CPG Review Flashcards
What is the adult dose of anaphylaxis? What is the repeat timeframe?
What does adrenaline come in?
How would you give the drug?
- 10 microg per kilo up to a maximum of 500 microg. Repeat 5 minutely.
eg. 40 kilo would be 400 microg. - Adrenaline comes as 1 in 1000 - 1mg in 1 ml
- The drug is given neat.
The dose for anaphylaxis for a 3 month old baby, is 50 microg. Explain how you would give this drug?
Draw up 9 ml of saline. Draw up 1000 microg in 1 ml solution of adrenaline. Now diluted, you have 100 microg per ml.
Get a second 1 ml syringe with a drawing needle. Draw up 100 microg in 1 ml. This makes 10 microg per ml.
Give a dose of .5 ml
A patient has a mild oe moderate response to an allergen, the symptoms are:
- Skin rash
- Local allergic reaction
What is the appropriate treatment?
- Universal care and life support -> DRABC + SDE -> History -> Phx -> Medn -> consider oxygenation where appropriate -> Posture -> ECG monitoring -> full set of obs.
- Fexofenadine 180 mg orally
- Transport if required.
What is included in universal care and life support?
Primary Phase:
DRABC + S (send for help = Call for backup) + D (disability = AVPU) + E (exposure)
D - Danger
R- Response
** Control any life threatening haemorrhage immediately.
A- Airway -> Look for obvious obstructions, listen for evidence of airway compromise (Snorus respirations ect)
Correct immediately using:
- Posture
- Manual manouvres (head tilt, chin lift, jaw thrust).
- Suction
- Forceps + Laringoscope if indicated
- Airway devices with consideration of GCS / Gag reflex for aspiration risk.
B - Breathing -> Assess rate, assess WOB, asses depth of respiration. Ausciltate.
- Correct with posture, supplemental 02, PPV if indicated.
C -
- Check radial, if none, check brachial, if none, check corotid.
2. Assess cap Refil centrally + Patient colour.
D - Disability
- Assess patients GCS and note a score.
E - Exposure
- Exposed the patient to identify injuries and management.
- Ensure protection from the elements and management of temperature.
Secondary Phase:
- Hx
- Basic observations on call cases. Advanced or specialist observations where clinically indicated.
- Pain score
- Head to toe physical examinatino of any patient with low or high level trauma.
- Physical examination where clinically appropriate in medical presentations.
- Give special consideration to high risk groups (Paeds, barriatrics, non-english speaking patients, geriatric, co-morbid/complex ect.)
- Comply with ACDs, comply with all patient wishes, expecations and cultural norms where it is possible and reasonable to do so.
What are the criteria for providing adrenaline in anaphylaxis?
TO be provided:
‘In adults with hypotension, severe bronchospasm, or respiratory distress due to angioedema. ‘
What is the treatment protocol for ADULTS with anaphylaxis?
- Universal care and life support -> DRABC + SDE -> History -> Phx -> Medn -> consider oxygenation where appropriate -> Posture -> ECG monitoring -> full set of obs.
- Call for backup-> ICPs can provide hydrocortisone, as well as adrenaline infusion (acctually harder to control exact dose and often less effective than intramuscular. Intramuscular works well due to enhanced endothelial cell permeability -»enhanced blood flow.
- Intermittant positive pressure ventiation with slow rates if required (altered concious status, Unable to maintain an airway -> 10 breaths per minute a good starting point -> One breath every 6 seconds).
- 10 microg per kilo dose of adrenaline IM in the thigh. Maximum dose is 500 microg. Repeat 5 minutely.
- Note time of drug administration
- Saline may be provided to ‘maintain adequate blood pressure’. Consider inadequate blood pressure to be a MAP of <65 -70. A fluid challenge would be indicated according to age and health status.
- NOTIFY the recieving facility.
What is the treatment protocol for PEDES with anaphylaxis?
The same as adult anaphylaxis EXCEPT
- Cannot give fluids
A patient with ‘cardiogenic pulmonary oedema’ what is the treatment protocol?
- Universal care and life support -> DRABC + SDE -> History -> Phx -> Medn -> consider oxygenation where appropriate -> Posture -> ECG monitoring -> full set of obs.
- Early clinical support.
*** ICPs can offer: CPAP, GTN infusion (very effective).
- **Oxygen -> consider additional nasal spec on top of
o2.
