A system and method for controlling the administration of medication to a patient utilizes adaptive feedback to achieve and maintain a target effect in said patient. A sensor package having one or more sensors is used to sense an attribute of the patient and to provide a parameter indicating the attribute being sensed. A medication delivery controller accepts one or more parameters from the sensor package and uses these parameters to determine the effect of a medication on a patient and the concentration level of medication that will achieve a desired effect. The medication delivery controller controls the medication delivery unit to deliver the medication at a rate determined to achieve said target concentration level of said medication in said patient. If the patient's response to a given medication changes as a result of external stimuli, the medication delivery controller can detect this change and determine a new concentration level of medication which will achieve the desired effect. The medication delivery controller can steer the medication delivery unit to administer an amount of medication to reach this new concentration level.

The method of claim 8, wherein said one or more parameters comprise at least one of the group of blood pressure, heart rate, temperature and EEG parameters. 11. The method of claim 1, wherein said step of determining whether the patient's response to said first concentration level of medication has changed comprises the step of measuring the effect of said first concentration level of medication on said patient and comparing said measured effect to the target effect defined by said patient response profile for said first concentration level. 12. The method of claim 1, wherein said step of computing a second patient response profile comprises the steps of: determining an operating point representing a measured effect of said first concentration level of medication on said patient; and shifting said first patient response profile until said patient response profile intersects said operating point. 13. The method of claim 12, wherein said step of shifting said first patient response profile comprises the step of shifting said first patient response profile vertically or horizontally until said patient response profile intersects said operating point.
