研究目的:

本研究旨在探讨心脏瓣膜置换术后早期不同的桥接抗凝治疗方法。  

Objectives of Study:

The objective of this study was to assess different bridging anticoagulation therapy early after heart valve replacement in Chinese patients.

药物成份或治疗方案详述:

肝素和低分子量肝素(依诺肝素) 桥接抗凝治疗在术后第1天开始。每日静脉注射肝素25 IU/kg, QID或每日皮下注射LMWH,剂量4000 IU, BID。术后第1天或第2天拔除气管插管,给予华法林口服,起始剂量为3mg。桥接抗凝剂被给予直到INR值连续2天在目标范围内。 

Description for medicine or protocol of treatment in detail:

UFH and LMWH (enoxaparin) Our postoperative bridging anticoagulation therapy was started on postoperative day 1. Intravenous UFH injection per day at a dose of 25 IU/kg, QID. Subcutaneous LWMH injection per day at a dose of 4,000 IU of anti-Xa, BID. Oral warfarin, starting dose 3mg, was given as soon as the patients were extubated on the first or second postoperative day. Bridging anticoagulants were given until the international normalized ratio (INR) was within the target range for 2 consecutive days 

纳入标准:

Inclusion criteria

排除标准:

孕妇、近期的神经事件、术前或术后严重肾功能不全(血肌酐>150umol/L)、透析患者、主动脉夹层、恶劣的围手术期状态、行主动脉内气囊反搏、术后气管插管时间超过48小时、术后低分子量肝素(LMWH)桥接抗凝时间少于2天。

Exclusion criteria:

pregnant, critical perioperative state, recent neurologic event, preoperative or postoperative severe renal insufficiency (serum creatinine>150umol/L), dialysis, aortic dissection, intraaortic balloon counterpulsation, duration of intubation of more than 48 hours, patients who used LMWH for less than 2 days after surgery.
