    Objective: This study aimed to monitor skin temperature in pressure-prone areas of post-surgical patients in the intensive care unit using an infrared thermal camera and to examine the factors influencing the development of pressure injuries. Methods: This prospective descriptive study was conducted on patients admitted to the intensive care unit following surgery lasting more than two hours. Skin temperature differences between the sacrum, right and left gluteal regions, and right and left heels, compared to reference regions, were measured using an infrared thermal camera. Measurements were taken immediately upon admission to the intensive care unit. The correlation between patients' clinical conditions and observed temperature differences was analyzed. Results: The study included 59 patients and involved 590 thermographic evaluations. Temperature differences were identified between the reference areas and the right heel (-3.61 degrees C), left heel (-3.34 degrees C), left gluteal region (-2.9 degrees C), right gluteal region (-2.89 degrees C), and sacrum (-2.47 degrees C). A statistically significant correlation (p < 0.05) was found between patient age, albumin and hemoglobin levels, and temperature differences. Conclusions: Temperature differences between the high-risk body parts of patients at risk of pressure injury after long-term surgery were measured using an infrared thermal camera. It is observed that, hypoalbuminemia, and low hemoglobin levels affect the temperature difference in the sacrum, gluteal region, and heels in a statistically significant way especially in advanced age. The infrared thermal camera proved to be more effective than the Braden Risk Assessment Scale in assessing skin for pressure injury risk. Further studies with larger sample sizes are recommended to confirm these findings.
