“Introduction Severe hemorrhage is a major cause of death in the trauma patient. Approximately 45% of pre-hospital deaths and 55% of the deaths after hospital admission for trauma are caused by exsanguination [1]. Trauma related hemorrhage caused by penetrating torso injury EVP4593 datasheet is a quick killer [1, 2]. A study of time to death
from trauma showed that among those who died in the first 24 hours, 35% were pronounced almost dead within the first 15 minutes, thoracic vascular injuries from penetrating mechanisms were the main cause; deaths occurring within the first 16 to 60 minutes showed similar results [2]. Therefore, successful treatment of trauma
related hemorrhagic shock should involve timely control of the bleeding and maintenance of adequate tissue perfusion, especially in penetrating mechanism [3]. The importance of fluid resuscitation to maintain tissue perfusion in hemorrhagic shock has been well established, but the optimal blood pressure capable of providing adequate organ perfusion without augmenting hemorrhage is currently a topic for research [3–9]. Recent clinical studies on permissive hypotension and damage control resuscitation 3-MA cell line aiming at delivering higher ratios of blood products and decreasing crystalloid infusion have led to fewer complications associated with excessive fluids, less coagulopathy and ultimately increased survival [6, 7]. Several investigators demonstrated, in animal models, that permissive hypotension (PH) or hypotensive resuscitation (mean arterial pressure between 50-65 mmhg) resulted in decreased blood loss and ultimately lower mortality in hemorrhagic shock compared to normotensive resuscitation [10–14]. Our group recently demonstrated that enhanced clot formation is one of the mechanisms involved in the reduction of blood loss in hypotensive resuscitated animals [15].