***Posture -> Have the patient lean forward and tripod to facilitate breathing
***ECG to assess rate and rhythm. Also to identify potential for cardiac compromise that may underpin the APO episode -> 12 lead is indicated to check for STEMI
- ALL PRE GTN CHECKS:
- Sys BP >100 mmHg + adequate concious state
- No use of erectile dysfunction agents in last 24 - 48 hours —> Cialis (tadalafil), viagra, levitra (vardenafil), sildenafil.
- Check allergies.
- Make sure a 12-lead ECG is done to check for ‘adequate rate and rhythmn’ for providing GTN. Rhythmn should not be preload dependent (Rapid AF, SVT, Inferior STEMI, bradycardia, complete heart block (3rd degree, Bigeminy or trigeminy or quadgeminy). - Consider GTN 400 microg spray sublingual. Repeated 5 minutes PRN.
- Note the time of drug administration.
- Notify recieving hospital + Spine hospital.
Which patients should be considered to have COPD?
The following criteria assume COPD:
- Smoker over 50
WITH
- History of chronic dyspnoea + exacerbated with mild exertion
OR
- A chronic cough with sputum production.
Should you give oxygen to a patient saturating at 80% who is known to be a c02 retainer?
Yes. ‘adequate oxygenation must be assured (88-92%) even if it leads to acute hypercapnia’.
Why is a nuebuliser more effective for COPD patients?
There is no evidence that nebulisers are more effective. However, some patients with severe dysponea may have difficulty using the MDI effectively to achieve drug delivery.
In this case, nebulised medications may facilitate more effective treatment. It is common for severe COPD patients to have their own nebuliser that uses AIR instead of oxygen.
What is a big downside to nebs in COPD patients?
We only have an OXYGEN driven nebuliser. This may exacerbate or potentiate acute hypercapnia. For this reason we have to reassess every 6 minutes.
Remove 02 if possible. However if sats remain <88%…we need to continue despite potential for hypercapnia.
Every COPD patient should be treated as?
Potentially a C02 retainer, and provided oxygen between 88-92% Sp02 until blood gas analysis is completed.
In COPD, what should determine hospital choice?
- Any patient with a history of admission for respiratory illness should be transported to a spine hospital.
- Any patient with COPD who is UNSTABLE should be taken to the NEAREST hospital to stabilise the patient.
Treatment protocol for patients with moderate to severe COPD
AND
An exacerbation?
- Seek a patient management plan if available and follow
- Universal care and life support -> DRABC + SDE -> History -> Phx -> Medn -> consider oxygenation where appropriate -> Posture -> ECG monitoring -> full set of obs.
- Titrate oxygen delivery to 88-92% via NASAL cannula.
- Support - Call for backup in COPD ‘If bronchodilator therapy is ineffective, adequate oxygenation cannot be achieved (02 less than 88-92%), or severe exacerbation of COPD is present’ - Call for ICP backup/CPAP + Rapid transport.
This means backup straight prior to treatment ONLY if the exacerbation is severe. Otherwise, treat, reassess, and then consider backup. CPAP is the primary value add from ICP, however BIPAP is superior and available at hospital.
- Treatment via spacer + MDI.
- Prime spacer (1 x 100 microg)
- Salbutmol (1 puff (100 microg) + 4 inhalations) -> Provide full dose of 1200 microg.
- Provide 8 puffs of ipratropium (20 microg per spray), provide the full dose of 160 microg.
- Repeat salbutamol 20 minutes OR EARLIER if patient fails to improve. A total of 3 doses max. Do no repeat ipratropium.
- NEB only to be used where SPACER is ‘Ineffective or the patient is unable to utilise the device to effect’.
- Neb dose:
- *5 mg salbutamol + 500 microg ipraroptium via oxygen neb
- Limit oxygen exposure to 6 minutes WHERE POSSIBLE.
- Nebs of salbutamol + ipratropium given together/repeated every 20 minutes. Up to a maximum of 3 times.
- Clinicans should be changing back to MDI + Spacer at the earliest opportunity (not oxygen driven).
- Support - Call for backup in COPD ‘If bronchodilator therapy is ineffective, adequate oxygenation cannot be achieved (02 less than 88-92%), or severe exacerbation of COPD is present’ - Call for ICP backup/CPAP + Rapid transport.
- Notify
When should a neb be used in COPD, what is the adult dose?
- Use a neb where ‘MDI has been ineffective OR the patient is unable to utilise the device to effect’
- 5 mg of salbutamol nebulised with 8 litres of oxygen + 500 microg of ipatropium.
- Limit excess oxygen and reassess every 6 minutes with a focus on Sp02, and the patient effect (hopefully an improvement in WOB).
- Repeat of salbutamol and ipatropium can be administered every 20 minutes up to a maximum of 3 doses.
