Self Reports

This study aimed to examine the validity of the regional cerebral oxygenation using the near infrared spectroscopy technique for pain assessment in postoperative cardiac surgery adults in the intensive care unit. The near infrared spectroscopy for the assessment of pain has been studied in pediatric population, but its use in adult population especially in the critically ill is new. A total of 125 cardiac surgery intensive care unit patients from a Canadian university-affiliated hospital participated in this prospective repeated-measures study. Six assessments were completed at rest before, during, and 15 min after two procedures: (1) non-nociceptive (blood pressure measurement using cuff inflation) and (2) nociceptive (mediastinal tube removal). Regional cerebral oxygenation (%) was measured using the INVOS 5100 device (Somanetics, Troy, MI, USA). The Critical-Care Pain Observation Tool was employed to assess behavioral responses to pain. Self-reports of pain intensity and unpleasantness using 0–10 scales were also obtained. Participants were mostly males (89%) and averaged 65 of age. Regional cerebral oxygenation showed significant mild bilateral decreases (<1%; p<0.01) while higher mean Critical-Care Pain Observation Tool scores, pain intensity, and unpleasantness self-reports were obtained during mediastinal tube removal ( p < 0.001). Only the Critical-Care Pain Observation Tool score was mildly correlated to the right side regional cerebral oxygenation ( r −0.23; p < 0.01). Changes in regional cerebral oxygenation were mild and in the opposite direction. Unfortunately, the findings do not support the clinical use of the INVOS 5100 (Somanetics, Troy, MI, USA) and its regional cerebral oxygenation hemodynamic parameter for the assessment of pain in the cardiac surgery critically ill patients.

Near-infrared spectroscopy was first described in 1977 as a non-invasive technique to measure the cerebral oxygenation and cytochrome oxydase. Different techniques have been developed resulting in new instruments that make it possible to measure cerebral oxygenation in a non-invasive way. In this chapter the physiology and pathophysiology in relation to the measurement of cerebral oxygenation are explained and the direct possible clinical use enlightened, with special focus on measurement of ischemic cerebral hypoxia. The measurement of other organs like the liver, the bowel and the peripheral circulation are described. At the end, a short overview of future possible bed-side measurements like functional near-infrared spectroscopy, near-infrared imaging and photoacoustic measurements are given.
