烧伤早期创面水疱液细菌菌种及定量的研究

目的 探讨烧伤早期创面水疱液中细菌菌种及含量的动态变化,确定伤后清除疱皮引流水疱液的最佳时机.方法 52例烧伤患者,于烧伤后第1～9天每日采集创面水疱液进行细菌定量计数,观察细菌含量的变化以及细菌的种类.结果 52例烧伤后第1～2天未检出细菌,细菌于第3天开始出现并逐渐增加,第6～7天达到并超过10^5 CFU/ml这一临界值.细菌种类以烧伤优势菌绿脓杆菌和金黄色葡萄球菌为主.结论 烧伤早期创面水疱液中细菌数量呈进行性增加的趋势,细菌种类以铜绿假单胞菌和金黄色葡萄球菌为主,伤后第6～7天为清除疱皮引流水疱液的最佳时机.

The observation of the quantity and kind of bacteria within the blisters in the earlier burn period

Objective To explore the developed changes of the bacteria count within the blisters in the earlier burn period and determine the best occasion of clearing the blisters and drain blister fluid. Methods 52 burn wound blisters were collected and bacteria count within the blisters was measured. The changes of bacteria cound within the blisters were observed. Results The bacteria were not discovered in the first 1 - 2 day. After then the bacteria count increased gradually. In the 6^th - 7^th day the bacteria count reached to 10^5CFU/ml. The kinds of bacteria were mainly pseudomonas aeruginosa and staphylococcus aureus. Conclusion During the earlier period postburn the bacteria count within the blisters grows up gradually. Bacteria are mainly pseudomonas aeruginosa and staphylococcus aureus. The 6^th - 7^th day postburn is the best occasion of clearing the blisters and drain blister liquid.
