1. Effects of catecholamines on volemic replacement with saline solution and the impact on heart rate variability in rabbits subjected to hemorrhage. A study by spectral analysis
PURPOSE: To verify the effects of different catecholamines on volemic expansion and on the autonomic nervous system in rabbits that were subjected to hemorrhage.METHODS: Twenty four rabbits subjected to hemorrhage (with a 25% loss of blood volume) and were randomly divided into four experimental groups: 1) HEMO Group underwent replacement with their own bloo

2. Inflammatory mediators and sequencial organ failure assessment score - SOFA outcomes after conventional ultrafiltration during circulatory bypass in patients underwent coronary artery bypass graft / Influencia da ultrafiltração na remoção de mediadores inflamatorios durante circulação extracorporea e alterações da função organica monitorada pelo "Sequencial Organ Failure Assessment Score - SOFA" em pacientes submetidos a revascularização do miocar
Objective: To investigate the effectiveness of ultrafiltration in removing inflammatory mediators released by cardiopulmonary bypass and to correlate ultrafiltration with alterations in organic function according to the Sequential Organ Failure Assessment Score. Methods: Forty patients were included and randomized into two groups: "no ultrafiltration" (n=20;

3. Evolution of central venous saturation oxygen, lactate and base deficit in severe sepsis and septic shock patients submitted to early volemic resuscitation / Evolução dos valores de saturação venosa central de oxigênio, lactato e déficit de base em cães com sepse grave e choque séptico submetidos à ressuscitação volêmica precoce
Sepsis is a clinical syndrome that causes changes in the microcirculation characteristics, making the assessment of tissue perfusion. In humans, studies have shown the importance of establishing a therapy based on routine clinical assessments and the variables of oxygenation and tissue perfusion and central venous saturation of oxygen, lactate and base defic

4. Comparison between two techniques of volemic expansion during surgery to total hip arthroplasty: hydroxyethyl starch (130/0,4) and lactateds Ringer solutions. Study prospective, randomized / Estudo prospectivo randomizado comparando duas técnicas de expansão volêmica em cirurgia de artroplastia total de quadril: hidroxietilamido (130/0,4) e Ringer lactato
Introduction: Hydroxyethyl starches (HES) are considered effective plasma expanders in patients undergoing major surgeries. However, the clinical use of HES is limited mainly by their affection of hemostasis, detectable by impaired platelet function and altered coagulation. The extent of such alteration has classically been related to the molecular weight or

5. Comparison of microcirculatory effects between vasopressine and noradrenalin associates to volemic ressuscitation during hemorrhagic shock. Experimental study in hamster / Comparação dos efeitos microcirculatórios da vasopressina e da noradrenalina associadas à reposição volêmica durante o choque hemorrágico. Estudo experimental em hamster
Objetivos: Este trabalho teve como objetivos avaliar in vivo os efeitos microcirculatórios e a sobrevida de animais submetidos ao choque hemorrágico tratados com vasopressina e noradrenalina associadas à reposição volêmica com solução de NaCl 0,9% . Desenho do estudo: Estudo prospectivo, randomizado, controlado, intervencionista em modelo animal. Mat

6. Hemodynamics effects of volemic replacement with normal saline hypertonic hydroxyethil starch solution : experimental study in hypovolemics dog / Efeitos hemodinamicos da reposição volemica com solução de hidroxil-etil amido hipertonico : estudo experimental em cães hipovolemicos
Background and Objectives: Several solutions may be employed for the treatment of hypovolemia. Among the various solutions used, the most common are crystalloids and colloids. In the 80s, the use of hypertonic saline solutions was studied for small-volume fluid replacement. Subsequently, these hypertonic solutions were associated with colloid solutions produ

7. A distensÃo mecÃnica atrial direita diminui a complacÃncia gÃstrica em ratos normovolÃmicos anestesiados / The Decreases of Gastric compliance Due do to Rigth Atrial Distension in Normovolemics Anesthetized Rats
GraÃa et al. (2002) observou em ratos que a hipervolemia aumenta o tÃnus gÃstrico, enquanto a hipovolemia o diminuÃa. Resolvemos estudar o efeito do estiramento cardÃaco sobre o tÃnus gÃstrico e os mecanismos neurais envolvidos. Metodologia: Ratos albinos machos (n=82, ~320g), anestesiados, com vasos cervicais canulados para registros hemodinÃmicos e

8. Isquemia e reperfusão hepatica total em condições de normalidade e sob estado de choque hemorragico controlado : efeitos no sequestro de neutrofilos no ileo terminal e colon sigmoide do rato
The trauma is one of the main causes of death on the population, ranking the third place if considered all ages and the first up to the age of 44. Among these causes, the liver represents the most frequently hit organ in abdominal trauma.This way, the patients victims of severe hepatic injuries, due to hemorrhagic shock, can evolve to a systemic inflammatory
