作者用雌性小白鼠作试验,对局部用抗生素,预防性系统应用抗生素及局部用聚乙烯吡咯酮碘(Povido-ne-iodine)在减少伤口感染上的效果进行比较评价。试验分三批进行,结果表明:(1)局部用抗生素,对照组全部发生伤口感染;单用生理盐水冲洗组,75％发生感染;头孢唑啉冲洗组,仅17.5％发生感染。提示头孢唑啉冲洗伤口,使感染明显地减少(P<0.001)。生理盐 The authors used female mice as a test to compare the efficacy of topical antibiotics, prophylactic systemic antibiotics, and topical Povido-ne-iodine in reducing wound infections. The test was conducted in three batches. The results showed that: (1) wound infection was observed in all the topical antibiotics and the control group. In the group treated with saline alone, 75% of the patients were infected. In the cefazolin irrigation group, only 17.5% of the patients were infected.
