Empleo de ECMO en UCI. Recomendaciones de la Sociedad Española de Medicina Intensiva Crítica y Unidades Coronarias / The use of ECMO in ICU. Recommendations of the Spanish Society of Critical Care Medicine and Coronary Units

El empleo de sistemas de oxigenación con membrana extracorpórea se ha incrementado significativamente en los últimos años; ante esta realidad, la Sociedad Española de Medicina Intensiva Crítica y Unidades Coronarias (SEMICYUC) ha decidido elaborar una serie de recomendaciones que sirvan de marco para el empleo de esta técnica en las Unidades de Cuidados intensivos. Los tres ámbitos de empleo de oxigenación con membrana extracorpórea más frecuentes en nuestro medio son: como soporte cardiocirculatorio, como soporte respiratorio y para el mantenimiento de los órganos abdominales en donantes. La SEMICYUC nombró una serie de expertos pertenecientes a los tres grupos de trabajo implicados (Cuidados Intensivos Cardiológicos y RCP, Insuficiencia Respiratoria Aguda y Grupo de trabajo de Trasplantes de SEMICYUC) que tras la revisión de la literatura existente hasta marzo de 2018, elaboraron una serie de recomendaciones. Estas recomendaciones fueron expuestas en la web de la SEMICYUC para recibir las sugerencias de los intensivistas y finalmente fueron aprobadas por el Comité Científico de la Sociedad. Las recomendaciones, en base al conocimiento actual, versan sobre qué pacientes pueden ser candidatos a la técnica, cuándo iniciarla y las condiciones de infraestructura necesarias de los centros hospitalarios o en su caso, las condiciones para el traslado a centros con experiencia. Aunque desde un punto de vista fisiopatólogico, existen claros argumentos para el empleo de oxigenación con membrana extracorpórea, la evidencia científica actual es débil por lo que es necesario estudios que definen con más precisión qué pacientes se benefician más de la técnica y en qué momento deben iniciarse

The use of extracorporeal membrane oxygenation systems has increased significantly in recent years; given this reality, the Spanish Society of Critical Intensive Care Medicine and Coronary Units (SEMICYUC) has decided to draw up a series of recommendations that serve as a framework for the use of this technique in intensive care units. The three most frequent areas of extracorporeal membrane oxygenation systems use in our setting are: as a cardiocirculatory support, as a respiratory support and for the maintenance of the abdominal organs in donors. The SEMICYUC appointed a series of experts belonging to the three working groups involved (Cardiological Intensive Care and CPR, Acute Respiratory Failure and Transplant work group) that, after reviewing the existing literature until March 2018, developed a series of recommendations. These recommendations were posted on the SEMICYUC website to receive suggestions from the intensivists and finally approved by the Scientific Committee of the Society. The recommendations, based on current knowledge, are about which patients may be candidates for the technique, when to start it and the necessary infrastructure conditions of the hospital centers or, the conditions for transfer to centers with experience. Although from a physiopathological point of view, there are clear arguments for the use of extracorporeal membrane oxygenation systems, the current scientific evidence is weak, so studies are needed that define more precisely which patients benefit most from the technique and when they should start

Guidelines for specialized nutritional and metabolic support in the critically-ill patient. Update. Consensus SEMICYUC-SENPE: Hyperglycemia and diabetes mellitus / Recomendaciones para el soporte nutricional y metabólico especializado del paciente crítico. Actualización. Consenso SEMICYUC-SENPE: Hiperglucemia y diabetes mellitus

Hyperglycemia is one of the main metabolic disturbances in critically-ill patients and is associated within creased morbidity and mortality. Consequently, blood glucose levels must be safely and effectively controlled, that is, maintained within a normal range, avoiding hypoglycemia on the one hand and elevated glucose concentrations on the other. To accomplish this aim, insulin is often required, avoiding protocols designed to achieve tight glycemic control.To prevent hyperglycemia and its associated complications, energy intake should be adjusted to patients’ requirements, avoiding over nutrition and excessive glucose intake. Protein intake should be adjusted to the degree of metabolic stress. Whenever patients require artificial feeding, the enteral route , if not contraindicated, should be used since parenteral nutrition is associated with a higher frequency of hyperglycemia and greater insulin requirements. Enteral nutrition should be administered early, preferably within the first 24 hours of admission to the intensive care unit, after hemodynamic stabilization. Specific diets for hyperglycemia, containing low glycemic index carbohydrates and fibre and enriched with monounsaturated fatty acids, can achieve good glycemic control with lower insulin requirements (AU)

La hiperglucemia es una de las alteraciones metabólicas predominantes en los pacientes críticos y se asocia con un aumento de la morbimortalidad. por ello, es necesario realizar un control efectivo y a su vez seguro de la glucemia, esto es, mantener la normoglucemia en un rango que evite el riesgo de desarrollar hipoglucemia, por un lado, y las cifras elevadas de glucemia, por otro. Para conseguirlo, en la mayoría de los casos es necesario el tratamiento con insulina evitando protocolos dirigidos a conseguir cifras estrictas de glucemias. Con el fin de prevenir la hiperglucemia y sus complicaciones asociadas, el aporte energético debe adecuarse al os requerimientos de los pacientes, evitando la sobre nutrición y el aporte excesivo de glucosa. El aporte proteicos e ajustará al nivel de estrés metabólico. Siempre que el enfermo requiera nutrición artificial y no esté contraindicada debe emplearse la vía enteral, ya que la nutrición parenteral se asocia a mayor frecuencia de hiperglucemia y mayores necesidades de insulina. La administración de la nutrición enteral debe ser precoz, preferiblemente dentro de las primeras 24 h de ingreso en UCI, tras la estabilización hemodinámica. Las dietas específicas para hiperglucemia que contienen hidratos de carbono de bajo índice glucémico, fibra y ricas en ácidos grasos monoinsaturados podrían conseguir un mejor control glucémico con menores necesidades de insulina (AU)

