A 36-year-old man who completed a marathon six hours earlier presents to the emergency de- partment with severe muscle pain and swelling and complaints of red urine. Laboratory tests show a creatine kinase level of 6800 U/L but no RBCs or WBCs on urinalysis. Which of the following symptoms would most likely also be present?
一名在6小时前完成马拉松的36岁男性因严重肌肉疼痛、肿胀和尿红色主诉到急诊科就诊。实验室检查显示肌酸激酶水平为6800 U/L,但尿液分析中无红细胞或白细胞。下列哪一种症状最有可能也会出现?
(A) Arrhythmia 心律失常
(B) Hepatomegaly 肝肿大
(C) Pain in a dermatomal distribution 皮区的疼痛
(D) Pain on urination 排尿疼痛
(E) Shuffling gait 蹒跚步态
答案解析:
患者经历了继发于极度肌肉拉伤的横纹肌溶解。横纹肌溶解导致肌细胞内容物释放到血流中,导致肌酸激酶水平升高和肌红蛋白尿(红色尿液,尿液试纸检查血液阳性,但尿分析无红细胞)。细胞内钾离子的释放可导致严重心律失常的发生,并可能导致死亡。
正确答案:A
