The use of soapy water for gastric lavage can have the effect of inducing vomiting, but it can cause an irritating reaction to the gastrointestinal tract, and therefore there is a risk of burns or ulcers of the gastric mucosa following gastric lavage.
Soap water can be used for gastric lavage. Appropriate consumption of soap can effectively stimulate the gastrointestinal tract, prompting vomiting, and thus can help to alleviate oral poisoning or gastrointestinal poisoning reactions. However, because of the predominantly alkaline drug content of soap water, it can affect the pH of gastric acid upon entering the gastrointestinal tract and cause irritation of the gastrointestinal mucosa.
Therefore, improper use of soapy water may instead cause burns or ulcers of the gastrointestinal mucosa. Generally, when gastric lavage is required, the use of soapy water is not recommended. Saline can be used for gastric lavage, and surgical procedures can be performed directly to clean the gastrointestinal tract and thus facilitate the elimination of toxic components.
Only when professional medical treatment is not possible, a small amount of soap water can be consumed to induce vomiting, but after treatment it is still necessary to effectively wash the soap components.
When gastric lavage is required, it should be done with the appropriate medication under medical supervision.
