Experience in the perioperative management of patients with hip fracture in southwestern Colombia. Retrospective cohort study

Introduction Hip fracture is one of the main causes of morbidity and mortality among the elderly population. In Colombia there is a shortage of scientific literature on the perioperative management of this population of patients. Objective To describe the perioperative management of hip fracture patients at a tertiary university hospital in Cali, Colombia. Methods An observational study was conducted with relational scope of a historical cohort of patients with hip fracture who underwent surgical management between January 2018 and June 2022. A non-probability sampling method was used and contingency tables were designed aimed at describing the relationship between the patients' characteristics and the postoperative outcomes. Results 235 patients were included, of which 57 % were males. The mean age was 79 years and 49.8 % were classified as ASA III or higher. Spinal anesthesia was the most commonly used technique in 63.4 % of the cases. The most frequent outcomes were delirium in 17.9 %, and acute kidney failure in 6.8 %. 83.4 % of the patients underwent surgery within 48 hours of admission to the emergency department and intra-hospital mortality was 2.6 %. Conclusions The results of this study provide relevant information to identify opportunities for improvement and their implementation, such as the reduction in the time elapsed until surgical management and the development of care protocols in the region.

Intensivist-led ultrasound-guided percutaneous tracheostomy: a phase IV cohort study / Traqueostomia percutânea guiada por ultrassom conduzida por intensivistas: um estudo de coorte de fase IV

ABSTRACT Objective: To describe, with a larger number of patients in a real-world scenario following routine implementation, intensivist-led ultrasound-guided percutaneous dilational tracheostomy and the possible risks and complications of the procedure not identified in clinical trials. Methods: This was a phase IV cohort study of patients admitted to three intensive care units of a quaternary academic hospital who underwent intensivist-led ultrasound-guided percutaneous tracheostomy in Brazil from September 2017 to December 2021. Results: There were 4,810 intensive care unit admissions during the study period; 2,084 patients received mechanical ventilation, and 287 underwent tracheostomy, 227 of which were performed at bedside by the intensive care team. The main reason for intensive care unit admission was trauma, and for perform a tracheostomy it was a neurological impairment or an inability to protect the airways. The median time from intubation to tracheostomy was 14 days. Intensive care residents performed 76% of the procedures. At least one complication occurred in 29.5% of the procedures, the most common being hemodynamic instability and extubation during the procedure, with only 3 serious complications. The intensive care unit mortality was 29.1%, and the hospital mortality was 43.6%. Conclusion: Intensivist-led ultrasound-guided percutaneous tracheostomy is feasible out of a clinical trial context with outcomes and complications comparable to those in the literature. Intensivists can acquire this competence during their training but should be aware of potential complications to enhance procedural safety.

RESUMO Objetivo: Descrever, com um número maior de pacientes em um cenário do mundo real após a implementação rotineira, a traqueostomia percutânea guiada por ultrassom conduzida por intensivistas e os possíveis riscos e complicações do procedimento não identificados em estudos clínicos. Métodos: Trata-se de estudo de coorte de fase IV de pacientes internados em três unidades de terapia intensiva de um hospital acadêmico quaternário que foram submetidos a traqueostomia percutânea guiada por ultrassom conduzida por intensivistas no Brasil de setembro de 2017 a dezembro de 2021. Resultados: Entre as 4.810 admissões na unidade de terapia intensiva durante o período do estudo, 2.084 pacientes receberam ventilação mecânica, e 287 foram submetidos a traqueostomia, 227 das quais foram realizadas à beira do leito pela equipe de terapia intensiva. O principal motivo para a admissão na unidade de terapia intensiva foi trauma, e para a realização de uma traqueostomia foi comprometimento neurológico ou incapacidade de proteger as vias aéreas. O tempo médio entre a intubação e a traqueostomia foi de 14 dias. Residentes de terapia intensiva realizaram 76% dos procedimentos. Ao menos uma complicação ocorreu em 29,5% dos procedimentos, sendo instabilidade hemodinâmica e extubação durante o procedimento as complicações mais comuns, com apenas três complicações graves. A mortalidade na unidade de terapia intensiva foi de 29,1%, e a mortalidade hospitalar foi de 43,6%. Conclusão: A traqueostomia percutânea guiada por ultrassom conduzida por intensivistas é viável fora do contexto de um estudo clínico com resultados e complicações comparáveis aos da literatura. Os intensivistas podem adquirir essa competência durante seu treinamento, mas devem estar cientes das possíveis complicações para aumentar a segurança do procedimento.

