Abstract

The treatment of skin wounds is a key research domain owing to the important functional and aesthetic role of this tissue. When the skin is impaired, bacteria can soon infiltrate into underlying tissues which can lead to life-threatening infections. Consequently, effective treatments are necessary to deal with such pathological conditions. Recently, wound dressings loaded with antimicrobial agents have emerged as viable options to reduce wound bacterial colonization and infection, in order to improve the healing process. In this paper, we present an overview of the most prominent antibiotic-embedded wound dressings, as well as the limitations of their use. A promising, but still an underrated group of potential antibacterial agents that can be integrated into wound dressings are natural products, especially essential oils. Some of the most commonly used essential oils against multidrug-resistant microorganisms, such as tea tree, St. John's Wort, lavender and oregano, together with their incorporation into wound dressings are presented. In addition, another natural product that exhibits encouraging antibacterial activity is honey. We highlight recent results of several studies carried out by researchers from different regions of the world on wound dressings impregnated with honey, with a special emphasis on Manuka honey. Finally, we highlight recent advances in using nanoparticles as platforms to increase the effect of pharmaceutical formulations aimed at wound healing. Silver, gold, and zinc nanoparticles alone or functionalized with diverse antimicrobial compounds have been integrated into wound dressings and demonstrated therapeutic effects on wounds.

摘要

皮肤创伤的治疗是一个重要的研究领域,因为皮肤组织具有重要的功能和美学作用。当皮肤受损时,细菌很快会渗透到下面的组织中,这可能导致危及生命的感染。因此,有必要采取有效的治疗方法来处理这些病理状况。最近,负载抗菌剂的创伤敷料已成为减少伤口细菌定植和感染的可行选择,以改善愈合过程。本文综述了最突出的载抗生素创伤敷料,以及它们使用的局限性。天然产物,特别是精油,是一种有前途但仍被低估的潜在抗菌剂,可以整合到创伤敷料中。本文介绍了一些最常用于对抗多药耐药微生物的精油,如茶树油、圣约翰草、薰衣草和牛至油,以及它们在创伤敷料中的应用。此外,另一种具有令人鼓舞的抗菌活性的天然产物是蜂蜜。我们强调了来自世界不同地区的研究人员在载有蜂蜜的创伤敷料方面进行的几项研究的最新结果,特别强调了麦卢卡蜂蜜。最后,我们强调了最近在使用纳米颗粒作为平台来提高旨在治疗伤口的药物制剂的效果方面的进展。银、金和氧化锌纳米颗粒,单独或用各种抗菌化合物功能化,已被整合到创伤敷料中,并在伤口治疗方面显示出疗效。
