“…This report emphasized the importance of timely CPR as well as the assessment and replacement of potassium in patients with hypokalemia who present with cardiac arrest. When severe cardiac arrest or instability due to hypokalemia is recognized, advanced cardiac life support or other relevant resuscitation protocols should be implemented immediately [11]. In the case of severe hypokalemia, immediate potassium replacement may be life-saving, and central venous access is critical.…”

Fanconi syndrome is a multi-factorial disorder that involves diffuse malfunction of the proximal convoluted tubule in the kidney. Renal wasting of potassium, glucose, bicarbonate, amino acids, and phosphorus characterize the condition. We report a case of a 57-year-old female who presented to our emergency department with cardiopulmonary arrest. After successful resuscitation, she had extensive workup to uncover the cause of her cardiac arrest. She had extensive negative workup but was found to have severely low potassium, prompting further evaluation. She was noted to have elevated urine potassium, with a transtubular potassium gradient of 9. She was also found to have severe glycosuria, hypophosphatemia, proteinuria, and an elevated urine anion gap, suggesting proximal convoluted tubular dysfunction. The hypokalemia noted on admission was thought to have been the causative factor for the cardiopulmonary arrest and was thought to be due to proximal tubule dysfunction, with the major suspected diagnosis being a Fanconi-like syndrome. This report highlights the diagnosis and treatment of hypokalemia, the broad differential involved with hypokalemia, and the syndromes involved with renal potassium wasting. This report also seeks to raise awareness of the association of renal potassium wasting with cardiopulmonary arrest.

“…It is important to closely monitor cardiac status while administering potassium. It is also important to adjust infusion rates according to ECG changes in cardiac monitoring [11,12]. In severe potassium fluctuations or cardiac arrest, additional infusions such as calcium and magnesium can also be beneficial [11,12].…”
