Rationale and study design for an Individualized PeriopeRative Open lung VEntilatory approach in Emergency Abdominal Laparotomy/scopy: study protocol for a prospective international randomized controlled trial.

BACKGROUND: Postoperative pulmonary complications (PPC) are the most frequent postoperative complications, with an estimated prevalence in elective surgery ranging from 20% in observational cohort studies to 40% in randomized clinical trials. However, the prevalence of PPCs in patients undergoing emergency abdominal surgery is not well defined. Lung-protective ventilation aims to minimize ventilator-induced lung injury and reduce PPCs. The open lung approach (OLA), which combines recruitment manoeuvres (RM) and positive end-expiratory pressure (PEEP) titration, aims to minimize areas of atelectasis and the development of PPCs; however, there is no conclusive evidence in the literature that OLA can prevent PPCs. The purpose of this study is to compare an individualized perioperative OLA with conventional standardized lung-protective ventilation in patients undergoing emergency abdominal surgery with clinical signs of intraoperative lung collapse. METHODS: Randomized international clinical trial to compare an individualized perioperative OLA (RM plus individualized PEEP and individualized postoperative respiratory support) with conventional lung-protective ventilation (standard PEEP of 5 cmH2O and conventional postoperative oxygen therapy) in patients undergoing emergency abdominal surgery with clinical signs of lung collapse. Patients will be randomised to open-label parallel groups. The primary outcome is any severe PPC during the first 7 postoperative days, including: acute respiratory failure, pneumothorax, weaning failure, acute respiratory distress syndrome, and pulmonary infection. The estimated sample size is 732 patients (366 per group). The final sample size will be readjusted during the interim analysis. DISCUSSION: The Individualized Perioperative Open-lung Ventilatory Strategy in emergency abdominal laparotomy (iPROVE-EAL) is the first multicentre, randomized, controlled trial to investigate whether an individualized perioperative approach prevents PPCs in patients undergoing emergency surgery.

Prognostic factors for deterioration of quality of life one year after admission to ICU for severe SARS-COV2 infection.

PURPOSE: Patients with COVID-19 present long-term symptoms collectively known as "post-COVID syndrome". Long-term manifestations are more frequent in patients requiring admission to Intensive Care Units (ICU), but the risk factors for their development are still unknown. This study explores the quality of life of patients with severe COVID-19 one year after their discharge from ICU. METHODS: Prospective observational study including 106 patients admitted to the ICU of a tertiary care hospital between March and August 2020. We analysed quality of life using the EuroQol-5D index (EQ-5D). We evaluated as possible risk factors associated with a worse value of the EQ-5D index the medical record, the clinical situation at hospital admission, the clinical situation at ICU admission and evolution in the ICU. As a secondary objective, we explored the presence of other frequent symptoms. RESULTS: Most patients (55.4%) reported that their quality of life worsened one year after admission. The mean perceived health status, on the EQ-VAS scale (0-100), was 70.4, with a median of 70 (RI 60-90). The median EQ-5D index was 0.91 (RI 0.76-1). The factors independently related to lower quality of life were female sex and duration of mechanical ventilation. Almost all (91%) of the patients had sequelae one year after discharge from the ICU. The most frequent manifestations were neuropsychiatric (71%). CONCLUSIONS: Critically ill COVID-19 patients worsen their quality of life more than one year after discharge. Female sex and duration of mechanical ventilation predict a lower quality of life assessed by the EQ-5D index.

