概括

在极低妊娠年龄的新生儿中,带血红细胞输血可以减少早产严重的视网膜病变和支气管肺功能障碍. 需要进一步的研究来证实这些发现.

科学领域:

新生儿医学
血液学
儿童眼科医生

背景情况:

红细胞输血与早产儿视网膜病变 (ROP) 有关.
极低妊娠年龄的新生儿 (ELGAN) 特别容易发生输血相关的并发症.

研究的目的:

调查带血红细胞输血 (CB-RBC) 与ELGAN中的成人献血红细胞 (A-RBC) 相比,是否可以降低ROP的严重程度.
评估CB-RBC对该群体支气管肺功能障碍 (BPD) 的影响.

主要方法:

一个多中心随机试验 (BORN研究) 涉及8个意大利医院.
在经期29周+6周后,ELGAN被随机分配为接受A-RBC或CB-RBC.
主要结局是40周PMA后严重的ROP率或出院;次要结局包括BPD.

主要成果:

每个方案分析显示,CB- RBC组没有严重的ROP或需要治疗的ROP,而A- RBC组的ROP为34. 2% (P=0. 005).
中度/重度BPD发生在CB- RBC组的29. 4%,而A- RBC组的63. 2% (P=0. 039).
对治疗意向的分析显示,两组之间严重的ROP率没有显著差异.

结论:

在ELGAN中,CB- RBC输血可以提供对严重的ROP和BPD的保护.
每个协议的分析表明潜在的好处,但需要进一步调查.
这些发现强调了对脆弱的早产婴儿进行最佳输血策略的必要性.

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...
