Aplicación de la nueva definición Sepsis-3 en una cohorte de pacientes con sepsis grave y shock séptico ingresados en unidad de cuidados intensivos desde el Servicio de Urgencias / Application of the new Sepsis-3 definition in a cohort of patients with severe sepsis and septic shock admitted to Intensive Care Unit from the Emergency Department

Antecedentes y objetivo: Tras la publicación de la nueva definición de sepsis y shock séptico, nuestro objetivo es analizar la evolución de los pacientes que ingresan en UCI por enfermedad infecciosa utilizando la definición clásica y los nuevos criterios. Material y métodos: Subanálisis de un estudio observacional y prospectivo. Incluye a 98 pacientes ingresados en UCI por enfermedad infecciosa desde Urgencias durante 18 meses. Se estudió la evolución clínica en UCI y la mortalidad hospitalaria. Resultados: El 78% de los pacientes tuvieron shock séptico con la definición Sepsis-2 y el 52% con los criterios Sepsis-3. La mortalidad hospitalaria fue del 29 y del 41%, respectivamente. El RR de mortalidad hospitalaria de los pacientes con shock séptico fue 10,3 (IC 95%: 2,8-37,5) respecto a los pacientes sin shock. La probabilidad de supervivencia a los 30 días de los pacientes con sepsis y shock séptico fue del 78 y 68%, respectivamente (long Rank < 0,001). Conclusiones: En nuestra experiencia, la incorporación de la puntuación SOFA y el lactato a la nueva definición puede mejorar la valoración del riesgo de muerte hospitalaria

Incidence, Risk Factors and Outcomes of Early Acute Kidney Injury After Heart Transplantation: An 18-year Experience.

BACKGROUND: Little is known about the incidence of acute kidney injury (AKI), as defined using the Kidney Disease Improving Global Outcome classification, after heart transplantation (HT). Our objective was to evaluate the impact of AKI in a cohort of HT recipients. (Setting: University Hospital.) METHODS: We studied 310 consecutive HT recipients from 1999 to 2017, with AKI being defined according to the Kidney Disease Improving Global Outcome criteria. Risk factors were analyzed by multivariable analyses, and survival by Kaplan-Meier curves and a risk-adjusted Cox proportional hazards regression model. RESULTS: One hundred twenty-five (40.3%) patients developed AKI, with 73 (23.5%), 18 (5.8%), and 34 (11%) patients having AKI stages 1, 2, and 3, respectively. Cardiac tamponade (odds ratio [OR], 16.82; 95% confidence interval [CI], 1.06-138), acute right ventricular failure (OR, 3.54; 95% CI, 1.82-6.88), and major bleeding (OR, 2.46; 95% CI, 1.18-5.1) were the principal risk factors for AKI. Patients with AKI had a greater hospital mortality (3.8% vs 16%, P < 0.05), especially those requiring renal replacement therapy (46.9% vs 5.4%, P = 0.006). Acute kidney injury requiring renal replacement therapy was independently associated with hospital mortality (OR, 11.03; 95% CI, 4.08-29.8). With a median follow-up after hospital discharge of 6.7 years (interquartile range, 2.4-11.6), overall survival at 1, 5, and 10 years was 95.4%, 85.1%, and 75.4% versus 85.2%, 69.8% and 63.5% among patients without AKI and with AKI stages 2 to 3, respectively (P = 0.08). CONCLUSIONS: The onset of AKI after HT is mainly associated with postoperative complications. Only severe AKI stage predicts worse short-term outcome, with this impact appearing to be lost at long-term follow-up.

Utility of SOFA and Δ-SOFA scores for predicting outcome in critically ill patients from the emergency department.

