NCT02576132

Brief Summary

This study was part of a quality improvement project at the Department of Anesthesiology and Intensive Care Medicine, Charité - Universitaetsmedizin Berlin. Being in pain is reported to be one of the most important stressors in critically ill patients and worsens outcome. The evaluation of pain using validated scores in patients who are able to self-report significantly improves the quality of analgesic therapy and health related outcomes in intensive care patients. However, behavioral pain score that are used in sedated or delirious patients, often underestimate the severity of pain. The primary aim of this study is to investigate if measurement of the pupillary light reflex Amplitude correlates with the results of pain assessment using validated pain scores in critically ill patients.

Outcome Measures

Primary Outcomes (1)

  • Correlation coefficient of pupillary light reflex amplitude and pain score

    Pain is measured by Numeric Rating Scale - Visualised or Behavioural Pain Scale or Behavioral Pain Scale - Non Intubated and pupillary light reflex amplitude is measured by pupillometry

    Participants will be followed up to 6 days during their intensive care unit stay

Secondary Outcomes (15)

  • Minimal pupil size [mm]

    Participants will be followed up to 6 days during their intensive care unit stay

  • Maximal pupil size [mm]

    Participants will be followed up to 6 days during their intensive care unit stay

  • Contraction speed of pupil [mm/s]

    Participants will be followed up to 6 days during their intensive care unit stay

  • Latency of pupil [ms]

    Participants will be followed up to 6 days during their intensive care unit stay

  • Pupillary light reflex [%]

    Participants will be followed up to 6 days during their intensive care unit stay

  • +10 more secondary outcomes
