According to the mother of A.T (5 years old), after the child played with slime, the child had a hand on his face and complained of bitterness in the eyes. About 20 - 30 minutes later, the child's eyes and mouth began to swell with vomiting and coughing.
It is worth noting that the child was completely healthy before, had no history of allergies, and this was the first time the child had contact with slime. Immediately upon admission, doctors conducted an examination and quickly determined that baby A.T had Quincke edema (also known as bulge) - a form of acute allergic reaction that causes swelling in the deep layer of the skin and mucous membranes, which can cause airway obstruction if it spreads to the throat and laryngosphere.
Doctors immediately treated the child with Solu-Medrol (antimicrobial anti-inflammatory drug) and Dimedrol (antimicrobial anti- histamin to reduce allergic reactions) and closely monitored the possibility of grade 2 anaphylactic shock - a severe anaphylaxis that can be life-threatening.
The doctor also considers using adrenalin if the patient's condition progresses. Fortunately, after 20 minutes of doctor intervention and close monitoring, the child's edema improved, no more symptoms appeared, the child and the family gradually stabilized and did not need to take adrenalin.

BSCKI. Hoang Minh Hung (Pediatric Department - Hong Ngoc Phuc Truong Minh General Hospital) - directly treating the child patient said: "We have received many cases of anaphylactic shock, edema, and brittle brocade after contact with strange toys of unknown origin containing colorants, odorants, or preservatives exceeding regulations. Some children develop rapidly to the point of respiratory failure, affecting the nervous system and having to undergo long-term treatment".
Doctors recommend that parents should be cautious when choosing toys for their children, prioritize products purchased at reputable stores, clear origins, and safety certificates, avoid toys with strong scents and unusually colorful colors, especially slime, clay, water toys, etc. floating on the market.
In addition, if you see children showing unusual signs such as: Itching, rash, swelling in the lips and eyes, abdominal pain, vomiting, coughing, wheezing, shortness of breath, ... you should stop contact immediately and take the child to the nearest medical facility.
The case of baby A.T was very lucky because the family promptly discovered it and the baby was given early intervention and treatment, so he stabilized early and did not have dangerous complications."
