- Basic treatment with dopamine antagonist antiemetic medication (metoclopramide (T1/2 5-6h), domperidone (T1/2 7-9h), alizapride (T1/2 3h)) within the last 12 hours.
- Patient taking clonidine (last dose within the last 24 hours).
- Use of topical ocular drugs modifying pupillary parameters in the last 24 hours.
- Bilateral eye surgery modifying the possibilities of variation in pupillary diameter bilaterally.
- Parkinson's or Alzheimer's disease at a dysautonomic stage.
- Admission to the emergency room for acute ocular pathology.
- History of diabetes at a dysautonomic stage.
- History of alcoholism at a dysautonomic stage.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: 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
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. |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Time Frame |
---|---|
The primary outcome will be the correlation between the pupillometry values and those obtained by the numerical pain rating scale with a correlation coefficient of 0.78.
Time Frame: 1 minute

1 minute

Secondary Outcome Measures
Outcome Measure |
Time Frame |
---|---|
The evolution of the Pupillary Unrest in Ambient Light depending on the type of opioid (morphine versus weak opioid like tramadol) received by the patient.
Time Frame: one hour

The endpoint will be the evaluation of the performance of pupillometry to predict the occurrence of Numerical Rating Scale (NRS) ≥ 4 using the ROC curve (AUC).
Time Frame: 1 minute
|
1 minute
|
The correlation of the pupillometric parameters with the level of anxiety quantified by a numeric scale next to 1 (not anxious) to 10 (maximum level of anxiety).
Time Frame: 1 minute

1 minute
|
The correlation between the initial measurement of PUAL and the analgesic response to an opioid medication.
Time Frame: one hour

The correlation between the pain measurements obtained by the reception nurse and that obtained by the patient.
Time Frame: 2 minutes
|
