Tandem plasmapheresis and hemodialysis

Area of Science:

• Nephrology
• Critical Care Medicine

Background:

• Patients with renal failure often require plasmapheresis (PE) and hemodialysis.
• Performing these procedures separately is time-consuming, typically requiring 6-7 hours.

Purpose of the Study:

• To evaluate the feasibility and benefits of performing plasmapheresis and hemodialysis simultaneously.
• To reduce patient inconvenience and hospital costs associated with separate procedures.

Main Methods:

• Developed a tandem extracorporeal circuit where the plasmafilter is placed after the hemodialyzer.
• Conducted 8 tandem PE/hemodialysis sessions in 2 patients requiring both treatments.

Main Results:

• The combined procedure time was equivalent to routine hemodialysis.
• Reduced priming fluid volume compared to separate procedures.
• No major complications, only transient hypotension managed with saline infusion.

Conclusions:

• Tandem plasmapheresis/hemodialysis is a safe, efficient, and cost-effective method for patients needing both therapies.
• This combined approach offers significant convenience for patients and economic benefits for hospitals.
