1. Degree of burn shock

There are many ways to classify burn shock. Paris (1967-1969) divided burn shock into mild, severe, and very severe degrees based on the following 8 factors:

In addition, Paris also mentioned two common symptoms, which are chills and blood thickening.

2. Complications in burn shock

Respiratory failure and alveolar haemorrhage: Acute respiratory failure is common after respiratory burns. The patient has a fresh hemoptysis, moist rales on auscultation and respiratory failure. The chest X-ray shows a faint triangular shape. Acute peptic ulcer perforation: also known as stress ulcer, Curling ulcer, gastrointestinal bleeding or surgical abdominal syndrome due to perforation. Lesions are often in the form of erosive ulcers, maybe 2 or more ulcers, often in the stomach, duodenal bulb. Sometimes there are cases of erosive ulcers of the entire digestive tract. Disseminated intravascular coagulation: This syndrome is both a cause and a consequence of shock. Manifestations of purple extremities, prolonged bleeding time, blood clotting time, increased Howell time, decreased platelets, decreased prothrombin ratio.

Acute renal failure : Manifestations of oliguria or anuria, urea test, blood creatinine increased. Patients may have functional renal failure due to excessive painful stimulation causing reflex constriction of blood vessels => kidney ischemia. Due to excessive plasma leakage, it compresses the glomerular vasculature (expanded Bowman's capsule is filled with plasma, compressing the vasculature). Due to decreased circulating blood volume => decreased blood flow through the kidneys => prolonged low arterial blood pressure, 50% slow blood flow => reduced glomerular filtration rate. Due to physical damage: acute tubular necrosis (consequence of prolonged hypoxia) => organic acute renal failure. Due to hemolysis, free Hb in the blood increases => urine will have HC, Hb-shaped mold => oliguria. If accompanied by metabolic acidosis, it will be dangerous, because free Hb is not easily eliminated from the kidneys, but converted into Hematin hydrochloride => renal tubular obstruction => anuria.

3. Burning shock in special subjects

Elderly people: due to reduced resistance, or comorbidities such as cardiovascular, metabolic, not very active but very serious. Common manifestations such as hypothermia, anemia, cardiovascular disorders, oliguria, anuria, white blood cells are usually not high, blood glucose and blood protein are elevated. Pregnant women: Burn shock has consequences for both mother and fetus. When burns are more than 6% deep, it can cause miscarriage or premature birth. The fetus is also affected by decreased circulating blood volume, homeostasis, increased urea, creatinine .... In pregnant women, burn shock is often more severe, easily converted to asthenic shock and the possibility of death. also higher. Sepsis is usually earlier, maybe the second day after the burn, usually gram (-). Children: May experience shock in a small area: children under 3 years old, may experience shock in an area of ​​3-5%. When the burn area is more than 10%, there is a risk of shock. Usually high fever with increased arterial blood pressure. White blood cells are elevated.

4. Shock in patients with skin burns and respiratory burns

Shock rate increased 3 times. Severe prognosis. The disorders are all more serious: blood loss, blood pressure drop, severe electrolyte disturbances. Respiratory disorders are common.
