The disadvantages of the second twin in respect of his birth conditions are of great concern. In this study we have reviewed 90 twin births occurred at the Maternidade da Encruzilhada (CISAM) in Recife, from January/92 to December/93, in order to compare perinatal variables between the first and second twin. Fetal presentation, way of delivery, birth weight, Apgar of the 1st and 5th minutes, occurrence of perinatal complications such as hyaline membrane syndrome, transitory tachypnea, and neonatal infection and, finally, the prognosis of each of the twins were evaluated. There was no statistical difference between the incidence of non-vertex presentation, cesarean section, low birth weight, Apgar < 7 in the 1st and 5th minutes and neonatal complication cited above. There was also no difference in perinatal mortality between the first and the second twin. Our results suggest a similar birth condition for both twins of a same pregnancy, therefore, the same perinatal care must be provided for each one.