Estudio de cohortes para evaluar la prevalencia de QT prolongado y arritmias en pacientes críticos durante la primera fase de la pandemia por COVID-19 / Cohort study to assess the prevalence of prolonged QT and arrhythmias in critically ill patients during the early phase of the COVID-19 pandemic

Antecedentes y objetivo: Los pacientes con infección por SARS-CoV-2 pueden presentar afectación cardiovascular, incluyendo miocarditis, arritmias y prolongación del intervalo QT. Nuestro objetivo fue evaluar el impacto de la COVID-19 y su tratamiento en la repolarización ventricular y el desarrollo de arritmias en pacientes críticos. Material y métodos: Estudio de cohortes retrospectivo de pacientes críticos con infección confirmada por SARS-CoV-2 durante un periodo de 3meses. Se registraron los datos clínicos relevantes y el tratamiento específico administrado para la COVID-19. Se consideró QTc prolongado cuando medía ≥460ms en mujeres y ≥450ms en hombres. Se registró la incidencia y el tipo de arritmias durante el mismo periodo. Resultados: Se evaluaron 77 pacientes con una edad media de 62±13años: 20 mujeres y 57 hombres. El 60% de los pacientes eran hipertensos, el 52% presentaban un IMC>30 y el 70% desarrollaron fracaso renal agudo durante el ingreso. El 56% de los pacientes presentaron prolongación del QTc. El 44% presentaron algún tipo de arritmia durante su estancia en la UCI, siendo en el 21% arritmias auriculares. La mortalidad global fue del 53%, sin diferencias entre los pacientes con o sin QTc prolongado. Conclusiones: En nuestra serie, una elevada proporción de pacientes críticos con COVID-19 han presentado QTc prolongado y arritmias. Los factores implicados se han relacionado con la elevación de biomarcadores cardiacos, la propia afectación miocárdica del virus y la medicación concomitante recibida en la UCI.(AU)

Introduction and objective: Patients with SARS-CoV-2 infection may present cardiovascular involvement including myocarditis, arrhythmias and QT interval prolongation. Our objective was to evaluate the impact of COVID-19 and its treatment on ventricular repolarization and development of arrhythmias in critically ill patients. Material and methods: Retrospective cohort study of critically ill COVID-19 patients during a 3-month period in whom at least one ECG was available. Relevant clinical data and specific treatment administered for COVID-19 were recorded. Prolonged QTc was considered prolonged when it measured ≥460ms in women and ≥450ms in men. The incidence and type of arrhythmias during the same period were recorded. Results: A total of 77 patients with a mean age of 62±13years, 20 women and 57 men, were evaluated. Sixty percent of the patients were hypertensive, 52% had a BMI>30, and 70% developed acute renal failure during admission. Some 56% of the patients presented QTc prolongation. Forty-four percent presented some type of arrhythmia during their stay in the ICU, 21% of which were atrial arrhythmias. Overall mortality was 53%, with no differences between patients with or without prolonged QTc. Conclusions: In our series, a high proportion of critical patients with COVID-19 presented prolonged QTc and arrhythmias. The factors involved have been related to the elevation of cardiac biomarkers, the myocardial involvement of the virus and concomitant medication received in the ICU.(AU)

Recommendations of the Society of Thoracic Surgery and the Section of Cardiothoracic and Vascular Surgery of the Spanish Society of Anesthesia, Resuscitation and Pain Therapy, for patients undergoing lung surgery included in an intensified recovery program.

In recent years, multidisciplinary programs have been implemented that include different actions during the pre, intra and postoperative period, aimed at reducing perioperative stress and therefore improving the results of patients undergoing surgical interventions. Initially, these programs were developed for colorectal surgery and from there they have been extended to other surgeries. Thoracic surgery, considered highly complex, like other surgeries with a high postoperative morbidity and mortality rate, may be one of the specialties that most benefit from the implementation of these programs. This review presents the recommendations made by different specialties involved in the perioperative care of patients who require resection of a lung tumor. Meta-analyzes, systematic reviews, randomized and non-randomized controlled studies, and retrospective studies conducted in patients undergoing this type of intervention have been taken into account in preparing the recommendations presented in this guide. The GRADE scale has been used to classify the recommendations, assessing on the one hand the level of evidence published on each specific aspect and, on the other hand, the strength of the recommendation with which the authors propose its application. The recommendations considered most important for this type of surgery are those that refer to pre-habilitation, minimization of surgical aggression, excellence in the management of perioperative pain and postoperative care aimed at providing rapid postoperative rehabilitation.

