Abstract:
Objective:To analyze the feasibility of free disinfection of central venous catheter infusion connector after using disposable disinfection caps.Methods:Using the convenient sampling method, a total of 132 patients who were hospitalized in the Department of Hematology of a Class Ⅲ Grade A hospital in Beijing from January to August of 2020 were selected as the research objects. According to the order of hospitalization, they were divided into the experimental group (group A) and the control group (group B) . Group A used disposable disinfection caps to connect the infusion connector, while group B repeatedly wiped the infusion connector for 15 s with 70%-80% alcohol cotton before infusion. According to infusion interval of 8 and 12 h and sampling timing, group A was divided into group A1-8 h and group A2-12 h, while group B was divided into group B1-8 h and group B1-12 h, with 33 cases in each group. Samples from infusion connectors of the 4 groups were collected for bacterial culture and bacterial inhibition on the surface of infusion connectors was compared.Results:There were 2 cases of detachment in A1-8 h group, 3 cases in A2-12 h group and 1 case in B2-12 h group. A total of 126 patients completed the study. A total of 18 patients in group A had bacteria at the infusion connector, which was more than 0 patients in group B, and the difference was statistically significant ( P<0.01) . In A1-8 h group, there was statistically significant difference in the presence of bacteria before and after using disinfection caps ( P<0.01) . There was no statistically significant difference in the presence or absence of bacteria in the infusion connector before and after the use of the infusion caps in the A2-12 h group ( P>0.05) . Conclusions:The disinfection effect of the disposable infusion connector disinfection cap is not the same as that of the disposable alcohol cotton pad disinfection method, but it can inhibit the growth of bacteria on the infusion connector surface within 8 h.
