A study of 199 pairs of twins evaluated the effect of delivery interval on
the outcome of the second twin. All twins in the study weighed greater than
1,500 grams and were at or beyond 34 weeks gestation, and the first twin
was delivered vaginally. Neonatal data evaluated included the five-minute
Apgar score and evidence of birth trauma.
Time intervals between the births of each twin were divided into four
categories: 15 or less minutes, 16 to 30 minutes, 31 to 60 minutes, and
greater than 60 minutes. An interval of greater than 60 minutes between
twin deliveries did not have an adverse effect on outcome, as judged by
Apgar score, length of stay in the hospital, or birth trauma.
Researchers concluded that a prolonged delivery interval between twins did
not have an adverse effect on the outcome of the second twin.