Clinical guide to perioperative management for videothoracoscopy lung resection (Section of Cardiac, Vascular and Thoracic Anesthesia, SEDAR; Spanish Society of Thoracic Surgery, SECT; Spanish Society of Physiotherapy).

The introduction of video-assisted thoracoscopic (VATS) techniques has led to a new approach in thoracic surgery. VATS is performed by inserting a thoracoscope through a small incisions in the chest wall, thus maximizing the preservation of muscle and tissue. Because of its low rate of morbidity and mortality, VATS is currently the technique of choice in most thoracic procedures. Lung resection by VATS reduces prolonged air leaks, arrhythmia, pneumonia, postoperative pain and inflammatory markers. This reduction in postoperative complications shortens hospital length of stay, and is particularly beneficial in high-risk patients with low tolerance to thoracotomy. Compared with conventional thoracotomy, the oncological results of VATS surgery are similar or even superior to those of open surgery. This aim of this multidisciplinary position statement produced by the thoracic surgery working group of the Spanish Society of Anesthesiology and Reanimation (SEDAR), the Spanish Society of Thoracic Surgery (SECT), and the Spanish Association of Physiotherapy (AEF) is to standardize and disseminate a series of perioperative anaesthesia management guidelines for patients undergoing VATS lung resection surgery. Each recommendation is based on an in-depth review of the available literature by the authors. In this document, the care of patients undergoing VATS surgery is organized in sections, starting with the surgical approach, and followed by the three pillars of anaesthesia management: preoperative, intraoperative, and postoperative anaesthesia.

La introducción de técnicas toracoscópicas asistidas por video en cirugía torácica (VATS) ha permitido realizar un nuevo enfoque en la cirugía torácica. El acceso videotoracoscópico se realiza con pequeñas incisiones, preservando al máximo los músculos y los tejidos. En la actualidad, la VATS se considera de elección en la mayoría de los procedimientos torácicos, principalmente debido a la menor morbimortalidad asociada. La resección pulmonar por VATS presenta reducción de las fugas de aire prolongadas, arritmias, neumonía, dolor postoperatorio y una disminución de los marcadores inflamatorios. Esta reducción de las complicaciones postoperatorias está vinculada a una reducción de la estancia hospitalaria, siendo los pacientes de alto riesgo y con poca tolerancia a la toracotomía los principales beneficiarios de esta técnica.En comparación con la toracotomía convencional, los?resultados?oncológicos de la cirugía VATS son similares o incluso superiores a los de la cirugía abierta.Este documento, de redacción multidisciplinar, consensuado por el grupo de trabajo de cirugía torácica de la Sociedad Española de Anestesiología y Reanimación (SEDAR), de la Sociedad Española de Cirugía Torácica (SECT) y la Asociación Española de Fisioterapia (AEF), pretende estandarizar y difundir, con base en la bibliografía más actual, las mejores pautas de manejo clínico perioperatorio de los pacientes que se someten a una cirugía de resección pulmonar por VATS. Cada recomendación parte de una revisión de la literatura disponible y analizada en profundidad por los autores.Con el objetivo de dirigir el curso asistencial que seguirá el paciente que se somete a una cirugía pulmonar por VATS, esta guía se organiza inicialmente en el enfoque quirúrgico, seguido de los tres puntos clásicos del proceso anestésico. Estos puntos son preoperatorio, intraoperatorio y postoperatorio.(AU)

Recomendaciones de la Sociedad Española de Cirugía Torácica y de la Sección de Cardiotorácica y Cirugía Vascular de la Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor, para los pacientes sometidos a cirugía pulmonar incluidos en un programa de recuperación intensificada / Recommendations of the Society of Thoracic Surgery and the Section of Cardiothoracic and Vascular Surgery of the Spanish Society of Anesthesia, Resuscitation and Pain Therapy, for patients undergoing lung surgery included in an intensified recovery program

