目的：探讨研究银离子敷料对热带地区患者慢性伤口愈合的作用。方法回顾性分析2013年1月-2015年1月琼海市人民医院收治的采用银离子敷料进行治疗的慢性伤口96例患者的临床资料。根据患者地区来源分为观察组（48例）和对照组（48例），其中观察组患者来自于海南本地，对照组患者来自于内地，比较两组患者慢性伤口的治疗效果。结果在治疗第10天与治疗第15天，观察组患者创口面积愈合率分别为（25.2±8.7）%与（37.9±9.1）%，显著性低于对照组的（37.9±9.2）%与（56.2±14.7）%（P〈0.05）。观察组患者0级、Ⅰ级、Ⅱ级、Ⅲ级的疼痛率与对照组比较，差异有统计学意义（P〈0.05），对照组显著性于观察组。观察组患者创口愈合时间、换药费用以及二次创伤积分分别为（29.2±5.4）d、（626.9±102.4）元以及（1.35±0.22）分，均显著高于对照组的（24.1±4.7）d、（412.3±90.8）元以及（1.04±0.19）分（P〈0.05）。结论使用银离子敷料后，内地患者相比于海南患者伤口愈合快，伤口疼痛感轻，二次创伤与感染的机会较少。

Objective To investigate clinical efficacy of silver ion dressing in treatment of chronic wounds in the trop-ics and mainland. Methods 96 patients with chronic wounds treated by silver ion dressing in People’s Hospital in Qionghai City from January 2013 to January 2015 were selected and randomly divided into observation group （48 cases） and control group （48 cases）. Patients in observation group were from Hainan, while patients in control group were from mainland. The therapeutic effect of the two groups were compared. Results After 10, 15 days of the treatment, the area of wound healing rates in observation group were （25.2±8.7）%and （37.9±9.1）%, which were significantly lower than the control group [ （37.9±9.2）% and （56.2±14.7）%] （P〈0.05）. The wound healing time of the observation group was （29.2±5.4） d, which was significantly longer than that of the control group [（24.1±4.7） d] （P〈 0.05）. The rates of grade 0,Ⅰ,II, Ⅲ of pain in observation group were significantly different from the control group （P〈0.05）, the control group was significantly better than the observation group. The treatment time, treatment costs and second-time trauma scores of the observation group were （29.2±5.4） d, （626.9±102.4） yuan and （1.35±0.22） respectively, which were significantly high-er than the control group [（24.1±4.7） d, （412.3±90.8） yuan, （1.04±0.19）] （P 〈 0.05）. Conclusion Using the silver ion dressing, the patients in mainland have lower wound healing time, lighter wound pain, less chance of second-time trau-ma scores than the Hainan patients.
