Vascular access systems are intended for a series of diagnostic tests and treatments such as central venous pressure readings, blood sampling, fluid infusion, blood transfusion, parenteral and drugs administration such as chemotherapeutic agents, analgesics, antibiotics. Vascular access systems can be defined as the material which is implanted subcutaneously in a region over the upper chest wall, having a dwell time of nearly 14 days, with the catheters inserted in the sub clavian vein, jugular vein, or basilic vein. Central Venous Access systems are essential for the care of many sick children. In order to reduce the risk of infection and thrombosis and also to increase the line longevity, appropriate type of catheter must be selected and inserted in a standardized procedure. Vascular access systems market covers implantable-ports, Huber needles, (PICCs) peripherally inserted central catheters, (CVCs) central venous catheters, dialysis catheters, needleless connectors, needles and syringes. The usage of these medical systems depends on various medical conditions and its requirements that may include the purpose for its requirements, size of the device, the duration of time it needs to be in-situ. Peripheral vascular access systems are the most appropriate for short term therapies as they cause less irritation. A peripherally inserted central catheter is inserted through antecubital fossa vein, which may be basilic or cephalic, further progresses through the superior vena cava. The position of the catheter’s tip is radiologically confirmed. The procedure are relatively easy to insert. This makes them a potentially more economically option. The risk involved for the rate of thrombosis and sepsis is lowered. The risk of large vein perforation and pneumothorax is also reduced, which is linked to centrally inserted catheters. Whereas central vascular access systems are used in cases like medicines having greater pH than 9.0 or less than 5.0, parentral nutrition with...
