[Condition of the larynx affected by the laryngeal mask during general anesthesia]
Abstract:
A new generation artificial airway--a laryngeal mask (LM)--was examined for effects on a laryngeal function in general anesthesia. Topographic-anatomic characteristics of the upper respiratory tracts which make impossible an adequate wearing of LM as well as frequency and severity of laryngeal LM-induced complications were specified. The comparison of the changes in the laryngopharynx and larynx due to LM and endotracheal tube has demonstrated that LM is more safe for anatomic and functional state of the larynx and for mucosa of the upper respiratory tracts than the tube. LM provides general anesthesia in problematic intubation. Employment of LM raises quality of anesthesia, reduces the number of intra- and postoperative laryngeal complications in conduction of general anesthesia.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

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,...
