Vacuum Tube This is the basic, and most often performed, type of venipuncture procedure. It is also referred to as the Evacuated Phlebotomy Method. Using a system known as needle and sheath, the phlebotomist is able to fill several tubes from a single venipuncture.

The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body, because they are introduced directly into the circulation. Intravenous therapy may be used for fluid volume replacement, to correct electrolyte imbalances, to deliver medications, and for blood transfusions.

There are several types of central venous catheters. PICC line. A peripherally inserted central catheter, or PICC line (say "pick"), is a central venous catheter inserted into a vein in the arm rather than a vein in the neck or chest.

The most common routes of insertion include the internal jugular, external jugular, subclavian, basilic, and femoral veins via a percutaneous approach [2]. The optimal location of a central venous catheter (CVC) is within the long axis of the superior vena cava (SVC) outside of the right atrium [3].

Gently squeeze up a well-defined fold of skin and fat with the thumb and index finger. Hold the shaft of the syringe in a dart fashion, insert needle directly through the skin at a right angle (90-degree angle) quickly just into the fatty layer. Move hand into position to direct plunger.

First, TPN is administered through a needle or catheter that is placed in a large vein that goes directly to the heart called a central venous catheter. Since the central venous catheter needs to remain in place to prevent further complications, TPN must be administered in a clean and sterile environment.

Cannulation of the cephalic, basilic, or other unnamed veins of the forearm is preferrable. The three main veins of the antecubital fossa (the cephalic, basilic, and median cubital) are frequently used. These veins are usually large, easy to find, and accomodating of larger IV catheters.

Blood is most commonly obtained from the superficial veins of the upper limb. The median cubital vein, which lies within the cubital fossa anterior to the elbow, is close to the surface of the skin without many large nerves positioned nearby.

A tourniquet is used by the phlebotomist to assess and determine the location of a suitable vein for venipuncture. ... The tourniquet is applied three to four inches above the needle insertion point and should remain in place no longer than one minute to prevent hemoconcentration.
