Abstract
Este trabalho teve como objetivo quantificar as Unidades Formadoras de Colônias (ufc) das luvas de látex para procedimentos no início, meio e fim das caixas na situação real (profissional) e controle (pesquisador) de enluvamento; avaliar a carga microbiana das luvas considerando o tempo de exposição ambiental. Trata-se de um estudo comparativo e prospectivo realizado em uma unidade de terapia intensiva de um hospital-escola. A coleta das amostras microbiológicas das luvas foi realizada por meio da digito-pressão. Avaliaram-se microbiologicamente 186 pares de luvas, 93 no grupo controle e 93 na situação real de enluvamento. No grupo controle a média de ufc foi de 4,7 e na situação real de enluvamento 6,2, consequentemente, não houve diferença estatisticamente significante (p=.601). Também, as ufc no inicio, meio e fim das caixas não se observou diferenças significante (p>.05). A cepa Staphylococcus spp. foi a mais freqüente. O tempo de exposição ambiental das luvas de látex não determinou aumento de ufc.
ABSTRACT - The objective of this study was to quantify the colony forming units (cfu) on latex procedure gloves in the beginning, middle, and end of the containers in real (professional) and controlled (researcher) gloving situations; evaluate the microbial load of the gloves, considering the time of exposure in the environment. This comparative prospective study was conducted at an intensive care unit of a teaching hospital. The microbiological data was collected from the gloves using digital-pressure. Microbiological evaluations were performed on 186 pairs of gloves: 93 in the control group and 93 in real gloving situations. In the control group, the average cfu was 4.7 against 6.2 in the real gloving situation. Hence, no statistically significant difference was found (p=.601). In addition, the cfu values of gloves in the beginning, middle and end of the containers also did not show any significant differences (p>.05). The most common strain was Staphylococcus spp. The time of exposure in the environment did not increase the cfu value of the latex gloves.
