摘要：目的 對比觀察威伐光和短波紫外線在相同治療條件下局部照射感染性傷口的臨床療效。方法 選擇2015年1月～2017年6月清創術后或創傷后感染性傷口患者80例，隨機分為威伐光組和短波紫外線組，每組40 例。兩組均采用直接照射感染傷口創面，威伐光組治療時照射強度為380 mW/cm2，30 min/次，1次/d；短波紫外線組采用波長為254 nm，照射強度10 mW/cm2， 1次/d。于入組時和治療結束后，對比觀察傷口愈合情況、治療周期，采用視覺疼痛評分（VAS）分別對兩組患者進行疼痛評定。結果 兩組治療效果比較，威伐光組好于短波紫外線組，差異有統計學意義（P<0.05）。分組療效觀察結果：威發光治組在深部傷口患者療效好于短波紫外線組，同時威伐光組好轉和治愈天數較短波紫外線組明顯縮短，差異均有統計學意義（P<0.05）；在治療3 d、5 d、7 d后兩組患者的VAS評分均有下降，但威伐光組VAS下降明顯優于短波紫外線組，差異有統計學意義（P<0.05）。結論 威伐光和短波紫外線治療感染性傷口均有效，而威伐光的治療效果更加顯著，可以成為治療各種感染性傷口更好的方法。

Abstract：Objective To compare the clinical effects of Weifa light and short-wave ultraviolet radiation in the treatment of infectious wounds under the same treatment conditions.Methods From January 2015 to June 2017，80 patients with debridement wound or post-traumatic wound were randomly divided into Weifa light group and shortwave ultraviolet light group，40 cases in each group.The wounds were infected by direct irradiation in both groups.The irradiation intensity of Weifa light group was 380 mW/cm2 for 30 min/time and 1 time/d；The wavelength of UV light was 254 nm and the irradiation intensity was 10 mW/cm and 1 time/d.At the time of enrollment and after the treatment，the wound healing and the treatment cycle were compared.The visual acuity scores（VAS）were used to evaluate the pain in both groups.Results Comparison of the therapeutic effect of two groups，Weifa light group is better than the ultraviolet group，the difference was statistically significant（P<0.05）.The curative effect of the treatment group：The efficacy of the Weifa light group was better than that of the short-wave UV-ray in deep wound patients，at the same time Weifa light group cure days than UVB group decreased significantly，the differences were statistically significant（P<0.05）；in the treatment of 3 d，5 d，7 d after the two groups of patients with VAS score decreased，but Weifa light group VAS were lower than that of UVB group，the difference was statistically significant （P<0.05）.Conclusion Weifa light and short-wave UV treatments are effective for infectious wounds，and Weifa light treatment is more effective and can be a better way to treat a variety of infectious wounds.

感染性傷口一般多因開放性創傷或污染手術切口并發感染引起，具有發病率高、復發率高的特點，是導致機體死亡率增高的重要原因之一，以及隨之而來的抗生素的大量使用，是我國所面臨的重要公共衛生問題之一[1]。既往研究顯示，適當采用各種物理因子照射傷口，可以較好的促進傷口的愈合，降低傷口感染率。但是傳統的理療方法，如短波紫外線、激光等物理因子對感染性傷口效果一般[2-3]。隨著醫療技術的發展，威伐光作為一種新的光子治療已經開始在國外廣泛應用，其起效快、穿透力強、殺菌效果更好，比傳統的理療方式取得了更顯著地療效[4]，但國內目前尚未見文獻報道。因此，本文中我們觀察了威伐光對傷口愈合、療程和對疼痛的影響，初步探索了威伐光在治療感染性傷口中的作用，現將結果報告如下。……
