Objective:To investigate the effect of ultraviolet light combined with moxa fumigation on air disinfection in hemodialysis room. Methods:The hospital hemodialysis room was selected as the environment for the test, and the air samples and the dialysis patients collected in this environment were used as experimental group. Conventional ultraviolet disinfection and moxa fumigation were used. The adjacent hospital hemodialysis room similar to the hospital's hemodialysis internal environment was selected as the control environment, and the air samples and dialysis patients collected in this environment were served as control group. The room was routinely disinfected with ultraviolet light. Samples were taken 3 times a month,i.e., at the beginning, in the middle and at the end of the month. The sampling time was at 9:00 and 16:00 and the samples were taken with >30 m2 5-point sampling method.The number of bacteria in each time period was analyzed. One hundred and sixty dialysis patients in each group were selected as observation subjects, and the occurrence of infection in the two groups was recorded. Results:At 9:00, the total number of bacterial colonies in the experimental group was significantly lower than that in the control group, while the total number of colonies in both groups increased significantly at 16:00, and the total number of colonies in the experimental group was significantly lower than that in the control group (P<0.05). Three cases of dialysis patients in the experimental group were infected, which was significantly lower than 12 cases in the control group. The difference was statistically significant (P<0.05). The incidence of respiratory infection in the experimental group was significant lower than that in the control group (P<0.05). Conclusion:Ultraviolet light combined with moxa fumigation can significantly improve the air disinfection effect in the hemodialysis room, reduce the incidence of infection in dialysis patients, and is suitable for air disinfection in the hemodialysis room.
