Methods A control trial was carried out in 60 Chinese neonates withsevere asphyxia. 30 neonates received loading dose of phenobarbital on an average of 5.6h of age. Results Themean value ol phenobarbital serum level obtained at the 4th day after birth was 21.9μg/ml. No significantdifference was observed in the two groups in terms of birth weight, gestational age, Apgar scores, sex, etc. Theimaging diagnosis within 3d of age in all subjects showed normal brain in 14, brain edema in 9 andintraventricular hemorrhage (IVH) in 7 in the treated group with a 53.3% of total complication rate, and normalbrain in 5, brain edema in 15, IVH in 9 and subarachnoid hemorrhage (SAH) in 1 in the untreated group with a83.3% of total complication rate. The incidence of intracranial damage in the untreated group was significantlyhigher than that in the treated group (83.3% vs 53.3%, P<0.05). In the treated group, 4 neonates with seizuresymptom were effectively controlled soon, and none of the other 26 developed seizure. The period of seizure in thetreated group was significantly shorter than that in the untreated group (P<0.05). Other clinical symptoms werealso sooner improved and no side effects were observed among the neonates treated with phenobarbital. Con-clusion The incidence of postasphyxiated intracranial damage was obviously decreased, and seizure could beprophylactically intervened by phenobarbital. It is recommended that early application of preventive phenobarbitalin severely asphyxiated neonates is reasonable in reducing the incidence of intracranial lesions and subsequentselzures.展开更多
