Effect of auricular point pressure seed combined with low frequency electric acupuncture point stimulation on prevention of deep vein thrombosis after hip and knee surgery
[Objective]To analyze the preventive effect of auricular point pressure seed combined with low-frequency electric acupuncture point stimulation on the formation of deep vein thrombosis(DVT)after hip and knee surgery.[Methods]The 120 patients who underwent hip and knee surgery at the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine from August 2018 to August 2023 were selected and randomly divided into two groups using a random number table method,with 60 patients in each group.The control group received treatment with rivaroxaban,while the observation group received low-frequency electrical acupoint stimulation combined with ear acupoint seed pressing treatment on the basis of the control group.The therapeutic effects of both groups were evaluated 7 days after treatment.The thromboelastography(TEG)parameters,coagulation function indicators,difference in limb circumference,degree of limb swelling,visual analogue self-assessment scale(VAS)scores,and incidence of DVT were compared between the two groups.[Results]The coagulation index(CI),maximum amplitude(MA),and rate of blood clot aggregation after treatment(α angle)of the observation group were lower than those of the control group after treatment(P＜0.05).The coagulation time(K)and reaction time(R)of the observation group were higher than those of the control group after treatment,and the difference was statistically significant(P＜0.05).After treatment,the levels of D-dimer(D-D)and fibrinogen(FIB)in the observation group were lower than those in the control group,with statistical significance(P＜0.05).The partial prothrombin time(APTT)and prothrombin time(PT)in the observation group were higher than those in the control group,with statistical significance(P＜0.05).The difference in circumference of the thighs and calves in the observation group after treatment was lower than that in the control group,and the difference was statistically significant(P＜0.05).The degree of swelling in the affected limbs of the observation group was milder than that of the control group,and the difference was statistically significant(P＜0.05).The VAS score of the observation group after treatment was lower than that of the control group,and the difference was statistically significant(P＜0.05).The incidence of DVT in the observation group(1.67%)was lower than that in the control group(13.33%),and the difference was statistically significant(P＜0.05).[Conclusion]Auricular point pressure seed combined with low-frequency electric acupuncture point stimulation can effectively improve the coagulation function of the patients with hip and knee surgery,relieve the symptoms of limb swelling and pain,narrow the circumference difference of the affected limb,and reduce the incidence of DVT.
