ABSTRACT

Objective:

To evaluate the curative effect of Fumai Zhuyu Decoction on deep vein thrombosis (DVT) after orthopedic surgery.

Methods:

According to random method, 90 patients with DVT after orthopedic surgery who met inclusion criteria in the hospital were divided into two groups between January 2018 and December 2020, 45 cases in each group. Both groups were given DVT catheterization for thrombolysis. After that, control group was given subcutaneous injection of low molecular weight heparin calcium, while observation group was additionally treated with Fumai Zhuyu Decoction. All were continuously treated for 14d. Before and after treatment, scores of TCM syndromes were evaluated. The coagulation response time (R), clotting time (K), clotting angle (α) and maximum strength of blood clotting (MA) were detected by full-automatic thromboelastometry analyzer. The levels of serum IL-6 and CRP were detected by ELISA. The hematocrit (Hct) was calculated according to red cell casts and whole blood height. The adverse reactions were recorded. And the clinical curative effect was evaluated.

Results:

The differences in total response rate between observation group and control group were statistically significant [82.2% (37/45) vs. 62.2% (38/45); χ2=4.49, P=0.034]. After treatment, scores of affected limb pain, dark encrusted skin and affected limb swelling in observation group were significantly lower than those in control group ( t values were 7.26, 7.14, 6.88, respectively, all Ps<0.001). After treatment, R [(6.12±0.86) min vs. (5.45±0.56) min, t=3.58] and K [(2.24±0.45) min vs. (1.72±0.42) min, t=4.63] in observation group were significantly longer than those in control group ( P<0.01), α [(51.69±2.23)° vs. (54.23±2.42)°, t=4.23] and MA [(51.58±3.62) min vs. (54.58±3.53) min, t=3.25] were significantly lower than those in control group ( P<0.01), and levels of serum IL-6, CRP and Hct were significantly lower than those in control group ( t values were 2.66, 2.96, 7.58, respectively, all Ps<0.01). During treatment, differences in incidence of adverse reactions between observation group and control group were statistically significant [6.7% (3/45) vs. 22.2% (10/45); χ2=4.41, P=0.036].

Conclusion:

The Fumai Zhuyu Decoction can reduce blood viscosity, prevent thrombosis and improve clinical curative effect in patients with DVT after orthopedic surgery.
