Answer
Antibiotic, Penicillin and Beta-lactamase Inhibitor
These agents should be administered if evidence of perforation exists. A third-generation cephalosporin or ampicillin/sulbactam may be considered.
Ampicillin and sulbactam (Unasyn)
Drug combination of beta-lactamase inhibitor with ampicillin. Interferes with bacterial cell wall synthesis during active replication, causing bactericidal activity against susceptible organisms. Alternative to amoxicillin when unable to take medication orally.
Covers skin, enteric flora, and anaerobes. Not ideal for nosocomial pathogens.

Caustic ingestions. Endoscopic view of the esophagus in a patient who ingested hydrochloric acid (Lime-a-way). Note the extensive thrombosis of the esophageal submucosal vessels giving the appearance similar to chicken wire. Courtesy of Ferdinando L. Mirarchi, DO, Fred P.

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.
