概括
这次审查发现很少有证据表明,不同的输血策略显著影响创伤患者的死亡率或血栓塞栓事件. 需要进一步的研究来澄清主要出血管理的最佳方法.
科学领域:
- 创伤和紧急医疗医学
- 输血医学 输血医学
- 关键的护理关键的护理
背景情况:
- 创伤是全球死亡和残疾的主要原因.
- 早期识别和治疗出血和凝血病对于创伤患者的治疗结果至关重要.
- 缺乏对输血策略的共识,阻碍了临床实践的转化.
研究的目的:
- 评估成年创伤患者大出血后24小时内开始的输血策略的益处和危害.
- 综合来自各种血液产品输血协议的随机对照试验 (RCT) 的证据.
主要方法:
- 对18项涉及5041名参与者的RCT进行系统审查.
- 搜索了多个数据库 (CENTRAL,MEDLINE,Embase) 和试验登记册.
- 使用GRADE方法评估证据确定性.
主要成果:
- 医院前血输血对24小时死亡率有不确定的影响,但与标准护理相比,30天死亡率可能没有差异.
- 医院内策略,包括冷凝剂,固定比例组分疗法 (1:1:1 血:血小板:红血细胞) 和粘弹性静血分析 (VHA),与标准或常规测试相比,死亡率或血栓塞栓事件可能没有差异.
- 对全血输血和特定成分比率的证据 (例如,1:1:1对1:1:2) 给出了不确定的或低确定性死亡率和血栓塞栓事件的发现.
结论:
- 总的来说,有限的证据表明,在创伤患者的死亡率或血栓栓塞事件方面,各种输血策略之间几乎没有差异.
- 研究中的干预和比较器的异质性限制了数据的汇集.
- 需要进一步的研究,以建立最佳的输血协议,以治疗创伤严重出血.

Blood Transfusion and Agglutination
10.7K
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Blood Transfusion
457
Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Introduction to Hemostasis
4.8K
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...

Esophageal Varices-II: Clinical Features and Management
34
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Blood Pressure Imbalances and Circulatory Shock
728
Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

Extrinsic and Intrinsic Pathways of Hemostasis
4.6K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
