Use of Nitroglycerine to Improve Signs of Poor Peripheral Perfusion in Patients With Traumatic Hemorrhagic Shock

Hemorrhagic shock is a pathologic state in which intravascular volume and oxygen delivery are impaired. During circulatory failure associated with hypovolemia and low cardiac output, redistribution of blood flow caused by increased vasoconstriction results in decreased perfusion of the skin. Skin temperature and capillary refill time has been advocated as a measure of peripheral perfusion.
