烧伤创面的细菌计数(综述)

BACTERIA COUNT IN BURN WOUNDS

本文就测量烧伤创面的细菌计数作一综述,介绍了各种测定细菌数量的方法:一、湿性拭子法;二、直接接触法;三、纱布法;四、活检组织法;五、吸纸片法。并指出为了使烧伤创面细菌计数更为准确以及解决有关问题成为国内外学者广泛重视的主要问题。因此,准确地反映烧伤创面组织中的细菌含量、操作简单、无创,重复性强是目前烧伤创面细菌定量计数发展的主要趋势。

Infections are life-threatening for burn pa-tients The severity of the infection and microorganism invasion depend upon the resist-ance of the host, the toxicity and the amount of the microorganism. This paper presents a review on the methods for determination of the count of bacteria in burn wounds. A historical review including different meth-ods for bacteria counting is presented. 1, Wet swab method, .2, direct contact method, 3, gauze method, 4, biopsy method which in-cludes tissue culture and tissue smearing and 5, paper sheet method. Uses of bacteria counting: 1, Predicting the viability of the grafts on the wound, /'. guiding the proper management of the wound and 3 mom toring and diagnosing pyemia. Wet swab method, direct contact method and gauze method are useful only for determination of the count of bacteria around the wound surface. The count often fluctuates under the mflu-nce of external factors and therefore the results are often unable to reflect proportionally the degree of infection in the deep tissue. The application of these methods have been limited lately Biopsy method is widely applied. But this technique is rather complicated and has low reproducibility.
