Crotalic envenomation is responsible for approximately 8%-13% of ophidism cases in Brazil, yet it is associated with the highest mortality among snakes. We describe the case of a patient bitten by a rattlesnake who developed ventilatory muscle paralysis within hours after envenomation. While diaphragmatic paralysis is a rare late neurotoxic event following crotalic envenomation, in this case, paralysis occurred early but was rapidly reversed after antivenom administration. This report discusses potential contributing factors based on a comprehensive literature review.
响尾蛇咬伤约占巴西蛇伤病例的 8%-13%，但其死亡率却是所有蛇类中最高的。我们报告了 1 例响尾蛇咬伤患者，在咬伤后数小时内出现呼吸肌瘫痪。膈肌瘫痪是响尾蛇咬伤后罕见的迟发性神经毒性事件，但本例患者的瘫痪发生较早，在使用抗蛇毒血清治疗后迅速逆转。本报告基于全面的文献复习讨论了潜在的促成因素。
