1. Comparison of vena cava distensibility index and pulse pressure variation for the evaluation of intravascular volume in critically ill children
Abstract Objective: In this study, the authors aimed to evaluate the effectiveness of the vena cava distensibility index and pulse pressure variation as dynamic parameters for estimating intravascular volume in critically ill children. Methods: Patients aged 1 month to 18 years, who were hospitalized in the present study’s pediatric intensive care unit,

2. Is it Possible to Predict Massive Bleeding in Nulliparous Women with Placenta Previa?
Abstract Objective We evaluated risk factors to determine if there were specific risk factors that could predict massive bleeding in nulliparous women with placenta previa. Methods The participants were classified into two groups. Women with a calculated blood loss ≥ 1,000mL were included in the massive bleeding group. Women without any signs or sympto

3. Drug-induced nephrotoxicity
RESUMO A lesão renal aguda é um diagnóstico muito comum, presente em até 60% dos pacientes críticos, e sua terceira maior causa é a toxicidade de medicamentos. A nefrotoxicidade pode ser definida como qualquer lesão renal causada por medicamentos, direta ou indiretamente, tendo a insuficiência renal aguda, tubulopatias e glomerulopatias como apresent

4. Importance of preoperative guided ultrasound in patients with femoral fracture: case report
Resumo Objetivo: Exemplificar o papel do emprego da ultrassonografia à beira do leito pelo anestesiologista e oferecer uma abordagem individualizada para a condição específica do paciente, sem que haja postergação desnecessária de correções cirúrgicas de fraturas de fêmur em idosos. Relato do caso: Paciente feminina, 86 anos, hipertensa, vítima

5. Short-term effects of stored homologous red blood cell transfusion on cardiorespiratory function and inflammation: an experimental study in a hypovolemia model
The pathophysiological mechanisms associated with the effects of red blood cell (RBC) transfusion on cardiopulmonary function and inflammation are unclear. We developed an experimental model of homologous 14-days stored RBC transfusion in hypovolemic swine to evaluate the short-term effects of transfusion on cardiopulmonary system and inflammation. Sixteen h

6. Interaction between thermoregulation and osmoregulation in domestic animals
ABSTRACT The ability to maintain core temperature as well as volume and composition of body fluids within narrow ranges is a major characteristic of mammals. Yet, the ability to maintain a stable core temperature often relies on physiological responses that perturb the stability of body fluids. A common thermoregulatory mechanism that affects body fluid home

7. Eisenmenger Syndrome in Pregnancy
Abstract Eisenmenger syndrome is very rare in pregnant women. Debates remain concerning the management of Eisenmenger syndrome in this patient population and the prognosis is unclear in terms of maternal and fetoneonatal outcomes. Epidural analgesia is preferred for Cesarean section as it alleviates perioperative pain and reduces the pulmonary and systemic v

8. Pulse pressure variation and stroke volume variation under different inhaled concentrations of isoflurane, sevoflurane and desflurane in pigs undergoing hemorrhage
OBJECTIVES: Inhalant anesthesia induces dose-dependent cardiovascular depression, but whether fluid responsiveness is differentially influenced by the inhalant agent and plasma volemia remains unknown. The aim of this study was to compare the effects of isoflurane, sevoflurane and desflurane on pulse pressure variation and stroke volume variation in pigs un

9. Pulse Pressure Variation Patterns in a Swine Model of Hypovolemia under Spontaneous Breathing vs. Invasive Positive-Pressure Ventilation
RESUMO OBJETIVO: Este estudo foi realizado para obtenção do título de Mestre em Medicina, Novembro/2012-Julho/2013. A melhoria do débito cardíaco após a administração de fluidos é conhecida como a capacidade de resposta do fluido. Um parâmetro confiável para sua avaliação é a variação da pressão de pulso, cuja utilidade na previsão da capa

10. Fluid volume kinetics of dilutional hyponatremia; a shock syndrome revisited
OBJECTIVE: To evaluate whether the pathophysiology of shock syndromes can be better understood by comparing central hemodynamics with kinetic data on fluid and electrolyte shifts. METHODS: We studied the dilutional hyponatremic shock that developed in response to overhydration with electrolyte-free irrigating fluid - the so-called ‘transurethral resecti

11. Acute kidney injury in a tropical country: a cohort study of 253 patients in an infectious diseases intensive care unit
Introduction: Acute kidney injury (AKI) is a frequent and potentially fatal complication in infectious diseases. The aim of this study was to investigate the clinical aspects of AKI associated with infectious diseases and the factors associated with mortality. Methods: This retrospective study was conducted in patients with AKI who were admitted to the in

12. Critical evaluation of justifications for the transfusion of red blood cells: the reality of a government emergency hospital
BACKGROUND: Blood products and derivatives are indispensable resources in medical therapies. However, it is important to note that the number of donations is far from ideal. Despite constant campaign efforts, a deficit of 1 million units is expected by 2030. OBJECTIVES: To determine the adequacy of the indications for red blood cell transfusion in an eme
