研究目的:

通过颈动脉血流测定来监测大脑的血流、术中监测脑饱和度、S100β蛋白及MMSE评分等指标的变化,来进一步探索控制性降压下脊柱手术患者大脑的血流和患者术后认知功能的关系和影响,为临床安全使用控制性降压这一技术提供理论依据。  

Objectives of Study:

Carotid blood flow measurement was used to monitor brain blood flow, intraoperative monitoring of brain saturation, S100β protein and MMSE score and other indexes, so as to further explore the relationship and influence between blood flow in the brain of patients undergoing controlled blood pressure lowering and postoperative cognitive function, so as to provide a theoretical basis for the safe use of controlled blood pressure lowering technology.

药物成份或治疗方案详述:

硝酸甘油0.5μg/(kg·min)、艾司洛尔2.5μg/(kg·min)(硝酸甘油:艾司洛 尔为1:5),微量泵输注速度硝酸甘油0.5μg/(kg·min)为初始量进行控制性降压,并根据血压逐渐增加剂量使平均动脉压(MAP)降至基础值的70%~80%,从开始降压到达到稳定的目标血压在15min内完成,此后根据术中心率和血压调整硝酸甘油剂量。 

Description for medicine or protocol of treatment in detail:

Nitroglycerin 0.5μg/(kg·min), esmolol 2.5μg/(kg·min) (nitroglycerin: 1:5 for esloer), micropump infusion speed nitroglycerin 0.5μg/(kg·min) for the initial amount of controlled blood pressure, and gradually increase the dose according to blood pressure to reduce the average arterial pressure (MAP) to 70%~80% of the basal value, from the beginning of lowering blood pressure to reaching a stable target blood pressure within 15min, Thereafter, the dose of nitroglycerin is adjusted according to the central rate and blood pressure. 

纳入标准:

年龄>18岁、ASA分级Ⅰ~Ⅱ级、受教育年限≥6年。

Inclusion criteria

Age> 18 years old, ASA grade I.~II., years of education≥ 6 years.
