Hemodialysis Guidelines for End-Stage Kidney Disease

Introduction to Hemodialysis

The American Journal of Kidney Diseases recommends a standard hemodialysis prescription for patients with end-stage kidney disease, including three sessions per week, each lasting a minimum of 3 hours, targeting a single-pool Kt/V of 1.4 per session, and using biocompatible high or low flux membranes 1, 2, 3

The National Kidney Foundation suggests that three times per week is the standard frequency for all patients requiring hemodialysis unless significant residual kidney function is present 4, 5
A minimum session duration of 3 hours is recommended for patients with low residual kidney function 1, 2, 3, 6
Twice-weekly hemodialysis is inadequate unless residual kidney function is substantial, and this residual function must be monitored serially to guide appropriate timing for transition to thrice-weekly sessions 4, 5, 7

The prescribed Kt/V should be 1.3 to ensure the delivered dose does not fall below the minimum adequate level 4, 5
A target single-pool Kt/V of 1.4 per session is recommended for thrice-weekly treatments 1, 2, 3
A minimum delivered spKt/V of 1.2 must be achieved 1, 2, 3

Biocompatible membranes, either high or low flux, should be used for intermittent hemodialysis 1, 2, 3, 6

Consider extending session duration or increasing frequency beyond the standard prescription for patients with large interdialytic weight gains, high ultrafiltration rates, poorly controlled blood pressure, difficulty achieving dry weight, or poor metabolic control 1, 2, 3, 6

Prescribe ultrafiltration rates that balance achieving euvolemia and adequate blood pressure control while minimizing hemodynamic instability and intradialytic symptoms 1, 2, 3, 6, 8
Combine dietary sodium restriction with adequate sodium/water removal to manage hypertension, hypervolemia, and left ventricular hypertrophy 1, 2, 3, 6

In patients with significant residual kidney function, dialysis dose may be reduced provided residual kidney function is measured periodically 1, 2, 3, 6
For non-thrice-weekly schedules, target a standard Kt/V of 2.3 volumes per week with minimum delivered dose of 2.1, including contributions from ultrafiltration and residual kidney function 1, 2, 3

Short frequent hemodialysis may be offered after discussing potential quality of life benefits and risks 1
Home long hemodialysis may be considered for patients preferring this for lifestyle considerations, with counseling about increased vascular access complications and caregiver burden 1

Beyond Kt/V alone, adequate dialysis must address potassium removal, correction of acidosis, adequate protein/caloric intake to prevent malnutrition, and sufficient fluid removal to achieve euvolemia 4, 5, 7
