Biochemical differences related to birth order in triplets.

Summary
Biochemical parameters in triplets were analyzed, finding no significant differences in acidosis or hypoxia based on birth order. This suggests prolonged gestation in utero for later-born triplets does not negatively impact their health without complications.
Area of Science:
- Neonatal physiology
- Perinatal biochemistry
- Multiple gestations
Background:
- Limited data exists on biochemical parameters in triplet neonates.
- Understanding fetal well-being in multiple births is crucial for neonatal care.
Purpose of the Study:
- To investigate umbilical cord blood biochemical parameters in triplets.
- To assess the impact of birth order on neonatal outcomes in triplets.
Main Methods:
- Umbilical artery and venous blood samples were collected from seven sets of triplets (21 infants).
- Measured parameters included pH, PO2, PCO2, lactate, and base deficit.
- Compared outcomes with birth weight, Apgar scores, and delivery route.
Main Results:
- No significant differences were found in biochemical parameters, birth weight, or Apgar scores related to birth order.
- Acidosis or significant base deficit was not observed in the third triplet compared to the first two.
- All triplets were delivered via the same route (6 cesarean, 1 vaginal).
Conclusions:
- Prolonged in utero duration after the first triplet's delivery does not appear to cause metabolic acidosis or hypoxia.
- Neonatal outcomes in triplets are not significantly affected by birth order in the absence of obstetric complications.
