CONTEXTO: Hemocultura positiva associada a cateter venoso central tem sido estudada em unidades de terapia intensiva (UTI), mas ainda é controverso se o acesso jugular tem maior incidência de complicações infecciosas que o acesso na veia subclávia. OBJETIVO: Comparar índice de infecção entre os acessos na jugular interna e os na veia subclávia em pacientes internados nas enfermarias de cirurgia. MÉTODOS: Estudo prospectivo, descritivo e comparativo com 114 cateteres em 96 pacientes admitidos nas enfermarias de cirurgia de um Hospital Quaternário, tendo como variáveis o local de inserção, número de lumens, tempo de uso, comparando-os com o índice de complicações infecciosas. RESULTADOS: O índice de infecção foi de 9,64% (11 cateteres), sem significância estatística quando comparados o número de lumens (mono versus duplo) e infecção (p=0,274); também sem significância estatística a comparação entre o tempo de uso (>14 dias) e infecção (p=0,156). Comparando os acessos jugular e subclávia, encontramos significância estatística tendo infecção em 17,2% na subclávia e 1,8% na jugular, com p=0,005. Índice de Hemocultura positivo associado a cateter venoso central foi maior no acesso subclávia quando comparado com jugular interna, com OR 11,2, IC95% (1,4-90,9; p=0,023). CONCLUSÕES: O acesso venoso central na jugular interna tem menor risco de infecção se comparado com subclávia em enfermarias.
Background This study analyzed and described factors related to necrotizing or non-necrotizing soft tissue infections (SSTIs) in a hospitalized patient population in Northeastern South America. Materials and methods This retrospective study included patients hospitalized with SSTIs between January 2011 and December 2016. The main factors related to necrotizing SSTIs (NSTIs) or non-necrotizing SSTIs were analyzed together or separately. Results Of 344 SSTI patients (161 [46.8%] non-necrotizing, 183 [53.2%] necrotizing), NSTI patients had a higher incidence of heart disease ( P = 0.0081) and peripheral arterial disease (PAD; p < 0.001), more antibiotic use, and longer hospital stay ( P < 0.001). NSTI was associated with a 9.58, 33.28, 2.34, and 2.27 times higher risk of PAD (confidence interval [CI] 3.69–24.87), amputation (7.97–139), complications (1.45–3.79), and death (1.2–4.26), respectively, than non-necrotizing SSTI. The risk factors associated with amputation were PAD ( P < 0.001) and poor glycemic control during hospitalization ( P = 0.0011). Factors associated with higher mortality were heart disease ( P < 0.001), smoking ( P = 0.0135), PAD ( P = 0.001), chronic renal failure ( P = 0.0039), poor glycemic control ( P = 0.0005), and evolution to limb irreversibility ( P < 0.001). Conclusion Patients with NSTI have greater illness severity, with a greater association with PAD and amputation. Patients with poor glycemic control more frequently underwent amputation and died.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
