Sodium Profiling HD Poster

Presentation · PPTX


What's in the Poster

The poster is a single wide-landscape slide (13.3" × 7.5") laid out in two rows of three panels:

Row 1 — Background & Science

Panel 1 — Intradialytic Hypotension (IDH)
  • Definition: SBP drop ≥ 20 mmHg or MAP drop ≥ 10 mmHg during HD
  • Incidence: 20–30% of sessions
  • Pathophysiology flow: Ultrafiltration → ↓ Intravascular Volume → Slow Plasma Refilling → ↓ Preload → IDH
  • Risk factors listed (high UF rate, low albumin, cardiac dysfunction, autonomic neuropathy, etc.)
Panel 2 — What is Sodium Profiling?
  • Dynamic variation of dialysate Na⁺ during a session (not a fixed constant)
  • Standard: starts 145–155 mmol/L → tapers to 135–138 mmol/L
  • Three pattern types: Linear Decline, Stepwise Decline, Sine/Cyclic wave
Panel 3 — Mechanism (step-by-step)
  1. High early dialysate Na⁺ creates an osmotic gradient between blood and dialysate
  2. ↑ Serum osmolality draws fluid from interstitial and intracellular space into the intravascular compartment
  3. Plasma refilling rate accelerates — maintaining intravascular volume during active UF
  4. Adequate cardiac preload preserved → BP stabilises → IDH prevented
  5. As Na⁺ tapers later in session, osmotic load reduces — limiting net positive Na⁺ balance
Key summary: ↑dNa⁺ → ↑Osmolality → ↑Plasma Refilling → ↑Preload → ↓IDH Risk

Row 2 — Clinical Application

Panel 4 — Clinical Benefits
  • Reduces symptomatic IDH episodes
  • Stabilises relative blood volume (RBV) during UF
  • Increases absolute plasma refill rate vs. fixed-Na⁺ dialysate
  • Stepwise profiling validated in meta-analysis (Dunne, Hemodial Int 2017)
Panel 5 — Cautions & Drawbacks
  • Sodium loading → ↑ thirst → ↑ IDWG → ↑ next-session UF → vicious cycle
  • May aggravate hypertension in volume-overloaded patients
  • Must re-evaluate monthly for signs of Na⁺ overload
  • Target dialytic Na⁺ balance with conductivity monitoring
Panel 6 — Practical Protocol
StepAction
IdentifyIDH-prone patient (>2 episodes/month)
PrescribedNa⁺ 145–150 → taper to 135–138 mmol/L
CombineAdd cool dialysate (35–36°C) for additive effect
MonitorBP q15–30 min; track IDWG, thirst, interdialytic BP
ReviewMonthly; wean profiling if hypertension emerges
⚠ Avoid sodium profiling as a routine fix for IDWG — treat volume overload first.
