研究目的:

本研究旨在通过联合应用脑氧饱和度(rSO₂)、脑电图(EEG)及经颅多普勒超声(TCD)三种监测技术,构建多模态脑功能监测体系,并以此为基础制定目标导向管理策略,用于成人体外循环心脏直视术后ICU患者的谵妄防治。研究拟通过随机对照试验,比较联合监测干预组与常规治疗组在谵妄发生率、严重程度、神经认知功能及临床结局等方面的差异,探讨多模态监测对谵妄的干预效果。同时,结合血液标志物检测,阐明监测指标与谵妄发生的潜在机制,并构建谵妄风险预测模型,为实现高危患者的早期识别与精准干预提供依据,最终提升患者预后并优化临床管理流程。  

Objectives of Study:

The purpose of this study was to construct a multimodal brain function monitoring system by combining three monitoring techniques : cerebral oxygen saturation ( rSO₂ ), electroencephalogram ( EEG ) and transcranial Doppler ultrasound ( TCD ). Based on this, a goal-oriented management strategy was developed for the prevention and treatment of delirium in ICU patients after open heart surgery with cardiopulmonary bypass. The study intends to compare the differences in the incidence, severity, neurocognitive function and clinical outcome of delirium between the combined monitoring intervention group and the conventional treatment group through randomized controlled trials, and to explore the intervention effect of multimodal monitoring on delirium. At the same time, combined with the detection of blood markers, the potential mechanism of monitoring indicators and delirium was clarified, and a delirium risk prediction model was constructed to provide a basis for early identification and precise intervention of high-risk patients, and ultimately improve the prognosis of patients and optimize the clinical management process.

干预措施:

该组患者在术后进入ICU后,将同时连接脑氧饱和度(rSO2)监测仪、脑电图(EEG)监测仪和经颅多普勒超声(TCD)监测设备,进行持续、同步的多模态脑功能监测。干预团队将依据实时监测数据,执行以下目标导向的针对性管理策略: 1.基于脑氧饱和度(rSO2)的干预:当监测显示患者局部脑氧饱和度低于预设的个体化阈值时,立即采取干预措施以提升脑氧供,具体方法包括:调整吸入氧浓度(FiO)、进行液体复苏(补液)、或酌情使用血管活性药物以改善脑灌注。 2.基于脑电图(EEG)的干预:实时分析脑电活动特征,若出现提示麻醉过深的迹象(如脑电爆发抑制时间过长),或提示麻醉过浅/镇静不足的迹象(如脑电频率过快),则及时、精确地调整镇静/麻醉药物的输注剂量或方案,以维持适宜的麻醉镇静深度。 3.基于经颅多普勒超声(TCD)的干预:根据TCD监测到的脑血流速度变化,若发现血流速度异常降低(提示可能存在脑灌注不足)或异常升高(提示可能存在脑血管痉挛或过度灌注),则优化脑灌注管理策略,例如通过调整血压管理目标、控制血容量及心脏前后负荷等方式进行干预。

干预措施代码:

Intervention:

After entering the ICU after surgery, this group of patients will be simultaneously connected to the brain oxygen saturation(rSO2) monitor, electroencephalogram ( EEG ) monitor and transcranial Doppler ultrasound ( TCD ) monitoring equipment for continuous and synchronous multimodal brain function monitoring. The intervention team will implement the following goal-oriented targeted management strategies based on real-time monitoring data : 1.Intervention based on cerebral oxygen saturation (rSO2) : When the monitoring showed that the patient 's local cerebral oxygen saturation was lower than the preset individualized threshold, immediate intervention measures were taken to improve the cerebral oxygen supply, including : adjusting the inhaled oxygen concentration ( FiO ), performing fluid resuscitation ( rehydration ), or using vasoactive drugs as appropriate to improve cerebral perfusion. 2.Intervention based on electroencephalogram ( EEG ) : The characteristics of EEG activity were analyzed in real time. If there were signs of too deep anesthesia ( such as too long inhibition time of EEG burst ) or too shallow anesthesia / insufficient sedation ( such as too fast EEG frequency ), the infusion dose or regimen of sedative / anesthetic drugs should be adjusted in time and accurately to maintain the appropriate depth of anesthesia and sedation. 3.Intervention based on transcranial Doppler ultrasound ( TCD ) : According to the changes of cerebral blood flow velocity monitored by TCD, if it is found that the blood flow velocity is abnormally reduced ( suggesting that there may be insufficient cerebral perfusion ) or abnormally elevated ( suggesting that there may be cerebral vasospasm or hyperperfusion ), the cerebral perfusion management strategy is optimized, for example, by adjusting the blood pressure management target, controlling blood volume and cardiac load.

