Summary
The second born twin faces no increased risk of complications compared to the first born twin. Delivery method does not impact twin perinatal outcomes, even for low birth weight infants.
Area of Science:
- Obstetrics and Gynecology
- Perinatology
- Neonatal Research
Background:
- The birth order of twins may influence perinatal outcomes.
- Previous studies have yielded conflicting results regarding risks associated with being the second-born twin.
Purpose of the Study:
- To compare the perinatal outcomes of first-born versus second-born twins.
- To investigate if the delivery mode affects twin outcomes.
- To identify specific risk factors for adverse outcomes in twins.
Main Methods:
- Retrospective review of twin deliveries between April 1994 and April 1996.
- Exclusion criteria included twins weighing less than 500g, lethal malformations, or pre-labor fetal demise.
- Comparison of perinatal mortality and 5-minute Apgar scores between first and second-born twins.
Main Results:
- Perinatal mortality rates were similar for both first and second-born twins.
- Five-minute Apgar scores were comparable between the two birth positions.
- Twins weighing less than 1500g were identified as a high-risk group.
- The mode of delivery did not demonstrate an influence on perinatal outcomes for either twin.
Conclusions:
- The second-born twin does not appear to be at a significantly increased risk of complications compared to the first-born twin.
- Cesarean delivery does not offer improved perinatal outcomes for twins based on birth order.
- Special attention and management strategies may be warranted for twins with birth weights under 1500g.
