RESUMEN
El shock cardiogénico (SC) es un síndrome heterogéneo con elevada mortalidad y creciente incidencia. Se trata de una situación en la que existe un desequilibrio entre las necesidades tisulares de oxígeno y la capacidad del sistema cardiovascular para satisfacerlas debido a una disfunción cardiaca aguda. Históricamente, los síndromes coronarios agudos han sido la causa principal de SC; sin embargo, los casos no isquémicos han aumentado en incidencia. Su fisiopatología implica el daño isquémico del miocardio, una respuesta tanto simpática como del sistema renina-angiotensina-aldosterona e inflamatoria, que perpetúan la situación de hipoperfusión tisular conduciendo finalmente a la disfunción multiorgánica. La caracterización de los pacientes con SC mediante una valoración triaxial y la universalización de la escala SCAI ha permitido una estandarización de la estratificación de la gravedad del SC que, sumada a la detección precoz y el enfoque Hub and Spoke, podrían contribuir a mejorar el pronóstico de los pacientes en SC.

Cardiogenic shock (CS) is a heterogeneous syndrome with high mortality and increasing incidence. It is a condition where there is an imbalance between tissue oxygen demands and the cardiovascular system's capacity to meet them due to acute cardiac dysfunction. Historically, acute coronary syndromes have been the primary cause of CS; however, non-ischemic cases have seen a rise in incidence. Its pathophysiology involves myocardial ischemic damage, a sympathetic, reninangiotensinaldosterone system, and inflammatory response, perpetuating the situation of tissue hypoperfusion, ultimately leading to multiorgan dysfunction. Characterizing CS patients through a triaxial assessment and the widespread use of the SCAI scale has allowed standardization of CS severity stratification, which, coupled with early detection and the Hub and Spoke approach, could contribute to improve the prognosis of CS patients.

La ecografía es un instrumento diagnóstico fundamental en el paciente crítico con membrana de oxigenación extracorpórea (ECMO). Con ella podemos hacer una evaluación anatómica y funcional (cardiaca, pulmonar y vascular) para plantear una adecuada configuración; además, guía su implante, ayuda en la monitorización clínica y la detección de complicaciones, facilita su retirada y completa la evaluación postimplante. En los pacientes con ECMO como soporte respiratorio (veno-venosa), la ecografía torácica permite monitorizar la evolución de la enfermedad pulmonar y la ecocardiografía la evaluación de la función biventricular, especialmente la derecha, y el gasto cardiaco para optimizar el transporte de oxígeno. En la ECMO como soporte circulatorio (veno-arterial), la ecocardiografía supone la guía de la monitorización hemodinámica, permite detectar las principales complicaciones y ayuda al destete del dispositivo. En los equipos ECMO, para un adecuado manejo de estos pacientes, debe haber intensivistas entrenados y con conocimientos avanzados sobre esta técnica. (AU)

In patients with ECMO as respiratory support (veno-venous), thoracic ultrasound allows monitoring pulmonary illness evolution and echocardiography the evaluation of biventricular function, especially right ventricle function, and cardiac output to optimize oxygen transport. In ECMO as circulatory support (veno-arterial), echocardiography is the guide of hemodynamic monitoring, allows detecting the most frequent complications and helps the weaning. In ECMO teams, for a proper management of these patients, there must be trained intensivists with advanced knowledge on this technique. (AU)

El uso de la ecografía en las unidades de críticos se ha extendido de forma exponencial en las últimas dos décadas y se ha convertido en una parte esencial de nuestra práctica clínica. La ecografía abdominal es una técnica ampliamente establecida en otras especialidades, pero su uso en cuidados intensivos ha quedado rezagado respecto a otras modalidades de ecografía. Sin embargo, su potencial papel en el diagnóstico y manejo de los pacientes lo convertirá en una herramienta invaluable para los intensivistas. El uso más extendido de la ecografía abdominal a pie de cama es para la valoración de la presencia de líquido libre en el paciente traumático. No obstante, la ecografía abdominal también puede ayudarnos a diagnosticar pacientes con dolor abdominal, hipovolemia o anuria, y puede guiarnos en procedimientos como la paracentesis o el sondaje vesical o gástrico.

The use of ultrasound while caring for critically ill patients has been increasing exponentially in the last two decades and now is an essential component of intensive care practice. Abdominal ultrasound is an established technique in other specialties, but its use in intensive care has lagged behind other ultrasound modalities. However, its potential role in the diagnosis and management of patients will make it an invaluable tool for intensivists. The main use of abdominal ultrasound at the bedside is for free fluid detection in trauma patients. But abdominal ultrasound can also help us diagnose patients with abdominal pain, hypovolemia or anuria, and it can guide us during procedures such as paracentesis or bladder catheter and gastric tube placement.