干预措施:

该组患者在术后进入ICU后,不接受脑氧饱和度(rSO2)、脑电图(EEG)及经颅多普勒超声(TCD)的联合监测与基于此的专门管理。 其干预措施完全遵循当前临床常规标准,主要包括: 1.监测手段:采用传统的生命体征监护,包括持续监测心率、血压、呼吸频率、脉搏血氧饱和度(SpO2),并定期进行血气分析等常规实验室检查。 2.决策依据:所有的治疗与护理决策不依据上述多模态脑功能监测的实时数据进行调整。 3.干预性质:按照科室既定的术后常规治疗方案和护理路径执行,例如: 根据血压和心率的常规监测结果,按标准使用血管活性药物或调整容量;根据血气分析结果和SpO2,常规调整呼吸机参数或氧疗方案;镇静、镇痛药物的使用遵循固定的评分(如RASS评分)或常规医嘱方案,而非针对脑电图特征的实时调整。

干预措施代码:

Intervention:

Patients in this group did not receive joint monitoring and specialized management of cerebral oxygen saturation ( rSO2 ), electroencephalogram ( EEG ) and transcranial Doppler ultrasound ( TCD ) after entering the ICU after surgery. Its interventions fully comply with the current clinical routine standards, including : 1.Monitoring methods : Traditional vital signs monitoring, including continuous monitoring of heart rate, blood pressure, respiratory rate, pulse oxygen saturation ( SpO2 ), and regular blood gas analysis and other routine laboratory tests. 2.Decision-making basis : All treatment and nursing decisions were not adjusted according to the real-time data of multimodal brain function monitoring. 3.Intervention nature : According to the established routine postoperative treatment plan and nursing path of the department, for example, according to the routine monitoring results of blood pressure and heart rate, vasoactive drugs or volume adjustment were used according to the standard ; according to the results of blood gas analysis and SpO2, the ventilator parameters or oxygen therapy were routinely adjusted. The use of sedative and analgesic drugs followed a fixed score ( such as RASS score ) or a routine doctor 's advice regimen, rather than real-time adjustment for EEG characteristics.

随机方法(请说明由何人用什么方法产生随机序列):

1. 随机序列产生者:由课题研究团队中不直接参与患者招募与临床干预的专职统计人员负责生成随机分配序列。 2. 随机序列产生方法:采用计算机生成的随机数字表法。使用统计软件SPSS生成一组与预计样本量(N=60)相对应的、无规律的数字序列。将每个随机数字按事先设定的规则(奇数分入A组,偶数分入B组)转换为对应的组别分配结果(即“联合监测目标导向管理组”或“常规治疗组”)。

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

1.Random sequence generator : Full-time statisticians who are not directly involved in patient recruitment and clinical intervention in the research team are responsible for generating random distribution sequences. 2.Random sequence generation method : A computer-generated random number table method was used. The statistical software SPSS was used to generate a set of irregular numerical sequences corresponding to the expected sample size ( N = 60 ). Each random number was converted into the corresponding group allocation results ( i.e., ' joint monitoring goal-oriented management group ' or ' conventional treatment group ' ) according to pre-set rules ( odd number into group A, even number into group B ).