En los últimos años se están implementando programas multidisciplinares que incluyen diferentes actuaciones durante el periodo pre, intra y postoperatorio, encaminadas a disminuir el estrés perioperatorio y, por tanto, a mejorar los resultados de los pacientes sometidos a intervenciones quirúrgicas. Inicialmente, estos programas se desarrollaron para cirugía colorrectal y de ahí se han ido extendiendo a otras cirugías. La cirugía torácica, considerada de elevada complejidad, al igual que otras cirugías con una alta tasa de morbimortalidad postoperatoria, puede ser una de las especialidades que más se beneficien de la implantación de estos programas. En esta revisión se presentan las recomendaciones elaboradas por diferentes especialidades implicadas en los cuidados perioperatorios de los pacientes que requieren la resección de un tumor pulmonar. Para la elaboración de las recomendaciones presentadas en esta guía se han tenido en cuenta los metaanálisis, las revisiones sistemáticas, los estudios controlados aleatorizados y no aleatorizados y los estudios retrospectivos realizados en pacientes sometidos a este tipo de intervenciones. Para la clasificación de las recomendaciones se ha empleado la escala GRADE, valorando, por un lado, el nivel de evidencia publicado sobre cada aspecto concreto, y por otro, la fuerza de la recomendación con la que los autores proponen su aplicación. Las recomendaciones consideradas más importantes para este tipo de cirugía son las que se refieren a la prehabilitación, a la minimización de la agresión quirúrgica, a la excelencia en el manejo del dolor perioperatorio y a los cuidados postoperatorios encaminados a proporcionar una rápida rehabilitación postoperatoria.(AU)

Diferencias del "inflamoma" en lavado broncoalveolar de pacientes sometidos a cirugía fumadores y no fumadores / Differences in bronchoalveolar lavage "inflammasome" between smokers and non-smokers undergoing thoracic surgery

Introducción. El riesgo de complicaciones postoperatorias es menor en aquellos pacientes que se abstiene de fumar en las 6 semanas previas a la intervención, esto podría deberse a diferencias en el perfil inflamatorio del pulmón. El objetivo de este estudio es medir las concentración de biomarcadores inflamatorios en el lavado broncoalveolar de dos cohortes de pacientes sometidos a cirugía torácica, una no fumadora o exfumadora con más de 6 semanas de abstinencia y otra de fumadores activos o con menos de 6 semanas de abstinencia. Métodos. Este estudio transversal de 226 pacientes mayores de 18 años, de ambos sexos elegibles, pudieron ser analizados 174 (55 fumadores y 119 no fumadores en las 6 semanas previas a la intervención) sometidos a cirugía torácica. Se determinaron en el lavado broncoalveolar previo a la cirugía del pulmón no intervenido IL-1, IL-2, IL-4, IL-6, IL-7, IL-8, IL10, IL-12, MCP-1 y TNF-alfa. Resultados. El grupo de fumadores resultó tener valores significativamente (p < 0,05) más elevados de IL-1: 136 (27) pg/ml vs 120 (21) pg/ml, IL-2: 2,22 (0,39) pg/ml vs 2,09 (0,4) pg/ml, IL-4: 0,64 (0,22) pg/ml vs 0,40 (0,06) pg/ml, IL-6: 6,6 (0,9) pg/ml vs 6,2 (0,7) pg/ml y MCP-1: 382 (28) pg/ml vs 352 (50) pg/ml, también mostró una espirometría más obstructiva: FEV1/FVC: 68 (5)% vs 75 (12)%, así como menor DLCO: 82 (22)% vs 96 (21)%. Conclusiones. Los pacientes fumadores en las 6 semanas previas a la cirugía tienen un estado inflamatorio pulmonar aumentado con respecto a los que no fumaron durante ese periodo

