Objective To explore the effects of three different positions on using Baxter pump through Peripherally Inserted Central Catheter (PICC) tube continuous chemotherapy velocity. Methods 49 patients were performed a total of 180 cases of Baxter pump through PICC tube continuous chemotherapy. According to the positions they took during the time period of 7:00~21:00, they were divided into three groups: group 1 (supine), group 2 (sitting), group 3 (standing/walking position). Patients of each group were performed 60 cases to observe and record their chemotherapy infusion flow velocity. Results The results indicated that different positions have a significant impact on the flow velocity by using Baxter pump through PICC tube continuous chemotherapy. The error rates of group 1, group 2 and group 3 were 8.33%, 18.33% and 26.67% respectively; the flow velocity of group 1 was close to the set time, group 2 was slowly while group 3 was rapid. When compared among the three groups and inter-group, the differences were statistically significant: when compared among 3 groups, the x2 =14.23, P<0.01; when compared between group 1 and group 2, the x2 =13.55, P<0.01; when compared between group 1 and group 3, the x2 =10.36, P<0.01; and when compared between groups 2 and group 3, the x2 =10.55, P<0.01. Conclusion It is recommended that patients, who are using Baxter pump via PICC tube continuous chemotherapy, take the supine position as much as possible on the premise of not affecting daily life, so that the flow velocity of chemotherapy infusion time can be within the normal range to achieve optimum chemotherapy efficacy.%目的 探讨3种不同体位对使用百特泵经PICC管持续化疗流速的影响.方法 将49例患者共接受百特泵经PICC管持续化疗180例次,按其在7:00~21:00时间段主要采取的体位分为3组:平卧位(组1)、坐位(组2)、站立/行走位(组3),每组60例次,观察并记录各组泵注化疗流速.结果 采用不同体位对使用百特泵经PICC管持续化疗流速有明显的影响:组1、组2、组3的误差率分别是8.33%、18.33%和26.67%,组1与所设定时间最为接近,组2偏慢,组3则偏快.3组及组间比较,差异均具有统计学意义:3组比较x2=14.23,P<0.01;组1和组2比较x2=13.55,P<0.01;组1和组3比较x2=10.36,P<0.01;组2和组3比较x2=10.55,P<0.01.结论 建议使用百特泵经PICC管持续化疗患者在不影响日常生活的前提下尽量多采取平卧位,以使泵注化疗流速时间在正常范围内,以达到最佳的化疗药效.
