Implication

Muscle fiber differences in ischemic tolerance are hypothesis-generating; animal data leaves open translation to human tourniquet or shock management.

Structured PICO

P
Population
Feline model (cats)
I
Intervention
2-hour period of hemorrhagic shock or hind limb tourniquet ischemia
C
Comparator
Comparison between soleus ('red') and lateral gastrocnemius ('white') muscles
O
Outcome
Metabolic changes (ATP, CP, glucose, G 6-P, lactate) and resting membrane potentialsurrogate

Red skeletal muscle is more susceptible to metabolic derangement during total ischemia but appears protected during hypovolemia compared to white muscle.