- Change to an MDI at the first opporunity.
- ‘If bronchodilator therapy is ineffective, adequate oxygenation cannot be achieved (02 less than 88-92%), or severe exacerbation of COPD is present’ - Call for ICP backup/CPAP + Rapid transport
Explain fluid protocols for adults in asthma, anaphylaxis, obstructive shock and hypovolemia.
Asthma: Patients only receive fluid in LIFE THREATENING asthma and receive a 500 ml bolus/ fluid challenge. Presumably, more fluids would require a consult if required.
Anaphylaxis: fluid can be provided according to discresion to ‘maintain adequate blood pressure’. This is primarily if they have SYMPTOMS of poor perfusion such as poor cap refill, palor, dizziness ect. Lauren said she would probably start with 100 ml aliquots and reassess.
Obstructive shock and haemorrhagic hypovolaemia: comes under guideline of ‘fluid in medical emergencies’ prior to an arrest. Adults recieve fluid at a rate of discression ONLY until a radial pulse + stable GCS is achieved.
How much fluid would you give for neurogenic shock? What is the criteria?
Criteria: For isolated traumatic spinal cord injury with signs and symptoms of neurogenic shock:
- Aim to maintain normal temperature -> Utilise heat caps, vehicle heater, space blankets + normal blankets.
- Consider SAAS Medical practitioner liason. Request bearly backup of ICP / Medstar as required.
- In neurogenic shock we target MAP of 80 mmHg in adults. Administer saline .9% 250 ml aliquots (in patients >25 kg, aliquots should be 10ml per kilo otherwise). A maximum volume of fluid is 20 ml per kilo.
- In pedes the same saline. 10 ml per kilo, up to a max of 20 ml per kilo. No MAP guidance is specified. Contact EOC medical practitioner for guidance.
What is the treatment protocol for crushed patients?
- Request clinical support + Universal care and life support
- Remove the object as soon as possible, but only once prepared to manage subsequent hypotension (also consider other factors such as vac mat, ct6, pelvic binder). Hypotension is very rare in crush injuries less than 4-6 hours.
- Large bore cannula access bilaterally if possible.
What differs with pregnant patients as it pertains to hospital choice?
If it is TRAUMA involving a pregnant patient, Flinders is the only hospital that can treat both mum AND bubs. If it is MINOR than LMH is acceptable. Women’s and children’s will not want this patient.
What amount of fluid do we give to a brown snake bite, when the patient BP is 80/60, but has a palpable radial pulse and stable GCS?
He may be in haemorrhagic shock, potentially due to DIC. However bending the CPG that far for giving fluid is incorrect. Consult for ECP to ask permission for fluids.
Do all patients with head injuries get treated with the ‘severe head injury’ guideline?
No. Only patients with severe head injuries.
A severe head injury is when GCS IS LESS than 10
What are key considerations in using hydrogel products in burn cases?
- Hydrogel should not be used in chemical burns
- Hydrogel is always a secondary option if running water is not available. Unless it’s an airway burn in which extrication is the priority, and hence hydrogel will be used as a primary cooling option.
- You can only use hydrogel for 10 minutes on a pede. For an adult it is 20 minutes.
- Hydrogel products need to be removed before application of cling wrap.
- After cling wrap is applied, cooling can occur over the top with saline. Reassess temperature.
What is the treatment for a patient with signs of airway burn?
- Universal care and life support -> DRABC + SDE -> History -> Phx -> Medn -> consider oxygenation where appropriate -> Posture -> ECG monitoring -> full set of obs.
- Do not forget as part of basic care -> Allergies, Past medical history, medications.
- Consider MEDSTAR + ICP.
ICP can offer:
- Enhanced pain relief with ketamine
- Cricothyrotomy
- Escharaotomy (circumferential burns)
Medstar can offer:
- RSI
- Cricothyrotomy
- Immediate extrication. NEAREST hospital.
- You can SKIP all cooling for an airway burn. Cooling with burn-aid can occur en-route. Followup with glad wrap - loose. Can continue cooling with saline post glad wrap (over the top)
- Pain relief - Consider withholding paracetamol if difficulty swallowing. Check swallow. Check BLOOD pressure to see if elligble for fentanyl. Fentanyl given 5 minutely. 50 microg doses likely.
- Fluids -> calculate park-lands formula. We only give the first 50% of the park-lands total which can be given in the first 8 hours. The CPG Aim is to ‘re-establish and maintain normovolemia’.
- Monitor for hypothermia. Reassessment of temperature is key.
- For pedes consider transport to WHS for burns and for adults the RAH is the burn centre.
