CONTEXT Thermodilution, which is considered to be a standard technique for measuring the cardiac output in critically ill patients, is not free from relevant risks. There is a need to find alternative, noninvasive, automatic, simple and accurate methods for monitoring cardiac output at the bedside. OBJECTIVE To compare cardiac output measurements by(More)
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(More)

Trauma is the leading cause of death in people below 45 years-old in Brazil, and responsible for one third of all intensive care unit admissions. The increasing knowledge on ultrasound diagnosis methods and its availability for life-threatening injuries (such as cardiac tamponade and abdominal cavity solid organs rupture leading to hemorrhagic shock)(More)
OBJECTIVES Thermodilution (TD) is the "gold standard method" for hemodynamic monitoring. Some parameters can be measured by Oesophageal Doppler (OD), which is simpler and less invasive. To evaluate the accuracy of OD, we compared this method with TD in measurement of cardiac output (CO). METHODS One hundred and ninety two simultaneous measurements were(More)
OBJECTIVE To evaluate gasometric differences of severe trauma patients requiring intubation in prehospital care. METHODS Patients requiring airway management were submitted to collection of arterial blood samples at the beginning of pre-hospital care and at arrival at the Emergency Room. We analyzed: Glasgow Coma Scale, respiratory rate, arterial pH,(More)
BACKGROUND AND OBJECTIVES Anemia of critical illness is a multifactorial condition caused by blood loss, frequent phlebotomies and inadequate production of red blood cells (RBC). Controversy surrounds the most appropriate hemoglobin concentration "trigger" for transfusion of RBC. We aimed to evaluate transfusion practices in Brazilian ICUs. METHODS A(More)
BACKGROUND Intraoperative fluid therapy guided by mechanical ventilation-induced pulse-pressure variation (PPV) may improve outcomes after major surgery. We tested this hypothesis in a multi-center study. METHODS The patients were included in two periods: a first control period (control group; n = 147) in which intraoperative fluids were given according(More)
Although tetanus can be prevented by appropriate immunization, accidental tetanus continues to occur frequently in underdeveloped and developing countries. Tetanus mortality rates remain high in these areas, and studies regarding the best therapy for tetanus are scarce. Because of the paucity of data on accidental tetanus and the clinical relevance of this(More)
