OBJECTIVE To evaluate the efficacy and safety of low molecular weight heparin(LMWH) in prophylaxis of postoperative deep vein thrombosis (DVT) following hip and knee surgery. METHODS From April 1997 to October 1998, 46 patients undergoing hip and knee orthopedic procedures were randomized into 2 groups for studying. The following eligibility criteria were applied: age over 40 years old, no recently history of venous thromboembolism (over 3 months), normal result of preoperative hemostasis test and normal result of Doppler examination of the lower extremities. One group was control group and the other group received subcutaneously a low molecular weight heparin(Fraxiparine) with anti-factor X, activity of 41 IU/kg.day for three days, then 62 IU/kg.day from the 4th day to 10th day. All patients had venegraphy performed in the operated leg at 4 to 7 days after surgery. RESULTS eight patients(34.8%) developed DVT in the control group of 23 patients and 1 patient (4.3%) in the experimental group, also of 23 patients(P lt; 0.05). Two groups had no any bleeding complications. CONCLUSION The low molecular weight heparin is safe and effective in preventing postoperative deep vein thrombosis in patients following hip and knee surgery.
【摘要】 目的 评价葛根素注射液（PI）联合低分子肝素（LMWH）治疗不稳定型心绞痛（UAP）的疗效和安全性。 方法 计算机检索中国生物医学文献数据库（CBM）、中国期刊全文数据库（CNKI）、中文科技期刊全文数据库（VIP-维普）、万方-数字化期刊全文库，纳入在常规治疗上加用PI和LMWH对比单纯常规治疗的随机对照试验（RCT），对纳入研究进行质量评价和Meta分析。 结果 共纳入21个RCT，均为C级文献。Meta分析结果显示，在临床症状疗效显效率、心电图疗效显效率和有效率指标方面，两组差异有统计学意义:RR（95%CI）分别为:1.63（1.48，1.79）、1.57（1.34，1.83）及1.28（1.10，1.49）。 结论 基于上述证据，在常规治疗UAP上加用PI和LMWH疗效优于常规治疗。【Abstract】 Objective To evaluate the effect of the puerarin injection (PI) combined with low molecular weight heparins (LMWH) on unstable angina pectoris (UAP). Methods Randomized controlled trials (RCT) of PI combined with LMWH treating UAP were gathered from CBM, CNKI, VIP, and Wanfang data bases; and study quality was evaluated and the Meta-analysis was carried out. Results A total of 21 RCT were identified, of which all were in graded C. According to Meta-analysis, the differences of the clinic excellent rate, electrocardiogram excellent rate and effective rate between the two groups were significant; the RR (95%CI) were: 1.63 (1.48, 1.79), 1.57 (1.34, 1.83), and 1.28 (1.10, 1.49). Conclusion Based on the evidence recently, PI and LMWH adding is better than ordinary treatment for UAP.
Objective To analyze the effect of arteriovenous impulse system (AVIS) combined with lowmolecular-weight heparins calcium (LMWHC) for prophylaxis of deep vein thrombosis (DVT) following total knee arthroplasty (TKA). Methods From March 2006 to March 2008, 76 cases of osteoarthritis patients (76 knees) accepted TKA, including 25 males and 51 females with an average age of 66.6 years (range, 58-79 years). The affected knees were left side in 41 cases and right side in 35 cases. They were randomly divided into experimental group and control group before surgery. Then LMWHC and rehabil itation training were routinely given in two groups before and after surgery. However, only experimental group was treated with AVIS continually during the first four days and then two times a day for 30 minutes one time during 5-7 days. At 7 daysd after operation, color Doppler ultrasound was used to detect the occurrence condition of DVT. Results Five cases (13.16%) had thrombosis of calf and recovered after treated with urokinase and salvia in the experimental group. Eleven cases had thrombosis of calf and 3 cases had thrombosis of whole low extremities (36.84%), and improved after treated with urokinase and salvia in the control group. There was significant difference in DVT incidencerate between two groups (P lt; 0.05). No pulmonary embol ism or death was found in both groups. Conclusion AVIScan effectively accelerate the venous blood return velocity, a combination of AVIS and LMWHC has a better effect in theprevention of DVT following TKA.
