Management of Hemodialysis Complications
Introduction to Hemodialysis Complications
- The American Journal of Kidney Diseases recommends reducing dialysate temperature from 37°C to 34-35°C to increase peripheral vasoconstriction and cardiac output, decreasing symptomatic hypotension incidence from 44% to 34% 3, 4, 1
- The National Kidney Foundation (NKF) suggests maintaining hemoglobin at 11 g/dL to improve oxygen-carrying capacity and cardiovascular compensation 3, 4, 1, 2
Hypotension Management
- The American College of Cardiology recommends immediately stopping or reducing ultrafiltration, placing the patient in Trendelenburg position, and administering supplemental oxygen to address acute intradialytic hypotension 1, 2
- The American Journal of Kidney Diseases suggests administering midodrine (oral selective α1-adrenergic agonist) within 30 minutes before dialysis initiation to increase peripheral vascular resistance and enhance venous return, reducing hypotensive events 3, 4, 1
Muscle Cramps Management
- The American Journal of Kidney Diseases recommends reducing ultrafiltration rate by extending treatment time and increasing dialysate sodium concentration to 148 mEq/L early in the session to address muscle cramps 3, 5
- The National Kidney Foundation (NKF) suggests correcting anemia to hemoglobin levels per NKF-K/DOQI guidelines to improve oxygen-carrying capacity and reduce cramp frequency 3, 5
Nausea and Vomiting Management
- The American Journal of Kidney Diseases recommends switching from acetate-containing to bicarbonate-containing dialysate to minimize nausea and vomiting 3, 4
- The American College of Cardiology suggests reducing dialysate temperature to 34-35°C to improve hemodynamic stability and reduce associated symptoms 3, 4
Vascular Access Issues
- The American Journal of Kidney Diseases recommends reviewing extracorporeal pressures on hemodialysis log, particularly prepump arterial pressure for values ≥200 mmHg indicating access problems 3
- The National Kidney Foundation (NKF) suggests assessing for dialyzer clotting which may indicate inadequate anticoagulation or access dysfunction 3
Patient Adherence and Behavioral Optimization
- The American Journal of Kidney Diseases recommends evaluating reasons for patient nonadherence including missed sessions, late arrivals, treatment interruptions, or premature terminations 3
- The American College of Cardiology suggests modifying hemodialysis prescription to prevent intradialytic symptoms that adversely affect patient comfort and adherence, without compromising delivered dose 3
