Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [ 1 ] [ 2 ] It can be caused by severe dehydration or blood loss . [ 3 ] [ 2 ] Hypovolemic shock is a medical emergency ; if left untreated, the insufficient blood flow can cause damage to organs , leading to ...
Untreated hypovolemia or excessive and rapid losses of volume may lead to hypovolemic shock. [7] Signs and symptoms of hypovolemic shock include increased heart rate, low blood pressure, pale or cold skin, and altered mental status. When these signs are seen, immediate action should be taken to restore the lost volume.
Hypovolemic shock is the most common type of shock and is caused by insufficient circulating volume. [6] The most common cause of hypovolemic shock is hemorrhage (internal or external); however, vomiting and diarrhea are more common causes in children. [9]
Up to 30% of these children may develop splenic sequestration crisis with a mortality rate of up to 15%. This crisis occurs when splenic vaso-occlusion causes a large percentage of total blood volume to become trapped within the spleen. Clinical signs include severe, rapid drop in hemoglobin leading to hypovolemic shock and death.
Hypovolemic shock is mainly treated with fluid replacement, as described in the fluids section above. If the hypovolemic shock is caused by a hemorrhage, then the provider should obtain blood type, blood cross match, and coagulation studies (PT, INR, PTT). In hemorrhagic shock, patients should receive blood or blood products if they aren't ...
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation .
[2] [3] Thus, it primarily affects the circulatory system, potentially causing hypovolemic shock. ECF volume contraction or hypovolemia is usually the type of volume contraction of primary concern in emergency, since ECF is approximately half the volume of ICF and is the first to be affected in e.g. bleeding.
Sheehan's syndrome, also known as postpartum pituitary gland necrosis, occurs when the pituitary gland is damaged due to significant blood loss and hypovolemic shock (ischemic necrosis) or stroke, originally described during or after childbirth leading to decreased functioning of the pituitary gland (hypopituitarism).
