, , , , , , Mechanical ventilation can be a life-saving intervention, but its implementation requires a multidisciplinary approach, with an understanding of its indications and contraindications due to the potential for complications. The management of mechanical ventilation should be part of the curricula during clinical training; however, trainees and practicing professionals frequently report low confidence in managing mechanical ventilation, often seeking additional sources of knowledge. Review articles, consensus statements and clinical practice guidelines have become important sources of guidance in mechanical ventilation, and although clinical practice guidelines offer rigorously developed recommendations, they take a long time to develop and can address only a limited number of clinical questions. The Associação de Medicina Intensiva Brasileira and the Sociedade Brasileira de Pneumologia e Tisiologia sponsored the development of a joint statement addressing all aspects of mechanical ventilation, which was divided into 38 topics. Seventy-five experts from all regions of Brazil worked in pairs to perform scoping reviews, searching for publications on their specific topic of mechanical ventilation in the last 20 years in the highest impact factor journals in the areas of intensive care, pulmonology, and anesthesiology. Each pair produced suggestions and considerations on their topics, which were presented to the entire group in a plenary session for modification when necessary and approval. The result was a comprehensive document encompassing all aspects of mechanical ventilation to provide guidance at the bedside. In this article, we report the methodology used to produce the document and highlight the most important suggestions and considerations of the document, which has been made available to the public in Portuguese.

Perspectives on invasive and noninvasive ventilatory support for critically ill patients are evolving, as much evidence indicates that ventilation may have positive effects on patient survival and the quality of the care provided in intensive care units in Brazil. For those reasons, the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB) and the Brazilian Thoracic Society (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT), represented by the Mechanical Ventilation Committee and the Commission of Intensive Therapy, respectively, decided to review the literature and draft recommendations for mechanical ventilation with the goal of creating a document for bedside guidance as to the best practices on mechanical ventilation available to their members. The document was based on the available evidence regarding 29 subtopics selected as the most relevant for the subject of interest. The project was developed in several stages, during which the selected topics were distributed among experts recommended by both societies with recent publications on the subject of interest and/or significant teaching and research activity in the field of mechanical ventilation in Brazil. The experts were divided into pairs that were charged with performing a thorough review of the international literature on each topic. All the experts met at the Forum on Mechanical Ventilation, which was held at the headquarters of AMIB in São Paulo on August 3 and 4, 2013, to collaboratively draft the final text corresponding to each sub-topic, which was presented to, appraised, discussed and approved in a plenary session that included all 58 participants and aimed to create the final document.

OBJECTIVES: To describe the population of aged as compared to young patients under mechanical ventilation and to analyze the mortality risk factors of this group in an intensive care unit. METHODS: This was a prospective observational trial in patients over 18 years of age, admitted in an intensive care unit and under mechanical ventilation, during one year. Patients were divided into two groups according to age: Group 1 - patients over 65 years old; and Group 2, 65 years old or younger. RESULTS: eighty one mechanic ventilation patients were included, 62 aged and 18 younger, mean ages from aged was 76 years, while in the younger it was 56 years. As compared to the control, aged patients had longer mechanic ventilation time , higher intensive care unit and hospital mortality: 63.1% versus 26.3% and 74.2% versus 47.4% (P<0.05), respectively. In addition, the aged under mechanic ventilation had increased desintubation failures, difficult ventilatory weaning and deaths directly related to respiratory dysfunction. The mechanic ventilation time was an independent risk factor for death in the intensive care unit in aged patients (OR= 2.7, p=0.02). The area under the ROC curve of mechanic ventilation about intensive care unit death was 0.92 (95% CI 0.85-0.97, p (area 0.5)=0.0001), cutoff point of 4 days, sensitivity 89.4% and specificity 77.1%. CONCLUSIONS: Mechanic ventilation patients over 65years of age have a worse prognosis than the younger, and the longer the mechanic ventilation time, the higher will be intensive care mortality.

Currently, aging of the population is a widespread global phenomenon. Therefore, the assessment of prognosis in elderly patients is needed. This study aims to identify risk factors in a population of elderly patients admitted in the intensive care unit METHODS: A prospective study in the intensive care unit of a general tertiary hospital was carried out for five months. Patients with 65 years or more of age, who stayed in the intensive care unit for 24 hours or more were included and those at the-end-of-life, patients readmitted to intensive care unit during the same hospital stay were excluded. RESULTS: In this study 199 patients were involved, with a mean age of 75.4±6.8 years, and 58.8% were female. Mortality was 57.3%. The mean APACHE II, SOFA, MODS and Katz index (assessment of daily activities) were respectively 20.0±5.8, 6.8±3.9, 2.4±1.9 and 5.3±1.6. Most patients were postoperative 59.3% and 41.6% were under invasive mechanical ventilation. At regression analysis, the independent determinants of higher mortality were: older age (76.9±6.7 years death versus 73.3±6.5 years discharge, P<0.001, OR=1.08, CI 95% 1.01-1. 16), the Katz index (4.9±1.9 deaths versus 5.7±0.9 discharge, p=0.001, OR=0.66, CI 95% 0.45-0.98), hyperglycemia (158.1±69.0 death versus 139.6±48.5 discharge p=0.041; OR=1.02; CI 95% 1.01-1.03) and need for mechanical ventilation at admission to the intensive care unit (57.0% death versus 20.5% discharge p <0.001, OR=3.57, CI 95% 1.24-10.3). CONCLUSION: Elderly patients admitted to the intensive care unit that have difficulties in performing daily activities, hyperglycemia and who are under invasive mechanical ventilation had a worse hospital prognosis.
