Maintenance of interval time for intravenous infusion port implanted patients during off-treatment period

Abstract

Objective To explore the effect of maintenance of interval time on catheter blockage and infection for intravenous infusion port patients during the off-treatment time. Methods A total of 100 patients with implanted ports, who drew blood well every time, bolus fluently and had informed consent, were divided into experimental group and control group by random number table method on average. The maintenance carried once in the control group every 4 weeks, while it happened in the experimental group every 12 weeks. We compared the catheter blockage and infection between two groups. Results There had no catheter completely block, Ⅲ grade catheter block and infection in the two groups during the 72 weeks, but Ⅰand Ⅱ grade blockage happened. In the experimental group, there was 3 patients having I grade catheter block, and that of the control group was 2 with no statistically significant difference between two groups (χ2=0.211, P>0.05). In the experimental group, there was 1 patients had Ⅱ grade catheter block, and that of the control group was 2 with no statistically significant difference between two groups (χ2=0.344, P>0.05). Conclusions The intravenous infusion port patients had no correlation between the length of maintenance and blockage with infection. The maintenance carried once every 4 weeks is easily accepted for patients. Key words: Implanted intravenous infusion port; Off-treatment time; Catheter maintenance
