研究目的: |
脐血采集作为新生儿筛查的重要手段,其对早产儿的正负面影响颇受关注。发达国家研究发现,过量脐血采集可增加早产儿病死率,且危险性与采血量正相关。但是我国目前还缺乏对极低出生体重儿采血量与预后的相关研究。本研究拟评估<=1500g早产儿是否采取脐血,对24小时、3天抽血量单位体重抽血量进行对比分析,亦包含对患儿的基本情况、对各系统的影响、体重增长率、住院天数等进行数据搜集。对体重进行分组,<1000g,<1250g,>=1250g三组数据进行输血情况的分析,为制定适合我国国情的ELBW早产儿脐血采集策略提供依据。本研究目标人群为<=1500g早产儿,旨在评估脐血采集对该人群的影响。 |

Objectives of Study: |
Umbilical cord blood collection, as an important method for newborn screening, has drawn significant attention regarding its positive and negative effects on premature infants. Research in developed countries has found that excessive umbilical cord blood collection can increase the mortality rate of premature infants, with the risk positively correlated with the volume of blood collected. However, there is currently a lack of studies in China regarding the relationship between the volume of blood collected from extremely low birth weight (ELBW) infants and their prognosis. This study aims to assess whether umbilical cord blood should be collected from premature infants weighing <=1500g, comparing blood collection volumes at 24 hours and 3 days per unit of body weight. It will also include data collection on the infants' basic conditions, impacts on various systems, weight gain rates, and length of hospital stay. The weight will be categorized into three groups: <1000g, <1250g, and >= 1250g, to analyze transfusion conditions. This study will provide a basis for developing umbilical cord blood collection strategies for ELBW premature infants that are suitable for China's context. The target population for this study is premature infants weighing <=1500g, aiming to evaluate the impact of umbilical cord blood collection on this group. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection will be conducted using Case Record Forms (CRFs) designed by the research team. These CRFs have been meticulously crafted to ensure the accurate and comprehensive collection of data relevant to the study's objectives. The data collected will include participants' basic information, clinical manifestations, treatment processes, and outcomes among other relevant details. Management of the research data will be performed electronically to ensure accuracy, integrity, and traceability.
