Summary

Given the difficulties encountered with subjective pain assessment tools, one of the ideas for reducing the occurrence of insufficient analgesia administration in the emergency department is to find a tool capable of measuring pain without requiring the patient's participation, and which could be integrated into the systematic measurement of the 4 other vitals. An interesting idea is the measurement of pupillary diameter and its reflex variations by a portable pupillometer. Indeed, the diameter of the pupil (DP) reflects the constant interactions between the sympathetic and parasympathetic systems at the level of the iris muscles. Pupillometry measures the change in pupillary diameter and allows the performance of three dynamic tests useful in the assessment of pain.

Conditions

• Pain, Acute

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	pupillometry	Step 1: The triage will be carried out by the nurse. The nurse will then perform a self-assessment of the patient's pain using a simple verbal scale. The nurse will then record the patient's self-assessment of his pain using the numeric scale for pain. Step 2: Immediately after this first assessment, eligible patients will be approached by the study investigator to be included in the study. Step 3: If the patient gives informed consent, the study investigator will perform * The quantification of their anxiety * An assessment of pain by a NeuroLight videopupillometer (iDmed, Marseille, France) using two dynamic tests, the Pupillary Unrest in Ambient Light (PUAL) and the pupillary light reflex. Step 4: One hour after the triage, a second pain assessment will be performed. Step 5: The same pupillometry measurements will be taken immediately after the nurse has assessed the pain.
