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.
对50名足月新生儿评估了围产期窒息的急性全身并发症，围产期窒息定义为出生时脐动脉pH值为7.10或更低。我们还调查了导致窒息的产前并发症，以及阿氏评分与脐带血pH值之间的关系。56%的病例未发现窒息或胎儿窘迫。与窒息相关最常见的情况是产程延长，其次是胎盘早剥。约一半接受研究的婴儿出现某种程度的肾和脑功能障碍；24%有严重呼吸系统疾病。24%存在心肌衰竭。关于代谢并发症，最常见的是低钙血症，发生率为44%。另一方面，阿氏评分与脐带血pH值之间无相关性。死亡率为22%。主要死亡原因是持续性肺动脉高压。
