Rubbing ethanol and time of use: critical factors compromising latex gloves structure

Abstract Introduction Personal protective equipment is mandatory to protect patients and professionals from diseases, especially in the dental environment. The risk of gloves micro-perforations is imminent when using sharp instruments or cleaning them up during lengthy clinical procedures. Objective...

Summary:Abstract Introduction Personal protective equipment is mandatory to protect patients and professionals from diseases, especially in the dental environment. The risk of gloves micro-perforations is imminent when using sharp instruments or cleaning them up during lengthy clinical procedures. Objective This study evaluated the integrity of sterile and non-sterile gloves before clinical use and clarified whether friction with disinfectant solution modifies surface morphology and integrity. Material and method Samples of gloves from four different brands were divided into two groups: (1) Sterile surgical gloves (n=260) and (2) Non-sterile gloves (n=260). They were scissored and placed in Ostby’s arch so that three solutions - distilled water, ethanol 70°, ethanol 96° - were rubbed with a cotton swab. After 30s, 5, 10, and 15 minutes of solution rubbing, samples were verified by a Scanning Electron Microscope. The pore sizes were measured by Image J software. Result Regardless of the brands, all gloves have been significantly affected by solutions and assessment periods. In general, remarkable changes were evident with ethanol 70° and 96°, and higher pore diameters were observed compared to distilled water. Conclusion Rubbing disinfectant solutions increases gloves’ pores sizes, and time negatively influenced its quality. Resumo Introdução Para proteger pacientes e profissionais de doenças, o uso de equipamentos de proteção individual é obrigatório, principalmente no ambiente odontológico. O risco de microperfurações das luvas é iminente ao usar instrumentos cortantes ou na tentativa de limpar as luvas durante longos procedimentos clínicos. Objetivo Este estudo avaliou a integridade das luvas cirúrgicas e de procedimento antes do uso clínico e esclareceu se o atrito com a solução desinfetante modifica a morfologia e integridade da superfície. Material e método Amostras de luvas de quatro marcas diferentes foram divididas em dois grupos: (1) Luvas cirúrgicas (n = 260) e (2) Luvas descartáveis não estéreis (n = 260). As luvas foram cortadas e colocadas em arco de Ostby, de modo que três soluções - água destilada, etanol 70 °, etanol 96 ° foram esfregadas com um cotonete. Após 30s, 5, 10 e 15 minutos de fricção das soluções, as amostras foram verificadas utilizando um microscópio eletrônico de varredura. Os tamanhos dos poros foram medidos pelo software Image J. Resultado Independentemente das marcas, todas as luvas foram significativamente afetadas por soluções e
