连续肾脏替代疗法对合并急性肾损伤的MODS患者预后的影响

目的 探讨连续肾脏替代疗法（CRRT）对合并急性肾损伤（AKI）的多器官功能障碍综合征（MODS）患者预后的影响.方法 选取本院重症监护行CRRT治疗的59例合并AKI的MODS患者.观察患者的一般情况、CRRT治疗前24h内的指标,对所有入选患者进行改善全球肾脏病预后组织（KDIGO）分期,同时计算平均每日液体平衡（MFB）,并对患者的预后进行统计.结果 不同KDIGO分期患者在序贯器官功能衰竭评分（SOFA）、急性生理和慢性健康评分（APACHE Ⅱ）评分、使用血管活性药物例数、少尿和患者死亡例数随着KDIGO分期的加重而显著增加（P＜0.05）;死亡患者中的KDIGO Ⅲ期的例数、APACHE Ⅱ评分、衰竭器官数、使用血管活性药物例数、少尿例数和MFB都明显高于存活患者（P＜0.05）;KDIGO Ⅲ期、器官衰竭数、少尿和MFB是影响合并AKI的MODS患者行CRRT治疗的预后的独立危险因素.结论 KDIGO分期对行CRRT的合并AKI的MODS患者预后有一定的预测价值,而行CRRT前的脏器衰竭数、少尿和平均每日液体平衡三项指标也是影响合并AKI的MODS患者预后的独立危险因素.

Prognostic effects of continuous renal replacement therapy on multiple organ dysfunction complicated with acute kidney injury

Objective To investigate the prognostic effects of continuous renal replacement therapy on multiple organ dysfunction complicated with acute kidney injury.Methods Fifty nine patients who were diagnosed with multiple organ dysfunction syndrome （MODS） complicated with acute kidney injury （AKI） and underwent continuous renal replacement therapy （CRRT） were selected and grouped according to the Kidney Disease Improving Global Outcomes （KDIGO） staging.Their clinical data before CRRT were collected.The patients were grouped according to the Intensive Care Unit （ICU） prognosis,namely death and survival.The differences between two groups were analyzed.The multinomial logistic regression analysis was performed to explore the prognostic factors.Results With the increase of KDIGO stage,the Acute Physiology And Chronic Health Evaluation Ⅱ （APACHEII） score,Sequential Organ Failure Assessment （SOFA） score,the need for vasoactive drugs,and the number of cases with oliguria and ICU mortality rates showed an increasing trend,and those differences were statistically significant （P 〈 0.05）.After multivariate analysis,KDIGO Ⅲ stage,the number of failed organs,oliguria,and the mean daily fluid balance were independent risk factors of death in patients who were diagnosed with MODS complicated with AKI and underwent CRRT.Conclusions The KDIGO classification plays an important role in predicting the prognosis of patients with MODS complicated with AKI in need of CRRT.The number of failed organs,oliguria,and the mean daily fluid balance are also the risk factors for prognosis.
