Case #1

38 y.o male, found unresponsive at the bus station, with an empty oxycontin Rx container in his hand.

Pin-point pupils, SaO2 94%, GCS 11.

Case #1

Re-assessed 60 minutes later… SaO2 90%, occasional desats & apneic

periods GCS 8 PCO2 95 & pH 7.10 on VBG

How do you treat this patient’s toxidrome?

Case #1

IV naloxone can precipitate a life-threatening withdrawal reaction

IV access can be difficult

Needles convey a risk of exposure to blood bourne pathogens

Case #1

Nebulised Naloxone!

Case #1

Nebulised Naloxone, cont’d…

Weber et al, Pre-hospital Emergency Care 16: 2012

-105 patients

22%, complete response

59%, partial response

19%, no response

Case #1

Nebulised Naloxone, cont’d…

How many doses are required?

Weber et al, 10% of patients required IV rescue dose

Baumann et al, 40% of patients required > 1 dose

Case #1

Nebulised Naloxone, cont’d…

My Experience & Advice 2mg of naloxone & 3cc of normal saline

“Stimulate” patient to breathe

Allow patients to self titrate their medication

How much Naloxone do you have in your department?

Case #2

28 year old male.

MVC. Ejected from vehicle at 120 km/h

Arrives intubated, doesn’t move extremities

HR 65, BP 89/60

18 year old male, right sided thoracic stab wound.

Deviated trachea, shallow resps, absent right breath sounds.

Case #3

Are you in the right place?

Ferrie et al, Emerg Med J 2005;22:788–789

Case #3

Case #3

Is your patient too thick or your needle too short?

Case #3

Case #3

Is your patient too thick or your needle too short? Zengerink et al 2008

Retrospective review of Chest CTs for blunt trauma

Measured distance from skin to pleura at 2nd ICS, MCL

Mean CWT = 3.51cm right, 3.5cm left

19% of men had CWT > 4.5cm

35.4% of women had CWT > 4.5cm

Case #3

Is there a preferred alternate site of Needle Thoracostomy?

Inaba et al, 2011 Cadaver study. Needle thoracostomy at 2

different sites Does a lateral approach lead to more

successful placement?

Case #3

2nd ICS MCL

5th ICS MAL

Case #3

Is there a preferred alternate site of Needle Thoracostomy? Inaba et al, 2012

Step-wise increase in CWT across all BMI quartiles @ each location

CWT was less at 5th ICS

42.5% of patients had CWT >4.5CM @ MCL, & 16.7% @ 5th ICS

Case #4

56 year old obese male, collapsed and seized at a shopping mall food court.

Arrives in your ED GCS 3, sonorous resps and vomiting

Despite your best efforts, this patient desats before you can pass the ET tube
