Objective: To discuss the effect of double-stranded quaternary disinfectant wipes and chlorine disinfectant of sterilizing the surface of the operating room, and provide the basis for the operating room to choose the right way to disinfect. Method: 50 cases of operating table, instrument table, shadowless were given 2000mg/L double-stranded quaternary disinfectant wipes and 500mg/L chlorine disinfectant, and the surface of them were sampled and cultured before disinfection and instant, 30 min, 1 h after disinfection. The number of bacterial colonies, sterilization rate and disinfection cost before disinfection and different time points after disinfection of the different disinfection methods were observed. Results: The number of bacterial colonies of operating table, instrument table, shadowless before disinfection were respectively (35.9 ± 2.6) cfu / cm2, (46.0 ± 2.9) cfu / cm2, (78.3 ± 6.4) cfu / cm2,and the number of instant, 30 min, 1 h after disinfection were significantly lower than before disinfection, the differences were statistically significant (P<0.05).The number of bacterial colonies of double-stranded quaternary disinfectant wipes at different time points after disinfection were significantly lower than chlorine disinfectant, the differences were statistically significant (P<0.05);Disinfection effect of Escherichia coli, Staphylococcus aureus using double-stranded quaternary disinfectant wipes were better than chlorine disinfectant. Cost of double-stranded quaternary disinfectant wipes every disinfection was 0.6 yuan, and was lower than 0.9 yuan of the chlorine disinfectant. Conclusion: When sterilizing the surface of the operating room, double-stranded quaternary disinfectant wipes and chlorine disinfectant both can achieve better results, but the former is superior to the latter, and the former has the advantages of lower cost, simple and convenient, and is worthy of popularization in operating room.
