Extreme metabolic alkalosis and acute kidney injury in a 38-year-old male patient

We describe a case with life-threatening acid-base disturbances due to vomiting. A 38-year-old man presented to an emergency department with weakness and decreased urine output after having vomited up to 20 times per day over a period of 7 days. Arterial blood gas analysis revealed a metabolic alkalosis with partial respiratory compensation. Initial management consisted of oxygen therapy and intravenous fluid therapy with normal saline and potassium chloride. To prevent further gastric losses of HCl, proton-pump inhibitors and metoclopramide were administered. The vomiting was caused most likely by a temporary duodenal stenosis due to portal hypertension of unknown etiology. In our opinion, this case demonstrates the successful management of a life-threatening condition by simple measures. Despite extensive diagnostic procedures, the effective treatment of the underlying condition consisted of watchful waiting.
