Cohort study 

研究目的:

本研究拟通过收集与对比肝移植术后无pLT-AKI者、轻度pLT-AKI者和中重度pLT-AKI者的多种围术期暴露因素:包括人口学特征、围术期结构化病历资料、实验室检查、影像学、手术与麻醉记录、肝移植术相关特异性指标(供体特征、术前MELD评分、冷缺血时间、热缺血时间、无肝期时间等)、术中生命体征、血气分析、出入量、用药记录等,并选用新肝期可获得的临床数据作为初步筛选变量,将纳入研究的病例分为模型开发队列和多个时序性验证队列,构建基于临床特征的中重度pLT-AKI的精准分层预警模型。  

Objectives of Study:

This study proposes to select patients undergoing liver transplantation. By collecting and comparing multiple perioperative exposure factors among patients without post-liver transplantation acute kidney injury (pLT-AKI), those with mild pLT-AKI, and those with moderate-to-severe pLT-AKI—including demographic characteristics, structured perioperative medical records, laboratory tests, imaging studies, surgical and anaesthetic records, liver transplantation-specific indicators (donor characteristics, preoperative MELD score, cold ischaemia time, warm ischaemia time, anhepatic period duration, etc.), intraoperative vital signs, blood gas analysis, fluid balance, medication records, etc. Clinical data obtainable during the post-transplant period were selected as preliminary screening variables. Included cases were divided into a model development cohort and multiple sequential validation cohorts to construct a precision stratified early warning model for moderate-to-severe pLT-AKI based on clinical characteristics.

纳入标准:

1.年龄0-80岁;
2.行肝移植手术;

Inclusion criteria

1.Age between 0 to 80 years old; 2.Patietns scheduled for liver transplantation.

排除标准:

1.肝肾联合移植;
2.二次肝移植;
3.缺乏诊断pLT-AKI必要数据者:因各种原因(如术中死亡、术后自动出院等)缺乏足够的围术期血清肌酐值和尿量数据诊断AKI的患者;

Exclusion criteria:

1.Simultaneous liver and kidney transplantation;
2.Re-transplantation;
3.Patients lacking essential data for diagnosing perioperative acute kidney injury (AKI): Individuals for whom sufficient perioperative serum creatinine levels and urine output data are unavailable due to various reasons (such as intraoperative death or spontaneous discharge postoperatively), thereby precluding AKI diagnosis.

The 7th month post-surgery

Measure method:

Data on patient visits, serum creatinine levels, and eGFR within six months post-surgery were collected from outpatient and inpatient medical systems. Cases where serum creatinine and eGFR remained persistently abnormal for three months were classified as AKI progressing to CKD.
