Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial
Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt
Tratamiento de aorta abdominal e ilíacas con técnica endovascular: Experiencia quirúrgica Treatment of abdominal aorta and iliac arteries with endovascular technique
Antecedentes: desde 1991 la técnica endovascular se ha aplicado con éxito en el manejo de los aneurismas de aorta infrarrenal, y se ha perfeccionado de manera tal que rápidamente se ha convertido en una alternativa para pacientes de alto riesgo para la cirugía convencional. Objetivo: describir los resultados institucionales en el manejo de las patologías de aorta abdominal e ilíacas mediante técnica endovascular desde 2003 a 2005. Diseño-Método: estudio descriptivo, longitudinal, retrospectivo, en el que se analizaron las historias clínicas de los pacientes sometidos a procedimiento endovascular de aorta abdominal e ilíacas. El análisis se realizó en Stata 8,0 S/E. Resultados: a 9 pacientes se les realizó exclusivamente manejo de lesiones en aorta abdominal e ilíacas. Todos los pacientes del estudio fueron hombres con edad media de 68,9 + 8,1 años. Los diagnósticos fueron aneurisma de aorta infrarrenal en 6 pacientes y aneurismas anastomóticos en los 3 restantes. Se evidenció requerimiento de endoprótesis en promedio de 1,9 + 0,8. Se realizó puente femoro-femoral como procedimiento simultáneo en 4 de los 9 pacientes. El 77,8% de los pacientes no tuvo complicaciones. La mortalidad por el procedimiento alcanzó el 22% (2 pacientes), si bien cabe anotar que las complicaciones se presentaron sólo en esos dos pacientes. Conclusiones: la exclusión de aneurismas de aorta y de ilíacas con endoprótesis modulares, se está implementando ampliamente como una opción válida de tratamiento, con resultados excelentes que evitan los riesgos de la intervención convencional y la morbilidad asociada.Antecedents: since 1991 endovascular technique has been successfully used in the management of infra-renal aortic aneurysms and it has been improved in such a way that it has quickly turned into an alternative for patients considered having high risk for conventional surgery. Objective: describe the institutional results in the management of abdominal aortic pathologies through endovascular technique from 2003 to 2005. Design-Method: descriptive, longitudinal, retrospective study in which clinical histories of patients that underwent an endovascular procedure of abdominal aorta and iliac arteries were analyzed. The analysis was performed in Stata 8,0 S/E. Results: 9 patients received exclusively treatment for abdominal aortic and iliac lesions. All were male individuals with mean age 68.9 ± 8.1 years. 6 patients had diagnosis of infra-renal aortic aneurysm and the other 3 had anastomotic aneurysms. Requirement of endoprosthesis was evidenced in an average of 1.9 ± 0.8. Femoro-femoral bypass surgery was performed as simultaneous procedure in 4 of the 9 patients. 77.8% of patients had no complications. Mortality due to the procedure was 22% (2 patients) and it is important to notice that only these 2 patients had complications. Conclusions: exclusion of aortic and iliac aneurysms with modular endoprosthesis is being widely implemented as a valid treatment option, with excellent results that avoid the risks of conventional surgery and its associated morbidity
Manejo endovascular de la aorta torácica Endovascular treatment of thoracic aorta
En comparación con el tratamiento convencional, la terapia endovascular en aneurisma de aorta torácica, presenta los mejores resultados, por lo que se convierte en el tratamiento de elección para la patología de aorta torácica descendente endovascular, por su baja morbimortalidad perioperatoria. El tratamiento quirúrgico por vía retroperitoneal y/o endovascular para aneurisma de aorta abdominal infrarrenal, resulta ser especialmente seguro en pacientes octogenarios o con alta morbilidad. Esta cohorte institucional presenta resultados perioperatorios y en el seguimiento, similares a los reportados en la literatura mundial.Compared with the conventional treatment, endovascular therapy in thoracic aortic aneurysm shows the best results, being the election treatment for the pathology of the descending thoracic aorta, due to its low peri-operative morbid-mortality. Surgical treatment by retro-peritoneal route and/or endovascular for infra-renal abdominal aortic aneurysm is especially safe in octogenarian patients or in those with a high mortality rate. This institutional cohort show peri-operative and follow-up results similar to those reported in the world literature
Arteria carótida y placa "carótida un órgano" Carotid artery and plaque. "carotid: an organ"
En estos momentos es posible hacer recomendaciones sobre las indicaciones de la endarterectomía carotídea, basadas en los ensayos clínicos publicados y en la revisión de grandes series quirúrgicas. Las indicaciones para la cirugía dependerán del grado de estenosis y de la morfología de la placa, así como del estado clínico del paciente y de la morbi-mortalidad del equipo quirúrgico. Este al igual que otros estudios con grandes series de casos, evidencia que la endarterectomía carotídea y/o el manejo endovascular, realizado por equipos expertos, es un procedimiento seguro en pacientes con indicación quirúrgica.It is now possible to recommend indications for aortic endarterectomy, based on published clinical essays and revision of large surgical series. Surgery indications will depend on the stenosis degree and the plaque morphology, as well as on the patient's clinical state and the morbid-mortality in this surgical team. As other studies with large case series, evidences that carotid endarterectomy and/or endovascular management, when realized by expert teams, is a safe procedure in patients with surgical indication