Adesão ao protocolo Enhanced Recovery After Surgery (ERAS) em cirurgia plástica de reconstrução mamária / Adherence to the Enhanced Recovery After Surgery (ERAS) protocol in breast reconstruction plastic surgery

Introdução: O protocolo Enhanced Recovery After Surgery Society (ERAS) revolucionou os cuidados perioperatórios, aprimorando o manejo intra-hospitalar e melhorando desfechos de pacientes submetidas a cirurgia plástica de reconstrução mamária. O objetivo deste estudo foi avaliar a adesão às recomendações do protocolo ERAS para cirurgia plástica em dois hospitais de referência do Sul do país. Método: Estudo transversal, utilizando banco de dados de prontuários, em dois hospitais do Sul do Brasil, nos anos de 2018 a 2021. A definição das variáveis a serem avaliadas foi baseada no protocolo ERAS mais recente proposto por Temple-Oberle e colaboradores. Os resultados foram analisados por epidemiologia descritiva. Resultados: A taxa média de cumprimento do protocolo ERAS por participante foi de 50,7%. O tempo médio de internação foi de 11 horas e 52 minutos. A quantidade de indicações com forte grau de recomendação atingida mostrou capacidade de diminuir tempo de internação (ρ de Spearman = -0,397) (p<0,001). Conclusão: A adesão a medidas de otimização perioperatória em cirurgia plástica de reconstrução mamária é capaz de reduzir tempo de internação dos pacientes. Entretanto, a taxa média de adesão por paciente ainda é baixa, tornando-se evidente a necessidade de otimizar os cuidados dos pacientes submetidos a esta cirurgia.

Introduction: The Enhanced Recovery After Surgery Society (ERAS) protocol has revolutionized perioperative care, improving in-hospital management and outcomes for patients undergoing breast reconstruction plastic surgery. This study evaluated adherence to the ERAS protocol recommendations for plastic surgery in two reference hospitals in the country's south. Method: Cross-sectional study using a medical record database in two hospitals in southern Brazil from 2018 to 2021. The definition of the variables to be evaluated was based on the most recent ERAS protocol proposed by Temple-Oberle and collaborators. The results were analyzed by descriptive epidemiology. Results: The average rate of compliance with the ERAS protocol per participant was 50.7%. The mean length of stay was 11 hours and 52 minutes. The number of indications with a strong degree of recommendation achieved showed the ability to reduce the length of stay (Spearman ρ = -0.397) (p<0.001). Conclusion: Adherence to perioperative optimization measures in breast reconstruction plastic surgery can reduce patients' hospital stays. However, the average adherence rate per patient is still low, making it evident the need to optimize the care of patients undergoing this surgery.

Perioperative hypertension

The effects of hypertension on perioperative outcomes are still unclear. No specific systolic or diastolic blood pressure measurement has been determined as the cutoff value to continue with a surgical plan or adjourn. This study is designed as a narrative review of the available scientific evidence on the perioperative management of hypertension. A search was conducted in Pubmed considering the title and abstract; 120 articles were pre-selected of which 55 papers were selected for full-text eligibility and 16 were excluded for a total of 39 articles including ACCF/AHA 2009 and ACC/AHA 2014 on perioperative cardiovascular care; 2013 ESH/ESC, 8 JNC, and the 2017 ACC/AHA/AAPA/ABC Guideline for the Prevention, detection, and management of hypertension in adults. Blood pressure values, target organ damage, and type of surgery should be considered for decision-making in the perioperative period. If surgery is elective, blood pressure fluctuations should be avoided and potential causes should be treated. A patient with mild hypertension with values below SBP 160 and DBP 110 mmHg may be managed in the ambulatory setting during the postoperative period, as long as the clinical conditions are favorable.

