The acute systemic complications of perinatal asphyxia, defined as an umbilical artery pH at birth of 7.10 or less, were evaluated in fifty full-term newborn infants. We also investigated the prenatal complications that lead to asphyxia, and the relationship between Apgar score and cord pH. Asphyxia or fetal distress was not identified in 56% of the cases. The most common condition associated with asphyxia was prolonged labor followed by abruptio placentae. About half of the babies studied, suffered some degree of renal and brain dysfunction; 24% had severe respiratory disease. Myocardial failure was present in 24%. Regarding metabolic complications, the most frequent was hypocalcemia, present in 44%. On the other hand, there was no correlation between Apgar score and cord pH. Mortality was 22%. The main cause of death was Persistent Pulmonary Hypertension.