ObjectiveTo systematically evaluate the efficacy and safety of different low-molecular-weight heparins (LMWHs) in improving pregnancy outcomes in patients with recurrent abortion. MethodsThe PubMed, EMbase, Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from inception to July 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 16.0 software. ResultsA total of 25 RCTs involving 4 631 patients were included. Enoxaparin, dalteparin, nadroparin, and tinzaparin were included. The results of network meta-analysis showed that the live birth rate of the tinzaparin was higher than that of enoxaparin and dalteparin. The live birth rate in nadroparin was higher than that in enoxaparin and dalteparin. The cumulative sorting probability showed that tinzaparin ranked best for improving the live birth rate, nadroparin ranked best for reducing the miscarriage rate, and enoxaparin ranked best for reducing the preterm birth rate. ConclusionCurrent evidence suggests that tinzaparin and nadroparin may be the best choice for improving pregnancy outcomes in patients with recurrent abortion. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
目的探讨低分子肝素预防下肢静脉曲张术后深静脉血栓形成的临床效果。 方法将2011年1月至2013年12月期间于笔者所在医院行大隐静脉高位结扎＋分段剥脱术＋腔内激光闭合术的513例下肢静脉曲张患者随机分为2组：低分子肝素组238例，下肢静脉曲张术后采用低分子肝素预防性治疗；对照组275例，术后不采用任何抗凝药物。比较2组患者深静脉血栓形成和并发症发生情况。 结果低分子肝素组发生浸透敷料的出血14例（5.9%），切口出血或皮下血肿25例（10.5%），血小板减少1例（0.4%），肝功能异常2例（0.8%），无深静脉血栓形成发生；对照组发生浸透敷料的出血19例（6.9%），切口出血或皮下血肿27例（9.8%），肝功能异常2例（0.7%），深静脉血栓形成7例（2.5%），无血小板减少发生。2组患者浸透敷料的出血、切口出血或皮下血肿、血小板减少及肝功能异常发生率比较差异均无统计学意义（P＞0.05），但低分子肝素组深静脉血栓形成的发生率低于对照组（P＜0.05）。术后获访487例，随访时间为4～12个月，平均10个月。其中低分子肝素组获访225例，对照组获访262例。获访患者随访期间发生下肢静脉曲张复发9例（低分子肝素组4例，对照组5例），隐神经损伤11例（低分子肝素组5例，对照组6例），无远期下肢深静脉血栓形成病例。2组患者的下肢静脉曲张复发率和隐神经损伤发生率比较差异均无统计学意义（P＞0.05）。 结论采用低分子肝素预防下肢静脉曲张术后下肢深静脉血栓形成具有良好的临床效果和安全性，值得临床推广应用。
ObjectiveTo systematically review the safety of low molecular weight heparin (LMWH) in pregnancy. MethodsPubMed, EMbase, The Cochrane Library, WanFang Data, VIP, and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) and cohort studies on the safety of LMWH in pregnancy from inception to March 30th, 2020. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 77 RCTs and 13 cohort studies were included. The results of meta-analysis showed that LMWH increased the incidence of postpartum hemorrhage (RR=1.50, 95%CI 1.00 to 2.25, P=0.05). However, there was no significant difference. The incidence of hematological adverse events was different from the results of RCTs and cohort studies. The results of RCT subgroup analysis showed that LMWH increased ecchymosis at the injection site (RR=1.60, 95%CI 1.24 to 2.08, P=0.000 4). However, the incidence of overall skin system adverse events did not increase significantly. LMWH reduced the incidence of cardiovascular adverse events (RR=0.18, 95%CI 0.07 to 0.46, P=0.000 3). LMWH failed to increase the occurrence of fetal congenital malformations, digestive system, central nervous system, skeletal system, and systemic adverse events. ConclusionsCurrent evidence suggests that LMWH is relatively safe to use during pregnancy. However, whether it increases postpartum hemorrhage and hematological adverse events is unclear. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
ObjectiveTo systematically review the efficacy and safety of different low-molecular-weight heparins (LMWHs) for prevention of thromboembolic events in patients with atrial fibrillation (AF).MethodsPubMed, The Cochrane Library, EMbase, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized clinical trials (RCTs) on efficacy and safety of different low-molecular-weight heparins (LMWHs) in preventing thrombotic diseases in patients with atrial fibrillation from inception to March 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, meta-analysis was performed by using Stata 16.0 software.ResultsA total of 11 RCTs involving 7 400 patients who were treated with enoxaparin, dalteparin, or tinzaparin to prevent thromboembolic events were included. The results of network meta-analysis showed that: in patients with AF and perioperative AF patients, there were no statistical differences in the incidence of stroke, TIA, major bleeding, minor bleeding, and all-cause mortality caused by dalteparin, enoxaparin, and tinzaparin. Furthermore, the surface under the cumulative ranking area (SUCRA) showed that enoxaparin was superior for prevention of stroke and TIA than dalteparin and tinzaparin. As for major bleeding, minor bleeding, and all-cause death, dalteparin treatment was superior than enoxaparin.ConclusionsCurrent evidence showed enoxaparin to be a viable option for high ischemic risk AF patients requiring LWMH treatment, while dalteparin to be a viable option for those with bleeding high risk. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
