Phases of Wound Repair

6.1K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

科学领域:

  • 血管医学 血管医学
  • 再生医学是一种再生医学.
  • 生物医学工程 生物医学工程

背景情况:

  • 针对伤口愈合的随机对照试验面临由于伤口异质性的统计挑战.
  • 超过4周的百分比面积减少 (PAR) 是FDA批准的中期终点,用于更强大的研究设计.
  • 研究新的治疗终点和研究设计对于推进伤口护理研究至关重要.

研究的目的:

  • 评估间歇性神经肌肉电刺激 (NMES) 的疗效,作为静脉腿 (VLU) 多层压缩的辅助.
  • 评估百分比面积减少 (PAR) 作为在受试者控制试验设计中的中间终点的实用性.
  • 为了比较VLU仅用压缩治疗的愈合率与压缩加NMES.

主要方法:

  • 一项受试者控制的研究比较了VLU患者4周的PAR.
  • 第一个阶段:多层压缩治疗4周.
  • 第二阶段:将NMES添加到多层压缩中,再持续4周;对照组仅接受了压缩.

主要成果:

  • 与单独压缩相比,接受NMES的患者显示VLU愈合率显著增加.
  • 仅接受压缩的对照组在愈合率上没有显著变化.
  • 间歇性NMES的普通腹部神经被证明是有效的加速VLU愈合.

结论:

  • 间歇性NMES是一种安全有效的辅助疗法,可加速静脉腿的愈合.
  • 百分比面积减少 (PAR) 是评估伤口愈合干预措施的一个有价值的指标.
  • 以 PAR 为终点的自我控制试验设计使得在较少的受试者和较短的试验持续时间下能够进行敏感的歧视.