Pese a los esfuerzos realizados para mejorar la atención al shock cardiogénico (SC), incluyendo el desarrollo de dispositivos de asistencia circulatoria mecánica (ACM), su pronóstico continúa siendo desfavorable. En este contexto surgen iniciativas de código SC, basadas en proporcionar una asistencia rápida y de calidad a estos pacientes. Este documento multidisciplinario trata de justificar la necesidad de implantar el código SC, definiendo su estructura/organización, criterios de activación, flujo de pacientes según nivel asistencial e indicadores de calidad. Sus propósitos concretos son: a) presentar las peculiaridades de esta enfermedad y el aprendizaje del código infarto y de experiencias previas en SC; b) detallar las bases para el abordaje de estos pacientes, la estructura de los equipos, su logística, la elección del tipo de ACM y el momento de su implante, y c) abordar los desafíos para la implantación del código SC, como la singularidad del código SC pediátrico. Urge desarrollar una asistencia protocolizada, multidisciplinaria y centralizada en hospitales con gran volumen y experiencia que permita minimizar la inequidad en el acceso a la ACM y mejorar la supervivencia de estos enfermos. Solo el apoyo institucional y estructural de las distintas administraciones permitirá optimizar la atención al SC (AU)
Despite the efforts made to improve the care of cardiogenic shock (CS) patients, including the development of mechanical circulatory support (MCS), the prognosis of these patients continues to be poor. In this context, CS code initiatives arise, based on providing adequate, rapid, and quality care to these patients. In this multidisciplinary document we try to justify the need to implement the SC code, defining its structure/organization, activation criteria, patient flow according to care level, and quality indicators. Our specific purposes are: a) to present the peculiarities of this condition and the lessons of infarction code and previous experiences in CS; b) to detail the structure of the teams, their logistics and the bases for the management of these patients, the choice of the type of MCS, and the moment of its implantation, and c) to address challenges to SC code implementation, including the uniqueness of the pediatric SC code. There is an urgent need to develop protocolized, multidisciplinary, and centralized care in hospitals with a large volume and experience that will minimize inequity in access to the MCS and improve the survival of these patients. Only institutional and structural support from the different administrations will allow optimizing care for CS (AU)

The objective was to quantify oxidative stress resulting from ischemia during the donation process, using malondialdehyde (MDA) measurement, and its modulation by the administration of melatonin. We designed a triple-blind clinical trial with donors randomized to melatonin or placebo. We collected donors by donation after brain death (DBD) and controlled donation after circulatory death (DCD), the latter maintained by normothermic regional perfusion (NRP). Melatonin or placebo was administered prior to donation or following limitation of therapeutic effort (LTE). Demographic variables and medical history were collected. We also collected serial measurements of MDA, at 60 and 90 min after melatonin or placebo administration. A total of 53 donors were included (32 from DBD and 21 from DCD). In the DBD group, 17 donors received melatonin, and 15 placebo. Eight DCD donors were randomized to melatonin and 13 to placebo. Medical history and cause for LTE were similar between groups. Although MDA values did not differ in the DBD group, statistical differences were observed in DCD donors during the 0-60 min interval: -4.296 (-6.752; -2.336) in the melatonin group and -1.612 (-2.886; -0.7445) in controls. Given the antioxidant effect of melatonin, its use could reduce the production of oxidative stress in controlled DCD.
RESUMEN
OBJECTIVES: Donation effectiveness is one of the most important factors for the sustainability of the donation transplant process. The aim of this study was to characterize and identify hypothetical factors associated with effective donation (at least one organ transplanted) in the Andalusian population. METHOD: Cross-sectional descriptive observational study of a sample of 4144 potential organ donors registered in the Andalusian Information System of Transplant from January 2006 to December 2018. Donors were categorized according to the result of the donation and analyzed depending their effectiveness. RESULTS: The Andalusian donors were mainly men (60%) and were between 55 and 75 years of age (47.6%). The majority died of brain death (87.45%) caused by a cerebrovascular accident (63.5%). They had cardiovascular risk factors such as hypertension (38.3%), diabetes mellitus (14.8%), dyslipidemia (11.1%), smoking (20.4%), and overweight with a median body mass index of 27.1 kg/m2 (IQR, 24.6-29.4). Effective donor rate was 84.5%. Increasing age, diabetes mellitus, increasing body mass index, and the presence of antibodies against hepatitis C virus were hypothetical predictors of an ineffective donation. CONCLUSIONS: In view of our results, we can say that the Andalusian donor population has a high effectiveness rate, presenting hypothetical factors that could allow one to predict the outcome of an effective donation.

