Observe The Clinical Curative Effect Of Supplementing Qi And Activating Blood Circulation(益气活血法)in Preventing Deep Veins Thrombosis (DVT)after Hip Surgery

Objective:to study the effect and its mechanism of action of the method of supplementing Qi and activating blood circulation (益气活血法) in preventing deep vein thrombosis (DVT) after hip replacement.Method:This article were retrospectively analyzed of the 102 patients met study criteria in affiliated hospital of Chengdu University of Traditional Chinese Medicine orthopedic hospital in March,2013--March,2015.Clinical data were obtained through the medical record to retrieve,and patients were randomly divided into two groups according to patients with medication:preventing group(Group A,52 patients)and control group(Group B,50 patients). Group A,52 patients, who were given Buyang Huanwu Decoetion (补阳还五汤)and Rivaroxaba for Prevention of DVT; Group B,50 patients, who Were given Rivaroxaba for Prevention of DVT.The parameters, such as the incidence of DVT, bleeding condition,blood transfusion, femoral venous blood flow, the content of hemoglobin (HGB), platelet count (PLT) count, prothrombin time (PT)and part of the activated partial thromboplastin time(APTT), Harris hip score, were evaluated respectively.Results:Two groups of patients age, gender, disease types, with onset, left and right sides, operation time and so on general data comparison, there were no statistically significant difference (P>0.05).Two groups of post-operative DVT incidence is 6. 90% (7/102), in which the Group A 7.69%(4/52), in the Group B6.0% (3/50), two group difference was not statistically significant (P>0.05).The mean draining liquid in the group A (263.75 ± 105.02) ml, was less than that in the group B(323.00 ± 105.06)ml, there was a significant difference between the two groups (p<0.05).The hidden blood lossin the group A (356.45 ± 105.23) ml, was less than that in the group B((427.50 ± 105.13) ml, there was a significant difference between the two groups (p<0.05).16 cases of transfusion patients in the Group A, transfusion rate was 16/52≈31%,26cases of transfusion patients in the Group B, transfusion rate 26/50≈52%, and compared the two groups was statistically significant (p<0.05).the mean content of femoral venous blood flow velocity after the surgery recovered more quickly in Group A than that of Group B(P<0.05). Comparing with HGB and PLT in the preoperative and postoperative day1 of two groups without blood transfusion in patients, there was no statistical significance difference (P> 0.05), but the group A is higher than the group B after 7 days to compare(P< 0.05).Two groups of patients of PT, APTT,in preoperative and postoperative 7 days more differences had no statistical significance (P> 0.05).Harris hip score of the group A was higher than the group B before hospital discharge (P<0.05)Conclusion:Method of supplementing Qi and activating blood circulation could be effective in preventing the risk of DVT of lower limbs, and reduces the hidden blood loss following hip replacement, decrease transfusion rates.
