Use of thoracic fluid content for prediction of fluid balance and postoperative pulmonary complications after major abdominal surgery: an observational study.

BACKGROUND AND OBJECTIVES: The harmful effects of excess fluids frequently manifest in the lungs. Thoracic fluid content (TFC) is a variable provided by the STARLINGTM bioreactance monitor, which represents the total volume of fluid in the chest. The objective is to analyse the association between the variation in TFC values (TFCd0%) at 24 h postoperatively, postoperative fluid balance, and postoperative pulmonary complications. MATERIAL AND METHODS: Prospective and analytical observational study. Patients scheduled for major abdominal surgery at a tertiary teaching hospital were included. They were monitored during the intervention and the first 24 postoperative hours with the monitor. STARLINGTM, measuring TFC and its variation in different stages of the perioperative period. Serial lung ultrasounds were performed and postoperative pulmonary complications were recorded. Logistic regression was performed to predict the occurrence of atelectasis and pulmonary congestion. The Pearson correlation coefficient was calculated to verify the association between TFC and fluid balance. RESULTS: 50 patients were analyzed. TFCd0% measured on the morning of the first postoperative day increased by a median of 27.1% [IQR: 20.3-37.5] and was correlated at r = 0.44 with the postoperative balance of 677 ml [IQR: 125.5-1,412]. Increased TFC was related to a higher risk of atelectasis (OR = 1.24) and pulmonary congestion (OR = 1.3). CONCLUSIONS: TFCd0% measured 24 h after surgery presents a moderate correlation with postoperative fluid balance. Its increase is a risk factor for the appearance of postoperative pulmonary complications.

Uso del contenido de fluido torácico para la predicción del balance hídrico y las complicaciones pulmonares postoperatorias tras cirugía abdominal mayor / Use of thoracic fluid content for prediction of fluid balance and postoperative pulmonary complications after major abdominal surgery: An observational study

Antecedentes y objetivos: Los efectos nocivos del exceso de líquidos se manifiestan frecuentemente en los pulmones. El contenido de fluido torácico (thoracic fluid content [TFC]) es una variable que proporciona el monitor por biorreactancia STARLING™, que representa el volumen total de líquido en el tórax. El objetivo es analizar la asociación entre la variación de los valores del TFC (TFCd0%) a las 24horas postoperatorias, el balance hídrico postoperatorio y las complicaciones pulmonares postoperatorias. Material y métodos: Estudio observacional prospectivo y analítico. Se incluyeron pacientes programados para cirugía abdominal mayor en un hospital universitario de tercer nivel. Fueron monitorizados durante la intervención y las 24 primeras horas postoperatorias con el monitor STARLING™, midiendo el TFC y su variación en distintas etapas del perioperatorio. Se realizaron ecografías pulmonares seriadas y se recogieron las complicaciones pulmonares postoperatorias. Se realizó una regresión logística para predecir la aparición de atelectasias y congestión pulmonar. Se calculó el coeficiente de correlación de Pearson para comprobar la asociación entre TFC y balance hídrico. Resultados: Se analizaron 50 pacientes. El TFCd0% medido en la mañana del primer día postoperatorio aumentó una mediana del 27,1% [IQR: 20,3-37,5] y se correlacionó con una r=0,44 con el balance postoperatorio de 677ml [IQR: 125,5-1.412]. El aumento del TFC se relacionó con un mayor riesgo de sufrir atelectasias (OR=1,24) y congestión pulmonar (OR=1,3). Conclusiones: El TFCd0% medido a las 24horas de la cirugía presenta una correlación moderada con el balance hídrico postoperatorio. Su incremento es un factor de riesgo para la aparición de complicaciones pulmonares postoperatorias.(AU)

Parada cardiorrespiratoria intrahospitalaria: incidencia, factores pronósticos y resultados / In-hospital cardiac arrest: incidence, prognostic factors and results

