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:
π΄ 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
π 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
π£ 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)

Here is your Dialyzer Reaction clinical poster covering all three major reaction types:
What's on the poster:
| Column | Type | Colour |
|---|---|---|
| Left | Type A - Anaphylactic/Anaphylactoid | π΄ Red |
| Middle | Type B - Mild/Complement-mediated | π Orange |
| Right | Pyrogenic Reactions & Prevention | π£ Purple |
Each section includes Cause β Signs & Symptoms β Management in a clear, colour-coded layout suitable for clinical reference or teaching.

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
| Onset | First 5β10 minutes |
| Cause | IgE hypersensitivity to ethylene oxide (ETO); AN69 + ACE inhibitors |
| Symptoms | Pruritus, urticaria, wheezing, dyspnoea, abdominal cramps, hypotension β shock |
| Management | STOP dialysis, DO NOT return blood; Epinephrine + antihistamines + corticosteroids + Oβ + IV saline |
TYPE B β Mild / Complement-Mediated
| Onset | 15β30 minutes |
| Cause | C3a/C5a complement activation; pulmonary leukostasis from cellulosic membranes |
| Symptoms | Chest pain, back pain, dyspnoea, mild nausea - usually self-resolving |
| Management | Continue dialysis; Oβ; analgesics; switch to synthetic high-flux membrane |
Pyrogenic Reaction
| Cause | Endotoxin fragments from contaminated dialysate crossing the membrane |
| Symptoms | Fever, chills, rigors, headache, hypotension |
| Management | IV 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.
