概括
与中性载体相比,氨酸 (HA) 带显示出慢性伤口愈合的潜力,可能改善关闭和减少疼痛. 然而,对于压力或糖尿病足等特定类型的证据仍然不足,需要进一步进行高质量的研究.
科学领域:
- 生物材料科学 生物材料科学
- 伤口治愈研究研究 伤口治愈研究
- 临床试验方法论 临床试验方法论
背景情况:
- 氨酸 (HA) 是一种天然存在的甘氨酸,在血膜中合成,在细胞外组织中发现.
- HA在慢性伤口愈合中的作用包括保持有利于细胞迁移的潮湿环境.
研究的目的:
- 系统地评估氨酸 (HA) 和其衍生物在促进慢性伤口愈合方面的疗效.
- 综合来自随机对照试验 (RCT) 的证据,将基于HA的治疗方法与其他伤口护理方式进行比较.
主要方法:
- 使用了广泛的Cochrane搜索方法,最新的搜索是在2022年2月进行的.
- 包括RCT,将HA或局部剂与其他用于压力,静脉,动脉,混合病因和糖尿病足进行比较.
- 使用GRADE方法评估证据确定性,从12项试验 (13篇文章) 的数据进行了定性合成,并从四项试验进行了定量分析.
主要成果:
- 关于HA对压力和糖尿病足的疗效的证据是不确定的,因为在比较中证据的确定性非常低.
- 对于腿部,HA可能会改善的完整愈合 (中度确定性证据),并且与中性载体相比,可以减少疼痛并增加大小的减少.
- 与其他料 (例如,合物,石膏,右素) 的比较产生了不确定的结果,通常受到证据确定性非常低,不精确或偏差风险的限制.
结论:
- 目前的证据不足以确定酸 (HA) 敷料对压力或糖尿病足的有效性.
- 与中性载体相比,HA在改善完全愈和潜在地减少疼痛和增加大小减少方面显示出可能的好处.
- 未来的研究应该专注于更大的样本大小和强大的遮方法,以提高慢性伤口管理中HA的证据质量和确定性.

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...

Glycosaminoglycans
4.9K
Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.

Clinical 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...

Inflammatory Response II: Inflammatory Exudate and Tissue Repair
5.1K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Local Anesthetics: Common Agents and Their Applications
481
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Hand hygiene
3.4K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.
