The leading cause of death from extensive burns is:

First of all, after a large-scale burn, due to the extravasation of a large amount of body fluid beyond the compensatory range of the body, the effective circulating blood volume is sharply reduced, which can lead to hypovolemic shock and death. Secondly, due to the ischemia and hypoxia of internal organs, it causes organ function decline or failure leading to death. At the same time, due to the damage of the barrier protection function after burns, and the wound exudate and a large amount of protein, it is conducive to the growth of bacteria in the wound, causing wound infection, sepsis, bacteremia, etc., resulting in organ failure and death.

Patients with extensive burns should first take a medical history and ask about their pre-injury weight; Perform simple wound cleaning to determine the injury, estimate the area and depth, measure blood pressure, pulse, respiration and body temperature, check for compound injury, poisoning or inhalation injury, and ensure airway patency, analgesia and sedation; Rapid establishment of intravenous access; Blood type, electrolytes, liver function, urea nitrogen, routine, etc. are checked. According to the size and weight of the burn, an anti-shock rehydration plan should be formulated, and a urinary catheter should be placed to pay attention to the presence of hemoglobinuria or hematuria; Oxygen or assisted breathing for those with dyspnea; Antibiotics and tetanus antitoxin.

Sepsis due to infection is the leading cause of death in patients with extensive burns.

At present, in the process of clinical treatment, the treatment rate of patients with large-scale burns is still not very high, mainly because patients with large-scale burns are prone to systemic complications and death. The main causes of death are as follows:

Clause. 1. Shock, in the early stage of burns, is prone to shock, which can lead to death in severe cases.

Clause. 2. Acute renal failure is also easy to cause acute renal failure in the early stage, and anuria can also lead to death.

Clause. 3. Heart failure, for older patients, the early cardiac load increases, and cardiac arrest and death are prone to occur.

Clause. 4. Respiratory failure or dyspnea, for patients with deep burns of the head, face and neck, it is easy to cause dyspnea or respiratory asphyxia and death.

Clause. 5. Death due to the presence of systemic failure, also known as mods.

Clause. Sixth, the whole body is ** infected, and death occurs.

The main cause of death in patients with extensive burns is that a large amount of dehydration and electrolyte imbalance eventually leads to death from heart failure, or there is a large-scale infection, and the wound does not heal**, and finally scurvy causes death.

Large-scale burns are a complex and difficult process, and patients need to pass through many hurdles in the whole process, such as shock, anti-infection, and wound repair, so the course of the disease is relatively long, the time is relatively long, and the patient's hospital stay is long.

In this process, various accidents will occur at any time, which leads to the failure of some multiple organs, which is often life-threatening. Therefore, in the process of **, we must deal with the patient's condition in a timely and active manner according to the changes in the patient's condition at any time.

In the whole process, we should actively anti-shock rehydration, anti-infection, and seal the wound as soon as possible to avoid complications, so as to avoid the death of the patient.

Hello, the main causes of death due to extensive burns are circulatory failure, shock, infection.

The most common cause of death in patients with extensive burns is aHypovolemic shock BAcute respiratory failure cStress ulcer DSepsis eAcid-base imbalance in water electrolytes.

Infection is the leading cause of death, and preventing infection should be the top priority.

Answer] :d burn wound tissue has a large number of bacterial invasion, bacteria invade the blood, release a large number of toxins, and become the first cause of death.

The answer is blind and filial piety] :d

Test Center] burns are the most common cause of death.

Analysis] Infection is a prominent problem in the treatment of burns, if the infection is not controlled, internal organ complications are one after another, and eventually death due to septic shock and multi-organ failure.

Answer: b

The most important feature in the early stage of extensive burns is the exudation of body fluids. The exudation is most acute 2 to 3 hours after injury, peaking at 8 hours and lasting 36 hours48 hours.

Fluid loss shock can occur due to massive exudation in the early stages of burns. Therefore, the greatest danger within 24 hours after injury is positive silver loss shock, and the focus of the early ** banquet is anti-shock.

What to do with patients with severe and extensive burns:

1. First of all, the focus is on saving lives, and the patient's vital signs are checked for inhalation injury, suffocation and other life-threatening conditions.

2. Keep the respiratory tract unobstructed, give sedation and pain relief**.

3. Bandage the wound with accessories or clean clothes and sheets to prevent pollution and damage during the handling of the source.

4. Give rehydration to the patient**, if the infusion conditions are not available at the scene, oral salty drinks can be taken to prevent water poisoning caused by simply giving a large amount of drinking water;

5. Actively send to a nearby hospital**, if you can't be admitted to the hospital within 1 2 hours, you should actively fight shock on the spot**, and then transfer to the hospital to continue after the shock is controlled**.

That's probably it.,It's not easy to sort out.,I've seen a thumbs up and then left....

The mortality rate of large-scale burns is very high, and the initial burn injury is doomed, with easy shock in the first 7 days of burn injury, cardiopulmonary failure or damage in the middle 7 to 14 days, infection and multi-organ failure after 14 days.

There are three main reasons for the very high mortality rate of extensive burns:

1. Inhalation injury. It is common at the scene of a fire, when the patient yells in the fire, he inhales a large amount of dust and heat in his respiratory tract, which will cause serious damage to the respiratory tract, on the one hand, it will cause swelling of the respiratory tract and cause suffocation, on the other hand, it will cause some serious damage to the lung parenchyma, and induce serious infection of the lungs in the later stage.

2. Shock. The large area of burns will form a systemic inflammatory response in the body, and the vascular permeability under the inflammatory response will be very high, and a large amount of fluid in the patient's blood vessels will leak out like tissue, resulting in effective blood volume depletion and severe shock. Then two days after the extensive burn, the patient should do anti-shock**, the shock period is generally 48 hours, if the patient can successfully pass the shock period, he has passed the first hurdle.

3. Infection. is the most common cause of death. Burn patients with particularly large burns, ** is a barrier of the human body against infection, after a large area of burns means that the barrier of the body is removed, severe burns will cause a very big blow to the body's system, the patient's resistance will also decrease, and at the same time there will be a displacement of some flora in the intestines.

In this case, the patient is susceptible to severe infections.

Patients with extensive burns have extensive injuries throughout the body, and many wounds require skin grafting for repair. Although allogeneic skin can play a role in short-term coverage and protection of the wound, the final repair of the wound still depends on autologous**. For a patient with a third-degree burn who persuades 90% of the body surface area to have third-degree burns, it means that the doctor has to use the remaining 10% of the normal ** on his body to find a way to repair 90% of the burned wound on his body, which is very difficult.

Patients often have to perform several or even a dozen surgeries to repair a large part of the wound and get it out of danger, during which time the patient is always at risk of infection. Death can occur once the patient's physical condition deteriorates severely, or the wound is not covered in time resulting in severe wound infection, or inhalation injury leads to severe respiratory infection.

Answer]:b Burn is graded as: Mild burn:

Burns with divination 9 or less; Moderate burns: 10 19 ° burns, 10 less than the culture solution; Severe burns: ° burn area 30 39 °, cheating ° burn area up to 10 19 , or shock has occurred, respiratory burns.
