研究目的:

脓毒症是临床危重症,具有高发病率和高死亡率的特点,已成为 ICU 入院和死亡的主要原因,其医疗花费也是最高的。脓毒症的发生主要与全身炎症反应和免疫反应失衡有关,极易导致多器官功能障碍,危及生命。其中最早受打击的器官是肺脏和肠道,因此,积极开发有效治疗及逆转病情的药物迫在眉睫。本团队前期研究发现应用自拟调肠方灌肠可以改善患者肠屏障功能、促进肠道蠕动、抑制炎症反应,从而缓解脓毒症病情进展。本项目拟进一步通过多中心随机对照研究,基于“从肠治肺”探索调肠方灌肠治疗本病的最佳时机和疗程,观察该药是否通过改善炎症、凝血等指标发挥胃肠和肺保护功能,达到改善预后的目的,以期为中西医结合治疗脓毒症提供科学数据。

Objectives of Study:

Sepsis is a clinically critical disease characterized by high morbidity and mortality and has become the leading cause of ICU admission and death as well as the highest medical costs. The occurrence of sepsis is mainly related to the imbalance of systemic inflammatory response and immune response which can easily lead to multi-organ dysfunction and be life-threatening. The lungs and intestines are the first organs to be hit so it is urgent to actively develop drugs that can effectively treat and reverse the disease. Our team's previous research found that the application of self-modulating intestinal enema can improve the intestinal barrier function promote intestinal peristalsis and inhibit inflammatory response thereby alleviating the progression of sepsis. This project intends to further explore the best timing and course of treatment of this disease based on "treating the lungs from the intestines" and observe whether the drug can play a protective function of the gastrointestinal tract and lungs by improving inflammation coagulation and other indicators so as to improve the prognosis in order to provide scientific data for the treatment of sepsis by integrating traditional Chinese and Western medicine.
