HIE, hypoxia, death
HYPOXIA, HYPOXIC ISCHEMIC ENCEPHALOPATHY
Most neonates actively experience breathing air after birth; however, 10% require active resuscitation for active breathing and 1% require extensive care. The inability of neonates to breathe results in hypoxia. If timely treatment is not provided, hypoxia could lead to hypoxic ischemic encephalopathy (HIE) or neonatal death.UCB is rich in various stem cells and nutrients, including hematopoietic stem cells, mesenchymal stem cells, endothelial progenitor cells, unrestricted somatic cells, and very small embryonic/ectoderm-like stem cells.We hypothesized that umbilical vein blood could be used for both blood gas analysis and hematopoietic stem cell preparation This study is the first to investigate the feasibility of umbilical vein blood collection for both blood gas analysis and preparation of umbilical blood hematopoietic stem cells. Providing a new feasible scheme for collecting cord blood for blood gas analysis without affecting the indices related to cord blood hematopoietic stem cell transplantation.
