PICCO在危重症患者中应用的研究进展

Research progress of application PICCO in critically ill patients

危重症患者往往出现血流动力学不稳定,如何稳定血流动力学是临床治疗的关键,而有效的血流动力学监测则是治疗成功的前提。脉搏指示连续心排量测量(PICCO),通过经肺热稀释法获得一系列临床监测指标,包括:心脏射血分数(GEF)、心功能指数(CFI)、全心舒张末期容积(GEDV)、胸腔内血容积(ITBV)、血管外肺水(EVLW)等数据,进而指导危重症患者液体复苏。

Hemodynamically unstable is a common clinical manifestation in critically ill patients,and how to provid strong hemodynamic support is a key of clinical treatment,but value hemodynamic assessment of and monitoring is the precondition of treatment success. Pulse index continuous cardiac output（ PICCO）,can obtain a series of clinical monitoring indexes through a lung heat dilution method,such as： heart ejection fraction（ GEF）,cardiac function index（ CFI）,global end-diastolic volume（ GEDV）,intrathoracic blood volume（ ITBV）,extravascular lung water（ EVLW）,and other data,fluid resuscitation and then guide the liquid recovery in critically ill patients.
