Double Pump Sequential Constant Citrate Anticoagulation in General Hemodialysis

Area of Science:

• Nephrology
• Hematology
• Medical Devices

Background:

• Hemodialysis is a critical treatment for end-stage renal disease (ESRD).
• Anticoagulation is essential during hemodialysis, especially in patients with bleeding complications.
• Citrate anticoagulation is commonly used, but its efficacy with different pump systems requires investigation.

Purpose of the Study:

• To compare the safety and efficacy of single-pump versus double-pump sequential anticoagulation using constant citrate in hemodialysis.
• To evaluate the impact on anticoagulation effectiveness and patient safety.

Main Methods:

• A randomized study involving 32 ESRD patients with hemorrhage.
• Patients were divided into single-pump (n=17) and double-pump (n=15) groups.
• Coagulation in the dialyzer and intravenous pot, serum calcium levels, and single-pool Kt/V were monitored.

Main Results:

• Double-pump anticoagulation showed significantly fewer intravenous pot coagulations compared to the single-pump group.
• Serum calcium levels behind the intravenous pot were lower at 2 hours in the double-pump group, returning to baseline post-dialysis.
• Both methods achieved normal single-pool Kt/V values without statistically significant differences, and no adverse reactions were reported.

Conclusions:

• Double-pump segmented sequential anticoagulation is superior to single-pump for intravenous pot anticoagulation in hemodialysis patients with bleeding.
• This dual-pump method represents a simple, effective, and safe anticoagulation strategy for clinical hemodialysis.
