研究目的: |
1.系统描述我国不同地区早产儿出院时的铁稳态,包括不同胎龄及不同出生体重的铁稳态,分析影响因素。 2.收集我国早产儿孕母疾病和铁补充及早产儿延迟脐带结扎/脐带挤压、住院期间医源性失血、铁补充、输血、促红细胞生成素的使用和生长速率等临床资料,分析不同情况对铁稳态的影响。 3.识别影响早产儿出院时ID与铁超载的影响因素,建立风险评估模型,明确高危人群,为早产儿出院时精准补铁提供依据。 4.重点分析不同输血阈值及累积输血量与出院时铁稳态的关系 5.探讨早产儿铁稳态与早期合并症(如BPD、NEC、EOS/LOS、IVH、ROP等)的交互作用,通过中介效应分析与亚组分层,明确不同合并症状态下的铁代谢特征,解析铁缺乏/超载与早产儿不良结局的双向关系。 |

Objectives of Study: |
1. Systematically describe the iron homeostasis of preterm infants at the time of discharge in different regions of China, including the iron homeostasis of different gestational ages and different birth weights, and analyze the influencing factors. 2. Collect clinical data of diseases of pregnant mothers of preterm infants in China, iron supplementation, delayed cord clamping/cord milking of preterm infants, iatrogenic blood loss during hospitalization, iron supplementation, blood transfusion, use of erythropoietin, and growth rate, etc., and analyze the impact of different situations on iron homeostasis. 3. Identify the influencing factors of iron deficiency (ID) and iron overload in preterm infants at the time of discharge, establish a risk assessment model, clarify the high-risk population, and provide a basis for precise iron supplementation in preterm infants at the time of discharge. 4. Focus on analyzing the relationship between different blood transfusion thresholds, cumulative blood transfusion volume, and iron homeostasis at the time of discharge. 5. Explore the interaction between iron homeostasis in preterm infants and early complications (such as bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), early-onset sepsis/late-onset sepsis (EOS/LOS), intraventricular hemorrhage (IVH), retinopathy of prematurity (ROP), etc.). Through mediation effect analysis and subgroup stratification, clarify the characteristics of iron metabolism under different complication statuses, and analyze the bidirectional relationship between iron deficiency/overload and adverse outcomes of preterm infants. |
