摘要目的:探讨基于知信行（KAP）的上肢功能锻炼在PICC置管肿瘤化疗患者中的应用效果。方法:采用便利抽样法，选取2021年1—7月盐城市第一人民医院肿瘤科收治的90例PICC置管肿瘤化疗患者为研究对象，根据随机数字表法将其分为干预组和对照组，各45例。对照组采用常规护理方式，干预组在对照组的基础上给予基于KAP的上肢功能锻炼方案。比较两组静脉血栓事件、PICC相关并发症及自我管理能力。结果:置管14、21、28 d后，干预组上肢静脉血栓事件发生低于对照组，差异有统计学意义（ P<0.05）；干预组的导管相关并发症发生事件与对照组比较，差异无统计学意义（ P>0.05）。干预组的自我管理能力得分高于对照组，差异有统计学意义（ P<0.05）。 结论:基于KAP的上肢运动有利于降低静脉血栓发生率，提升患者的自我管理能力水平。

abstractsObjective:To explore the effect of upper limb function exercise based on knowledge, attitude and practice (KAP) in cancer chemotherapy patients with peripherally inserted central catheter (PICC) .Methods:From January to July 2021, convenience sampling was used to select 90 cancer chemotherapy patients with PICC in the Oncology Department of the Yancheng First People's Hospital as the research object. According to the random number table method, the patients were divided into the intervention group and the control group, 45 cases in each. The control group received routine nursing, and the intervention group carried out the upper limb function exercise based on KAP on the basis of the control group. PICC-related complications and self-management ability were compared between the two groups.Results:After 14, 21, and 28 days of catheterization, the incidence of upper limb venous thrombosis was lower than that in the control group, and the difference was statistically significant ( P<0.05) . There was no significant difference in the incidence of catheter-related complications between the intervention group and the control group ( P>0.05) . The self-management ability score of the intervention group was higher than that of the control group, and the difference was statistically significant ( P<0.05) . Conclusions:KAP-based upper limb exercise can prolong APTT and PT in cancer patients with PICC, which is beneficial to improve the axillary vein blood flow rate and average blood flow rate in cancer patients with PICC, reduce the incidence of venous thrombosis and the self-management ability of patients.
