BackgroundPatients 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.ObjectivesTo evaluate the usefulness of skin conductance (SC) measurement in the assessment of analgosedation quality in infants requiring mechanical ventilation treated in N/PICUs.Material And MethodsThirty 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.ResultsWe 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.ConclusionsSkin 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.
