文题释义:
壳聚糖护创敷料
:与细胞间质中黏多糖类基质的分子结构相近,细胞相容性好,为皮肤细胞的生长提供了有利环境,有利于创面愈合;其是自然界中惟一带正电荷的生物活性多糖,表面正电荷与血液红细胞表面负电荷相互作用,在创伤界面产生凝集黏附,快速封闭出血点;壳聚糖对人体组织具有高度亲和性,用于人体伤口、各种创面、溃疡不会发生任何排斥反应,且可促进胶原产生,促进创面愈合;壳聚糖独具优异生物相容性,对伤口周围的组织不产生刺激作用,尤其可以吸附伤口炎症部位酸性物质所释放出来的质子而起到镇痛作用;壳聚糖分子链上的正电荷和微生物细胞膜所带的负电荷相互作用,导致细菌的蛋白质和其他细胞成分泄漏,从而产生抗菌作用,对细菌、酵母、真菌等微生物,对一般表皮存在的葡萄球菌、大肠杆菌和热带白色念珠菌及烧伤患者易出现的绿脓杆菌、金黄色葡萄球菌和化脓性金黄色葡萄球菌感染等都有显著的抑制作用。


背景:以壳聚糖为原料制备而成的护创敷料,不仅具有天然抑菌、止血、促进伤口愈合的作用,而且具有良好的生物相容性、生物可降解性和生物学功能,被广泛应用于外科创伤、烧伤等治疗。
目的:评价试验产品——壳聚糖护创敷料用于深Ⅱ度烧伤创面的疗效和安全性,为试验产品的临床注册提供依据。
方法:将60例深Ⅱ度烧伤患者随机分为2组,试验组创面外敷壳聚糖护创敷料,对照组创面外敷壳聚糖生物医用敷料。以创面愈合时间、创面愈合百分率和疼痛评分为有效性指标,以不良事件和严重不良事件发生率和治疗前后实验室指标为安全性指标,评价试验产品的疗效和安全性。
结果与结论:①有效性指标:两组创面愈合时间比较差异无显著性意义[(21.23±6.84),(23.77±4.26) d,P > 0.05],两组治疗后14,21,28 d的创面愈合率比较差异无显著性意义;两组治疗后7,14,21,28 d的疼痛评分比较差异无显著性意义;②安全性指标:两组治疗前后的血常规、肝功能、肾功能各指标比较差异均无显著性意义;两组均未发生不良事件和严重不良事件;③结果表明,壳聚糖护创敷料治疗深Ⅱ度烧伤创面的疗效和安全性方面与对照产品相当。

Abstract:

BACKGROUND: Chitosan wound dressing has been extensively used in the treatment of wounds and burns, not only because of its bacteriastasis, hemostasis and promoting the wound healing, but also its good biocompatibility, biodegradability and biological functions.
OBJECTIVE: To evaluate the efficacy and safety of chitosan wound dressing for deep second-degree burn, thereby providing clinical basis for its registration.
METHODS: Sixty patients with deep second-degree burn were randomly allotted to two groups, and then subjected to the external application of chitosan wound dressing (experimental group) or chitosan biomedical dressing (control group), respectively. Then, the therapeutic efficacy was evaluated through healing time, recovering rate and pain scores, and the safety was evaluated through the incidence of adverse reactions and laboratory indexes before and after treatment.
RESULTS AND CONCLUSION: There were no significant differences in the wound healing time [(21.23±6.84) days vs. (23.77±4.26) days], recovery rate and pain scores between the experimental and control groups at 14, 21 and 28 days after treatment (P > 0.05). The blood routine, liver function and kidney function indexes before and after treatment did not differ significantly between groups. Additionally, neither adverse nor severe adverse events occurred in the two groups. These results indicate that the therapeutic efficacy and safety of the chitosan wound dressing are equivalent to the control product in the treatment of deep second-degree burn.
