儿童的血小板输血实践,特别是关于病原体减少 (PR) 和血小板添加剂溶液 (PAS) 的做法,会影响血小板计数和输血负担. 这些因素没有影响住院或死亡率.
科学领域:
- 儿科血液学 儿科血液学
- 输血医学 输血医学
- 临床流行病学临床流行病学
背景情况:
- 血小板输血对于新生儿和有出血风险的儿童至关重要.
- 了解影响输血有效性和负担的因素对于优化儿科护理至关重要.
研究的目的:
- 分析小儿病患者血小板输血的流行病学.
- 确定供体和血小板特征和输血后结果之间的关联,包括血小板增加和输血负担.
主要方法:
- 一个回顾性,多中心的队列研究,利用捐赠者-组件-接受者链接的数据库.
- 包括从2019年4月至2023年6月18岁以下的患者.
- 分析了血小板输血频率,剂量,输血前计数以及与产品特征 (例如,病原体减少,添加剂溶液,储存时间) 和供体因素 (性别,年龄) 的关联的数据.
主要成果:
- 在3.6%的住院患者中进行了血小板输血,根据年龄组有所不同.
- 病原体减少 (PR),血小板添加剂溶液 (PAS),较长的存储时间 (>3天),男性捐赠者和较老的捐赠者年龄 (>40岁) 与较低的输血后血小板增加有关.
- 使用PR,PAS,更长的存储时间和更老的供体年龄与随后输血的更高率相关,但与住院时间或死亡率无关.
结论:
- 大多数儿科输血,不包括那些活跃出血,发生在高的输血前血小板计数.
- 特定的输血成分和供体特征会影响儿童的血小板增加和输血负担.
- 研究结果表明,在儿科患者群体中优化输血策略的领域,需要进一步的潜在验证.

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...
Blood Transfusion and Agglutination
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...
Predicting Reaction Outcomes
Outcomes of Glycolysis
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
