Abstract

Objective

To evaluate the application of infrared thermography in assessing skin temperature characteristics of postoperative blanching erythema and Stage 1 pressure injuries in patients.

Methods

An observational study design was employed. We recruited 323 patients under general anesthesia who had an expected surgical duration exceeding 3 h and who experienced intraoperative sacral pressure. Infrared thermal images of the sacral region were captured, and skin assessments were conducted before entering the operating room, after admission to the post-anesthetic care unit, and daily for 3 days postoperatively.

Results

A total of 12 cases of Stage 1 pressure injuries and 81 cases of blanching erythema were identified. When the temperature in the affected area was elevated compared to the surrounding normal skin, Stage 1 pressure injuries demonstrated significantly higher ΔT values than blanching erythema (p = 0.001). When the temperature was reduced, the ΔT differences between Stage 1 pressure injuries and blanching erythema were not significant (p = 0.881). However, a higher proportion of Stage 1 pressure injury areas exhibited hypothermia (50 % vs. 8.6 %).

Conclusion

Postoperative blanching erythema and Stage 1 pressure injuries exhibit either warmer or cooler skin temperatures compared to adjacent normal skin. Compared to blanching erythema, Stage 1 pressure injuries are more likely to present with hypothermic areas or demonstrate more pronounced relative temperature increases in the affected regions.

红外热成像评价术后焯水性红斑和1期压伤的皮肤温度特征。

目的：探讨红外热像仪在评价术后焯水性红斑及1期压伤患者皮肤温度特征中的应用。方法：采用观察性研究设计。我们招募了323例全麻患者，预计手术时间超过3小时，术中出现骶骨压力。采集骶骨区域红外热像，并在进入手术室前、进入麻醉后护理单元后、术后3天每天进行皮肤评估。结果：1期压伤12例，烫红性红斑81例。与周围正常皮肤相比，当患处温度升高时，1期压力损伤的ΔT值明显高于焯水性红斑（p = 0.001）。温度降低后，1期压伤与烫漂性红斑的ΔT差异无统计学意义（p = 0.881）。然而，较高比例的1期压力损伤区域表现出低体温（50%对8.6%）。结论：与邻近正常皮肤相比，术后焯水性红斑和1期压伤的皮肤温度升高或降低。与焯水性红斑相比，第1阶段压伤更有可能出现低体温区域或在受影响区域表现出更明显的相对温度升高。

期刊介绍： The Journal of Tissue Viability is the official publication of the Tissue Viability Society and is a quarterly journal concerned with all aspects of the occurrence and treatment of wounds, ulcers and pressure sores including patient care, pain, nutrition, wound healing, research, prevention, mobility, social problems and management. The Journal particularly encourages papers covering skin and skin wounds but will consider articles that discuss injury in any tissue. Articles that stress the multi-professional nature of tissue viability are especially welcome. We seek to encourage new authors as well as well-established contributors to the field - one aim of the journal is to enable all participants in tissue viability to share information with colleagues.
