- Treatment: 对有毒表现患者的治疗包括确保并维持患者气道,并根据需要支持通气(呼吸)。在大多数反应的管理中,这通常是足够的。如果抽搐持续存在 despite 通气治疗,可静脉给予小剂量的抗惊厥药,如苯二氮卓类(例如,地西泮)或超短效巴比妥类药物(例如,硫喷妥钠或硫戊巴比妥)或短效巴比妥类药物(例如,戊巴比妥或司可巴比妥)。心血管抑制可能需要根据临床情况静脉输液和/或血管加压剂(例如,麻黄碱)进行循环支持。(L1712)
- exposure pathway: 局部吸收。局部麻醉剂的全身吸收速率取决于给药的总剂量和浓度、给药途径、给药部位的血管分布以及麻醉液中是否存在肾上腺素。皮下注射;浸润
- Toxicity summary: 局部麻醉药通过增加神经电兴奋的阈值、减慢神经冲动的传导速度以及降低动作电位的上升速率,来阻断神经冲动的产生和传导。一般来说,麻醉的进展与受影响神经纤维的直径、髓鞘形成和传导速度有关。临床上,神经功能丧失的顺序如下:痛觉、温度、触觉、本体感觉和骨骼肌张力。
- Toxicity Data: 在恒河猴中,美匹卡因的平均惊厥剂量为18.8 mg/kg,平均动脉血浆浓度为24.4 µg/mL。LD50: 23-35 mg/kg (静脉注射,小鼠) (A308) LD50: 280 mg/kg (皮下注射,小鼠) (A308)
- Hazard categories and classifications: 急性毒性 3 (100%)

- Effects During Pregnancy and Lactation: 一项全国性调查对从妊娠晚期到产后12个月的妇女及其婴儿进行了研究,比较了分娩期间接受和未接受止痛药的产妇泌乳II期的时间。药物类别包括仅脊髓或硬膜外麻醉、脊髓或硬膜外麻醉加其他药物、以及其他止痛药。任何类别接受药物的妇女发生延迟泌乳II期(>72小时)的风险约为未接受分娩止痛药妇女的两倍。
