Abstract:
1. A method, comprising the steps of: Administering a plurality of interventional agents to a patient until the patient attains a predetermined plane of anesthesia; Amplifying and digitizing brain waves of the patient before and after the administering step to generate a first set of digital data; Amplifying and digitizing brain waves of the patient during a medical procedure to generate a second set of digital data; Computing separate trajectories for at least two different indices of an anesthetic state of the patient during the medical procedure as a function of a comparison of the first and second sets of digital data, using a microprocessor, the indices including a Depth Index (DI), a Memory Index (MI), and a Pain Index (PI), wherein the DI corresponds to a depth of anesthesia of the patient, the PI corresponds to a sensitivity of the patient to pain and the MI corresponds to an ability of the patient to form and store memories; and Controlling, using the microprocessor, delivery of an amount of at least one of the interventional agents as a function of the trajectories, wherein the interventional agents include at least one of anesthetic, analgesic and amnesic agents corresponding to at least one of the DI, MI, and PI trajectories.
