研究目的: |
观察骨科围手术期内,不同时间注射低分子肝素(low molecular weight heparin, LMWH)对深静脉血栓(DVT)的预防效果,从而进一步准确掌握LMWH的具体给药时间和剂量,使抗LMWH的抗血栓效果最大化。 |
||||||||||||||||||||||
|
Objectives of Study: |
To observe the deep venous thrombosis (DVT) prophylactic effect of low molecular weight heparin (LMWH) injection administered at different times during perioperative period in orthopaedic surgery, so as to accurately master the specific administration time and dose of LMWH, and maximize the antithrombotic effect of LMWH. |

|
药物成份或治疗方案详述: |
1.髋部周围骨折组使用那屈肝素钙皮下注射。入院至术前12h使用低分子肝素1天1次治疗,术后12h后继续予低分子肝素1天1次至出院。 2.髋、膝关节置换组患者使用依诺肝素钠注射液皮下注射。术后12h后予低分子肝素1天1次至出院。 3.低分子肝素的预防剂量严格根据药品说明书。 4.本研究尽可能控制变量的差异,采用同质化治疗及管理。 5.根据患者分组安排患者的手术时间,使每个患者在术后12-24h内注射低分子肝素。 6.医嘱离院为研究正常终点;如期间患者出现DVT、静脉血栓栓塞症(venous thromboembolism, VTE)、肺栓塞(pulmonary embolism, PE)、严重出血事件,则立即中止试验,视为研究提前终点。 |

|
Description for medicine or protocol of treatment in detail: |
1. Narheparin calcium subcutaneous injection injection was used in the hip fracture group. Patients were given LMWH once a day from admission to 12 hours before surgery, and continued to be given once a day from 12 hours after surgery to discharge. 2. Eenoxaparin sodium subcutaneous injection was used in the hip and knee replacement groups. Patients were given LMWH at 12h after surgery once a day until discharge. 3. The preventive dose of LMWH is strictly according to the drug instruction. 4. This study tried to control the differences in variables and adopted homogeneous treatment and management. 5. The surgery time was arranged according to the group of patients, so that each patient was injected with LMWH within 12-24 hours after operation. 6. Hospital discharge was the normal end point of the study. If DVT, venous thromboembolism (VTE), pulmonary embolism (PE), or severe bleeding events occur, the trial will immediately stop and consider as an early endpoint of the study. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰地载入病例报告表,录入采用相应的数据库系统双人双机录入,之后对数据库进行两遍比对。电子数据文件分类保存,并有多个备份保存于不同磁盘或者记录介质上,妥善保存,防止损坏。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Based on the original observation records, researchers will completely write accurate data into case report forms in time. Input the data into corresponding database system by two special researchers with two computers respectively. After that, researchers compare two database twice and electronic data will be conserved and backup. |
