Acute kidney injury (AKI) is one of the serious complications of sepsis in clinical practice, and is an important cause of prolonged hospitalization, death, increased medical costs, and a huge medical burden to society. The pathogenesis of AKI associated with sepsis is relatively complex and includes hemodynamic abnormalities due to inflammatory response, oxidative stress, and shock, which subsequently cause a decrease in renal perfusion pressure and eventually lead to ischemia and hypoxia in renal tissue. Active clinical correction of hypotension can effectively improve renal microcirculatory disorders and promote the recovery of renal function. Furthermore, it has been found that in patients with a previous history of hypertension, small changes in blood pressure may be even more deleterious for kidney function. Therefore, the management of blood pressure in patients with sepsis-related AKI will directly affect the short-term and long-term renal function prognosis. This review summarizes the pathophysiological mechanisms of microcirculatory disorders affecting renal function, fluid management, vasopressor, the clinical blood pressure target, and kidney replacement therapy to provide a reference for the clinical management of sepsis-related AKI, thereby promoting the recovery of renal function for the purpose of improving patient prognosis.
急性肾损伤(AKI)是临床实践中脓毒症的严重并发症之一,是导致住院时间延长、死亡、医疗费用增加以及给社会带来巨大医疗负担的重要原因。脓毒症相关的急性肾损伤发病机制较为复杂,包括炎症反应、氧化应激和休克引起的血流动力学异常,进而导致肾灌注压降低,最终致使肾组织缺血缺氧。临床上积极纠正低血压可有效改善肾脏微循环障碍并促进肾功能恢复。此外,研究发现既往有高血压病史的患者,血压的微小变化对肾功能可能更具损害性。因此,脓毒症相关急性肾损伤患者的血压管理将直接影响肾功能的短期和长期预后。本综述总结了影响肾功能的微循环障碍的病理生理机制、液体管理、血管升压药、临床血压目标以及肾脏替代治疗,为脓毒症相关急性肾损伤的临床管理提供参考,从而促进肾功能恢复以改善患者预后。
