目的 評價(jià)甲殼素粉狀敷料對皮膚淺部切割傷的止痛作用及臨床應(yīng)用的安全性。方法 將60例淺部切割傷病人隨機(jī)分為兩組，敷用云南白藥組（對照組）30例，敷用甲殼素粉狀敷料組（實(shí)驗(yàn)組）30例，臨床觀察7 d并評價(jià)其臨床效果及安全性。結(jié)果 實(shí)驗(yàn)組止痛療效總有效率為96.66%，對照組100%，兩組比較無統(tǒng)計(jì)學(xué)意義（P＞0.05）；實(shí)驗(yàn)組疼痛起效時(shí)間有效率為80%，對照組96.66%（P＞0.05）；另外，兩組間紅腫消失率、滲液消失率、傷口愈合率、化膿性感染發(fā)生率比較無顯著差異（P＞0.05）。無不良事件發(fā)生。結(jié)論 甲殼素粉狀敷料具有良好的止痛效果，且臨床應(yīng)用安全。

Objective To investigate the analgesic effect of chitin mealiness excipient on skin superficial cut and its clinical application safety. Methods Sixty patients were divided into control group (treated with Yunnan Baiyao) (n=30) and treatment group (treated with chitin mealiness excipient) (n=30), then the clinical effect and safety were evaluated after 7 d observation. Results The total effective rates of analgesic efficacy in the treatment group and control group were 96.66% and 100%, respectively. There was no statistical significance between the two groups (P＞0.05); and the effective rates of initial time for analgesic function in the treatment and control groups were 80% and 96.66%, respectively (P＞0.05). In addition, the disappearance of swelling, effusion, healing, and the incidence of purulent infection between the two groups showed no significant difference (P＞0.05). No adverse reaction occurred. Conclusion Chitin mealiness excipient has better analgesic efficacy, and it is safe in clinical application.
