Plant = equipment and drugs
Prepare ultrasound machine, blood, drugs eg analgesics, airway equipment etc as required based on the information you have
![Page 14: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/14.jpg)
Plan
Talk through your plan based on what you know with the team
As you think out loud others can chip in with things you may not have thought of
Gets everyone on the same page
But remember the plan may change rapidly

ABCDEfG
Can be applied to 95% of what we see in ED
Use it for your approach and your documentation

Stabilise c-spine with collar Grip head and shoulders when movingControlled slide on sliding board OK

Basic airway maneuvers
What are they?
![Page 21: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/21.jpg)
Jaw thrust - mainly we do this one
Chin lift
Head tilt
![Page 22: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/22.jpg)
Basic airway adjuncts
What are they?
What size do you use?
![Page 23: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/23.jpg)
OPA = Guedelo Size from corner of mouth to angle of jaw
o Insert upside down in adult, then rotateo Insert right way up in kidso If the patient tolerates an OPA that’s a fairly good
indication they aren’t protecting their airway and probably need to be intubated

NPAo From nostril to tragus
LMAo Weight written on packet. o 5: adult maleo 4: adult female

Bag-Valve-Mask
o Essential skill
o Mask fits over bridge of nose and below lower lip but not under chin
o Little finger behind ramus of mandible to lift jaw forward
o Use a two hand grip on face and mask if needed – get someone else to squeeze the bag if needed

Anaesthetic drugs
Only with a Senior Medical Officer at the bedside.
(But our system allows heroic doses of narcotics and benzodiazepines – which are probably more dangerous. Just don't send someone to Xray with a big dose of opioids on board)
![Page 27: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/27.jpg)
ETT
So for you guys flying solo, an ETT is only for dead people.
LMA very acceptable (for anyone with no gag reflex
If you are intubating we have a video laryngoscope
![Page 28: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/28.jpg)

Stridor
5mg nebulised adrenaline / epinephrine = 5ml ampules of 1:1,000 (unless < 10kg -> 0.5ml/kg of 1,000)
Steroid eg dexamethasone 0.6mg/kg (max 12mg)PO, IM, IV
![Page 30: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/30.jpg)

Anaphylaxis
Mild cases may respond to just nebulised adrenaline, IV fluids, steroids
BUT if in doubt: 0.5mg IM adrenaline + the above
+ steroids eg dexamethasone as for stridor
+/- IV adrenaline eg 5-20mcg (eg 1mg in 1L Normal saline = 1mcg/ml) q 5min or push dose pressors http://emcrit.org/podcasts/bolus-dose-pressors/
+/- Antihistamines

Shock
NZ is a civilised country and so very little penetrating trauma
![Page 40: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/40.jpg)
Shock
Use all your clinical skills to work out what is going on, consider a wide range of causes.
Ultrasound: pneumothorax, blood around heart, blood in abdo
![Page 41: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/41.jpg)
Haemorrhagic shock
Early use of blood products
O neg available immediatelyFFP takes half an hour to thaw - request
earlyPlatelets come by taxi from 1 hour away
Use tranexamic acid 1g IV over 10 minutes then 1g IV over 8 hours
![Page 42: ED orientation Crash Course in Emergency Medicine For junior ED docs Preparation ABCs.](https://reader034.fdocuments.in/reader034/viewer/2022051211/551aaa0a550346e0158b5e95/html5/thumbnails/42.jpg)
Haemorrhagic shock
Trauma o Heamorrhage on the bed, in chest, abdo,
pelvis, long boneo Clinical exam + ultrasound + XRay +/- CT
External haemorrhage -> tourniquet or pressurePelvis or long bone - stabilise with binder or splintChest -> surgeonAbdo -> surgeon but often conservative Mx

Treat specific cause
If not sure: 500ml - 1L of saline likely to help
