研究目的:

本研究拟通过随机、单盲、安慰剂对照Ⅱ期临床试验,评估硫辛酸辅助治疗脓毒症相关肠损伤患者的临床疗效与安全性。这有助于阐明脓毒症肠功能障碍的氧化应激机制与治疗新靶点,为后续多中心研究提供科学依据。  

Objectives of Study:

This study intends to conduct a randomized, single-blind, placebo-controlled phase II clinical trial to evaluate the clinical efficacy and safety of lipoic acid as adjuvant therapy in patients with sepsis-associated intestinal injury. It helps clarify the oxidative stress mechanism and novel therapeutic targets of sepsis-induced intestinal dysfunction, and provides scientific evidence for subsequent multicenter studies.

盲法:

研究采用单盲设计,盲法对象为研究团队(研究者、研究护士、实验室检测人员),受试者不设盲(因无法对受试者完全隐瞒干预措施,但需告知受试者可能接受试验药物或安慰剂,避免受试者主观偏倚),全程确保盲法的稳定性和有效性

Blinding:

This study adopts a single-blind design. The blinding is implemented among all research staff, including investigators, research nurses and laboratory testers, while participants are unblinded. Since it is impossible to completely conceal the intervention measures from participants, they will be informed that they may receive either the investigational drug or placebo to avoid subjective bias, so as to ensure the stability and effectiveness of blinding throughout the whole study.
