- Abstract: Objective To assess the air disinfection effects of air purification equipment vs ultraviolet radiation for interventional room and discuss their clinical application values. Methods Air purification equipment and ultraviolet radiation were applied individually for the same time to achieve the air disinfection of interventional room. Air bacteria were collected with plates before and after air disinfection, thereby evaluating the air disinfection effects. After the air disinfection with two kinds of methods, the postoperative infection rates of 5 830 patients who were treated in the Third Affiliated Hospital of Guangzhou Medical University from January 2015 to December 2016 were respectively analyzed. Results After the disinfection treatment for 24 months, ultraviolet radiation and air purification equipment had a sterilizing rate of 85.04% (283.1/332.9) and 83.72% (283.05/338.1) against air bacteria in interventional room. The number of air bacteria rates after the disinfection with air purification equipment and ultraviolet radiation were (43.69±23.08) cfu/m3 and (45.87±18.13) cfu/m3, respectively, and the postoperative infection rates were 0.49%(15/3 050) and 0.29%(8/2 780). No significant difference was found between air purification equipment and ultraviolet radiation regarding sterilizing effect, number of air bacteria and postoperative infection rate (P>0.05). Conclusion Air purification equipment which has a disinfection effect similar to that of ultraviolet radiation should be the first choice for the disinfection of interventional room, because it can be used continuously and throughout the operation and is harmless to human.
