Gangrene
By Nolan Quinn and Maddy
Sorel
What


Gangrene=Death and
decay of body tissue
caused by insufficient
blood supply, Usually
following disease,
infection, injury, blood
vessel disease, or
surgery.
Thrive where there is no
oxygen
Types and Where


Dry Gangrene= affects bodies
extremities
1. arteries get blocked= tissue
slowly dies
2. Affected body parts feel cold and
turn dark, it will dry and
wither/eventually falling off
3. Mostly affects extremities such as
fingers and toes
Wet Gangrene= occurs with injury and
infection
1. Injury restricts blood flow to the
certain area
2. Blood cant flow to tissue so can’t
fight infection= infection sets in,
3. Swelling from infection= even less
blood flow= fast spreading
gangrene=life threatening
4. Become swollen, discolored, and
smelly.

Necrotising Fasciitis= Caused by
serious bacterial infection, sometimes
referred to as flesh-eating bacteria




Bacteria enters a cut and spreads
quickly, releases toxins
Block blood to surrounding skin,
causing death of skin
Mostly attacks people with very low
immune systems
Gas Gangrene= just like Necrotising
except develops deep in body ex)
muscles (mostly from surgical wounds)


Releases gasses and toxins to kill
living tissue, then spreads
Loves to be in low oxygen areas
Types/Where continued

Internal
Gangrene=affects
internal organs
1.
2.
3.
Blood flow to internal organ
is blocked
Happens when
complications occur with a
hernia
Usually affects organs such
as intestines, gallbladder,
or appendix.
How
Occurs when there is dead tissue
 On toes, fingers and limbs
 It spreads by killing off more tissue
 It spread extremely fast usually must
amputate

Symtoms




Three types: Dry, Wet, Gas
Dry: affected area-cold numb red to brown to black and
shriveled
Wet: swollen- decays, extremely painful, smelly, oozing
then turns black and affected person develops a fever
Gas: brownish red discharge oozes, Gas produced by
Clostridia may produce a crackling sensation, painful,
then high fever and increase in heart rate
Where
Toes, fingers, limbs
 Internal organs
 Feet legs (most common)

Civil War
Graphs/Statistics

Top countries with
condtions: Egypt,
U.S.A, Gerogia,
Nepal, Canada
Treatment
Antibiotics are available at hospitals
 Administration of pressured oxygen
 “Maggot Therapy” (popular in WW1)
 Amputation
 Removal of affected area

Warning
