摘　　要：目的确定腰椎后路融合术术中输血的危险因素,并建立腰椎后路融合术术中输血的列线图。方法回顾性研究2021年1月—2021年8月采用腰椎后路融合术治疗的304例患者,进行单因素分析与多因素Logistic回归分析,以确定输血的危险因素,并建立列线图模型来预测输血的风险。结果在304例患者中,73例接受了输血。统计分析表明,术前血红蛋白(Hb)、手术时间、是否使用氨甲环酸是输血的独立预测因素。列线图的C指数为0.725。结论术前Hb高、手术时间短、使用氨甲环酸会明显降低输血率,建立了列线图模型,用于评估行腰椎融合术患者的输血风险,并为临床医生进行围手术干预提供指导,以降低输血的发生率。Objective To determine the risk factors of blood transfusion during posterior lumbar spinal fusion and establish a nomogram for blood transfusion.Methods A retrospective analysis of 304 patients treated with posterior lumbar fusion from January 2021 to August 2021 was conducted.Univariable and multivariable logistic regression analysis were conducted to identify risk factors for blood transfusion,and a nomogram was constructed to predict the risk of blood transfusion.Results Of the 304 patients,73 received blood transfusions.Statistical analysis showed that preoperative hemoglobin(Hb),operation time,and whether to use tranexamic acid were independent predictors of blood transfusion.The C index of the nomogram was 0.725.Conclusion The preoperative Hb is high,the operation time is short,and the use of tranexamic acid can significantly reduce the blood transfusion rate.A nomogram has been established to assess the risk of blood transfusion in patients undergoing posterior lumbar spinal fusion and provide guidance for clinicians to provide perioperative intervention and reduce the incidence of blood transfusion.
