For the symptoms of accidental ingestion of lime desiccant, lime desiccant is a commonly used desiccant, the main component is calcium oxide, the substance is white crystal particles in anhydrous state, if such desiccant is mistakenly taken, calcium oxide will become calcium hydroxide when it meets water, and at the same time, heat will be released, which will burn the mouth and esophagus. If eating more and burns occur, inflammation, congestion and edema of the mucous membrane around the mouth will be found, and a burning sensation and painful swallowing of things will occur after the esophagus is injured. In addition, if it accidentally enters the eyes, it can also cause damage to the conjunctiva and cornea, resulting in eye congestion, edema, tearing, photophobia, etc. In case of accidental ingestion, patients are advised to drink milk immediately, do not induce vomiting, and do not neutralize with other acid substances. If only a small amount of desiccant is taken by mistake, without causing obvious discomfort in the mouth and gastrointestinal tract, the effect on human body is not great. If the accidental intake is larger and obvious oral mucosa and esophageal damage occurs, the patient is advised to go to the hospital immediately for symptomatic treatment.
