Summary

New pain assessment parameter, called the Variation Coefficient of Pupillary Diameter (VCPD) described. This parameter allows evaluating the pain of patients during uterine contractions in obstetrical labor, and postoperatively in recovery room. This parameter also allows evaluating the level of pain in Intensive Care Unit (ICU), in intubated or tracheotomized patients moderately sedated (Riker score 3 or 4).

Detailed description

This study propose to recalculate the Variation Coefficient of Pupillary Diameter (VCPD) from pupil recordings performed in the Intensive Care Unit (ICU) in 2015-2016 and kept in the patients' records. From there, the Variation Coefficient of Pupillary Diameter (VCPD) will compare to the Behavioral Pain Scale (BPS), considered the gold standard pain assessment

The pupillary parameters were recorded with the AlgiScan® pupillometer (iDMed, Marseille, France), which allows the recording of Pupillary Diameter (PD) variations at the patient's bed at a sampling frequency of 67 hertz.
