Latex allergic reactions can be divided into the following two categories.

1. Irritant contact dermatitis (ICD): Appears shortly after contact, with clear boundaries of skin lesions, often limited to the contact area ^[2]

Latex allergic reaction is an allergic disease. Latex can cause allergic reactions in the human body through contact with human skin and mucous membranes. Perverted

1. Allergic contact dermatitis is common on the back of the hand. Generally, erythema, pruritus, and pustules may appear after 24 to 48 hours after contact with latex.

2. Irritating contact dermatitis is caused by obstruction, mechanical irritation, alkaline gloves or sweating, manifested as the back of the hand

1. Latex-specific IgE test;

2. Patch test A patch test containing phenylenediamine or a patch of latex gloves is used to distinguish between irritating dermatitis and contact dermatitis caused by delayed-type hypersensitivity.

3. Gloves test Wear latex gloves on the patient for 15 to 60 minutes and observe the symptoms at the same time. ^[1]

Have a history of latex allergies, with the typical symptoms of latex allergic reactions, in vitro test latex allergen IgE positive, you can diagnose latex allergic reactions. ^[1]

1. People with a history of allergic contact with latex products (such as latex gloves, condoms, balloons, catheters, drainage tubes, stethoscope cuffs, tourniquets, rubber handles, remote control buttons, etc.) should avoid contact with latex products.

2. People with a history of allergies such as avocado, banana, chestnut, kiwi, potato or tomato (foods that have a cross-reaction with latex) should use latex products with caution.

3. Monitoring of high-risk groups: Examine medical staff and other workers exposed to natural rubber before contacting. Those with a history of latex allergies should avoid contact with latex products and try chemical alternatives. For example, nitrile gloves made by Kimberly-Clark and other manufacturers are completely suitable for medical staff who are allergic to latex, which can avoid the work risk caused by latex allergy. ^[1]

Progress of allergic reactions in latex products

Latex products are widely used in medicine. It is almost ubiquitous in various clinical departments, such as examination or hands: surgical gloves, urinary catheters, nasogastric tubes, various ventilation tubes. Surgical drainage tubes and various diagnostic catheters, sphygmomanometer airbag bags, beam bands, breathing Machine bellows, masks, even infusion leather tubes, infusion bags, medical bottle stoppers, adhesive tapes and more. In the production of latex, sulfur and other additives should be added to improve the elasticity and other properties of natural rubber. It has long been known that latex can cause dermatitis, and the systemic reaction was introduced in 1988. According to Seth-mat, the incidence of reactions among statisticians is 7.5%. Nurses are 5.6%, while patients with long-term exposure (such as retention of urinary catheterization) are up to 34%. There are two types of allergic reactions Latex allergic reactions ¨J: Contact dermatitis is common among medical staff and rubber factory workers (usually wearing rubber gloves with bow I). It is more likely to be induced by wearing gloves when there is eczema on the hands. Char'pin tested latex skin on 248 surgical nurses and found that 10.6% were positive 41% of them are related to eczema. ^[3]
