Conclusions
Delivery route and birth weight influence the volume of cord blood and the total nucleated cell count. Gestational age influences only the volume of cord blood.
Results
Most donations came from women with ages between 18 and 29 years (62.8%), gestational age≥40 weeks (55.2%), vaginal delivery (51.3%), primiparous (41.4%), and with male newborns (54.4%) weighing between 3000 and 3499g (41.8%). The volume of the donations ranged from 71.6 to 275.2mL, the total nucleated cell count ranged from 4.77×10(8) to 31.0×10(8) cells and CD34(+) cells ranged from 0.05 to 1.23%. There were statistically significant differences in the volume with respect to gestation age>38 weeks (p-value=0.001), cesarean section (p-value<0.001) and birth weight>3500g (p-value<0.001). The total nucleated cell count was positively affected by cesarean section (p-value=0.022) and birth weight>3500g (p-value<0.001). There was no statistically significant difference between the variables and the percentage of CD34(+) cells. Conclusions: Delivery route and birth weight influence the volume of cord blood and the total nucleated cell count. Gestational age influences only the volume of cord blood.
