牛羊膜在烧伤创面的临床应用研究

CLINICAL STUDY ON APPLICATION OF BOVINE AMNION ON BURN WOUNDS

目的 观察牛羊膜应用于烧伤创面的临床效果，并筛选最佳制备和储存方法。方法 2004年1月～2005年11月，随机选取58例浅Ⅰ度、深Ⅱ度、Ⅲ度切削痂植皮创面、供皮区及残余创面的患者，采用同体对照，将每例患者相同性质的创面等分为3分，分别贴附经0．1％洗必泰处理（A）、0．4％戊二醛处理（B）的牛羊膜和作为对照的凡士林油纱敷料（C），比较各组的临床效果，并对制备和储存牛羊膜的方法作出评价。结果 材料A较材料B质地柔软，随意性好，应用不需预处理。临床应用见：A、B组材料换药时患者疼痛轻微，C组较明显；A、B组创面愈合时间在各类创面中均低于C组，差异有统计学意义（P〈0．01），A、B组间比较，差异无统计学意义（P〉0．05）。A、B组创面感染率在深Ⅰ度和残余创面明显低于C组，差异有统计学意义（P〈0．05）；在浅Ⅰ度、Ⅲ度切削痂植皮创面和供皮区创面与C组比较，差异无统计学意义（P〉0．05），A、B组间比较，差异无统计学意义（P〉0．05）。结论 牛羊膜可以促进烧伤创面愈合，降低创面感染率，应用于常见的烧伤创面，戊二醛处理和洗必泰处理的牛羊膜疗效相似，但后者更易推广。

Objective To observe clinical effects of burn wounds treatment with bovine amnion and to screen the best method of preparing and storing of bovine amnion. Methods From January 2004 to January 2005,We selected randomly 58 patients with superficial Ⅱ° wound, deep Ⅱ° wound, autografting area for removal of eschars and tangential excision, fetching skin area or residual burn wound . Using auto-control, every burn wound was divided into 3 parts and was treated with 3 dressings： bovine amnion dealt with by 0. 1% chlorhexidine（group A）, bovine amnion dealt with by 0.4% glutaraldehyde（group B） and vaseline gauze dressing（group C as control）. The clinical effects were compared between different groups and the method of preparing and storing bovine amnion was evaluated. Results The dressing texture of group A was softer than that of group B, and its flexibility was fine. The pre-treatment was not necessary for dressing in group A. When the dressing was used on burn wounds in groups A and B, pain was slight, but pain was obvious in group C ; healing time in groups A and B was much less than that in group C, showing statistically significant difference （P〈0.01）. There was no statistically significant difference in healing time between groups A and B （P〉0.05）. The infection ratio of burn wound in deep Ⅱ° wound and residual burn wound of groups A and B is much lower than that of group C, showing statistically significant difference （P〈0.05）; in the other burn wounds there was no significant difference （P〉0.05）. There was no statistically significant difference between groups A and B （P〉 0.05）. Conclusion Bovine amnion could make benefit on burn wounds healing, reduce infection ratio of burn wounds, could be used on different kinds of burn wounds. The clinical effect between bovine amnion dealt with by glutaraldehyde and by chlorhexidine is similar. Whereas the latter is more easy to be popularized.
