【 摘 要 】

The temperature distribution at the skin surface could be a useful tool to monitor changes in cardiac output. Goal: The aim of this study was to explore infrared thermography as a method to analyze temperature profiles of critically ill children. Methods: Patients admitted to the pediatric intensive care unit (PICU) were included in this study. An infrared sensor was used to take images in clinical conditions. The infrared core and limb temperatures (θ_c & θ_l) were extracted, as well as temperatures along a line drawn between these two regions. Results: The median [interquartile range] θ_c extracted from the images was 33.88°C [32.74-34.19] and the median θ_l was 30.21°C [28.89-33.13]. There was a good correlation between the θ_c and the clinical axillary temperature (rho = 0.39, p-value = 0.016). There was also a good correlation between the θ_c and θ_l (rho = 0.66, p-value = 1.2 e⁻⁰⁵). Conclusion: Thermography was found to be effective to estimate the body temperature. Correlation with specific clinical conditions needs further study.
