Summary of Guideline statements and recommendations.
指南声明和建议汇总
Initial patient evaluation and hemodynamic resuscitation
患者的初始评估和血流动力学复苏
1. ESGE recommends immediate assessment of hemodynamic status in patients who present with acute upper gastrointestinal hemorrhage (UGIH), with prompt intravascular volume replacement initially using crystalloid fluids if hemodynamic instability exists.
ESGE建议：立即评估急性上消化道出血（UGIH）患者的血流动力学状态，如果血流动力学不稳定，应首先使用晶体液及时补充血容量。
Strong recommendation, low quality evidence.
强推荐，证据质量较低。
Red blood cell (RBC) transfusion strategy
红细胞（RBC）输注策略
2. ESGE recommends, in hemodynamically stable patients with acute UGIH and no history of cardiovascular disease, a restrictive RBC transfusion strategy with a hemoglobin threshold of ≤ 7 g/dL prompting RBC transfusion. A post-transfusion target hemoglobin concentration of 7–9 g/dL is desired.
ESGE建议：对无心血管疾病史且血流动力学稳定的急性UGIH患者，采用限制性RBC输注策略，即血红蛋白阈值≤7 g/dL时，提示需要输注RBC。期望输血后达到目标血红蛋白浓度7-9 g/dL。
Strong recommendation, moderate quality evidence.
强推荐，证据质量中等。
3. ESGE recommends in hemodynamically stable patients with acute UGIH and a history of acute or chronic cardiovascular disease, a more liberal RBC transfusion strategy with a hemoglobin threshold of ≤ 8 g/dL prompting RBC transfusion. A post transfusion target hemoglobin concentration of ≥ 10 g/dL is desired.
ESGE建议：对有急性或慢性心血管疾病史且血流动力学稳定的急性UGIH患者，采用开放性RBC输注策略，即血红蛋白阈值≤8 g/dL时，提示需要输注RBC。期望输血后达到目标血红蛋白浓度≥10 g/dL。

强推荐，证据质量较低。
Patient risk stratification
患者风险分层
4. ESGE recommends in patients with acute UGIH the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Patients with GBS ≤ 1 are at very low risk of rebleeding, mortality within 30 days, or needing hospital-based intervention and can be safely managed as outpatients with outpatient endoscopy.
ESGE建议：在内镜管理前利用Glasgow-Blatchford评分（GBS）对急性UGIH患者进行风险分层。GBS≤1的患者再出血、30天内死亡或需要住院干预的风险极低，并可在门诊接受安全的门诊内镜管理。

强推荐，证据质量中等。
Management of antithrombotic agents (antiplatelet agents and anticoagulants)
抗血栓药物（抗血小板药物和抗凝剂）的管理
5. ESGE recommends that in patients with acute UGIH who are taking low dose aspirin as monotherapy for primary cardiovascular prophylaxis, aspirin should be temporarily interrupted. Aspirin can be re-started after careful re-evaluation of its clinical indication.

11. ESGE recommends that in patients with acute UGIH taking vitamin K antagonists (VKAs) who have hemodynamic instability, low dose vitamin K supplemented with intravenous prothrombin complex concentrate (PCC), or fresh frozen plasma (FFP) if PCC is not available, should be administered. However, this should not delay endoscopy or if required, endoscopic hemostasis.
ESGE建议：对于正在服用维生素K拮抗剂（VKA）且血流动力学不稳定的急性UGIH患者，应给予低剂量的维生素K并辅以静脉给予凝血酶原复合物（PCC）或新鲜冷冻血浆（FFP）（如果PCC不可用）。但是，这不应延迟内镜管理或必要的内镜止血。
Strong recommendation, low quality evidence.
强推荐，证据质量较低。
