概括

血小板造影 (TEG) 使用降低了血输血,但增加了血浪费. 红细胞 (RBC) 的使用和浪费发生了变化,尽管注意到COVID-19大流行的影响.

科学领域:

输血医学输血医学
实验室医学实验室医学
手术服务手术服务.

背景情况:

血栓形成显微镜 (TEG) 是用于实时凝血监测的粘弹性测试平台.
评估TEG对血液产品利用和浪费的影响对于优化输血实践至关重要.

研究的目的:

在实施TEG后,评估血液成分使用和浪费的变化.
分析大规模输血协议 (MTP) 血液利用和TEG后回报的变化.

主要方法:

在TEG实施前和之后的104周内,对血液成分输血和废物的回顾性分析.
血液利用和浪费的比较使用配对的t测试.
通过独立的t测试对160个案例 (80个TEG前,80个TEG后) 的MTP利用率和回报率进行分析.

主要成果:

血输血减少了26% (P < 0.05),而红细胞输血增加了15% (P < 0.01).
平均红细胞废弃物减少 (P < 0.01),但平均血废弃物显著增加 (P < 0.001).
没有观察到血小板,冷沉积物或MTP利用率和回报率的显著变化.

结论:

血利用率在TEG后降低,与文献一致.
血废物的意外增加可能来自增加的,未输血的订单.
红细胞利用和浪费显示出显著的变化,COVID-19大流行是潜在的混因素.

Venous Thrombosis IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration.
