Exposure to fire and smoke in an enclosed setting, Hoarseness or change in voice, Harsh cough, stridor, Burns to the face, head and neck swelling, inflamed oropharynx.
How do burns affect the airway?
In an inhalational burn, there is direct thermal injury to the airway, and the lung parenchyma is affected as a result of a chemical insult by the reagents found in smoke. Respiratory failure, a known complication of inhalational injury, requires ventilator support as well as extended hospital stay in many cases.
What is an airway burn?
Airway burn of inhalation injury is a non-specific term referring to respiratory tract injury caused by heat, smoke, or irritating chemical substances during inspiration. 8. There may be local thermal exposure due to heat exchange and/or exposure to combustion byproducts (lower respiratory tract).
Which of the following signs and symptoms present in a patient with severe burn would indicate possible smoke inhalation?
Numerous signs and symptoms of smoke inhalation may develop. Symptoms may include cough, shortness of breath, hoarseness, headache, and acute mental status changes. Signs such as soot in airway passages or skin color changes may be useful in determining the degree of injury.
What signs and symptoms indicate that a patient has probably suffered inhalation injury How would the nurse know that the patient needs to be intubated?
A targeted physical examination should evaluate for any signs suggestive of inhalation injury, such as face and neck burns, singed nasal hairs, carbonaceous sputum, soot in the upper airways, voice changes, or wheezing. It is important to note that the absence of these signs does not rule out inhalation injury.
How do you assess airway burns?
Assess for airway stability

Attempt to elicit a response from the patient. Look for signs of airway obstruction (stridor, use of accessory muscles, paradoxical chest movements and see-saw respirations). Listen for any upper-airway noises and breath sounds.
What clients with burns require airway and respiratory support?
Respiratory Damage in Burn Patients
Burn patients with second-degree burns or third-degree burns usually have challenges beyond just the wounds to their skin. They often require respiratory therapy due to lung damage caused by smoke or steam inhalation.
What happens when you inhale heat?
“Hot air may also irritate your airway and lead to a bronchospasm, one of the hallmark symptoms of asthma,” said Geisinger allergist and immunologist Yoon Kim, D.O. “This will cause you to feel short of breath and tightness in your chest, and may make you cough or wheeze.”
What kind of damage do respiratory irritants cause to the airway?
Thus, it causes only mild airway and eye irritation symptoms at low concentrations, and deposits distally in the lung where it hydrolyzes to form hydrochloric acid, leading to epithelial damage and cellular necrosis in the bronchi and small bronchioles, and carbon dioxide [9, 26, 27].
How do burns affect the cardiovascular system?
The initial response to severe burn injury or early shock state is characterized by a decrease in cardiac output and metabolic rate. The reduction in cardiac output is partially due to hypovolemia and reduced venous return.
What are the signs of smoke inhalation?
Symptoms of smoke inhalation include:
- Difficulty breathing.
- Noisy breathing.
- Wheezing.
- Hoarse voice, trouble speaking, or inability to speak in full sentences.
- Cough.
- Dark-colored mucus from the nose or mouth.
- Change in mental state, such as restlessness, agitation, confusion, or sleepiness (lethargy).
What are symptoms of inhalation injuries?
Inhalation Injuries
- Coughing and phlegm.
- A scratchy throat.
- Irritated sinuses.
- Shortness of breath.
- Chest pain or tightness.
- Headaches.
- Stinging eyes.
- A runny nose.
Which complications may be seen in burn patient?
Complications
- Bacterial infection, which may lead to a bloodstream infection (sepsis)
- Fluid loss, including low blood volume (hypovolemia)
- Dangerously low body temperature (hypothermia)
- Breathing problems from the intake of hot air or smoke.
- Scars or ridged areas caused by an overgrowth of scar tissue (keloids)
What are some common complications with inhalation burns?
Most patients do not suffer long-term respiratory impairment following smoke inhalation, however, although rare, residual long-term sequelae may include tracheal stenosis, bronchiectasis, interstitial fibrosis reactive airway disease, and bronchiolitis obliterans. These are usually associated with severe injury.
How are thermal burns caused?
Thermal burns.
These burns are due to heat sources which raise the temperature of the skin and tissues and cause tissue cell death or charring. Hot metals, scalding liquids, steam, and flames, when coming into contact with the skin, can cause thermal burns.
How do you classify a burn?
Burns are classified as first-, second-, third-degree, or fourth-degree depending on how deeply and severely they penetrate the skin’s surface. First-degree (superficial) burns. First-degree burns affect only the outer layer of skin, the epidermis. The burn site is red, painful, dry, and with no blisters.
What type of burn occurs when the patient comes into contact with fire or flames?
Thermal burns are skin injuries caused by excessive heat, typically from contact with hot surfaces, hot liquids, steam, or flame.
