Large-bore orogastric tube (Ewald/Faucher)
A single-lumen, large-bore tube (32-40 Fr, versus a standard ~14-18 Fr nasogastric tube) for rapid instillation or aspiration of gastric contents.
How it is used
Gastric decompression or lavage in upper-GI emergencies managed by the general surgeon (perforation, obstruction, variceal bleeding).
Clinical tip
Gastric lavage efficacy is strongly time-dependent: it is most useful only within the first hour after ingestion.
