Description for medicine or protocol of treatment in detail: |
Group A (MR group, experimental group): After anesthesia induction, patients received ultrasound-guided bilateral transversus abdominis plane block (TAPB). Each side was injected with a sterile solution composed of 0.375% ropivacaine hydrochloride and 0.05% methylene blue, totaling 20ml (7.5ml of 1% ropivacaine hydrochloride + 1ml of 1% methylene blue + 11.5ml of 0.9% sodium chloride). The total bilateral dose was 150mg of ropivacaine and 20mg of methylene blue. Group B (R group, control group): After anesthesia induction, patients received ultrasound-guided bilateral transversus abdominis plane block (TAPB). Each side was injected with 20ml of 0.375% ropivacaine hydrochloride (7.5ml of 1% ropivacaine hydrochloride + 12.5ml of 0.9% sodium chloride). The total bilateral dose was 150mg of ropivacaine. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用区组随机化方法,由独立统计学家使用统计软件(如SAS或R)生成随机分配序列。设置区组大小为4或6,以确保两组在招募过程中人数基本平衡。随机化将按年龄(≤60岁 vs >60岁)? 进行分层,以控制年龄对疼痛感知和免疫功能可能的影响 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study employed a block randomization method, with an independent statistician generating the random allocation sequence using statistical software (such as SAS or R). The block size was set at 4 or 6 to ensure a roughly balanced number of participants in both groups during recruitment. Randomization was stratified by age (≤60 years vs >60 years) to control for potential effects of age on pain perception and immune function. |

盲法: |
设盲对象:受试者:被告知将接受“一种用于术后镇痛的神经阻滞”,但不被告知具体药物组成。两组注射液外观(均为淡蓝色,因亚甲蓝本身为蓝色,MR组颜色略深,但可通过使用避光注射器或包装使外观一致化,若难以完全一致,需在方案中说明并评估其对盲法的影响)将尽可能保持一致。 结局评估者:负责术后VAS评分询问、随访记录、不良事件收集的研究护士或数据管理员对分组信息不知情。 数据统计人员:在数据分析阶段对分组采用盲态编码(如A组/B组)。 未设盲对象:实施TAPB操作的麻醉医生、负责配制研究用药的药师知晓分组 |
|
Blinding: |
Blinding subjects: Participants: Informed that they will receive "a nerve block for postoperative analgesia," but not informed of the specific drug composition. The appearance of the injections in both groups (both light blue; since methylene blue itself is blue, the MR group has a slightly darker color, but the appearance can be standardized by using light-protected syringes or packaging. If complete consistency is unachievable, this should be stated in the protocol, and its impact on blinding should be evaluated) will be kept as consistent as possible. Outcome assessors: Research nurses or data managers responsible for postoperative VAS score inquiries, follow-up records, and adverse event collection are unaware of group assignments. Data statisticians: Use blinded coding (e.g., Group A/Group B) for group assignments during data analysis. Non-blinded subjects: The anesthesiologist performing the TAPB procedure and the pharmacist preparing the study drugs are aware of group assignments. |
