The results of meta-analysis showed that various forms of upper limb movements could effectively decrease the incidence of venous thrombosis in the patients with PICC [<em>RR</em> = 0.23, 95% <em>CI</em> (0.16, 0.33), <em>P</em> < 0.01], upper limb movements could effectively improve the mean blood flow velocity of basilic vein [<em>MD</em> = 1.65, 95% <em>CI</em> (1.19, 2.11), <em>P</em> < 0.01]. <strong>Conclusion:</strong> Upper limb movements can effectively decrease the incidence of phlebothrombosis and improve the mean flow velocity of basilic vein in the patients undergoing PICC. Other forms of physical prevention methods need to be further studied due to insufficient sample size.展开更多
