Shock is a medical emergency and requires urgent medical care. If shock is suspected, emergency help should be called immediately. While waiting for medical care, the individual should be, if safe, laid down (except in cases of suspected head or back injuries). The legs should be raised if possible, and the person should be kept warm.
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 ...
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 .
Poor perfusion to organs leads to shock. Due to these similarities, some sources place obstructive shock under the category of cardiogenic shock. [1] [5] However, it is important to distinguish between the two types, because treatment is different. [6] In cardiogenic shock, the problem is in the function of the heart itself.
Surgical shock is a physiologic state of shock which can be related to complications of surgery or the surgery itself. [1] Shock is defined as insufficient perfusion or blood flow to organs and body tissue that causes organ and tissue dysfunction, [2] [1] and can be divided into different types depending on the cause and symptoms. A common type ...
When a patient is in shock, the development of end organ damage is typically due to circulating blood volume or blood pressure that is not high enough to maintain oxygen and nutrient supply to vital organs. Initial treatment is focused on stabilizing the patient. Fluids are given to increase circulating blood volume.
Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
As the energy is applied in a more focused fashion, it requires less energy to cause significant injury. Any body organ, including bone and brain, can be injured and bleed. Bleeding may not be readily apparent; internal organs such as the liver, kidney and spleen may bleed into the abdominal cavity. The only apparent signs may come with blood loss.
