目的 探讨小儿外伤后急性弥漫性脑肿胀(PADBS)的诊断和高压氧(HBO)治疗机制。方法 回顾性分析21例患儿的临床表现、CT影像和HBO疗效。结果 本组19例采用HBO均治愈,单纯药物治疗死亡1例,减压手术死亡1例。结论 小儿PADBS临床表现无特征。CT是首选检查方法,多表现为弥漫性脑肿胀,出现早,脑CT值常增高。HBO对本症治疗有效,可能与HBO在收缩脑血管、减少脑血流同时,能增加脑千血流和氧供有关。尤其对单纯性脑肿胀且GCS8分以上患儿效果好,可做为HBO治疗指征早期进行。
Objective To investigate the diagnosis and treatment of acute diffuse brain swelling (PADBS) and hyperbaric oxygen (HBO) after pediatric traumatic injury. Methods Retrospective analysis of 21 cases of children with clinical manifestations, CT images and HBO curative effect. Results In this group, 19 cases were cured by HBO. One case died of drug treatment and one case died of decompression. Conclusion The clinical manifestations of pediatric PADBS have no characteristics. CT is the preferred method of examination, manifested as diffuse brain swelling, appear early, brain CT values often increased. HBO treatment of this disease is effective, may be associated with HBO in the contraction of cerebral blood vessels, reduce cerebral blood flow at the same time, can increase cerebral blood flow and oxygen supply. Especially for simple brain swelling and GCS8 points in children with good results, can be used as early indications for the treatment of HBO.
