Treatment of poisoning:Gastric lavage
Treatment of Poisoning includes :
- Immediate resuscitative measures :To follow ABCD protocal, i.e. mangement of airway, breathing, circulation and depression of CNS
- Removal of unabsorbed Poison: depends upon the mode of intake of the poison for eg: In Ingested Poisons: Vomiting , gastric lavage(stomach wash), Emesis can be done .
- Use of antidote : Antidote is given to counteract or neutralize the effect of poison.
- Elimination of already absorbed poison: By forced diuresis (alkaline or acid diuresis), dialysis (peritoneal dialysis or hemodialysis).
One of the important treatment is 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.
- It is most effective if done within 3-6 hours of poisoning.
- In gastric lavage, stomach is washed by warm water; 1:5000 KMnO4 ; tannic acid; sodium bicarbonate; sodium or potassium iodide; calcium lactate, saturated lime water or starch solution or 0.9% saline.
Contradictions:
- Non- live threatening ingestions & non- toxic ingestions.
- Pills that are known not to fit into the holes of the gastric lavage tube.
- Any pt. whose air integrity is not assured.
- The only obsolute contraindication is corrosive poisoning, i.e. alkalis, mineral acid, vegetable acid and organic acids (except carbolic acid).
- Carbolic acid is the only corrosive in which gastric lavage can be used. P.M findings shows leathery stomach in case of carbolic poisoning
- Toxic ingestions with more pulmonary than G.I.T Toxicity e.g. kerosene (to avoid aspiration).
Complication:
- Insertion of the tube in to the trachea obstructing it.
- Aspiration pneumonitis,
- Esophageal or gastric perforation.
- Decreased oxygenation during the procedure.
