title: Hypochloremic metabolic alkalosis following tolazoline-induced gastric hypersecretion.
abstract: Gastric hypersecretion following administration of tolazoline resulted in severe hypochloremic alkalosis in an infant with persistent fetal circulation. An initial bolus injection of 2 mg/kg was followed by an infusion of 5 mg/kg/hr for 24 hours. The infusion was then maintained at 2 mg/kg/hr for the next four days. Volume of gastric secretions exceeded 25 ml/kg/24 hr. Weaning from tolazoline and replacement of chloride and potassium corrected the metabolic alkalosis.
