Hypokalemia is a common condition that has been well studied. In most patients, mild hypokalemia is asymptomatic, while those with moderate-to-severe hypokalemia tend to show more prominent symptoms. In patients with a potassium level of 2.5 milliequivalents/liter (mEq/L) or lower, symptoms such as muscle cramps or weakness, rhabdomyolysis, and myoglobinuria tend to arise. These manifestations can lead to more debilitating consequences, such as renal failure secondary to rhabdomyolysis or respiratory failure secondary to muscle weakness. Other symptoms such as ileus, nausea, and vomiting, as well as cardiac arrhythmia and abnormalities, are also associated. Here we would like to present a patient with a potassium level of 1.4 mEq/L secondary to furosemide who presents to the emergency department with only complaints of muscle spasms for the past few days.
低钾血症是一种常见病症，已有大量研究。在大多数患者中，轻度低钾血症无症状，而中重度低钾血症患者往往表现出更明显的症状。血钾水平在 2.5 毫当量/升（mEq/L）或更低的患者，往往会出现肌肉痉挛或无力、横纹肌溶解和肌红蛋白尿等症状。这些表现可能导致更严重的后果，如横纹肌溶解导致的肾衰竭或肌肉无力导致的呼吸衰竭。其他症状如肠梗阻、恶心和呕吐，以及心律失常和异常，也与低钾血症相关。在这里，我们想介绍一位因呋塞米导致血钾 1.4 mEq/L 的患者，他因过去几天仅出现肌肉痉挛而到急诊科就诊。
