How to Use a Butterfly Needle
When using a butterfly needle, it is critical to follow the proper steps to avoid hemolysis, nerve damage, or patient discomfort. Follow the steps below for a safe procedure:
- Wash your hands and then put on a sterile pair of gloves.
- Attach the connector to a vacuum tube or a collection bag.
- Tie a tourniquet around the patient’s arm and look for a vein.
- When you have found a vein, disinfect the needle site and wait for it to dry before inserting the needle.
- Insert the butterfly needle into the vein at a 30-degree angle. If you see blood through the tube, the needle is inserted correctly. If not, the vein collapsed, and you must look for another vein.
- Once the vacuum tube is full of blood, remove the tourniquet.
- Remove the needle and bandage the draw site.
- Dispose of the needle properly and label the blood sample.
