Use of lidocaine iontophoresis is effective for reducing pain and alleviating distress during venipuncture in children. [19] A needle-free powder lignocaine delivery system has been shown to decrease the pain of venipuncture in children.
The butterfly's precise placement facilitates venipuncture of thin, "rolling", fragile, or otherwise poorly accessible veins. The butterfly's shallow-angle insertion design facilitates venipuncture of very superficial veins, e.g. hand, wrist, or scalp veins (hence name "scalp vein" set).
Phlebotomy is the process of making a puncture in a vein, usually in the arm, with a cannula for the purpose of drawing blood. [1] The procedure itself is known as a venipuncture , which is also used for intravenous therapy .
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
A venipuncture performed using a vacutainer. A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid from the body for analysis.. Blood flows throughout the body, acting as a medium that provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disp
The median cubital vein is routinely used for phlebotomy and venipuncture (taking blood), and as a site for an intravenous cannula. [6] This is due to its particularly wide lumen, and its tendency to remain stationary upon needle insertion. [6] It becomes prominent when pressure is applied upstream, which makes needle insertion easier. [5]
Along with other superficial veins in the forearm, the basilic vein is an acceptable site for venipuncture.Nevertheless, IV nurses sometimes refer to the basilic vein as the "virgin vein", since with the arm typically supinated during phlebotomy the basilic vein below the elbow becomes awkward to access, and is therefore infrequently used.
Vacutainers are widely used in phlebotomy in developed countries due to safety and ease of use. Vacutainers have the advantage of being prepared with additives, allowing easy multi-tube draws, and having a lower chance of hemolysis. [18] In developing countries, it is still common to draw blood using a syringe or syringes.
