Annotated Bibliography On Vascular Access Essay - 972 Words

Vascular Access Usually, accessing vascular structures is done through a needle to puncture the vessel percutaneously, followed by a wire introduced through the needle to secure the vascular access. The needle is then removed and a sheath is advanced over the wire. Vascular sheaths are hollow structures with a built in diaphragm to prevent bleeding. Catheters are then placed into and out of the sheath with a minimal loss of blood.11 Access to the Cardiovascular System Femoral arterial and venous access is traditionally the method of choice in infancy. The right and/or the left groins may be used. This port of access provides advantage of being away from the thoracic region for ease of catheter manipulation away from the radiographic cameras surrounding the child’s thorax. Umbilical arterial and venous access can be used in newborn babies up to 7 days of age. Other alternative route for arterial access includes: carotid artery, brachial artery, and axillary artery. On the other hand, alternative venous access includes: internal jugular vein, subclavian vein, axillary vein, and transhepatic venous access. Alternative vascular access (ARVA) is occasionally required due to the lack of femoral vascular patency or the need to position the catheter at a particular trajectory not provided through the traditional femoral access. The use of ARVA is safe and effective for performing a wide variety of interventions across. In addition, its use may imp rove the results of selected
