- Gastric Lavage.

- Gastric lavage:- also commonly called Stomach wash or Gastric suction, is the process of cleaning out the contents of the stomach. It has been used for eliminating poisons from the stomach.

- Indications:-

1. With patient has ingested a potentially life-threatening amount of a poison and the procedure can be undertaken within 60 minutes of ingestion.
2. Cleaning the stomach before an upper endoscopy in someone who has been vomiting blood.
3. Collecting stomach acid for tests.
4. Relieving pressure in someone with a blockage in the intestines.

- Contraindications :-

1. Loss of airway protective reflexes, such as in a patient with a depressed state of consciousness.
2. Ingestion of a corrosive substance such as a strong acid or alkali.
3. Ingestion of a hydrocarbon with high aspiration potential.
4. Patients who are at risk of hemorrhage or gastrointestinal perforation due to pathology, recent surgery, or other medical condition, that could be further compromised by the use of gastric lavage.

- Complications:-

• Aspiration pneumonia.
• Laryngospasm.
• Hypoxia and hypercapnia.
• Mechanical injury to the throat, esophagus, and stomach.
• Fluid and electrolyte imbalance.
• Struggling patients may be at greater risk of complications

- Technique:-

1. Gastric lavage involves the passage of a tube via the mouth or nose down into the stomach, followed by sequential administration and removal of small volumes of liquid.
2. The placement of the tube in the stomach must be confirmed either by air insufflation while listening to the stomach, by pH testing a small amount of aspirated stomach contents, or x-ray. This is to ensure the tube is not in the lungs.
3. Lavage is repeated until the returning fluid shows no further gastric contents.
4.  If the patient is unconscious or cannot protect their airway then the patient should be intubated before performing lavage.
