研究目的: |
椎管内麻醉因其区域阻滞效果确切、对呼吸循环干扰小,广泛用于下腹部及下肢手术。然而,术中患者常处于清醒或轻度镇静状态,易受手术环境、声光刺激及病情担忧等多重应激源影响,引发心理与生理应激反应。此类应激不仅降低患者舒适度与满意度,还可引起血流动力学波动,增加围术期心血管风险,并与术后疼痛加剧、康复延迟及住院时间延长等不良结局相关。 为缓解术中焦虑,辅助镇静作为关键干预方式已广泛应用于临床,理想的辅助镇静应在有效缓解焦虑的同时,尽量避免过度抑制患者生理功能。丙泊酚作为一种起效迅速、苏醒彻底、不易蓄积的短效静脉麻醉药,联合靶控输注(TCI)技术可实现镇静深度精确调控,满足辅助镇静需求。除镇静作用外,丙泊酚还可诱发欣快感——一种以愉悦、放松和幸福感为特征的积极情感状态,该特性有助于针对性缓解术中恐惧,进一步提升整体医疗体验。 欣快感不仅可即时减轻焦虑水平,还可长期强化其对医疗过程的积极记忆,甚至优化对手术结局的主观评价。然而其伴随一定药物非医疗使用风险。因此,建立客观、可靠的欣快感评估工具,对平衡其临床收益与潜在风险至关重要。 脑电图(EEG)作为监测丙泊酚脑功能状态的有效工具,已证实可捕捉其诱导的结构化振荡模式转变。鉴于欣快感为一独立神经心理状态,本研究提出其可能具备EEG生物标志物。本研究拟通过EEG分析,探索丙泊酚维持不同镇静深度诱发欣快状态的神经电生理标志物,旨在为丙泊酚的临床合理应用与风险管理提供客观依据。 本研究拟招募椎管内麻醉下接受下肢手术、美国麻醉医师协会(ASA)分级为 I–III 级的患者。术前在获得伦理委员会批准并取得患者书面知情同意后,将记录并评估其一般资料、焦虑、抑郁及睡眠状况,采集基线EEG,术中采用Narcotrend脑电监测系统持续评估镇静深度,并采集平稳状态的EEG。于术前及术后30分钟采用情绪成瘾研究中心量表(ARCI-MBG)、视觉模拟评分(VAS)、正性负性情绪量表 (PANAS)评估术中欣快状态,于术后1周及术后1月使用ARCI-MBG量表回访评估欣快的记忆持续情况。本研究拟通过一项随机对照试验,系统探讨不同丙泊酚镇静深度下欣快感发生率的差异,并致力于发现与之相关的EEG客观标志物,为临床精准化、人性化镇静策略提供理论与实证依据。 |

Objectives of Study: |
Epidural anesthesia is widely used for lower abdominal and lower extremity surgeries due to its reliable regional blockade and minimal disturbance to respiratory and circulatory functions. However, during surgery, patients are often awake or under mild sedation, making them susceptible to various stressors such as the surgical environment, audiovisual stimuli, and concerns about their condition, which can trigger psychological and physiological stress responses. This stress not only reduces patient comfort and satisfaction but can also lead to hemodynamic fluctuations, increase perioperative cardiovascular risk, and is associated with adverse outcomes like intensified postoperative pain, delayed recovery, and prolonged hospital stay. To alleviate intraoperative anxiety, adjunct sedation, as a key intervention, has been widely adopted in clinical practice. The ideal adjunct sedation should effectively relieve anxiety while minimizing excessive suppression of the patient's physiological functions. Propofol, a short-acting intravenous anesthetic with rapid onset, clear emergence, and low accumulation, combined with Target-Controlled Infusion (TCI) technology, allows for precise regulation of sedation depth, meeting the requirements for adjunct sedation. Beyond its sedative effect, propofol can also induce euphoria—a positive affective state characterized by pleasure, relaxation, and a sense of well-being. This property can help specifically alleviate intraoperative fear and further enhance the overall medical experience. Euphoria can not only immediately reduce anxiety levels but may also strengthen positive memories of the medical procedure in the long term and even improve subjective evaluation of surgical outcomes. However, it carries a certain risk of non-medical use of the drug. Therefore, establishing objective and reliable tools for assessing euphoria is crucial for balancing its clinical benefits and potential risks. Electroencephalography (EEG), as an effective tool for monitoring propofol-induced cerebral functional states, has been proven capable of capturing its induced transitions in structured oscillatory patterns. Given that euphoria is an independent neuropsychological state, this study proposes that it may possess specific EEG biomarkers. This study aims to explore the neuroelectrophysiological biomarkers of euphoric states induced by propofol maintained at different sedation depths through EEG analysis, intending to provide an objective basis for the rational clinical application and risk management of propofol. This study plans to recruit patients undergoing lower extremity surgery under epidural anesthesia, classified as American Society of Anesthesiologists (ASA) physical status I–III. After obtaining approval from the Ethics Committee and written informed consent from the patients preoperatively, their general information, anxiety, depression, and sleep status will be recorded and assessed, and baseline EEG will be collected. During surgery, the Narcotrend EEG monitoring system will be used to continuously assess sedation depth, and EEG during stable states will be acquired. Intraoperative euphoric state will be assessed preoperatively and 30 minutes postoperatively using the Addiction Research Center Inventory Morphine-Benzedrine Group Scale (ARCI-MBG), Visual Analog Scale (VAS), and Positive and Negative Affect Schedule (PANAS). Follow-up assessments of the persistence of euphoric memory will be conducted at 1 week and 1 month postoperatively using the ARCI-MBG scale. Through a randomized controlled trial, this study aims to systematically investigate the differences in the incidence of euphoria under different propofol sedation depths and is committed to discovering objective EEG biomarkers associated with it, providing theoretical and empirical evidence for clinical precision and humanized sedation strategies. |
