摘　　要：目的观察碘仿在体内及体外的抑菌作用。方法①比较碘仿和四环素在体外对不同种类细菌的抑菌作用并绘制抑菌曲线;②建立48只肝外伤合并肝创面感染(分别用金黄色葡萄球菌、大肠杆菌和铜绿假单孢菌)大白兔模型,不同组肝创面分别填塞6%碘仿绷带、10%碘仿绷带、四环素软膏+普通纱布、生理盐水+普通纱布,术后1、3、7 d检验肝创面细菌并计数。结果体外抑菌实验证实碘仿组对大部分需氧菌的抑菌作用强于四环素组,对厌氧菌的抑菌作用与四环素类似;在大白兔体内,10%碘仿组对上述3种细菌抑菌作用显著优于四环素组(P<0.01)。结论碘仿对大部分细菌的抗菌作用强于四环素。Objective To investigate the bacteriostasis of iodoform in vivo and in vitro. Methods Bacteriostasis of iodoform and economycin against different species of bacteria was observed in vitro and the curves of bacteriostasis were obtained for each agent. In rabbit models traumatic liver injury complicated by infection of the wounds with Staphylococus aureus, Escherichia coli and Pseudomonas aerudomonas, common bandage supplemented respectively with 6% iodoform, 10% iodoform, economycin ointment, and saline were applied for wound addressing and the changes in the number of bacterium in the wounds was measured 1, 3, and 7 days later, respectively. Results Iodoform showed better bacteriostatic effect than economycin in inhibiting the growth of the majority of the aerobic bacteria in vitro, and its action on anaerobic bacteria appeared similar to the effect of economycin. In rabbit models, iodoform at the concentration of 10% showed significantly better bacteriostatic effect against the 3 species of bacteria than economycin (P<0.01). Conclusion Iodoform possesses more potent bacteriostatic effect than economycin against most bacteria.
