研究目的:

主要目的是比较术前超声引导下星状神经节阻滞与假阻滞对术后 3 天内谵妄累积发生率的影响。次要目的是评估星状神经节阻滞对谵妄严重程度和持续时间、术后恢复情况(恢复质量 - 15 评分)、炎症生物标志物(降钙素原、C 反应蛋白、白细胞介素 - 6、全身免疫炎症指数 [SII]、淋巴细胞与单核细胞比值 [LMR]、中性粒细胞与淋巴细胞比值 [NLR])、疼痛轨迹、阿片类药物消耗量及住院时间的影响。  

Objectives of Study:

The primary objective of this study is to compare the cumulative incidence of delirium within the first 3 postoperative days between preoperative ultrasound-guided stellate ganglion block and a sham block. Secondary objectives include assessing the impact of SGB on the severity and duration of delirium, postoperative recovery (Quality of Recovery-15 score), inflammatory biomarkers (procalcitonin, C-reactive protein, interleukin-6, systemic immune-inflammation index [SII], lymphocyte-to-monocyte ratio [LMR], neutrophil-to-lymphocyte ratio [NLR]), pain trajectory, opioid consumption, and length of hospital stay. If proven effective, stellate ganglion block could serve as a feasible targeted intervention to be integrated into the perioperative care pathway for high-risk elderly patients undergoing oncological surgery.

药物成份或治疗方案详述:

1.标准化麻醉方案:麻醉诱导、维持和苏醒均按照统一方案进行管理。1. 术前管理:严格遵守禁食指南(固体食物禁食8小时,清流质禁食2小时),避免使用苯二氮?类药物进行术前用药;2. 诱导:建立标准监测后,静脉注射舒芬太尼(0.3-0.5μg/kg)、环泊酚(0.4-0.5mg/kg)和顺式阿曲库铵(0.15-0.2mg/kg)诱导麻醉。肌肉充分松弛后进行气管插管;3. 维持:采用七氟醚(呼气末浓度1.0-1.3最低肺泡有效浓度[MAC],经年龄校正)和持续输注瑞芬太尼(0.05-0.20μg/kg/min)维持麻醉。若血压或心率较基线升高>20%,则追加舒芬太尼(5-10μg)。根据需要间断给予顺式阿曲库铵维持肌肉松弛。控制通气使呼气末二氧化碳维持在35-45mmHg;4. 血流动力学管理:平均动脉压(MAP)维持在基线值的±20%范围内。若MAP降低>20%,首选静脉注射麻黄碱(6mg推注)治疗;若MAP升高>20%,则通过加深麻醉(增加七氟醚浓度或追加舒芬太尼)处理;5. 苏醒:预计手术结束前约30分钟,静脉注射酮咯酸氨丁三醇(30mg),并停止瑞芬太尼输注。达到标准拔管标准(意识清醒、自主呼吸充分、室内空气下脉搏血氧饱和度[SpO?]>95%)后进行拔管。 2. 标准化术后镇痛:拔管后,所有患者均连接标准化静脉自控镇痛(PCIA)泵。PCIA溶液含氢吗啡酮(0.15-0.2mg/kg)、纳布啡(1.0-1.5mg/kg)和昂丹司琼(16mg),用生理盐水稀释至100mL。泵设置为持续输注速率1.0mL/h,单次按压剂量2.0mL,锁定时间15分钟,1小时限量8.0mL。若PCIA镇痛效果不佳(数字评分量表[NRS]评分≥4),急性疼痛服务团队将提供补救镇痛(静脉注射氢吗啡酮0.2-0.4mg)。 

Description for medicine or protocol of treatment in detail:

