What are the examination items of congenital laryngeal atresia?

summary

Congenital laryngeal atresia is defined as congenital laryngeal atresia, in which the development of the larynx is blocked and the laryngeal cavity is not formed during the embryonic period, and the laryngeal cavity cannot be ventilated at birth. There are two kinds of membranous or cartilaginous, regardless of any atresia, there is often a small hole in the back of larynx, which is called eustachian tube catheter.

What are the examination items of congenital laryngeal atresia?

Although the child did not breathe after birth, he had obvious breathing movement, which can be distinguished from apnea caused by shock and cerebral hemorrhage. The color of the baby was normal at birth, and cyanosis appeared shortly after umbilical cord ligation, which could be differentiated from cardiac cyanosis. No crying and laryngeal ringing can be distinguished from other laryngeal or tracheal abnormalities.

There was no breathing or crying after birth. The soft tissue depression of suprasternal fossa, supraclavicular fossa, intercostal space, and subxiphoid process can be seen during inhalation, which is called inspiratory "four depression sign", but there is no air inhalation. At birth, the color of the baby was normal, but soon after the umbilical cord was ligated, cyanosis occurred due to hypoxia.

Diagnosis, according to the clinical manifestations and direct laryngoscope or fiber laryngoscope examination can be diagnosed. Examination, direct laryngoscopy or fiberoptic laryngoscopy. The cause of the disease is that the development of the larynx is blocked in the embryonic stage and the laryngeal cavity is not formed.

matters needing attention

If the children are not treated immediately, they will die soon after birth. If the newborn is found breathing without crying or air inhalation, the infant bronchoscope should be penetrated into the trachea immediately under the direct laryngoscope, and oxygen and artificial respiration can save the baby. If it is osteoatresia, tracheotomy should be performed immediately.
