BACKGROUND AND OBJECTIVE
To validate a standardized optimal national procedure for donor arm disinfection.
MATERIALS AND METHODS
A direct swabbing and plating technique was used to enumerate bacteria present on the arm pre- and postdisinfection. Twelve donor arm disinfection techniques were evaluated.
RESULTS
The Medi-Flex Adapted method, consisting of a two-stage process with an initial application of isopropyl alcohol followed by tincture of iodine, produced the best arm disinfection. A percentage reduction in bacterial counts of 99.79% (logarithmic reduction of 2.67) was obtained. Postdisinfection, 70% of donors had bacterial counts of zero, and 98% had counts of 10 or less.
CONCLUSION
The Medi-Flex disinfection method offers the English National Blood Service a validated, optimal 'best practice' disinfection technique and should contribute significantly to the reduction in risk of transmission of bacteria by transfusion.
背景与目的
验证一种标准化的全国最佳供体手臂消毒程序。
材料与方法
采用直接擦拭和接种技术对消毒前后手臂上存在的细菌进行计数。对12种供体手臂消毒技术进行了评估。
结果
改良的Medi-Flex方法包括两个阶段，首先使用异丙醇，然后使用碘酊，该方法能实现最佳的手臂消毒效果。细菌数量减少了99.79%（对数减少2.67）。消毒后，70%的供体细菌计数为零，98%的供体细菌计数为10或更少。
结论
Medi-Flex消毒方法为英国国家血液服务机构提供了一种经过验证的最佳“最佳实践”消毒技术，应能显著降低输血传播细菌的风险。
