An interventional study of Video-pupillometer and Electrocardiogram in Anesthesia, General, sponsored by Centre Hospitalier Universitaire de Saint Etienne. Completed at 1 site in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2017-08-31.

Different pain assessment methods have been proposed to evaluate analgesic efficacy after surgical operation. Pain is a subjective phenomenon. Patient did his pain self assessment. But, cooperation of the patient is limited by cultural differences, language barriers or residual effect of products used while general anesthesia.
A lot of study were conducted to demonstrate and to quantify the pain after an operation. The aim will be dose analgesic treatment better without cooperation of the patient.
This sudy concerns patients on the post anesthesia care units one hour after their arrival. They will have electrocardiogram and video-pupillometer.
Primary objective is to compare Variation Coefficient of Pupillary Diameter (VCPD) obtained during a light flash and pain assessment realized thanks to Visual Analog Scale (VAS). Too, Variation Coefficient of Pupillary Diameter (VCPD) with electrocardiogram will be measured to demonstrate a correlation between the three parameters.
Exclusion criteria:
Patients have a surgical operation and have received analgesic treatment. One hour after the end of surgical patients will have electrocardiogram and video-pupillometer.
Other: Video-pupillometer · Other: Electrocardiogram
Video-pupillometer will be performed. In this study data will be collected and analyzed.
Also known as: Algiscan
Electrocardiogram will be performed. In this study data will be collected and analyzed.
Correlation between pupillary diameter (PD) and pain assessment
Correlation between pupillary diameter (PD) and pain in the post-operative period. PD will be measured by video-pupillometer. Pain will be measured by Visual Analog Scale (VAS).
Time frame: 1 hour post surgery
Correlation between pupillary diameter (PD) and heart rate
Correlation between pupillary diameter (PD) and heart rate in the post-operative period. Heart rate will be measured by electrocardiogram.
Time frame: 1 hour post surgery
