  • Title: The clinical diagnosis of asphyxia responsible for brain damage in the human fetus.
    Author: Low JA, Simpson LL, Ramsey DA.
    Journal: Am J Obstet Gynecol; 1992 Jul; 167(1):11-5. PubMed ID: 1442908.
    Abstract:
    OBJECTIVE: Our objective was to review the clinical findings in infants who died in the perinatal period with brain damage attributable to asphyxia. STUDY DESIGN: The neuropathologic findings in 208 perinatal deaths have been reviewed. Thirty cases (22 fetal, eight newborn) had evidence of white matter or neuronal necrosis due to asphyxia. The clinical course of the pregnancy in 22 cases with brain damage attributable to fetal asphyxia were examined. RESULTS: The diagnosis of asphyxia was confounded by several factors: (1) asphyxia may occur at any time in the last half of pregnancy, (2) 50% of the antepartum asphyxia occurred when the pregnancy had no risk factors, (3) periodic fetal assessment in the complicated preterm pregnancies failed to identify the asphyxial episodes in the remaining cases of antepartum asphyxia, and (4) indicators of fetal asphyxia in the cases of intrapartum fetal asphyxia were obtained after the central nervous system injury had occurred. CONCLUSION: These findings highlight the difficulty in the diagnosis of fetal asphyxia at a stage that could permit intervention to prevent brain damage.
