GASTRIC LAVAGE CYTOLOGY***

No Patient preparation is needed

Gastric lavage may be contraindicated in individuals at risk of gastrointestinal hemorrhages, such as those with coagulopathies or after surgery; in cases of caustic ingestion (i.e., ingestion of strongly acidic or alkaline substances); or when the airway is unprotected, such as when essential reflexes are lost, and no endotracheal intubation was performed beforehand.
