研究目的:

肝脏移植是解决终末期肝病的唯一方法,目前手术技巧已经成熟,然而术后早期器官损伤并发症高,特别是围术期发生的急性呼吸窘迫综合征(ARDS)发生率高达38%,严重限制了术后患者的早期康复,目前尚无有效的药物治疗手段。本项目拟开发肝移植围术期ARDS临床药物治疗方案,拟通过在肝移植患者术中吸入NO方式,比较NO吸入与空气吸入两种患者ARDS发生率,探讨NO吸入对肝移植围术期ARDS的防治作用。  

Objectives of Study:

Liver transplantation is the only way to solve end-stage liver disease. At present, the surgical technique has matured. However, the complications of early postoperative organ injury are high, especially the incidence of acute respiratory distress syndrome (ARDS) occurring in the perioperative period is as high as 38%, which seriously limits the early recovery of postoperative patients. At present, there is no effective drug treatment. This project plans to develop a clinical drug treatment plan for ARDS during the perioperative period of liver transplantation. It plans to compare the incidence of ARDS in patients with NO inhalation and air inhalation through the way of inhaled NO during liver transplantation, and explore the prevention and treatment effect of NO inhalation on ARDS during the perioperative period of liver transplantation.

药物成份或治疗方案详述:

内源性NO一种由血管内皮细胞产生的内源性介质,是一种强大的血管扩张剂,因其可改善通气血流匹配和氧合,常作为选择性肺血管扩张剂使用。NO是由内皮一氧化氮合酶(eNOS)将L-精氨酸氧化为L-瓜氨酸产生的。NO扩散到平滑肌细胞等靶细胞中,结合和激活可溶性鸟苷酸环化酶(sGC),而鸟苷酸环化酶反过来又从GTP产生cGMP,以促进血管扩张,并抑制细胞迁移和增殖。 

Description for medicine or protocol of treatment in detail:

Endogenous NO, an endogenous medium produced by vascular endothelial cells, is a powerful vasodilator. It is often used as a selective pulmonary vasodilator because it can improve ventilation and blood flow matching and oxygenation. NO is produced by the oxidation of L-arginine to L-citrulline by endothelial nitric oxide synthase (eNOS). NO diffuses into target cells such as smooth muscle cells and binds and activates soluble guanylate cyclase (sGC), which in turn generates cGMP from GTP to promote vascular expansion and inhibit cell migration and proliferation.

随机方法(请说明由何人用什么方法产生随机序列):

采用中央随机系统进行随机化分组,采用完全简单随机方法将患者随机分为两组,通过中央随机系统得到麻醉编号后进行分组。根据临床试验随机化方案对试验干预方法进行计算机随机编码,试验干预方法随机编码为受试者唯一识别码。根据受试者手术的顺序,随机分为干预组和对照组。符合纳排标准的患者住院手术准备,由负责统计分析的临床医生录入患者信息,系统自动分配随机编码和分组编码。

Randomization Procedure (please state who generates the random number sequence and by what method):

Randomized grouping was carried out using the central randomization system. Patients were randomly divided into two groups using a completely simple randomization method. The anesthesia number was obtained through the central randomization system and then grouped. According to the clinical trial randomization scheme, the t

盲法:

本临床试验选择双盲。在研究期间,入选受试者,负责麻醉管理的医师,临床数据采集专员,麻醉复苏室护士,随访人员,病房护士,统计分析人员均对分组不知情。研究助理(2 人)仅负责分组和分配输注药物,是唯一对研究分组知情的人员,但是他们不参与研究任何阶段的工作。患者入手术室后,研究助理根据随机化系统得出的分组情况进行分配吸入一氧化氮或者空气(安慰剂),数据收集完毕后由专业统计分析人员完成最后的数据分析。

Blinding:

This clinical trial is double-blind. During the study period, the selected subjects, doctors in charge of anesthesia management, clinical data collection specialists, nurses in anesthesia resuscitation room, follow-up staff, ward nurses, and statistical analysts were all unaware of the grouping. The research assistant (2 persons) is only responsible for grouping and distributing infusion drugs, and is the only person who knows about the research group, but they do not participate in the work at any stage of the study. After the patient enters the operating room, the research assistant will distribute inhaled nitric oxide or air (placebo) according to the grouping conditions obtained by the randomization system. After the data collection, professional statistical analysts will complete the final data analysis.
