摘要： Method for determining the anaesthetic depth of a patient, comprising the repeated administering of sensory stimuli to the patient; the repeated, non-invasive recording of the electrical activity of the patient's brain during a measurement interval following each stimulus; the computation, from a number of measurement intervals, of a representation of the response of a sensory neural pathway to a single stimulus; and the determination of the latencies and amplitudes of maxima and minima in the representation, which are a measure of the anaesthetic depth, wherein the measurement intervals are chosen such that they partially overlap one another. Preferably the length of time between two successive stimuli is a stochastic variable having a negative exponential distribution, the computed representation being the first order kernel.
