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. Al 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.
