概括

免疫性血小板缺血 (ITP) 中的临界出血很少见,但致命,特别是在脑内出血的老年人中. 延迟治疗在这些严重的血液学紧急情况中显著增加死亡风险.

科学领域:

血液学血液学血液学
紧急医疗紧急医疗
临床研究临床研究

背景情况:

免疫性血栓缩 (ITP) 可以导致危及生命的严重出血事件.
了解 ITP 中关键出血的特征和结果对于及时管理至关重要.

研究的目的:

确定患有ITP的成人和儿科患者中严重出血的频率,管理策略和结果.
确定与ITP关键出血相关的风险因素和治疗模式.

主要方法:

在美国和加拿大的7个中心 (2010-2019) 进行了回顾性队列研究.
包括ITP和血小板数<20 x10 ^ 9 / L的患者到急诊室.
分析了人口统计,出血特征,干预措施,治疗时间和死亡率的数据.

主要成果:

在1226名ITP患者中,有2.3%患有严重出血;80%的成人和46.2%的儿童患有内出血 (ICH).
常见的治疗方法包括血小板输血,皮质类固醇和静脉注射免疫球蛋白 (IVIG).
总的来说,死亡率为32.1%,在成年人中 (46.7%) 比儿童 (15.4%) 高,治疗延迟和ICH是重要的因素.

结论:

在ITP中,临界出血很少发生,但与高死亡率有关,特别是在患有ICH的老年人中.
及时治疗至关重要,因为延迟与较差的结果相关.
进一步研究优化关键ITP出血的管理策略是有必要的.

Disorders of Hemostasis

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

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...
