RESUMO
Objective To investigate the qualified rate of midwives’surgical hand disinfection and perineal in-cisional infection in parturients,so as to provide reference for reducing perineal incisional infection.Methods Data of 7 148 women who delivered naturally in an obstetrics department between January 2012 and December 2013 were collected,3 569 midwives who weren’t intervened in surgical hand disinfection between January and December 2012 were as control group,and 3 579 midwives who were intervened between January and December 2013 were as intervention group,the perineal incisional infection rate of parturients and qualified rate of midwives’hand hygiene of two groups were compared.Results There were no significant difference in maternal age,body mass index,un-derlying diseases,No.of vaginal delivery examination,delivery season,delivery lasting time,incision suture tech-nique,antimicrobial prophylaxis,and neonatal weight between intervention group and control group (all P>0.05). The qualified rate of midwives’surgical hand disinfection method increased from 19.31%(n=689)before interven-tion to 71.03%(n=2 542)after intervention,the difference was significant between two groups(χ2=752.58,P<0.05).Perineal incisional infection rate in intervention group was significantly lower than control group ([(0.28%, 10/3 579]vs [0.81%,29/3 569]),there was significant difference between two groups (χ2=9.36,P<0.05). Conclusion The improvement of qualified rate of midwives’hand hygiene can reduce perineal incisional infection rate of parturients.
RESUMO
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.
