【摘要】本文对以痫性发作为主要表现的乳酸酸中毒2例病例进行报告,分别探讨了乳酸酸中毒、痫性发作的发病机制,并试图找到两者之间的关联点。另外,在临床诊治过程中,乳酸酸中毒极易漏诊,对于癫痫发作的患者,建议常规完善血气分析检查,以排除乳酸酸中毒,避免漏诊,使乳酸酸中毒得到及早、有效的治疗。

[Abstract] In this paper, there are 2 report cases about the epileptiform seizure as the main performance of lactic acidosis, respectively discussed the pathogenesis of lactic acidosis and epilepsy, and tries to find the correlation between the two points. In addition, in the process of clinical diagnosis and treatment, lactic acidosis is easily missed diagnosis, for patients with epileptiform seizure, we should complete the blood gas analysis in order to remove the diagnosis of lactic acidosis, avoid missed diagnosis, make lactic acidosis effective treated as early as possible.

乳酸酸中毒(1actic acidosis,LA)是一種血乳酸持续升高和血pH降低所致的临床综合征,当动脉血乳酸水平持续升高(>5 mmol/L),伴有代谢性酸中毒,HCO3-<10 mmol/ L,定义为乳酸酸中毒(LA)[9]。乳酸酸中毒起病急,轻者可有恶心、呕吐、腹痛、腹泻、不明原因的深大呼吸,重者有低血压、氧饱和度下降、神志模糊、嗜睡、木僵及昏迷等症状,其病情进展快,死亡率随血乳酸水平增高而增加[10],死亡率可高达80%[11],及早诊断和有效治疗对于挽救乳酸酸中毒患者生命具有重要意义。而在多年的临床诊治过程中,笔者有幸诊治2例以痫性发作为主要症状的乳酸酸中毒患者。现将2例病例临床特点及诊治体会及相关发病机制进行报告分析如下。
