Patent ID: 8352023

Claim:
A method, comprising the steps of: administering to a patient a plurality of interventional agents 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; determining, using the microprocessor, a recommended amount of at least one of the interventional agents to be delivered to the patient 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; and outputting the recommended amount of the at least one of the interventional agents to a user for consideration in formulating dosages of the interventional agents to be administered to the patient.
