Abstract:
Objective To study proloning the surviving time limit of servered skeletal muscle through intermittent ischemia Methods We use canine gracilis as experimental object to observe its changes by"4C" (colour,capillary bleeding,contractility and consistency of muscle),succinic,dehydrogenase and electron microscope Result (1) At normal temperature the ischemic time limit of skeletal muscle was 7 hours (2) At low temperature (4℃),the surviving time limit of skeletal muscle was 15 hours.(3) However, intermittent ischemia, the surviving time limit of skeletal muscle was 25 hours. Conclusion Intermittent ischemia can prolong the surviving time limit of skeletal muscle obviously So, intermittent ischemia may be used as a new better method of servered limb perservation
