The beneficial effect of dopamine in circulatory shock induced by tricyclic antidepressants (TCA) overdose may be decreased due to compromise of the endogenous stores of norepinephrine caused by TCA. The successful outcome of two cases of TCA overdose complicated by hypotension, unresponsive to an initial treatment with physostigmine fluid challenge and dopamine (greater than 15 micrograms/kg/min) but subsequently responsive to an infusion of norepinephrine is reported.
三环类抗抑郁药(TCA)过量引起的循环性休克中,多巴胺的有益作用可能会因TCA导致的内源性去甲肾上腺素储备受损而降低。本文报告了两例TCA过量并发低血压的病例,最初使用毒扁豆碱补液试验和多巴胺(大于15微克/千克/分钟)治疗无效,但随后输注去甲肾上腺素后病情好转。
