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.

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
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
. Fr = French.

This shape mimics upper airway anatomy
, resulting in low resistance and allowing 'anatomical' insertion.
However, insertion of the LMA Classic is not always easy in children due to differences in airway anatomy
compared with adults  and more complications are related to its use in younger children compared with adults.
