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. The range of
delivery interval was two minutes to 866 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. -MIDIRS, June 1996
