[Prognosis factors in hypoxico-ischemic encephalopathy in full term infants]

This study analyzes 61 full-term neonates affected by hypoxic-ischemic encephalopathy, who were followed for a minimum of 15 months to determine the factors related to the later appearance of neurological sequels. No severe sequels have been detected, while 8.2% showed moderate sequels and 4.9% slight sequels. The degree of cerebral suffering and the intensity of convulsions influence both the appearance of sequels and their severity, contrary to the scores of the Apgar tests after one minute or 5 minutes and the birth weight. By applying the formula (Sequel Rate = 0.2143* Cerebral suffering + 0.3228* Convulsions - 0.2276* EEG RN - 0.0851), if the "sequel rate" is equal to or lower than 0.55, the probability of later sequels is null, whereas a value in excess of this figure indicates a 57.1% probability of their arising.
