Q

What is the signs and symptoms of inhalation injury below the glottis?

A

Manifests as acute respiratory syndrome
- injury depends on length of exposure to smoke or toxic fumes
- causes inflamed airways with pulmonary edema

Q

What are electrical burns?

A

result form coagulation necrosis caused by intense heat generated from an electrical current. Can potentially cause spine injuries, death, and/or direct damage to nerves and vessels

Q

What are the four phases of a burn injury?

A
  1. prehospital care

Q

What is prehospital care?

A

Removes the person from the source of the burn and stop the process. First stage of a burn injury.
Electrical: you remove pt from contact of source Chemical: you brush solid particle off skin
Small thermal burn: Cover with cool, damp towel
large thermal burn: Watch ABC, do not put body in cool water, will CAUSE shock. remove clothing and wrap in dry sheet
Inhalation injury: observe for signs of respiratory distress and treat quickly

16
Q

What is the emergent phase? Primary concerns?

A

Second phase of a burn injury.
-Period of time required to resolve the immediate problems resulting from burn injury lasting up to 72 hrs
- includes respiratory, cardiovascular systems, wound care, drug therapy, nutritional therapy
PRIMARY CONCERNS: hypovolemic shock and edema

17
Q

What happens during hypovolemic shock?

A

massive shift of fluid out of the blood vessels as a result of increased capillary permeability causing a decrease in osmotic pressure. Blood goes to important organs(brain and heart)

18
Q

What is the normal insensible loss of body fluid per hour?

A

50 ml/ hr
sweating, breathing

19
Q

What is the severely burned patient loss of body fluid per hour?

A

200-400ml/hr

20
Q

What is the complications in the respiratory system in the emergent phase?

A

The main concern is airway management.

complications: upper respiratory tract injury, direct insult at the alveolar level, pneumonia, pulmonary edema

21
Q

What is the complications in the cardiovascular system in the emergent phase?

A

Blood goes to the two most important parts of the body: Brain and heart

complications: arrhythmias, edema, necrosis, ischemia

22
Q

What is the complications in the urinary system in the emergent phase?

A

Decrease blood flow to kidneys causes renal ischema

complications: acute tubular necrosis

23
Q

What consists of wound care in the emergent phase?

A

should be delayed until a patient airway, adequate circulation, and adequate fluid replacement have been established
cleansing: done in hydrotherapy tub, cart shower, shower, or bed
debridement: done in OR and loose necrotic skin is removed

24
Q

How long can can someone stay in an immersion tank? Why?

A

20-30 minutes. Any longer can lead to cross contamination of wounds

25
Q

What is the most important measure to be done as soon as the burn patient is able?

A

range of motion. Must move or it can lead to contractures

26
Q

What immunization is given routinely to all burn patients?

A

tetanus

27
Q

What consists of nutritional therapy in the emergent phase?

A
  • When bowel sounds return, the patient may eat.
  • 5000kcal/day
  • supplements, fluid replacement as needed
28
Q

What is the acute phase in a burn injury?

A
  • Begin with mobilization of extracellular fluid and subsequent diuresis
  • Concluded when the burn area is completely covered by skin grafts or when the wounds are healed
  • Necrotic tissue begins to slough, formation of granulation tissue
  • watch for infections
29
Q

How do you prevent curling ulcers?

A

Feed right when there is bowel sounds

30
Q

What are the three types of excision and grafting in the acute phase?

A
  1. eschar
    - removed from subcutaneous tissue or fascia
  2. cultured epithelial autographs (CEA)
    - grown skin from biopsies obtained from patients own skin
  3. Artificial Skin
    - For life threatening full thickness pr deep partial thickness wounds where conventional autografts is not available or advisable
31
Q

With smoke inhalation injuries, what would you look for when the pt comes to the hospital?

A

Swelling, singed nasal hairs, horse voice

32
Q

How do you prevent contractors in a burn patient?

A

Move as soon as possible and as much as possible. Keep up with ROM

33
Q

If a pt has swelling from burns, what do you do?

A

Elevate limbs

34
Q

What are the priorities when it comes to burns?

A

oxygen and airway

35
Q

How would a burn patient receive medication?

A

Iv route
