Abstract
Background: Adequate tissue oxygenation is a key determinant of diabetic foot ulcer (DFU) outcomes. Though transcutaneous oxygen pressure (TcPO2) is the gold standard for evaluating tissue oxygenation, its limited availability restricts routine clinical use. Consequently, toe pressure is frequently utilized as a practical surrogate; however, the direct correlation between these two modalities has yet to be rigorously investigated. This study aimed to assess the correlation and agreement between TcPO2and toe pressure in patients with DFUs.
Methods: A retrospective review was conducted on 837 DFU patients who received simultaneous TcPO2and toe pressure assessments.
The correlation between the two tests was analyzed using the Pearson correlation coefficient, and agreement was evaluated using Bland– Altman analysis. To aid interpretation, a scatterplot and Bland–Altman plot were generated.
Results: TcPO2and toe pressure demonstrated a strong correlation (R=0.66; 95% confidence interval, 0.62 to 0.70; P<0.001). Bland–
Altman analysis showed a mean bias of 26.9 mmHg (standard deviation of differences, 28.8 mmHg; 95% limits of agreement, −28.9 to 82.6 mmHg) between toe pressure and TcPO2, reflecting limited agreement and increased variability at higher perfusion levels.
Conclusion: TcPO2and toe pressure are strongly correlated. However, they are not interchangeable, particularly in DFU patients with high tissue perfusion.

一旦有伤口出现,往往会有疼痛的症状发生,这些疼痛反复发作,让许多患者困扰不已。实际上导致患者出现伤口疼痛有些是伤口愈合期间的正常症状,有些由于伤口感染等原因导致,我们应该区别对待,区别处理。
伤口的愈合除了需要良好的环境以外,必不可少的就是需要充足的营养物质的提供。今天小编就给大家介绍一下与伤口愈合紧密相关的一些营养素(分为两次课程)。

对于每一个人来说、食物中富含营养素的多少,及其自身吸收利用的程度的高低,将决定着他本人的营养状况。目前对一个人营养状况的评价,大体上是根据我国各类人群中每日膳食营养素供给量的标准米衡量的。对符合每日供给量标准的为营养状况良好,超过的为营养过剩,不足的为营养不良。受历史条件的限制,祖国医学认为人的营养状况取决于饮食结构与进食量是否合理,合理的饮食结构能保障营养素的供给,所以营养状态良好的饮食标准应该是下面几点。
