摘要:

背景:银离子敷料应用的理论基础是湿性愈合理论,利用创面的湿润环境减少组织坏死、加速新生上皮形成、减轻治疗过程中病患的疼痛、强化各种生长因子对伤口内组织细胞的修复,因此具有抗感染、促进创面肉芽形成、上皮增生的作用,有利于慢性创面的愈合。
目的:对比观察银离子敷料与常规消毒敷料在慢性创面治疗中的作用。
方法:选择解放军南京军区南京总医院汤山分院住院的慢性创面未愈合患者40例,采用随机数字表法分两组治疗,在预防及控制感染、改善组织循环等常规处理后,试验组给予银离子敷料换药处理,对照组采用常规消毒敷料换药。于治疗前及治疗后7,14,21 d进行创面分泌物细菌培养,观察创面愈合情况,以疼痛目测类比评分评估疼痛感。
结果与结论:与对照组比较,试验组创面细菌检出率明显降低(P < 0.05),创面愈合时间明显缩短(P < 0.05),换药时疼痛程度明显减轻(P< 0.05)。试验组治疗过程中的医疗费用与对照组相当(P > 0.05)。两组均未发生任何不良反应。结果表明银离子敷料在慢性创面治疗中的作用明确,可有效抗菌,促进创面肉芽、上皮增生,促进创面愈合,减轻病患治疗过程中的痛苦且无不良反应。

Abstract:

BACKGROUND: Silver ion dressing can reduce tissue necrosis, accelerate the epithelial formation, relieve the patient’s pain during the treatment, and strengthen various growth factors for wound repair, which is based on the theory of wet healing theory. It has obvious advantages for chronic wound healing, such as anti-infection and promoting wound granulation and epithelial hyperplasia.
OBJECTIVE: To observe the efficacy of silver ion dressing used in healing of chronic wound.
METHODS: A total of 40 patients who had chronic wounds were selected from Tangshan Branch Hospital of
Nanjing General Hospital of Nanjing Military Command. All cases were divided into two groups. The treatment group was treated with silver ion dressing, and the control group was treated with routine dressing. Secretions extracted from wound were used for bacterial culture prior to and 7, 14, and 21 days after treatment. Healing condition and velocity were observed and wound pain was assessed using visual analog scale.
RESULTS AND CONCLUSION: The detection rate of wound bacteria in the treatment group was significantly lower than that of the control group (P < 0.05). And the time of healing was shorter in the treatment group than the control group (P < 0.05). Wound pain during dressing change was relieved (P < 0.05). Medical costs showed no difference between the two groups (P > 0.05). No adverse reaction occurred in the two groups. These findings indicate that silver ion dressing used in chronic wound healing can prevent infection and promote wound granulation or epithelial hyperplasia. It can effectively promote wound healing and has no bad reaction.
