Abstract

A reliably pain measure in newborns is difficulty and diagnosis and management are obstacles in neonatal units. This study aimed to determine whether the galvanic skin response, measured by innovative equipment, the SCMSTM, correlates with physiological and psychophysical scales for pain in neonates. Was also tested whether the skin conductance meets the theoretical assumptions of the Law of Initial Value and if it’s adequate to explain the responses to pain stimuli in relation to physiological and psychophysical indicators. The results indicate a high sensitivity of SCMSTM for detecting pain response with precision till 15†after the noxious stimulation, validated by other measures. The measures tested varied in their efficiency in sensitivity and consistency throughout the event. In this perspective the SCMSTM has great potential for psychophysical research and clinical use on pain in neonates due to meet several characteristics for accuracy and efficiency of the measure and low operating cost.