Introduction. The risk of postoperative complications is lower in those who abstain from smoking in the 6 weeks prior to the intervention; this could be due to differences in the lung inflammatory profile. The objective of this study is to measure the concentration of inflammatory biomarkers in the broncholveolar lavage of two cohorts of patients undergoing thoracic surgery: One consisting of smokers or non-smokers with more than 6 weeks of abstinence and other of smokers or ex-smokers with less than 6 weeks of abstinence. Methods. In this cross-sectional study from 226 eligible patients of sexes, 18 years or older, undergoing thoracic surgery, 174 could be analysed (55 smokers and 119 non-smokers in the 6 weeks prior to the intervention). IL-1, IL-2, IL-4, IL-6, IL-7, IL-8, IL10, IL-12, MCP-1 and TNF-alpha were determined in bronchoalveolar lavage prior to surgery. Results. the Group of smokers had values significantly (p < 0.05) higher of IL-1: 136 (27) pg/ml vs 120 (21) pg/ml, IL-2: 2.22 (0.39) pg/ml vs 2.09 (0.4) pg/ml, IL-4: 0.64 (0.22) pg/ml vs 0.40 (0.06) pg/ml, IL-6: 6.6 pg/ml (0.9) vs. 6.2 pg/ml (0.7) and MCP-1: 382 (28) pg/ml vs 352 (50) pg/ml. They also were more obstructive: FEV1/FVC: 68 (5)% vs. 75 (12)%, as well as they had lower DLCO: 82 (22)% vs 96 (21)%. Conclusions. Smokers in the 6 weeks prior to surgery have an increased lung inflammatory status with respect to those who did not smoke during this period

Are high-sensitivity troponins always reliable? Donor-recipient troponin transfusion in liver transplantation.

Blood troponins are used to diagnose perioperative myocardial injury and infarction. During liver transplantation, a passive donor-recipient troponin transfer with the graft may result in an increase of troponins in the transplant recipient questioning the diagnosis of myocardial injury. We present a case of liver transplantation with sudden elevation of recipient's serum troponin levels immediately after graft reperfusion and its subsequent normalization in which myocardial damage and other non-ischaemic potential causes were ruled out. Patient consent for publication was obtained prior to submission of the manuscript.

Postoperative pulmonary complications, pulmonary and systemic inflammatory responses after lung resection surgery with prolonged one-lung ventilation. Randomized controlled trial comparing intravenous and inhalational anaesthesia.

BACKGROUND: Recent studies report the immunomodulatory lung-protective role of halogenated anaesthetics during lung resection surgery (LRS) but have not investigated differences in clinical postoperative pulmonary complications (PPCs). The main goal of the present study was to compare the effect of sevoflurane and propofol on the incidence of PPCs in patients undergoing LRS. The second aim was to compare pulmonary and systemic inflammatory responses to LRS. METHODS: Of 180 patients undergoing LRS recruited, data from 174 patients were analysed. Patients were randomized to two groups (propofol or sevoflurane) and were managed otherwise using the same anaesthetic protocol. Bronchoalveolar lavage (BAL) was performed in both lungs before and after one-lung ventilation for analysis of cytokines. Arterial blood was drawn for measurement of the cytokines analysed in the BAL fluid at five time points. Intraoperative haemodynamic and respiratory parameters, PPCs (defined following the ARISCAT study), and mortality during the first month and yr were recorded. RESULTS: More PPCs were detected in the propofol group (28.4% vs 14%, OR 2.44 [95% CI, 1.14-5.26]). First-yr mortality was significantly higher in the propofol group (12.5% vs 2.3%, OR 5.37 [95% CI, 1.23-23.54]). Expression of lung and systemic pro-inflammatory cytokines was greater in the propofol group than in the sevoflurane group. Pulmonary and systemic IL-10 release was less in the propofol group. CONCLUSIONS: Our results suggest that administration of sevoflurane during LRS reduces the frequency of the PPCs recorded in our study and attenuates the pulmonary and systemic inflammatory response.
