Airway
Due to rapid changes in the accepted standards of practice for airway
management and the proliferation in available technical equipment for
managing airway problems, we feel that all residents should complete a
mandatory airway rotation in their senior years (PGY3 – PGY5). This
rotation will be one month in duration and will occur at the General
Campus focusing on adult patients. The resident will continue to assume
their usual night call duties. Experience with airway equipment should
ideally be obtained under the supervision of a staff anesthesiologist in
patients with a normal airway evaluation, ASA class I or II, scheduled
for an elective procedure in the supine position, and not requiring
extensive monitoring or involving the head or neck. Key articles will
be identified for directed study during the rotation. The anesthesia
simulator or an airway mannequin will be used to practice infrequent
techniques such as retrograde intubation, or insertion of a combitube.
Patients identified to have an abnormal airway and requiring awake
intubation will be prioritized to the airway resident when feasible. We
will try to avoid the having the resident move from room to room to
gather experience, rather, the resident will be assigned to a single
room to gain experience on airway techniques on two to four patients per
day (40 – 50 patients per rotation). Faculty with an interest in
teaching airway management skills will be scheduled to work with the
airway resident.
Residents are directed to review existing expert publications on the
proper use of various airway devices (O. Hung, Bullard, Brain, etc),
rather than struggling with unfamiliar equipment and acquiring
unconventional personal techniques. (Recommended text: JL Benumof.
Airway Management, Principles and Practice. Mosby 1996, and Finucane
B.T. Principles of Airway Management. Mosby 1996, both available in
the anesthesia library). When possible the departmental airway
mannequin should be utilized to gain experience with unfamiliar airway
equipment.
The suggested progression during the month airway rotation is to gain
experience in:
1.
Inhalational induction
2.
Alternatives to bag mask ventilation with the LMA and Fastrak:
a.
Intravenous induction
b.
Inhalational induction
3.
Adjuncts to the direct laryngoscope
a.
Bougie
b.
Straight Blade
c.
McCoy Blade
4.
Alternatives to the direct laryngoscope
a.
Trachlight
b.
Bullard Laryngoscope (with and without video)
5.
Flexible fiberoptic intubation
a.
Awake
b.
Asleep
6. Review of exposure and remedial supplemental training.
An
afternoon session at the medical school anatomy lab to gain experience
with more invasive techniques such as retrograde intubation and
cricothyroidotomy can be arranged if interested. This would also allow
for dissection and anatomical study of the airway and can be arranged on
an intermittent basis every 3 – 4 months with a limited number of
residents who have completed or will be completing their airway
rotation.
