, , , , , , , , , , , , To describe the effects of balanced solution use on the short-term outcomes of patients with traumatic brain injury enrolled in BaSICS trial.
Patients were randomized to receive either 0.9% saline or balanced solution during their intensive care unit stay. The primary endpoint was 90-day mortality, and the secondary outcomes were days alive and free of intensive care unit stay at 28 days. The primary endpoint was assessed using Bayesian logistic regression. The secondary endpoint was assessed using a Bayesian zero-inflated beta binomial regression.
We included 483 patients (236 in the 0.9% saline arm and 247 in the balanced solution arm). A total of 338 patients (70%) with a Glasgow coma scale score ≤ 12 were enrolled. The overall probability that balanced solutions were associated with higher 90-day mortality was 0.98 (OR 1.48; 95%CrI 1.04 - 2.09); this mortality increment was particularly noticeable in patients with a Glasgow coma scale score below 6 at enrollment (probability of harm of 0.99). Balanced solutions were associated with -1.64 days alive and free of intensive care unit at 28 days (95%CrI -3.32 - 0.00) with a probability of harm of 0.97.
There was a high probability that balanced solutions were associated with high 90-day mortality and fewer days alive and free of intensive care units at 28 days.

ABSTRACT OBJECTIVE: To evaluate end-of-life procedures in intensive care units. METHODS: A questionnaire was prepared by the End-of-Life Study Group of the Argentinean, Brazilian and Uruguayan Intensive Care societies, collecting data on the participants’ demographics, institutions and limit therapeutic effort (LTE) decision making process. During this cross sectional study, the societies’ multidisciplinary teams members completed the questionnaire either during scientific meetings or online. The variables were analyzed with the Chi-square test, with a p<0.05 significance level. RESULTS: 420 professionals completed the questionnaire. The Brazilian units had more beds, unrestricted visit was less frequent, their professionals were younger and worked more recently in intensive care units, and more non-medical professionals completed the questionnaire. Three visits daily was the more usual number of visits for the three countries. The most influencing LTE factors were prognosis, co-morbidities, and therapeutic futility. In the three countries, more than 90% of the completers had already made LTE decisions. Cardiopulmonary resuscitation, vasoactive drugs administration, dialysis and parenteral nutrition were the most suspended/refused therapies in the three countries. Suspension of mechanic ventilation was more frequent in Argentina, followed by Uruguay. Sedation and analgesia were the less suspended therapies in the three countries. Legal definement and ethical issues were mentioned as the main barriers for the LTE decision making process. CONCLUSION: LTE decisions are frequent among the professionals working in the three countries’ intensive care units. We found a more proactive LTE decision making trend In Argentina, and more equity for decisions distribution in Uruguay. This difference appears to be related to the participants’ different ages, experiences, professional types and genders.

Withholding of treatment in patients with terminal disease is increasingly common in intensive care units, throughout the world. Notwithstanding, Brazilian intensivists still have a great difficulty to offer the best treatment to patients that have not benefited from curative care. The objective of this comment is to suggest an algorithm for the care of terminally ill patients. It was formulated based upon literature and the experience of experts, by members of the ethics committee and end-of-life of AMIB - Brazilian Association of Intensive Care.

OBJECTIVES: Due to the dramatic medical breakthroughs and an increasingly ageing population, the proportion of patients who are at risk of dying following surgery is increasing over time. The aim of this study was to evaluate the outcomes and the epidemiology of non-cardiac surgical patients admitted to the intensive care unit. METHODS: A multicenter, prospective, observational, cohort study was carried out in 21 intensive care units. A total of 885 adult surgical patients admitted to a participating intensive care unit from April to June 2006 were evaluated and 587 patients were enrolled. Exclusion criteria were trauma, cardiac, neurological, gynecologic, obstetric and palliative surgeries. The main outcome measures were postoperative complications and intensive care unit and 90-day mortality rates. RESULTS: Major and urgent surgeries were performed in 66.4% and 31.7% of the patients, respectively. The intensive care unit mortality rate was 15%, and 38% of the patients had postoperative complications. The most common complication was infection or sepsis (24.7%). Myocardial ischemia was diagnosed in only 1.9% of the patients. A total of 94 % of the patients who died after surgery had co-morbidities at the time of surgery (3.4 ± 2.2). Multiple organ failure was the main cause of death (53%). CONCLUSION: Sepsis is the predominant cause of morbidity in patients undergoing non-cardiac surgery. In this patient population, multiple organ failure prevailed as the most frequent cause of death in the hospital.

The objective of this review was to evaluate current knowledge regarding terminal illness and palliative care in the intensive care unit, to identify the major challenges involved and propose a research agenda on these issues The Brazilian Critical Care Association organized a specific forum on terminally ill patients, to which were invited experienced and skilled professionals on critical care. These professionals were divided in three groups: communication in the intensive care unit, the decision making process when faced with a terminally ill patient and palliative actions and care in the intensive care unit. Data and bibliographic references were stored in a restricted website. During a twelve hour meeting and following a modified Delphi methodology, the groups prepared the final document. Consensual definition regarding terminality was reached. Good communication was considered the cornerstone to define the best treatment for a terminally ill patient. Accordingly some communication barriers were described that should be avoided as well as some approaches that should be pursued. Criteria for palliative care and palliative action in the intensive care unit were defined. Acceptance of death as a natural event as well as respect for the patient's autonomy and the nonmaleficence principles were stressed. A recommendation was made to withdraw the futile treatment that prolongs the dying process and to elected analgesia and measures that alleviate suffering in terminally ill patients. To deliver palliative care to terminally ill patients and their relatives some principles and guides should be followed, respecting individual necessities and beliefs. The intensive care unit staff involved with the treatment of terminally ill patients is subject to stress and tension. Availability of a continuous education program on palliative care is desirable.

BACKGROUND AND OBJECTIVES: There are few epidemiological studies in mechanical ventilation, and the aim of the study is to show how this procedure is being used in Brazil. METHODS: A 1-day point prevalence study was performed in 40 ICUs, with 390 patients; 217 of these patients were in mechanical ventilation. The results evaluated were the characteristics of ventilated patients, their distribution in Brazil, the mechanical ventilation's causes, the main ventilatory modes, the more important ventilators settings, and the weaning stage of mechanical ventilation. RESULTS: The median age of the ventilated patients was 66 years old. The median APACHE II was 20, while the median time of mechanical ventilation was 11 days. Acute respiratory failure occurred in 71% of the patients, coma in 21.2%, acute exacerbation of chronic respiratory failure in 5.5%, and the neuromuscular disease in 2.3%. The volume-controlled ventilation (VCV) (30%), the pressure support ventilation (PSV) (29.5%), and the pressure-controlled ventilation (PCV) (18%) were the ventilatory modes most used; the PSV had been the main mode in weaning (63.5%). The median of tidal volume (8 mL/kg) was higher in VCV. The median of maximal inspiratory pression (30 cmH2O) and the median of positive end-expiration pressure (PEEP) (8 cmH2O) were higher in PCV. CONCLUSIONS: The predominance of ventilated patients in ICUs was marked by clinical severity of them, and a longer hospital stay time; acute respiratory failure was the principal mechanical ventilation cause; VCV and PSV ventilated more patients, with PSV being more used in weaning patients.
