In this study, the antimicrobial efficacy of hand washing (HW) and hand washing plus rubbing with an alcohol-based solution (HWR) on numbers of total and transient flora colonies on the hands of healthcare workers (HCWs) during routine patient care was assessed. Samples were collected, using a standard bag broth technique, from the hands of 154 HCWs, before and immediately after carrying out a hand hygiene procedure. The numbers of total and transient flora colonies per plate were counted and transient pathogens were identified. A significant statistical difference between ward speciality was detected with respect to the isolation rate of transient flora. Transient hand flora were recovered from 25.3% of HCWs before carrying out the hand hygiene procedure. With respect to the disappearance and prevention of regrowth of transient flora after hand hygiene, the HWR technique was significantly more effective than HW. In conclusion, a disinfectant should be added to the hand washing process to achieve optimum protection against nosocomial infections in routine hospital practice.
在本研究中，评估了常规患者护理期间洗手（HW）以及洗手后再用含酒精溶液揉搓（HWR）对医护人员（HCW）手部总菌落数和暂住菌菌落数的抗菌效果。采用标准袋肉汤技术，在154名医护人员进行手部卫生程序之前和之后立即从其手部采集样本。对每个培养皿中的总菌落数和暂住菌菌落数进行计数，并鉴定暂住病原体。在暂住菌的分离率方面，检测到病房专业之间存在显著统计学差异。在进行手部卫生程序之前，25.3%的医护人员手部检出暂住菌。就手部卫生后暂住菌的消失和再生长预防而言，HWR技术比HW显著更有效。总之，在医院常规实践中，应在洗手过程中添加消毒剂，以实现对医院感染的最佳防护。
