慢性肾脏病基础上出现急性肾损伤相关因素的临床分析

目的 探讨慢性肾脏病(CKD)基础上出现急性肾损伤(AKI)的相关危险因素,为早期干预、延缓CKD进程提供依据.方法 将127例CKD患者根据有无合并AKI分组,未合并AKI者60例(CKD组),合并AKI者67例(A/C组),再将MC组患者按年龄分组,其中＜60岁35例(非老年组),≥60岁32例(老年组).就其原发病、诱发因素等进行分析.结果 不同年龄组CKD患者诱发AKI的病因有不同特点;CKD基础上出现AKI相关危险因素如严重感染、血容量不足、心力衰竭、使用肾毒性药物的OR值分别为5.236、5.083、8.283、5.246,P＜0.05.结论 CKD患者易受多种因素影响,重视CKD基础上出现AKI的高危因素并及早发现,争取在短时间内纠正危险因素和保护肾功能,对延缓CKD的进程和改善患者的预后有重要意义.

Clinical analysis of risk factors of acute kidney injury in patients with chronic kidney disease

Objective To evaluate the risk factors of patients with acute kidney injury (AKI) in patients with chronic kidney disease (CKD) for the early detection and early treatment of CKD.Methods One hundred and twenty-seven CKD patients were divided into groups according to AKI existing, 60 cases with out AKI (CKD group), 67 cases with AKI (A/C group) and then A/C group patients were divided into non-older age group (35 cases, ＜60 years old) and older age group (32 cases, ≥60 years old).The protopathy, causative factors and so on were analyzed.Results There was different causative factors in different age group.Logistic regression model indicated that the major risk flactors of AKI in CKD were severe infection (OR = 5.236),hypovolemia (OR = 5.083 ),heart failure (OR = 8.283) and using renal toxicity medicine (OR = 5.246),P ＜ 0.05.Conclusion The major risk factors of AKI in CKD patients include severe infection, hypovolemia, heart failure and renal toxicity medicine.
