Skin temperature changes can be used to assess peripheral perfusion in circulatory shock patients. However, research has been limited to point measurements from acral parts of the body. Infrared thermography allows non-invasive evaluation of temperature distribution over a larger surface. Our study aimed to map thermographic patterns in the knee and upper thigh of 81 septic shock patients within 24 h of admission and determine the relationship between skin temperature patterns, mottling, and 28-day mortality. We extracted skin temperature measurements from zones corresponding to mottling scores and used a linear mixed model to analyze the distribution of skin temperature in patients with different mottling scores. Our results showed that the distribution of skin temperature in the anterior thigh and knee is physiologically heterogeneous and has no significant association with mottling or survival at 28 days. However, overall skin temperature of the anterior thigh and knee is significantly lower in non-survivors when modified by mottling score. No differences were found in skin temperature between the survivor and non-survivor groups. Our study shows the potential usefulness of infrared thermography in evaluating skin temperature patterns in resuscitated septic shock patients. Overall skin temperature of the anterior thigh and knee may be an important indicator of survival status when modified by mottling score.
皮肤温度变化可用于评估循环性休克患者的外周灌注情况。然而，相关研究一直局限于对身体末端部位的点测量。红外热成像技术能够对更大面积的体表温度分布进行无创评估。我们的研究旨在描绘81例感染性休克患者入院后24小时内膝关节和大腿上部的热成像模式，并确定皮肤温度模式、皮肤花斑与28天死亡率之间的关系。我们从与皮肤花斑评分相对应的区域提取皮肤温度测量值，并使用线性混合模型分析不同皮肤花斑评分患者的皮肤温度分布情况。我们的结果表明，大腿前部和膝关节的皮肤温度分布在生理上是不均匀的，且与皮肤花斑或28天生存率无显著关联。然而，根据皮肤花斑评分进行修正后，非存活者大腿前部和膝关节的总体皮肤温度显著较低。存活组和非存活组之间的皮肤温度未发现差异。我们的研究表明，红外热成像技术在评估复苏后的感染性休克患者皮肤温度模式方面具有潜在的应用价值。根据皮肤花斑评分进行修正后，大腿前部和膝关节的总体皮肤温度可能是生存状态的一个重要指标。
