Contraindications to gastric lavage for all types of poisoning include swallowing strong corrosive agents, gastric perforation, esophageal varices, aortic aneurysm, etc.
Contraindications to gastric lavage mainly include swallowing strong corrosive agents, which can easily lead to gastric perforation and other serious complications.
Those with esophageal varices, aortic aneurysms, suspected aortic coarctation, and severe cardiopulmonary diseases cannot have gastric lavage. Gastric lavage may aggravate the condition and worsen the complications, which may be life-threatening.
It should be noted that if the patient is in a deep coma before gastric lavage or has lost the ability to protect the airway, endotracheal intubation should be performed before gastric lavage in order to avoid the occurrence of aspiration.
In the process of gastric lavage, if the patient has symptoms of abdominal pain, or bleeding lavage fluid, or shock, the lavage should be stopped immediately, and notify the relevant doctors for symptomatic treatment. After gastric lavage, it is generally necessary to fast for a period of time, so that the gastric mucosa can be restored accordingly.
If toxicity is considered and gastric lavage is needed, it is necessary to go to the hospital and choose the appropriate solution under the guidance of the doctor.
