What the trial is, and whether it could suit you

General anesthesia consists of a combination of hypnotic drugs to achieve unconsciousness and opioid analgesics to ensure antinociception. An alternative approach to the intraoperative administration of high-potency opioids to achieve antinociception during surgery is combining general anesthesia with regional anesthesia. Modern general anesthesia aims to avoid an overdose of opioid analgesics and reduce side effects of opioid administration. Quality and safety of general anesthesia are of major clinical importance and can be improved by adjusting the opioid analgesics to the optimal individual dose needed. In current clinical practice, opioid dosage is usually determined by clinical judgment. However, different monitoring devices estimating the effect of nociception during unconsciousness have become commercially available. One of the most recent commercially available nociception indi
