[Hypoxic-ischemic encephalopathy of the full term newborn. Contribution of the electroencephalogram and trans-fontanelle echography to the prognostic evaluation. Report of 29 cases]. / Encéphalopathie anoxo-ischémique du nouveau-né à terme. Apport de l'électroencéphalogramme et de l'échographie transfontanellaire à l'évaluation pronostique. A propos de 29 observations.

This study was aimed at assessing by EEG recording and cranial imaging the cerebral function of 29 full term newborns presenting with hypoxic-ischemic encephalopathy and at establishing a correlation between the results and the neurological outcome. A correlation between the Sarnar's classification and the neurological outcome was observed, except for the intermediate grade. In this case, impairment of the EEG was variable and neurological prognosis was sometimes evidenced by cranial imaging. Unfavorable neurological outcome occurred when thalamic lesions were present, independently of clinical signs and EEG abnormalities.
