背景:锡兰krait(Bungarusceylonicus)是斯里兰卡特有的一种有毒的蛇形蛇。它栖息在斯里兰卡潮湿地区阴暗的家庭花园和森林中,并可能在夜间潜入房屋。尽管经常与人类相遇,关于envenoming的报道非常罕见。
方法:我们报告了一例26岁的斯里兰卡僧伽罗人,证实锡兰kraitvenoming,表现为双侧部分下垂,眼肌麻痹,面部肌肉无力,和吞咽困难.单纤维肌电图和重复神经刺激证实了神经肌肉麻痹。入院后立即给予他多价抗毒血清,但没有迅速的临床反应。咬伤后3天观察到完全恢复。
结论:由于罕见的envening,缺乏关于envenoming后临床表现的准确和详细信息。然而,锡兰krait咬伤可能致命;所以,治疗医生应该意识到物种识别,栖息地,锡兰krait的咬人习惯和临床表现。此病例报告增加了有关锡兰kraitenvenoming的现有有限文献的知识;一种罕见但可能致命的临床实体。
BACKGROUND: Ceylon krait (Bungarus ceylonicus) is a venomous elapid snake endemic to Sri Lanka. It inhabits shaded home gardens and forests in the wet zone of Sri Lanka and might creep into houses in the night. Despite frequent encounters with humans,
reports of envenoming are very rare.
METHODS: We report a
case of a 26-year-old Sri Lankan Sinhalese man with confirmed Ceylon krait envenoming presenting with bilateral partial ptosis, ophthalmoplegia, facial muscle weakness, and dysphagia. Single fiber electromyography and repetitive nerve stimulation confirmed neuromuscular paralysis. He was administered polyvalent anti-venom serum immediately following admission without a prompt clinical response. Complete recovery was observed 3 days following the bite.
CONCLUSIONS: Because of the rarity of envenoming, precise and detailed information on the clinical manifestations following envenoming is lacking. However, Ceylon krait bite can be potentially fatal; so, treating physicians should be aware of species identification, habitat, and biting habits and clinical presentation of envenoming of Ceylon krait. This
case report adds knowledge to the existing limited literature available on Ceylon krait envenoming; a rare but potentially fatal clinical entity.
