ON THE COVER:
The best proven approach to predicting response to surgical stimulation under general anesthesia is use of pharmacokinetic–pharmacodynamic (PK/PD) models for opioids and hypnotics. An alternative approach is based on the individual assessment of a physiologic reflex evoked by a standardized noxious test. In this issue of Anesthesiology, Guglielminotti et al. demonstrate that the pupillary dilatation reflex amplitude is as accurate as use of PK/PD models for predicting movement in response to surgical stimulation. In an accompanying Editorial View, Larson and Gupta tell us how pupillometry may bring us a step closer to tailoring anesthesia in real-time to meet the needs of each individual patient.
