Abstract:
Objective:To compare the disinfection effect of three-hole polypropylene infusion bottle stopper by central sterilization method and groove central sterilization method, and to explore the best method of three-hole polypropylene infusion bottle cap disinfection.
Methods:A total of 1 088 bottles of three-pore polypropylene infusion bottles from 10 hospitals in Panzhihua City and the surrounding areas of Chengdu were selected for disinfection, and the effects were compared by fluorescent powder tracing method and bacterial culture method respectively. The two methods were divided into two groups: bottle stopper Central Sterilization group and groove Central Sterilization group. Each nurse sterilized two groups of liquid.
Results:The total area of fluorescent powder residues after disinfection of 272 bottles of infusion bottles with different specifications M(P25, P75) was 0.26 (0, 2.51). The total area of fluorescent powder residues M(P25, P75) was 15 (8, 24). There were significant differences in the residual area of fluorescent powder between the two groups after liquid bottle disinfection (Z=-17.31, P<0.01). Thirty-four positive specimens of bacteria culture, 68 bacterial colonies and 158 bottles of infusion bottles were disinfected by central sterilization of 160 bottles. There were 15 positive samples and 30 colonies of bacteria cultured in the bottle disinfected by groove central disinfection method (χ2=2.773, P<0.05).
Conclusion:The groove center disinfection method is the best disinfection method for the bottle stopper of three-hole polypropylene infusion bottle.
