Soporte mecánico con membrana de oxigenación extracorpórea veno-arterial (ECMO-VA): evolución a corto y a largo plazo tras la retirada de la asistencia / Mechanical support with venoarterial extracorporeal membrane oxygenation (ECMO-VA): Short-term and long-term prognosis after a successful weaning

Objetivo: La membrana de oxigenación extracorpórea (ECMO) es un tipo de asistencia circulatoria que asocia elevada mortalidad. Sin embargo, superar la fase inicial de soporte mecánico no implica supervivencia ni a corto ni a largo plazo. Objetivo: describir las características y evolución de los pacientes con shock cardiogénico refractario (SCR) asistidos con ECMO veno-arterial (ECMO-VA) en un hospital con programa de trasplante cardíaco. Diseño: Estudio de cohortes y retrospectivo de centro único. Ámbito: UCI cardiológica de un hospital terciario. Pacientes: Un total de 46 pacientes asistidos consecutivamente con una ECMO-VA durante 6 años. Intervenciones: Análisis de la mortalidad hospitalaria tras la retirada del soporte mecánico, de la supervivencia global (SG) y de los factores asociados. Resultados: Quince pacientes (33%) fallecieron con la ECMO-VA y 31 (67%) sobrevivieron a su retirada tras un soporte de 8 días (RIC: 5-15); 14 pacientes fueron trasplantados. La mortalidad hospitalaria en estos pacientes fue del 32% (10/31) y se relacionó con: edad (p=0,001), SAPS-II (p=0,009), sangrado de cánulas (p=0,01), indicación de SCR post-IAM (p=0,001). Con una mediana de seguimiento de 27 meses (RIC: 11-49), seguían vivos el 91% de los pacientes que fueron dados de alta del hospital. La SG tras la retirada de la ECMO-VA se relacionó con el tipo de indicación (p=0,002), teniendo peor pronóstico los pacientes con SCR postinfarto. Conclusiones: En nuestra experiencia, la ECMO-VA es un tipo de asistencia mecánica que puede utilizarse en el manejo del SCR. Asocia una mortalidad precoz elevada, pero tras superar la fase hospitalaria la supervivencia de los pacientes es buena (AU)

Objective: Extracorporeal membrane oxygenation (ECMO) affords mechanical circulatory assistance associated to high mortality. However, weaning from such mechanical support may not imply improved short- or long-term survival. This study describes the characteristics and evolution of patients with refractory cardiogenic shock (RCS) subjected to venoarterial ECMO (VA-ECMO) in a hospital with a heart transplant program. Design: A single-center, retrospective cohort study was carried out. Setting: The cardiovascular ICU of a tertiary hospital. Patients: Forty-six patients consecutively subjected to VA-ECMO over 6 years. Interventions: Hospital mortality after weaning from ECMO and overall survival (OS) were analyzed. Results: Fifteen patients (33%) died with VA-ECMO and 31 (67%) were weaned after 8 days of support (IQR: 5-15). Fourteen patients under went transplantation. Hospital mortality in these patients was 32% (10/31), and was associated to age (P=.001), SAPS II score (P=.009), cannulation bleeding (P=.01) and post-acute myocardial infarction RCS (P=.001). After a median follow-up of 27 months (IQR: 11-49), 91% of the patients discharged from hospital were still alive. Overall survival after weaning from assistance was associated to the type of cardiac disease (P=.002). Patients with RCS after acute myocardial infarction had a poorer prognosis. Conclusions: In our experience, VA-ECMO can be used as mechanical assistance in the management of RCS. The technique is associated to high early mortality, though the long-term survival rate after hospital discharge is good (AU)

Impact on patient outcome of emergency department length of stay prior to ICU admission / Impacto pronóstico de la duración de la estancia en el Servicio de Urgencias antes del ingreso en la UCI

OBJECTIVE: The favorable evolution of critically ill patients is often dependent on time-sensitive care intervention. The timing of transfer to the intensive care unit (ICU) therefore may be an important determinant of outcomes in critically ill patients. The aim of this study was to analyze the impact upon patient outcome of the length of stay in the Emergency Care Department. DESIGN: A single-center ambispective cohort study was carried out. SETTING: A general ICU and Emergency Care Department (ED) of a single University Hospital. PATIENTS: We included 269 patients consecutively transferred to the ICU from the ED over an 18-month period. INTERVENTIONS: Patients were first grouped into different cohorts based on ED length of stay (LOS), and were then divided into two groups: (a) ED LOS ≤5h and (b) ED LOS >5h. VARIABLES: Demographic, diagnostic, length of stay and mortality data were compared among the groups. RESULTS: Median ED LOS was 277min (IQR 129-622). Patients who developed ICU complications had a longer ED LOS compared to those who did not (349min vs. 209min, p < 0.01). A total of 129 patients (48%) had ED LOS >5h. The odds ratio of dying for patients with ED LOS >5h was 2.5 (95% CI 1.3-4.7). Age and sepsis diagnosis were the risk factors associated to prolongation of ED length of stay. CONCLUSIONS: A prolonged ED stay prior to ICU admission is related to the development of time-dependent complications and increased mortality. These findings suggest possible benefit from earlier ICU transfer and the prompt initiation of organ support

OBJETIVO: La evolución de los pacientes críticos se relaciona con intervenciones que dependen del tiempo. Por tanto, el momento de traslado de los pacientes graves a la UCI puede relacionarse con el pronóstico. El objetivo de este estudio fue analizar el impacto de la duración del ingreso en Urgencias sobre el pronóstico de los pacientes. DISEÑO: Estudio de cohortes ambispectivo de centro único. Ámbito: UCI polivalente y Servicio de Urgencias de un Hospital Universitario. PACIENTES: Un total de 269 pacientes ingresados en la UCI consecutivamente desde urgencias durante 18meses. INTERVENCIONES: Se agrupó a los pacientes en cohortes según la duración del ingreso en urgencias. Después se dividieron en 2 grupos: a)estancia en urgencias ≤5h, y b)estancia en urgencias >5h. VARIABLES: Demográficas, diagnóstico, estancia, mortalidad. RESULTADOS: Mediana de estancia en urgencias de 277min (RIC129-622). Los pacientes que desarrollaron complicaciones en la UCI tuvieron mayor estancia en Urgencias que aquellos sin complicaciones (349 vs. 209min, p < 0,01). Un total de 129 pacientes (48%) tuvieron un ingreso en urgencias >5h. La odds ratio para el fallecimiento hospitalario de los pacientes con un ingreso en urgencias >5h fue de 2,5 (IC del 95%, 1,3 a 4,7). La edad y la sepsis fueron los factores de riesgo asociados a la prolongación del ingreso en urgencias. Conclusiones Una estancia prolongada urgencias antes del ingreso en la UCI se relaciona con el desarrollo de complicaciones que dependen del tiempo y con la mortalidad. Estos hallazgos sugieren un beneficio del ingreso precoz en la UCI y del inicio de soporte orgánico sin retraso
