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.

在《糖尿病足局部创面的抗菌治疗(2)》中,有位读者有些疑问:“我们的方法是在窦道的开口处及末梢处与横窦道方向垂直方向或者斜窦道方向有角度的切开,大约3-4CM,而一般不要沿着窦道完全切开。这方法有图解吗?”,对于这个问题,特别做一些回答,并借这个回答对糖尿病足切口的设计进行一些描述,供大家参考。
足趾有什么功能?可能很多人都没有注意到,而在糖尿病足的患者中,足趾出现问题的非常多,那么我们是否应该尽力保存患者的足趾?有什么方法保存患者的足趾?

为啥肛周脓肿这个常见疾病,大家都认为的小病,发展到急危重症,直至最后死亡?

临床,外伤性小腿伤口进入难愈合状态,也很常见!
