Microcirculation monitoring and management of sepsis: from a clinical practice perspective
-
摘要: 脓毒症是重症监护治疗病房患者死亡的主要原因之一,多年来为解决这一难题研究人员提出了多种治疗方法,但脓毒症尤其是脓毒性休克患者的预后并未得到改善。随着对脓毒症研究的不断深入,发现微循环障碍是脓毒症导致多器官衰竭的关键,而脓毒症病死率与器官衰竭密切相关,因此在脓毒症治疗过程中微循环的监测和管理尤为重要。本文就临床实践中可用的微循环监测手段与管理方法进行综述,供应用参考。Abstract: Sepsis is one of the main causes of death in intensive care unit patients. Over the years, researchers have proposed a variety of treatment methods to solve this problem, but the prognosis of patients with sepsis, especially septic shock, has not improved. With the deepening of research on sepsis, it has been found that microcirculation disorder is the key to multiple organ failure caused by sepsis, and the mortality rate of sepsis is closely related to organ failure. Therefore, monitoring and management of microcirculation is particularly important in the course of sepsis treatment. This article reviews the microcirculation monitoring tools and management methods available in clinical practice for reference.
