Administration of fluid is a cornerstone of supportive care for sepsis. Current guidelines suggest a protocolized approach to fluid resuscitation in sepsis despite a lack of strong physiological or clinical evidence to support it. Both initial and ongoing fluid resuscitation requires careful consideration, as fluid overload has been shown to be associated with increased risk for mortality. Initial fluid resuscitation should favor balanced crystalloids over isotonic saline, as the former is associated with decreased risk of renal dysfunction. Traditionally selected resuscitation targets, such as lactate elevation, are fraught with limitations. For developing or established septic shock, a focused hemodynamic assessment is needed to determine if fluid is likely to be beneficial. When initial fluid therapy is unable to achieve the blood pressure goal, initiation of early vasopressors and admission to intensive care should be favored over repetitive administration of fluid.
液体管理是脓毒症支持性治疗的基石。尽管缺乏强有力的生理或临床证据支持,但目前的指南建议对脓毒症采用规范化的液体复苏方法。初始和持续的液体复苏都需要仔细考虑,因为已经证明液体超负荷与死亡率增加有关。初始液体复苏应优先选择平衡晶体液而不是等渗盐水,因为前者与肾功能障碍风险降低有关。传统选择的复苏目标,如乳酸升高,存在诸多局限性。对于新发或持续的感染性休克,需要进行有针对性的血流动力学评估,以确定液体治疗是否可能有益。当初始液体治疗无法达到血压目标时,应优先考虑早期使用血管加压素和收入重症监护病房,而不是反复给予液体。
