随机方法(请说明由何人用什么方法产生随机序列):

我们将採用分层随机化方法,以确保不同类型麻醉的治疗臂之间的平衡,这是一个重要的效果调整因素。参与者最初将根据他们所接受的麻醉类型进行分层: 全身麻醉 (GA) 或局部麻醉 (LA)。在每个麻醉组别中,参与者将进一步随机分配接受局部氨甲环酸 (TXA) 或对照治疗。 由于预期接受全身麻醉和局部麻醉的参与者人数可能不相等,因此我们的目标是在随机分层之前,确保每个组别都有适当的平衡。参与者将根据麻醉类型分为两个分层。第一层包括预定接受 GA 的参加者,第二层包括预定接受 LA 的参加者。 在每个分层中,我们将採用区块随机化以维持平衡并防止选择偏差。在可能的情况下,区块大小将设定为四个,每个区块包含两名分配至 TXA 组和两名分配至对照组的参与者。但是,如果分层中的总参加者人数不是四的倍数,则会使用较小的区块大小(例如两个)来容纳剩馀的参加者。此方法可确保在每个区块结束后,各治疗组之间的分配仍保持平衡。每个区块内的随机化将使用电脑产生的随机化顺序进行,以确保分配的隐蔽性和公正性。

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

We will employ a stratified randomization method to ensure balance between the treatment arms across different types of anesthesia, which is an important effect modifier. Participants will be initially stratified based on the type of anesthesia they will receive: General Anesthesia (GA) or Local Anesthesia (LA). Within each anesthesia group, participants will then be further randomized to receive either topical Tranexamic Acid (TXA) or a control treatment. Anticipating that the number of participants receiving General Anesthesia and Local Anesthesia may not be equal, we aim for the stratification to ensure that each group is appropriately balanced before randomization. Participants will be divided into two strata based on the type of anesthesia. The first stratum will include participants scheduled to receive GA, and the second stratum will include those scheduled to receive LA. Within each stratum, we will utilize block randomization to maintain balance and prevent selection bias. The block size will be set at four, where possible, with each block containing two participants assigned to the TXA group and two to the control group. However, if the total number of participants within a stratum is not a multiple of four, smaller block sizes (such as two) will be used to accommodate the remaining participants. This method ensures that after every block, the allocation remains balanced between the treatment groups. Randomization within each block will be performed using a computer-generated randomization sequence, ensuring the allocation is concealed and unbiased.

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

在 GA 组中,参与者将以四个区块随机排列,每个治疗组有 34 名参与者。由于参加者人数不能被四整除,因此馀下的参加者将使用较小的区块。 在 LA 组中,参加者同样以四人为一组进行随机分配,结果每个治疗组有 34 名参加者。馀下的参与者将视需要使用较小的区块进行分配。

Blinding:

In the GA group, participants will be randomized in blocks of four, resulting in 34 participants in each treatment arm. The number of participants is not divisible by four, hence, smaller blocks will be used for the remaining participants. In the LA group, participants will similarly be randomized in blocks of four, resulting in 34 participants in each treatment arm. Any remaining participants will be assigned using smaller blocks as necessary.

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:

我們將非常謹慎地處理患者數據,以確保不會以任何形式侵犯患者的隱私。資料將儲存在需要密碼操作的安全櫃和/或電腦中。為保障病人私隱,所有研究資料均會依照醫管局/醫院處理/儲存/銷毀病人醫療紀錄的政策處理。電子資料將保存在醫院的安全電腦中,並受到限制存取。 USB 裝置不會用於儲存病患資訊或個人資料。個人資料(姓名、香港身分證、門診/醫院號碼、地址及任何其他可識別個人身分的資料)不會記錄於項目的資料表或電子檔案。應使用學習代碼來代替。包含研究代碼與患者身份之間的關聯信息的電子文件文檔不會包含任何其他信息,並且將與研究數據文件或數據表分開保存,並具有與醫療記錄同樣嚴格的安全性。任何包含個人識別資訊的文件或電子文件都將被視為醫療記錄的一部分,並將根據醫院政策受到同樣嚴格的安全規定處理。所有研究人員都將負責資料處理和保護。

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

Patient data would be handled with utmost care taking care not to breach patient's privacy in any form. The data would be stored in secure cabinets and/or computers which would be password operated. To protect patient privacy, all research data would be handled in line with HA / Hospital’s policy in handling / storage / destruction of patients’ medical records. Electronic data would be saved in secured computer of the hospital with restricted access. USB Device would not be used for patient information nor personal data. Personal data (name, HKID, OPD / hospital numbers, address and any other personal identifiable information) would not be recorded on the project’s data sheets or electronic files. A study code would be used instead. The document of electronic file containing the linkage information between the study code and the identity of the patient would not contain any other information and would be kept separate from the study data files or data sheets with the same stringent security as the medical record. Any documents or electronic files containing personal identifiable information would be considered as part of the medical record and would be dealt with the same stringent regulations of security according to the hospital policies. All the investigators would be responsible for data handling and protection.