BACKGROUND: Heart failure is the leading cause of death in grown-up congenital heart disease patients (GUCH). Although heart transplantation (OHT) remains the gold standard in end-stage heart failure, the ratio of GUCH patients undergoing this procedure remains low. OBJECTIVE: Describe the cohort of GUCH patients undergoing heart transplantation at a third-level hospital. METHODS: A retrospective review of GUCH patients undergoing OHT between 1997 and 2019 was conducted at a single tertiary university hospital. We included different preoperative (demographic and clinical data, cardiac catheterization data from the last routine hemodynamic monitoring) and postoperative variables (complications, survival). RESULTS: Fourteen patients were enrolled. The median age was 25.5 years (range, 20.7-32.2). Eight patients (57.1%) were male. The median preoperative left ventricular ejection fraction was 37% (range, 22.5%-55%). As for preoperative hemodynamic evaluation, the median for the mean arterial pulmonary pressure was 19 mm Hg (range, 12-22.5), for the capillary wedge pressure was 16 mm Hg (range, 13.5-19.5), and for pulmonary vascular resistance was 1.83 Wood units (range, 1-4). After OHT, 6 patients (42.9%) suffered an infection, the most common of which was respiratory (3 out of 6). Four patients (28.6%) needed renal replacement therapy, and 4 patients (28.6%) presented liver failure. Four patients (28.6%) developed graft failure, thus requiring mechanical support with extracorporeal membrane oxygenation during a median of 6 days (range, 1-17.5). Survival rate of patients under extracorporeal membrane oxygenation was 50%, and overall survival rate was 78.6%. CONCLUSION: OHT represents a good option for GUCH patients, with good overall survival rates.

BACKGROUND: Severe right ventricular failure (RVF) has a significant incidence among cardiac transplant patients. It is a serious complication and an independent risk factor for postoperative mortality. In this setting, ventricular assist devices (VADs) must be considered if conservative medical management fails. This study sought to examine our series of patients with early RVF after heart transplantation requiring VAD support. METHOD: We analyzed consecutive, adult heart transplant recipients at a third level intensive care unit who underwent transplantation from January 2011 to March 2019 requiring post-transplant mechanical circulatory support for RVF. Demographic characteristics, clinical data, complications, and survival rates were collected. RESULTS: Ten patients were included. Median age was 50 years (range, 31.7-57). Eight patients (80%) were male. The most frequent indication for heart transplantation was ischemic heart disease (4 patients) followed by dilated cardiomyopathy and congenital heart disease (2 patients). Preoperative pulmonary hypertension was present in 6 patients. Three patients required a VAD before transplant. Whole survival rate was 60%. After heart transplantation, 7 patients required renal replacement therapy, 2 patients suffered a hemorrhagic stroke, and 5 patients needed a tracheostomy for long-term ventilation. CONCLUSION: Patients who develop RVF after transplantation have an increased incidence of complications and high mortality after surgery. VADs could be implanted immediately after heart transplantation in high-risk patients.

OBJECTIVE: Efforts to expand the organ donor pool to meet growing transplant demands remains a top priority, as does maintaining the quality and safety standards of potential recipients. There is a short window of time from organ retrieval to decision making on organ acceptance, based on the available data. Furthermore, the limitations of intraoperative biopsy can often lead to donor or organ refusal due to a suspected tumor, which, if not confirmed in the final biopsy, results in the loss of a transplant opportunity. METHODS: Donor characteristics and organs discarded on suspicion of neoplastic disease at the time of extraction were analyzed in Andalusia between January 2014 and July 2018. The variable analysis included sociodemographic data, type of donor, location of the potential malignancy, histopathologic examination, and discarded organs. RESULTS: A total of 43 cases were identified. The organs of 33 donors (76.7%) were discarded. Kidneys were the most frequent location for a suspected tumor (44%), followed by the liver (21%). In 18 of the 43 cases (42%), the suspected malignancy was not confirmed, and of these, only 3 livers and 1 kidney were implanted. Sixty potentially transplantable organs were discarded, including those that would have been extracted and/or implanted in the absence of a suspected tumor. CONCLUSIONS: These results highlight the need not only to improve the accuracy of intraoperative biopsies but to seek new decision-making strategies for the short interval after organ retrieval. This involves avoiding both extremes of donation contraindications, while maintaining quality and safety standards.

