"You said the blockage was not in the throat?" Zhang Huayao asked Xie Wanying while observing hard.

Blocked objects generally do not fall into the trachea immediately, which is why foreign objects in the airway are common, but suffocating when they fall into the trachea is not an unusual occurrence. The physiological reactions and structure of the human body are effectively preventing the accidentally swallowing of foreign objects in daily life.

The most common physiological reaction is pharyngeal reflex, that is, touching the back wall of the pharynx with a tongue pressing plate will cause nausea and vomiting.

The most important anatomical structure in our human body is called epiglottis. The last time the fiber clamping mirror has already mentioned this place. So what I want to say now is that if there is a foreign object, due to the physiological defense of the epiglottis, most foreign objects will be rejected and stuck in the surrounding area of ​​the epiglottis.

An experienced emergency department doctor will focus on patients who encounter foreign body obstruction.

Based on his previous observations in the oral cavity of the child and the preliminary judgment of brain formation, Xie Wanying said: "No foreign objects were found in the tonsils and oropharynx on both sides. No foreign objects were found at the intersection of the root of the tongue and the epiglottis. The place where foreign objects are often mentioned in textbooks are not abnormal, as is the piriform fossa on both sides of the throat entrance. Therefore, the blockage should have fallen into the trachea, which is expected to be on the trachea branch. The length of the trachea of ​​a five-year-old child is about five centimeters, so you can try to use foreign object forceps to remove it."

He is indeed an excellent medical student. Every place he says is a key point, making the teacher blameless. As she said, twenty or thirty percent of foreign objects will fall to the tonsils and oropharynx on both sides. Most of them will fall to the root of the tongue and epiglottis. As for the piriformes in the textbook, it is rare.

Zhang Huayao carefully examined these places and found no foreign objects. This is of course not a good thing for the children. As long as the doctor does not find foreign objects, the patient will die soon. Now he can only hope that the foreign objects fall into the trachea instead of the bronchial. As long as the direct laryngoscope can be found here, there is this opportunity to use direct laryngoscope and foreign object forceps to remove foreign objects.

Dongdongdongdongdongdongdong, Lin Liqiong ran back again, until she was about to break out of anger. This time, after the small blue box she brought in opened, she finally lived up to expectations and brought a direct laryngoscope.

"Do you have foreign object clamps?" Zhang Huayao asked.

"Yes." Lin Liqiong gasped and touched her white coat pocket. Maybe she was too anxious, and her hands couldn't help but tremble.

Xie Wanying reached out her hand and held her hand to help her stop trembling.

"Thank you." Lin Liqiong said in a low voice, calming down and touching out the things in her pocket, "I can only find this."

Zhang Huayao took the equipment she found and took a closer look, saying, "No."

"This is a tracheal intubation forceps." Cao Yong looked at it and knew something was wrong and said.

The classification of medical devices is very detailed. Although many times, doctors often use medical devices that are inappropriate to deal with patients with emergency treatment when they have no choice but to do so. However, some of them are really incomparable.
