摘要SummaryEvidence from three randomized controlled trials failed to show a difference in infection rates for care of pin sites treated with povidone (polyvinylpyrrolidone) -iodine compared with pin sites treated with cleansing without an antibiotic regime.Two trials used the number of pin sites as the denominator for rates of infection,and slightly favored the use of povidone-iodine to reduce infections;one trial used numbers of patients to calculate the infection rate and showed the opposite outcome,with a higher incidence of infections in those patients treated with povidone-iodine.Additional randomized controlled trials may clarify these results.3项随机对照研究所获得的证据并不能明确,对于针道的护理,聚维酮碘清洗与不用抗生素单纯清洗比较,两处理组间感染率的发生是否在统计学上存在差异.其中2项临床研究以针道的数量进行统计,结果显示使用聚维酮碘消毒可能降低感染率,但是另1项临床研究则以患者数量进行计算,结果得出完全相反的结论,即使用聚维酮碘消毒可能增加感染率.因此,应进一步开展大样本随机对照研究,以明确相关结沦.
