OBJECTIVES: This study aimed to assess the short-term respiratory tolerance and haemodynamic efficiency of low-volume resuscitation with hypertonic saline and hydroxyethylstarch (HS/HES) in a pig model of lung contusion and controlled haemorrhagic shock. We hypothesised that a low-volume of HS/HES after haemorrhagic shock didn't impact contused lungs in terms of extravascular lung water 3hours after trauma. METHODS: A lung contusion resulting from blunt chest trauma was induced in 28 anaesthetised female pigs with five bolt shots to the right thoracic cage, followed by haemorrhagic shock and fluid resuscitation...

Uncontrolled inflammatory responses underlie the etiology of acute lung injury and acute distress respiratory syndrome, the most common late complications in trauma, the leading cause of death under the age of 59. Treatment with HTS decreases lung injury in clinical trials, rat models of trauma and hemorrhagic shock and inflammation in lung cell lines, although the mechanisms underlying these responses are still incompletely understood. Transcriptomics (RNaseq), proteomics, and U-(13)C-glucose tracing metabolomics experiments were performed to investigate the mechanisms of cellular responses to HTS treatment in primary small airway epithelial cells in the presence or absence of inflammatory injury mediated by a cocktail of cytokines (10 ng/mL of IFNγ, IL-1β, and TNFα)...

Hypertonic sodium lactate (HTL) expands intravascular volume and may provide an alternative substrate for cellular metabolism in sepsis. We compared the effects of HTL, hypertonic saline (HTS), 0.9% ('normal') saline (NS) and Ringer's lactate (RL) on hemodynamics, sublingual and renal microcirculation, renal, mesenteric and brain perfusion, renal and cerebral metabolism, and survival in anesthetized, mechanically-ventilated, adult female sheep. Animals (7 in each group) were randomized to receive a bolus (over 15-min) of 3 ml/kg 0...

Experimental models of human pathology are useful guides to new approaches towards improving clinical and surgical treatments. A systematic search through PubMed using the syntax (shock) AND (trauma) AND (animal model) AND (cardiovascular) AND ("2010/01/01"[PDat]: "2015/12/31"[PDat]) found 88 articles, which were reduced by manual inspection to 43 entries. These were divided into themes and each theme is subsequently narrated and discussed conjointly. Taken together, these articles indicate that valuable information has been developed over the past 5 years concerning endothelial stability, mesenteric lymph, vascular reactivity, traumatic injuries, burn and sepsis...

Background. Angiotensin 1-7 (Ang1-7) plays an important role in renal circulation. Hemorrhagic shock (HS) may cause kidney circulation disturbance, and this study was designed to investigate the renal blood flow (RBF) response to Ang1-7 after HS. Methods. 27 male Wistar rats were subjected to blood withdrawal to reduce mean arterial pressure (MAP) to 45 mmHg for 45 min. The animals were treated with saline (group 1), Ang1-7 (300 ng·kg(-1) min(-1)), Ang1-7 in hypertonic sodium chloride 7.5% (group 3), and hypertonic solution alone (group 4)...

INTRODUCTION: Fluid resuscitation is an indispensable procedure in the acute management of hemorrhagic shock for restoring tissue perfusion, particularly microcirculation in splanchnic organs. Resuscitation fluids include crystalloids, hypertonic saline (HTS), and synthetic colloids, and their selection affects the recovery of microcirculatory blood flow and reactive oxygen species (ROS) formation, which is often evident in the kidney, following reperfusion. In this study, the effects of acute resuscitation with 0...

Acute lung injury (ALI) is a common complication associated with septic shock that directly influences the prognosis of sepsis patients. Currently, one of the main supportive treatment modalities for septic shock is fluid resuscitation. The use of hypertonic saline (HS: 7.5% NaCl) for fluid resuscitation has been described as a promising therapy in experimental models of sepsis-induced ALI, but it has failed to produce similar results in clinical practice. Thus, we compared experimental timing versus clinical timing effectiveness (i...

Multiple organ dysfunction syndrome (MODS) and nosocomial infection following trauma-hemorrhage are among the most important causes of mortality in hemorrhagic shock patients. Dysregulation of the immune system plays a central role in MODS and a fluid having an immunomodulatory effect could be advantageous in hemorrhagic shock resuscitation. Hypertonic saline (HS) is widely used as a resuscitation fluid in trauma-hemorrhagic patients. Besides having beneficial effects on the hemodynamic parameters, HS has modulatory effects on various functions of immune cells such as degranulation, adhesion molecules and cytokines expression, as well as reactive oxygen species production...

OBJECTIVE: The goal of this study was to investigate the effect of hypertonic saline with 6% Dextran-70 (HSD) resuscitation on organ damage and the resuscitation efficiency of the combination of HSD and lactated ringers (LR) in a model of hemorrhage shock in dogs. METHODS: Beagles were bled to hold their mean arterial pressure (MAP) at 50 ± 5 mmHg for 1 h. After hemorrhage, beagles were divided into three groups (n = 7) to receive pre-hospital resuscitation for 1 h (R1): HSD (4 ml/kg), LR (40 ml/kg), and HSD+LR (a combination of 4 ml/kg HSD and 40 ml/kg LR)...

Intestinal tissue got largely decreased blood supply in uncontrolled hemorrhagic shock, because of limited blood mainly supporting brain, heart, kidney etc. This makes intestine as the primary injury target after uncontrolled hemorrhagic shock. However, limited studies focus on how to protect intestine against hemorrhagic shock. Ringer's solution, pentoxifylline and hypertonic saline are widely used to resuscitate in haemorrhagic shock and sepsis tissue injury. Evidence showed that hydrogen inhibited inflammation and reduced oxidative damage...

Hypertonic saline solutions (HSSs) (7.5%) are useful in the resuscitation of patients with hypovolemic shock because they provide immediate intravascular volume expansion via the delivery of a small volume of fluid, improving cardiac function. However, the effects of using 3% HSS in hypovolemic shock resuscitation are not well known. This study was designed to compare the effects of and complications associated with 3% HSS, 7.5% HSS, and standard fluid in resuscitation. In total, 294 severe trauma patients were enrolled from December 2008 to February 2012 and subjected to a double-blind randomized clinical trial...
