A scalp vein set, commonly known as a butterfly needle, is a medical device designed for venipuncture, particularly in patients with delicate or difficult-to-access veins. This device is widely used in pediatric, geriatric, and oncology patients due to its precision and comfort.
Parts of a Scalp Vein Set
A standard scalp vein set consists of the following components:
Needle: A short, thin, stainless-steel needle designed to minimize patient discomfort.
Wings: Flexible plastic "butterfly" wings for easy handling and stabilization.
Tubing: A flexible, transparent tube that connects the needle to the connector.
Connector: A luer lock or luer slip fitting to attach to a syringe or IV line.
Protective Cap: Covers the needle to ensure sterility before use.
Types of Scalp Vein Sets
Several types of scalp vein sets are available to suit different clinical needs:
Luer Lock Scalp Vein Set:
Features a threaded connection for a secure fit with syringes or IV lines.
Reduces the risk of leakage and accidental disconnection.
Luer Slip Scalp Vein Set:
Provides a simple push-fit connection for quick attachment and removal.
Ideal for short-term use in clinical settings.
Disposable Scalp Vein Set:
Designed for single-use applications to prevent cross-contamination.
Commonly used in hospitals and diagnostic labs.
Safety Scalp Vein Set:
Equipped with a safety mechanism to prevent needlestick injuries.
Ensures compliance with health and safety regulations.
Uses of Scalp Vein Set
Scalp vein sets are utilized for various medical procedures, including:
Blood Collection: Widely used in phlebotomy for drawing blood samples.
Intravenous (IV) Therapy: Ideal for administering fluids and medications.
Pediatric and Geriatric Care: Preferred for patients with fragile veins.
Oncology Treatments: Used in chemotherapy administration to minimize trauma.
Scalp Vein Set Needles Sizes and How to Choose
| Needle Gauge | Needle Diameter | Needle Length | Common Use | Recommended for | Considerations |
| 24G | 0.55 mm | 0.5 - 0.75 inches | Small veins, neonates, pediatric patients | Neonates, infants, small children, elderly | Smallest available, less painful, but slower infusion. Ideal for fragile veins. |
| 22G | 0.70 mm | 0.5 - 0.75 inches | Pediatric patients, small veins | Children, smaller veins in adults | A balance between speed and comfort for pediatric and smaller adult veins. |
| 20G | 0.90 mm | 0.75 - 1 inch | Adult veins, routine infusions | Adults with smaller veins or when quick access is needed | Standard size for most adult veins. Can handle moderate infusion rates. |
| 18G | 1.20 mm | 1 - 1.25 inches | Emergency, large fluid infusions, blood draws | Adults needing rapid fluid resuscitation or blood transfusions | Large bore, fast infusion, used in emergencies or trauma. |
| 16G | 1.65 mm | 1 - 1.25 inches | Trauma, large volume fluid resuscitation | Trauma patients, surgeries, or critical care | Very large bore, used for rapid fluid administration or blood transfusions. |
Additional Considerations:
Needle Length: The needle length typically depends on the patient's size and the location of the vein. A shorter length (0.5 - 0.75 inches) is usually suitable for infants, small children, or superficial veins. Longer needles (1 - 1.25 inches) are needed for larger veins or in patients with thicker skin.
Choosing the Right Length: The length of the needle should be sufficient to access the vein, but not too long as to cause unnecessary trauma. For children, shorter needles are often used to avoid deep puncture into underlying tissues.
Practical Tips for Selection:
Smaller Children/Infants: Use 24G or 22G needles with shorter lengths (0.5 inches).
Adults with Normal Veins: 20G or 18G with lengths of 0.75 to 1 inch will be appropriate.
Emergencies/Trauma: 18G or 16G needles with longer lengths (1 inch) for rapid fluid resuscitation.