Los efectos de la hipertensión sobre los desenlaces durante el periodo perioperatorio aún no han quedado claramente establecidos. No se ha determinado una medición específica para la presión sistólica ni diastólica como punto de corte para continuar con el plan quirúrgico o suspenderlo. El presente estudio está diseñado a manera de revisión narrativa de la evidencia científica disponible sobre el manejo perioperatorio de la hipertensión. Se llevó a cabo una búsqueda en Pubmed, considerando el título y el resumen; se preseleccionaron 120 artículos, de los cuales se seleccionaron 55 para elegibilidad en texto completo y 16 se excluyeron, quedando un total de 39 artículos, incluyendo ACCF/AHA 2009 y ACC/AHA 2014 sobre el cuidado cardiovascular perioperatorio; 2013 ESH/ESC, 8 JNC, y la Guía del 2017 ACC/AHA/AAPA/ABC para la prevención, detección y manejo de la hipertensión en adultos. Se deben considerar los valores de la presión arterial, el daño a órgano diana y el tipo de cirugía para la toma de decisiones en el periodo perioperatorio. Si la cirugía es electiva, deben evitarse las fluctuaciones en la presión arterial y tratar activamente cualquiera de las causas potenciales. Un paciente con hipertensión leve, con valores por debajo de PAS 160 y PAD 110 mmHg puede manejarse de manera ambulatoria durante el período postoperatorio, siempre y cuando las condiciones clínicas sean favorables.

PERIOPERATIVE ANXIETY IN CHILDREN: NARRATIVE REVIEW

Preoperative anxiety in children is common and can have negative effects on their overall surgical experience. Several factors, such as age, personality traits, and past medical experiences, can contribute to increased preoperative anxiety. Behavioral interventions, such as distraction techniques, parental presence at induction of anesthesia, and preoperative preparation programs, can be effective in reducing anxiety. Behavioral family preparation programs have been found to reduce the number of children requiring preoperative sedation, but they may not be practical for all centers. Anesthesiologists and child life specialists can play an essential role in reducing anxiety in children by interacting with them in an age-appropriate way, providing therapeutic play experiences, and offering developmentally appropriate language. Distraction techniques, such as non-procedural distracting talk, electronic devices, music, stories, and guided imagery, can also help children cope with anxiety. Pharmacological interventions, such as sedative premedication, should be used with caution, especially for children with neurodevelopmental disorders, due to potential drug interactions and increased risks of upper airway obstruction.

Patient satisfaction in ambulatory anesthesia assessed by the Heidelberg Peri-anaesthetic Questionnaire: a cross-sectional study

Abstract Background: Service quality in anesthesiology has been frequently measured by morbidity and mortality. This measure increasingly considers patient satisfaction, which is the result of care from the client's perspective. Therefore, anesthesiologists must be able to build relationships with patients, provide understandable information and involve them in decisions about their anesthesia. This study aimed to evaluate the peri-anesthetic care provided by the anesthesia service in an ambulatory surgery unit using the Heidelberg Peri-anaesthetic Questionnaire. Methods: This cross-sectional study used the Heidelberg Peri-anaesthetic Questionnaire to evaluate 1211 patients undergoing ambulatory surgery. We selected questions that showed a greater degree of dissatisfaction and correlated them with patient characterization data (age, sex, education, and ASA physical status), anesthesia data (type, time, and prior experience), and surgical specialty. Results: Questions in which patients tended to show dissatisfaction involved fear of anesthesia and surgery, feeling cold, the urgent need to urinate, pain at the surgical site, and the team's level of concern and speed of response in relieving the patient's pain. Conclusion: The Heidelberg Peri-anaesthetic Questionnaire proved to be a useful tool in identifying points of dissatisfaction, mainly fear of anesthesia and surgery, feeling cold, the urgent need to urinate, pain at the surgical site, and the team's level of concern and speed of response in relieving the patient's pain in the population studied. These were correlated with patient, anesthesia, and surgical variables. This allows the establishment of priorities at the different points of care, with the ultimate goal of improving patient satisfaction regarding anesthesia care.

