队列研究 

Study design:

Cohort study 

研究目的:

探讨心脏手术患者围术期乳酸相关指标(包括但不限于乳酸峰值、平均值、乳酸时间、乳酸清除率等)与术后急性肾损伤(AKI)的发生风险、严重程度及预后的关系,为术后AKI的早期识别和风险分层提供临床依据。  

Objectives of Study:

To explore the relationship between perioperative lactate-related indicators (including but not limited to peak lactate, average lactate, lactate time, lactate clearance rate, etc.) and the risk, severity and prognosis of postoperative acute kidney injury (AKI) in patients undergoing cardiac surgery, and to provide clinical evidence for early identification and risk stratification of postoperative AKI.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 年龄≥18 岁,性别不限; 2. 手术类型:接受心脏手术(包括但不限于:冠状动脉旁路移植术、瓣膜手术、主动脉夹层手术、先天性心脏病矫治术等); 3. 数据完整性:具有完整的围术期临床资料,包括:术前基线肌酐值;术中及术后乳酸监测数据(至少包括术后1h、2h、6h、12h中的3个时间点);术后至少1次肌酐检测值(术后48h内或7天内) 4. 患者或其家属签署知情同意书,自愿参与本研究。

Inclusion criteria

1. Age >= 18 years, gender not limited; 2. Type of surgery: Cardiac surgery (including but not limited to: coronary artery bypass grafting, valve surgery, aortic dissection surgery, congenital heart disease correction surgery, etc.); 3. Data completeness: Complete perioperative clinical data, including: preoperative baseline creatinine level; intraoperative and postoperative lactate monitoring data (including at least 3 time points from 1h, 2h, 6h, and 12h postoperatively); at least one postoperative creatinine test (within 48 hours or 7 days postoperatively); 4. Informed consent must be signed by the patient or their family, indicating voluntary participation in this study.

排除标准:

1. 术前已确诊慢性肾脏病(CKD)3-5期(eGFR<60 mL/min/1.73m2)或接受透析治疗者或术前已有肾损伤患者; 2. 术前 24h 内血清乳酸水平>4 mmol/L 且存在明确病因(如严重感染、休克、肝功能衰竭等); 3. 合并严重肝脏疾病(Child-Pugh 分级 C 级)、恶性肿瘤终末期、凝血功能障碍者; 4. 手术过程中发生严重并发症(如大出血、心跳骤停>10 min 且抢救无效)导致手术中断或术后 24h 内死亡者; 5. 临床资料严重缺失或无法配合完成随访者; 6. 妊娠或哺乳期患者; 7. 同期参与其他干预性临床试验; 8. 拒绝参加。

Exclusion criteria:

1. Patients diagnosed with chronic kidney disease (CKD) stage 3-5 (eGFR < 60 mL/min/1.73m^2) or undergoing dialysis, or those with pre-existing kidney damage; 2. Serum lactate level > 4 mmol/L within 24 hours preoperatively with a clear cause (e.g., severe infection, shock, liver failure, etc.); 3. Patients with severe liver disease (Child-Pugh class C), end-stage malignant tumors, or coagulation disorders; 4. Patients experiencing severe complications during surgery (e.g., massive hemorrhage, cardiac arrest > 10 min with unsuccessful resuscitation) leading to surgical interruption or death within 24 hours postoperatively; 5. Patients with severely missing clinical data or unable to complete follow-up; 6. Pregnant or lactating patients; 7. Patients participating in other interventional clinical trials concurrently; 8. Patients who refuse to participate.
