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.

糖尿病足负压引流:(Vacuum Assisted Closure, VAC)负压辅助创面愈合治疗技术是利用生物半透膜使开放创面封闭,使用专用负压机产生一定的负压,通过引流管和敷料作用于清创后的创面,是一种促进急慢性创面愈合的治疗方法。
下肢血管介入手术:糖尿病患者常伴有周围血管病变,尤其下肢动脉血管病变较为突出,是导致糖尿病足溃疡难以愈合的重要因素。
