Catheter Advancement:
- Allow the infant to calm down before attempting to thread the catheter through the needle into the vein.
Important Considerations
- Gentleness: Always handle the infant gently to minimize discomfort.
- Positioning: Ensure the infant is positioned comfortably and securely.
- Calming: Allow the infant time to calm down between steps, especially before threading the catheter.
- Observe: Continuously monitor the insertion site for any signs of complications such as hematoma, infiltration, or irritation.
