The annual incidence of shock of any etiology is 0.3 to 0.7 per 1000, with hemorrhagic shock being most common in the intensive care unit. Hypovolemic shock is the most common type of shock in children, most commonly due to diarrheal illness in the developing world. [4]
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1] This may be followed by confusion, unconsciousness, or cardiac arrest, as complications worsen. [1]
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 .
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.
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).
[2] [3] Signs and symptoms often appear soon after the stroke has occurred. [3] If symptoms last less than 24 hours, the stroke is a transient ischemic attack (TIA), also called a mini-stroke. [3] Hemorrhagic stroke may also be associated with a severe headache. [3] The symptoms of stroke can be permanent. [5]
The symptoms of a cerebral contusion depend on the severity of the injury, ranging from minor to severe. Individuals may experience a headache, confusion, sleepiness, dizziness, loss of consciousness, nausea and vomiting, seizures, difficulty with coordination and movement, lightheadedness, tinnitus, and spinning sensations.
Other signs and symptoms include feeling tired, dizziness, and pale skin color. [18] A number of foods and medications can turn the stool either red or black in the absence of bleeding. [2] Bismuth found in many antacids may turn stools black as may activated charcoal. [2]
