What is the purpose of an orogastric tube in overdose management?

• A. Removes toxins and irrigates stomach
• B. Delivers charcoal
• C. Measures acidity of stomach
• D. Delivers oxygen

Answer: (A)

An orogastric tube is used to decontaminate the stomach in overdose management. Inserting the tube and performing gastric lavage allows the clinician to physically remove undigested pills or toxins and then irrigate the stomach to flush out residual poison, reducing what can be absorbed into the bloodstream. This approach is most effective when done soon after ingestion and for substances that are amenable to lavage. It’s not about measuring stomach acidity or delivering oxygen. Activated charcoal can be given via the tube to adsorb remaining toxin, but that is a separate step from the lavage/irrigation purpose. The procedure carries risks such as aspiration and mucosal injury, so it’s used selectively with appropriate airway protection when needed.
