Female Proper Vs Improper Tracheal Intubation

The two nasal fossae extend from the nostrils to the nasopharynx.

Intubation anatomy. Endotracheal intubation can be performed either orally or nasally although oral intubation is the more commonly used technique5the nasopharynx and oropharynx lead to the laryngopharynx hypopharynx. The larynx is the key anatomical structure that needs to be identified when carrying out intubation. Intubation is then performed and tt position is checked by visualization of the carina through the tt and capnography.

Nasotracheal intubation is an alternative approach to orotracheal intubation. Saliva is temporarily held in the valleculae to prevent initiation of the swallowing reflex. If you cant recognize the vocal cords you will not be able to successfully intubate.

The ligaments of the larynx antero lateral view. Anatomical abnormalities may affect only intubation only airway management or both. These depressions serve as spit traps.

The nasal fossae are divided by the midline cartilaginous septum and medial portions of the lateral cartilages fig. At the base of the tongue the epiglottis separates the larynx from the laryngopharynx. Tracheal intubation usually simply referred to as intubation is the placement of a flexible plastic tube into the trachea windpipe to maintain an open airway or to serve as a conduit through which to administer certain drugs.

This is important of course. The epiglottic vallecula is a depression vallecula just behind the root of the tongue between the folds in the throat. The nasal fossa is bounded laterally by inferior middle and superior turbinate bones.

When first learning intubation a beginner often concentrates on memorizing the key laryngeal anatomy. The vallecula is an important reference landmark used during intubation of the trachea. This section also focuses on the abnormal airways in obesity pregnancy children and neonate and patients with abnormal facial defects.

It comprises of numerous separate cartilages held together with connective tissue. The larynx is a cartilaginous structure slung from the hyoid bone by the hyothyroid membrane. Anaesthesia is then induced using sevoflurane the cuff inflated and if necessary a neuromuscular blocking agent injected.