1. Standardized anesthesia protocol: Anesthesia was managed according to a uniform protocol for induction, maintenance, and emergence. 1) Preoperative management:Adherence to strict fasting guidelines (8 hours for solids, 2 hours for clear liquids). Premedication with benzodiazepines was avoided. 2) Induction:Following standard monitoring establishment, anesthesia was induced with intravenous sufentanil (0.3-0.5 μg/kg), ciprofol (0.4-0.5 mg/kg), and cisatracurium (0.15-0.2 mg/kg). Tracheal intubation was performed after adequate muscle relaxation.3) Maintenance:Anesthesia was maintained with sevoflurane (end-tidal concentration 1.0-1.3 MAC, age-adjusted) and a continuous remifentanil infusion (0.05-0.20 μg/kg/min). Supplemental boluses of sufentanil (5-10 μg) were administered if blood pressure or heart rate increased by >20% from baseline. Muscle relaxation was maintained with intermittent cisatracurium as needed. Ventilation was controlled to maintain end-tidal carbon dioxide between 35-45 mmHg.4) Hemodynamic management:Mean arterial pressure (MAP) was maintained within ±20% of baseline. A decrease in MAP >20% was primarily treated with intravenous ephedrine (6 mg bolus). An increase in MAP >20% was managed by deepening anesthesia (increasing sevoflurane concentration or administering supplemental sufentanil).5) Emergence:Approximately 30 minutes before the anticipated end of surgery, ketorolac tromethamine (30 mg IV) was administered, and the remifentanil infusion was discontinued. Extubation was performed upon meeting standard criteria (consciousness, adequate spontaneous respiration, SpO? >95% on room air). 2.Standardized postoperative analgesia:After extubation, all patients were connected to a standardized patient-controlled intravenous analgesia (PCIA) pump. The PCIA solution contained hydromorphone (0.15-0.2 mg/kg), nalbuphine (1.0-1.5 mg/kg), and ondansetron (16 mg), diluted to 100 mL with normal saline. The pump was set to a basal infusion of 1.0 mL/h, a bolus dose of 2.0 mL, a lockout interval of 15 minutes, and a 1-hour limit of 8.0 mL. Rescue analgesia (hydromorphone 0.2-0.4 mg IV) was provided by the acute pain service team if pain was inadequately controlled (NRS ≥4) by the PCIA.

干预措施:

星状神经节阻滞组:该组患者将接受两次星状神经节阻滞:第一次阻滞在术前一天下午进行;第二次在手术当日麻醉诱导前30分钟进行。在无菌条件和实时超声引导下(C6水平),将22号针头推进至椎前筋膜。负压回抽无血后,注射3-5mL 0.375%罗哌卡因(图2)。阻滞后15分钟内出现霍纳综合征(眼睑下垂、瞳孔缩小、无汗症)和/或同侧皮肤温度升高>=1.5℃,则确认阻滞成功。

干预措施代码:

Intervention:

Stellate Ganglion Block Group: Patients in this group will undergo two stellate ganglion block procedures: The first block will be performed the afternoon before the surgery; the second will be administered 30 minutes before anesthesia induction on the day of the surgery. Under sterile conditions and real-time ultrasound guidance (at the C6 level), a 22-gauge needle will be advanced into the prevertebral fascia. After negative pressure aspiration without blood, 3-5 mL of 0.375% ropivacaine will be injected. Within 15 minutes after the block, if Horner's syndrome (drooping eyelid, constricted pupil, anhidrosis) and/or an increase in skin temperature on the same side of at least 1.5°C is observed, the block is confirmed to be successful.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

本研究采用双盲设计。参与者、外科医生、术后护理团队和结局评估者均不知晓分组情况。由于成功阻滞后可能出现的体征(如霍纳综合征),执行阻滞操作的麻醉医师无法设盲,但该医师不参与术后评估或数据收集。

Blinding:

This study is double-blind. Participants, surgeons, postoperative care teams, and outcome assessors will be unaware of group allocation. The anesthesiologist performing the block will not be blinded due to the potential physical signs of a successful block (e.g., Horner's syndrome) but will have no role in postoperative assessments or data collection.

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

All study data will be collected and managed using the ResMan electronic data capture platform (http://www.medresman.org.cn). Data entry will undergo double verification. Participants will be assigned a unique study identifier (UID); all stored data will be pseudonymized. Access to the final dataset will be restricted to the principal investigator and statistician. An independent data safety and monitoring board (DSMB) will review accumulating safety data and overall trial conduct at pre-specified intervals. All AEs and serious adverse events (SAEs) will be reported to the DSMB and institutional ethics committee within 24 hours of awareness. In the unlikely event of trial-related harm, participants will receive appropriate medical care at the study center.
