NCT05633069

Brief 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).

Outcome Measures

Primary Outcomes (1)

  • Correlation between fluctuations in Pupillary Diameter (PD), as assessed by the Variation Coefficient of Pupillary Diameter (VCPD) and the level of pain.

    Variation Coefficient of Pupillary Diameter (VCPD) calculate from continuous pupil recordings during tracheal aspirations, considered as a painful procedure. The nurse in charge of the patient scored the Riker sedation score before endotracheal suctioning and the pain level estimated by the Behavioral Pain Scale (BPS) scale before and during endotracheal suctioning.

Study Arms (1)

Patients requiring orotracheal intubation or tracheostomy

Patients hospitalized in the surgical Intensive Care Unit (ICU) of the University Hospital of Saint-Etienne between September 2015 and August 2016 for medical-surgical pathologies, requiring orotracheal intubation or tracheostomy, and presenting on the day of recording a Riker sedation score of 3 or 4 will be included. Datas analysed by medical records.

Other: Datas analysed by medical records

Interventions

Datas analysed by medical records : pupillary parameters: pupillary diameter and pupillary diameter variation. heart rate, the blood pressure, the Behavioral Pain Scale (BPS) pain score before and during painful procedures. 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.

Study Population

Patients hospitalized in the surgical Intensive Care Unit (ICU) of the University Hospital of Saint-Etienne between September 2015 and August 2016 for medical-surgical pathologies, requiring orotracheal intubation or tracheostomy, and presenting on the day of recording a Riker sedation score of 3 or 4 will be included.

You may qualify if:

  • hospitalized in the surgical Intensive Care Unit (ICU) of the University Hospital of Saint-Etienne between September 2015 and August 2016 for medical-surgical pathologies
  • requiring orotracheal intubation or tracheostomy
  • and presenting a Riker sedation score of 3 or 4.

You may not qualify if:

  • cerebral palsy
  • curarization
  • paraplegia or tetraplegia
  • intensive care neuromyopathy
  • ocular pathology
  • history of severe dysautonomic disease that could influence the evaluation of the Behavioral Pain Scale (BPS) or Variation Coefficient of Pupillary Diameter (VCPD) score
  • receiving antiarrhythmic treatment that could make the interpretation of the results difficult
  • on metoclopramide, droperidol, clonidine, or dexmedetomidine, which are known to alter the pupil dilation reflex.
