Objective To explore the high-risk factors affecting the occurrence of acute kidney injury in patients with sepsis,and to target and analyse protective measures. Methods We retrospectively analysed the clinical data of 84 sepsis patients admitted to the Second Affiliated Hospital of Guangdong Medical University from June 2022 to June 2024,and classified them into occurrence group and non-occurrence group according to the occurrence of acute kidney injury,and collected general data such as patients' gender,age,mechanical ventilation,history of smoking,history of alcohol consumption,history of chronic renal disease,comorbid malnutrition,Acute Physiology and Chronic Health Condition Scoring System II score ( APACHE II) score,cystatin level and other general information to carry out logistic regression analysis to analyse the high-risk factors affecting the occurrence of acute kidney injury in sepsis patients. Results Among 84 patients with sepsis,28 cases of acute kidney injury occurred,with an incidence rate of 33.33%. Univariate factors showed no statistical difference between the two groups in terms of gender,age,mechanical ventilation,smoking history,alcohol consumption history,and combined diabetes mellitus (P>0.05);statistically significant differences were found in the two groups in terms of combined lung infections,combined hyperlactatemia,history of chronic renal disease,combined malnutrition,APACHE II scores,cystatin levels,and other general information. cystatin levels were statistically different (P<0.05);combined lung infection,combined hyperlactatemia,history of chronic kidney disease,combined malnutrition,APACHE II score≥ 18,and cystatin≥2 mg/L were all high-risk factors for the occurrence of acute kidney injury in patients with sepsis (P<0.05). Conclusion Acute kidney injury in patients with sepsis is associated with combined lung infection,combined hyperlactatemia,history of chronic kidney disease,combined malnutrition,APACHE II score,and cystatin level. The clinic needs to take protective measures accordingly to reduce the risk of acute kidney injury.
