Patient blood management (PBM) strategies are needed in the neonate and paediatric population, given that haemoglobin thresholds used are often higher than recommended by evidence, with exposure of children to potential complications without meaningful benefit. A literature review was performed on the following topics: evidence-based transfusions of blood components and pharmaceutical agents. Other topics reviewed included perioperative coagulation assessment and perioperative PBM. The Transfusion and Anaemia Expertise Initiative (TAXI) consortium published a consensus statement addressing haemoglobin (Hb) transfusion threshold in multiple subsets of patients. A multicentre trial (PlaNeT-2) reported a higher risk of bleeding and death or serious new bleeding among infants who received platelet transfusion at a higher (50 000/μl) compared to a lower (25 000/μl) threshold. Recent data support the use of a restrictive transfusion threshold of 25 000/μl for prophylactic platelet transfusions in preterm neonates. The TAXI-CAB consortium mentioned that in critically ill paediatric patients undergoing invasive procedures outside of the operating room, platelet transfusion might be considered when the platelet count is less than or equal to 20 000/μl and there is no benefit of platelet transfusion when the platelet count is more than 50 000/μl. There are limited controlled studies in paediatric and neonatal population regarding plasma transfusion. Blood conservation strategies to minimise allogenic blood exposure are essential to positive patient outcomes neonatal and paediatric transfusion practices have changed significantly in recent years since randomised controlled trials were published to guide practice. Additional studies are needed in order to provide practice change recommendations.
鉴于血红蛋白阈值通常高于证据推荐值,新生儿和儿科人群需要采用患者血液管理(PBM)策略,使儿童面临潜在并发症的风险而无明显获益。对以下主题进行了文献回顾:血液成分和药物的基于证据的输血。回顾的其他主题包括围手术期凝血评估和围手术期 PBM。输血和贫血专业知识倡议(TAXI)联盟发布了一份共识声明,涉及多个患者亚组的血红蛋白(Hb)输血阈值。一项多中心试验(PlaNeT-2)报告称,与较低阈值(25,000/μl)相比,较高阈值(50,000/μl)输注血小板的婴儿出血和死亡或严重新出血风险更高。最近的数据支持将 25,000/μl 的限制性输血阈值用于预防早产儿预防性血小板输注。TAXI-CAB 联盟提到,在进行手术室外有创操作的危重症儿科患者中,当血小板计数小于或等于 20,000/μl 且血小板计数大于 50,000/μl 时无血小板输注益处时,可能考虑输注血小板。儿科和新生儿人群中关于血浆输注的对照研究有限。为了实现积极的患者结局,减少异体血液暴露的血液保护策略至关重要,近年来,由于随机对照试验的发表指导了实践,新生儿和儿科输血实践发生了重大变化。需要进一步的研究,以提供实践改变建议。
