AB  - OBJECTIVE: To examine the effect of intertwin interval on umbilical cord pH and
      Apgar scores of the second twin after vaginal delivery. METHODS: A retrospective 
      study of twin deliveries at a university hospital in Spain between August 2012
      and September 2017. Inclusion criteria were vaginal delivery of both twins at 32 
      gestational weeks or more. Exclusion criteria were monochorionic pregnancies and 
      indication for cesarean delivery. The sample was dichotomized by intertwin
      interval (<10 and >/=10 minutes). Neonatal outcomes including Apgar scores and
      umbilical cord pH were evaluated. RESULTS: Overall, 323 twin deliveries were
      included. Intertwin interval was less than 10 minutes in 277 (85.6%) cases, and
      10 minutes or longer in 46 (14.2%). There were no differences in maternal or
      obstetric characteristics between the groups. Incidence of instrumental delivery 
      (P<0.001) and internal podalic version (P<0.001) for the second twin was higher
      in the longer interval group. A longer interval was associated with higher
      frequencies of 1-minute Apgar score below 4 (P=0.009), 5-minute Apgar score below
      7 (P<0.001), and umbilical cord pH below 7.15 (P<0.001). CONCLUSION: Second twins
      with an intertwin interval of 10 minutes or longer are more likely to have poorer
      Apgar scores and arterial blood pH below 7.15.
