Q

Third-degree burns or “full-thickness burns”

wreck the epidermis, the whole dermis, and sometimes the deeper layers of tissue. They do not hurt because of the loss of the nerve endings in the burned tissue.

Q

What’s the acid burns complications and how it penetrate to soft tissues ?

A

create crust around affected area, thus creating barrier for acid itself to penetrate tissue even further .

Q

Why in third degree paresthesia or anesthesia Therefore pain is generally not a significant problem. Hemorrhage is usually not prsent occur ?

A

Cause burns reach the subcutaneous tissue and the nerve damaged and blood vessels cauterized .

Bleeding may occur during 3 week of healing

16
Q

proliferation and scar formation can create lip adhering to alveolar process and microstomia , commissure deformation and deformation of oral cavity in general

During which phase of healing ?

A

During secondary intention healing process after The necrotic tissue, known as eschar, becomes charred or crusty in appearance and begins to separate from the surrounding viable tissue.

During this period of time intraoral appliances should be considered

17
Q

What’s the wound cleaning agent in chemical burns ?

A

antidote or antagonist of primary cause of burn

Acid burn should be cleaned and washed with weak ,water diluted alkaline solution

alkaline burns should be cleaned with weak acid solutions like water diluted vinegar and lemon juice

18
Q

first degree burns should be treated with what ?


A

with apical creams and gels, like creams containing pantothenic acid (bepanten, panthenol) and cold dressings

19
Q

second degree burns should be treated with ?

A

thoroughly cleaned and dressed with antiseptic gauzes


20
Q

during third and fourth degree burns treatment ?

A

surgical debridement , necrotomy and skin grafting can be considered in addition

21
Q

Frostbites


A

thermal injuries gotten from low temperature and freezing of the skin.

Blood viscosity changes under low temperatures, becomes thick, thus sustained low temperatures even below zero degree can cause soft tissue damage

22
Q

What’s frostnip ?

A

Mild form of frostbite : Continued cold exposure leads to numbness in the affected area. As your skin warms, you may feel pain and tingling. Frostnip doesn’t cause permanent skin damage.

23
Q

What’s Superficial frostbite ?

A

causes slight changes in skin color. The skin may begin to feel warm — a sign of serious skin involvement.

If you treat frostbite with rewarming at this stage, the surface of the skin may appear mottled.

And you may notice stinging, burning and swelling. A fluid-filled blister may appear 12 to 36 hours after rewarming the skin.

24
Q

Deep (severe) frostbite ?

A

As frostbite progresses, it affects all layers of the skin as well as the tissues that lie below.

The skin turns white or blue-gray and you lose all sensation of cold, pain or discomfort in the area. Joints or muscles may stop working.

25
Q

Large blisters form 24 to 48 hours after rewarming. The tissue turns black and hard as it dies. Which stage of frostbite ?

A

Deep ( severe )

26
Q

What we observe during frostbite ?

A

cyanous , rigid, ischemic soft tissue.

First hours primary injuries may not be as visible but

27
Q

demarcation line becomes apparent and visible. Non-Viable tissue separates , becomes darker and undergoes necrosis. In which stage we start to observe that in frostbite ?

A

during first 3-5 days

28
Q

Rubbing alcoholic solutions doesn’t affect positively on frostbites. During which degrees ?

A

second , third and fourth degree frostbites can even worsen the situation.

29
Q

What we use instead of alcohol solutions ?

A

Warm baths and warm dressing are better solutions. 



30
Q

Why the m doctor may wait 1 to 3 months before removing damaged tissue ?

A

To better distinguish between healthy and dead tissue,

31
Q

How Whirlpool therapy or physical therapy help ?

A

Soaking in a whirlpool bath (hydrotherapy) can aid healing by keeping skin clean and naturally removing dead tissue.

32
Q

Which medication frosbites doctors give ?

A
  1. Infection-fighting drugs. If the skin or blisters appear infected, your doctor may prescribe oral antibiotics.
  2. Oral pain medicine. Because the rewarming process can be painful, your doctor will likely give you a drug to ease the pain.

Clot-busting drugs. You may receive an intravenous (IV) injection of a drug that helps restore blood flow (thrombolytic), such as tissue plasminogen activator (TPA).

33
Q

Which drugs lower amputation risk in frostbites ?

A

Clot-busting drugs TPA

BUT give them only at first 24hr to avoid bleeding

34
Q

Which treatment options available ?

A
  1. Surgery. People who have experienced severe frostbite may in time need surgery or amputation to remove dead or decaying tissue.
  2. Hyperbaric oxygen therapy. Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized room. Some patients show improved symptoms after this therapy.
35
Q

What’s Radiological burns ?


A

are an effect of ionizing radiation on soft tissue . This type of injuries are most common during tumors’ radiological treatment and during wartime as an outcome of atomic bomb explosions.

36
Q

Radiation burns symptoms ?

A

Reddening of white skin or darkening of skin that is black or brown.
Itchy skin.
Dry and peeling skin.
Swelling.
Blistering.


37
Q

What’s radiation therapy ?

A