Factors associated with posoperative mortality in high perioperative risk patients. Cohort study / Factores asociados a mortalidad posoperatoria en pacientes de alto riesgo perioperatorio. Estudio de cohorte

Abstract Introduction: Determining perioperative risk is part of the strategies implemented with the aim of reducing morbidity and mortality in the surgical population in the world. Although there is no established definition, high perioperative risk is associated with the group of patients with the highest disease burden. Objective: To determine postoperative mortality and its associated factors in patients with high perioperative risk. Methods: Analytical observational cohort study of high perioperative risk patients included in the database (n = 843) of the anesthesia program in a high complexity hospital in Colombia, between January 2011 and April 2018. Pre and postoperative variables were analyzed using uni and multivariate logistic regression per protocol. Overall and stratified mortality were estimated and factors associated with their occurrence were analyzed. Finally, survival was analyzed, the primary outcome being overall cohort mortality and stratified high cardiovascular risk mortality. Results: Cumulative 7-day mortality was 3.68% (95% CI 2.40-4.95%) and 30-day mortality was 10.08% (95% CI 8.05-12.12%). Perioperative mortality in the high cardiovascular risk group in the first 7 days was 3.60% (95% CI 1.13-6.07%) and 14.86% (95% CI 10.15-19.58%) at 30 days. The following preoperative variables were associated with mortality: chronic obstructive pulmonary disease, chronic kidney disease, limited functional class and abdominal aortic aneurysm. A strong association was observed between postoperative complications and a significant increase in mortality rate; the most relevant complications were cerebrovascular events and cardiogenic shock. Conclusions: In this group of high perioperative risk patients, and in the subgroup of high cardiovascular risk patients, overall mortality at 7 and at 30 days was estimated to be above values reported in various countries. Mortality was significantly increased by the presence of preoperative factors and postoperative complications.

Resumen Introducción: La determinación del riesgo perioperatorio hace parte de las estrategias de reducción de la morbimortalidad en la población quirúrgica mundial. El alto riesgo perioperatorio, a pesar de no tener una definición establecida, corresponde al grupo con mayor carga de enfermedad. Objetivo: Establecer la mortalidad posoperatoria en pacientes de alto riesgo perioperatorio y sus factores asociados. Métodos: Estudio observacional analítico con diseño de cohorte, que incluyó pacientes del programa de anestesiología de alto riesgo perioperatorio de un hospital de alta complejidad en Colombia. Base de datos compuesta por n = 843, entre enero de 2011 y abril de 2018. Se analizaron variables pre y posoperatorias mediante regresión logística uni y multivariada por protocolo. Se calculó la mortalidad global y estratificada y se analizaron factores asociados a su ocurrencia. Finalmente, se realizó análisis de supervivencia. El desenlace primario fue la mortalidad global de la cohorte y la mortalidad estratificada para el alto riesgo cardiovascular. Resultados: La mortalidad acumulada a los primeros 7 días fue de 3,68 % (IC 95 %; 2,40 %-4,95 %) y a los 30 días 10,08 % (IC 95 %; 8,05 %-12,12 %). La mortalidad perioperatoria en el grupo de alto riesgo cardiovascular a los primeros 7 días fue de 3,60 % (IC 95 %; 1,13 %-6,07 %) y a los 30 días 14,86 % (IC 95 %; 10,15 %-19,58 %). Las siguientes variables preoperatorias estuvieron asociadas a la mortalidad: enfermedad pulmonar obstructiva crónica, enfermedad renal crónica, clase funcional limitada y aneurisma de aorta abdominal. Se observó una fuerte asociación entre complicaciones posoperatorias y un significativo incremento de la tasa de mortalidad; los más relevantes fueron el evento cerebro-vascular y el choque cardiogénico. Conclusiones: En este grupo de pacientes de alto riesgo perioperatorio, la mortalidad global a los 7 días y a los 30 días, y en el subgrupo de alto riesgo cardiovascular, se estimó por encima de los valores reportados en diversos países. La presencia de factores preoperatorios y las complicaciones posoperatorias aumentaron significativamente la mortalidad.

