1. Impact of Vacuum-Assisted Venous Drainage on Forward Flow in Simulated Pediatric Cardiopulmonary Bypass Circuits Utilizing a Centrifugal Arterial Pump Head
Abstract Objective: To analyze the impact of vacuum-assisted venous drainage (VAVD) on arterial pump flow in a simulated pediatric cardiopulmonary bypass circuit utilizing a centrifugal pump (CP) with an external arterial filter. Methods: The simulation circuit consisted of a Quadrox-I Pediatric oxygenator, a Rotaflow CP (Maquet Cardiopulmonary AG, Rastatt

2. 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

3. Animal model of rapid crystalloid infusion in rats
PURPOSE: To describe an animal model of rapid intravenous infusion with different volumes of crystalloid and discuss the clinical findings. METHODS: Fifty six male Wistar rats were used, divided randomly in seven groups (n = 8). The rats of groups 1 to 6 received lactated Ringer´s solution intravenously, in the rate of 25 ml/min, with different volumes prop

4. Intraoperative fluid management in open gastrointestinal surgery: goal-directed versus restrictive
OBJECTIVE: The optimal strategy for fluid management during gastrointestinal surgery remains unclear. Minimizing the variation in arterial pulse pressure, which is induced by mechanical ventilation, is a potential strategy to improve postoperative outcomes. We tested this hypothesis in a prospective, randomized study with lactated Ringer's solution and 6% hy

5. Estudo dos efeitos da solução salina hipertônica e do Ringer lactato sobre a resposta da microcirculação mesentérica e a translocação bacteriana em modelo de obstrução intestinal e isquemia em ratos / Study of the effects of hypertonic saline and lactated Ringer´s solutions on mesenteric microcirculatory response and bacterial translocation in a rat model of intestinal obstruction and ischemia
INTRODUÇÃO: Estudos demonstram que a solução salina hipertônica melhora a hemodinâmica, a microcirculação e modula o sistema imune, atenuando a resposta inflamatória associada ao choque e trauma. Este estudo tem por objetivo avaliar e comparar os efeitos da solução salina hipertônica (NaCl, 7,5%) e do Ringer lactato seguido da ressecção de segm

6. Comparison of the effects of lactated Ringer solution with and without hydroxyethyl starch fluid resuscitation on gut edema during severe splanchnic ischemia
The type of fluid used during resuscitation may have an important impact on tissue edema. We evaluated the impact of two different regimens of fluid resuscitation on hemodynamics and on lung and intestinal edema during splanchnic hypoperfusion in rabbits. The study included 16 female New Zealand rabbits (2.9 to 3.3 kg body weight, aged 8 to 12 months) with s

7. Volume replacement with lactated ringers or 3% hypertonic saline solution during combined experimental hemorrhagic shock and traumatic brain injury / Estudo da reposição volêmica inicial em modelo experimental de choque hemorrágico associado ao traumatismo craniencefálico: comparação entre as soluções de ringer lactado e salina hipertônica 3%
The devastating effects of hypotension on head-trauma-related mortality are well known. This study evaluates the systemic and cerebral hemodynamic responses to volume replacement with 3% hypertonic saline (HSS) or lactated Ringers solution (LR), during the acute phase of hemorrhagic shock (HS) associated with traumatic brain injury (TBI). METHODS: Fifteen mo

8. Hemodiluição normovolêmica aguda: estudo experimental comparativo utilizando amido hidroxietílico a 6% ou solução de Ringer lactato / Acute normovolemic hemodilution: comparative evaluation with hydroxyethyl starch and Lactated Ringers
Normovolemic acute hemodilution is a procedure utilized to decrease the needs of blood transfusion during a variety of surgical procedures. Nevertheless, there are few works that evaluate its pulmonary effects as well as hemodynamic changes by means of echocardiography and tonometric evaluation. Methods: 23 anesthetized pigs (weight 46.6 ± 6.0 kg) were inst

9. Effect of fluoride ions on Ti6Al4V alloy passivation in lactated Ringer's serum
The corrosive behavior of Ti and its alloys in fluoride media is well known. Based on electrochemical studies, this paper describes the effect of fluoride ions on the passive behavior of Ti6Al4V alloy in lactated Ringer's serum. The open circuit potential of the alloy in the serum, which lies in the passive region of TiO2, shifts to more negative values as f

10. 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

11. Reposição volemica no choque por hemorragia incontrolada : estudo experimental
Prehospital guidelines for the treatment of hemorrhagic shock r.ecommend rapid volume resuscitation to normal blood pressure. However, there is eviderice that fluid resuscitation (FR) to normal blood pressure in the setting of uncomtrolledl hemorrhagic shock (UHS) causes increased bleeding, hemodilution and mortality. The purpose of this study was to examine
