[Analysis of factors influencing the cord blood sample collection for clinical purposes].
The survival rate of patients after cord blood transplantation depends on the number of nucleated cell transplants. The number of nucleated cells available for transplantation closely correlates with collected volume of cord blood. The influence of several obstetric factors on the volume of cord blood donation was investigated. Cord blood was obtained from 32 normal full-term deliveries. Length of gestation, age of mother, weight of placenta and length of umbilical cord were analysed for their impact on the volume of cord blood. Mean volume of collected cord blood was 103 ml. We did not establish the correlation between the volume of collection and the weight of placenta (measured after blood collection), the length of gestation and the age of mothers. A close and significant correlation (p < 0.05, r = 0.78) concerned the length of umbilical cord and the volume of cord blood donation. Length of umbilical cord is the parameter which may be useful for selection of the most promising cases in the collection of cord blood.