Quality of Life and Satisfaction in Patients Above and Under 65 Years Old Submitted to Total Knee Arthroplasty / Qualidade de vida e satisfação de pacientes com idade superior ou inferior a 65 anos submetidos a artroplastia total de joelho

Abstract Objective To compare the level of quality of life and satisfaction after two years of total knee arthroplasties between individuals above and below 65 years of age and to identify predictor factors of poor clinical outcome and low level of satisfaction in patients undergoing arthroplasty. Methods This is a retrospective cohort with data from patients diagnosed with knee osteoarthritis submitted to primary total knee arthroplasty from 2014 to 2018 (n= 190). Clinical outcomes were assessed using the following scores: visual analog scale (VAS) of pain, EQ-5D-3L and EUROQOL-VAS (quality of life scales), patient satisfaction level, and functional scale of the Knee Injury and Osteoarthritis Outcome Score (KOOS), collected through a questionnaire applied preoperatively, as well as 1, 3, 12 and 24 months after surgery. Results Patients < 65 years old presented significantly lower values (clinical worsening) in KOOS-pain and KOOS-symptoms. There are no differences in the principal clinical scores that assess pain, function, and quality of life after the procedure, as well as in the rate of satisfaction with the procedure, among patients < 65 years old when compared with patients ≥ 65 years old. It was also observed that patients who were not satisfied with the procedure in the 24-month evaluation presented clinical results in some analyzed scores (KOOS-pain and EQ-VAS) similar to patients who declared themselves satisfied. Conclusion Scores that assess pain, function, quality of life, as well as satisfaction rate are similar between patients < 65 years old and those ≥ 65 years old.

Resumo Objetivo Comparar a qualidade de vida e satisfação 2 anos após a artroplastia total de joelho em indivíduos com idade ≥ e < 65 anos e identificar fatores preditivos de pior evolução clínica e baixo nível de satisfação nestes pacientes. Métodos Trata-se de uma coorte retrospectiva de dados de pacientes com diagnóstico de osteoartrite de joelho submetidos a artroplastia total primária de joelho entre 2014 e 2018 (n= 190). Os resultados clínicos foram avaliados de acordo com os seguintes escores: escala visual analógica (EVA) de dor, EQ-5D-3L e EUROQOL-VAS (escalas de qualidade de vida), nível de satisfação do paciente e escala funcional do Knee Injury and Osteoarthritis Outcome Score (KOOS, na sigla em inglês). Estes dados foram coletados por meio de questionário aplicado no período pré-operatório e 1, 3, 12 e 24 meses após a cirurgia. Resultados Os pacientes < 65 anos apresentaram valores significativamente menores (piora clínica) nas escalas KOOS-dor e KOOS-sintomas. Não houve diferenças nas principais pontuações clínicas de dor, função e qualidade de vida após o procedimento, nem no índice de satisfação com a cirurgia, entre pacientes < 65 anos em comparação com aqueles ≥ 65 anos. Observamos também que os pacientes não satisfeitos com o procedimento à avaliação de 24 meses apresentaram resultados clínicos em alguns escores analisados (KOOS-dor e EQ-VAS) semelhantes aos dos pacientes que se declararam satisfeitos. Conclusão Os escores que avaliam dor, função, qualidade de vida e índice de satisfação são semelhantes entre os pacientes < 65 anos e aqueles ≥ 65 anos.

