干预措施:

Interventions:

组别:

利多卡因组

样本量:

93

Group:

Lidocaine Group

Sample size:

干预措施:

利多卡因组患者在麻醉诱导前静脉推注2%利多卡因(1.5mg/kg),2分钟后静脉推注舒芬太尼(0.2μg/kg)和丙泊酚(2mg/kg),直至患者BIS<85。术中持续监测BIS维持目标70-85,若BIS>85或病人出现不自主体动,按0.5mg/kg追加丙泊酚。

干预措施代码:

Intervention:

In the lidocaine group, 2% lidocaine (1.5mg/kg) was intravenously injected before anesthesia induction. Two minutes later, sufentanil (0.2μg/kg) and propofol (2mg/kg) were intravenously injected until the patient's BIS was less than 85. During the operation, BIS was continuously monitored to maintain the target range of 70-85. If BIS was greater than 85 or the patient showed involuntary movements, an additional 0.5mg/kg of propofol was administered.

Intervention code:

组别:

生理盐水组

样本量:

93

Group:

Saline Group

Sample size:

干预措施:

生理盐水组患者接受麻醉诱导前0.9% 生理盐水(0.075ml/kg),2分钟后静脉推注舒芬太尼(0.2μg/kg)和丙泊酚(2mg/kg),直至患者BIS<85。术中持续监测BIS维持目标70-85,若BIS>85或病人出现不自主体动,按0.5mg/kg追加丙泊酚。

干预措施代码:

Intervention:

Patients in the normal saline group received 0.9% normal saline (0.075 ml/kg) before anesthesia induction. Two minutes later, sufentanil (0.2 μg/kg) and propofol (2 mg/kg) were intravenously injected until the patient's BIS was less than 85. During the operation, BIS was continuously monitored to maintain the target range of 70-85. If BIS was greater than 85 or the patient showed involuntary movements, an additional 0.5 mg/kg of propofol was administered.

随机方法(请说明由何人用什么方法产生随机序列):

随机序列生成:由西安交通大学流行病与卫生统计学教研室使用SPSS软件生成随机数,奇数对应利多卡因组,偶数对应生理盐水组。该过程由统计专家独立完成,未参与麻醉操作及数据收集。

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

Random sequence generation: The Department of Epidemiology and Health Statistics of Xi 'an Jiaotong University used SPSS software to generate random numbers. Odd numbers corresponded to the lidocaine group, and even numbers corresponded to the normal saline group. This process was independently completed by statistical experts, who did not participate in the anesthesia operation or data collection.

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:

患者事先不知自己分组情况,知情同意签署时明确告知随机分在任一组的可能性。 盲法制备:第三方不参与研究人员制备外观一致的试验药(如利多卡因)与对照药(如生理盐水),统一用编码(如 R001)标注,隐藏药物成分信息。 盲态操作:患者入组后,研究者按顺序领取编码药物实施干预,全程不知晓药物成分;结局评估由独立观察员完成,仅记录患者编号,不接触分组信息。

Blinding:

Patients were unaware of their groupings in advance. When signing the informed consent, they were clearly informed of the possibility of being randomly assigned to any group. Blind preparation: Third parties do not participate in the researchers' preparation of test drugs (such as lidocaine) and control drugs (such as normal saline) with consistent appearance. They are uniformly labeled with codes (such as R001) to hide the information of drug components. Blind operation: After the patients were enrolled, the researchers received the coded drugs in sequence for intervention, and were unaware of the drug components throughout the process. The outcome assessment was conducted by independent observers, who only recorded the patient numbers and did not have access to the grouping information.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

研究者先填写 CRF,经双人核对确保纸质记录准确无误后,再将数据录入 ResMan 系统。录入完成后,数据管理员在系统中对录入数据与 CRF 进行二次核对,发现差异及时与录入人员沟通确认并修正,确保纸质记录与电子数据一致。

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

The researchers first filled out the CRF. After being double-checked by two people to ensure the accuracy of the paper records, the data were entered into the ResMan system. After the data entry is completed, the data administrator conducts a secondary verification of the entered data against the CRF in the system. If any differences are found, they promptly communicate and confirm with the entry personnel and make corrections to ensure that the paper records are consistent with the electronic data.
