veinipunktio

Veinipunktio, also known as venipuncture or phlebotomy, is a medical procedure that involves the insertion of a needle into a vein, typically for the purpose of drawing blood. This blood can then be used for various diagnostic tests, therapeutic purposes, or transfusions. Veinipunktio is a common and essential procedure in healthcare settings.

The most common site for veinipunktio is the antecubital fossa, located on the inner surface of the elbow. Other veins may be used depending on the patient's condition and the purpose of the procedure. Before the needle is inserted, the chosen vein is usually made more prominent by applying a tourniquet, which temporarily restricts blood flow. The skin over the vein is then cleaned with an antiseptic to prevent infection.

Once the needle is successfully inserted into the vein, blood is collected into a sterile tube or syringe. After the required amount of blood is drawn, the tourniquet is released, and the needle is withdrawn. Pressure is then applied to the puncture site to stop any bleeding, and a bandage is typically placed over the area.

Veinipunktio is generally considered a safe procedure. However, potential complications, though rare, can include bruising, swelling, infection at the puncture site, or fainting. Trained healthcare professionals, such as nurses, phlebotomists, or doctors, perform veinipunktio to ensure patient safety and obtain accurate results. The procedure is crucial for diagnosing a wide range of medical conditions and monitoring treatment efficacy.
