干预措施:

负荷剂量:于麻醉诱导前10分钟内,经外周静脉缓慢推注1%盐酸利多卡因注射液(5 ml:0.1 g,石药银湖制药有限公司,国药准字H14024045),剂量为1.5 mg/kg(实际给药体积根据体重计算:体重kg × 0.15 ml)。推注时间不少于2分钟。 维持剂量:负荷剂量给药结束后,立即使用微量注射泵持续静脉输注1%盐酸利多卡因,输注速率为1.5 mg/kg/h(给药速率 = 体重kg × 0.15 ml/h),直至手术结束缝皮时停药。 药物准备:由一名不参与临床评估的研究者根据随机分组结果,抽取等体积的利多卡因原液或0.9%氯化钠注射液,置于外观完全一致的20 ml无菌注射器中,并标注受试者研究代码及“负荷剂量”“维持剂量”字样。维持剂量输注液配制方法:将利多卡因原液(或生理盐水)按体重计算所需体积,用0.9%氯化钠注射液稀释至50 ml注射器中,输注速率根据体重设置为对应ml/h,以保证给药剂量准确。

干预措施代码:

Intervention:

Bolus dose: Within 10 minutes before anesthesia induction, 1% lidocaine hydrochloride injection (5 ml:0.1 g, CSPC Yinhu Pharmaceutical Co., Ltd., National Drug Approval Number H14024045) was slowly administered intravenously via peripheral line at a dose of 1.5 mg/kg (injection volume = body weight in kg × 0.15 ml). The bolus injection was given over no less than 2 minutes. Maintenance dose: Immediately after the bolus, a continuous intravenous infusion of 1% lidocaine was started using a syringe pump at a rate of 1.5 mg/kg/h (infusion rate = body weight in kg × 0.15 ml/h). The infusion was continued until the end of surgery (start of skin closure). Drug preparation: A researcher not involved in clinical assessments prepared the study drugs according to the randomization result. Equal volumes of lidocaine or 0.9% normal saline were drawn into visually identical 20 ml sterile syringes labeled with the subject’s study code and "Bolus" or "Maintenance". For the maintenance infusion, the calculated volume of lidocaine (or normal saline) was diluted with 0.9% normal saline to a total volume of 50 ml in a syringe; the infusion rate was set in ml/h based on body weight to ensure accurate dosing.

干预措施:

负荷剂量:在相同时间点静脉推注与利多卡因组等体积的0.9%氯化钠注射液。 维持剂量:以等体积、等速率的0.9%氯化钠注射液持续输注至手术结束。 外观一致性:所有试验用药(利多卡因/生理盐水)在注射器、输液管路及输注过程中外观完全一致,麻醉医师、手术团队、结局评估者及受试者均无法通过外观区分分组。

干预措施代码:

Intervention:

Bolus dose: An equal volume of 0.9% normal saline was administered intravenously at the same time point. Maintenance dose: An equal volume and rate of 0.9% normal saline was infused continuously until the end of surgery. Blinding maintenance: All study drugs were identical in appearance (syringes, infusion lines, and running infusion pumps). The anesthesiologists, surgical team, outcome assessors, and subjects were all blinded to group allocation.

随机方法(请说明由何人用什么方法产生随机序列):

由一名不参与临床评估及干预实施的研究者,使用随机数字表生成1–104的随机数字序列。每个随机数字对应一个受试者序号,并按照预先设定的规则将受试者分配至利多卡因组(L组)或生理盐水组(C组)。

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

A researcher who was not involved in clinical assessments or intervention administration generated a random number sequence from 1 to 104 using a random number table. Each random number corresponded to a subject ID, and subjects were assigned to either the lidocaine group (Group L) or the normal saline group (Group C) according to a pre-specified allocation rule.

盲法:

负责麻醉诱导与维持的麻醉医师、术中测量视神经鞘直径(ONSD)的评估者、术后随访及谵妄评估的研究者,以及受试者本人,均对分组情况不知情。整个研究期间,分组信息严格保密,直至数据分析完成后方由随机序列生成者揭盲。

Blinding:

The anesthesiologists responsible for anesthesia induction and maintenance, the outcome assessors measuring optic nerve sheath diameter (ONSD), the researchers conducting postoperative follow-up and delirium assessments, and the subjects themselves were all blinded to group allocation. The allocation information remained strictly confidential throughout the study and was only revealed by the sequence generator after the data analysis was completed.
