Résumé:
During the mid-1980´s, due to the emergence of AIDS, the Centers for Disease
Control and Prevention (CDC) introduction the "Universal Precautions" and
gloves began to be widely used in health services. The use of gloves was
popularize in medical and surgical procedures, and reports of allergic reactions
induced by latex began to emerge. Since then, companies have developed
synthetic substitutes for latex, such as PVC. In 2011, was published the
Resolution RDC nº 55 which established the minimum requirements of identity
and quality for surgical and exam gloves made of natural rubber, synthetic
rubber, a mixture of natural and synthetic rubbers and polyvinyl chloride. Thus,
this study proposes the characterization and evaluation of exam vinvyl gloves,
in order to check if the gloves meet the requirements of the standard ABNT
NBR ISO 11193-2. Three different brands of regularized exam gloves at
ANVISA were evaluated, being characterized by XRD, FTIR, SEM, EDS,
Wetting Test, as well as evaluated the size, impermeability, and tensile
properties according to the standard methodology. It was observed similar
quantities of chemical groups in all samples analyzed by FTIR. The SEM
morphology showed a smooth flat surface of the gloves D and E, while the S
glove presented textured and uniform surface. It was shown that samples of
vinyl gloves tested did not meet the standard´s mechanical requirements,
especially the breaking elongation´s requirement of 350%. A conformity
assessment with a larger sample of vinyl gloves it is suggested, as well as a
further review of the Resolution RDC 55/2011 to assess the need for inclusion
of vinyl gloves in the scope of mandatory certification.
