【摘要】 目的通过对术中清洗浸血纱布和器械的生理盐水细菌含量的动态观察与分析,了解术后切口感染与术中生理盐水含菌的关系。方法将层流手术室中,100例Ⅰ、Ⅱ类手术中浸血盐水,分别于手术开始(0min)至结束每隔30min采样计数盐水含菌量,并同期随访观察100例病人切口情况,对所得数据运用SPSS11.0统计软件进行统计学处理。结果Ⅰ、Ⅱ类手术盐水含菌量90min前各时间点对比,差异无统计学意义(P>0.05);90min与120min的盐水含菌量差异有统计学意义(P<0.05);同一时间点Ⅱ类手术浸血盐水含菌量高于Ⅰ类手术。Ⅰ类手术切口无感染,Ⅱ类手术切口感染组和未感染组比较,盐水含菌量差异有统计学意义,P<0.05,感染组盐水含菌量明显高于未感染组。结论Ⅰ、Ⅱ类手术开始后90min均应更换盐水和盛装盐水的容器;Ⅱ类手术中清洗浸血纱布和器械的生理盐水含菌量与术后切口感染有关。更多还原

【Abstract】 Objective To find out the relationship between the incision infection after operation and the bacterial content in physiological saline in operation by vital observation and analysis to the bacterial content in the physiological saline washing operating gauze dipped with blood and instruments. Methods In laminar flow operation room,collected the salt dipped with blood at 0min and every other 30min from operation beginning to end from 100 cases of I、Ⅱ types operation and counted the bacterial content, in the same time,observed their incision situation.The data was statistically treated with SPSS11.0 statistical software. Results The bacterial content in saline water of I、Ⅱ types operation at each timepoint before 90min had no statistical significance(P>0.05);The bacterial content in saline water between 90min and 120min had a statistical significance(P<0.05);at same timepoint, the bacterial content in saline water dipped with blood of II type operation was higher than that of I type operation.I type operation had no incision infection.The difference of the bacterial content in saline water between incision infection group and no incision infection group in II type operation(P<0.05).Conclusions The salt and its containers should be replaced after 90min in I、Ⅱ types operation;in Ⅱ type operation, the bacterial content of physiological saline washing operating gauze dipped with blood and instruments was related with incision infection after operation.更多还原
