| Objective: To investigate the hemodynamic effect of neuromuscular electrical stimulation (NMES) on preventing the formation of deep vein thrombosis (DVT) in the elderly patients with long-term bed rest. Methods: A total of 40 patients were randomly divided into the experimental group and the control group. Both groups were given routine care to prevent DVT. The experimental group received NMES on the basis of routine care, and the control group received sham-NMES on the basis of routine care. Before and after 14 days of the intervention, color Doppler ultrasound was performed to measure peak flow velocity and lumen diameter of the common femoral and popliteal veins bilaterally in both lower extremities. The venous stasis index was calculated according to the velocity and diameter. The D-dimer level was detected and the lower leg circumference was measured. Results: After 14 days of intervention, the peak flow velocity of bilateral common femoral vein and left popliteal vein increased, the left popliteal vein diameter decreased as compared with those before intervention (P<0.05), and the stasis index of bilateral common femoral vein and popliteal vein decreased as compared with that before intervention (P<0.05). In the control group, the peak flow velocity of bilateral common femoral vein and popliteal vein and the peak diameter of bilateral common femoral vein and popliteal vein had no statistically significant difference before and after intervention, and the stasis index of left common femoral vein and left popliteal vein after intervention increased as compared with that before intervention (P<0.05). The peak flow velocity and pipe diameter of bilateral common femoral vein and right popliteal vein in the study group were significantly increased as compared with those in the control group (P<0.05), and the stasis index of bilateral common femoral vein and popliteal vein in the study group was significantly decreased as compared with the control group (P<0.05). Conclusion: NMES can improve the peak flow velocity of the common femoral vein and popliteal vein of lower limbs and reduce the stasis index, which has the application prospect of preventing the formation of DVT. |
