title: The impact of haemofiltration on the systemic cardiovascular response.
abstract: Convective transport across the dialysis membrane has long been known to be a good alternative to diffusion. Among the advantages of haemofiltration over conventional haemodialysis is a better cardiovascular stability. Haemofiltration has a more physiological response to fluid removal than haemodialysis: (i) blood volume may be better preserved, especially in patients with a compromised cardiac function; (ii) arterial peripheral resistances and venous tone increase; and (iii) myocardial contractility is neither depressed nor altered. We discuss the role of the different pathophysiological mechanisms in the disparity in cardiovascular reactivity between haemofiltration and haemodialysis.
