In patients with caustic ingestion, airway monitoring and control is the first priority. When airway compromise is present, a definitive airway must be established. In patients with a stable airway and no clinical or radiological sign of perforation, medical therapy should be initiated. [13, 14, 15, 16]
Arrangements should be made for urgent esophagogastroduodenoscopy (EGD) to grade the degree of injury and establish long-term prognosis, In asymptomatic patients, however, EGD may be withheld in favor of observation. Pediatric patients who remain asymptomatic for 2 - 4 hours after an exploratory ingestion and who are tolerating a normal diet may be discharged with appropriate follow-up and return precautions. Surgical consultation is indicated for suspected perforation. Because of the risk of late complications—most commonly, esophageal stricture formation—arrangements for follow-up need to be made.

Algorithm for the diagnosis and management of caustic ingestions. In all cases of caustic ingestion, the airway should be assessed initially and protected if necessary. If endoscopy is not rapidly available and severe injury is strongly suspected, obtain a contrast-enhanced computed tomographic (CT) study. The Usta protocol consists of methylprednisolone (1 g per 1.73 m2 of body-surface area per day, given intravenously for 3 days) plus ranitidine (4 mg per kilogram of body weight per day in children or the standard adult dose in adults, given intravenously) plus ceftriaxone (100 mg per kilogram per day in children or the standard adult dose in adults, given intravenously). NPO denotes nothing by mouth, and TPN total parenteral nutrition.
