- Treatment: 全身毒性反应管理的第一步是立即关注建立和维持通畅的气道,并使用能够通过面罩立即提供正气道压力的氧气和输送系统进行辅助或控制通气。如果发生惊厥,治疗的目标是维持通气和氧合,并支持循环。必须给予氧气,必要时进行辅助通气(面罩和气囊或气管插管)。如果惊厥在15-20秒后没有自发停止,应静脉给予抗惊厥药以促进充分通气和氧合。硫喷妥钠1-3毫克/公斤静脉是首选。 alternatively 可使用地西泮0.1毫克/公斤体重静脉注射,尽管其作用将...
- exposure pathway: 静脉注射、外用、口服、颊部、牙科、肌肉注射或尿道注射。源自不同配方、浓度和用法的资料显示,利多卡因在胃肠外给药后完全吸收,其吸收速率取决于例如给药部位以及是否存在血管收缩剂等各种因素
- Toxicity summary: 利多卡因通过抑制冲动启动和传导所需的离子流来稳定神经元膜,从而产生局部麻醉作用。利多卡因通过阻断神经元细胞膜中负责信号传播的快速电压门控钠(Na+)通道来改变神经元中的信号传导。在充分阻断的情况下,突触后神经元的膜将不会去极化,因此无法传递动作电位。这不仅通过阻止疼痛信号传播到大脑,而且通过首先阻止它们的产生来产生麻醉效果。
- Regulatory information: 新西兰EPA化学品清单状态:盐酸利多卡因:没有单独批准,但可在适当的团体标准下使用
- Toxicity Data: LD50: 459 (346-773) mg/kg (口服,非禁食雌性大鼠) LD50: 214 (159-324) mg/kg (口服,禁食雌性大鼠)
- Health Effects: 过量接触利多卡因主要导致中枢神经系统(CNS)和心血管系统影响。CNS影响可能包括CNS兴奋(紧张、口周刺痛)随后抑制。[维基百科]
- Symptoms and Signs: 过量症状包括惊厥、缺氧、酸中毒、心动过缓、心律失常和心脏骤停。
- Other safety information: 化学品评估:IMAP评估 - 2-(二乙氨基)-N-(2,6-二甲基苯基)乙酰胺盐酸盐:人类健康I级评估
- Hazard categories and classifications: 急性毒性 4 (17.5%)
- Carcinogen Classification: 对人类无致癌性迹象(未被IARC列出)。
- Effects During Pregnancy and Lactation: 一项埃及研究比较了2%利多卡因(n = 75)与2%利多卡因加1:200,000肾上腺素(n = 70)作为剖宫产后的伤口浸润。接受利多卡因联合肾上腺素的患者在手术后89分钟开始哺乳,而单独接受利多卡因的患者为132分钟。差异具有统计学意义。
