There is no set time for gastric lavage. It usually needs to be repeated until the liquid is washed out until it is clear and odorless.
Gastric lavage is a treatment in which a liquid of a certain composition is repeatedly pumped into the stomach and withdrawn. It can be used to remove unabsorbed poisons from the stomach or to clean the stomach lumen.
Gastric lavage includes oral emesis, gastric tube lavage, and dissection gastrostomy lavage. Because the nature of the poison, the amount of poison, and the absorption of the poison varies, the type of gastric lavage chosen varies, as does the duration of the gastric lavage.
Generally speaking, the higher the degree of cooperation of the patient, the shorter the time of taking the poison, and the smaller the amount taken, the shorter the time of gastric lavage, but ultimately, it should be ensured that the liquid to be washed out until it is transparent and tasteless.
In the case of accidental ingestion of poison requiring gastric lavage, it is recommended to cooperate with the doctor and let the doctor judge the duration of gastric lavage based on the condition of the liquid.
