hypovolemia represents inadequate circulating plasma volume leading to decreased cardiac preload and thus decreased cardiac output and blood pressure. Many classification schemes have been proposed to categorize hypovolemia based on relative levels of decreased plasma volume. Common causes of hypovolemic shock during the perioperative period include hemorrhage and diuretic use. In general, studies support a conservative hemoglobin goal of about 7 g/dL as compared with a liberal goal of 10 g/dL in hemodynamically stable patients without active cardiac ischemia or risk factors. In patients with large volume blood loss, institutionally approved massive transfusion protocols can help provide blood products quickly. The trauma literature supports a balanced massive transfusion protocol using a 1:1:1 (plasma:platelet:red blood cell) strategy of transfusion.
Hypovolemic shock refers to a medical or surgical condition in which rapid fluid loss results in multiple organ failure due to inadequate circulating volume and subsequent inadequate perfusion.

Endothelium plays a critical role in vascular physiological, pathophysiological, and reparative processes. The functions of the endothelium are highly altered following hypovolemic shock due to ischemia of the endothelial cells and by reperfusion due to resuscitation with fluids. Due to oxygen deprivation, endothelial cell apoptosis is induced following hypovolemic shock
