Profound Alkalosis and Prolonged QT Interval Due to Inappropriate Gastrostomy Tube Loss: A Case Report.

INTRODUCTION: Severe metabolic alkaloses are relatively rare but can carry a high mortality rate. Treatment involves supportive care and treatment of underlying causes.

CASE REPORT: A 55-year-old male dependent on a gastrojejunostomy tube presented to the emergency department for altered mental status. The patient had metabolic alkalosis, electrolyte abnormalities, and prolonged QT interval on electrocardiogram. Examination and history revealed that chronic drainage of gastric fluid via malfunctioning a gastrojejunostomy tube resulted in profound alkalosis. The patient recovered with supportive care, electrolyte repletion, and gastrojejunostomy tube replacement.

CONCLUSION: This case highlights the importance of gastrointestinal acid-base pathophysiology.
