Infecciones necrosantes de partes blandas atendidas en un servicio de urgencias de tercer nivel: evolución y correlación con la escala laboratory risk indicator for necrotizing fasciitis (LRINEC)

2017 
espanolObjetivo Describir la mortalidad y las complicaciones de pacientes atendidos en urgencias, con diagnostico de infeccion necrosante de partes blandas (INPB) y su correlacion con la escala Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC). Metodo Estudio observacional retrospectivo con inclusion de pacientes con diagnostico de INPB en urgencias de un hospital terciario durante 7 anos. Los resultados se muestran como mediana, rango intercuartilico y rango absoluto para las variables cuantitativas. En el caso de las variables cualitativas, como frecuencias absoluta y relativa. La comparacion se ha llevado a cabo mediante comparacion post-hoc a partir de un analisis ANOVA con aproximacion no parametrica. Las comparaciones entre grupos de LRINEC en las variables cualitativas se han realizado con la prueba exacta de Fisher. Resultados Se identificaron 24 pacientes con edad media de 51,9 anos. La escala LRINEC se determino en 21 pacientes: en 10 indico bajo riesgo ( Conclusiones En general no se ha podido constatar un cambio en el pronostico entre los niveles medio y alto de la escala LRINEC. Pero si entre la estancia hospitalaria entre el nivel bajo y el alto, triplicando practicamente la mediana de dias de estancia hospitalaria. EnglishAim To describe mortality and complications of patients seen in the emergency room, diagnosed with necrotizing soft tissue infection (NSTI) and the correlation of such complications with the Laboratory Risk Indicator for Necrotizing fasciitis scale (LRINEC). Methods Retrospective observational study including patients with a diagnosis of NSTI in the emergency room of a tertiary hospital over 7 years. The results are shown as median, interquartile range and absolute range for quantitative variables. In the case of qualitative variables, the results are shown as absolute and relative frequency. The comparison between the categories of the LRINEC scale was performed through a post-hoc comparison from a non-parametric ANOVA analysis. Comparisons between LRINEC groups in the qualitative variables were performed using Fisher's Exact test. Results 24 patients with a mean age of 51.9 years were identified. The LRINEC scale was used on 21 patients: in 10, the value indicated low risk ( Conclusions In general, a change in the prognosis between the medium and high levels of the LRINEC scale could not be recorded, but was recorded in hospital stay between the low and the high level, practically tripling the median of days of hospital stay.
