研究设计:

Study design:

Parallel 

研究目的:

1. 通过单纯停药以及不同途径给予维生素K1治疗的随机对照试验,以期发现华法林抗凝过度且无出血的最佳处理方案。 2. 观察无出血的抗凝过度(INR4.5-10)者华法林相关基因多态性突变情况。  

Objectives of Study:

1. A randomized controlled trial of vitamin K1 therapy with simple withdrawal and different approaches was conducted to find the best treatment scheme for excessive anti-coagulation of warfarin without bleeding. 2. Warfarin related gene polymorphism was observed in patients with nonhemorrhagic hypercoagulability (inr 4.5-10).

药物成份或治疗方案详述:

本研究为干预性随机对照实验,按照纳入及排除标准纳入受试者,所有符合标准的门诊患者均收入院治疗,予以单纯华法林或停华法林+维生素K1 2.5mg治疗,维生素K1给药途径分为静脉、口服、肌肉注射三种方式,即处理抗凝过度方法为四种且随机的,使用维生素K1治疗的受试者停药一次,若用药24小时后INR 2.5-4.0,则继续停药至INR降至治疗范围;若用药24小时后INR大于4.0,则继续追加维生素K1 2.5mg。所有受试者当INR≦2.5时,适当下调华法林剂量开始服药,调整药物剂量为在原口服剂量的基础上每天减少0.25或0.5片。为保证安全,静脉使用维生素K1的时候,需与生理盐水配成50ml,30分钟以上微量泵入,泵入前后监测患者生命体征,受试者用药后观察30分钟看是否有药物不良反应。 

Description for medicine or protocol of treatment in detail:

This was a prospective randomized controlled study. the patients who met the inclusion and exclusion criteria were enrolled in this study, and were randomly subdivided into four groups(suspended warfarin therapysuspended warfarin therapy + intravenous dose of 2.5 mg phytonadionesuspended warfarin therapy + oral dose of 2.5 mg phytonadione,suspended warfarin therapy + intramuscular dose of 2.5 mg phytonadione ).Warfarin was withheld for at least 24 hours after administration of phytonadione, and longer if the INR at 24 hours was still greater than 2.5. If the INR was between 2.5 and 4.0 after 24 hours of administering phytonadione, the warfarin continued to be withheld until the INR was reduced to the target range; If the INR is greater than 4.0 after 24 hours of administering phytonadione, the patient will continue to use 2.5mg vitamin K1 and omit warfarin. Warfarin therapy was restarted once the INR was in the target range (INR 1.5-2.5), as determined by the attending physician. Intravenous phytonadione (Suicheng Pharmaceutical Co., Ltd, 10-mg ampoules, Henan, China) was serially diluted in a 50-mL saline and infused over 30 minutes. Blood pressure and pulse were determined before and after infusion. Oral phytonadione was administered as a single phytonadione tablet (Brilliant Pharmaceutical Co., Ltd. Chengdu 10-mg; China).any adverse event during phytonadione administration was recorded. 

纳入标准:

年龄大于18周岁;机械瓣膜置换术后使用华法林抗凝治疗并长期使用INR监测,INR值于4.5-10.0,且无活动性出血或仅轻微出血;签署知情同意书。

Inclusion criteria

Patients enrolled in this study were those with warfarin anticoagulant therapy and long-term INR monitoring were used after mechanical valve replacement and INR value was 4.5-10.0, and who were free of any active bleeding or only slight bleeding, were over 18 years old, and who provided written informed consent.

排除标准:

INR检测超过12小时;预期寿命少于10天;妊娠或哺乳者;有需立即纠正INR的指针(如活动性出血,或需要手术,或其他侵入性操作);严重肝病(失代偿肝硬化Child-Pugh B、C级,肝性脑病,肝肾综合征,肝凝血病等);肾衰(血清肌酐大于150μm/L);1月内大出血或血栓栓塞;已知对维生素K过敏;有出血性疾病或者48小时内有溶栓治疗史;血小板计数小于50x109/L;地理环境限制不能完整随访。

Exclusion criteria:

INR determined more than 12 h before screening; predicted life expectancy less than 10 days; indication for the immediate normalisation of their INR; severe liver disease (Decompensated cirrhosis child-pugh grade B, grade C, hepatic encephalopathy, hepatorenal syndrome, hepatic coagulation disease, etc); major bleeding within the previous month; known allergy to vitamin K; known bleeding diathesis or thrombolytic treatment within 48 h of screening; inability to take oral medications; massive bleeding or thromboembolism within one month; platelet count of less than 50 x 109/L; and geographic inaccessibility.
