title: Outcomes of twin gestations at the University of Colorado Health Sciences Center, 1973-1983.
abstract: A retrospective study was undertaken of 341 twin pregnancies over a ten-year period at the University of Colorado Health Sciences Center. The perinatal morbidity and mortality were higher than for singleton gestations, but no difference was found between the first and second twins. Bed rest was effective in prolonging gestation and decreasing perinatal mortality (P less than .05). Delivery of the second twin in noncephalic presentation was accomplished vaginally in 46.5%, with external version successful in five of six attempts. The interval between the birth of each twin did not affect outcome.
