Abstract:
A 3.2-kg newborn was intubated for neonatal respiratory distress owing to a congenital tracheal stenosis. The preoperative assessment showed a sphincter-like stenosis located 1 cm above the carina. The child was cured by resection-anastomosis through sternotomy under cardiopulmonary bypass. The pathological examination showed hypoplastic cartilage islets embedded in a fibroelastic conjunctive tissue. The posterior membranous region was preserved with the existence of smooth muscle cells. This curious malformation resembled a diaphragm at the junction between trachea and carina.

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
