Overview
qNOX and ANI are two indexes evaluting the analgesia conduction during general anesthesia.
No trials have compared them, so with this trial authors want to explore the correlations between them.
Description
qNOX and ANI are two indexes evaluting the anaglesia conduction during general anesthesia.
Even if the aim is the same (to measure the nociception level) these indexes utilize different algorithm: the qNOX is derived by the electroencephalogrm (EEG), the ANI is derived by heart rate variation.
No trials have compared them, so with this trial authors want to explore the correlations between them, and if altered values of one of them is stronger related to postoperative pain and delirium.
