Neck trauma Jasmin Fauteux August 25 th, 2011
2
Goals -Briefly review the basics -Review difficult cases and develop a clinical approach -Discuss
3
What this will NOT BE -A review of our textbooks -A repeat of the last 2 presentations -A monologue
4
22 yo female Brought from jail after cutting her neck with butter knife No suicidal intention HIV, HCV, ASPD No current bleeding VS Normal
5
Platysma Most superficial structure beneath skin Covers anterior triangle and anteroinferior aspect of posterior triangle.

Management +/- Flex endoscopy
12
Airway - Hard 46yo male, at church Shot in neck A Hoarse voice Air bubbling thru wound RR = 36 SaO2 = 89% 100NRB B Decreased AE x 2 C HR = 86 BP = 116/76 D GCS =15,PERL 3mm, MA4L E C-spine collar in place

15
C-spine precautions Normal neurologic exam in penetrating trauma does NOT require c-spine precautions
16
Airway - Soft
17
Clothesline accident 14yo M 60km/hr, 30 min ago A Minor hemoptysis, mild voice hoarseness B Sao2 = 99% on 8L NP, GAEB, WOB is N CNo other bleeding, HR = 84, BP =128/84 Rest of exam is unremarkable C-spine precautions +
18
Case 52 yo, penetrating nail injury Immediately removed nail Bleeding controlled
19
Case -ABC’s are all unremarkable -No hard or soft signs -Exploration, platysma is midly violated
20
-CTA: Trajectory visualized and not close to vital structures. Soft tissue injury only -Pt remains very well
21
If it violates the platysma, trauma wants to be involved
22
Case
23
Blunt neck trauma 48 yo M, restrained, driver vs moose ATalking full sentences, trachea central BGAEB, SaO2 = 99% RA CGood pulses bilat, BP = 124/76, HR = 88 DGCS = 15, PERL at 3mm, MA4L EC-spine collar Neck abrasion
24
Blunt trauma
25
1 Any c-spine fracture Neck soft tissue injury*
26
20-30% of pts have no identifiable criterias and go unscreened until they become symptomatic
27
Screening modality?
29
4 days later Pt returns with acute onset aphasia, facial droop and hemiparesis …
30
Hang in there!
31
Hanging Patient brought to rescus bay by EMS What do you want to know?
32
Strangulation vs hanging Judicial vs n-judicial Complete vs incomplete
33
ABC’s ALMA in place, bagged, good chest rise BGAEB, Sa02 = 98% CNSR, BP = 80/40 DPupils fixed at 2mm, GCS = 3 EC-spine collar in place Tardieu’s spots
34
On physical exam Ligature marks Tardieu’s spots Laryngo-tracheal symptoms Hoarseness, stridor, Focal tenderness or crepitation Dysphagia CNS depression from GCS 3 to nil Respiratory compromise from severe to nil
35
Up to 70% of hanging victims were found to be positive for EtOH or drugs
36
Over 90% of near-hanging victims will survive to be discharged Only 3,5% will have severe disability
37
Last case -28 yo F, assaulted by husband -Was strangulated -Witness states LOC ~ 1 min
38
79% of strangulation victims were assaulted by intimate partner
39
VS are normal and stable On exam, only finding is finger marks and ecchymosis of neck Who would CTA this patient?
40
Same patient, has minor hemoptysis and neck pain +++ on examination Who would CTA this patient now?
41
In summary Platysma violated = trauma consult Treat every neck trauma as a difficult airway & think ahead Know your hard & soft signs and investigate accordingly C-spine in penetrating if GSW + low GCS/neuro signs In blunt, think about BCVI In hangings: Resuscitate first, Prognosticate later* *P.
