Management of Hemorrhagic Stroke in ESRD Patients
For ESRD patients with hemorrhagic stroke, prioritize aggressive blood pressure control to prevent hematoma expansion, avoid nephrotoxic agents including contrast dye and mannitol when possible, and optimize hemodynamic stability during dialysis sessions to prevent secondary brain injury.
Immediate Acute Management
Blood Pressure Control
- Target systolic blood pressure ≤140 mmHg to prevent hematoma expansion, though this must be balanced against the risk of hypoperfusion in ESRD patients who may have impaired cerebral autoregulation 1
- Avoid post-dialytic drops in systolic blood pressure greater than 30 mmHg, as these are associated with increased mortality and may worsen cerebral perfusion in the setting of acute hemorrhagic stroke 1
- Monitor blood pressure continuously during the acute phase, as ESRD patients demonstrate U-shaped mortality curves with both excessive BP reduction and inadequate control 1
Reversal of Coagulopathy
- Recognize that ESRD patients have paradoxical platelet dysfunction despite uremia, including proteolysis of GPIb receptors, defective von Willebrand factor interactions, and competitive inhibition of GPIIb/IIIa receptors by circulating fibrinogen fragments 1
- For patients on anticoagulation, reverse immediately with appropriate agents (vitamin K, prothrombin complex concentrate, or specific reversal agents depending on the anticoagulant used)
- Consider desmopressin (DDAVP) to temporarily improve platelet function in uremic patients, though evidence is limited 1
Avoid Nephrotoxic Interventions
- Do not use mannitol for intracranial pressure management in ESRD patients, as the FDA label explicitly warns that mannitol is contraindicated in well-established anuria due to severe renal disease and can cause irreversible renal failure 2
- Limit or avoid contrast-enhanced CT angiography when possible; if essential for surgical planning, do not delay imaging but recognize the "neurons over nephrons" principle applies less in hemorrhagic stroke where contrast adds limited acute management value 1
- Avoid nephrotoxic medications including aminoglycosides and NSAIDs during the acute phase 2
Dialysis Management During Acute Phase
Timing and Modality Considerations
- Continue intermittent hemodialysis (IHD) rather than switching to continuous renal replacement therapy (CRRT), as CRRT is associated with 28-32% increased mortality risk in ESRD stroke patients even after controlling for illness severity 3
- Avoid dialysis during the first 12-24 hours after hemorrhagic stroke onset when possible, as 38% of ischemic events in ESRD patients occur during or within 12 hours of dialysis due to hemodynamic instability 1, 4
- When dialysis cannot be deferred, implement strategies to minimize hemodynamic fluctuations 1
Hemodynamic Optimization During Dialysis
- Use dialysate cooling (0.5°C below core body temperature) to reduce hemodynamic instability and prevent secondary brain injury, as this prevents progression of brain white matter damage 1
- Minimize ultrafiltration rates and total fluid removal to avoid precipitous blood pressure drops that could extend the hemorrhage or cause secondary ischemia 1
- Monitor mean arterial pressure extrema point frequencies, as higher frequencies correlate with brain white matter damage and worse neurocognitive outcomes 1
Dialysate Composition
- Use dialysate calcium ≥1.50 mmol/L to maintain neutral or positive calcium balance while avoiding hypercalcemia, as recommended for intensive hemodialysis patients 1
- Consider hemodiafiltration with convection therapy if available, as this modality demonstrated 61% stroke risk reduction in chronic hemodialysis patients, likely through improved hemodynamic stability 1
Anemia Management
Hemoglobin Targets
- Target hemoglobin between 100-120 g/L using erythropoietin-stimulating agents, as the TREAT study demonstrated that higher targets (130 g/L) doubled both ischemic and hemorrhagic stroke risk compared to lower targets (90 g/L) 1
- Avoid aggressive correction of anemia in the acute hemorrhagic stroke phase, as rapid hemoglobin increases may paradoxically worsen outcomes 1
Surgical Considerations
Neurosurgical Intervention
- ESRD patients are eligible for neurosurgical evacuation of hemorrhage using the same criteria as non-ESRD patients (cerebellar hemorrhage >3 cm, deteriorating level of consciousness, or hydrocephalus) 1
- Be aware that ESRD patients have increased perioperative bleeding risk due to platelet dysfunction, but this should not preclude life-saving surgery 1
- Ensure adequate hemostasis during surgery, as uremic platelet dysfunction may prolong operative bleeding 1
Common Pitfalls and Caveats
Critical Errors to Avoid
- Do not use mannitol for cerebral edema management - this is explicitly contraindicated by FDA labeling in ESRD patients and can cause irreversible renal failure 2
- Do not assume neurologic changes during or after dialysis are metabolic; 38% of acute ischemic events in ESRD patients occur during or within 12 hours of dialysis, and hemorrhagic stroke can present similarly 4
- Do not switch to CRRT reflexively for "better control" - this is associated with significantly increased mortality in ESRD stroke patients 3
Monitoring Requirements
- Monitor serum sodium closely, as mannitol (if inadvertently used) can cause severe hypernatremia or worsen pre-existing hyponatremia through fluid shifts 2
- Assess for hypotension, hyponatremia, or hypoglycemia at symptom onset, as these metabolic derangements occur in 5.9-8.8% of ESRD stroke patients and may complicate clinical assessment 4
- Recognize that ESRD patients have longer hospital stays (mean 29.8 days vs 12.7 days) compared to patients with normal renal function, though ultimate outcomes are comparable if managed appropriately 5
Long-term Considerations
- ESRD patients have 4.1-9.7 times higher risk of hemorrhagic stroke compared to the general population after adjustment for age, gender, and race, with Caucasian females at highest relative risk 6
- The period of dialysis initiation carries particularly high stroke risk, requiring heightened vigilance during this transition 1