Introducción y objetivos: La parada cardiorrespiratoria (PCR) intrahospitalaria es una entidad clínica con elevada morbimortalidad que presentan hasta el 2% de los pacientes ingresados. La PCR supone un importante problema de salud pública a nivel económico, social y sanitario, susceptible de revisión y mejora. El objetivo de este estudio es determinar su incidencia, la recuperación de la circulación espontánea (RCE) y la supervivencia en el Hospital de la Princesa, así como las características clínicas y demográficas de los pacientes que la sufren. Material y métodos: Estudio observacional, retrospectivo, descriptivo, de tipo registro de casos, durante un periodo de 12 meses, de pacientes por los que se avisó por PCR al equipo de intervención rápida (EIR) compuesto por el servicio de Anestesiología y Reanimación. Resultados: Un total de 44 pacientes fueron incluidos en el estudio, de los cuales 22 (50%) eran mujeres. La edad media fue de 75,70 años (±15,78 años). La incidencia obtenida fue de 2,88 PCR por cada 100.000 ingresos hospitalarios; 22 (50%) pacientes consiguieron la RCE y 11 (25%) obtuvieron la supervivencia al alta hospitalaria. La comorbilidad más prevalente en los pacientes con PCR fue la hipertensión arterial (63,64%). No fueron presenciadas el 66,7% de las PCR y solo el 15,9% presentaron un ritmo desfibrilable. Conclusiones: Los resultados obtenidos son similares a los presentados en otros grandes estudios. Por esta razón, recomendamos implementar EIR y dedicar tiempo a la formación del personal hospitalario en torno a la PCR.(AU)

Background and aims: In-hospital cardiac arrest (CA) is a clinical entity with high morbidity and mortality that occurs in up to 2% of hospitalized patients. It is a public health problem with important economic, social, and medical repercussions, and as such its incidence needs to be reviewed and improved. The aim of this study was to determine the incidence of in-hospital CA, return of spontaneous circulation (ROSC), and survival rates at Hospital de la Princesa, and to define the clinical and demographic characteristics of patients with in-hospital CA. Material and methods: Retrospective observational chart review of patients presenting in-hospital CA and treated by anaesthesiologists from the hospital's rapid intervention team. Data were collected over 1 year. Results: Forty-four patients were included in the study, of which 22 (50%) were women. Mean age was 75.70 years (±15.78 years), and incidence of in-hospital CA was 2.88 per 100,000 hospital admissions. Twenty-two patients (50%) achieved ROSC and 11 patients (25%) survived until discharge home. The most prevalent comorbidity was arterial hypertension (63.64%); 66.7% of cases were not witnessed, and only 15.9% presented a shockable rhythm. Conclusions: These results are similar to those reported in other larger studies. We recommend introducing immediate intervention teams and devoting time to training hospital staff in in-hospital CA.(AU)

Los equivalentes metabólicos estimados no se relacionan con el consumo máximo de oxígeno calculado en pacientes candidatos a cirugía de resección pulmonar / Estimated metabolic equivalents of task do not correlate with the maximal oxygen consumption of patients undergoing lung resection surgery

Antecedentes y objetivo: Los equivalentes metabólicos (MET) son una medida fisiológica que representa el coste metabólico de una actividad de la vida cotidiana. Un MET equivale al consumo metabólico en reposo. Los MET se pueden estimar mediante cuestionarios o calcular a partir de la medida del máximo consumo de oxígeno (VO2máx). El objetivo de este estudio es determinar si existe concordancia entre los MET estimados en la consulta de preanestesia (METSe) con los MET calculados a partir de VO2máx (METVO2). Pacientes y métodos: Estudio observacional retrospectivo en pacientes candidatos a cirugía de resección pulmonar. La estimación de los METSe se obtuvo en la consulta de preanestesia de acuerdo a las guías europeas y americanas de valoración cardiovascular preoperatoria en cirugía no cardiaca de 2014. El VO2máx se calculó en el laboratorio de ergometría. Resultados: Se incluyeron un total de 104 pacientes en el estudio, de los que 25 (24%) eran mujeres. La edad media fue de 65,1 años (±9,8). Veintiséis pacientes (25%) presentaron una clasificación concordante de METSe con METVO2 (κ=−0,107; p=0,02). En el resto de los pacientes, los METSe sobreestimaron la capacidad funcional medida por ergometría (METSe>METVO2). Conclusiones: La valoración subjetiva sobreestima la capacidad funcional y no debe reemplazar la realización de pruebas objetivas en pacientes propuestos para cirugía de resección pulmonar.(AU)

