小儿烧伤惊厥病因及发病机制的研究现状

小儿烧伤惊厥是烧伤早期的严重并发症之一，临床上发生率较高，据统计其发病率国外报道为6．6％，国内为5．4％。原因是多方面的，其中高热、低血容量性休克、电解质紊乱、酸碱平衡失调、烧伤脑病以及消化道应激性溃疡出血等是小儿烧伤惊厥的常见病因，其机制尚未明了，一般认为大脑神经元异常放电所致。本文综述了近十年来有关小儿烧伤惊厥的病因及其机制。

Present status of the research on the causes and mechanism of pediatric burn convulsion

Convulsion is a serious complication with high incidence in burned children at the early stage. In foreign countries, it was reported to have an incidence of 6.6% and in our country 5.4%. High fever, hypovolemic shock, electrolyte disorder, acid- base imbalance, burn encephalopathy and digestive tract stress ulcer and bleeding are common causes of convulsion. The mechanism of its pathogenesis is still not clear. Abnormal electric discharge of cerebral neuron may be one of the main causes. This paper makes a review of the research progress in past 10 years.
