The disinfection procedures aim to reduce the microbial load, but there are doubts about risks of contamination spreading into lumens devices, such as three-way stopcocks (3-WS). This study aimed at an in vitro evaluation antibacterial procedure manual friction 3-WS intentionally contaminated and determine solution dispersion lumens. Laboratory experiments were developed two steps: bacterial spread through intentional with Staphylococcus aureus Pseudomonas aeruginosa, alcohol After saline 0.85% (w/v) [control group], S. P. aeruginosa isolated 55.6% 27.8% respectively. However, after ethyl 70% (w/v), was no 3-WS. On other hand, (dye) evidenced by different techniques: Durham tubes (5.6%) swabs (46.3%). demonstrated efficacy, it refers reflections on risk diffusion venous network inherent clinical practice situations patient safety.
