Aperipherally inserted central catheters is a type of intravenous access, whichis used for quick administration of fluids or for administering drugs thatcannot be administered directly into the body. These types of catheters areinserted into a large vein in the body outside the bladder. This type ofcatheter is often used when the needle is not appropriate for the intendedplacement or when the insertion into the body requires a lengthy period. Thistype of catheter can also be referred to as a Peripheral Nerve Injection (PNI).
Anexample of a peripherally inserted central catheter is the vena cava, which isa common fluid used in the treatment of organ failure, chronic obstructivepulmonary disease, and other ailments. The catheter is inserted into theinferior vena cava, which is an artery in the body's heart. This is one of themajor branches of the heart. It carries the blood from the heart back to thelungs through it. In many cases, the inferior vena cava is blocked by scartissue or other problems. To ease this blockage, a patient might receive aPeripheral Vena Cascading Catheter (PVC) or a Venous Vacuum Aspiration (CVCA).
Anotherexample of a peripherallyinserted central catheter is the pericardial catheter, which is used toadminister the medication directly into the heart. Sometimes, the medicationhas to be administered into the upper extremity due to the blockage of thevenous node. In this instance, the medical technician will open the pericardialspace with a small hollow needle called a pricker. Then, a catheter tube isinserted into the upper extremity via this needle, which is then inflated.