Association between enhanced recovery after surgery protocol compliance and clinical complications: a cohort study

Abstract Background Enhanced Recovery After Surgery (ERAS) protocol is composed by evidence-based interventions that aim to improve recovery through a reduction in surgical stress response. Although ERAS protocols have been introduced across the globe, exhaustive implementation is not as common. We aimed to study the ERAS protocol compliance in colorectal surgery, assessing the relationship between compliance and postoperative complications. Methods A single-center cohort study was conducted. All consecutive patients admitted to elective colorectal surgery were included. We assessed study endpoints according to ERAS protocol perioperative compliance score above 75%. Our primary endpoint was a composite of postoperative events, which includes in-hospital postoperative complications and need for reoperation after 30 days and need for readmission after discharge. Secondary endpoints were surgery-to-discharge time, postoperative use of only non-opioid adjuvants and the individual components of the primary endpoint. Results A total of 224 colorectal patients were included. The primary endpoint occurred in 59.2% (n = 58) of non-compliant patients comparing to 34.1% (n = 43) in compliant patients. In univariate analysis, compliance to ERAS protocol had an inferior risk for the primary endpoint (p< 0.001). In a logistic regression model, compliance was independently associated with a reduced risk for the primary endpoint with a odds-ratio of 0.42 (95% CI 0.23-0.75, p= 0.004). Conclusion Compliance with the ERAS protocol is associated with less complications, a reduced surgery-to-discharge time and use of only non-opioid adjuvants in the postoperative period. More studies are needed to target the most appropriate compliance goal.

Compliance with Enhanced Recovery After Surgery (ERAS) protocol recommendations for bariatric surgery in an obesity treatment center

Abstract Introduction The higher risk of perioperative complications associated with obesity has made anesthesiologists increasingly concerned with the management of obese patients. Measures that improve bariatric surgery patient safety have become essential. The implementation of ERAS protocols in several surgical specialties has made it possible to achieve appropriate outcomes as to surgery safety. The aim of this study was to evaluate patient compliance with the recommendations of an ERAS protocol for Bariatric Surgery (ERABS) at a hospital specialized in obesity treatment. Methods Cross-sectional study, using a medical record database, in a hospital certified as an International Center of Excellence in Bariatric and Metabolic Surgery. The definition of the variables to be assessed was based on the most recent ERABS proposed by Thorell et al. Results were analyzed using descriptive epidemiology. Results The study evaluated all patients undergoing bariatric surgery in 2019. Mean compliance with the recommendations per participant was 42.8%, with a maximum of 55.5%, and was distributed as follows: 22.6% of compliance with preoperative recommendations, 60% to intraoperative recommendations, and 58.1% to postoperative recommendations. The anesthesiologist is the professional who provides most measures for the perioperative optimization of bariatric surgery patients. In our study we found that anesthesiologists complied with only 39.5% of ERABS recommendations. Conclusions Mean compliance with ERABS recommendations per participant was 42.8%. Considering that the study was carried out at a hospital certified as an international center of excellence, the need for introducing improvements in the care of patients to be submitted to bariatric surgery is evident.

High versus low mean arterial pressure target in liver transplant patients. An open, controlled, single-center, randomized clinical trial - Protocol and methods (LIVER-PAM) / Alto versus baixo alvo de pressão arterial média em pacientes submetidos a transplante hepático. Um estudo clínico aberto, controlado, unicêntrico e randomizado -Protocolo e métodos (LIVER-PAM)

