Hypovolemic Shock

By Dr. Ahmed Hafez

Background 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.  Most often, hypovolemic shock is secondary to rapid blood loss (hemorrhagic shock). Acute external blood loss secondary to penetrating trauma and

Cardiogenic shock

By Dr. Ahmed Hafez

Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body’s organs due to the dysfunction of the heart. Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness. People may also have a severely low blood pressure and heart rate. Causes of cardiogenic shock include cardiomyopathic, arrhythmic, and mechanical. Cardiogenic shock is most commonly precipitated by a heart attack. Treatment of cardiogenic shock depends on the cause with the initial goals to improve blood flow to the body. If cardiogenic shock is due to a heart
