摘要
目的:对烧伤病区病原菌分布的特征进行研究。方法:对不同种类病原菌在烧伤病原菌中构成比及不同种类烧伤感染病原菌在全院同类病原菌中构成比的变化进行分析。结果:8年间从烧伤病区临床标本中共分离病原菌3 124株,其中包括金葡菌、MRSA 和肠球菌在内的革兰阳性菌构成比有升高的趋势,2002年超过了50%,但除阴沟肠杆菌和肺炎克雷伯菌外的多数革兰阴性菌的构成比有较明显地下降趋势。另一方面,烧伤感染病原菌中革兰阳性菌在全院同类病原菌中的构成比有逐年升高的趋势,金葡菌和 MRSA 的构成比均明显高于平均构成比;除阴沟肠杆菌和变形杆菌属外,其它革兰阴性菌的构成比均低于烧伤病原菌在全院病原菌中平均构成比。结论:目前本院烧伤病区病原菌中革兰阳性菌占多数,而且还有进一步增多的趋势;医院内革兰阳性菌的分布有向烧伤病区集中的趋势,针对烧伤感染病原菌这种分布特征适当调整烧伤临床感染的防治策略,有可能取得更好的疗效。
To investigate the yearly changes in pathogenic bacteria in a burn unit.Methods:The ratio of different pathogens isolated from burn wounds was surveyed in a burn unit to compare with that from the whole hospital.Results:More than three thousands of isolates were obtained from wounds of a burn unit in a 8-year peri- od.The ratios of Gram positive bacteria,including S.aureus,MRSA and Enterococcus were gradually increased, exceeding 50% of all isolates in 2002,whereas the ratios of the majority of Gram negative bacteria were decreased except Enterobacter cloacae and Klebsiella pneumoniae.On the other hand,the ratio of Gram positive bacteria ob- tained from the burn unit to that from the whole hospital were also on the increase year by year,especially S.au- reus and MRSA.However,the ratios of Gram negative bacteria in other wards were lower than that found in the burn unit.Conclusions:The results suggested that Gram positive bacteria were the predominant pathogens in our burn unit,and it might be increased in the future.It seems that in our hospital Gram positive bacteria flourished mainly in the burn unit.Considering this situation,it is important to adjust the strategy of burn infection control and treatment,especially in the burn unit.
