Assessment of Prolonged Pain in Infants With Excessive Crying: Contribution of Infrared Thermal Imaging - The NEOTHERM Pilot Study
Condition(s) studied
Study summary
NEOTHERM is a multicenter, prospective, observational pilot study examining whether infrared thermal imaging (ITI) can contribute to the assessment of prolonged pain in infants with excessive crying. Thermal measurements of the face and body will be compared with scores obtained using the EDIN behavioral pain and discomfort scale. The study will also examine associations between ITI measures, EDIN scores, and hair cortisol concentrations as a biomarker of prolonged stress, and will describe early motor organization and psychomotor development using General Movements Assessment and Bayley-4. Eighty infants will be enrolled in two comparison groups based on daily crying duration and assessed longitudinally at two standardized visits. The main hypothesis is that ITI will identify cutaneous thermal changes associated with prolonged pain and that these measures will be associated with EDIN scores.
Eligibility
Primary outcome measure(s)
- Association Between Infrared Thermal Imaging Indices and EDIN Total Score — At baseline (T1) and approximately 8 weeks after baseline (T2)
Mean skin temperatures will be extracted from predefined body and facial regions of interest. Infrared thermal imaging indices will include absolute bilateral body temperature differences, central-to-peripheral temperature gradients, and intra-facial temperature gradients calculated relative to the forehead. An absolute temperature difference greater than 0.5°C will be considered an abnormal thermal asymmetry. The EDIN is a behavioral scale assessing facial expression, body movements, sleep, interaction, and consolability. Each item is scored from 0 to 3. Higher scores indicate greater pain- or discomfort-related behaviors; a total score of 5 or higher indicates probable prolonged pain. Concordance between infrared thermal imaging indices and EDIN total scores will be quantified using Spearman rank correlation coefficients at each assessment. Thermal images will be analyzed by an external assessor blinded to the EDIN score and cohort classification.
