摘要
目的比较普通型与轻量型补片在污染情况下对细菌的耐受能力。方法将32只大鼠随机分为二组,每组各16只。实验组植入轻量型补片,对照组植入普通型补片。取大肠埃希菌0.1 ml(浓度为5.5×103CFU/ml),喷洒在植入补片表面。分别于术后4 d及1周处死大鼠,取补片行细菌培养。结果 4 d时,实验组细菌培养阴性,对照组细菌阳性率100%,1周后,实验组细菌阳性率40%,对照组细菌阳性率100%,差异有统计学意义(χ2=16.1,P=0.01)。结论污染状态下,大孔轻量型网片较传统网片更能耐受细菌污染。
Objective To compare bacterial resistance of normal and lightweight patch in the pollution situation.Methods A total of 32 rats were randomized into two groups including 1 6 rats in each group.The experimental group was implanted with light-weight mesh and the control group with normal patch. The Escherichia coli was obtained with 0.1 ml （a concentration of 5.5×10^3 CFU/ml）,and sprayed on the surface of implantation.The rats were killed 4 days and 1 week after operation.The patch was applied with bacteria culture.Results In the experimental group,the bacterial culture after four days was negative and the amount of bacteria of control group are 1 00%.After one week,the bacteria beween the two groups had significant difference （χ2 =1 6.1 ,P=0.01 ）.Conclusion The macroporous light-weight mesh can tolerate more than the traditional ones for contamination.
