He is a 2 year old boy who is very naughty. Recently, he has been coughing for 2 months and has used various antibiotics and cough suppressants to no avail. The local doctor intended to treat him as asthma. The parents came to our hospital anxiously, and we mobilized him for a bronchoscopy. Little Haunted, under the anesthetic effect of lidocaine and midazolam, yawned and fell asleep, and quietly underwent the examination. Half an hour later, half a rotten peanut rice was taken out, and Haunted’s cough was completely cured.
