Balance hídrico y carga de cloro en las primeras 24h de ingreso en UCI y su relación con las terapias de reemplazo renal mediante un estudio multicéntrico, retrospectivo, de casos y controles emparejados por APACHE-II / Fluid balance and chloride load in the first 24h of ICU admission and its relation with renal replacement therapies through a multicentre, retrospective, case-control study paired by APACHE-II

Objetivo. Analizar la asociación entre el balance hídrico durante las primeras 24h de ingreso en UCI y las variables relacionadas con los valores de cloro (carga de cloro, tipo de fluido administrado, hipercloremia), con el empleo de técnicas de reemplazo renal secundarias a insuficiencia renal aguda (IRA-TRR) durante el posterior ingreso en UCI de los enfermos. Pacientes y métodos. Estudio multicéntrico de casos y controles, de base hospitalaria y ámbito nacional, llevado a cabo en 6 UCI. Los casos fueron pacientes mayores de 18 años que desarrollaron una IRA-TRR. Los controles fueron pacientes mayores de 18 años, ingresados en el mismo periodo y centro que los casos, que no desarrollaron IRA-TRR durante su ingreso en UCI. Se realizó emparejamiento por APACHE-II. Se llevó a cabo un análisis de regresión logística no condicional ajustada por edad, sexo, APACHE-II. Las variables de interés principales fueron: balance hídrico, carga de cloro administrada, e IRA-TRR. Resultados. Se han analizado las variables de 310 enfermos. Se evidenció un aumento del 10% en la posibilidad de desarrollar IRA-TRR por cada 500ml de balance hídrico positivo (OR: 1,09 [IC 95%:1,05-1,14]; p<0,001). El estudio de los valores medios de carga administrada no evidenció diferencias entre el grupo de casos y de controles (299,35±254,91 frente a 301,67±234,63; p=0,92). Conclusiones. El balance hídrico en las primeras 24h de ingreso en UCI se relaciona con el desarrollo de IRA-TRR, independientemente de la cloremia (AU)

Objective. To analyse the association between water balance during the first 24h of admission to ICU and the variables related to chloride levels (chloride loading, type of fluid administered, hyperchloraemia), with the development of acute kidney injury renal replacement therapy (AKI-RRT) during patients’ admission to ICU. Patients and methods. Multicentre case-control study. Hospital-based, national, carried out in 6 ICUs. Cases were patients older than 18 years who developed an AKI-RRT. Controls were patients older than 18 years admitted to the same institutions during the study period, who did not develop AKI-RRT during ICU admission. Pairing was done by APACHE-II. An analysis of unconditional logistic regression adjusted for age, sex, APACHE-II and water balance (in evaluating the type of fluid). Results. We analysed the variables of 430 patients: 215 cases and 215 controls. An increase of 10% of the possibility of developing AKI-RRT per 500ml of positive water balance was evident (OR: 1.09 [95% CI: 1.05 to 1.14]; P<.001). The study of mean values of chloride load administered did not show differences between the group of cases and controls (299.35±254.91 vs. 301.67±234.63; P=.92). Conclusions. The water balance in the first 24h of ICU admission relates to the development of IRA-TRR, regardless of chloraemia (AU)

Current practice in continuous renal replacement therapy: An epidemiological multicenter study. / Manejo actual de las terapias continuas de reemplazo renal: Estudio epidemiológico multicéntrico.

