研究设计:

病例对照研究 

Study design:

Case-Control study 

研究目的:

本研究旨在探讨术前贫血是否为术中输血需求的独立危险因素,明确术前贫血是否增加术中输血需求,探索术前贫血严重程度(Hb水平分层)与输血量的剂量-效应关系,并分析其他预测因素(如凝血功能、手术类型)对术中输血的影响,构建输血风险预测模型,为临床提供参考价值。  

Objectives of Study:

This study aims to explore whether preoperative anemia is an independent risk factor for intraoperative blood transfusion demand, determine whether preoperative anemia increases intraoperative blood transfusion demand, explore the dose-effect relationship between preoperative anemia severity (Hb level stratification) and transfusion volume, analyze the influence of other predictive factors (such as coagulation function and type of surgery) on intraoperative blood transfusion, and build a transfusion risk prediction model. It provides reference value for clinic.

药物成份或治疗方案详述:

采用多中心回顾性病例对照研究设计,纳入2022年至2025年接受择期或急诊手术的成年患者(≥18岁)。病例组为540例术中进行红细胞输注的患者(≥1单位),对照组为540例术中未输血患者,按1:1匹配手术类型、预估失血量和手术紧急程度,样本量平均分配到6个研究中心。术前贫血定义为男性Hb<12 g/dL,女性Hb<11 g/dL,并根据Hb水平进行严重程度分级。通过单因素和多因素分析(Logistic回归和线性回归)评估术前贫血与术中输血需求的关联,并构建输血风险预测模型。 

Description for medicine or protocol of treatment in detail:

A multicenter retrospective case-control design was used to include adult patients (>=18 years of age) undergoing elective or emergency surgery between 2022 and 2025. The case group consisted of 540 patients who received intraoperative red blood cell transfusion (>=1 unit), and the control group consisted of 540 patients who did not receive intraoperative blood transfusion. The sample size was evenly allocated to 6 research centers according to the type of surgery, the estimated blood loss and the degree of urgency of surgery. Preoperative anemia was defined as Hb<12 g/dL in men and Hb<11 g/dL in women, and severity was graded according to Hb levels. Univariate and multivariate analyses (Logistic regression and linear regression) were performed to assess the association between preoperative anemia and the need for intraoperative blood transfusion, and to construct a transfusion risk prediction model. 

纳入标准:

病例组: 1、2022年至2025年接受手术治疗的成年患者(≥18岁) 2、术中进行红细胞输注(根据麻醉记录或血库记录)。 3、术前48小时内检测血红蛋白(Hb)水平。 对照组: 1、术中未接受任何血液制品输注。 2、与病例组匹配:手术类型(如肝胆、胃肠、骨科)、预估失血量(±20%)、手术紧急程度(择期/急诊)。

Inclusion criteria

Case group: 1.Adult patients (>=18 years of age) undergoing surgical treatment between 2022 and 2025 2.Red blood cell transfusion during the operation (according to anesthesia records or blood bank records). 3.Hemoglobin (Hb) levels were measured 48 hours before surgery. Control group: 1.Did not receive any transfusion of blood products during the operation. 2. Matched to case group: type of surgery (e.g., hepatobiliary, gastrointestinal, orthopaedic), estimated blood loss (+-20%), surgical urgency (elective/emergency).

排除标准:

1、术前接受输血或促红细胞生成素治疗。 2、术中失血量>2000 mL(避免极端失血量干扰)。 3、 数据缺失(如术前Hb未检测、输血记录不明确)。 4、有血液系统疾病或凝血功能障碍的患者 。

Exclusion criteria:

1. Preoperative blood transfusion or erythropoietin treatment. 2 .Intraoperative blood loss >2000 mL (to avoid interference with extreme blood loss). 3 . Lack of data (such as preoperative Hb detection, unclear blood transfusion records). 4. Patients with diseases of the blood system or coagulation dysfunction.

随机方法(请说明由何人用什么方法产生随机序列):

该研究为回顾性病例对照研究,属于观察性研究,而非干预性随机对照试验。病例组与对照组的分组基于历史数据(是否输血),而非随机分配。

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

The study was a retrospective case-control study and was observational rather than an interventional randomized controlled trial. The grouping of case and control groups was based on historical data (whether blood was transfused or not) rather than random assignment.