OBJECTIVE: The condition of critically ill patients in the emergency department (ED) varies from moment to moment. The aims of this study are to quantify sequential organ failure assessment (SOFA) and changes in SOFA scores over time and determine its prognostic impact. PATIENTS AND METHODS: This is a prospective observational cohort study. We included 269 patients consecutively admitted to the ICU from the ED over 18 months. The SOFA scores at ED admission (ED-SOFA) and ICU admission (ICU-SOFA) were obtained. Relative changes in SOFA scores were calculated as follows: Δ-SOFA=ICU-SOFA-ED-SOFA. Patients were divided into two groups depending on the Δ-SOFA score: (a) Δ-SOFA=0-1; and (b) Δ-SOFA more than or equal to 2. RESULTS: The median ED-SOFA score was two points (interquartile range: 1-4.5) and the Δ-SOFA score was 2 points (interquartile range: 0-3). The Δ-SOFA score was more powerful (area under the curve: 0.81) than the ED-SOFA score (area under the curve: 0.75) in predicting hospital mortality. Sixteen (6%) patients had a Δ-SOFA score less than 0, 116 (43%) patients had a Δ-SOFA=0-1, and 137 (51%) patients had a Δ-SOFA of at least 2 points. The probability of being alive at hospital discharge was 51 and 86.5% in Δ-SOFA of at least 2 and Δ-SOFA=0-1 groups, respectively (P<0.001). Risk factors for an increase of two or more SOFA points were age, cirrhosis, a diagnosis of sepsis, and a prolonged ED stay. CONCLUSION: SOFA and changes in the SOFA score over time are potentially useful tools for risk stratification when applied to critically ill patients admitted to ICUs from the ED.

Pronóstico a corto y largo plazo de los pacientes críticos ingresados en la Unidad de Cuidados Intensivos desde el Servicio de Urgencias de un hospital terciario / Short- and long-term prognosis of critically-ill patients referred to the ICU from the Emergency Department of a tertiary hospital

Antecedentes y objetivo. Un origen frecuente de los pacientes que ingresan en la UCI es el Servicio de Urgencias. Es necesario analizar el pronóstico a corto plazo de estos pacientes, pero también su evolución tras el alta hospitalaria, puesto que es una preocupación importante de los enfermos. Nuestro objetivo es describir las características epidemiológicas de los pacientes que ingresan en la UCI desde Urgencias y analizar su evolución. Pacientes y método. Estudio de cohortes observacional y prospectivo. Incluye 269 pacientes ingresados consecutivamente en la UCI desde Urgencias durante 18 meses. Los factores asociados a la mortalidad hospitalaria se presentan en odds ratio (OR) y a la mortalidad a largo plazo como hazard ratio (HR). El nivel de significación aceptado fue del 5%. La supervivencia global se analizó mediante curvas de Kaplan-Meier. Resultados. La mortalidad hospitalaria fue del 15%, las complicaciones desarrolladas en la UCI fueron las variables con mayor impacto en la misma: insuficiencia renal aguda (OR 22,7) y distrés respiratorio (OR 51,2). Tras el alta hospitalaria, la mortalidad acumulada a los 12, 24 y 36 meses fue del 6, 11 y 15%, respectivamente. El grado de dependencia funcional (HR 3,7), el cáncer (HR 3,4) y las arritmias (HR 2,4) fueron los factores relacionados con la mortalidad a largo plazo. Conclusiones. El pronóstico a corto plazo de los pacientes que ingresan en la UCI se relaciona con su edad y comorbilidad, pero sobre todo con las características de la enfermedad aguda. Sin embargo, la evolución a largo plazo está más asociada a las características del paciente (AU)