OBJECTIVE: The aim of the study is to ascertain the most relevant aspects of the current management of renal replacement therapy (RRT) in critically ill patients, and to analyze renal function recovery and mortality in patients undergoing RRT. METHODS: A non-interventional three-month observational study was made in 2012, with a follow-up period of 90 days, in 21 centers in Catalonia (Spain). Demographic information, severity scores and clinical data were obtained, as well as RRT parameters. INCLUSION CRITERIA: patients aged ≥ 16 years admitted to Intensive Care Units (ICUs) and subjected to RRT. RESULTS: A total of 261 critically ill patients were recruited, of which 35% had renal dysfunction prior to admission. The main reason for starting RRT was oliguria; the most widely used RRT modality was hemodiafiltration; and the median prescribed dose at baseline was 35mL/kg/h. The median time of RRT onset from ICU admission was one day. The mortality rate at 30 and 90 days was 46% and 54%, respectively, and was associated to greater severity scores and a later onset of RRT. At discharge, 85% of the survivors had recovered renal function. CONCLUSIONS: Current practice in RRT in Catalonia abides with the current clinical practice guidelines. Mortality related to RRT is associated to later onset of such therapy. The renal function recovery rate at hospital discharge was 85% among the patients subjected to RRT.

Blood purification in the critically ill patient. Prescription tailored to the indication (including the pediatric patient) / Depuración de la sangre en el enfermo crítico. Prescripción adaptada a la indicación (incluido el paciente pediátrico)

We maintain a dynamic position on extracorporeal blood purification therapies (EBPT). Continuous therapies are of choice in the hemodynamically unstable patient. We recommend their early introduction in the course of the disease, and starting with a dose of 30-35mL/kg/h. Above all, however, daily re-evaluation is required of the hemodynamic and metabolic situation and water balance of our patients in order to allow dynamic dose adjustment. Some data suggest that continuous EBPT can favorably influence the clinical course of our patients, even in the absence of acute kidney injury. The potential usefulness of hemofiltration at doses higher than the conventional doses (continuous ultrafiltration >50mL/kg/h or pulses of at least 4h a day to more than 100dosesmL/kg/h) for achieving blood purification has also been commented. We review the possible indications of this technique, together with the peculiarities of implementing these therapies in children

Creemos que las técnicas de depuración extracorpórea deben seguir un planteamiento dinámico. Las técnicas continuas son de elección en los pacientes hemodinámicamente inestables. Recomendamos un inicio precoz en el curso de la enfermedad y comenzar con una dosis de 30-35ml/kg/h. Pero, sobre todo, deberemos hacer una reevaluación diaria de la situación del paciente (hemodinámica, metabólica y del estado hidroelectrolítico) para ajustar la dosis de forma dinámica. Algunos datos evidencian que las técnicas de depuración extracorpórea continuas pueden influir favorablemente en la evolución del paciente crítico, independientemente de su función renal. Se comenta también la potencial utilidad de usar dosis de depuración superiores a las convencionales (hemofiltración superior a 50ml/kg/h o pulsos de al menos 4h diarias de más de 100ml/kg/h). Revisamos, asimismo, otras posibles indicaciones de las técnicas de depuración extracorpórea, así como las peculiaridades de su aplicación en pediatría

Utilidad del spect en la embolia grasa cerebral / Cerebral fat embolism and spect usefulness

El síndrome de la embolia grasa es una entidad frecuente en las Unidades de Cuidados Intensivos (UCI). En el caso del paciente politraumatizado con afectación neurológica, lo habitual es que la lesión neurológica sea por el propio traumatismo craneal, pero en algunos casos es secundario al síndrome de la embolia grasa, incluso pueden asociarse. Ante todo paciente politraumatizado que presente un deterioro neurológico conviene establecer un diagnóstico precoz.En ocasiones las pruebas neurorradiológicas habituales no muestran alteraciones en este síndrome de la embolia grasa cerebral. Recientemente hemos tenido ocasión de asistir a dos pacientes polifracturados que presentaron una sintomatología compatible con embolismo graso cerebral, siendo la tomografía computarizada (TC) normal en ambos casos. Para corroborar la sospecha diagnóstica se realizó una gammagrafía cerebral tomográfica (SPECT = Photon Single Emission Computed Tomography) que fue claramente demostrativa de lesión cerebral, sugiriendo que es una exploración a tener en cuenta en el diagnóstico y control evolutivo del embolismo graso cerebral.
