Objective: To review the application and research progress of transcutaneous oxygen pressure (TcPO 2) in scar assessment.
Methods: The original articles about scar and TcPO 2 were reviewed and analyzed.
Results: Hypoxia environment plays an important role in the progression of scar tissue. TcPO 2 can accurately reflect the oxygen tension of scar tissue, which is of great significance in the assessment of scar maturity, the guidance of scar treatment, and the study of correlations between hypoxia and the progression of scar.
Conclusion: TcPO 2 measurement is important in the study of scar evaluation, treatment, and correlation between hypoxia and scar formation.
目的: 总结经皮氧分压（transcutaneous oxygen pressure，TcPO 2）测量在瘢痕评估中的应用以及研究进展。.
方法: 查阅国内外与瘢痕以及 TcPO 2 相关的文献，并进行总结分析。.
结果: 组织中缺氧环境在瘢痕发生发展过程起重要作用，TcPO 2 能准确反映瘢痕组织内的氧分压情况，已用于瘢痕成熟度评估、指导瘢痕治疗以及研究缺氧对瘢痕发生发展的影响方面。.
结论: TcPO 2 测量在瘢痕评估、治疗以及缺氧与瘢痕发生机制研究中有重要意义。.
