I'm currently talking about head and neck emergencies that occur
0:05
very rarely in your experience as an emergency department
0:09
nor radiologist, but which are life threatening. Necrotizing
0:13
Fasciitis is a very dangerous infection that can occur after
0:18
dental infections, peri-tonsillar or pharyngeal abscesses,
0:22
oosteoradionecrosis , insect bites, previous surgery,
0:27
steroid neck injections, or skin popping by IV drug abusers.
0:32
What you see here is this very aggressive air forming bacteria
0:37
that is usually of a mixed flora that will aggressively
0:41
invade the fascia of the neck.
0:44
It will not respect the fascial boundaries of the
0:47
deep cervical fascia, be it the superficial,
0:49
middle or deep portions of the deep cervical fascia.
0:53
And what you see is just this gross area of necrosis
0:57
air in the neck bilaterally going through,
1:02
and the patient is just absolutely miserable.
1:06
And this has a very poor prognosis.
1:09
The risk factors for the patients, here we
1:12
have the risk factors of the infection,
1:13
but the patients that it occurs in include
1:16
those patients who are diabetics,
1:18
those patients who have severe atherosclerosis
1:20
with poor vascular supply to the neck anyway.
1:23
Alcoholics, chronic renal failure,
1:25
patients with malignancy who are unable
1:28
to mount an effective immune response,
1:30
the IV drug abusers who may be injecting in their
1:33
neck, or individuals in a postpartum situation.
1:36
So this is something that you want to recognize quickly.
1:41
Quite often they have to do surgery to remove
1:44
this necrotic tissue because, frankly,
1:47
the antibiotics don't help all that much without some surgical
1:50
intervention to decrease the overall
1:53
load of the inflammatory process.
