摘要
我们探讨了47例病人伤后一周内的痂下组织菌量与伤后时间、年龄、面积和菌种的关系。结果表明:①伤后一周内痂下组织菌量与时间呈非常显著的正相关(r=0.9839,P【0.001);③婴幼儿和大于45岁的病人痂下组织菌量超过10~5/克组织发生例次,显著高于中青年组的患者(P【0.01);③大于30%面积组与小于30%面积组痂下组织菌量差异显著(P【0.05);④绿脓杆菌是侵袭至痂下组织的主要菌种之一,尤以大面积者多见。
The relationship between the number of bacteria in the subeschar tissue and time,age, burn extent in 47 patients within a week after burn injury are presented.The results showed ①There is a significant positive correlation between the number of bacteria in the subeschar tissue and time intervals following burn within the first week (r=0.9839,P<0.01);②In children (be low 4 years) and patients over 45 years,there is a higher incidence of having bacterial counts of over 10~5/gm of tissue than that of young and adolesent patients (P<0.01); ③There is a significant difference in subeschar bacterial count between major burns (>30% TBSA) and smaller burns (<30% TBSA P<0.05);④Pseudomonas aeruginosa is one of the most frequent bacteria isolated,especially in major burns.
