“…10 Although we found a significantly lower colonization rate of the CCCs citrate compared with the Tego sodium chloride lock system, we could not demonstrate a reduction of CRBSIs. However, our study was not designed to detect CRBSI; data about CRBSI were collected retrospectively, and the CRBSI rate was very low in all 3 groups (overall, 0.21 CRBSIs per 1,000 catheter-days).…”

Thirty-nine hemodialysis patients with permanent central venous catheters were analyzed for bacterial catheter colonization comparing different catheter-lock strategies. The closed needleless Tego connector with sodium chloride lock solution was significantly more frequently colonized with bacteria than the standard catheter caps with antimicrobially active citrate lock solution (odds ratio, 0.22 [95% confidence interval, 0.07-0.71]; P = .011). Infect Control Hosp Epidemiol 2013;34(12):1314-1317Catheter-related bloodstream infection (CRBSI) is a serious complication in patients with tunneled long-term central venous catheters (CVCs) undergoing chronic hemodialysis.

“…In recent years, however, they have been related to important nosocomial infections, mainly in weakened and elderly patients and low-weight infants. (15,16) In addition, some species produce a slime layer of polysaccharides that increases the bacterial adhesion to the different surfaces and is related to the formation of biofilms. (17,18) The susceptibility profile of the Staphylococcus revealed that, of all isolated strains, 61.5% were oxacillin-resistant.…”

Objectives: To identify the presence of contamination on tourniquets for peripheral intravenous puncture and to characterize the profile of the Staphylococcus spp. and the isolated yeasts. Methods: Cross-sectional study in which 18 tourniquets for peripheral intravenous puncture in use at a hospital were analyzed. The tourniquets were immersed in BHI broth for 24h and cultivated in selective media for isolation and identification of Staphylococcus spp. and yeasts. The disk-diffusion method was employed to analyze the susceptibility profile of the Staphylococcus spp. to the antimicrobial agents. Results: The growth of some microorganism was identified on 13 (72.2%) tourniquets: 11 (52.4%) coagulasenegative Staphylococcus, two (9.5%) Staphylococcus aureus, four (19%) Rodothorula mucilaginosa, three (14.3%) Candida albicans. 61.5% of the Staphylococcus spp. were oxacillin-resistant. The team professionals did not mention protocols for cleaning, disinfection or controlled replacement of these materials at the institution. Conclusion: The contamination of tourniquets by pathogenic microorganisms was identified, with a resistance profile to the antibiotics that are frequently used in hospitals. ResumoObjetivos: Identificar a presença de contaminação em torniquetes para punção intravenosa periférica e caracterizar o perfil dos Staphylococcus spp. e leveduras isolados. Métodos: Estudo transversal que inseriu análise de 18 torniquetes para punção intravenosa periférica em uso no hospital. Os torniquetes foram imersos em caldo BHI por 24h e cultivados em meios seletivos para isolamento e identificação de Staphylococcus spp. e leveduras. O método disco-difusão foi empregado para analisar o perfil de suscetibilidade dos Staphylococcus spp. aos antimicrobianos. Resultados: Treze (72,2%) torniquetes apresentaram crescimento de algum micro-organismo sendo 11 (52,4%) Staphylococcus coagulase-negativo, dois (9,5%) Staphylococcus aureus, quatro (19%) Rodothorula mucilaginosa, três (14,3%) Candida albicans. 61,5% dos Staphylococcus spp. apresentaram resistência a oxacilina. Os profissionais da equipe não relataram protocolos para limpeza, desinfecção ou substituição controlada destes materiais na instituição. Conclusão: Foi identificada a contaminação de torniquetes por micro-organismos patogênicos com perfil de resistência aos antibióticos muito utilizados em instituições hospitalares.

Objetivo: identificar evidências científicas presentes nas publicações relacionadas à infecção em cateter venoso central para hemodiálise. Método: revisão integrativa de literatura. A busca foi realizada nas bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Biblioteca Nacional de Medicina dos Estados Unidos (PubMed), no mês de dezembro de 2015. Resultados: os 13 estudos analisados demonstraram altos índices de infecção relacionados a cateter, sendo o Staphylococcus aureus o micro-organismo mais observado. Alguns fatores de risco para infecção citados, relacionados ao paciente, foram hipertensão, diabetes mellitus e hipoalbuminemia. O tempo de uso do cateter esteve entre os fatores de risco para infecção. Conclusão: os resultados apresentam possíveis alternativas que podem auxiliar na prevenção e redução das infecções relacionadas ao cateter.Descritores: Enfermagem Baseada em Evidências; Revisão; Infecções Relacionadas a Cateter. Objective: identify the scientific evidence present in publications related to central venous catheter-related infection in hemodialysis. Method: integrative literature review.

Endoluminal colonization as a risk factor for coagulase-negative staphylococcal catheter-related bloodstream infections in haemodialysis patients

Abstract: This study shows that ECC may predict the risk of developing CRSBI. Surveillance cultures could, therefore, be used to triage individual HD patients who might benefit from specific intervention measures.
