Objective

To evaluate the factors influencing twin-to-twin delivery time interval and the short-term outcome of the second twin.

Material and methods

We performed a retrospective, descriptive study by reviewing a computerized database and the medical records of pregnant women attending the Miguel Servet University Hospital from January 2005 to December 2007. A statistical analysis was performed to determine the factors potentially affecting twin-to-twin delivery time interval, including maternal characteristics, gestational age, mode of delivery, fetal weight discordance, umbilical artery pH and Apgar score.

Results

Of the 13,430 deliveries registered during the study period, 206 twin pregnancies met the inclusion criteria. Most (79.6%) of the second twins were born within 5 min of delivery of the first twin. Maternal characteristics such as age, parity, obesity and smoking were not related to twin-to-twin delivery time interval. A longer time interval was associated with an increased risk of low Apgar scores and a decline in umbilical artery pH in the second twin. Vaginal operative delivery was associated with an increased time interval.

Conclusion

Based on our data and the results of previous studies, twin-to-twin delivery time interval seems to be an independent risk factor for adverse neonatal outcome.
