Long, slow dialysis

Long slow hemodialysis (3 x 8 hours/week) has been used in Tassin for 30 years without significant change in the method. It provides excellent results in terms of morbidity and mortality. The better survival than usually reported on shorter dialysis is mainly due to lower cardiovascular mortality, The nutritional state of the patient is good, as well as the correction of anemia with low doses of EPO, But the main feature concerns blood pressure; hypertension is very well controlled without need for antihypertensive medications, The gentle ultrafiltration provided by a long session time associated with a low salt diet and a moderate interdialytic weight gain allows for normalization of the extracellular fluid space in most patients (dry weight) without important intradialytic morbidity, This low salt diet has paradoxically been forgotten in recent years while shortened dialysis time renders it more necessary than ever.
