Abstract
Patients treated in neonatal/pediatric intensive care units (N/PICUs) are frequently exposed to pain. To assess its severity, several behavioral and behavioral-physiological scales are used, but their usefulness is limited. It is therefore justified to search for additional methods to assess the adequacy of analgesia and sedation in these patients. To evaluate the usefulness of skin conductance (SC) measurement in the assessment of analgosedation quality in infants requiring mechanical ventilation treated in N/PICUs. Thirty infants aged 6-208 days treated in 6 N/PICUs, mechanically ventilated and receiving analgosedation, were included for the study. Simultaneous COMFORT-B assessment and SC measurement using SCA (skin conductance algesimeter) monitor were performed. Due to technical problems, not all of the SC records could be interpreted, and finally 412 simultaneous assessments on the COMFORT-B scale and SC measurements in 29 patients were analyzed. We found a statistically significant correlation between the COMFORT-B scoring and the SC measurements. Additionally, SC was significantly lower when the behavioral score indicated deep sedation, in comparison to periods when it indicated moderate or insufficient analgosedation. Skin conductance measurements are comparable with the COMFORT-B rating in mechanically ventilated infants receiving analgosedation. The SCA monitor may be of value in the assessment of analgosedation quality, and in particular may identify the situation where sedation is deep. Further research is needed regarding the suitability of this device in clinical practice.
Highlights
As defined by the International Association for the Study of Pain, pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.[1]

Summary
As defined by the International Association for the Study of Pain, pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.[1]. It is understandable that patients treated in neonatal/pediatric intensive care units (N/PICUs) are exposed to pain. Newborns and infants may suffer both from illness, after surgery, and from chronic use of the procedures causing discomfort, such as tracheal intubation, as well as experience additional procedural pain. Our goal was to assess the usefulness of Skin Conductance Algesimeter (SCA; MedStorm Innovation, Oslo, Norway) in the assessment of pain in mechanically ventilated infants receiving analgosedation by comparing the measurements with the scoring on the behavioral (COMFORT-B) scale. It is justified to search for additional methods to assess the adequacy of analgesia and sedation in these patients
