To determine the effect of a standardized tranexamic acid (TXA) protocol on red blood cell transfusions and adverse events in fragility hip fracture patients.
Retrospective cohort study.
Academic Tertiary Care Center.
PATIENTS/PARTICIPANTS: Series of 209 patients with fragility hip fractures treated operatively from April 1, 2019 to September 30, 2019.
Eligible patients received 4 intravenous doses of TXA. Some patients missed doses and only received between 1 and 3 doses of TXA: Ineligible patients received no TXA. Patients with medical conditions precluding the use of TXA were deemed ineligible: allergy to TXA; creatinine clearance <30 mL/min; active malignancy; vascular event in the past year; anticoagulant use; fracture > 48 hours prior to presentation.
Red blood cell transfusion; major adverse vascular events; minor drug related adverse events.
Patients who received all 4 doses of TXA (n = 70) had a significantly lower transfusion rate compared to those who did not receive any TXA (7.1% vs 28.1%, = .003). There were no significant differences in the number of major or minor adverse events between the 2 groups.
The use of a standardized TXA protocol of 4 doses significantly decreases transfusion rates in eligible patients undergoing operative intervention for fragility hip fracture without an increase in major or minor adverse events. These findings are even more pronounced in patients with decreased preoperative hemoglobin. Prognostic Level III.
确定标准化氨甲环酸(TXA)方案对脆性髋部骨折患者红细胞输注及不良事件的影响。
回顾性队列研究。
学术性三级医疗中心。
患者/参与者:2019年4月1日至2019年9月30日接受手术治疗的209例脆性髋部骨折患者。
符合条件的患者接受4剂静脉注射TXA。部分患者漏服剂量,仅接受了1至3剂TXA;不符合条件的患者未接受TXA。因医疗状况而不能使用TXA的患者被视为不符合条件:对TXA过敏;肌酐清除率<30 mL/分钟;活动性恶性肿瘤;过去一年内发生血管事件;使用抗凝剂;就诊前骨折>48小时。
红细胞输注;主要不良血管事件;轻微药物相关不良事件。
接受全部4剂TXA的患者(n = 70)与未接受任何TXA的患者相比输血率显著降低(7.1%对28.1%,P = 0.003)。两组之间主要或轻微不良事件的数量无显著差异。
使用4剂标准化TXA方案可显著降低接受脆性髋部骨折手术干预的符合条件患者的输血率,且不增加主要或轻微不良事件。这些发现在术前血红蛋白降低的患者中更为明显。预后水平III。
