The germs on the hands of medical personnel in medical institutions have become the chief pathogens for hospital infection. These pathogens can be acquired not only from infected wounds or drainage wounds but also from normal and whole skin regions. Hand washing and disinfection is one of the most important measures for preventing hospital infection. The paper describes the definitions of hand washing, hygienic hand disinfection and surgical hand disinfection and discusses the action mechanisms, effects and features of various hand hygiene products currently in use, such as alcohol, hibitane glucose saline and hexachlorophenol. It enumerates a number of problems inhand hygiene, including low rate of hand hygiene observance on the part of medical personel, insufficient attention to hand hygiene on the part of medical institutions, reduction of germs' sensitivity to disinfectants, and the occurrence of contact dermatitis in disinfectant usage. The paper also gives an account of some of the latest strategies and countermeasures aiming at improving the status of hand hygiene, These include ways of lowering the incidence of contact dermatitis, reducing the bad effects of germicides, and raising the rate of hand hygiene observance.

Objective To raise risk exposure awareness for spreading pathogenic microorganisms in anesthesia procedures and normalize aseptic technique of anesthesiologists,thus minimizing postoperative infection.Methods Choose 45 cases of general anesthesia.Respectively before anesthesia induction (Time0),five minutes after induction (Time1) and two hours after anesthesia (Time2),make bacteriological tests on seven spots vulnerable to contamination,including the three-way stopcock,screwtype hose coupling,oxygen flux knob,pressure-release valve surface,exhaled breath entry of the anesthesia machine,oxygen intake of the breathing loop of the anesthesia machine,and operating desktop of the anesthesia cart.Results Contamination risk exposure of the stopcock extends with the operative time.At Time 0,it is sterile; at Time 1,84.4%of the 45 cases are found with bacteria growth,with colony count of 1~2CFU/ml; at Time2,colony counts at various monitoring points range 7~21 CFU/ml,of which the differences between Timel group and Time0,as well as Time2 and Time0 are statistically significant(P<0.05).Colony counts at other monitoring points comply with the regulations.Conclusion Three-way stopcocks are highly vulnerable to contamination during operative anesthesia.Regular sterile operations can effectively prevent and lower postoperative infection of the patients.
3. Professional certification system of infection prevention and control in the United States and its enlightenment to China
Chinese Journal of Hospital Administration 2019;35(9):785-788
The United States Certification Board of Infection Control and Epidemiology(CBIC)provides standardized measurements for all infection prevention and control professionals. It pursues a professional standard of excellence and aims to continuously improve their skills to ensure safe medical care of high quality for patients. We should learn from their certification system of infection prevention and control to accelerate the development and maturity of professional certification of infection prevention and control in China.
