Abstract:
A method for intentionally inducing whole-body hyperthermia or hypothermia while protecting the central nervous system in a patient for medical treatment, comprising:immersing the patient in a fluid bath with a temperature greater than or less than normal body temperature to thereby increase or decrease the patient's body temperature; circulating the patient's cerebral spinal fluid comprising steps of: withdrawing the patient's cerebral spinal fluid; introducing a membrane stabilizing agent into the cerebral spinal fluid; controlling the temperature and chemical characteristics of the withdrawn cerebral spinal fluid, reintroducing the cerebral spinal fluid into the patient; circulating the patient's central nervous system blood comprising steps of: withdrawing the blood from the patient's central nervous system; controlling the temperature and chemical characteristics of the withdrawn central nervous system blood; oxygenating the central nervous system blood, and reintroduces the central nervous system blood into the patient; circulating the remaining blood in the patient's body comprising steps of: withdrawing the blood from the remainder of the patient's body; controlling the temperature and chemical characteristics of the withdrawn body blood; oxygenating the body blood; and reintroducing the body blood into the patient; and returning the patient's body temperature to a normal level after a predetermined time.
