Latex versus nonlatex medical examination gloves
American Journal of Infection Control, April 2002
This study determined the effects of glove stress, type of material, and manufacturer on the barrier effectiveness of medical examination gloves. (1) Eleven brands, four materials (ie, nitrile, copolymer, vinyl, latex), and five manufacturers were assessed. Five research assistants, blinded to the type of glove material, tested stressed and unstressed gloves for barrier effectiveness. A total of 5,510 gloves were tested. Unstressed gloves were tested by visual inspection and a water-leak test. Stressed gloves were subjected to a stress protocol that included rubbing each gloved hand with a washcloth in clean water following a specific sequence. The same water-leak test used on the unstressed gloves then was used on the stressed gloves.
Findings. Nitrile gloves had the lowest failure rate (1.3%). Latex gloves had a failure rate of 2.2%, and vinyl and copolymer gloves had the highest failure rate (8.2%). Adjusting for manufacturer and stress, latex examination gloves were three times more likely to fail than nitrile gloves (odds ratio [OR] 12.60; 95% confidence interval [CI], 1.37 to 7.50).
