概括

输血,包括红细胞 (RBC),新鲜冷血 (FFP) 和血小板缩物 (PC),在体外膜氧化 (ECMO) 患者中与更高的90天死亡率有关. 优化输血策略对于改善结果至关重要.

科学领域:

关键护理医学关键护理医学
血液学血液学血液学
输血医学输血医学

背景情况:

在接受体外膜氧化 (ECMO) 的患者中,输血很常见.
输血量对ECMO患者结局的影响尚未完全理解.
之前的研究还没有确定输血与这种脆弱人群的死亡率之间的关系.

研究的目的:

调查ECMO患者的血液产品输血量与90天死亡率之间的联系.
为了确定预测ECMO患者死亡率的关键输血变量.
为优化ECMO护理中的输血实践提供证据.

主要方法:

利用一个大型的行政数据库 (韩国国家医疗保险服务,2014-2020年) 来识别ECMO病例.
不包括19岁以下或ECMO持续时间小于1天的患者.
分析红细胞 (RBC),新鲜冷血 (FFP) 和血小板度 (PC) 经住院正常化,使用多变量逻辑回归和机器学习模型 (Random Forest,XGBoost) 评估90天死亡率.

主要成果:

总共有11,874名ECMO患者被纳入;58.8%的人经历了90天死亡率.
较高的输血量 (正常范围的50-100%) 对于红细胞,FPF和PC显着与90天死亡率的增加有关.
通过机器学习模型,通过住院正常化的红血细胞,FP和PC输血被确定为死亡率的首要预测因素.

结论:

输血,特别是通过住院正常化的较高体积,是ECMO患者90天死亡率的关键预测指标.
优化输血管理对于改善ECMO患者的生存和安全至关重要.
对输血值和针对ECMO患者量身定制的策略进行进一步研究是有必要的.

Blood Transfusion and Agglutination

Blood Transfusion and Agglutination

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

Blood Transfusion

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...

Oxygen Transport in the Blood

Oxygen Transport in the Blood

Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...
