HD is the most common renal replacement therapy for decades, for those who have end-stage RD and have not received renal transplantation. Intermittent HD is a very efficient method to decrease blood urea and creatinine as well as to treat volume overload. Intermittent HD can be performed temporarily in the setting of acute RD or permanently in the setting of chronic RD. In chronic RD, 3 sessions of 4 hours are usually prescribed to adequately substitute the renal function. A good vascular access is essential to perform HD. A temporary dual- or tri-lumen dialysis catheter has to be inserted into a central vein such as the internal jugular, the subclavian or the femoral vein.
