RESUMO
Introduction: Status asthmaticus (SA) and near-fatal asthma (NFA) are life-threatening conditions that continue to present a management challenge for physicians. Extracorporeal Membrane Oxygenation (ECMO) has been employed as a last resort in treating these patients. Case presentation: We described six patients who were admitted to the ICU for NFA and received ECMO treatment at a high-complexity institution in Cali, Colombia, between 2015 and 2019. All patients are registered in the ELSO registry. Baseline patient characteristics, arterial blood gases (ABG), ventilatory parameters, and complications were collected as specified in the ELSO registry form. Efficacy was analyzed in terms of the improvement in respiratory acidosis, the number of ventilator-free days (VFD), and a reduction in mechanical power (MP). MP, which refers to the energy associated with the mechanical forces involved in breathing and the functioning of the respiratory system, was calculated using a mathematical formula. Safety was evaluated based on the incidence of complications. After 12 hours of ECMO, we achieved a correction of respiratory acidosis, a significant decrease in all ventilatory parameters, and a reduction in MP ranging from 52.8% to 89%. There was one mortality. Among the five surviving patients, all except one, who required a tracheostomy, had a high VFD score, with a mode of 26 days, demonstrating a reduction in ventilation time. Conclusion: Further randomized controlled trials are needed to fully understand the efficacy and safety profiles of ECMO in SA/NFA. MP is being widely used to achieve safer ventilation, and although more data is required, it appears to be a promising option for evaluating the risk of developing VILI and the success of the therapy.
RESUMO
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.
RESUMO
Resumen Introducción: La endocarditis infecciosa es una enfermedad de baja incidencia y alta morbilidad. Puede tener un curso agudo o subagudo, con complicaciones que están directamente relacionadas con la mortalidad y varían según el agente infeccioso; el más frecuente es Staphylococcus aureus. Dependiendo de la condición clínica se puede elegir una terapia antimicrobiana exclusiva o una terapia combinada (antimicrobiana y cirugía); la elección adecuada impacta en las tasas de sobrevida. Objetivo: Describir las características clínicas, microbiológicas y ecocardiográficas en pacientes con endocarditis infecciosa y analizar la mortalidad según el tratamiento recibido (terapia antimicrobiana o terapia combinada). Método: Estudio de cohorte retrospectivo, realizado en el Hospital Universitario Fundación Valle del Lili, en Cali, Colombia, en el que se incluyeron pacientes hospitalizados mayores de 18 años que cumplían los criterios de Duke modificados para diagnóstico de endocarditis infecciosa. Se evaluaron dos cohortes según hubieran recibido tratamiento antimicrobiano exclusivo o terapia combinada. Los pacientes fueron seguidos hasta el egreso hospitalario. Resultados: De 101 pacientes, 58 recibieron terapia antimicrobiana y 43 terapia combinada. La sobrevida global fue del 77.35%; el grupo de terapia combinada tuvo una hazard ratio ajustada de 0.13 (intervalo de confianza del 95%: 0.036-0.505; p = 0.003). La tasa de mortalidad calculada por 1000 días-persona fue de 25.9 con terapia antimicrobiana y de 4.33 con terapia combinada. Conclusiones: El grupo de terapia combinada tuvo más complicaciones y mayor estancia en la unidad de cuidados intensivos, pero menores tasas de mortalidad que los pacientes con terapia antimicrobiana exclusiva. De acuerdo con las indicaciones actuales de manejo quirúrgico descritas en las guías internacionales, se pueden obtener excelentes resultados en los pacientes más enfermos.
Abstract Introduction: Infective endocarditis is a disease of low incidence but high morbidity. It can have an acute or subacute course, with complications that are directly related to mortality and vary according to the infectious agent; the most common is Staphylococcus aureus. Based on the clinical condition, an exclusive antimicrobial therapy or a combined therapy (antimicrobial and surgery) can be chosen; their proper choice impacts survival rates. Objective: To describe the clinical, microbiological and echocardiographic characteristics in patients with infective endocarditis and to analyze how mortality behaved according to the treatment received (antimicrobial therapy or combined therapy). Method: A retrospective cohort study, carried out at the Fundación Valle del Lili University Hospital, Cali, Colombia, which included hospitalized patients over 18 years of age who met modified Duke criteria for the diagnosis of infective endocarditis. Two cohorts were evaluated according to treatment: exclusive antimicrobial and combined therapy. They were followed until discharge from the hospital. Results: Of 101 patients, 58 received antimicrobial therapy and 43 combined therapy. Overall survival was 77.35%, the combined therapy group had an adjusted hazard ratio of 0.13 (95% confidence interval: 0.036-0.505; p = 0.003). The mortality rate calculated per 1000 person-days was 25.9 in antimicrobial therapy and 4.33 in combination therapy. Conclusions: the combined therapy group had more complications and a longer hospital stay in the ICU, but lower mortality rates than the patients on exclusive antimicrobial therapy. According to the current indications for surgical management described in international guidelines, excellent results can be obtained in sicker patients.
