新生儿肠道外营养相关性胆汁淤积的危险因素

Risk factors for parenteral nutrition-associated cholestasis in neonates

摘要:

肠道外营养（PN）是危重新生儿救治的重要支持、治疗手段，肠道外营养相关性胆汁淤积（PNAC）是其常见合并症。该文从非PN 营养成分及PN 营养成分相关角度综述新生儿PNAC 的危险因素。PNAC 危险因素主要包括早产、小于胎龄、延长的PN、疾病（主要是新生儿败血症及坏死性小肠结肠炎）、延迟喂养或低肠道内营养比例、持续PN 输注，以及氨基酸、脂肪乳种类/用量、能量供给量及部分微量元素含量等。

Abstract:

Parenteral nutrition (PN) is a life saving and support therapy for critical newborn infants. Parenteral nutrition-associated cholestasis (PNAC) is one of its common complications. This article focuses on the risk factors for PNAC in newborn infants in both non-nutrient and nutrient associated risk factors. The main risk factors include prematurity, small for gestational age, prolonged PN, diseases (especially sepsis and necrotizing enterocolitis), delayed or less proportional enteral nutrition, non cyclic PN, amino acids/lipids composition and dosage, energy supply and trace elements contents.
