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 multiple organ ...
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.
Volume contraction of extracellular fluid is directly coupled to and almost proportional to volume contraction of blood plasma, which is termed hypovolemia. [2] [3] Thus, it primarily affects the circulatory system, potentially causing hypovolemic shock.
Shock is divided into four main types based on the underlying cause: hypovolemic, cardiogenic, obstructive, and distributive shock. [2] Hypovolemic shock, also known as low volume shock, may be from bleeding, diarrhea, or vomiting. [1] Cardiogenic shock may be due to a heart attack or cardiac contusion. [1]
Adrenal crisis, also known as Addisonian crisis or acute adrenal insufficiency, is a life-threatening complication of adrenal insufficiency. Hypotension and hypovolemic shock are the main symptoms of an adrenal crisis.
Hypovolemic shock is shock due to inadequate blood volume. [1] A common cause of hypovolemic shock related to surgery is blood loss, but some other causes include by vomiting, diarrhea, or inflammation causing body fluid to leak out of the blood vessels and settle into tissue or lymphatics.
Ringer's lactate solution is commonly used for fluid resuscitation after blood loss due to trauma, or surgery. [9] [10]It is extensively used in aggressive volume resuscitation, e.g. for patients with pancreatitis, hemorrhagic shock or major burn injuries. [10]
NS is used frequently in intravenous drips (IVs) for patients who cannot take fluids orally and have developed or are in danger of developing dehydration or hypovolemia. NS is typically the first fluid used when hypovolemia is severe enough to threaten the adequacy of blood circulation, and has long been believed to be the safest fluid to give ...
