The study aimed at comparing restrictive and liberal transfusion strategy in reducing mortality in patients with upper gastrointestinal bleeding (UGIB).
This was a single-center, prospective, open-label, non-inferiority, randomized controlled trial conducted over two years. Patients presenting with UGIB were randomized into restrictive (hemoglobin (Hb) <7 g/dl) or liberal (Hb <8 g/dl) transfusion strategy groups. Transfusion was given till patients achieved target Hb of 9 g/dl in restrictive and 10 g/dl in the liberal arms. Patients with exsanguinating bleeding, transfusion within 90 days, recent history of trauma or surgery were excluded. Primary outcome was mortality rate and the secondary outcomes were morbidity, re-bleeding episodes and the need for intervention.
A total of 224 patients were randomized to 112 patients in each group. Demographic characteristics were comparable. 45-day mortality was similar between the two groups (restrictive vs. liberal; 10/112 vs. 12/112; P = 0.65). The number of in-hospital bleeding episodes (12 vs. 9; P = 0.25), incidence of re-bleeding during the 45-day follow-up (13 vs. 14; P = 0.84), need for endoscopic banding for varices (37/112 vs. 39/112, P = 0.99), mean hospital stay (days) (3.21 ± 2.78 vs. 2.73 ± 1.29; P = 0.10) were similar between the two groups.
Restrictive transfusion strategy is non-inferior to liberal transfusion strategy in patients with UGIB.
本研究旨在比较限制输血和自由输血策略在降低上消化道出血(UGIB)患者死亡率方面的效果。
这是一项为期两年的单中心、前瞻性、开放性、非劣效性、随机对照试验。将出现 UGIB 的患者随机分为限制输血(血红蛋白(Hb)<7 g/dl)或自由输血(Hb<8 g/dl)策略组。在限制输血组中,输血直至患者达到目标 Hb 9 g/dl,在自由输血组中,输血直至患者达到目标 Hb 10 g/dl。排除失血性出血、输血在 90 天内、近期有创伤或手术史的患者。主要结局是死亡率,次要结局是发病率、再出血发作和需要干预的情况。
共有 224 名患者随机分为两组,每组 112 名。两组的人口统计学特征相似。两组的 45 天死亡率相似(限制输血组 vs. 自由输血组;10/112 与 12/112;P=0.65)。住院期间出血发作次数(12 次与 9 次;P=0.25)、45 天随访期间再出血的发生率(13 次与 14 次;P=0.84)、需要内镜套扎治疗静脉曲张的次数(37/112 与 39/112;P=0.99)、平均住院时间(天)(3.21±2.78 与 2.73±1.29;P=0.10)在两组间相似。
在 UGIB 患者中,限制输血策略与自由输血策略相比不劣效。
