Summary
Until today there is no standard-monitoring to specifically reflect the analgesic component
of general anesthesia. Quality and safety of general anesthesia are of major clinical
importance and can be improved by limiting the administration of opioid analgesics to the
minimum dose needed. This study therefore examines the quality of three different monitoring
techniques (PhysioDoloris, MetroDoloris, Lille, France, SPI (Surgical Plethysmographic
Index), GE Healthcare, Helsinki, Finland and AlgiScan, IDMed, Marseille, France) in assessing
the level of analgesia during general anesthesia. Therefore a standardized painful stimulus
is applied under different levels of analgesic drugs. The monitor's indices are compared to
clinical signs such as an increase in heart rate and blood pressure.
