What the poster covers

The poster is a single wide-format landscape slide (13.3 x 7.5 inches) with a dark navy background and three colour-coded columns:

πŸ”΄ TYPE A - Anaphylactic/Anaphylactoid (Red column)

  • Cause: IgE-mediated hypersensitivity to ethylene oxide (ETO) sterilant; complement activation via AN69 membrane; ACE inhibitor + AN69 interaction
  • Onset: Within the first 5-10 minutes
  • Signs & Symptoms: Pruritus, urticaria, angioedema, wheezing, dyspnoea, abdominal cramps, hypotension, anaphylactic shock, cardiac arrest
  • Management: STOP dialysis immediately - DO NOT return blood; Epinephrine, IV antihistamines, IV corticosteroids, Oβ‚‚, IV saline

🟠 TYPE B - Mild/Complement-mediated (Orange column)

  • Cause: C3a/C5a anaphylatoxin generation, pulmonary leukostasis, cytokine release from cellulosic membranes
  • Onset: 15-30 minutes after start
  • Signs & Symptoms: Chest pain, back pain, dyspnoea, nausea, mild hypotension - usually self-resolving
  • Management: Continue dialysis; Oβ‚‚; analgesics; reduce blood flow rate; switch to synthetic high-flux membrane

🟣 Pyrogenic Reactions & Prevention (Purple column)

  • Endotoxin crossing dialyzer from contaminated dialysate
  • Fever, chills, rigors, hypotension
  • Management + comprehensive prevention strategies for all types
  • Drug-induced reactions note (iron dextran, heparin)

Summary

Dialyzer Reactions - Summary

What is a Dialyzer Reaction?

An adverse reaction during haemodialysis caused by the dialyzer membrane, sterilants, or dialysate contamination.

TYPE A β€” Anaphylactic/Anaphylactoid

OnsetFirst 5–10 minutes
CauseIgE hypersensitivity to ethylene oxide (ETO); AN69 + ACE inhibitors
SymptomsPruritus, urticaria, wheezing, dyspnoea, abdominal cramps, hypotension β†’ shock
ManagementSTOP dialysis, DO NOT return blood; Epinephrine + antihistamines + corticosteroids + Oβ‚‚ + IV saline

TYPE B β€” Mild / Complement-Mediated

Onset15–30 minutes
CauseC3a/C5a complement activation; pulmonary leukostasis from cellulosic membranes
SymptomsChest pain, back pain, dyspnoea, mild nausea - usually self-resolving
ManagementContinue dialysis; Oβ‚‚; analgesics; switch to synthetic high-flux membrane

Pyrogenic Reaction

CauseEndotoxin fragments from contaminated dialysate crossing the membrane
SymptomsFever, chills, rigors, headache, hypotension
ManagementIV fluids, stop ultrafiltration, antipyretics, blood cultures if infection suspected

Prevention at a Glance

  • Type A: Rinse dialyzer before use; use gamma/steam sterilization; avoid ETO; avoid AN69 in ACE inhibitor patients
  • Type B: Use synthetic high-flux membranes; reprocess dialyzers; avoid unsubstituted cellulosic membranes
  • Pyrogenic: Ultrapure dialysate water; regular microbial monitoring; proper catheter care
Key rule: Type A = STOP immediately. Type B = can usually continue dialysis.
