airway anatomy

air·way a·nat·o·my

(ār'wā ă-nat'ŏ-mē)
The tracheobronchial structure, similar in shape to that of an inverted tree, containing three types of airways: cartilaginous airways (trachea, main bronchi, and approximately five generations of small bronchi); membranous bronchioles (approximately eight generations of noncartilaginous airways); and respiratory bronchioles (approximately five generations of gas-exchange or alveolar ducts).

The McGrath VL results in a clear picture of the nearby airway anatomy and vocal cords on a liquid crystal display screen mounted on the handle.6 In 2633 general anesthesia cases, the incidence of failed intubation was one in 1300, and the incidence of difficult intubation was 4.7%, which is at the lower end of the recorded range of 1.3 to 16.3% in obstetric patients.7 Despite emerging evidence that VLs enhance the glottic view and improve intubation success rate, few studies have considered the function of this device, especially when used in obstetric patients.5 The primary objective of this study was to test the glottic visualization provided by the Macintosh direct laryngoscope (DL) and McGrath VL and the time taken to intubate patients undergoing cesarean section.
Particularly in children, more serious complications are likely to occur due to low reserves, different airway anatomy, and more fragile airway structures.
Your patient's airway anatomy may be difficult to visualise due to the large amount of blood which may mean they could be difficult to intubate, so keep the suction handy during this time.

The intubation success in this group may be associated with the similarity of the airway anatomy of these patients and the adult patients.
Even though difficult airway anatomy is frequently encountered in patients undergoing thoracic surgery, patients with FSS almost invariably present with a challenging anatomy.
On flexible bronchoscopy examination of her lower airways, no foreign body was seen, but significant external nonpulsatile compression over the left main bronchus was noticed; the rest of the airway anatomy was normal.
Patient sizes Typical nasal trumpet sizes (Fr) Large man 34, 30 Medium man 32, 28 Small man 30, 28 Large woman 32, 28 Medium woman 30, 28 Small woman 28, 26 Note: this is a general guide; however, the nasal trumpet sizes are also limited by additional physical attributes such as the presence of nasal septal deviations, the sizes of the inferior turbinates, and the general upper airway anatomy.

However, insertion of the LMA Classic is not always easy in children due to differences in airway anatomy compared with adults [9] and more complications are related to its use in younger children compared with adults.
