Acacia beans contain acacia toxic protein, which at very low concentrations may lead to red blood cell agglutination and hemolytic reactions, and in severe cases can be life-threatening. First aid as well as therapeutic measures include blocking the absorption of poison, protecting the digestive tract, removing blood toxins, protecting organ function, and maintaining blood volume. 1. Blocking the absorption of poison: When patients take acacia beans by mouth, they should immediately induce vomiting and gastric lavage to block the further absorption of poison. 2. Protect the digestive tract: drinking milk, egg white, etc. can protect the gastric mucosa, because the serum gastrin content is high in patients with acute poisoning, and there is a certain relationship between elevated gastric acid and gastrointestinal bleeding, so whether or not there is gastrointestinal bleeding, should be used as soon as possible, such as omeprazole and other proton pump inhibitors. 3. Removal of blood toxins: the body can be removed by blood perfusion of phasin toxic proteins as well as toxic metabolites. 4. Maintaining blood volume: blood volume should be replenished as soon as possible, and drugs such as saline can be supplemented intravenously to correct shock and ensure blood flow to important organs such as kidneys. Those with renal bleeding use sodium bicarbonate to alkalize the urine, reduce hemoglobinuria or its products deposited in the kidneys and damage the kidneys. The above medications need to be administered under medical supervision, and suspected acacia bean poisoning is recommended to go to the emergency department of the hospital in time.
