The drugs are short acting because they are quickly re- distributed from the brain to highly perfused organs (eg, heart, GENERAL ANESTHESIA liver, kidneys) and muscles, and then to fatty tissues.

CNS depression is determined by the concentration distant from the area to be anesthetized. Field block anesthesia involves injecting the anesthetic on the rate at which the drug is transported from the alveoli solution around the area to be anesthetized. Spinal anesthesia involves injecting the anesthetic the CNS, redistributed by the blood to other body tissues, and agent into the cerebrospinal ﬂuid, usually in the lum- eliminated by the lungs.

Abnormal movements provide abnormal sure across joints and allows weight bearing, sensory feedback, which reinforces limited, for example, on the arm through the extended nonselective, abnormal movement. They use pressure or support on key proximal limb or Brunnstrom trunk points to inhibit or facilitate movement. For example, the hemiplegic Specific techniques are recommended for each patient with flexor spasticity of an arm that of the 6 stages of recovery that emerge: (1) flac- rides up during walking is trained to bend for- cidity, (2) limb synergies with onset of spastic- ward in a chair with the arm hanging down.