ABSTRACT Objective: To explain the rationale and protocol of the methods and analyses to be used in the LIVER-PAM randomized clinical trial, which seeks to understand whether a higher mean arterial pressure is capable of reducing the incidence of renal dysfunction postoperatively after liver transplantation. Methods: LIVER-PAM is an open-label, randomized, controlled, singlecenter clinical trial. Patients randomized to the intervention group will have a mean arterial pressure of 85 - 90mmHg in the initial 24 hours of postoperative management, while patients in the control group will have a mean arterial pressure of 65 - 70mmHg in the same period. A sample of 174 patients will be required to demonstrate a 20% reduction in the absolute incidence of renal dysfunction, with a power of 80% and an alpha of 0.05. Conclusion: If a 20% reduction in the absolute incidence of renal dysfunction in the postoperative period of liver transplantation is achieved with higher target mean arterial pressure in the first 24 hours, this would represent an inexpensive and simple therapy for improving current outcomes in the management of liver transplant patients. ClinicalTrials.gov Registry:NCT05068713

RESUMO Objetivo: Explicitar o racional e o protocolo de métodos e análises a serem utilizadas no ensaio clínico randomizado LIVER-PAM, que busca entender se um nível mais alto de pressão arterial média é capaz de reduzir a incidência de disfunção renal no pós-operatório de transplante hepático. Métodos: O LIVER-PAM é um estudo clínico randomizado, controlado, unicêntrico e aberto. Pacientes randomizados para o grupo intervenção terão como alvo de pressão arterial média 85 - 90mmHg nas 24 horas iniciais do manejo pós-operatório, enquanto pacientes do grupo controle terão como alvo de pressão arterial média 65 - 70mmHg no mesmo período. Uma amostra de 174 pacientes será necessária para demonstrar redução de 20% na incidência absoluta de disfunção renal, com poder de 80% e alfa de 0,05. Conclusão: Se a redução de 20% da incidência absoluta de disfunção renal no pós-operatório de transplante hepático for obtida com alvos maiores de pressão arterial média nas primeiras 24 horas, o manejo do paciente nesse cenário encontraria uma terapia barata e simples para a melhoria dos desfechos atuais.

Effectiveness of an Educational Intervention with Guidelines from the Total Acceleration of Postoperative Recovery Project (ACERTO) in Gynecology / Efetividade de uma intervenção educativa com diretrizes do projeto Aceleração da Recuperação Total Pós-operatória (ACERTO) na ginecologia

Abstract Objective To evaluate the effectiveness of an educational intervention among gynecologists about recommendations of the Total Acceleration of Postoperative Recovery (ACERTO, in the Portuguese acronym) project derived from the solid foundations of Enhanced Recovery After Surgery (ERAS) guidelines to optimize hospital care for surgical-gynecological patients. Methods Educational intervention through monthly 1-hour long meetings (3 months), with the application of an objective questionnaire about specific knowledge of the ACERTO project between before and after educational intervention phases, for gynecologists, after approval by the ethics committee and signature of informed consent by participants, in a federal university hospital. Results Among the 25 gynecologists who agreed to participate, the educational intervention could be effective with a statistically significant difference between the phases before and after the intervention for the main recommendations of the ACERTO project, such as abbreviation of preoperative fasting (p = 0.006), venous thromboembolism prophylaxis (p = 0.024), knowledge and replication of ACERTO (p = 0.034), and multimodal analgesia (p = 0.021). Conclusion An educational intervention, through clinical meetings with exposition and discussion of the recommendations of the ACERTO project based on the ERAS protocol can be effective for the knowledge and possibility of practical application of the main measures, such as abbreviation of preoperative fasting, multimodal analgesia, and prophylaxis of thrombosis among gynecologists.

Resumo Objetivo Avaliar a efetividade de uma intervenção educativa entre ginecologistas de um hospital universitário a fim de capacitar o conhecimento científico das recomendações do projeto Aceleração da Recuperação Total Pós-operatória ACERTO, derivado das bases sólidas do protocolo Enhanced Recovery After Surgery (ERAS) para otimizar a assistência hospitalar de pacientes cirúrgico-ginecológicas.