Background and objective. A frequent source of critically-ill patients admitted to the ICU is the Emergency Department. It is essential to analyse the short-term prognosis of these patients, but also their evolution after their discharge from the hospital, since this is one of the major concerns of these patients. The aim of this study is to describe the epidemiological characteristics of patients admitted to the ICU from the Emergency Department and to analyse their outcome. Patients and method. This consisted of an observational prospective cohorts study which included 269 Emergency Department patients consecutively admitted to the ICU over an 18-month period. Factors associated with hospital mortality were presented as an odds ratio (OR) and factors associated with long-term mortality were presented as a hazard ratio (HR). A P-value lower than .05 was accepted as significant. The overall survival was analysed on the basis of the Kaplan-Meier curves. Results. Hospital mortality was 15%, ICU complications where the variables with the greatest impact on short-term mortality: acute renal failure (OR 22.7) and respiratory distress syndrome (OR 51.2). After hospital discharge, the cumulative mortality at 12, 24 and 36 months was 6, 11 and 15%, respectively. The degree of functional dependence (HR 3.7), cancer (HR 3.4) and arrhythmias (HR 2.4) were factors related to long-term mortality. Conclusions. The short-term outcome of ICU patients is related to age and comorbidity, but more significantly to the characteristics of the acute illness. However, the long-term outcome is more closely associated with the patients’ characteristics (AU)

Evaluation of right ventricular function after cardiac surgery: The importance of tricuspid annular plane systolic excursion and right ventricular ejection fraction.

OBJECTIVE: The evaluation of right ventricular systolic function is essential to the hemodynamic management of critically ill cardiac patients. Nevertheless, assessment of right ventricular function remains problematic. We sought to analyze the correlation between tricuspid annular plane systolic excursion (TAPSE) and right ventricular ejection fraction (RVEF) in the assessment of global and regional right ventricular function, respectively. METHODS: This was a prospective study of 61 cardiac surgical patients. TAPSE was measured with transthoracic echocardiography and RVEF was obtained by a thermodilution pulmonary artery catheter. Both measurements were estimated simultaneously during the early postoperative period. Patients with previously identified severe tricuspid insufficiency were excluded from the study to avoid confounding results. RESULTS: The etiologies for cardiac surgery were surgical pulmonary thromboendarterectomy in 19 patients, valve replacement in 17 patients, heart transplant in 13 patients, and coronary artery bypass graft in 9 patients. Mean RVEF and TAPSE were 26.2% ± 9.7% and 11.4 ± 4 mm, respectively. RVEF and TAPSE showed a significant correlation (r = 0.73, P < .001). Weak reverse relationships between TAPSE or RVEF with afterload hemodynamic parameters, mean pulmonary artery pressure, or pulmonary vascular resistance were elucidated. CONCLUSIONS: TAPSE is a robust measure of right ventricular function that correlates with RVEF assessed by pulmonary artery catheter. A noninvasive method such as echocardiography can guide and support invasive monitoring of right ventricular function in cardiac surgical patients.

Enteral Nutrition in Patients Receiving Mechanical Ventilation in a Prone Position.

BACKGROUND: Patients treated with mechanical ventilation in the prone position (PP) could have an increased risk for feeding intolerance. However, the available evidence supporting this hypothesis is limited and contradictory. OBJECTIVE: To examine the feasibility and efficacy of enteral nutrition (EN) support and its associated complications in patients receiving mechanical ventilation in PP. METHODS: Prospective observational study including 34 mechanically ventilated intensive care patients who were turned to the prone position over a 3-year period. End points related to efficacy and safety of EN support were studied. RESULTS: In total, more than 1200 patients were admitted to the intensive care unit over a period of 3 years. Of these, 34 received mechanical ventilation in PP. The mean days under EN were 24.7 ± 12.3. Mean days under EN in the supine position were significantly higher than in PP (21.1 vs 3.6; P < .001), but there were no significant differences in gastric residual volume adjusted per day of EN (126.6 vs 189.2; P = .054) as well as diet volume ratio (94.1% vs 92.8%; P = .21). No significant differences in high gastric residual events per day of EN (0.06 vs 0.09; P = .39), vomiting per day of EN (0.016 vs 0.03; P = .53), or diet regurgitation per day of EN (0 vs 0.04; P = .051) were found. CONCLUSIONS: EN in critically ill patients with severe hypoxemia receiving mechanical ventilation in PP is feasible, safe, and not associated with an increased risk of gastrointestinal complications. Larger studies are needed to confirm these findings.
