文题释义:
凝胶敷料
:水凝胶是功能高分子材料的一种,内部带有强烈的亲水基团,因而对水有特殊吸附作用,通过分子间交联,形成网状结构。吸水性凝胶材料吸水的特点不同于海绵、棉布等吸附材料,它可吸收是自身质量成百上千倍的水,并与水牢固结合,然后膨胀形成水凝胶。与传统敷料相比,水凝胶能促进伤口愈合、减轻疼痛,改善创面微环境、抑制细菌生长。水凝胶特别适用于常见的体表创伤,如擦伤、划伤、压疮等各种皮肤损伤。
骨外露创面:骨外露创面是骨科临床工作中最常遇到的创面之一,并且临床工作中经常遇到局部软组织挫伤严重、清创术后皮瓣坏死的骨外露创面,其多因为骨外露周围软组织坏死感染而不能及时用健康肌肉覆盖骨折部,导致不能及时用皮瓣移植修复创口。以往采用的无菌换药法很难使创面愈合,且处理起来很棘手。轻则导致反复植皮失败,病人痛苦不堪,医疗费用增加;重则导致骨坏死、骨髓炎、肢体残疾,甚至截肢。


背景:骨外露创面是骨科临床常需要处理的问题,涉及到开放性骨折、骨肿瘤、骨髓炎等诸多疾病的治疗,其中尤其以开放性骨折所致的软组织缺损骨外露的处理最为困难。常规的清创换药或负压封闭引流技术很难使骨外露创面获得愈合,且过程繁琐,给患者造成痛苦。
目的:评价各种类型的敷料的优缺点,并从新型水凝胶敷料所具有的使创面环境保持水分湿润、恢复皮肤的物理屏障、有利于日常敷料更换等优点对其在骨外露创面中的在骨组织应用进行综述。   
方法:以英文检索词为“hydrogel dressing,bone exposure wound, traditional wound dressing,antibiotic”及中文检索词为“骨外露创面,水凝胶敷料,传统创面敷料,生长因子”,由第一作者检索2000至2016年PubMed数据库及中国知网中文科技数据库,查阅近年相关文献,最终保留53篇文献,从中对传统敷料与新型敷料在骨组织工程中的应用进行综述。
结果与结论:骨外露创面的治疗由于其涉及到开放性骨折、骨肿瘤、骨髓炎等诸多疾病的治疗,仍然是是骨科临床亟需处理的问题。目前,新型水凝胶敷料所具有的各项独特的优点,能够为骨外露创面的患者提供更加完善的治疗方案,解决了骨外露创面的再生修复,抗菌感染等相关的问题,另外,凝胶敷料所具有的稳定的药物缓释的特性,使得载药水凝胶敷料成为目前的研究热点之一。

Abstract:

BACKGROUND: Bone exposed wounds are frequently required to deal with in orthopaedic surgeries, involving the treatment of open fractures, bone tumors, osteomyelitis, and many other diseases, in which the defect of soft tissue caused by open fractures is the most difficult to deal with. Conventional debridement or negative pressure closed drainage technology is difficult to make bone exposed wounds heal, and the process is extremely cumbersome, during which, patients suffer a lot of pain.
OBJECTIVE: To evaluate the advantages and disadvantages of the various types of dressings, and review the application of new hydrogel dressing in bone exposed wounds based on its advantages, such as keeping wound environment moisture, restoring skin physical barrier, contributing to routine dressing change.
METHODS: A computer-based online retrieval of PubMed and CNKI databases was performed to search papers published between 2000 and 2016 using the key words “hydrogel dressing, bone exposed wound, traditional wound dressing, antibiotic” in English and Chinese, respectively. A total of 55 papers suitable for final analysis from the application of traditional and new dressings in bone tissue engineering were reviewed.
RESULTS AND CONCLUSION: The treatment of bone exposed wounds involves the treatment of many diseases, such as open fractures, bone tumors, osteomyelitis, which is still an orthopedic problem to solve. The novel hydrogel dressings with unique advantages are able to provide better plans for bone exposed wounds, and the use of these dressings solves the regeneration and repair of exposed bone, and improves the infection of antibiosis. In addition, the gel dressings currently have become a hot spot of research because of the characteristics of sustained-release.