Consensus of the Spanish Society of Intensive Care Medicine and Coronary Units-Spanish Society of Parenteral and Enteral Nutrition (SEMICYUC-SENPE): Respiratory failure

La insuficiencia respiratoria aguda grave que precisa ventilación mecánica es una de las causas más frecuentes de ingreso de los pacientes en UCI. Entre las etiologías más frecuentes se encuentran la reagudización de la enfermedad pulmonar obstructiva crónica y la insuficiencia respiratoria aguda con lesión pulmonar aguda o con criterios de síndrome de distrés respiratorio agudo. Estos pacientes presentan un riesgo elevado de desnutrición por su enfermedad de base, por la situación catabólica en la que se encuentran y por el empleo de la ventilación mecánica. Ello justifica que estos pacientes deban ser valorados desde el punto de vista nutricional y que el uso de soporte nutricional especializado sea necesario. El soporte nutricional especializado debe paliar los efectos catabólicos de la enfermedad, evitar la sobrecarga de calorías y utilizar, en casos seleccionados, dietas específicas enriquecidas con ácidos grasos w-3 y antioxidantes que podrían mejorar el pronóstico (AU)

Severe acute respiratory failure requiring mechanical ventilation is one of the most frequent reasons for admission to the intensive care unit. Among the most frequent causes for admission are exacerbation of chronic obstructive pulmonary disease and acute respiratory failure with acute lung injury (ALI) or with criteria of acute respiratory distress syndrome (ARDS). These patient s have a high risk of malnutrition due to the under lying disease, their altered catabolism and the use of mechanical ventilation. Consequently, nutritional evaluation and the use of specialized nutritional support are required. This support should alleviate the catabolic effects of the disease, avoid calorie overload and, in selected patients, to use omega-3 fatty acid- and antioxidant-enriched diets, which could improve outcome (AU)

[Recommendations for nutritional assessment and specialized nutritional support of critically ill patients]. / Recomendaciones para la valoración nutricional y el soporte nutricional especializado de los pacientes críticos.

Due to the characteristics of critically ill patients, elaborating recommendations on nutritional support for these patients is difficult. Usually the time of onset of nutritional support or its features are not well established, so that its application is based on experts' opinion. In the present document, recommendations formulated by the Metabolism and Nutrition Working Group of the Spanish Society of Intensive and Critical Medicine and Coronary Units (SEMICYUC) are presented. Recommendations are based on the literature analysis and further discussion by the working group members in order to define, consensually, the more relevant issues of metabolic and nutritional support of patients in a critical condition. Several clinical situations have been considered which are developed in the following articles of this publication. The present recommendations aim at providing a guideline for the less experienced clinicians when considering the metabolic and nutritional issues of critically ill patients.

[Artificial nutrition in intestinal failure: short bowel syndrome. Inflammatory Bowel Disease]. / Nutrición artificial en la insuficiencia intestinal: síndrome de intestino corto. Enfermedad inflamatoria intestinal.

Large intestinal resection produces a sufficient number of impairments as to require specialized nutritional support. Basic treatment measures, especially during the acute phase after intestinal resection or in the presence of severe complications in patients with short bowel syndrome, include fluid and electrolytes reposition and nutritional support implementation in order to prevent hyponutrition. Enteral nutrition is the main stimulating factor for adaptation of the remaining bowel. However, its application has some difficulties during the acute phase, and thus patients must be frequently treated with parenteral nutrition. The presence of hyponutrition may be also important in patients with intestinal inflammatory disease. Nutritional support is indicated in these cases as the primary treatment modality for the disease, as hyponutrition treatment, or as perioperative treatment in patients needing surgery. In spite of the digestive pathology, there are data to recommend enteral nutrition as the initial method for nutrients provision in patients that need it.

[Nutritional support in burnt patients]. / Nutrición artificial en el paciente quemado.

Thermal injury leads to a hypermetabolic response which magnitude is among the highest that critically ill patients may present. The energetic waste should be measured by indirect calorimetry in burnt patients. When this test is lacking, published calculations to estimate the energetic waste are useful in these patients. Nutritional therapy in burnt patients should be started early and through the enteral route whenever possible. Total caloric intake is higher than that recommended for other critically ill patients, but should not be higher than 200% of basal energetic waste. Also recommended is a higher hyperproteic intake than that suggested for other situations. With regards to the use of nutrient substrates, there are data to recommend the use of pharmaco-nutrients, such as arginine and glutamine, in burnt patients. In order to stimulate wound healing, it is also recommended to administer vitamin A, vitamin C and zinc supplements.
