PICC care and functional exercise

Abstract:

Objective: A case-control study was conducted to elucidate the impact of application of nursing intervention based on intelligent grip strength system in patients with tumor peripherally inserted central catheter (PICC) on promoting functional exercise and life quality.

Methods: A total of 100 patients with tumor PICC treated in our hospital from April 2019 to April 2021 were enrolled. The patients were randomly assigned into control group and study group. The control group received routine nursing, and the study group received nursing intervention based on intelligent grip strength system.

Results: First of all, we compared the nursing satisfaction between the two groups: the study group was very satisfied in 43 cases, satisfactory in 6 cases, and general in 1 case, and the satisfaction rate was 100.00%, while in the control group, 29 cases were very satisfied, 10 cases were satisfied, 6 cases were general, and 5 cases were dissatisfied. The satisfaction rate was 90.00%. As such, the nursing satisfaction of the study group was higher compared to the control (P < 0.05). Secondly, we compared the average blood flow velocity per unit time of axillary vein at different moments. Before catheterization, there exited no significant difference (P > 0.05). The average blood flow velocity per unit time of axillary vein in the study group was faster compared to the control at different time points (P < 0.05). In terms of the average blood flow velocity per unit time of axillary vein at different time points between the two groups, there exited no significant difference before catheterization (P > 0.05). But 14 and 28 days after catheterization, the average blood flow velocity per unit time of axillary vein in the study group was better when compared to the control (P < 0.05). Comparing the incidence of catheter-related complications, the incidence of catheter-related complications such as redness and swelling, phlebitis, catheter occlusion, and catheter slip in the study group (12.00%) was lower compared to the control (60.00%) (P < 0.05). There was no significant difference in vascular diameter, peak blood flow velocity, and vascular pressure between the two groups before nursing (P > 0.05), but after nursing, the vascular diameter and peak blood flow velocity group were higher, and the vascular pressure was lower in the study (P < 0.05). Comparing the scores of functional exercise compliance, the scores of grip exercise compliance, exercise monitoring compliance, active help seeking compliance, exercise attention compliance, and the total score of compliance in the study group were higher compared to the control (P < 0.05). Finally, we compared the scores of life quality. Before nursing, there exhibited no significant difference between the two groups (P > 0.05). The scores of physiological function, psychological function, social function, and health self-cognition in the study group were lower when compared to control (P < 0.05).

Conclusion: The utilization of intelligent grip strength system can improve the functional exercise compliance of PICC patients, effectively facilitate the venous blood circulation of upper limbs, and strengthen the life quality, as well as reduce the incidence of catheter-related thrombosis. However, more multicenter, large sample, randomized controlled studies should be carried out to explore the impact of intelligent grip strength system on the long-term effect of functional exercise in patients with PICC.
