Objective measures of perceived pain may aid clinicians in decision-making regarding analgesia. This study aimed to assess the effectiveness of an algesimeter to assess the pain response of children to minor injury when compared with self-report.
A commercially available skin conductance algesimeter was used to record pain in children presenting with a minor injury to a district general hospital. The recordings were compared with self-reported pain scores using the Wong-Baker FACES® Pain Rating Scale.
Sixty-seven children below 16 years of age (36 females, 53.7%, mean age 11.9 years, standard deviation 3.1 years) were assessed. There was a significant correlation between self-reported pain and number of fluctuations in skin conductance per second for girls (r = 0.325, p = 0.027), but not for boys (r = 0.160, p = 0.194). There was no significant association between self-reported pain and number of fluctuation in skin conductance per second and patient age.
There was a significant correlation between self-reported pain and the number of fluctuations in skin conductance in girls, but not boys. There may be a number of reasons for this gender variation, including difficulty in rating pain and lack of sensitivity in the pain rating scale.
