Study information

Scientific title

A randomised controlled clinical trial of the comparison of two techniques of umbilical cord blood collection (from mother versus on delivery table) on women with term pregnancy with low-risk vaginal delivery and a unique newborn


Study hypothesis

The collection of umbilical cord blood (UCB) clamped on the mother is more effective since it achieves a greater amount and cellularity of UCB units with no increase in cross-clamping time compared to clamping on the delivery table.

Ethics approval

Clinical Research Ethics Committee of Guipuzcoa Health Area approved on the 21st June 2010 (ref: 6/10)

Umbilical cord blood collection


Control group:
Clamping and cutting the umbilical cord blood on lower level about introitus, placing the newborn at delivery table (the table is about 80 cm from the introitus of the mother).

Experimental group:
Clamping and cutting the umbilical cord blood on upper level on the mother's abdomen.

Measured at collection after delivery; no follow up.

Intervention type



Not Applicable

Drug names

Primary outcome measures

Weight of cord blood units, quantitative variable, measured in mg. Outcomes will be measured simultaneously with the intervention.

Secondary outcome measures

Validity of the unit and storage. Validity criteria are considered:
1. If the count is 1.5 x 10^9 TNC unit is accepted
2. If the count is between 1.2 and 1.5 x 10^9, CNT is performed CD34 count, if this is greater than 4 x 10^6 units is accepted

Outcomes will be measured simultaneously with the intervention.