OBJECTIVE: To analyze metabolic differences during normothermic regional perfusion (NRP) between the dissimilar types of donation after circulatory death, uncontrolled (uDCD) and controlled (cDCD), and the evolution of the transplanted kidneys. METHODS: Observational, prospective, cohort study. We included patients from uDCD and cDCD maintained with NRP in 2017. Six consecutive blood gases were collected with determination of pH and lactic acid. Creatinine levels were monitored at 24 hours, 3 months, and 6 months after transplant and the need for renal replacement therapy was evaluated. Descriptive statistical analysis was performed, presenting the qualitative variables as frequencies and percentages, and quantitative as mean ± SD or median (interquartile range [IQR]). We used χ2 testing for bivariate analysis of qualitative variables. RESULTS: We collected 18 donors. Fifteen out of 18 (83.3%) were men with a median of 51 years (IQR, 46-60). Eleven out of 18 (61.1%) were cDCD and 7 out of 18 (38.9%) were uDCD. The blood gas results are illustrated in Table 1. A total of 28 renal transplants were obtained with a median age of 47 years (IQR, 45-57); 83% were male. Ten out of 28 (35.7%) came from uDCD and 18 out of 28 (64.7%) from cDCD. Table 2 shows the monitoring of the creatinine values of the recipients after the transplantation. CONCLUSIONS: There are more metabolic disorders in our series in uDCD organ donation compared with cDCD. The recovery of the renal function of organs from uDCD is slower than that of cDCD, however; the tendency is toward normality.

Objetivo. Evaluar si las escalas pronósticas APACHE II (Acute Physiology and Chronic Health Evaluation II) y SAPS II (Simplified Acute Physiology Score II) son capaces de predecir la evolución a muerte encefálica en pacientes neurocríticos. Pacientes y métodos. Estudio retrospectivo, observacional, realizado en un hospital de tercer nivel. Se incluyó a 508 pacientes mayores de 16 años, ingresados con patología neurocrítica aguda, con estancia en la unidad de cuidados intensivos de al menos 24 horas. Las variables de interés fueron: datos demográficos, factores de riesgo, APACHE II, SAPS II y resultado pronóstico. Resultados. Mediana de edad: 41 años (rango intercuartílico: 25-57). Varones: 76,2%. Motivo de ingreso más frecuente: traumatismo (55,3%). Medianas: escala de coma de Glasgow (GCS), 10 puntos; APACHE II, 13 puntos; SAPS II, 31 puntos; y estancia en cuidados intensivos, cinco días. La mortalidad en la unidad de cuidados intensivos fue de 145 (28,5%). De ellos, 44 (8,7%) evolucionaron a muerte encefálica. El análisis de regresión logística univariante mostró que la GCS, las escalas APACHE II y SAPS II, y los días de estancia en la unidad de cuidados intensivos se comportaron como variables predictoras de evolución a muerte encefálica. Sin embargo, en el análisis multivariante realizado con APACHE II y SAPS II, se evidenció que sólo APACHE II mantiene significación estadística, a pesar de la buena discriminación de ambas escalas. Conclusión. Los coordinadores de trasplantes podrían usar la escala APACHE II como una herramienta para detectar pacientes con riesgo de evolución a muerte encefálica, minimizando la pérdida de potenciales donantes
Aim. To assess the prognostic value of APACHE II and SAPS II scales to predict brain death evolution of neurocritical care patients. Patients and methods. Retrospective observational study performed in a tertiary hospital. Include 508 patients over 16 years old, hospitalized in ICU for at least 24 hours. The variables of interest were: demographic data, risk factors, APACHE II, SAPS II and outcome. Results. Median age: 41 years old (IR: 25-57). Males: 76.2%. Most frequent reason for admission: trauma (55.3%). Medians: Glasgow Coma Scale (GCS), 10 points; APACHE II, 13 points; SAPS II, 31 points; and ICU stay, 5 days. Mortality in the ICU was 28.5% (n = 145) of whom 44 (8.7%) evolved to brain death. Univariate logistic regression analysis showed that GCS, APACHE II and SAPS II scores, as well as ICU stay days behaved as predictors of brain death evolution. However, the multivariate analysis performed including APACHE II and SAPS II scores showed that only APACHE II maintained statistical significance, despite the good discrimination of both scores. Conclusion. Transplant coordinators might use the APACHE II score as a tool to detect patients at risk of progression to brain death, minimizing the loss of potential donors

INTRODUCTION: Our objectives were to describe the incidence, clinical characteristics, and risk factors for Clostridium difficile infection (CDI) in critically ill patients and to determine C. difficile PCR-ribotypes. METHODS: Prospective, observational study in 26 Spanish ICUs. Patients with diarrhea meeting ESCMID criteria for CDI were included. Molecular characterization of isolates was performed using PCR ribotyping. RESULTS: Of 4258 patients admitted to the ICUs, 190 (4.5%) developed diarrhea. Only 16 patients (8.4%) were diagnosed with CDI. Ribotype 078/126 (25.0%) was the most frequently identified. The mortality rate was similar in patients with ICD compared to patients with diarrhea not caused by C. difficile (p=0.115). Chronic renal insufficiency was identified as the only factor independently associated with the development of CDI (OR 5.87, 95% CI 1.24-27.83; p=0.026). CONCLUSIONS: The incidence of CDI in Spanish ICUs is low. Only chronic renal insufficiency was observed to be a risk factor for CDI development.
