Overview :
Cauchy et al
proposed a new classification of frostbite lesions involving the extremities.
Findings after initial rewarming and on day 2 after admission may be helpful in
management planning. The authors are from Chamonix,
France.
Parameters:
(1) initial
lesion on day 0 after rapid rewarming
(2) radiotracer
uptake in bone scan on day 2
(3) skin
blisters on day 2

Outcome |
|
1 |
no
amputation and no long term sequelae |
|
2 |
some
tissue amputation with fingernail sequelae |
|
3 |
bone
amputation in digit; functional sequelae |
|
4 |
more
extensive amputation; may suffer thrombosis; may become septic; may have
systemic illness; functional
sequelae |
