team leader should establish the degree of practical<br />
expertise of the airway manager. For<br />
example, some doctors in training, such as<br />
junior residents, may not be comfortable<br />
managing a difficult airway such as in a<br />
patient who has sustained inhalation burns.<br />
The team leader should identify who may be<br />
needed to assist the team and how they can be<br />
quickly contacted.<br />
••<br />
If prehospital information suggests that the<br />
patient will require a definitive airway, it<br />
may be wise to draw up appropriate drugs for<br />
sedation and drug-assisted intubation before<br />
the patient arrives. Equipment for managing<br />
the difficult airway should also be located<br />
within easy access of the resuscitation room.<br />
••<br />
The timing of definitive airway management<br />
may require discussion with consultants to<br />
the trauma team. For example, in patients<br />
with head injuries who are not in obvious<br />
distress, discussion between the neurosurgical<br />
member of the team and the team leader may<br />
be helpful.<br />
••<br />
Patients may require transfer to the CT scan,<br />
operating room, or ICU. Therefore, the team<br />
leader should clarify who will be responsible<br />
for managing a patient’s airway and ventilation<br />
after intubation.<br />
Chapter Summary<br />
1. Clinical situations in which airway compromise is<br />
likely to occur include head trauma, maxillofacial<br />
trauma, neck trauma, laryngeal trauma, and airway<br />
obstruction due to other reasons.<br />
2. Actual or impending airway obstruction should be<br />
suspected in all injured patients. Objective signs<br />
of airway obstruction include agitation, cyanosis,<br />
abnormal breath sounds, hoarse voice, stridor<br />
tracheal displacement, and reduced responsiveness.<br />
3. Recognition of ventilatory compromise and ensuring<br />
effective ventilation are of primary importance.<br />
4. Techniques for establishing and maintaining a<br />
patent airway include the chin-lift and jaw-thrust<br />
maneuvers, oropharyngeal and nasopharyngeal<br />
airways, extraglottic and supraglottic devices,<br />
and endotracheal intubation. A surgical airway<br />
is indicated whenever an airway is needed and<br />
intubation is unsuccessful.<br />
5. With all airway maneuvers, cervical spinal motion<br />
must be restricted when injury is present<br />
or suspected.<br />
6. The assessment of airway patency and adequacy<br />
of ventilation must be performed quickly and<br />
accurately. Pulse oximetry and end-tidal CO 2<br />
measurement are essential.<br />
7. A definitive airway requires a tube placed in<br />
the trachea with the cuff inflated below the<br />
vocal cords, the tube connected to some form<br />
of oxygen-enriched assisted ventilation, and<br />
the airway secured in place with an appropriate<br />
stabilization method. Examples of definitive<br />
airways include endotracheal intubation and<br />
surgical airways (e.g., surgical cricothyroidotomy).<br />
A definitive airway should be established if there<br />
is any doubt about the integrity of the patient’s<br />
airway. A definitive airway should be placed<br />
early after the patient has been ventilated with<br />
oxygen-enriched air, to prevent prolonged periods<br />
of apnea.<br />
8. Drug-assisted intubation may be necessary in<br />
patients with an active gag reflex.<br />
9. To maintain a patient’s oxygenation, oxygenated<br />
inspired air is best provided via a tight-fitting<br />
oxygen reservoir face mask with a flow rate of<br />
greater than 10 L/min. Other methods (e.g., nasal<br />
catheter, nasal cannula, and non-rebreathing mask)<br />
can improve inspired oxygen concentration.<br />
