What are the three classes of burns

1st degree burn, 2nd degree, & 3rd degree

83

Describe 1st degree burn

84

Describe 2nd degree burn

Epidermal & upper dermal damage & blisters

85

Describe 3rd degree burn

Entire thickness of skin damaged. Gray-white, cherry red or black coloring. No initial edema or pain(nerve ending damage) & skin grafting needed.

86

Describe the "rule of nines"

  • Used to estimate the volume of fluid loss from burns
  • Divides the body into 11 areas, each accounting for 9% of total body area.
  • Burn patients need thousands of extra food calories daily to replace lost proteins & allow tissue repair.
  • After initial crisis has past- sepsis becomes the main threat.
87

When are burns considered critical?

>25% of the body has 2nd degree burns

88

When are burns considered critical?

>10% of the body has 3rd degree burns

89

When are burns considered critical?

face, hands or feet bear 3rd degree burns
