Eficácia do uso do álcool etílico 70% na antissépsia da pele antes da coleta de sangue / Efficacy of 70% ethyl alcohol use o9n skin antissepsia before blood collection
Objective To quantify the presence of agents of the microbial flora of the skin of patients in the collection room of a hospital (UBS) as well as to verify the efficacy of skinantisepsis with the use of 70% ethyl alcohol prior to blood collection. Methods The collection of the antecubital region of the arm of the 40 randomly selected patients was performed before and after site antisepsis with 70% ethyl alcohol, with the aid of a swab soaked in sterile solution for subsequent transportation and processing, which was performed in the laboratoryUniversity of São Paulo UNIP, JK campus, São José do Rio Preto. Results From the 80 samples (40 before antisepsis and 40 after antisepsis) collected, a reduction of 87.01% in the number of colonies of microorganisms identified as cocci and gram positive bacilli, catalase positive, was observed. Conclusion The results of the research allow us to conclude that 70% ethyl alcohol is effective in antisepsis of the skin and that antisepsis with 70% ethyl alcohol reduces the microbial flora of the skin giving greater safety and reduced risk to the procedure prior to blood collection
