干预措施:

Interventions:

组别:

主动taVNS组

样本量:

63

Group:

The Active transcutaneous Auricular Vagus Nerve Stimulation (taVNS) Group

Sample size:

干预措施:

依据随机分组结果放置电极于左耳甲区并调整刺激参数脉冲宽度200 μs,频率20 Hz,电流30秒内逐渐升至患者感觉明显刺痛阈值后下调至略低于阈值并维持;刺激自麻醉诱导后开始,贯穿手术过程,于PACU拔管后停止并移除设备。研究人员全程观察,出现不能耐受的不良反应立即停止刺激。

干预措施代码:

Intervention:

Based on random grouping results, electrodes were placed on the left ear concha region, and stimulation parameters were adjusted as follows: pulse width 200 μs, frequency 20 Hz; the current was gradually increased within 30 seconds until the patient felt an obvious tingling pain threshold, then decreased to a level slightly below the threshold and maintained. Stimulation was initiated after anesthesia induction, continued throughout the entire surgical procedure, and was terminated with the equipment removed after extubation in the Post-Anesthesia Care Unit (PACU). The research personnel conducted continuous monitoring throughout the process, and stimulation was immediately terminated if intolerable adverse reactions occurred.

Intervention code:

组别:

假刺激组

样本量:

63

Group:

Sham Stimulation Group

Sample size:

干预措施:

电极放置同主动组;电流同样在30秒内升至刺痛阈值后下调至略低阈值,随后设备保持关闭以模拟假刺激。移除设备时间同主动组一致。

干预措施代码:

Intervention:

Electrode placement is identical to that in the active group; the current is also increased to the pain threshold within 30 seconds, then adjusted down to a slightly lower threshold, after which the device is kept switched off to simulate sham stimulation. The timing of device removal is consistent with that of the active group.
