In The Medical Field, What Are The Specific Differences Between Latex-coated Gloves And Nitrile-coated Gloves in Terms Of Protective Performance And Allergy Risk?

In the medical field, latex-coated gloves and nitrile-coated gloves differ in the following specific ways in terms of protective performance and allergy risk:

Protective Performance:
Latex-coated gloves are known for their excellent elasticity, allowing a snug fit that provides healthcare workers with outstanding tactile sensitivity and operational flexibility. This makes them especially suitable for tasks requiring fine motor skills, such as surgery and injections. However, latex gloves are relatively weak in chemical resistance and can be degraded by oils and organic solvents, which may compromise their protective effectiveness.

In contrast, nitrile-coated gloves are made from nitrile rubber and offer superior chemical resistance. They effectively block acids, alkalis, organic solvents, and microorganisms, providing more comprehensive protection. Therefore, nitrile gloves have a broader application in medical settings, not only suitable for surgery and cleaning tasks but also commonly used in laboratory operations where high-level protection is required.

Allergy Risk:
The primary allergens in latex-coated gloves are natural latex proteins and chemicals added during manufacturing, such as vulcanizing agents and antioxidants. These substances can cause type I immediate hypersensitivity reactions in healthcare workers, such as urticaria and asthma, as well as type IV delayed hypersensitivity reactions, such as contact dermatitis. Studies indicate that the latex glove allergy rate among healthcare workers ranges from approximately 0.6% to 17%, with higher prevalence in regions of extensive latex glove use.

Nitrile-coated gloves, on the other hand, contain no latex proteins and are typically powder-free, significantly reducing exposure to chemical additives. This effectively eliminates the risk of type I hypersensitivity reactions. Research shows that the incidence of contact dermatitis in nitrile glove users is only about 1.2%, markedly lower than the 7.8% reported for latex glove users.
