Formal theory. Rhabdomyolysis is the rapid destruction of skeletal muscle resulting in leakage into the urine of the muscle protein myoglobin. The reduced circulation, in turn, leads to increased coldness in the hands and feet. PAD is most often the result of fatty deposits that build up in arteries, reducing blood flow and oxygen levels in tissues. In the context of surgery, a local anesthetic creates an absence of pain in a specific location of the body without a loss of consciousness, as opposed to a general anesthetic.When it is used on specific nerve pathways (local anesthetic nerve block), paralysis (loss of muscle power) also can be achieved.
