干预措施:

自体血小板分离组。术中麻醉方式和围术期管理同对照组,除传统的血液管理策略,另外给予术前自体血小板分离技术,术中麻醉诱导完成后,肝素化之前分离患者自体血小板(机器型号:LivaNova XTRA);。麻醉后肝素化前分离20~30%血容量制备富含血小板血浆,震荡保存备用,待术毕中和鱼精蛋白后回输给患者;红细胞则立即回输。

干预措施代码:

Intervention:

Anesthesia and perioperative management were identical to the control group. In addition to conventional blood management strategies, patients received preoperative autologous platelet apheresis. After anesthesia induction and before systemic heparinization, autologous platelets were collected using the LivaNova XTRA device. Approximately 20–30% of the estimated blood volume was separated to prepare platelet-rich plasma, which was stored with gentle agitation and reinfused after surgery following protamine reversal. Red blood cells were reinfused immediately after separation.

干预措施:

采用插管全麻联合体外循环方式。快速诱导后,环泊酚、七氟烷、舒芬太尼和罗库溴铵维持麻醉。常规监测上下肢IBP、ECG、TEE、SpO2、CVP、HR、体温(鼻咽温、膀胱温)等参数。按传统模式根据术中血流动力学和内环境变化情况进行围术期输血管理。术中行常规血液回收,全程应用氨甲环酸(30mg/kg静脉负荷量、16mg/kg/h静脉维持量和2mg/kg 体外循环预充量)。体外循环常规预充1500ml;使用集成式氧合器,不强调超滤。术毕依据辅助决策系统进行精准肝素-鱼精蛋白中和,使用凝血功能监测技术等即时检测技术,根据患者凝血功能的异常而选择性输入对应血制品。术毕转入心外科ICU,常规采用舒芬太尼持续静脉镇痛,持续泵注环泊酚维持镇静至拔除气管导管。

干预措施代码:

Intervention:

General anesthesia with endotracheal intubation and cardiopulmonary bypass was used. Anesthesia was maintained with propofol, sevoflurane, sufentanil, and rocuronium. Standard monitoring included IBP, ECG, TEE, SpO?, CVP, HR, and body temperature (nasopharyngeal and bladder). Perioperative transfusion was managed according to conventional protocols based on hemodynamic and metabolic changes. Intraoperative blood salvage was routinely performed. Tranexamic acid was administered (30 mg/kg loading, 16 mg/kg/h maintenance, 2 mg/kg added to CPB priming). CPB was primed with 1500 mL; integrated oxygenators were used without emphasis on ultrafiltration. At the end of surgery, heparin was reversed using a decision-support-guided protamine dosing strategy. Coagulation was assessed using point-of-care testing to guide selective transfusion. Postoperatively, patients were transferred to the ICU with continuous sufentanil for analgesia and propofol infusion for sedation until extubation.

随机方法(请说明由何人用什么方法产生随机序列):

根据计算机生成的随机数表进行受试者分配,按1:1比例分配至试验组(自体血小板分离组,APP)和对照组(Control)。随机序列由独立统计人员使用统计软件R4.4.0预先生成并封存。

Randomization Procedure (please state who generates the random number sequence and by what method):

Participants will be randomly assigned in a 1:1 ratio to the intervention group (autologous platelet apheresis group, APP) or the control group based on a computer-generated randomization list. The random sequence will be pre-generated and sealed by an independent statistician using R software (version 4.4.0).

盲法:

本研究采取部分盲法设计以降低偏倚风险。负责记录的医师负责录入患者的一般资料,并按照患者的编号提交分组信息;操作医师根据分组方案确认后实施相应的干预措施;随访医师按预定时间节点对接受干预的患者进行评估,此三位医师各自独立。由于操作医师需实施相应干预措施,因此无法对患者分组持盲。为尽量减少偏倚,患者、分组设计者、随访医师对患者的分组情况均持盲。试验过程中若因医疗需要被迫揭盲,须完整记录揭盲原因、时间、相关人员,并评估对结果的潜在影响。

Blinding:

A partial blinding design is adopted in this study to minimize the risk of bias. The data-recording physician is responsible for entering the patient's baseline information and submitting the grouping information according to the patient’s study number. The operating physician confirms the group assignment and performs the corresponding intervention, while the follow-up physician independently evaluates patients at predefined time points. These three physicians operate independently of each other. As the operating physician must deliver the intervention, blinding to group allocation is not feasible for this role. To minimize potential bias, the patients, group assignment personnel, and follow-up physicians will remain blinded to the group allocation. In cases where unblinding is medically necessary during the study, the reason, time, personnel involved, and potential impact on study outcomes must be thoroughly documented and evaluated.
