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.

D005865 Gestational Age The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.

D000037 Abruptio Placentae Premature separation of the normally implanted PLACENTA from the UTERUS. Signs of varying degree of severity include UTERINE BLEEDING, uterine MUSCLE HYPERTONIA, and FETAL DISTRESS or FETAL DEATH.

D001034 Apgar Score A method, developed by Dr. Virginia Apgar, to evaluate a newborn's adjustment to extrauterine life. Five items - heart rate, respiratory effort, muscle tone, reflex irritability, and color - are evaluated 60 seconds after birth and again five minutes later on a scale from 0-2, 0 being the lowest, 2 being normal. The five numbers are added for the Apgar score. A score of 0-3 represents severe distress, 4-7 indicates moderate distress, and a score of 7-10 predicts an absence of difficulty in adjusting to extrauterine life. Score, Apgar
