Abstract：Objective To investigate the effectiveness of risk-based care thinking in preventing lower extremity venous thrombosis in patients undergoing continuous hemodialysis. Methods Ninety-two patients who received continuous hemodialysis treatment in the Renal Disease Intensive Care Unit of Jiangsu Provincial People’s Hospital from October 2018 to September 2021 were selected for the study. The envelope method was used to divide the patients into control group and observation group, with 41 cases in each group. Both groups implemented conventional nursing interventions, while the observation group implemented risk-based nursing thinking on this basis. Before and a week after the intervention, venous blood flow velocity, lower extremity swelling, and incidence of lower extremity venous thrombosis were observed and compared. Results After a week of intervention, the whole blood viscosity low cut, whole blood viscosity medium cut, whole blood viscosity high cut, and plasma viscosity in both groups were lower than before the intervention, while those of the observation group were lower than those in the control group, and the differences were statistically significant (P ＜ 0.05). After a week of intervention, the blood flow velocity in femoral and popliteal veins in both groups were higher than before the intervention, while those of the observation group were lower than those in the control group, and the differences were statistically significant (P ＜ 0.05). The incidence of limb swelling and deep vein thrombosis in the observation group was lower than that in the control group, and the difference was statistically significant (P ＜ 0.05). Conclusion Implementing risk-based care thinking for continuous hemodialysis patients accelerates lower extremity venous blood flow and prevents lower extremity venous thrombosis and limb swelling.
