ABSTRACT
Objective:To study the clinical application of hanging moxibustion in intervention of deep venous thrombosis (DVT) of lower extremity after intertrochanteric fracture of femur, in order to provide theoretical basis for the clinical application of suspension moxibustion.Methods:By adopting a controlled clinical trial method, a total of 100 patients with femoral intertrochanteric fracture who came to Keqiao District Hospital of Traditional Chinese Medicine, Shaoxing City, Zhejiang Province for orthopaedic surgery from January 2021 to September 2022 were selected by convenient sampling method and randomly divided into the control group and the observation group, 50 cases in each group. The control group was given routine nursing intervention, and the observation group was given the traditional Chinese medicine nursing intervention of hanging moxibustion on the basis of the control group. The changes of coagulation function indexes, hemorheology indexes, hemodynamics, the swelling degree score of the affected limb, and the Visual Analogue Scale (VAS) of the affected limb pain in the two groups of patients with intertrochanteric fracture before and 14 days after the intervention, and the incidence of lower extremity deep venous thrombosis (DVT) in the two groups after 1 d, 3 d, 7 d, and 14 d of intervention were observed and recorded.Results:After 14 days of intervention, D-dimer, fibrinogen and prothrombin time in the observation group were (380.64 ± 41.78) μg/L, (4.51 ± 0.49) g/L and (10.46 ± 1.04) s, respectively, which were better than those in the control group (464.91 ± 46.81) μg/L, (4.82 ± 0.56) g/L and (12.85 ± 1.12) s with statistical difference ( t=9.50, 2.95, 11.06, all P<0.05). After 14 days of intervention, the whole blood low tangential viscosity, whole blood high tangential viscosity and plasma viscosity in the observation group were (8.34 ± 0.42), (3.72 ± 0.28) and (1.21 ± 0.18) mPa/s, respectively, which were significantly lower than (8.90 ± 0.46), (4.13 ± 0.26) and (1.53 ± 0.22) mPa/s in the control group ( t=6.36, 7.59, 7.96, all P<0.05). After 14 days of intervention, the postoperative blood flow, maximum blood flow velocity and average blood flow velocity in the observation group were (1.89 ± 0.26) L/min, (31.57 ± 3.29) cm/s, (34.41 ± 3.62) cm/s, which were significantly higher than (1.45 ± 0.21) L/min, (24.18 ± 2.85) cm/s, (27.96 ± 3.15) cm/s in the control group ( t=9.31, 12.01, 9.50, all P<0.05). After 14 days of intervention, the total incidence of lower limb DVT in the observation group was 2.00%(1/50) , lower than 24.00%(12/50) in the control group, the difference between the two groups was significant ( χ2=10.70, P<0.05). Conclusions:Suspended moxibustion can significantly improve the coagulation function, hemorheology, hemodynamics, swelling and pain of the affected limb in patients with postoperative intertrochanteric fracture of the femur, and reduce the occurrence of DVT in the lower extremity. It is recommended to be widely used in clinical practice.
