研究目的:

通过应用超声造影剂,提高超声的分辨力、敏感性和特异性;同时应用六氟化硫微泡超声造影,收集患者移植肾血流障碍及急性排斥反应的不同表现,为临床诊断提供依据。  

Objectives of Study:

To improve the resolution, sensitivity and specificity of ultrasound by applying ultrasound contrast agents. In the meantime, to collect the different manifestations of renal allograft blood flow disorders and acute rejection in recipients of kidney transplants with the application of sulphur hexafluoride microbubbles, in order to provide a favorable basis for clinical diagnosis.

药物成份或治疗方案详述:

药物成分 六氟化硫微泡(声诺维)组成为白色冻干粉末,上充六氟化硫气体;冻干粉末辅料组成:聚乙二醇4000,二硬脂磷酯酰胆碱(DSPC),二棕榈磷酯酰甘油(DPPG.Na),棕榈酸。 治疗方案 经皮肤消毒肘前静脉建立静脉通道,注入超声造影剂声诺维,然后注入生理盐水,同时实时超声显像。一名超声医师及一名护士即可完成操作。静脉注射较为安全。 

Description for medicine or protocol of treatment in detail:

Drug ingredients: The composition of sulphur hexafluoride microbubbles (SonoVue) is white freeze-dried powder, filled with sulphur hexafluoride gas. The composition of freeze-dried powder excipients: PEG-4000, distearyl phosphatidylcholine (DSPC), Dipalmitophosphate acylglycerol (DPPG.Na), palmitic acid(PA). Treatment plan: After the skin disinfection, to establish a venous channel by the anterior elbow vein. Inject the ultrasound contrast agent(SonoVue), and then inject normal saline, do the real-time ultrasound imaging in the same time. A sonographer and a nurse can complete this operation. Intravenous injection is safer compared to other ways.

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:

在收集数据之前,我们将根据需要为每个对象建立CRF。本研究中的所有临床资料应客观记录在CRF上。研究完成后,我们将任命两名技术人员分别将数据输入数据库。如果输入的数据不一致,将由第三名技术人员来纠正错误。一旦受试者被纳入,研究单位将尽一切合理的努力来随访整个研究期间的受试者。预计总计的失访率将至多为20%。研究单位的工作人员有责任实施标准操作流程,以完成该研究的随访。所有与研究相关的资料,将被保存在保险柜中。访问研究数据将受到限制。由于本研究规模较小,未建立电子采集和管理系统。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Before collecting data, we will establish CRF for each subject as needed. All clinical data in this study should be objectively recorded on the CRF. After the research is completed, we will appoint two technicians to enter the data into the database. If the entered data is inconsistent between these two technicians, a third technician will correct the error. Once the subjects are included in this research, the research unit will make all reasonable efforts to follow up the subjects throughout the study period. The total loss to follow-up rate is expected to be at most 20%. The staffs of the research unit are responsible for implementing standard operating procedures to complete the follow-up of the research. All data related to the research will be kept in the safe. Access to research data will be restricted. Due to the small scale of this research, there is no Electronic Data Capture System to be established in the research.
