Respiratory arrest.
Cardiac arrest
The following are only relative contraindications to
tracheal intubation:
Severe airway trauma or obstruction that does
such as bronchoscopy
less kinking of tube
DISADVANTAGES
not recommended in patients with suspended
cervical injury
uncomfortable
mouth care more difficult to perform
impairs ability to gag and swallow
may increase salivation
may cause irritation and ulceration of the
mouth
NASAL ENDOTRACHEAL INTUBATION
The ET is placed blindingly (ie. Without visualizing the
larynx) through the nose, nasopharynx and vocal cords.
procedure.
Nasotracheal intubation can also be performed through
direct visualization. In this method, practitioners may
use a laryngoscope and Magill forceps or fiberoptic
bronchoscopy during the intubation.
ADVANTAGES
greater patient comfort and better tolerance
better mouth care possible
fewer oral complication
less risk of accidental extubation
facilitates swallowing of secretions
can administer small amounts of oral liquids
if patient able to swallow
DISADVANTAGES
more difficult to perform
may cause nasal hemorrhage and sinusitis
secretion removal more difficult because
of smaller tube diameter and longer tube length
Several complications may occur as a result of
oral endotracheal or nasotracheal intubation.
Complications include-
trauma to airway structures
hypoxia
dysrhythmias
aspiration
an endotracheal tube that is mistakenly
sized or misplaced, especially in the apneic
patient, can quickly lead to hypoxia and
death
Broken teeth or dentures
Adequate ventilation is dependent on the free
movement of air through the upper and lower
airways. In many conditions, the airway becomes
narrowed or blocked as a result of disease process,
broncho-constriction, foreign body or secretions.
