Abstract：Objective To compare the effect of two disinfection methods of the needleless infusion connector. Methods Twenty-six clinical nurses in Haikou Hospital Affiliated to Xiangya Medical College of Central South University from January to March 2019 were selected as the research subjects, and all the 26 nurses participated in the control group and the observation group. The 0.2% Entoiodine cotton swabs were used by nurses in the control group to disinfect the needleless infusion connectors for 150 times, and the individually wrapped 4 cm×4 cm 75% alcohol cotton pads were used by nurses in the observation group to disinfect the needleless infusion connectors for 150 times. The disinfection operation time and use time of needleless infusion connectors, consumables costs, re-contamination after disinfection,clinical nurses′ satisfaction and willingness degrees were compared between the two groups. Results The proportions of non-contamination after disinfection and re-contamination after disinfection in the control group and the observation group were 88.0%, 12.0%, 94.0% and 6.0%, respectively. The proportion of non-contamination after disinfection in the observation group was higher than that in the control group, and the difference was statistically significant (P＜0.05). The consumables cost and disinfection operation time of the control group and the observation group were(61.6±1.62) yuan and (36±3) s，and (37.8±0.82) yuan and (16±1) s, respectively. The consumables cost of the observation group was lower than that of the control group, and the disinfection operation time of the observation group was shorter than that of the control group, the differences were statistically significant (P ＜0.05). The degrees of satisfaction and willingness of nurses in the control group and the observation group were 46.0%, 46.0%, 92.0% and 92.0% respectively. The degrees of satisfaction and willingness of nurses in the observation group were higher than those of nurses in the control group, and the differences were statistically significant (P＜0.05). Conclusion Using the 4 cm×4 cm 75% alcohol cotton pad to maintain the needleless infusion connector is convenient for nurses to disinfect the connector grooves with the rubbing method and effectively remove the residual microorganisms in the connector grooves. It can also shorten the disinfection operation time, save the consumables cost, effectively reduce the recontamination rate after the disinfection of needleless infusion connectors, and improve the satisfaction and willingness of clinical nurses, which is worthy of clinical promotion and application.
