  Purpose

To compare the evolution of the infant's weight before delayed cord clamping (2 minutes after birth) as an indirect measure of the volume of placental transfusion in a group of healthy and fullterm newborns, placed at the level of the introitus versus another group placed on the abdomen of the mother.

Primary Outcome Measures:
  • Compare infant's birth weight before delayed cord clamping as an indirect measure of the volume of placental transfusion in a group of healthy fullterm newborns placed at the level of the introitus versus at the the mother's abdomen. [ Time Frame: inmediately after birth until 2 minutes after birth ] [ Designated as safety issue: No ]

    Every elegible and randomiced newborn will be Immediately after birth placed on a scale at the level of the introitus, and the infant's weight will be recorded at 10± 2 sec.

    Group 1: The infant will be held by the neonatologist at introitus level. The cord will be clamped at 120 seconds after birth.

    Group 2: The newborn will be placed on the abdomen of the mother immediately after the first weight measurement. The cord will be clamped at 120 seconds after birth.

    Both groups will be weigth after the cord clamping.



Secondary Outcome Measures:
  • To compare venous peripherical hematocrit and bilirubin values between the 2 groups . [ Time Frame: 36-48 hs ] [ Designated as safety issue: Yes ]
    venous hematocrit and bilirubin will be taken together with the sample taken for the mandatory neonatal screening.

Arms Assigned Interventions
Active Comparator: Position at introitus level
The newborn will be held by the neonatologist at the level of the introitus, the cord will be clamped at 2 minutes after birth with a plastic clamp placed at 1 cm from its cutaneous insertion.
Other: Position at introitus level
After birth: Weight at 10 + 2 sec then Held the baby at the level of introitus and Cord clamping will be performed at 120 sec Weight after clamping
Experimental: position at Maternal Abdomen
The newborn will be placed on the abdomen and of the mother immediately after the first weight measurement. The cord will be clamped at 2 minutes after birth .
Other: Position at Maternal Abdomen
Newborns weight's difference between having them weighed immediately after birth and when cord is clamped in both positions(introitus and abdomen).

Detailed Description:

Pilot study. Randomized controlled trial not blind, in one center. Informed consent will be obtained during pregnancy or admittance and previous to birth.

Hypothesis: Placing the infant on the maternal abdomen without cord clamping during the first 2 minutes after birth does not change significantly the transfusion volume as compared to infants whose cord is clamped after 2 minutes but who are placed at the level of the introitus

Term newborns by vaginal delivery and without complications with cord clamping at 2 minutes after birth. Weight differences will be evaluated when positioning the infant at the level of the introitus or on the maternal abdominal-thoracic level (at or over placental level).

Study subjects will be assigned to two groups, both with delayed clamping,according to a sequence of random numbers generated by computer. The assignment will be done through opaque, sealed, easy opening envelopes, opening the envelope at the moment the mother enters the delivery room. Both parents and obstetric group will be then informed about which group the infant will be assigned to.

In both groups: The newborn will be immediately placed on a scale, previously set at the level of the maternal introitus to record his/her weight.

Group 1: Clamping at level of introitus: The infant will be held by the neonatologist at introitus level,immediately after the initial weight Group 2: Clamping on Maternal Abdomen: The newborn will be placed on the abdomen of the mother immediately after the first weight measurement.

In both groups:A plastic clamp will be put at approximately 1cm from the cutaneous insertion of the umbilical cord at 120 seconds after birth and then a new Weight will be obteined after clamping.
