title: Physiological measures of assessing infant pain: a literature review.
abstract: Neonatal pain assessment is not standardized. Clinicians may use various parameters in the measurement of pain which can lead to different interpretations. Currently, there is no validated biological marker for assessing infant pain in any age group. However, in the non-verbal patient, the most feasible way to assess pain may be by evaluation of physiological parameters. The author conducted a systematic review of the literature using qualitative methods and seven research papers were selected for review, in which physiological measures were used in the assessment of neonatal pain. Heart rate was the most frequently used physiological pain measure in these studies. Oxygen saturation, blood pressure and respiratory rate lacked sensitivity and specificity and cannot be used independently. These measures may detect pain but cannot quantify it and are, therefore, not useful assessments of chronic pain. The multidimensional approach to pain assessment may be the most appropriate owing to the correlation between behavioural and physiological indicators of pain in the neonate.
