麦角中毒Ergotismergotoxicosisergot poisoning)是长期麦角中毒的影响,在传统上,由于通过由感染黑麦和其它谷物麦角菌真菌产生的生物碱的摄取,以及最近的许多基于麦角灵药物的作用。它也被称为圣安东尼之火Saint Anthony's Fire)。

标志和症状

症状可大致分为惊厥症状和坏疽症状。

惊厥

惊厥症状包括抽搐疼痛和痉挛腹泻,皮肤感觉异常,瘙痒,精神的影响,包括躁狂或精神病,头痛,恶心和呕吐。通常情况下,胃肠道反应先于中枢神经系统的影响。

坏疽

干性坏疽是由真菌的麦角胺(ergotamine)-ergocristine生物碱诱导的血管收缩的结果。它会影响更弱的血管远端结构,如手指和脚趾。症状包括脱屑或脱皮,减弱周边脉搏,末梢感觉减退,浮肿,并最终死亡,受影响的组织的损失。血管收缩能被血管扩张剂治疗[1]
