研究目的:

主要研究目的:评估早期静脉注射硫酸镁与安慰剂相比,在中重度创伤性脑损伤(TBI)患者中的疗效,主要通过层次化复合终点进行评估,包括28天全因死亡率、7天内急性呼吸窘迫综合征(ARDS)发生率,以及氧合指数(PaO?/FiO?)曲线下面积(AUC)变化。 次要研究目的:评估硫酸镁对中重度TBI患者临床预后的综合影响,包括ICU住院时间、总住院天数、28天存活率、并发症发生率(如房颤、肾衰竭和癫痫)、以及神经功能评分(GCS和GOS-E)的变化。探索硫酸镁的抗炎和脑-肺保护机制,通过检测血清炎症因子(IL-6、IL-8、TNF-α、IL-1β、CRP、IL-10)、氧化应激标志物(MDA)、神经肽(SP)、脑损伤标志物(GFAP/UCH-L1)和肺损伤标志物(sRAGE)的动态变化。  

Objectives of Study:

The primary research objective is to evaluate the efficacy of early intravenous magnesium sulfate compared with placebo in patients with moderate to severe traumatic brain injury (TBI), mainly through a hierarchical composite endpoint, including 28-day all-cause mortality, the incidence of acute respiratory distress syndrome (ARDS) within 7 days, and the change in the area under the curve (AUC) of the oxygenation index (PaO?/FiO?).The secondary research objective is to assess the comprehensive impact of magnesium sulfate on the clinical prognosis of patients with moderate to severe TBI, including ICU length of stay, total hospital stay, 28-day survival rate, incidence of complications (such as atrial fibrillation, renal failure, and epilepsy), and changes in neurological function scores (GCS and GOS-E). To explore the anti-inflammatory and brain-lung protective mechanisms of magnesium sulfate, dynamic changes in serum inflammatory factors (IL-6, IL-8, TNF-α, IL-1β, CRP, IL-10), oxidative stress markers (MDA), neuropeptides (SP), brain injury markers (GFAP/UCH-L1), and lung injury markers (sRAGE) will be detected.

随机方法(请说明由何人用什么方法产生随机序列):

采用分层区组随机化方法,由一位独立统计学家使用R软件(版本4.3.3)生成随机分配序列。分层因素为基线格拉斯哥昏迷评分(3-8分 vs 9-12分)。在每个分层内,采用1:1的比例,使用区组长度为4和6(随机变化)将患者随机分配至硫酸镁组或安慰剂组。分配序列被密封于按顺序编号、不透光、防拆封的信封中,由中心药房独立药师保管,以保证分配隐蔽。

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

A stratified block randomization was performed by an independent statistician using R software (version 4.3.3). Patients were stratified by baseline Glasgow Coma Scale score (3–8 vs. 9–12). Within each stratum, patients were randomly assigned in a 1:1 ratio to the magnesium sulfate group or the placebo group using variable block sizes of 4 and 6. The allocation sequence was concealed in sequentially numbered, opaque, sealed envelopes, which were kept by an independent pharmacist at the central pharmacy.