What is classified as a major burn?
Description. injury with necrosis to epidermis and dermis resulting from thermal, chemical, electrical, or radiation exposure 1,2,4. moderate to severe burns include 1. second-degree (partial-thickness) burns that. involve >, 5% of total body surface area (TBSA) in patients <, 10 years old or >, 50 years old.
What would cause a lower airway burn upon inhalation?
Chemical Injury to the Lower Airways
Sulfur dioxide is produced by burning rubber and plastic, as well as other gases such as nitrogen dioxide, ammonia and chlorine with strong acids and alkali after combination with water in the respiratory airways and alveoli.
Why would a burn victim be intubated?
Indications for endotracheal intubation (ETI) in trauma patients, which include burn patients, are airway obstruction, hypoventilation, persistent hypoxemia (SaO2 ≤ 90%) despite supplemental oxygen, severe cognitive impairment (Glasgow Coma Scale ≤ 8), cardiac arrest, severe hemorrhagic shock and smoke inhalation.
What type of thermal burn is most commonly associated with inhalation injury?
Flame- Flame burns are often associated with inhalation injury and trauma. It comprises 50% of adult burns and tends to be mostly deep dermal or full-thickness burn.
Can heat make you breathless?
The heat, along with increased pollen levels, often intensifies breathlessness. If you do need to go out, try to avoid the hottest part of the day (usually 11am – 3pm).
Can heat cause shortness of breath?
Hot air can also cause a bronchospasm, causing the airways to contract and causing shortness of breath. The body needs more oxygen to stay cool when it’s hot outside, decreasing lung function, which can result in deep or rapid breathing, a condition known as hyperpnea.
What is the pathophysiology of inhalation burn injuries?
The major pathophysiology seen in the upper airway inhalation injury is induced by microvascular changes from direct thermal injury and chemical irritation6. The heat denatures protein, which subsequently activates the complement cascade causing the release of histamine9,12.
How does burns affect the nervous system?
A burn could affect the nerves of the body if it disrupts or damages the neuropathic system. Most burn injury survivors will report some nerve reactions to a burn, the most common being tingling, numbness, burning, weakness, pain, and sensitivity to touch. Others, however, can’t feel their nerves at all.
What are the three zones of burn injury and what are involved with each?
When the burn occurs, three damage zones are described as local changes in the skin. These regions were first described by Jackson in 1947 [13]. It consists of coagulation (necrosis) zone, stasis (ischemia) zone and the outermost hyperthermia (inflammation) zone (Figure 2).
Why would a burn victim have low blood pressure and high heart rate?
In response to trauma, such as burn wounds or multiple bone breaks, the brain releases adrenaline, which causes the heart to beat faster. To keep up with this pace, the body burns muscle for fuel in a process called catabolism, which saps patients of strength and causes them to lose significant amounts of weight.
Can your lungs burn?
Not only are burn injuries painful and devastating to the body, but they also require extensive treatment by specialists. Lung damage is one serious complication present, along with thermal injuries suffered in a fiery car crash.
Can inhaling smoke cause a sore throat?
Smoke can irritate the eyes and airways, causing coughing, a scratchy throat, and irritated eyes and sinuses.
What happens when a child inhales smoke?
Breathing in hot air, smoke, or chemical fumes can cause irritation or swelling in your child’s airways. Being in or near a fire can cause wheezing and breathing problems. Your child may not notice these problems until several hours later. When your child inhales smoke, harmful toxins may get into your child’s body.
What part of the respiratory anatomy will most likely be injured in a burn patient exposed to flames?
Thermal injury often affects only to the level of the larynx. Chemical toxin/irritants may cause damage to just the airways, just the alveoli, or both.
How are airway burns treated?
Drugs such as heparin sulfate, N-acetylcysteine and albuterol have been proven to greatly help in the treatment of patients with inhalational burns. More research is underway to develop chelating drugs that can scavenge the toxic materials in smoke before they damage the airway.
What is the most immediate serious complication associated with burns?
The use of topical antibacterial agents has reduced the incidence of post-burn infection, but infection remains one of the most serious complications of burns. Burn surgeons often obtain cultures of the burn wound and of sputum and other body secretions, these are examined for signs of infection.
When does a burn need medical attention?
In general, the major issues when treating burns are pain control, preventing infection, and achieving a good cosmetic outcome. If there are signs of skin infection, such as increasing redness, pain, pus-like discharge, or temperature greater than 100.4ºF or 38ºC, you should seek medical attention right away.
When should a burn be seen by a doctor?
You should also seek medical attention if you notice fever, redness, oozing or increasing pain, or if you experience a burn on the feet, hands, groin, face, buttocks or over a major joint. Third- and Fourth-degree Burns: With these types of injuries, emergency medical care is a must.
