AbstractManagement of the vascular access (VA) for renal replacement therapy (RRT) in acute renal failure (ARF) patients is faced with a twofold problem: first, the creation of an angio-access that is adequate for RRT in the acute setting; second, the preservation of the patient's vascular network in order not to preclude further use of the vessel in the event of evolution to chronic renal failure. Central venous catheters are the preferred VA for RRT in the intensive care setting. Semi-rigid double-lumen polyurethane catheters may be considered for short-time use (up to 2-3 weeks). Soft silicone double-lumen or twin-catheters, preferably with subcutaneous tunnelling, are highly desirable for prolonged RRT (over 3 weeks). The femoral route is the first option in the presence of associated risk factors (respiratory failure, pulmonary oedema, bleeding...). The internal jugular route should be considered for mid-term use in order to facilitate the patient's mobilization and to reduce the risk of infection. The subclavian route should be avoided because of the risk of stenosis and/or thrombosis of the outflow vein. Catheter insertion must be performed by a trained physician with ultrasound guidance using either skin mapping or continuous vein guidance. Catheter handling and care should comply with best practice guidelines and should be part of a continuous quality improvement programme in order to reduce catheter-related morbidity. Preservation of the upper limb vascular network of the patient consists of sparing the native vessels (artery and vein) of the patient and preserving the functionality of the permanent VA in chronic renal failure patient. This 'lifeline' of chronic renal failure patients may be maintained by preventing inflammation, infection and thrombosis of the superficial vessels of the arm and forearm of patient.
