ObjectiveTo compare the effects of povidone iodine handwashing with brush and brush-free handwashing on the hand skin condition of nurses in operation room. MethodA random sampling method was used to choose 150 nurses from the operation room of a grade-3 class-A hospital as our study subjects from June 2013 to December 2014. They were randomly divided into control group and study group according to the random number table with 75 in each. The control group used the traditional povidone iodine handwashing with brush, while the study group applied brush-free handwashing method. Then, we compared the hand skin condition and disinfection effect of these two kinds of handwashing methods. ResultsThe control group had dry skin in 34 nurses (45.3%), dry desquamation in 9 (12.0%), tight feeling in 51 (68.0%), and allergy in 5 (6.7%). The study group had dry skin in 19 nurses (25.3%), dry desquamation in 0 (0.0%), tension in 21 (28.0%), and allergy in 0 (0.0%). The differences between the two groups were statistically significant (P<0.05). ConclusionsThe brush-free handwashing method is able to achieve the requirements of surgical hand disinfection, and can protect the skin of nurses in operation room.
Objective To systematically review the efficacy of chlorhexidine versus povidone iodine in the prevention of wound infections after surgeries by meta-analysis. Methods All randomized controlled trials comparing these two disinfectants were searched from databases of PubMed, The Cochrane Library (Issue 3, 2016), EMbase, WanFang Data, VIP and CNKI from inception to August 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2 software. Results A total of 14 randomized controlled trials were included. The results of meta-analysis showed that the chlorhexidine group had significantly lower rates in any surgical site infection (RR=0.71, 95% CI 0.58 to 0.88,P=0.001) and superficial incisional infection (RR=0.66, 95% CI 0.48 to 0.91,P=0.01) when compared with povidone iodine group. However, there were no significant differences in deep incisional infection (RR=0.51, 95% CI 0.23 to 1.11,P=0.09) and organ-space infection (RR=0.97, 95% CI 0.53 to 1.76,P=0.92) between the two groups. Furthermore, subgroup analysis revealed differences in any surgical site infection and superficial incisional infection could only be found in surgeries possibly contaminated. Conclusion Chlorhexidine may be superior in decreasing the incidence of infection in probably contaminated surgery.
