干预措施:

术中我们综合患者状态指数(patient state index, PSI),95%谱缘频率(95% spectral edge frequency, SEF),密度频谱阵列(density spectral arrays, DSA),以及爆发抑制(Burst suppression, BS)多种参数来指导麻醉深度管理。实验组目标是将左右SEF保持在10到15之间,PSI保持在25到50之间,并在整个手术过程中避免EEG爆发抑制。如果SEF和PSI相互矛盾(例如,SEF <10而25< PSI < 50),则临床决策基于检查原始EEG波形和DSA评估整体临床情况。

干预措施代码:

Intervention:

During the surgery, we integrate multiple parameters including the patient state index (PSI), 95% spectral edge frequency (SEF), density spectral arrays (DSA), and burst suppression (BS) to guide the management of anesthesia depth.The target for the experimental group is to maintain SEF between 10 and 15, PSI between 25 and 50, and to avoid EEG burst suppression throughout the surgery. If SEF and PSI are contradictory (for example, SEF < 10 while 25 < PSI < 50), clinical decisions are based on examining the raw EEG waveform and DSA to assess the overall clinical situation.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机化,使用Microsoft Excel的RAND函数进行(Microsoft? Office 2010, Microsoft Corporation, Redmond, WA)。区组因素为年龄(65≤Age<80、80≤Age)。我们设置65≤Age<80区组的随机数字为1000-3000,80≤Age区组的随机数为3000-6000;在每个区组由Microsoft Excel的RAND函数各产生一组随机数,随后分别在两个区组内对随机数进行从小到大排序,每个区组序号排名前半段的对应编号的研究对象被分为实验组,每个区组序号排名后半段的对应编号的研究对象被分为对照组。患者入组时通过不透明信封抽取随机数字进行分组。

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

This study adopted block randomization, which was conducted using the RAND function of Microsoft Excel (Microsoft? Office 2010, Microsoft Corporation, Redmond, WA). The block factor was age (65 <= Age < 80, 80 <= Age). We set the random numbers for the 65 <= Age < 80 block within the range of 1000 - 3000, and those for the 80 <= Age block within 3000 - 6000. In each block, a set of random numbers was generated by the RAND function of Microsoft Excel. Subsequently, the random numbers in each block were sorted in ascending order. The research subjects corresponding to the first half of the sequence numbers in each block were classified as the experimental group, while those corresponding to the second half were classified as the control group. At the time of patient enrollment, random numbers were drawn from opaque envelopes for group assignment.

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:

由于本研究为单中心临床试验,原始数据的采集使用CRF表,CRF表的保存和数据的电子录入与管理由本中心具有GCP经验的人员在专用电脑上专人负责。

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

Since this study was a single-center clinical trial, the original data were collected using CRF form, and the preservation of CRF form and the electronic entry and management of data were responsible for by the staff with GCP experience in our center on a dedicated computer.
