2～3P%儿童有高热惊厥,长期的发作可有脑损害的危险,但抗惊厥的特续预防治疗尚无统一的意见,许多作者认为苯巴比妥能减少复发,但一些人仍有怀疑。在一次研究中,有人监测苯妥英钠的水平,认为复发惊厥的时间减少了而次数并不减少。本文对不同年龄绀的138例儿童进行了苯巴比妥、苯妥英钠和安慰剂的对照研究,以确定这些药物的药理学的效果。 2 ~ 3P% children have febrile seizures, long-term attacks may have the risk of brain damage, but there is no unified opinion on the special treatment of anticonvulsant, many authors believe that phenobarbital can reduce the recurrence, but some people still have doubts . In one study, someone was monitoring the level of phenytoin, reducing the time it took to recurrent seizures and not decreasing it. A controlled study of phenobarbital, phenytoin, and placebo was performed in 138 children of various ages of cyanosis to determine the pharmacological effects of these drugs.
