The mean arterial pressure, which represents the perfusion pressure of all organs (except the heart), might serve as a target that physicians must achieve by early
fluid administration. A critical element of the resuscitation of the patient with hemorrhagic shock is to prevent a potential increase in bleeding by a resuscitative manoeuvre that is overly aggressive. Fluid resuscitation may promote
coagulopathy by diluting coagulation factors and favoring hypothermia. Moreover, an excessive level of mean arterial pressure (MAP) can favor the bleeding by preventing clot formation. Two concepts have emerged in past years: the
concept of “low-volume resuscitation” and the concept of
“hypotensive resuscitation.” Often, these two concepts are merged. Several experimental studies have suggested that the limited administration of fluids associated with a low blood pressure level as an end point may limit bleeding
without the related increased risk of death [1 9]
