摘要:

新生儿坏死性小肠结肠炎(NEC)是一种新生儿时期严重威胁生命的胃肠道疾病,多以腹胀、呕吐、血便及休克等非特异性症状为主要临床表现,在早产儿中症状更不典型。目前广泛被认可的NEC病因包括早产、感染、缺氧缺血和喂养不当等。近年来,红细胞输注(RBCT)与NEC之间的相关性受到广泛关注。文章通过梳理输血与NEC的相关性、输血相关性坏死性小肠结肠炎(TANEC)的影响因素及发病机制和TANEC的预防等方面的研究进展,认为TANEC是客观存在的,但贫血本身才是TANEC的发病基础,预防贫血、合理输血是减少TANEC的基本 策略。

Abstract:

Neonatal necrotizing enterocolitis (NEC) is a serious and life-threatening gastrointestinal disease in the neonatal period. The atypical clinical manifestations of NEC, especially in premature infants, are abdominal distension, vomiting, bloody stools and shock. At present, the widely known pathogenesis of NEC includes preterm birth, infection, hypoxia-ischemia and improper feeding, etc. In recent years, the association between red blood cell transfusion (RBCT) and NEC was widely concerned. This article reviewed the relationship between RBCT and NEC, the influence factors, possible pathologic mechanism and the prevention strategies of transfusion-associated necrotizing enterocolitis (TANEC). Based on the available evidences, the author believes that TANEC is a clinical condition. However, anemia is the basis for the onset of TANEC. Prevention of anemia and reasonable blood transfusion are the basic strategies to reduce TANEC.
