A large-bore nasogastric tube is inserted and is connected to suction. If lavage is ordered, 1 to 2 liters of room temperature normal saline is instilled via nasogastric tube and is then gently removed by intermittent suction or gravity until the secretions are clear. After lavage, the nasogastric tube may be left in or removed.
