Three different preoperative cleaning methods for preoperative disinfection effect

OBJECTIVE To compare the different cleaning methods of preoperative skin disinfection effect,so as to prove the necessity of preoperative antibacterial bath.METHODS From animal experiments,skin field experiment and clinical observation statistics,three methods of cleaning were compare.RESULTS Effect of killing by using antibacterial soap to clean followed by disinfection for common skin bacteria and pathogenic bacteria compared with soap water clean group and wash group were significantly improved.Simulation experiments on animals,antibacterial soap washing group in postoperative healing could have no infection with all surgery wound normal healed and no adverse reaction occurred,and there were a small amount of infection in the other two groups.Simulation experiments on human skin,soap water washing and antibacterial soap washing were both better than only use clean water considering disinfection effect.The disinfection effect of antibacterial soap after 5hcleaning on the skin surface still had an effect,and the disinfection effect is the best.Clinical observation showed that implementation of preoperative antibiotic bath the infection rates could go down a bit,from 3.8%to 0.9%.CONCLUSION Preoperative antibiotic bath can improve the effect of preoperative skin disinfection,which is a simple economic and feasible method of reducing surgical site infection.