Background and objective: Metabolic equivalent of task (MET) is a physiological measure that represents the metabolic cost of an activity of daily living. One MET is equivalent to the resting metabolic rate. METs can be estimated by questionnaires or calculated by measuring maximal oxygen uptake (VO2max). The aim of this study is to determine whether METs estimated in the pre- consultation (METse) correlates with METs calculated from VO2max (METsVO2). Patients and methods: Retrospective observational study in patients scheduled for lung resection surgery. The estimation of METs was obtained in the pre- consultation according to the 2014 European and American guidelines for preoperative cardiovascular assessment in non-cardiac surgery. VO2max was calculated in the ergometry laboratory. Results: A total of 104 patients were included in the study, of whom 25 (24%) were female. The mean age was 65.1 years (±9.8). In 26 patients (25%), the METse classification correlated with METsVO2 (κ=−0.107; P=0.02). In the remaining patients, METse overestimated functional capacity measured by ergometry (METse>METsVO2). Conclusions: Subjective assessment overestimates functional capacity and should not replace objective testing in patients scheduled for lung resection surgery.(AU)

Preoperative nutritional status assessed using the CONUT tool and its relationship with the appearance of major postoperative complications.

INTRODUCTION: Malnutrition is a risk factor for the appearance of major postoperative complications; therefore, early identification and perioperative optimization of surgical patients may improve postoperative outcomes. The objective of our study was to determine the prevalence of moderate or high under nutrition alerts in patients undergoing major non-cardiac surgery, and their relationship with the appearance of major postoperative complications. Nutritional status was calculated using the CONUT tool. MATERIAL AND METHODS: A retrospective observational study in 190 patients who underwent major non-cardiac surgery over two consecutive years. Preoperative nutritional status was calculated using CONUT, and the patients' medical records were reviewed to determine their epidemiological characteristics and major complications. RESULTS: The under nutrition alert was moderate in 17% of patients, and high in 10%. A high under nutrition alert was an independent risk factor for treatment with vasoactive drugs (OR 3.58; 95% CI 1.18-10.89; p = 0.025), respiratory support (OR 7.63; 95% CI 1.25-46.43; p = 0.027), renal support (OR 23.29; 95% CI 2.0-271.08; p = 0.012), prolonged hospital stay (Coef 20.16; 95% CI 2.10-38.22; p = 0.029) and higher in-hospital mortality (OR 7.15; 95% CI 1.31-39.02; p = 0.023). CONCLUSIONS: In total, 10% of patients who underwent major non-cardiac surgery presented serious preoperative deterioration in their nutritional status. A high under nutrition alert was an independent risk factor for the appearance of major postoperative complications.

Estado nutricional preoperatorio valorado mediante la herramienta CONUT y su relación con la aparición de complicaciones mayores postoperatorias / Preoperative nutritional status assessed using the CONUT tool and its relationship with the appearance of major postoperative complications

Introducción: La desnutrición es un factor de riesgo para la aparición de complicaciones mayores postoperatorias, por lo que una identificación precoz de los pacientes, acompañada de una optimización perioperatoria, puede relacionarse con una mejoría de los resultados. El objetivo de nuestro estudio fue conocer la prevalencia de alerta nutricional moderada o alta, calculada por el sistema CONUT, en los pacientes intervenidos de cirugía mayor no cardiaca y su relación con la aparición de complicaciones mayores postoperatorias. Material y métodos: Estudio retrospectivo observacional que incluyó 190 pacientes intervenidos de cirugía mayor no cardiaca en el periodo de dos años consecutivos, con alerta nutricional CONUT calculada previa a la intervención. Se revisaron las historias clínicas para conocer las características epidemiológicas de los pacientes así como las complicaciones mayores asociadas. Resultados: La prevalencia de alerta nutricional moderada fue del 17% y alta del 10%. Tener una alerta nutricional alta fue factor de riesgo independiente de necesidad de tratamiento con drogas vasoactivas (OR 3,58; IC 95% 1,18-10,89; p=0,025), terapia de soporte respiratorio (OR 7,63; IC 95% 1,25-46,43; p=0,027), soporte renal (OR 23,29; IC 95% 2,0-271,08; p=0,012), aumento de estancia hospitalaria (coef. 20,16; IC 95% 2,10-38,22; p=0,029) y mayor mortalidad durante el ingreso (OR 7,15; IC 95% 1,31-39,02; p=0,023). Conclusiones: El 10% de los pacientes que se intervinieron de cirugía mayor no cardiaca presentaron un deterioro preoperatorio grave del estado nutricional. Una alerta nutricional alta fue factor de riesgo independiente para la aparición de complicaciones mayores postoperatorias.(AU)

Incidence of electrocardiographic alterations in the preoperative period of non-cardiac surgery.

