随机选取反复使用的布朗氏牵引架 10个 ,分别固定选取牵引架的接触患肢与不接触患肢的 2块边长1cm的正方形表面 (A、B面 ) ,用无菌生理盐水棉球涂擦 2遍 ,并将棉球行普通细菌培养。对所培养出的细菌计数并分类。将上述牵引架表面包裹的绷带去除 ,用 0 5 %的“84”消毒液擦拭表面 3遍 ,更换绷带 ,用紫外线照射 1h ,再同法取菌和细菌培养。比较经消毒后 ,牵引架相同部位细菌培养的检出量和细菌种类的变化。结果示 :未经抑菌处理的牵引架A、B面细菌培养液中细菌量之间及经抑菌处理后A、B面细菌培养液中细菌量无差异 (P >0 0 5 ) ;但经抑菌处理前后 ,两组数据之间存在明显差异 (P <0 0 5 )。细菌种类无差异。
Random selection of Brown’s traction frame 10, respectively, were selected traction frame traction contact with the limbs and non-contact with the limbs 2 square 1cm side surface (A, B), with sterile saline tampon Rub 2 times, and the cotton ball ordinary bacterial culture. Bacteria cultured were counted and classified. Remove the bandage wrapped on the surface of the traction frame, wipe the surface with 0 5% “84” disinfectant for 3 times, replace the bandage, and irradiate with UV light for 1 hour, then take the bacteria and bacterial culture in the same way. After disinfection, the amount of bacterial culture in the same part of the traction frame and the change of bacterial species were compared. The results showed that there was no difference (P> 0.05) in the bacterial counts in the bacterial culture solutions of A and B after the bacteriostatic treatment without any antibacterial treatment. Before and after the antibacterial treatment, there was a significant difference between the two groups of data (P <0 05). No difference in bacterial species.
