Gastric Lavage Synthesis

Satisfactory Essays

The purpose of the gastric lavage is to remove the excess paracetamol from the stomach lining to prevent it being broken down and absorbed in the gastrointestinal tract. However, this action must be taken within 2 to 4 hours after overdose as the drug may absorb into the systemic circulation (Forte, 2002). Activated charcoal absorbs the remaining doses of paracetamol and prevents its absorption into the systemic circulation of the body. This is most effective within 1 hour after ingestion of paracetamol (Thakore & Murphy, 2002). Although the combination of gastric lavage and activated charcoal treatment is often performed, it has been shown that activated charcoal is more effective alone (Christophersen, 2002).