BACKGROUND: The electrocardiogram is the most widely used test to assess cardiovascular risk during the preoperative period. The objective of the present study is to evaluate the incidence of electrocardiographic alterations in the general population scheduled for non-cardiac surgery and to determine if the age greater than or equal to 65 years or the revised cardiac risk index ≥1 represent a risk factor for presenting these alterations. MATERIAL AND METHODS: Over a period of one month, all preoperative electrocardiograms (ECG) from the anesthesia clinic were analyzed. Various epidemiological data were collected and the revised cardiac risk index was calculated. Major alterations were defined as those requiring Cardiology follow-up. RESULTS: 476 patients were recruited, of whom 40.8% were ≥65 years, 32.6% had HTN, 14.4% DM and 27.9% dyslipidemia. 16.16% of the patients had a Lee Index ≥1. Of the entire sample, 80.5% had a normal ECG, 6.5% minor alterations and 13.0% major alterations. In the multivariate analysis, age ≥65 years and the presence of HTN were shown as independent risk factors for presenting alterations in the total and major ECG. The Lee index ≥1 was not associated with an increased risk of electrocardiographic abnormalities. CONCLUSIONS: Patients ≥65 years old and those with HTN are at greater risk of presenting major electrocardiographic abnormalities, so we recommend including the ECG as a routine diagnostic test in the preoperative period of non-cardiac surgery.

Antecedentes: El electrocardiograma es la prueba más utilizada para evaluar el riesgo cardiovascular durante el periodo preoperatorio. El objetivo del presente estudio es evaluar la incidencia de alteraciones electrocardiográficas en la población general programada para cirugía no cardiaca y determinar si la edad ≥ 65 años o el índice de riesgo cardiaco revisado ≥ 1 suponen un factor de riesgo para presentar dichas alteraciones. Material y métodos: Durante un periodo de un mes se analizaron todos los electrocardiogramas (ECG) preoperatorios de la consulta de anestesia. Se recogieron datos epidemiológicos y se calculó el índice de riesgo cardiaco revisado. Se definieron como alteraciones electrocardiográficas mayores aquellas que precisaban seguimiento por Cardiología. Resultados: Se reclutaron 476 pacientes, de los cuales 40,8% eran ≥ 65 años, 32,6% tenían HTA, 14,4% DM y 27,9% dislipemia. Un 16,16% de los pacientes tuvieron un índice de Lee ≥ 1.El 80,5% de los pacientes presentaban un ECG normal, el 6,5% alteraciones menores y el 13%, alteraciones mayores. En el análisis multivariante, la edad ≥ 65 años y la presencia de HTA se mostraron como factores de riesgo independiente para presentar alteraciones en el ECG totales y mayores.El índice de Lee ≥ 1 no se asoció con un mayor riesgo de alteraciones electrocardiográficas.ConclusiónLos pacientes ≥ 65 años o aquellos con HTA tienen mayor riesgo de presentar alteraciones electrocardiográficas mayores, por lo que recomendamos incluir en estos el ECG como prueba diagnóstica preoperatoria de rutina en cirugía no cardiaca.(AU)

Pulso pulmonar visualizado a través de derrame pleural como signo diagnóstico de atelectasia obstructiva completa del pulmón izquierdo en paciente crítico con insuficiencia respiratoria / Lung pulse visualized through pleural effusion as a diagnostic sign of complete obstructive atelectasis of the left lung in a critical patient with respiratory failure

La atelectasia obstructiva completa del pulmón es producida por un bloqueo de la conducción del aire a nivel de uno de los bronquios principales por secreciones o cuerpos extraños. Varios signos ecográficos pulmonares se han correlacionado con esta entidad. Describimos el caso de una paciente ingresada en la unidad de cuidados críticos posquirúrgicos en el que la ecografía pulmonar llevó al diagnóstico de esta complicación y en el que la presencia de derrame pleural permitió la visualización directa del pulso pulmonar, signo que previamente solo ha sido descrito mediante interpretación de artefactos ecográficos

Complete obstructive atelectasis occurs when mucous or a foreign body obstruct one of the main bronchi. Several lung ultrasound signs have been associated with this entity. We describe the case of a patient admitted to the surgical critical care unit in whom lung ultrasound led to a diagnosis of complete obstructive atelectasis, and the presence of pleural effusion provided direct visualization of lung pulse, a sign that has only previously been described by interpreting ultrasound artifacts
