概括
在分裂厚度皮肤移植 (STSG) 之前,下肢伤口的深度除菌 (DD) 显著减少了移植失败,特别是在培养阳性病例中. 这种技术可以改善慢性伤口的STSG结果.
科学领域:
- 伤口愈合和组织再生
- 手术技巧 手术技巧
- 皮肤病学 皮肤病学
背景情况:
- 不愈合的下肢伤口往往需要分厚皮肤移植 (STSG) 进行关闭.
- 在STSG之前,对不可活性的组织进行有效的脱brid化至关重要.
- 对于STSG结果的最佳脱bridement深度仍然是一个研究领域.
研究的目的:
- 为了比较表面与深度脱bridement (DD) 对慢性下肢伤口中STSG结果的影响.
- 根据脱bridement深度来评估移植失败率.
- 分析伤口微生物学对不同脱bridement技术的有效性的影响.
主要方法:
- 在2014年12月至2022年12月期间接受STSG的慢性,非创伤性下肢伤口的回顾性审查.
- 脱bridement的分类为表面和深层 (到白组织层).
- 表面和深度除菌组之间的移植失败率的比较,对培养阳性和培养负性的伤口进行亚分析.
主要成果:
- 深度脱bridement (DD) 与显著较低的移植失败率 (10.5%) 相比表面脱bridement (22.2%).
- 多变量分析证实DD是减少移植失败的独立预测因子 (OR:0.0;CI,0.0-0.8).
- 在培养阳性伤口 (7.6%对22.1%) 中,DD的益处是显著的,但在培养阴性伤口 (13.6%对22.2%) 中没有.
结论:
- 深度除菌是一种优秀的技术,用于为STSG准备慢性下肢伤口.
- DD技术显示出更好的结果,特别是在需要STSG的慢性,培养阳性伤口中.
- 这一发现支持采用DD来优化STSG在特定伤口群体中的成功.

2.4K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:19Clinical Applications of Epidermal Stem Cells
2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:15Veins of Lower Limbs
706
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...
