Can FFP Be Given During Hemodialysis?
Yes, fresh frozen plasma (FFP) can be administered during hemodialysis, though this is typically done in specific clinical scenarios rather than as routine practice, and the decision should be based on the indication for FFP rather than the concurrent need for dialysis.
Technical Feasibility
FFP administration during hemodialysis is technically feasible and has been documented in clinical practice. The case literature demonstrates that FFP can be given concurrently with hemodialysis sessions when clinically indicated 1. In patients requiring plasma exchange with FFP replacement who also need dialysis, short heparin-free hemodialysis sessions can be performed to manage metabolic complications from citrate load 2.
Clinical Indications for FFP
The decision to give FFP should be based on established indications, not simply because a patient is on dialysis. FFP is primarily indicated for major hemorrhage, disseminated intravascular coagulation with bleeding, warfarin reversal when prothrombin complex is unavailable, and as replacement fluid for therapeutic apheresis 3.
Key Points About FFP Use:
- FFP should NOT be used prophylactically to correct abnormal coagulation tests prior to low-risk procedures in critically ill patients 4, 3
- Abnormal PT/APTT are poor predictors of bleeding in hemodynamically stable critically ill patients 3
- FFP should not be used solely for volume replacement 3
Contraindications and Precautions
Relative Contraindications:
- Volume overload risk: Patients on hemodialysis often have fluid restrictions, and FFP administration adds significant volume (typically 10-15 mL/kg)
- Citrate toxicity: FFP contains citrate as a preservative, which can accumulate in patients with renal failure. When combined with citrate anticoagulation during dialysis or plasma exchange, this can cause metabolic alkalosis 2
- Transfusion-associated circulatory overload (TACO): Dialysis patients are at higher risk
Management Strategy:
If FFP is indicated in a dialysis patient:
- Consider timing FFP administration during or immediately after hemodialysis to manage volume
- Monitor for metabolic alkalosis, particularly if citrate anticoagulation is used
- Short heparin-free hemodialysis can correct citrate-induced alkalosis if needed 2
- Ensure ABO compatibility (donor and recipient blood groups should match) 3
Specific Scenarios to Avoid FFP:
Based on recent guidelines, avoid routine prophylactic FFP transfusion in the following situations 4:
- Central venous catheter or arterial line insertion in coagulopathic patients (unless INR >1.5-2 for lumbar puncture)
- GI endoscopy in patients with portal hypertension-related bleeding
- Most bedside procedures in critically ill patients
Common Pitfalls:
- Do not reflexively give FFP for elevated INR/PT in dialysis patients without active bleeding or high-risk procedures
- Remember that coagulation abnormalities in renal failure patients don't necessarily predict bleeding risk
- Avoid using FFP as a volume expander in hypovolemic dialysis patients
The key principle is that hemodialysis itself is not a contraindication to FFP, but the indication for FFP must be strong enough to justify the risks, particularly volume overload and metabolic complications in this vulnerable population.
