摘要：
Cell or tissue permeability to electrical signals can be used to determine the depth of anesthesia of a patient. A method and device is presented to measure, record and control the effects of anesthesia or analgesics on humans and/or animals. Based on impedance values of tissues measured at single, multiple, or a domain of frequencies, the system detects tissue permeability alterations as determined by electromagnetic, impedance, and/or dielectric spectroscopy. The system measures the permeability of tissues to electrical signals and correlates these values to the depth of anesthesia or sedation level of a certain tissue or individual. This method and device can be used to measure the effects of anesthesia or analgesic for either local or systemic administration.
