Long 3 x 8 hr dialysis: a three-decade summary

Area of Science:

• Nephrology
• Internal Medicine
• Clinical Medicine

Background:

• Long hemodialysis (HD) has been practiced for 35 years with positive outcomes.
• The Tassin regimen emphasizes extended dialysis sessions (3 x 8 hours/week).

Purpose of the Study:

• To evaluate the long-term efficacy and benefits of a specific long hemodialysis protocol.
• To highlight the impact of long HD on cardiovascular mortality, blood pressure control, and toxin clearance.

Main Methods:

• Utilized a standardized long hemodialysis protocol (3 x 8 hours/week).
• Focused on achieving tight extracellular volume normalization (dry weight) and effective blood pressure management.
• Monitored small and middle molecule clearance, nutrition, anemia, and serum phosphorus levels.

Main Results:

• Excellent patient morbidity and mortality results, particularly lower cardiovascular mortality.
• Effective blood pressure control, including drug-free hypertension management and reduced intradialytic hypotension.
• High clearance of small and middle molecules, leading to improved nutrition, anemia correction, and better serum phosphorus and potassium control with minimal medication.

Conclusions:

• Long hemodialysis, especially overnight sessions, offers optimal treatment for renal failure by addressing multiple patient abnormalities.
• This cost-effective approach significantly improves survival and quality of life compared to standard dialysis.
• While patient willingness for overnight dialysis may decrease, the benefits of longer sessions remain substantial.
