Comparison between pupillometry and numeric pain rating scale for pain assessments in communicating adult patients in the emergency department

ConclusionsPupillometry does not appear to be an effective tool to evaluate pain in the ED environment. Indeed, too many factors influencing the sympathetic system —and thus the dynamic pupillary measures—are not controllable in the ED.SignificancePupillometry does not appear to be an effective tool to evaluate pain in the ED environment.There are several possible explanations for these negative results. The factors influencing the sympathetic system —and thus the PD fluctuations—are controllable in the postoperative period but not in the ED (e.g. full bladder, hypothermia). In addition, numerous psychological phenomena can impact pupillometry measurements such as emotional reactions or cognitive tasks. These phenomena are particularly diffi cult to control in the ED environment.
