研究目的: |
本研究旨在探讨心脏手术术后早发型(术后48小时内)和晚发型(术后48小时至7天内)急性肾损伤(AKI)的相关危险因素,并重点分析术中因素的影响,揭示手术过程中可干预的危险因素,帮助临床医生在术中采取有效预防措施。通过建立基于术前和术中数据的机器学习预测模型,并使用SHAP方法解释模型结果,帮助临床医生识别高风险患者,制定个性化的预防和治疗方案,从而改善患者预后。 |

|
Objectives of Study: |
The purpose of this study was to investigate the risk factors related to early-onset (within 48 hours after surgery) and late-onset (within 48 hours to 7 days after surgery) of acute kidney injury (AKI) after cardiac surgery, and to focus on the analysis of the influence of intraoperative factors, to reveal the risk factors that can be intervened during surgery, and to help clinicians take effective preventive measures during surgery. By establishing a machine learning prediction model based on preoperative and intraoperative data, and using the SHAP method to interpret the model results, it helps clinicians identify high-risk patients and formulate personalized prevention and treatment plans to improve patient outcomes. |
