This study aims to identify the predictors of HBL in spinal surgery.Methods Medical records were retrospectively retrieved to collect the data of patients who undergoing posterior thoracic and lumbar fusion surgery or scoliosis surgery. Demographic information, perioperative visible blood loss volume, as well as laboratory results were recorded. The patients receiving fusion surgery or scoliosis surgery were further divided into the HBL positive subgroup and the HBL negative subgroup. Differences in the variables between the groups were then analyzed. Binary logistic regression analysis was performed to determine independent risk factors associated with HBL.Results For patients undergoing posterior spinal surgery, the independent risk factors associated with HBL were autologous transfusion(for fusion surgery P = 0.011, OR: 2.627, 95%CI: 1.574-2.782; for scoliosis surgery P < 0.001, OR: 2.268, 95%CI: 2.143-2.504) and allogeneic transfusion(for fusion surgery P < 0.001, OR: 6.487, 95%CI: 2.349-17.915; for scoliosis surgery P < 0.001, OR: 3.636, 95%CI: 2.389-5.231).Conclusion Intraoperative blood transfusion might be an early-warning indicator for perioperative HBL.展开更多

文摘目的探讨手术相关用血量大于等于20 U患者围术期血液管理特点。方法收集并分析北京协和医院2015年度用血量大于等于20 U手术患者的围术期资料,比较未经历非计划二次手术和经历非计划二次手术患者的相关信息。结果共36例患者纳入研究,经历非计划二次手术患者(n=12)初次择期手术中失血量明显低于未经历非计划二次手术患者(n=24),分别为1300和3000 ml(P<0.05);但非计划二次手术相较于其初次择期手术美国麻醉医师协会(American Society of Anaesthesiology,ASA)分级明显增高,Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ级分别为0、0、4、8、0例和2、9、1、0、0例;术中出血量(分别为2250和1050 ml)和输血量(红细胞分别为8和1 U,血浆分别为400和100 ml)亦均明显增加(P均<0.05)。36例患者中18例并发术前贫血。结论对于手术难度大、风险高的患者,在充分评估术中出血风险的基础上,采取个体化治疗方案,纠正术前贫血,术中严密止血,加强围术期凝血功能检测,可降低非计划二次手术的发生率,改善患者结局。
