随机方法(请说明由何人用什么方法产生随机序列):

采用分层区组随机,以性别作为分层因素,在每个组合层内,区组长度设为4和6并按随机顺序交替使用,按1:1的比例将受试者分配至试验组和对照组,避免研究者通过固定的区组长度猜测分组。负责执行干预的麻醉医生采用基于网络的随机化系统(RandIMI插件,整合于RedCAP研究电子数据采集平台,西交公共卫生学院建立并维护)进行随机分配。

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

Randomization was performed using stratified block randomization, with sex as the stratification factor. Within each stratum, block sizes of 4 and 6 were used alternately in a random sequence to maintain allocation concealment and prevent investigators from predicting group assignment based on a fixed block size. Participants were allocated in a 1:1 ratio to either the experimental group or the control group. The randomization sequence was generated using a web‑based randomization system (the RandIMI plugin, integrated into the RedCAP electronic data capture platform, established and maintained by the School of Public Health, Xi'an Jiaotong University) by an anesthesiologist responsible for performing the intervention.

盲法:

由指定的、不参与术后随访的麻醉医师知晓分组结果并执行干预。两组使用外观完全相同的tVNS501经皮耳迷走神经刺激仪,患者本人和其他所有参与研究的研究人员(包括麻醉实施医生、手术医生、术后护理人员以及负责评估和数据分析的人员)均不知道每一位患者具体属于哪一组。防止研究人员在麻醉管理、结果评估或统计分析时因知晓分组而产生主观倾向;也能防止患者因知晓自己所接受的治疗而产生心理暗示效应。研究后期收集患者对于干预的猜想,利用邦氏盲法指数(Bang’s Blinding Index)评估对患者设盲的实施效果及盲法的成功性,BBI系数-0.2-0.2可以认为盲法设置成功。

Blinding:

The randomization assignment was known to a designated anesthesiologist who was not involved in postoperative follow‑up and who performed the intervention. Two groups used tVNS501 transcutaneous auricular vagus nerve stimulators that were identical in appearance, the patients themselves and all other study personnel (including the anesthesiologists administering anesthesia, surgeons, postoperative nursing staff, and those responsible for outcome assessment and data analysis) remained blinded to each participant’s group allocation. Unblinding was performed only after all data analyses had been completed. This design was intended to prevent investigators from introducing subjective bias during anesthesia management, outcome assessment, or statistical analysis due to knowledge of group assignment, and to avoid psychological suggestion effects in patients that might arise from awareness of the treatment they received. At the end of the study, patients’ guesses about their assigned intervention were collected. The Bang’s Blinding Index (BBI) was used to assess the effectiveness of patient blinding and the success of the blinding procedure. A BBI value between –0.2 and 0.2 was considered to indicate successful blinding.
