[摘要] 膿毒癥(sepsis)是宿主對(duì)感染的反應(yīng)失調(diào),并產(chǎn)生危及生命的器官功能障礙,常發(fā)生在燒傷、感染、多發(fā)傷等臨床急危重疾病的基礎(chǔ)上,也是導(dǎo)致多器官功能障礙綜合征(MODS)的重要原因之一,病情兇險(xiǎn),臨床病死率高。膿毒癥誘導(dǎo)的心肌抑制(sepsis-induced myocardial dysfunction,SIMD)是嚴(yán)重膿毒癥和膿毒性休克常見(jiàn)的并發(fā)癥之一,是導(dǎo)致膿毒癥多器官功能障礙及其病死率增加的重要因素。一種新型鈣增敏劑——左西孟旦,在失代償性心衰治療中發(fā)揮了較好的療效,目前在膿毒癥中也得到一定的應(yīng)用,但是存在一定的爭(zhēng)議。近年來(lái)對(duì)左西孟旦在膿毒癥中的作用,國(guó)內(nèi)外進(jìn)行多項(xiàng)臨床試驗(yàn),現(xiàn)就其在膿毒癥中的作用進(jìn)展作一綜述。

[Abstract] Sepsis is the response disorder of the host to infection, which produces life-threatening organ dysfunction and often occurs on the basis of clinical acute and critical diseases including burns, infections, multiple injuries, and is one of the important reasons leading to multiple organ dysfunction syndrome(MODS). The disease is dangerous and has high clinical mortality. Sepsis-induced myocardial dysfunction(SIMD) is one of the most common complications of severe sepsis and septic shock, which is an important factor leading to the increase of multiple organ dysfunction and the mortality of sepsis. A new calcium sensitizer——levosimendan plays a very good effect in the treatment of decompensated heart failure, and also has a certain application in sepsis. But there is a certain controversy. In recent years, a number of clinical trials at home and abroad on the role of levosimendan in sepsis have been carried out. The progress of the role of levosimendan in the treatment of sepsis will be reviewed in this paper.

膿毒癥是宿主對(duì)感染的反應(yīng)失調(diào),產(chǎn)生危及生命的器官功能障礙[1],可發(fā)展為嚴(yán)重膿毒癥和膿毒性休克(由于既往的研究大都是在sepsis3.0定義之前,本文暫保留了嚴(yán)重膿毒癥的概念)。膿毒癥誘導(dǎo)的心肌抑制(sepsis-induced myocardial dysfunction,SIMD)主要表現(xiàn)為左、右心室射血分?jǐn)?shù)的下降及舒張功能的減退,是膿毒癥和膿毒性休克常見(jiàn)的并發(fā)癥[2]。臨床上約50%的膿毒性休克患者存在不同程度的心功能抑制[3],一旦合并心肌抑制,其死亡率高達(dá)70%~90%[4]。所以,早發(fā)現(xiàn)、早治療、減少心肌耗氧量、提升心輸出量以及保護(hù)心臟功能顯得尤為重要。左西孟旦作為一種新型鈣增敏劑,多用于失代償性心衰[5]、冠狀動(dòng)脈疾病[6]以及心臟手術(shù)后[7],最近其在嚴(yán)重膿毒癥和膿毒性休克中的應(yīng)用也越來(lái)越受到人們的關(guān)注。……
