研究目的:

本试验的主要目的是确定使用阿司匹林肠溶片抗血小板治疗(相对于不使用抗血小板药物治疗)对经过单纯栓塞或夹闭处理的aSAH患者的有效性(更好的功能结果而不是影像学结果)。此外,我们的目标是确定中度或重度SAH患者的某些亚组是否会有更大的治疗获益,以及确定抗血小板治疗是否会减少此类患者的DCI发生率。最后,我们将评估早期的抗血小板治疗对此类患者是否安全。  

Objectives of Study:

The main objective of this trial is to determine the efficacy of using aspirin enteric-coated tablets for antiplatelet therapy (compared to no antiplatelet drug therapy) in patients with aSAH who have undergone simple embolization or clipping (better functional outcomes rather than imaging results). Additionally, our goal is to determine whether certain subgroups of patients with moderate or severe aSAH will have greater treatment benefits, and to determine whether antiplatelet therapy will reduce the incidence of DCI in such patients. Finally, we will evaluate the safety of early antiplatelet therapy in such patients.

根据阿司匹林肠溶片药物特性,我们将通过口服或肛门给药将是试验的试验干预。对于清醒、未禁食并可进行口服药物的患者,我们将通过口服药物的方式在患者进食前至少30分钟给患者服药,且不应压碎、掰开或咀嚼肠溶片,以确保活性物质在小肠碱性环境中释放。对于昏迷或禁食病人我们将采用肛门给要得方式,安慰剂药片给予相同方式处理,给药剂量为100mg,连续给药21天。

干预措施代码:

Intervention:

According to the pharmacological properties of aspirin enteric-coated tablets, oral or rectal administration will be the experimental intervention in this trial. For conscious patients who have not fasted and can take oral medications, we will administer the drug orally at least 30 minutes before meals. The enteric-coated tablets should not be crushed, broken, or chewed to ensure the release of the active substance in the alkaline environment of the small intestine. For comatose patients or those on fasting, we will use rectal administration. Placebo tablets will be handled in the same way. The dosage is 100 mg, and the administration will be continued for 21 days.

随机方法(请说明由何人用什么方法产生随机序列):

对于符合所有临床和影像学纳入标准的患者,立即由XXX使用计算机和网络软件采用最小随机化方法将其随机分组。患者将被分配(1∶1随机化)至阿司匹林组或安慰剂对照组。随机化结果对治疗医师和患者均保密。治疗医师只被告知随机分组的病例编号。

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

For patients who meet all the clinical and imaging inclusion criteria, XXX will immediately use a computer and network software to randomly assign them to groups using the minimization randomization method. Patients will be assigned (1:1 randomization) to the aspirin group or the placebo control group. The randomization results will be kept confidential from both the treating physicians and the patients. The treating physicians will only be informed of the case numbers of the randomized groups.

盲法:

本试验将采用双盲设计,治疗药物与安慰剂在外观上相同。一旦从符合所有入选标准的患者或家属获得同意书,将通过使用计算机和网络软件招启动随机化过程。患者将被分配到阿司匹林治疗组或安慰剂组(1:1随机)。随机化结果连同病例编号或随机化编号将被发送给预先指定的药剂师。将只通知治疗医师患者入组随机化编号,而不通知随机化结果。 由于双盲设计,单盲试验中常见的交叉有可能避免,但退出是可能和被允许的。在试验结束前,不向退出患者透露任何治疗信息。预定的评估不需要第三方,将由治疗医师作为标准治疗的一部分进行。 为了保证盲法的实现,用于测试的阿司匹林肠溶片和安慰剂药片将按照指定的工艺生产,以确保其外观无法从视觉上区分。在试验开始前,所有试验药物(包括药物和安慰剂)将统一包装和标签。不包含分组信息的标识符确保在试验期间保持双盲。在整个试验期间,研究人员和患者将无法知道干预的信息。只有包装的药剂师或经销商了解药物治疗信息。

Blinding:

This trial will adopt a double-blind design, and the treatment drug and placebo will be identical in appearance. Once informed consent forms are obtained from patients or their families who meet all the inclusion criteria, the randomization process will be initiated using a computer and network software. Patients will be assigned to either the aspirin treatment group or the placebo group (randomized 1:1). The randomization results, along with the case number or randomization number, will be sent to a pre-designated pharmacist. The treating physician will only be informed of the patient's randomized enrollment number, not the randomization result. Due to the double-blind design, the crossover commonly seen in single-blind trials can be avoided, but withdrawals are possible and permitted. No treatment information will be disclosed to patients who withdraw before the end of the trial. The scheduled evaluations do not require a third party and will be conducted by the treating physician as part of standard care. To ensure the implementation of the blinding method, the enteric-coated aspirin tablets and placebo tablets used in the test will be produced according to the specified process to ensure that their appearance cannot be visually distinguished. Before the start of the trial, all trial drugs (including the active drug and placebo) will be uniformly packaged and labeled. Identifiers that do not contain group information ensure that the double-blind state is maintained during the trial. Throughout the trial, neither the researchers nor the patients will know the information about the intervention. Only the packaging pharmacist or distributor will have knowledge of the drug treatment information.
