Objective Using the infrared thermal imaging system combined with the Braden pressure injury risk

assessment form to identify the potential risk of first-stage pressure injury in burn patients undergoing bed turning treatment，

and to clarify the role and advantages of infrared thermal imaging in preventing first-stage pressure injury in severe burn

patients. Methods A retrospective cohort study was conducted. A total of 34 patients with severe burn treated from January

2023 to December 2023 were collected， including 26 males and 8 females， aged 20 to 60 years old， all of whom were treated

by turning over bed regularly， and the patients were divided into Braden assessment group （Braden assessment form only，n=

17） and the combined assessment group （infrared thermography and Braden assessment form，n=17）.General clinical data

were collected at the time of admission. In addition， within 1 week after the patient was admitted to the hospital for 1 month，

the number of flipping times and the time of hip massage were adjusted every day according to the assessment of hip pressure

injury. The total number of flipping times and the total time of hip massage in 1 week were recorded in the two groups， and the

data were statistically analyzed. Results Compared with Braden assessment group， the combined assessment group had

significant statistical significance in reducing the number of flipping times and shortening the time of hip massage （P<0.05）.There was 1 case （1/17） of decubitus buttocks in both groups， and there was no statistical difference in the probability of pressure injury （P>0.05）.Conclusion Compared to using the Braden assessment form alone， the infrared thermal imaging combined with the Braden assessment form to monitor the compressed area of the buttocks in sever burn patients treated with flipping beds， can more accurately and timely detect the potential occurrence of stage 1 pressure injury； In addition， it can significantly reduce the number of flipping times and the time of hip massage， alleviate the workload of nursing staff， and has certain clinical application value.
