Many factors may affect the efficiency of handwashing techniques. This study examined two interdependent factors: the time taken to wash the hands and the type of antiseptic solution used. A 3-minute initial scrub and 30-second consecutive scrub regimen was compared with a current standard regimen of a 5-minute initial scrub and a 3-minute consecutive scrub. Chlorhexidine gluconate 4% and povidone-iodine 7.5% were the antiseptics used in the two regimens. The sample (n = 34) was drawn from nurses employed in the operating room suite of a 950-bed hospital. Chlorhexidine gluconate was found to be responsible for lower numbers of colony-forming units of bacteria than povidone-iodine. The duration of the scrub had no significant effect on the numbers of bacteria when povidone-iodine was used. The optimal regimen was found to be the 5-minute initial and 3-minute consecutive scrubs with chlorhexidine gluconate.
许多因素可能会影响洗手技术的效率。本研究考察了两个相互依存的因素：洗手所需时间和所用抗菌溶液的类型。将3分钟的初次刷洗和30秒的连续刷洗方案与当前标准方案（5分钟初次刷洗和3分钟连续刷洗）进行了比较。两种方案中使用的抗菌剂分别为4%葡萄糖酸氯己定和7.5%聚维酮碘。样本（n = 34）取自一家拥有950张床位医院的手术室护士。结果发现，与聚维酮碘相比，葡萄糖酸氯己定能使细菌菌落形成单位数量更低。使用聚维酮碘时，刷洗持续时间对细菌数量没有显著影响。最佳方案是采用5分钟初次刷洗和3分钟连续刷洗，并使用葡萄糖酸氯己定。
