From January 1989 to June 1990, 13 institutions in our country studied jointly the application of a 20-item neonatal behavioral neurological assessment (NBNA) in asphyxiated babies. Of 145 cases, 125 were followed up to 1-2 years of age. The results showed that in predicting prognosis, the sensitivity and specificity of NBNA score at 7 days after birth were 88.9% and 82.6% and 12-14 days, 84.6% and 97.4% respectively. Its value in predicting prognosis is superior to Sarnat degree, cranial CT and B ultrasound. This method is practical, economical and reliable. It is worth popularizing.
