Latex allergy
Also known as Natural rubber latex allergy · NRL allergy · Latex hypersensitivity · Hevea brasiliensis allergy · Rubber allergy
A fellowship approach to natural rubber latex allergy in children: distinguish Type I IgE-mediated allergy (the dangerous form causing contact urticaria to intraoperative anaphylaxis) from Type IV contact dermatitis and irritant dermatitis; identify the high-risk child (spina bifida, multiple surgeries, atopy); explain the Hev b component framework and latex-fruit syndrome cross-reactivity; apply skin-prick, serum IgE and component-resolved diagnostics; manage with strict latex avoidance, latex-safe surgery protocols, and adrenaline where systemic risk exists; and understand the epidemiological decline driven by powder-free low-protein glove primary prevention across ANZ, UK, US and Canada.

Red flags
- Intraoperative cardiovascular collapse 30 to 60 minutes into surgery in a child with spina bifida or multiple surgeries is latex anaphylaxis until proven otherwise
- Any child with spina bifida or a neural tube defect must be managed latex-safe for every procedure until tests clarify
- Generalised urticaria, wheeze, stridor or hypotension within minutes of latex contact is systemic anaphylaxis — give IM adrenaline first, not an antihistamine
- Powdered latex gloves elsewhere in the operating suite can aerosolise latex protein and trigger a reaction even if the patient's own gloves are latex-free
- A positive latex-specific IgE or skin-prick without a reaction history is sensitisation, not clinical allergy — do not over-restrict on testing alone
- Unexplained reactions to banana, kiwi, avocado or chestnut should prompt latex evaluation for latex-fruit syndrome

Overview & Definition
A six-year-old with spina bifida develops generalised urticaria, wheeze and hypotension 40 minutes into an elective orthopaedic procedure. The anaesthetist has given no new drug since induction. That scenario — delayed intraoperative collapse in a high-risk child — is the archetype of latex anaphylaxis, and it is why every spina bifida patient is managed latex-safe until proven otherwise. [12] [17]
Natural rubber latex (NRL) allergy is an immune-mediated hypersensitivity reaction to proteins in the milky sap of the rubber tree Hevea brasiliensis. The term covers three distinct mechanisms, and confusing them is the commonest error in this topic. Type I is IgE-mediated: immediate, mast-cell-driven, and capable of causing urticaria, wheeze, and anaphylaxis. Type IV is T-cell-mediated allergic contact dermatitis, a delayed eczematous reaction to the chemical accelerators (thiurams, carbamates) added during rubber manufacture. Irritant contact dermatitis is non-immune barrier disruption from wet work and friction. [2] [3]
Only Type I is the dangerous form. It can kill a child on the operating table, which is why latex-safe protocols exist. The other two are chronic skin conditions that impair quality of life and barrier function but do not cause immediate life-threatening reactions. Holding that distinction makes the classification, the diagnosis, and the management fall into place. [1] [4]
The epidemiological backdrop shapes everything: latex allergy was epidemic in the late 1980s and 1990s, then fell sharply after healthcare systems switched to powder-free, low-protein gloves. It is now uncommon in low-risk populations but remains a live threat in the spina bifida, surgical, and previously-sensitised child. [9] [11]
