In this study, we performed exit-site care using one of three methods (A: cleanse the exit site with povidone-iodine daily and apply gauze dressing; B: cleanse the exit site with povidone-iodine once a week, cover the site with a small gauze, and seal it completely with dressing film; C: the same as in B, above, except once every two weeks). The results show that there was a higher rate of positive bacterial growth in method A (17/24, 71%), and we concluded that the sterility of the exit site was not maintained 24 hours after cleansing. In methods B and C, in which the exit site was kept sealed, we did not detect bacterial growth in almost any of the cases (B = 0/44, C = 1/7). Although the patients took a bath and did not perform any care of the exit site for one to two weeks, the results show that the exit site was protected from bacterial invasion. We believe that this method could reduce exit-site infection while requiring no daily care.
在本研究中，我们采用三种方法之一进行出口部位护理（方法A：每天用聚维酮碘清洁出口部位并应用纱布敷料；方法B：每周用聚维酮碘清洁出口部位一次，用小块纱布覆盖该部位，并用贴膜完全密封；方法C：与上述方法B相同，但每两周进行一次）。结果显示，方法A的细菌生长阳性率较高（17/24，71%），我们得出结论，清洁后24小时出口部位的无菌状态未得到维持。在出口部位保持密封的方法B和C中，几乎在所有病例中均未检测到细菌生长（方法B = 0/44，方法C = 1/7）。尽管患者洗澡且一至两周未对出口部位进行任何护理，但结果显示出口部位受到保护未受细菌侵袭。我们认为这种方法可减少出口部位感染，同时无需每日护理。
