Abstract: El objetivo de este trabajo es evaluar los flujos y resistencias al usar dos tipos de bioconectores luer-lock para catéteres de hemodiálisis. Como objetivos secundarios se pretende evaluar los cambios en la coagulación del sistema, el tiempo empleado en la conexión/desconexión y la opinión de enfermería respecto a su utilización. Material y métodos: estudio experimental aleatorizado en 10 pacientes en hemodiálisis, 5 con bioconector Tego (grupo A) y 5 con BD QSyte (grupo B), a lo largo de 12 sesiones consecutivas (6 con bioconectores y 6 con conexión directa al monitor). Se estudian las siguientes variables: sociodemográficas, tipo de técnica de hemodiálisis, flujos de sangre, presión venosa, Kt, KtV, coagulación del sistema, tiempo empleado en la conexión/desconexión y la opinión del personal de enfermería. Resultados: La muestra se compuso de 6 mujeres y 4 hombres, con una edad media 62 a os y un tiempo medio en hemodiálisis de 4,2 a os. En el grupo A, no existieron diferencias estadísticamente significativas entre los flujos de sangre, las presiones venosas y las dosis de diálisis. El grupo B presentó diferencias estadísticamente significativas en los flujos de sangre y en las presiones venosas. No hubo diferencias entre el uso de bioconectores y la conexión directa al catéter en la coagulación del sistema. Los tiempos de conexión y desconexión disminuyeron en ambos grupos. El personal de enfermería opinó que la comodidad en el uso de bioconectores era: mucha (82%), bastante (9%) e igual que sin ellos (9%). Conclusiones: Las tiempos de conexión y desconexión disminuyen con la utilización de bioconectores. El bioconector Tego , ofrece mejores flujos sanguíneos y menores resistencias venosas. The aim of this study is to evaluate flows and resistances when using two types of luer lock bioconnectors for haemodialysis catheters. As secondary objectives, the study seeks to evaluate the changes in the coagulation of the system, connection/disconnection time and the opinion of nursing staff on their use. Material and methods: randomized experimental study of 10 patients undergoing haemodialysis, 5 with Tego bioconnectors (group A) and 5 with BD Q-Syte (group B), over 12 consecutive sessions (6 with bioconnectors and 6 directly connected to the monitor). The following variables were studied: sociodemographic, type of haemodialysis technique, blood flows, venous blood pressure, Kt, KtV, coagulation of the system, time used in connecting/ disconnecting and the opinion of nursing staff. Results: The sample comprised 6 women and 4 men, with an average age of

Abstract: Objetivo: Comparar la tasa de bacteriemias relacionadas con el catéter de hemodiálisis entre el uso de bioconectores y la conexión directa. Metodología: Estudio retrospectivo comparativo transversal durante un periodo de 2 a os consecutivos (1 a o con conexión directa - Febrero 2009 a Febrero 2010- y 1 a o utilizando bioconectores Tego -Marzo 2010 a Marzo de 2011- ) en los pacientes en hemodiálisis de nuestra unidad que portaban un catéter como acceso vascular permanente. El protocolo de conexión y desconexión de los catéteres durante el periodo de estudio fue el mismo, a excepción de la solución de desinfección empleada: povidona iodada en la conexión directa y clorhexidina al 2% usando bioconectores. Se definió como bacteriemia relacionada con el catéter la aparición de fiebre junto con un hemocultivo positivo, en ausencia de otro foco de infección. Resultados: Se estudiaron 69 pacientes: 36 durante el periodo de conexión directa y 33 durante el periodo del uso de bioconectores. Seis pacientes fueron estudiados durante ambos periodos. La tasa de bacteriemia durante el periodo de conexión directa fue de 24,6 bacteriemias/1000 catéteres-día (9 bacteriemias), mientras que durante el periodo de uso de bioconectores fue de 5,47 bacteriemias/1000 catéteres-día (2 bacteriemias), (p= 0,036). El microorganismo causal más común durante el periodo de conexión directa fue el Staphyloccocus aureus (3 pacientes) junto con el Staphyloccocus coagulasa negativo (3 pacientes). Conclusiones: El uso de bioconectores disminuye de forma significativa la tasa de bacteriemias relacionadas con el catéter de hemodiálisis frente a la conexión directa. Objective: To compare hemodialysis catheter-related bacteremia rate between bioconectors use and direct connection. Methodology: Comparative, retrospective and cross-sectional study over 2 consecutive years (one year with direct connection - 2009 February to 2010 February - and 1 year using bioconectors Tego -2010 March to 2011 March-) in hemodialysis patients in our unit with a permanent catheter as vascular access. Catheters connection and disconnection protocol was the same during the study period, except for the disinfecting solution used: iodine povidone was using in direct connection, and 2% chlorhexidine was using with bioconectors. Catheter-related bacteremia was defined as onset of fever with a positive blood culture in the absence of another infection source. Results: 69 patients were studied: 36 during direct connection period and 33 during use bioconectors period. Six patients were studied during both periods. Bacter

Revista internacional de contaminación ambiental , 2009,
Abstract: Los mantos subterráneos constituyen una de las principales fuentes de abastecimiento de agua potable en México. Por lo general, albergan sólo a ciertos organismos debido a su bajo contenido en materias nutritivas. Sin embargo, las actividades humanas y el crecimiento urbano son los principales factores para la contaminación de los acuíferos. De esta forma, el agua puede contener contaminantes químicos o biológicos que causan diversas enfermedades, entre los que están algunas amibas de vida libre (AVL). El objetivo de este estudio es determinar la calidad microbiológica (coliformes totales, coliformes fecales y amibas de vida libre) del acuífero de Zacatepec, Morelos. Para ello se realizaron muestreos mensuales durante un a o en trece pozos del acuífero; se midieron en el lugar los siguientes parámetros fisicoquímicos: pH, oxígeno disuelto y temperatura. Se determinaron los coliformes totales y fecales utilizando la técnica de filtro de membrana; para las amibas se utilizó el medio selectivo agar no nutritivo con Enterobacter aerogenes (NNE) y la identificación se realizó tomando en cuenta sus características morfológicas. Todos los pozos presentaron contaminación por coliformes totales, uno de ellos con una media geométrica de 107 UFC/100 mL. En cambio, los coliformes fecales estuvieron ausentes en cuatro de los pozos, pero en uno se presentó contaminación alta con una media geométrica de 107 UFC/100 mL. El pozo más contaminado con bacterias fue el número 3 y la contaminación de coliformes totales y fecales más alta se presentó en los meses de abril y julio. Se detectaron amibas de vida libre en todos los pozos; en el 2 se encontró el mayor número de aislamientos amibianos, en tanto que en los pozos 4, 5 y 10 se presentaron los más bajos. Se observaron los números más altos en diciembre y enero y el más bajo en abril. Se aislaron 22 especies pertenecientes a 16 géneros; el más frecuente fue Hartmannella con 38 %, el cual no ha sido reportado como patógeno, pero se ha encontrado asociado a infecciones oculares y cerebrales en humanos. De las amibas patógenas, se detectó Acanthamoeba, pero con baja frecuencia (6.7 %). Los parámetros fisicoquímicos tuvieron muy poca variación temporal: el pH se mantuvo cercano a la neutralidad en un intervalo promedio de 6.7 a 7.3, la temperatura fue de 25.1 a 28.0 °C y el oxígeno disuelto de 2.9 a 4.8 mg/L. Los valores promedio de estos parámetros entre los pozos fueron muy semejantes. La presencia de las bacterias coliformes indica que existe una contaminación de origen antrópico en el acuífero y junto con la presencia d
