RESUMO
OBJECTIVE To investigate the appropriate time of changing Ke Lai Fu infusion connector of central venous infusion catheter.METHODS The patients were selected from Internal Oncology Dept in our hospital based on certain criteria,and divided these patients with central venous infusion catheter into 4 groups.The new infusion connector of their central venous catheter was changed every 7 days,10days,15 days and 30 days etc.The replaced infusion connectors were rinsed by normal saline and their residual flush liquids were sent for bacterial culture.The group that their bacterial culture of residual flush liquids was negative was determined as the best changing days of infusion connectors.RESULTS The bacterial culture positive rates of Ke Lai Fu infusion connectors which were renewed every 7 days,10 days,15 days and 30 days,were 0,8.1%,10.3%and 29.7%,respectively.The best renewing days of connector was 7 days.CONCLUSIONS This result of the study provides a valuable guidance for the proper application of infusion connectors and effectively prolonging the indwelling days of central venous infusion catheter;therefore it can decrease hospital infection rate.
