Determination of the anesthetic state of a patient
First Claim
1. A method for determining the anesthetic state of a patient, the method comprising the steps of:
- establishing values for a set of diagnostic indices, the set including at least two diagnostic indices of which a first diagnostic index is indicative of the hypnotic level in a patient and a second diagnostic index of the level of analgesia in the patient, whereby at least two index values are obtained; and
employing the at least two index values for indicating the anesthetic state of the patient.

Abstract
The invention relates to the determination of the anesthetic state of a patient. In order to achieve a mechanism that enables establishment and maintenance of balanced anesthesia, values are established for a set of diagnostic indices. The set includes at least two diagnostic indices of which a first diagnostic index is indicative of the level of hypnosis and a second diagnostic index of the level of nociception in the patient. The combination of the at least two index values obtained is employed for indicating the anesthetic state of the patient. The combination of the at least two index values may further be employed to control the administration of drugs to the patient.
