Description for medicine or protocol of treatment in detail:

 

纳入标准:

术中和术后72h 可能需输注同种异体 红细胞悬液,且 Hb 低于10g/dL 者(若围手术期应用自体血回输, 则自体血全部回输后Hb 低于10g/dl 者),将被正式纳入并随机分组进入研究。若患者在行自体血回输的同时发生急性失血而需考虑输血,则在该时点的自体血回输后 Hb 低于10g/dl者也将纳入。符合入选标准的患者按照随机号入组。3组按照1:1:1分配患者,通过随机化使各治疗区组达到平衡。(应用区组大小可变的置换区组随机化, 1:1:1,随机化根据性别、骨折部位(股骨颈、转子间或转子下骨折 进行分层,并通过数据管理系统集中进行)。

Inclusion criteria

Patients who may require allogeneic red blood cell suspension transfusion during surgery and within 72 hours postoperatively, and whose hemoglobin (Hb) level is below 10 g/dL (if autologous blood reinfusion is used perioperatively, then whose Hb remains below 10 g/dL after the complete reinfusion of autologous blood), will be formally enrolled and randomized into the study. If a patient experiences acute blood loss necessitating transfusion consideration while undergoing autologous blood reinfusion, they will also be enrolled if their Hb level is below 10 g/dL after the autologous blood reinfusion at that time point. Eligible patients will be assigned to groups according to their randomization number. Patients will be allocated into three groups in a 1:1:1 ratio, using randomization to balance the treatment groups. (A permuted block randomization with variable block size, 1:1:1 ratio, stratified by gender and fracture site (femoral neck, intertrochanteric, or subtrochanteric fracture), will be performed centrally through a data management system.)

排除标准:

患有血液系统疾病,血红蛋白携氧能力缺陷(高铁血红蛋白血症等),急性冠脉综合症,心肺功能不全患者,肾功能不全, 肿瘤多部位多发或/和肿瘤转移等。

Exclusion criteria:

Patients with hematological diseases, impaired hemoglobin oxygen-carrying capacity (such as methemoglobinemia), acute coronary syndrome (ACS), cardiopulmonary insufficiency, renal insufficiency, and multiple tumors and/or tumor metastases.
