It is possible for trauma to cause clotting problems even without resuscitation efforts.Damage control resuscitation is based on three principles:

permissive hypotension: tries to balance temporary suboptimal perfusion to organs with conditions for halting blood loss by setting a goal of 90 mmHg systolic blood pressure 
hemostatic resuscitation: restoring blood volume in ways (with whole blood or equivalent) that interfere minimally with the natural process of stopping bleeding. damage control surgery. Signs and symptoms
Symptoms of hypovolemic shock can be related to volume depletion, electrolyte imbalances, or acid–base disorders that accompany hypovolemic shock.Patients with volume depletion may complain of thirst, muscle cramps, and/or orthostatic hypotension. Severe hypovolemic shock can result in mesenteric and coronary ischemia that can cause abdominal or chest pain. Agitation, lethargy, or confusion may characterize brain mal-perfusion.Dry mucous membranes, decreased skin turgor, low jugular venous distention, tachycardia, and hypotension can be seen along with decreased urinary output. Patients in shock can appear cold, clammy, and cyanotic.Early signs and symptoms include tachycardia given rise to by catecholamine release; skin pallor due to vasoconstriction triggered by catecholamine release; hypotension followed by hypovolaemia and perhaps arising after myocardial insufficiency; and confusion, aggression, drowsiness and coma caused by cerebral hypoxia or acidosis. Tachypnoea owing to hypoxia and acidosis, general weakness caused by hypoxia and acidosis, thirst induced by hypovolaemia, and oliguria caused by reduced perfusion may also arise.Abnormal growing central venous pressure indicates either hypotension or hypovolemia.
Tachycardia accompanied by declined urine outflow implies either tension pneumothorax, cardiac tamponade or cardiac failure which is thought secondary to cardiac contusion or ischaemic heart disease. Echocardiography in such case may be helpful to distinguish cardiac failure from other diseases. Cardiac failure manifests a weak contractibility myocardium; treatment with an inotropic drug such as dobutamine may be appropriate. Cause
The annual incidence of shock of any etiology is 0.3 to 0.7 per 1000, with hemorrhagic shock being most common in the intensive care unit. Hypovolemic shock is the most common type of shock in children, most commonly due to diarrheal illness in the developing world.Hypovolemic shock occurs as a result of either blood loss or extracellular fluid loss. Blood loss
Hemorrhagic shock is hypovolemic shock from blood loss. Traumatic injury is by far the most common cause of hemorrhagic shock, particularly blunt and penetrating trauma, followed by upper and lower gastrointestinal sources, such as gastrointestinal (GI) bleed. Other causes of hemorrhagic shock include bleed from an ectopic pregnancy, bleeding from surgical intervention, vaginal bleeding, and splenic rupture.Obstetrical, vascular, iatrogenic, and even urological sources have all been described. Bleeding may be either external or internal. A substantial amount of blood loss to the point of hemodynamic compromise may occur in the chest, abdomen, or the retroperitoneum.
