O acesso vascular para pacientes que necessitam de tratamento com hemodiálise deve oferecer um fluxo sangüíneo efetivo, rápido, constante e capaz de ser utilizado repetidas vezes. A fístula arteriovenosa é o acesso vascular de escolha para a realização das sessões de hemodiálise, tanto pelo fluxo de sangue que oferece quanto pela baixa taxa de infecção e de trombose. O uso de cateter venoso central, nesses pacientes, tem sido utilizado como o primeiro acesso vascular. Esses cateteres podem ser divididos em tunelizados e não-tunelizados. Os tunelizados têm um trajeto subcutâneo antes de penetrar na veia e são utilizados nos pacientes que permanecerão com cateter por tempo mais prolongado. Os cateteres não-tunelizados são indicados nas situações que requerem uma menor permanência, como na insuficiência renal aguda.
Vascular access for patients requiring hemodialysis should provide effective, rapid and constant blood flow and be capable of repeated use. The arteriovenous fistula is the vascular access of choice for hemodialysis because it offers increased blood flow with lower rates of infection and clotting. Central venous catheters are often the first vascular access used. These catheters may be divided into tunneled or non-tunneled. Tunneled catheters travel under the skin prior to penetrating the vein and are used in patients who need to maintain vascular access for a longer period of time. Non-tunneled catheters are indicated for short-term use, such as in acute renal failure.
