Cord blood being studied as a substitute for normal blood transfusions in the developing world. More research is necessary prior to the generalized utilization of cord blood transfusion. Cord blood Cord blood (umbilical cord blood) is blood that remains in the placenta and in the attached umbilical cord after childbirth. Cord blood is collected because it contains stem cells, which can be used to treat hematopoietic and genetic disorders. Cord blood is composed of all the elements found in whole blood - red blood cells, white blood cells, plasma, platelets. Compared to whole blood some differences in the blood composition exist, for
Percutaneous umbilical cord blood sampling levels and pH would aid in diagnosis of a condition, such as anemia, or delivery plan, if termination of the pregnancy is being considered or special plans must be made. Umbilical cord blood gas analysis may assist with clinical management and excludes the diagnosis of birth asphyxia in approximately 80% of depressed newborns at term. Severe fetal growth issues in conjunction with low oxygen in the fetus’ blood and high levels in the mother’s blood also indicate the use of PUBS. With more detailed observations and information on fetal tissue perfusion and metabolism, better predictions on development can be made.
