数字式多功能外伤清洗机应用的实验研究

Experimental study on the application of DMTR in rabbit trauma model debridement

目的:探讨数字式多功能外伤清洗机(Digital multifunction trauma rinser,DMTR)对开放性创伤的清洗效果。方法:选用2～3kg家兔建立浅Ⅱ°烫伤模型、切割伤模型、撕脱伤模型,用大肠杆菌污染创面,10min后分别用数字式多功能外伤清洗机和倒水法冲洗伤口,然后进行伤口大体观察,并取材涂片计数细菌。结果:数字式多功能外伤清洗机清除细菌的能力与倒水法比较有统计学意义。结论:数字式多功能外伤清洗机具有高效率清除细菌、组织碎屑的作用,效果优于倒水法,且使用方便,值得推广应用。

Objective：To investigate the effectiveness of digital muhifunction trauma rinser（DMTR） in open wound irrigation. Method：Rabbits weighing 2-3kg were recruited to mimic wounds including superficial second degree scald,concis and avulsed wound,then contamination with Bacillus coli was followed. Irrigating using DMTR or dumping washing method was performed in 10 minutes. After the evaluation of the cleanness of the wounds, bacteria counts in wound were performed through smear method. Result：The effectiveness difference between DMTR and dumping washing method was statistically significant. Conclusion：DMTR is superior to dumping washing method in wound irrigation. It obviously removes germs,fragments and foreign bodies in wound with higher effficiency.It is convenient and worthy applying.