Surgical treatment of craniovertebral stenosis in two siblings with type vi mucopolysaccharidosis / Tratamento cirúrgico de estenose craneo-vertebral em dois irmãos com mucopolisacaredose tipo vi / Tratamiento quirúrgico de estenosis craneo-vertebral en dos hermanos con mucopolisacaridosis tipo vi

ABSTRACT We describe two cases of surgical treatment of craniovertebral stenosis in preschool-aged brothers with Maroteaux-Lamy (MPS type VI) syndrome. The older brother was diagnosed with MPS during her second pregnancy. Literature describing familial cases of the disease and the treatment strategy in young children with MPS type VI and spinal canal stenosis is scarce. Based on the presented observations, indications, surgical treatment approaches, and perioperative management of patients with mucopolysac-charidosis are suggested. MPS type VI may have familial forms of the disease and the course of craniovertebral stenosis is similar in siblings. Surgical treatment of craniovertebral stenosis in these patients should be performed timely. We adhere to the point of view of early treatment of craniovertebral stenosis in patients with MPS before irreversible spinal cord dysfunction develops. Level of Evidence IV; Prognostic Studies - Investigating the Effect of a Patient Characteristic on the Outcome of Disease and Case series.

Resumo: Descreve-se dois casos de tratamento cirúrgico de estenose craniovertebral entre irmãos em idade pré-escolar com síndrome de Maroteaux-Lamy (MPS tipo VI). O irmão mais velho foi diagnosticado com MPS durante a segunda gravidez. A literatura que descreve casos familiares da doença e a estratégia de tratamento em crianças pequenas com MPS tipo VI e estenose do canal raquidiano é escassa. Com base nas observações apresentadas, foram sugeridas indicações, abordagens de tratamento cirúrgico e manejo perioperatório de pacientes com mucopolissacaridose. A MPS tipo VI pode apresentar formas familiares da doença e o curso da estenose craniovertebral é semelhante entre irmãos. O tratamento cirúrgico da estenose craniovertebral nesses pacientes deve ser realizado em tempo hábil. Adere-se ao conceito de tratamento precoce da estenose craniovertebral em pacientes com MPS antes que se desenvolva uma disfunção irreversível da medula espinhal. Nível de Evidência IV; Estudos Prognósticos - Investigando o Efeito de uma Característica de Paciente sobre o Resultado de uma Doença e de uma Série de Casos.

Resumen: Se describen dos casos de tratamiento quirúrgico de estenosis craneovertebral en hermanos de edad preescolar con síndrome de Maroteaux-Lamy (MPS tipo VI). Al hermano mayor se le diagnosticó MPS durante el segundo embarazo. La bibliografía que expone casos familiares de la enfermedad y la estrategia de tratamiento en niños pequeños con MPS tipo VI y estenosis del tubo vertebral es escasa. Sobre el fundamento de las observaciones presentadas, se sugieren indicaciones, enfoques de tratamiento quirúrgico y manejo perioperatorio de pacientes con mucopolisacaridosis. La MPS tipo VI puede presentar formas familiares de la enfermedad y el curso de la estenosis craneovertebral es semejante en los hermanos. El tratamiento quirúrgico de la estenosis craneovertebral en estos pacientes debe realizarse tempranamente. Se adhiere al planteamiento del tratamiento precoz de la estenosis craneovertebral en pacientes con MPS anticipándose al desarrollo de una disfunción irreversible de la médula espinal.

Perioperative mechanical ventilation strategy for COVID-19 patients: Recommendation / 中国胸心血管外科临床杂志

@#Since December 2019, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has gradually spread all over the world. With the implementation of class B infectious disease management policy for coronavirus disease 2019 (COVID-19), China has experienced a pandemic. For patients receiving a time-sensitive or emergency surgery, SARS-CoV-2 infection may increase the risk of postoperative pulmonary complications. An appropriate perioperative mechanical ventilation strategy, such as lung protective ventilation strategy, is particularly important for preventing postoperative pulmonary complications in patients undergoing general anesthesia. In addition, how to protect medical personnel from being infected is also the focus we need to pay attention to. This article will discuss the perioperative mechanical ventilation strategy for COVID-19 patients and the protection of medical personnel, in order to provide reference for the development of guidelines.
