本实验观察了DMAP治疗不同程度的急性失血复合致死量氰中毒的效果。犬分别经股动脉急性失血至动脉收缩压9.33、6.67和5.33kPa造成轻、中、重度急性失血后复合iv NaCN2.5mg/kg中毒。对照组为轻度失血复合氰中毒不治疗,全组动物均在5 min...本实验观察了DMAP治疗不同程度的急性失血复合致死量氰中毒的效果。犬分别经股动脉急性失血至动脉收缩压9.33、6.67和5.33kPa造成轻、中、重度急性失血后复合iv NaCN2.5mg/kg中毒。对照组为轻度失血复合氰中毒不治疗,全组动物均在5 min内死亡;DMAP治疗各组在复合氰中毒后3 min iv DMAP 2 mg/kg治疗,动态监测血流动力学变化并同步作血气分析及MHb测定。结果发现,DMAP用于轻度失血复合氰中毒的治疗,有快速强效的心血管功能兴奋作用,起到挽救生命的效果;随失血程度加重,抗氰治疗难以奏效。血气分析及MHb测定结果表明,急性失血复合氰中毒时应用DMAP治疗可因过高的MHb浓度形成而严重影响血液携氧功能,提示在急性失血复合氰中毒时不用MHb形成剂类抗氰药为宜。展开更多

Reports on hepatotoxicity, mainly related to disulfiram therapy, have been published. The hepatotoxic potential of calcium carbimide is less well characterized. Here, we describe four cases of liver damage related to this therapeutic group that were submitted to a Registry of hepatotoxicity and point out the limitations that we face when prescribing these compounds.
