Shenzhen Bao'an Maternal and Child Health Hospital146 enrolled

Overview

To study and analyze the association of the severity of anemia with neonatal morbidity and the risk factors of anemia in ealry life (less than 3 days of life) among the very low birth weight (VLBW) infants.

The rescue treatment of very low birth weight (VLBW) infants is the main task of our neonatal intensive care unit (NICU) is this era. Anemia of prematurity (AOP) is one of the most common complication of these infants, which can affect their growth, intelligence, behavior, immunity and hemodynamics, and even endanger their lives in severe situation. It is of great significance to investigate the association of the severity of anemia with neonatal morbidity and the risk factors of anemia in ealry life for improving the prognosis of these infants. Patient Registry procedures: First, the list of VLBW infants was obtained through medical record search, and sent to the principal investigator (PI) at each center when an infant was eligible for enrollment. Second, patients are included in this study according to the exclusion criteria by PI. Finally, the PI at each center will be responsible for the accuracy,completeness or representativeness of medical records, registry forms,data collection. Statistical analysis:The two groups were compared by a Χ2-test for categorical variables, Mann-Whitney U Test were used when reporting medians.A P value of \<0.05 was considered statistically significant.
